Day 656

Quotes / HN

I think part of the problem is people being raised to believe that love, in the biochemical sense, is the most important part of a relationship. Hence when they start feeling similar feelings for others, their relationship can weaken. But a relationship can be about so much more than just the biochemical side: two people, with similar goals and values, working together to build a better life for themselves and their children, and to help each-other achieve their dreams. 1

Added zsh alias for copying current dir

alias ccd='pwd | xc'; though I kinda feel the task would be solved nicely as keyboard shortcut for kitty. + Reminder to myself that zsh nicely cd-s to it when pasting the folder, without cd.

Also find | grep is now f instead of ff.

Intellij Idea Ideavim actionlist

And yet another place to find this! :actionlist as command in ideavim.

Ideavim jump to place of last edit

IdeaVIM Help: motion is the last readable docu I can find, from 2006.

gi starts insert mode at the last place insert mode was exited; '^ just moves the cursor there.

Intellij Idea tests not running

Had an issue with “Class not found” when running tests, fixed with “Invalidate caches and restart”

Intellij up/down keys

My custom up/down keys set via xmodmap (<Super-C> etc.) got recognized everywhere in the OS except intellij; Can get configured in intellij keymap.


Day 652

Intellij idea toolbars

“View -> Appearance -> Tool window bars” gives extremely useful tool window bars that include a number, the one I can use in <Alt-N> bindings to make them appear! Same goes for the …tabs to the right with Structure etc.

Intellij building complex stuff and running maven goals

Once N maven goals or whatever are run and N tabs opened, they can be found again in the “Run” tool window bar (<Alt-4>). Particular tabs can be also successfully restarted.

maven skip checkstyle

mvn [target] -Dcheckstyle.skip does the magic without editing any POMs etc. 1

scp can do autocompletion!

Nothing to add, but I think it works if you have access via public key instead of passwords. scp what-ever:/home/whatever/..<TAB> works nicely with zsh even visualizing it like usual.

Also TODO rsync apparently can do the same things as scp, but better, I should give it a chance.

Pandas / matplotlib

It’s possible use panda’s graphs as an ax and do all other modifications to it!

ax = data.plot(y=['tp','fn'], kind='bar',stacked='true')

jupyter / mpl / google docs

You can drag and drop graphs directly from jupyter into a google docs presentation


Day 647

grep / uniq magic

uniq can compare stuff before / after N characters in the string, group together duplicate ones, etc!

  • uniq -w N looks at only the N first characters.
  • uniq -s N don’tt look at the first N characters
  • uniq --all-repeated[=METHOD] prints all duplicated lines and optionally separates them via METHOD. separate is really nice as method.
  • uniq -c prefixes line by number of occurrences of that line

And I guess again - uniq works only on sorted data.

vim folding by tab works again now!

Had to remove this snipped from vimrc:

augroup remember_folds
  autocmd!
  autocmd BufWinLeave *.* mkview
  autocmd BufWinEnter *.* loadview
augroup END

vim folding

Will now try to use almost exclusively folding by tabs. For this, these are going to be helpful: 1

zo		Open one fold under the cursor.  
zc		Close one fold under the cursor.  

zO		Open all folds under the cursor recursively.  
zC		Close all folds under the cursor recursively.  

za		When on a closed fold: open it.  
		When on an open fold: close it 
zA		When on a closed fold: open it recursively.
		When on an open fold: close it recursively 

zv		View cursor line: Open just enough folds to make the line in
		which the cursor is located not folded.

zX		Undo manually opened and closed folds: re-apply 'foldlevel'.
		Also forces recomputing folds, like |zx|.


zm		Fold more: Subtract one from 'foldlevel'.  
zM		Close all folds: set 'foldlevel' to 0.


zr		Reduce folding: Add one to 'foldlevel'.
zR		Open all folds.  This sets 'foldlevel' to highest fold level.


zn		Fold none: reset 'foldenable'.  All folds will be open.
zN		Fold normal: set 'foldenable'.  All folds will be as they
		were before.
zi		Invert 'foldenable'.


MOVING OVER FOLDS 

[z		Move to the start of the current open fold.  
]z		Move to the end of the current open fold.  
zj		Move downwards to the start of the next fold. 
zk		Move upwards to the end of the previous fold.  

TODO and XXX conventions

    hi link nodo javaScript
    syn match todo /\s*TODO.*$/

How to prettyfy json using jq

jq . inputfile.json gives a nice pretty colored indented output.

screen attaching non-existing named screens creates them

If I do screen -R 20, and there’s no screen named ‘20’, such a screen will be created and attached. Neat.

Day 640

i3 shortcuts for monitors

Remembered about and updated the shortcuts for focusing the different monitors:

# focus outputs screen
bindsym $ms+a focus output eDP-1
bindsym $ms+o focus output HDMI-2
bindsym $ms+e focus output DP-1-1

Connected to me remembering about the tabbed layout:

# change container layout (stacked, tabbed, toggle split)
bindsym $ms+s layout stacking
bindsym $ms+Shift+t layout tabbed
bindsym $ms+Shift+s layout toggle split

takes less space than my usual stacked, but makes it hard to focus a different screen via left/right - until now.

bash rm multiple folders

For removing multiple folders if it has to be done often, and the folders may or may not be there, esp. with wildcards, current best option I found is not to do rm -rf one/* two/*something* three but rm -rf one/* && rm -rf two/*something* && rm -rf three. If one breaks the other ones will still run.

zsh removing an alias + zsh feature of ‘you sure you want to delete all N files from… ‘ + rm -r **

  • unalias rm 1
  • The feature can be removed by an option, but this is nice:

    rm -rf **

Works for me too.

head / tail starting from an offset

bash - Linux head/tail with offset - Stack Overflow:

 -n, --lines=K
        output the last K lines, instead of the last 10; 
        or use -n +K to output lines starting with the Kth

You can therefore use ... | tail -n +2 | head -n 3 to get 3 lines starting from line 2.

Simple but effective. tail -n +N does tail starting from linenumber N.

Intellij idea search / find

Search is search, but “find in path” (and some other stuff) is find. I wonder if there’s a meaningful semantic difference in there. Semantic difference between Find and Search? - Stack Overflow has the logical ones, but I can’t connect it to how intellij idea uses them.

Java logical operators shorct-circuiting

The && and || operators “short-circuit”, meaning they don’t evaluate the right-hand side if it isn’t necessary. The & and | operators, when used as logical operators, always evaluate both sides.

There is only one case of short-circuiting for each operator, and they are:

  • false && ... - it is not necessary to know what the right-hand side is because the result can only be false regardless of the value there
  • true || ... - it is not necessary to know what the right-hand side is because the result can only be true regardless of the value there. 1

Stand-off markup (NLP)

Stand-off markup (also known as remote markup or stand-off annotation) is the kind of markup that resides in a location different from the location of the data being described by it. It is thus the opposite of inline markup, where data and annotations are intermingled within a single location. 2

The wiki it’s from is also nice: TEIWiki It’s All pages - TEIWiki would be interesting to look through, NB it has a non-intuitive “next page” link there.

Java declaring variables inside or outside a loop

Intellij idea enable VCS integration

From Error on openjdk11, cannot find javadoc · Issue #26 · chenjianjx/wsdl2html · GitHub: export JAVA_HOME=$(readlink -f /usr/bin/javac | sed "s:/bin/javac::")

readlink resolves symlinks. Alone it just gives you the file the symlink points to. readlink -f follows each and every symlink to the very end. On my box, the difference is:

me:~/ $ readlink /usr/bin/javac     
/etc/alternatives/javac
me:~/ $ readlink -f /usr/bin/javac

vim antipatterns w vs e + vim movements

I should use e much more than w, as that’s what I really usually need. And in general I should take the time to get to know better the tools I’m constantly using. I guess ‘right’ vim is something like ‘right’ typing.

Also, never used them like this, but c of course takes all movements, so changing next two lines or changing from cursor to beginning of the line also works.

kitty paste to terminal and copy url hints

Added this to config: map kitty_mod+p>c kitten hints --type path --program @ - copies hinted URL to clipboard.

This gets rid of so much copypasting oh my God.

vim regex separator

I have been using \s as “word separator”, this is wrong. \s in vim is just a whitespace character - so tabs, spaces etc. For what I usually want, \A is any non-alphabetic-character. (\a being an alphabetic one).

vim regex inverse match capturing group + ‘very magic’ mode

/\vcat (dog)@!
/cat \(dog\)\@!

First one is very magic, second is the same without it. @! is a negative match to the preceding capturing group (could have been (\1) too).

\v activates “very magic” mode where everything except letters and underscore has special meaning. This is actually going to be very handy. 1

I’ve actually been using regexes quite a lot lately, have no idea how I lived without them when parsing very big log and text files.

vim paste last searched regex

:s/<Ctrl-R>/ inserts the last searched for regex between the slashes. This is wonderful and no more copypasting stuff! 1

Intellij idea checkstyle tests

In settings, you can configure checkstyle to run everywhere [not] including tests. If you don’t include tests, you won’t get to ‘run checkstyle on the current file’.

i3 vertical tabbed windows

If I have windows that are tabs stacked vertically to make it not-a-tab-anymore I just have to move it one level above or below tabs. If it’s stack 3/3, amking it 4/3 would make it the bottom part of a split whose top part is vertical tabs.

zsh evil registers

Intellij idea read-only decompiled class sources

.. predictably, “Download sources” makes them downloaded, readable and debuggable.

Also nice is the “Alternative source available for” - todo understand how exactly do poms, sources, etc etc etc. play with all this. I assume if maven module wants X, and X can be found in maven and in the list of dependencies in Intellij, I get this choice?


Day 617

zsh prompt changes

To continue the idea to make it easier to record my steps, did some changes to the clean oh-my-zsh theme. For this, I made a copy of the theme file /home/%username%/.oh-my-zsh/themes/clean2.zsh-theme, and using zsh: 13 Prompt Expansion added the following:

  • history event number at the end of the prompt, after the time (RPROMPT='%*/%!')
  • Added the last N elements in the path while leaving tilde contraction. (PROMPT='%{$fg[$NCOLOR]%}%B%n%b%{$reset_color%}:%{$fg[blue]%}%B%5c/%b%{$reset_color%} $(git_prompt_info)%(!.#.$) ', the number 5 represents the number of directories to show.)

Now the prompt looks like this:

%username%:~/o/dtb/assets/pics/ (master✗) $                                                             16:14:10/10548

timewarrior :quarter

Timewarrior has many interesting hints, I always missed something with now and previous month - of course :quarter exists.


Day 616

Disabling wifi to use ethernet

This should have been done long ago but discovered this now. If I have both a wiki and ethernet and want to stop connecting to the wifi, disconnecting from the endpoint is much less reliable than disabling wifi alltogether.

fc and history

fc also accepts the history number of the command to edit and run. So fc 1238, for example.

Ideavim map for <Esc>

Quite often, especially in the commit window, I want to use Ideavim’s normal/command mode, but <Esc> gets intercepted by Idea and closes the commit window. My old mapping works though:

imap jj <Esc>

in .ideavimrc.

zsh share registers with OS when copypasting

Now I can yank stuff from the zsh command line and paste them in other applications etc.


Day 613

Finally fixed the date / time / tztime saga

Looked into the TZ environment variable, it’s the overwritten “Berlin” one. I forgot I had this beauty in .zshrc: export TZ="/usr/share/zoneinfo/Europe/Berlin"

Probably a relict of an old hacky way to set time when I couldn’t do it properly.

Interestingly, even i3status listened to it (how? why? At which point does it access zsh environment variables? Are environment variables zsh-specific and accessible to things started by/within zsh? How does this work? TODO). And interestingly, restarting zsh didn’t get date to output the right date, even with the right timezone set, I had to close and reopen the terminal.

Removed that line, restarted i3, now all times are set right and I can remove timezone info from my timestamps.

Vim insert time and date - updated mappings

imap <leader>d <esc>:put =strftime('%c')<cr>kJA
imap <leader>t <esc>:put =strftime('%H:%M:%S')<cr>kJA

They look like this:

Qutebrowser / vim copypaste

If I’m copypasting something from vim with yW it copies the space after the last word. If I then paste it into the search of qutebrowser it won’t find anything if the string in the page doesn’t have a space after it.

git diff CSVs at field level

git diff --color-words="[^[:space:],]+" 1

daff tool for diff-ing CSVs

Daff is a “library for comparing tables, producing a summary of differences”. GitHub - paulfitz/daff: align and compare tables

It actually does a really nice visualization with colours, like that script I wrote a long time ago. Leaves field numbers too. In general it’s awesome.

More options available with the full form: daff diff --id field --padding sparse file1 file2 Has a lot of output formats!

Even ordered/unordered works, if you don’t set the wrong id column.

Vim folds empty line

To make the markers marking folds easier to edit, one can select an empty line at the end of zf, they will end up on a line by themselves, and you can happily paste stuff inside the fold.


Day 612

New shiny zsh alias

ff is now find | grep

i3 run and show windows

# bindsym $ms+d exec --no-startup-id i3-dmenu-desktop
bindsym $ms+d exec rofi -show run

# select windown
bindsym $ms+g exec rofi -show window

in i3/config. Rofi is nice and I forgot about it. Added a list of windows on $ms+g so that it’s similar to my qutebrowser keybinding.

Dependencies scopes in Intellij Idea

The default, “Compile”, is the “strongest”. Module dependencies - Help | IntelliJ IDEA contains a really nice table summarizing compile/test/runtime/provided.

Running a single test in maven

mvn -Dtest=UsersServiceImplTest test for all tests in that class, but you can also do wildcards and single test (yourclass#yourtest test) 1

Intellij idea module dependencies order

Order is important and whichever is the first will be used.

You can change the order in the GUI, but you can move them one step above and you can’t move multiple dependencies at the same time. Of course if you add a new one it goes to the veeeery end.

You can edit the configuration manually, inside the project it’s the .iml file that can be edited via whatever.

Get column in bash with cut

This is a thing that keeps coming up, TODO anki

awk - bash: shortest way to get n-th column of output - Stack Overflow

cut -f2 accesses the second field. -d is for delimiters, if not equal to tab.

fex.net

Fex.net seems to be an OK service for sharing stuff, S. used it for wedding pictures and A. used it for uploading an .iso, both worked well.


Day 611

Libreoffice Calc opening files with default import settings

For multiple files with known settings, such as separator, decimal etc., libreoffice --calc mydata.csv --infilter=”CSV:44,34,0,1,4/2/1”

  1. Separator, 44 is the ASCII value of comma
  2. Text delimiter, 34 is the ASCII value of double quote
  3. Character set to use, 0 is the system default
  4. Line number to start conversion. I have no header line, so it is 1
  5. Cell format per column, separated by /. It does not seem to matter if there are a different number of columns in the data: Extra columns default to Standard, extra formats are ignored. 4 = date d/m/y; 2 = text; 1 = standard 1

Full documentation for infilter is here: Filter Options - Apache OpenOffice Wiki

Jekyll mixing html and markdown

I have to remember that putting markdown stuff inside HTML tags won’t work, like with the Actionlist yesterday.

git diff to stdin

Is it possible to git-diff a file against standard input? - Stack Overflow:

echo foo | git diff --no-index -- my_file -

Since git 1.5.1 there’s been an option to diff against stdin - it’s just not been documented

Day 610

x-www-browser and qutebrowser

If qutebrowser is not running and I click a link, another instance will be started, and it looks like this: myusername+ 19648 10.8 2.7 6125248 896828 ? Sl 12:10 10:07 /usr/bin/python3 /usr/bin/x-www-browser https://the-link-i-click.ed; I can’t find it easily as the process doesn’t contain the string qutebrowser.

zsh theme

Changed it to clean, now I get the time when I ran commands. I so missed this, not sure when it all went wrong.

zsh history with datetime

history -E shows time and date when a command was run.

I really think I need something like a lab notebook approach to all my work experiments, this is a good step for this. So many terminals around with so much stuff run with different parameters and no way to track it.

history -E:

 7932  1.9.2020 18:11  history
 7933  1.9.2020 18:11  vim ~/.zshrc
 7934  1.9.2020 18:11  zsh
 7935  1.9.2020 18:11  ls
 7936  1.9.2020 18:13  pwd
 7937  1.9.2020 18:13  ls
 7938  1.9.2020 18:13  cd newkotlin-newusecase
 7939  1.9.2020 18:13  pwd | xc
 7940  1.9.2020 18:13  ls
 7941  1.9.2020 18:13  history -E
 7942  1.9.2020 18:15  vim ~/.zshrc
 7943  1.9.2020 18:15  zsh

Outputs only the latest items though. But it accepts a start parameter, so history -E 0 gives me what I need.

Also I didn’t fix the time last time apparently, date still disagrees with tztime, whatever I did last time was a temporary fix. Will be printing timezone info starting from now on.

Now I have a couple more default aliases:

alias h='history -E 1 | grep'
alias hh='history -E 1'
alias g='grep'

zsh alias for date in filenames/commands

alias sht='date +"%m%d-%H%M%S%z"'

Now I can do whatevercommand -o outputfile-$(sht) and it will paste a datetime like outputfile-0901-182113+0300 automatically.

curl quiet mode

The magic for waiting for files will be now

watch curl -I -s http://somefile | grep 200

interestingly, echo watch "curl ..." | xc which xc being clipboard gave me a string without "s, not sure at which step they got removed but it might bite me in the future.

Real command is watch "curl -I -s http://somefile | grep 200". . -s makes it show no progress bars etc.


Day 609

German

  • nachschlagen - look sth. up, retaliation, consult something quickly. TODO anki
  • massig - bulky, massive, huge. (“Massiges Gehalt”)

Intellij idea split tabs

Intellij Idea has ‘unsplit’ lower than all the other tab options :)

TODO English

Finally remember how many “d”s and “s”s are there in address. TODO anki

Intellij idea reopen closed tab

Like in browsers, it’s <Ctrl-Shift-T>; Also now it’s also u like in qutebrowser: map <leader>u :action ReopenClosedTab<CR>

Edit: Why doesn’t it work? TODO

Intellij idea / pycharm environment variables

You can copypaste the environment variables in the running configuration, including from system ones that get included to the custom ones, it understands what you want.

Day 608

Random / interesting / ideas

Emoji Simulator! 😘 -> generally, emojis are a nice way to convey information, instead of colour. Not nice but at least novel and ineresting. It would be nice to work them into some project or visualization. Мамо чому я не фронтендщик.


Day 606

Git revert vs reset last N commits

Resetting, Checking Out & Reverting | Atlassian Git Tutorial is a nice guide about ways to undo some of the commits. Reset is a harder way to undo stuff that sometimes leaves no traces, Revert is a way to create a commit that undoes the last N commits, so history is preserved and that’s good.

A way to revert the last N commits is this: 1

git revert --no-commit HEAD~3..

Two dots at the end are significant:

@cardamom Those specify a range. HEAD~3.. is the same as HEAD~3..HEAD

A saga about timezones

So. I wanted to change time back to Berlin time from Ukrainian time.

Something was wrong.

~ → timedatectl status
                      Local time: Fr 2020-08-28 18:50:55 EEST
                  Universal time: Fr 2020-08-28 15:50:55 UTC
                        RTC time: Fr 2020-08-28 15:50:55
                       Time zone: Europe/Berlin (EEST, +0300)
       System clock synchronized: yes
systemd-timesyncd.service active: yes
                 RTC in local TZ: no

UTC is right, time zone is right, but local time is wrong.

Then I google and see that Europe/Berlin is actually EEST, +0200!

Then I realize the following:

Last time I needed to change the time, I changed the timezone, by doing:

sudo cp /usr/share/zoneinfo/Europe/Kiev /etc/localtime

(#Kyivnotkiev)

/etc/localtime was a SYMBOLIC LINK to /usr/share/zoneinfo/Europe/Berlin

~ → file /etc/localtime
/etc/localtime: symbolic link to ../usr/share/zoneinfo/Europe/Berlin

By doing that, I rewrote the Berlin timezone by making it Kyiv, changing the time on my computer and changing the Berlin timezone itself.

Fixed this with a bandaid by making my timezone Europe/Rome, as /usr/share/zoneinfo/Europe/Rome was never overwritten.

↑130 ~ → timedatectl status
                      Local time: Fr 2020-08-28 17:59:15 CEST
                  Universal time: Fr 2020-08-28 15:59:15 UTC
                        RTC time: Fr 2020-08-28 15:59:15
                       Time zone: Europe/Rome (CEST, +0200)
       System clock synchronized: yes
systemd-timesyncd.service active: yes
                 RTC in local TZ: no

Happy end.


Day 604

VPN DNS issues

Seemed to have a conflict w/ IPv6 VPN vs the IPv4 one, first had priority. Then I had an issue where the VPN IP was the same as the IP of my router. Fixed by moving router IP. Learned a lot about how DNS works.

Lookup website using particular DNS

  • nslookup somewebsite.com 8.8.8.8 looks up the website using the provided 8.8.8.8 DNS server.
  • systemd-resolve --status gives the current DNS settings.
  • sudo systemd-resolve --flush-caches flushes the DNS caches.

Day 589

git diff with full context

How to get git diff with full context? - Stack Overflow - git diff -U1000000 - or wc -l in place of the number - any number of line larger than the file works.

Intellij idea test results CLI output w/ ideavim

The window w/ CLI output or test output can be happily manipulated with ideavim! Now I can copypaste everything easily!


Day 586

Jupyter Notebook vim mode

When operating on cells, not text (= not insert mode), the usual j/k commands select cells when shift is used (J/K). This is neat. I should read the documentation.

Java brackets in for statements

If you have only one statement in for loops, you can drop the brackets:

for (final String dt: distanceTypes)
    for (final double co : cutoffs)
        your_one_statement();

That said, it’s not a good idea :) Answer has details about the definitions, default scope for for is next statement. A statement can have brackets.

for loop without braces in java - Stack Overflow

Ideas / TODO / Fiamma / PKM

Possibly sometime rewrite my link wiki (pchr8.net/f/)’s bookmarking userscript to accept data as title/complexity/rating/tag1 two three/Cat1 cat2 cat3 instead of the current multiline thingy, might be even easier to fit it into a userprompt

Random / interesting


Day 585

Jaro-winkler similarity for empty strings (#nlp)

Jaro-Winkler handling empty strings · Issue #28 · tdebatty/java-string-similarity - TL;DR officially ‘undefined’, what has to be returned in implementations depends on why you need it. These are nice edge cases I have to learn to watch for.

String similarity algo explained

String simularity has a nice table with similarity algos and how they perform with different changes.

String sim algorithms.


Day 584

Git diff

Is much more flexible than expected. git diff --unified=0 doesn’t show the context lines, only the changed ones; in general the documentation is worth reading, could be a good tool to add to my belt for various one-off tasks.

pandas convert entire dataframe to str / value type

df.applymap(str) converts everythnig to str. df.applymap() applies a function to a Dataframe elementwise. (TODO anki)

pandas import numpy

If I don’t want to do import numpy as np separately (for things like np.nan), pd.np.nan works! 1

pandas remove NaN/nan in str

np.nan in the dataframe can be removed w/ df.fillna(''), but after getting converted to string the NaN become nan and have to be removed by the string operation. As a string operation, it’s important to watch out for strings containing nans, for example:

pd.DataFrame({'one':['two','three','four',pd.np.nan,23,'nonanme']}).applymap(str).replace('nan','',regex=True) would change the last element. All answers here seem to have this issue.

So to remove them from a string representation, pd.DataFrame({'one':['two','three','four',pd.np.nan,23,'nonanme']}).applymap(str).replace('^nan$','',regex=True) works, with a regex for nan.

qutebrowser leave passthrough mode

Changed keybinding to config.bind('<Ctrl-Shift-+>', 'leave-mode', mode='passthrough'), which translates to <C-S-=>, but it seems to see = as + because Shift is being pressed.


Day 583

Diff character-level differences highlights

command line - Using ‘diff’ (or anything else) to get character-level diff between text files - Stack Overflow gives this one nice string: git diff --word-diff=color --word-diff-regex=. file1 file2 which gives red/green characters for deletions/additions. Also, chaining greps also works nicely with grep -o which passes only the text of the actual match. Grep doesn’t support capturing groups.


Day 582

Intellij idea CheckStyle plugin

CheckStyle-IDEA - plugin for IntelliJ IDEA and Android Studio | JetBrains exists and I had better luck w/ it than with importing the checkstyle file from Style in Settings. Gives highlights inside the code itself automatically.

Intellij idea - “Add comment” style - put them before the text, not at first column

  • Can be set in “Code generation”: Action gets used w/ Ideavim’s gcc etc.

    To configure settings for where the generated line or block comments should be placed in Java, in the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Code Style | Java and on the Code Generation tab use options in the Comment Code section. 1

Intellij Idea Checkstyle highlights

Intellij Idea Checkstyle highlights seem to refresh when I change a character and similar edits, but not when I change indentation w/ IdeaVim.

Intellij idea Rainbow CSV plugin

Rainbow CSV plugin is nice and highlights columns of the CSV in different colours - something I didn’t know I needed.

Checkstyle documentation

checkstyle – Imports explains (“Rationale:”) the rules used and in general is quite well-written.

Checkstyle equalsavoidnull

"My_Sweet_String".equals(nullString); is the way to go for string comparisons apparently, it avoids potential nullPointerExceptions. 2

String similarity algorithms in Java

tdebatty/java-string-similarity: Implementation of various string similarity and distance algorithms: Levenshtein, Jaro-winkler, n-Gram, Q-Gram, Jaccard index, Longest Common Subsequence edit distance, cosine similarity … is awesome.

A library implementing different string similarity and distance measures. A dozen of algorithms (including Levenshtein edit distance and sibblings, Jaro-Winkler, Longest Common Subsequence, cosine similarity etc.) are currently implemented.

String similarity / string distances normalization #nlp

algorithm - Normalizing the edit distance - Stack Overflow has info about normalizing distances like Levenshtein etc. And how a normalized distance is not a metric anymore, as it violates the Triangle inequality w/ sum of two sides of the triangle not being longer than the third.

Longest common subsequence

Longest common subsequence problem - Wikipedia is different from Longest Common Substring is that subsequences are not required to be uninterrupted.

Day 571

Intellij idea breakpoints with no executable code

So here’s a nice difference w/ Python - in Python, you can set breakpoints everywhere, and you can add something random after the line you want to look at if it’s the last line of the function. In java, I assume some pointless lines are optimized away or considered uninteresting, but you can set a breakpoint to the } bracket and the end of the function if it’s on a line alone.

(Have yet to find a way to nicely output multiple values in the debugger though.)

Intellij idea “Execute code” during debugging

What I could do in Python with 2, 3, 'test', function() I can do in Java by returning an array or whatever, with

Random / quotes / coronavirus

People seem to have a naïve view of what “cured” means: someone “gets sick”, is treated, and then returns to the status quo ante. Thus there is little concern about catching the disease (or any disease) when you are not in an “at risk” group.

But hospital discharge just means the treatment you get stops being worth the time/money. Ideally you finish convalescing at home. But any consequential damage isn’t ignored, as if you just had had a dented panel replaced on your car.

Once I understood this error some of the discussion about dealing with the virus made sense.1

Identify an unknown process in linux

exe symlink pointed to /usr/sbin/huntd, which was easy to Google, and which turned up to be one of the bsdgames I tested earlier that still had its daemon running. I’ll remember this trick.

Day 556

Random / Interesting / patterns

“If it takes water lilies that double their spread every day 50 days to cover the entire lake, on what day would they cover a half of that lake?”

The answer, obviously, is day 49. More to the point, day 45 would have had only seen the lilies cover 3,125% of the lake. Day 40 would have had been 0,0976% - from that little of an amount, the lilies would proceed to take over the entire lake in 10 more days.

So, it’s the same way with this pandemic. I think there now enough of an evidence from anywhere in the world to say that absent an (effective, early) intervention to lower R0 inside the country, it takes about 3,5 months for the virus to blow up into a devastating contagion. 1

Intellij idea environment variables

Intellij reads environment variables only at startup, and there’s no way to refresh them. Even “Restart”-ing it via the menu didn’t help, I think I need to physically restart the process.

UPD: Even restarting the process doesn’t work if I don’t (re)start zsh (and make it read the new variables in .zshrc) in the terminal where it’s running! Which actually makes sense.

Intellij idea git annotate

Java jar/fatjar shaded dependency

libraries - What is a shaded Java dependency? - Software Engineering Stack Exchange

Shading dependencies is the process of including and renaming dependencies (thus relocating the classes & rewriting affected bytecode & resources) to create a private copy that you bundle alongside your own code.

To Shade a library is to take the contents files of said library, put them in your own jar, and change their package. This is different from packaging which is simply shipping the libraries files in side your own jar without relocating them to a different package.

Java subclassing something w/ private fields

java - Do subclasses inherit private fields? - Stack Overflow is pretty split by opinions. TL;DR they are inherited as they are used by the methods in the superclass, but you can’t use them in the subclass.o

Since the subclass can’t access or modify the private fields, then, in other words, they are not inherited. But there really is just one object, it really does contain the private fields.

So classes do not inherit them, but the object does. And the JLS (Java SE Specifications) is the Bible.

Python generator expressions are a thing

How to Use Generators and yield in Python – Real Python:

The second one is a generator expression, with all the nice memory thingsies that entails.

In general How to Stand Out in a Python Coding Interview – Real Python has some very interesting bits I had no idea about.

And from “Dive into python”, p.193:

Using a generator expression instead of a list comprehension can save both RAM and CPU. If you’re building an list just to throw it away (e.g. passing it to tuple() or set()), use a generator expression instead!

Generator expressions are functionally equivalent to generator functions.

#!/usr/bin/env python and the env trick for running stuff

From the Learning Python 5th Edition book, Chapter 3 page 60:

#!/usr/bin/env python
...script goes here...

This is fascinating. The env $whatever command returns the location of $whatever, which may or may not be standard. And apparently this is the way to write trueъ portable scripts.

This goes to show that reading some nice reference line-by-line is actually a good thing if you have basic random bits of knowledge about something.

So currently:

  • Finish Diving into Python, at least the parts I feel are relevant If I decide I need more Python in my life,
  • Learning Python 5th edition, 1594 pages, focuses on the Python language which is the official prerequisite to…
  • Programming Python, 1628 pages. It focuses on libraries and tools.

Day 501

Port knocking and using ports based on IP

My latest trick for deciding on external ports to forward is to combine the service port and the device’s internal IP address. If my desktop was 10.0.1.36 and the service was SSH on port 22, the external port would be 22136. So far it’s worked well, but it only really works if you force your router to only give out 10.0.1.2 through 10.0.1.99. (snazz @ Port knocking | Hacker News)

Also: Port knocking is a method of externally opening ports on a firewall by generating a connection attempt on a set of prespecified closed ports. Once a correct sequence of connection attempts is received, the firewall rules are dynamically modified to allow the host which sent the connection attempts to connect over specific port(s). 1

Rsync to slash or not to slash

This definitely goes into anki: Rsync – To Slash or Not To Slash? – Rants & Raves – The Blog!

Without a slash on the source directory means copy both the source directory, and the contents (recursively if specified) to the destination directory while adding a trailing slash means only copy the contents of the source directory, recursively if specified, to the destination. Without a slash on the source directory means copy both the source directory, and the contents (recursively if specified) to the destination directory while adding a trailing slash means only copy the contents of the source directory, recursively if specified, to the destination.

TL;DR: #anki

  • Source directory:
    • Slash: copy the contents of the source directory, without the directory itself
    • No slash: copy both the directory and its files
  • Destination directory: doesn’t matter

The difference between /target/source/source_content and /target/source_content.

Usually I want slash.

To memorize, the slash represents the contents of the directory in some way.

Also nice handy command tree that I didn’t know I needed.

Хештег - Як перекладається слово Хештег українською - Словотвір

З огляду на технічну складову питання додам коротке обґрунтування назви “кришмітка”. Слово hash-tag отримало таку назву не просто із-за символа “решітка”, причиною використання цього символа є скорочення написання слова hash-tag, коріння якого по своїй суті заходить глибоко в науку про компьютери. Розробники використовють слово hash як скорочення слова dictionary (словничок) що є спеціальною структурою даних котра пришвидшує пошук. Hash-tag або “#tag” з технічної точки зору означає те що слово “tag” проіндексується (потрапить у індекс або іншими словами словничок) і надалі буде доступне для швидкого пошуку. Тепер про саме слово hash, у тій же компьютерній науці існує багато стуктур даних здатних виконувати роль словничка. Hash-словнички особливі тим що використовують спеціальну hash-функцію, котра дозволяє отримувати інформацію із найменшою кількістю дій над словничком (аналогія дії - перелистування сторінок словника, що є вкрай повільним). Hash-фунція на основі вхідної послідовності символів (текста чи слова) підраховує число. Якісна hash-функція буде генерувати числа особливим чином, якщо в тексті замінити бодай одну літеру число має змінитися кардинально, але визначальним є те що якщо на вхід подавати одну і ту ж саму послідовність число має залишитися незмінним. Таким чином після того як ваша послідовність символів потрапила у словничок, вам не потрібно гортати його сторінки для того щоб знайти необхідний ключ, ви підраховуєте хеш-функцію яка вам повертає номер сторінки де має знаходитись слово. Hash-функція отримала таку назву із-за дій що вона виконує над вхідними данними всередині себе. Фактично вона “кришить”, “рубає”, “перемішує”, “заплутує” вхідні данні, що відповідає англійському перекладу слова hash. Тобто логічним було б перекласти слово хеш у цьому контексті як “криш” або “міш”. Переклад слова “tag” вже здійснений, і це “мітка”, поєднавши ці варіанти отримаємо “кришмітка” що в одночас володіє певною милозвучністю.

“Кришітка” є спрощеним варіантом новотвору “кришмітка”, запропонованого Денисом Яремовим. Але має кілька суттєвих переваг: 1) Милозвучніше; 2) Відповідає етимології (криш-мітка); 3) І до того ж співзвучне з назвою самого символу # - “решітка”.

Знову захотілося писати Соломку українською мовою, просто щоб мати змогу використовувати слово “кришітка” :)

/g/ - Let’s collect here programming books that are unusual in some sense, be it their approach, presentation, or simply just quality. “The little schemer” has a nice dialog-like structure, and I find this very interesting. I wonder if there are any other similar books (or threads).

Editing bash scripts

Take care editing bash scripts

Well, after the 30 seconds elapses, the running script deletes all of my files. This happens because bash reads the content of the script in chunks as it executes, tracking where it’s up to with a byte offset. When I delete one character from the sleep line, the “next command” offset points at the r in #rm instead of the #. From the interpreter’s point of view, the # shifts backwards onto the previous line so it runs the unfortunate command.

And as a bonus, ,w now takes me to the wayback machine for that page:

config.bind(",w", ":jseval javascript:location.href='https://web.archive.org/web/*/'+location.href")

Anki::Import

The Anki::Import documentation doesn’t make it clear enough, but using a quote(') works too for carrying on old tags along with the usual backtick, but for signalling an empty field only the backtick works.

Also I don’t think I can control the Cloze deletions - it automatically generates identifiers for them. Not going to get into perl to fix this :)

Vim regex reference

Vim Regular Expressions 101 is a really nice reference for vim’s search/replace/regex things. Maybe I’ll work through it later.

Most interesting is that groups are created with \(-\) and mentioned as \1 (will be handy for search-and-replace!)

I miss having a “now learning” textfile. (TODO)

Also this is a nice summary of the differences between vim and python/perl regexes, in vim characters are more likely to be literally interpreted: 1

Perl    Vim     Explanation
---------------------------
x?      x\=     Match 0 or 1 of x
x+      x\+     Match 1 or more of x
(xyz)   \(xyz\) Use brackets to group matches
x{n,m}  x\{n,m} Match n to m of x
x*?     x\{-}   Match 0 or 1 of x, non-greedy
x+?     x\{-1,} Match 1 or more of x, non-greedy
\b      \< \>   Word boundaries
$n      \n      Backreferences for previously grouped matches

And regex101.com remains the best place to test usual regexes.

Pinta and gthumb

I’ve been looking for something simpler than GIMP for casual blurring / cropping / adding text, pinta mostly fits the bill but I find it hard to use and no easy blur brush, gthumb is much more minimalistic in functions but is more pleasant to use.

Zsh global aliases and aliases that take arguments

Zsh has global aliases! An Introduction to the Z Shell - Aliasing is awesome. alias -g M='| more' -> who M

This has a lot of potential for often-typed parts of commands.

But I went there to look for arguments, and apparently zsh explicitly doesn’t have them and wants functions instead. So:

% rm () { mv $* /tmp/wastebasket }
% rm foo.dvi
% ls /tmp/wastebasket
foo.dvi

So I changed my taskwarrior s alias to:

#alias s='task s sprint.is:$SPRINT or sprint:c' 
s () {task s sprint.is:$SPRINT or sprint:c $*}

Now I can finally filter my tasks for the sprint (s +F)

// TODO replace dependence on $SPRINT by just usind current week number.

Not the first time I neglect to read the documentation of the software I switch to, being happy that it mostly works like the previous one.

The Technium: 68 Bits of Unsolicited Advice

My favourite parts:

  • Being enthusiastic is worth 25 IQ points.
  • Being able to listen well is a superpower. While listening to someone you love keep asking them “Is there more?”, until there is no more.
  • A worthy goal for a year is to learn enough about a subject so that you can’t believe how ignorant you were a year earlier.
  • Gratitude will unlock all other virtues and is something you can get better at.
  • Treating a person to a meal never fails, and is so easy to do. It’s powerful with old friends and a great way to make new friends.
  • Reading to your children regularly will bond you together and kickstart their imaginations.
  • Rule of 3 in conversation. To get to the real reason, ask a person to go deeper than what they just said. Then again, and once more. The third time’s answer is close to the truth.
    • Compare Five whys - Wikipedia* and death certificates with multiple “due to (or as a consequence of)”
  • The purpose of a habit is to remove that action from self-negotiation. You no longer expend energy deciding whether to do it. You just do it. Good habits can range from telling the truth, to flossing.
  • Promptness is a sign of respect.
  • If you are looking for something in your house, and you finally find it, when you’re done with it, don’t put it back where you found it. Put it back where you first looked for it.
  • Show up. Keep showing up. Somebody successful said: 99% of success is just showing up.
  • Separate the processes of creation from improving. You can’t write and edit, or sculpt and polish, or make and analyze at the same time. If you do, the editor stops the creator. While you invent, don’t select. While you sketch, don’t inspect. While you write the first draft, don’t reflect. At the start, the creator mind must be unleashed from judgement.
  • Perhaps the most counter-intuitive truth of the universe is that the more you give to others, the more you’ll get. Understanding this is the beginning of wisdom.
  • Friends are better than money. Almost anything money can do, friends can do better. In so many ways a friend with a boat is better than owning a boat.
  • You are what you do. Not what you say, not what you believe, not how you vote, but what you spend your time on.
  • When you die you take absolutely nothing with you except your reputation.
  • Before you are old, attend as many funerals as you can bear, and listen. Nobody talks about the departed’s achievements. The only thing people will remember is what kind of person you were while you were achieving.
  • When crisis and disaster strike, don’t waste them. No problems, no progress.
  • When you get an invitation to do something in the future, ask yourself: would you accept this if it was scheduled for tomorrow? Not too many promises will pass that immediacy filter.
  • Acquiring things will rarely bring you deep satisfaction. But acquiring experiences will.
  • Rule of 7 in research. You can find out anything if you are willing to go seven levels. If the first source you ask doesn’t know, ask them who you should ask next, and so on down the line. If you are willing to go to the 7th source, you’ll almost always get your answer.
  • When someone is nasty, rude, hateful, or mean with you, pretend they have a disease. That makes it easier to have empathy toward them which can soften the conflict.
  • Eliminating clutter makes room for your true treasures.
  • Experience is overrated. When hiring, hire for aptitude, train for skills. Most really amazing or great things are done by people doing them for the first time.
  • Buying tools: Start by buying the absolute cheapest tools you can find. Upgrade the ones you use a lot. If you wind up using some tool for a job, buy the very best you can afford.
  • Following your bliss is a recipe for paralysis if you don’t know what you are passionate about. A better motto for most youth is “master something, anything”. Through mastery of one thing, you can drift towards extensions of that mastery that bring you more joy, and eventually discover where your bliss is.
  • The universe is conspiring behind your back to make you a success. This will be much easier to do if you embrace this pronoia.

Mafia distributes food to Italy’s struggling residents

In recent days, the police in Naples have intensified their presence in the poorest quarters of the city, where men tied to the Camorra, the Neapolitan mafia, have organised home delivery of food parcels. Magistrates have already begun an investigation against a group of people who were questioned while distributing food to local residents.

Vim custom syntax highlighting

For SIOM and my morning pages the following two commands highlight in yellow all lines starting with a “+” after zero or more of any kind of space:

:syntax match mys /^\s*+.*$/
:highlight link mys Keyword

To do this everytime I open a markdown file:

fun! SetQuestions()
    syn match mys /^\s*+.*$/
    hi link mys Keyword
endfu
autocmd filetype markdown :call SetQuestions()

Python stalinsort testcases

Never thought about it like this, but for simple algorithms the test cases can be put in a nice array and iterated through: stalin-sort/test_utils.py at master · gustavo-depaula/stalin-sort

# pairs of input - output
test_cases = [([1, 2, 3, 4, 5], [1, 2, 3, 4, 5]), # sorted list
              ([5, 4, 3, 2, 1], [5]), # reversed list
              ]
# test sort_fun on all test cases defined above.
def test_all(sort_fun):
  for xs, expected in test_cases:
    print(f'testing with input {xs}, expecting output {expected}.')
    result = sort_fun(xs)
    print(f'output was {result}')
    assert(result == expected)

screen naming screens

Screens named with screen -S myname and attached by screen -r myname - tab completion works with screen -r!

Taskwarrior list unfinished tasks created more than 2 weeks ago

entry is the time the task was created. So:

task all sprint:$SPRINT status:pending entry.before:eow-3wk tags.not:s rc.report.all.columns:entry,end,tags,description rc.report.all.labels=Age,Done,Tags,Description rc.report.all.sort:end rc.verbose:label,blank is what I’ll use in SIOM.

  • t Today
  • g Go to date
  • c create

Tensorflow GPU use

If more than 1 GPU are visible, tensorflow will take some memory on all of them, even if its actively using only one. Restricting visibility the usual way helps.

How to make perfect italian pizza

This is a really nice video: How to Make Perfect Pizza | Gennaro Contaldo - YouTube

Qutebrowser mediawiki yank userscript

Using an userscript for this is overkill, but ``` #!/usr/bin/python3 import os title = os.environ['QUTE_TITLE'] url = os.environ['QUTE_URL'] with open(os.environ['QUTE_FIFO'], 'w') as f: f.write("yank inline \"[{} {}]\"".format(url, title)) ``` Located at `/home/shamotskyi/.local/share/qutebrowser/userscripts/yank_w.py`. In the config, `config.bind('yw', 'spawn --userscript yank_w.py')`

EDIT: replaced this with config.bind('yw', 'yank inline "[{url} {title}]"').

Taskwarrior tasks completed today

I have not been using it to the fullest.

List tasks completed today: task all status:completed end:today This might be something I can copypaste into my pages or in my reports, such as my weekly sprint review! Adding it as a module to siom should be not too hard. Taskwarrior - Usage Examples contains more nice examples.

Taskwarrior / zsh / … week number

For the sake of consistency (to each other and especially to Google Calendar) now my sprint number and week number is the ISO week number: export SPRINT=$(date +%-V)

Fixed this in:

  • $SPRINT environment variable
  • weekNumberValue in siom
  • i3 statusline:
    tztime local {
          format = "[%V] %a %Y-%m-%d %H:%M:%S"

Only place it’s left now is in my paper calendar, but I don’t use it too much these days.

Cooking

Pasta

Try adding cauliflower in my pasta water 1

And pasting my favourite Reddit comment for posterity:

[deleted] 385 points · 1 year ago · edited 1 year ago

This isn’t wrong, but not the tradition Italian way. The way we do it in Italy (Sicily) is to split the sauce in half. Take the pasta out about a minute or less before al dente. If you’re going for the creamy flavor, sauce permitting, mix some butter with the pasta as you’re draining the water. Then put the pasta in the sauce pan with half of the sauce and a (tiny) bit of pasta water. 1/4 of a cup is too much in our opinion because you don’t want to cook the pasta in the sauce for too long. Use the other half of the sauce to top it off. That’s not to say this is the only way Italians do it, but my Southern Italian family has been using this method for generations. I’m not a fan of OP’s method, if you want this kind of pasta just make a cacio e pepe.

On a separate but related note, tomato sauces (without meat) should only be cooked for 30 minutes, after that they lose the aroma. Of course I’m biased, but a simple tomato sauce is one of the easiest and most delicious things in the world to make. Simmer garlic until sizzling (add red pepper flakes with garlic for arrabbiata) add decent plum tomatoes (buy whole ones and hand crush them) with S&P, basil, oregano. You can add some butter if you like. Stir occasionally, 30 minutes later you’re done.

Edit: I always used to laugh to myself when I saw people getting excited about getting their first gold, and now I’m that person. Thanks kind stranger. 2

Bread

You can freeze bread without problems:

He starts with what not to freeze: “I never recommend freezing things like baguettes or ciabatta. Anything that has a large surface-to-crumb ratio just never refreshes the same.” 3

If baking, let your bread cool completely. This will prevent it from becoming soggy or moldy. Wrap each loaf tightly in plastic wrap. Then wrap it in foil or freezer paper. The double-wrap is your secret weapon for freshness.4

Unfreezing works overnight in the refrigerator. 4

While I’m at it, the yeast ratio is 2 1/4 teaspoons dry active, instant, or rapid-rise yeast granules (usually one 1/4-ounce packet) = 2/3 ounce fresh yeast 5

Keyboard layout changes

Made the following changes and bumped the version to v5:

Now I have brackets on my right hand letters :) I’ll think later what other symbols I still have not learned by heart and move the below. (Numbers, maybe?)

Python run from command line / shell with all the imports and stuff

Say I’m in folder2 and want to run folder2/folder/main.py

python3 -m folder.main adds folder2 to $PATH, while python3 folder/main.py adds folder to $PATH. The first option makes all imports much much easier.

Giving names to screen sessions

To set a name to a screen session to make attaching it easier, you either set it as parameter during screen creation (screen -S screenname) or set it from inside an attached screen by typing <C-a> :sessionname screenname. It will look like that:

There are several suitable screens on:
	74720.trying_to_run_GPU	(03/28/20 00:33:28)	(Attached)
	70666.whatisthis	(03/28/20 00:20:53)	(Detached)

(Setting a name for a screen session - Unix & Linux Stack Exchange)

To attach it I can use only its name: screen -raAd whatisthis

TODO actually read the man pages and have a better understanding of these flags instead of treating them like incantations.

watch command set interval and highlight changes

This is nice! To watch a file grow in size, except watch ls -lar you can do watch -d -n 1 ls -lar. -d makes it highlight the differences, and -n for some reason is the interval. (-i was taken I guess).

Use only one GPU for training in Tensorflow

I keep googling this, so: export CUDA_VISIBLE_DEVICES=2

And to set an environment variable before running the script (in bash at least) it’s TEST=foo; echo $TEST (shell - How do I set an environment variable on the command line and have it appear in commands? - Unix & Linux Stack Exchange). export is just to make it available for other commands.

Random

It’s quite cute how google interprets me looking for kitty paths linux as cat paths linux, as in I believe that they are kinda similar in many contexts.

That said, it’s very refreshing to see a program where reading the config file documentation on its official website doubles as basic tutorial for the program, since all the keyboard shortcuts used in the example config are the real ones.

Tensorboard & SSH tunnelling

Not sure why this surprises me, but I can first start a SSH shell that does a tunnel (.. and opens a SSH shell), then from it start the thing on the port that I am tunnelling. This almost looks like something I could automate if I do it often enough.

Qutebrowser writing python userscripts

Just wrote this and put it into ~/.local/share/qutebrowser/userscripts/yank.py.

This is an userscript that allows me to escape my only problematic markdown character (|) when copying with ym:

url = os.environ['QUTE_URL']

with open(os.environ['QUTE_FIFO'], 'w') as f:
    f.write("yank inline \"[{}]({})\"".format(title, url))

Why do color TVs make black and white snow? | Hacker News

The other question is “why don’t you see that noise when the TV is tuned in?” The TV has automatic gain control. When the signal is weak, it will amplify it up to the right level. If the signal is just background noise, then it will amplify that background noise until it’s at the “right level” for a proper TV signal. So, the gain is lower for stronger signals, and very high when there is no signal at all.

TL;DR move files, install manually my one extension needed, export/import mysql table data, point the wiki to the newly created table/db, run php maintenance/update.php and it just magically took care of everything. Only gotcha was that I forgot the db prefix, which gave me DBQueryError after restore; error in update.php on Project:Support desk, solved with the first google result. This was so much easier than expected.

EDIT2 - forgot about Extension:ParserFunctions - MediaWiki, and a couple of smaller ones. So:

# End of automatically generated settings.
# Add more configuration options below.

enableSemantics('pchr8.net');
wfLoadExtension( 'ParserFunctions' );

wfLoadExtension('CategoryTree');
$smwgShowFactbox=SMW_FACTBOX_NONEMPTY;
wfLoadExtension('NewestPages');

EDIT3: Had to move the /images/ folder with its content. To check for them, Gallery of new files - Fiamma works

Now live again at pchr8.net/f/

EDIT4: properties seem to be broken and capitalized, which makes semantic search unusable. I’ll deal with it later.

zsh setting and checking environment variables

If I do: export PYTHON_PATH=$(pwd), then check it via $PYTHON_PATH hoping to see something like:\ zsh: command not found: Fr 20. Mär 19:48:01 CET 2020 - this won’t happen, as this is a path, and the result would be same as cd $PYTHONPATH, therefore outputting nothing and leaving me with the impression that the value was not being set.


Day 444

Changed the font from Fira Code Light to Fira Code Medium (EDIT: now Bold. True-bold text still gets rendered as extra-bold, which is very nice too!). It works much better on not-bright-enough screens that stand in front of too-bright windows.

Tensorflow saving model weird errors about init things

I could not save a Tensorflow Keras model, the issue was that I passed arguments from init as: self.whatever = whatever, then changed self.whatever to a different data type (string to b’ytes’ w/ .encode in my case), then in the get_config() function then I happily said {'whatever': self.whatever,} which then could not be encode()‘d.

Day 443

Githubusing keys instead of passphrase

This is very nice and concise: Setup SSH keys for use with GitHub/GitLab/BitBucket etc, along with this series: Generating a new SSH key and adding it to the ssh-agent - GitHub Help

TL;DR generate a key, add it to Github, add it to the ssh-agent as

$ eval "$(ssh-agent -s)"
> Agent pid 59566
$ ssh-add ~/.ssh/id_rsa

Test the results as

→ ssh -T git@github.com                     
Hi username! You've successfully authenticated, but GitHub does not provide shell access.

If the key is in a non-default location, Host github.com HostName github.com User jaeaess IdentityFile ~/.ssh/id_rsa_github_jaeaess is needed in the ~/.ssh/config file.

To push without being asked for passwords, the remote needs to be changed from HTTPS to SSH:

$ git remote remove origin
$ git remote add origin git@github.com:AquilineAdaeze/gitformyMac.git

Since it doesn’t seem to be persistent, the unsafe way (even though it’s considered unsafe in general) is to add ssh-add -q ~/.ssh/id_rsa_github to startup.

Transformer Keras load a trained model and do some changes

Very interesting discussion: Loading a trained model, popping the last two layers, and then saving it · Issue #8772 · keras-team/keras

For the Sequential model, model.pop() also exists but not for the Functional one.

For a Functional model, after getting a model from an .h5 file, we can do things such as: new_model = Model(model.inputs, model.layers[-3].output)


Day 442

Keras / Tensorflow why saving a subclassed model is hard

Very nice R-centric explanation, but should be valid for Python too: Saving and serializing models

A subclassed model differs in that it’s not a data structure, it’s a piece of code. The architecture of the model is defined via the body of the call method. This means that the architecture of the model cannot be safely serialized. To load a model, you’ll need to have access to the code that created it (the code of the model subclass). Alternatively, you could be serializing this code as bytecode (e.g. via pickling), but that’s unsafe and generally not portable.

TODO Tensorflow model saving / prediction

Why am I getting wildly different accuracies and losses after loading the model from .h5 file, when model.weights for both are identical and predictions (using model.predict()) too? This probably has something to do with me misunderstanding datasets, how exactly?

Tensorflow Keras reset states of everything

Everytime I call model.fit() it does NOT reset the weights, DOES reset the hidden states (such as RNN/LSTM), does NOT reset optimizer settings. machine learning - keras.fit() re-initialises the weights - Stack Overflow

If I want to reset them, keras.backend.clear_session() should clear the info from the previous model.


Day 434

Matplotlib/pyplot reset styles

If I set a style like paper with plt.style.use('paper') it changes some settings (esp. in Jupyter Notebook) that don’t get overwritten by the next calls to plt.style.use(). For this, plt.style.use('default') exists. (Found here: python - How to recover matplotlib defaults after setting stylesheet - Stack Overflow)

Matplotlib have lines of the same colours when cycling / set line colour explicitly

Found here: python - How to set same color for markers and lines in a matplotlib plot loop? - Stack Overflow

The idea is to access the colour cycle directly:

    ax = plt.gca()
    color = next(ax._get_lines.prop_cycler)['color']
    plt.plot(x, y, linestyle='', markeredgecolor='none', marker=marker.next(), color=color)

Also I learned that there’s a nice way to get a value for ax when I don’t have it: ax=plt.gca() And that I should look into itertools because this is really neat (TODO: Look into itertools):

marker = itertools.cycle(('o', 'v', '^', '<', '>', 's', '8', 'p'))
marker=marker.next()

Matplotlib get list of available styles

The list of available styles in matplotlib: plt.style.available

To use: plt.style.use('paper')

Matplotlib adjust subplots

When creating a plot with many subplots via a loop I had the issue that they were too close together. Fixed with plt.subplots_adjust(): matplotlib.pyplot.subplots_adjust(left=None, bottom=None, right=None, top=None, wspace=None, hspace=None)`

Day 429

Python imports

Python ‘No module named’ error; ‘package’ is not a package - Stack Overflow TL;DR Beware of conflicting filenames.

I keep getting bitten by this - if I have a folder called something and inside it something called something.py and want to import something from the folder, it will take something to mean something.py instead of the folder.

Quoting the most helpful answer:

I was using the same name for both a sub-package (directory) and a module (file) within it.

For example I had this:

    /opt/mylib/myapi
    /opt/mylib/myapi/__init__.py
    /opt/mylib/myapi/myapi_creds.py        # gitignored file for user/pass
    /opt/mylib/myapi/myapi.py              # base module, load creds and connect
    /opt/mylib/myapi/myapi_dostuff.py      # call myapi.py and do work

The script ‘myapi.py’ imports credentials from myapi_creds.py via this statement:

    from myapi.myapi_creds import my_user, my_pass
 
Testing the module 'myapi.py' resulted in this error:
 
    $ ./myapi.py
    Traceback (most recent call last):
      File "./myapi.py", line 12, in <module>
        from myapi.myapi_creds import my_user, my_pass
      File "/opt/mylib/myapi/myapi.py", line 12, in <module>
        from myapi.myapi_creds import my_user, my_pass
    ModuleNotFoundError: No module named 'myapi.myapi_creds'; 'myapi' is not a package

The solution was to rename myapi.py to myapi_base.py so it’s name does not collide with the sub-package name.

General idea about Tensorflow and writing stuff for it

It’d be nice to have fixed values (and especially dimensions!) for my tensors that I use for testing stuff such as layers. If my input tensors’ dimensions are predictable, like [10, 9, 8, ...] for each dimension, I’d be able to recognize them immediately at various stages without having to think about it. For a level up, I can consider for example Fibonacci numbers or similar, that have different divisors, so that the program will fail early and predictably if I do something wrong.

Otherwise I kinda like the approach of Tensor Considered Harmful, especially the part where dimensions have human-readable names.

Intellij idea “Add as content source” getting ignored that leads to “module not found” in Python depending on the order of the files of $PYTHONPATH and/or sys.path

Right click → Unload modules helped; I could unload the conflicting module, after this it happily started importing the files from the second source root. This is a band-aid fix but for now it works; TODO later find out a better way to solve these problems.

If not, there are always uglier hacks like sys.path.extend(['folder_marked_as_source_root_that_doesn't_seem_to_get_added_to_$PATH'])

For details, cursor movement - How do I jump to the location of my last edit? - Vi and Vim Stack Exchange.

From the first answer:

The \`. command will bring you to your last change.

The \` goes to a mark, and . is a “special” mark which is automatically set to the position where the last change was made. See :help `. for some more information.

There is also `` which will bring you back to where the cursor was before you made your last jump. See :help \`\` for more information.

Another useful mark is \`^; this is the position where the cursor was the last time when insert mode was stopped. See :help \`^.

CNN tutorial

Again I come back to this nice resource: 6.4. Multiple Input and Output Channels — Dive into Deep Learning 0.7.1 documentation

It has a very nice explanation of CNNs and in/out channels and stuff.

Especially output channels:

Regardless of the number of input channels, so far we always ended up with one output channel. However, as we discussed earlier, it turns out to be essential to have multiple channels at each layer. In the most popular neural network architectures, we actually increase the channel dimension as we go higher up in the neural network, typically downsampling to trade off spatial resolution for greater channel depth. Intuitively, you could think of each channel as responding to some different set of features\o(6.4. Multiple Input and Output Channels — Dive into Deep Learning 0.7.1 documentation)

It has sisters such as tf.math.less, etc.

Tensorflow python unittests check for equality of two tensors

tf.assertEqual(x, y) exists, can be used in unittests as is, if it raises an error the test automatically fails.

Intellij idea generate tests

This is awesome! Right click on class name -> Generate -> Test, and this creates a boilerplate file with the right name and right methods.

Python truthy and falsy

TIL that values considered true/false without being explicitly True/False have a name, and from python - What is Truthy and Falsy? How is it different from True and False? - Stack Overflow here’s a handy list of them:

All values are considered “truthy” except for the following, which are “falsy”:

  • None
  • False
  • 0
  • 0.0
  • 0j
  • Decimal(0)
  • Fraction(0, 1)
  • [] - an empty list
  • {} - an empty dict
  • () - an empty tuple
  • '' - an empty str
  • b'' - an empty bytes
  • set() - an empty set
  • an empty range, like range(0)
  • objects for which
    • obj.__bool__() returns False
    • obj.__len__() returns 0

A “truthy” value will satisfy the check performed by if or while statements. We use “truthy” and “falsy” to differentiate from the bool values True and False.

Python type hinting

Allegedly one of the best tutorials to start with: Type hinting and annotations — Python for you and me 0.4.alpha1 documentation, link found here: A deep dive on Python type hints · Vicki Boykis. That blog in general is quite interesting, she’s the same person who wrote IT runs on Java 8 · Vicki Boykis.

Tensorflow py_function in mapping and Raggedtensors

    one, two= tf.py_function(func = py_mix, inp=[one, two],  Tout = (tf.int32, tf.int32))

one is a RaggedTensor. This gives an error:

TypeError: Tensors in list passed to 'input' of 'EagerPyFunc' Op have types [<NOT CONVERTIBLE TO TENSOR>, int32] that are invalid. Tensors: [tf.RaggedTensor(values=Tensor("RaggedFromVariant/RaggedTensorFromVariant:1", shape=(None,), dtype=int32), row_splits=Tensor("RaggedFromVariant/RaggedTensorFromVariant:0", shape=(None,), dtype=int64)), <tf.Tensor 'RaggedFromVariant_1/RaggedTensorFromVariant:0' shape=(None,) dtype=int32>]

one.to_tensor() converts it to Tensor and this works.

Additionally, if I set Tout to be only one value, I get a nice descriptive error: OperatorNotAllowedInGraphError: iterating over tf.Tensor is not allowed: AutoGraph is disabled in this function. Try decorating it directly with @tf.function.

Giving a type for both outputs fixes this.

Tensorflow RaggedTensor and Tensor evaluation

Ragged tensors  |  TensorFlow Core gives a nice breakdown of the ways to evaluate a Tensor in general:

  • print(rt.to_list())
  • print(rt[1].numpy())
  • Printing the constutuents of it:
    • print(rt.values)
    • print(rt.row_splits)

Intermezzo - 2

Три истории про Мерзебург

Вот про Мерзебург надо писать на русском языке, на самом деле, хотя нереально объяснить почему.

Сижу за идеально пустым столом комнатки где провел предыдущие 4 года. Вокруг какие-то непонятные бумаги на полу, какие-то ручки, как будто после урагана.

Now playing: Stravinsky - Le sacre du printemps / The Rite of Spring

Господи, сколько же всякого происходило тут за последние 4 года.

Сижу за знакомым столом, который на идеальной высоте, куда идеально ложатся локти. Хотя все вещи кроме общажной мебели отсюда увезены, чудом осталась свечка и спички. Сейчас она горит и пахнет воском, тоже до боли знакомый запах, с точностью до всех нот - конкретно такие свечки и покупал 4 года подряд. И писал на таких листочках А4, тем же почерком, той же рукой.

Candle.

Свеча выглядит как будто она догорит сегодня, и это лучшее и самое правильное совпадение этого мира.

Комнатка прошла полный круг - а изменился ли я?

А еще - город где была сфокусирована моя жизнь довольно долгое время. Сейчас тут пустая комната, за окном - темнота, хорошие люди в городе и самом общежитии в общем-то остались, но само нахождение тут как-то просто странно. Очень хороший повод порефлексировать о том, как можно себя чувствовать совершенно чужим в каком-то городе, особенно по вечерам. Помню летние месяцы тут - за окном лето, ты в напрочь пустом общежитии маленького городка восточной Германии, чувство свободы и пустоты, лето, бесконечное лето, лето как состояние. С работой это все будет стираться, и надо пытаться себя учить замечать маленькие детали в изменениях сезонов, иметь хоть какие-то ритуалы связанные с разными порами года, чтоб это не сливалось и чувствовать, к приеру, лето, про-живать, пере-живать сезоны. Постик об этом, отчасти.

Но это все лирика, лирика которая не должна отвлекать нас от того, что на самом деле важно -

Инсмут

Тут еще будет уместен этот линк на пост, написанный когда я только-только приехал сюда: Файне місто Мерзбург | Я сам, соломка, чай.

Сложно написать что-то общее про Мерзебург и мое отношение к нему. Если бы писал, то “блеск и нищета” точно бы звучало. Чем-то очень темный город, маленький, по-своему в некотором роде некоторым образом уютный, без лишних претензий. Но все же, темный, давящий, причем давящий с самого начала. Все хорошее, что я мог про него говорить, было скорее стокгольмским синдромом и рационализацией.

Если город маленький, общение с людьми приобретает чуть больше граней. И общение с городом-вообще, где ты знаешь в лицо всех кассирш ближайшего магазина, единственного филиала банка, где четыре года подряд ходишь в одну аптеку и тебя там узнают, и ты узнаешь всех (двух) людей, которых ты там когда-либо видел за прилавком.

Как будто личности, которые часть этого города, имеют более прочную позицию в нем, имеют чуть большее значение. Ты встречаешь дедушку на лавочке, болтаешь с ним - дедушка важен, лавочка важна, озеро, около которого она, тоже важно. Ты не анонимен и лавочка не анонимна. Все имеет больший масштаб и связь между всем сильнее.

Вне этого - если что-то тебя давит, то город беспощаден, и тебе в нем не затеряться и не отвлечься. Сенека что-то писал про то, что постоянные переезды и путешествия – признак беспокойного духа. Мне кажется надо иметь нереально спокойный дух, чтоб мочь долго жить в маленьком городке.

Не Инсмут

А если иметь спокойный дух - условия в принципе идеальные. Маленький универсистет, университет в 50 метров от общежития. 200 метров дальше - спортивный комплекс. Там можно играть в теннис с людьми, которых туда приглашаешь. По дороге туда встречаешь всех. А в тренажерном зале встречаешь местами преподавательницу немецкого языка, местами - ректора, который стоит и ждет своей очереди на тренажер у тебя над душой, что очень неловко всем.

Мерзе это город где к тебе могут просто зайти и пригласить выйти погулять, и ты идешь и просто гуляешь по территории и по Tiergarten, до которого метров 500. Это город где шикарно гуляется ночью. И шикарно разговаривается ночью.

Это город, в котором нереально хорошо видны звезды, все, и ночью можно ходить на них смотреть в кукурузные поля (до которых метров 700). Где есть крыша, на которую можно залазить и оттуда смотреть на затмение.

Это город где ты идешь в магазин за едой и это интересно, и это развлекаловка, и ты резко понимаешь в чем может быть прелесть шоппинга.

Мерзе меня многому научил. От того, как это, когда вокруг у тебя Мерзебург, где мало что происходит, а ты хочешь чего-то интересного - и ты учишься to make your own fun и организовываешь вещи.

Эти 4 год атут были мне очень необходимыми и уместными, продлились ровно столько, сколько нужно, и закончились в идеальное для этого время.

В эти секунды тушится свечка.

Спасибо тебе, свечка, спасибо тебе, столик.

Спасибо тебе, здание 5B.

Спасибо тебе, Мерзебург, спасибо за все.

Number bases in bash

bash - Value too great for base (error token is “08”) - Stack Overflow – tl dr bash/zsh see “018” as an octal number because it starts with 0. To fix this, we explicitly set the number base: 10#$varname.

Semantic highlighting

This is actually really nice as idea, and as usual someone on the internet thought about this more than I did: Making Semantic Highlighting Useful - Brian Will - Medium

I somehow really like the idea of having color giving me actual semantic information about the thing I’m reading, and there are a lot of potentially cool stuffs that can be done, such as datatypes etc. It’s very connected to my old idea of creating a writing system that uses color to better and more concisely mark different letters, like the apparently defunct Dotsies but even more interesting.

Taskwarrior end of year sprint renaming

The usual yearly ritual:

for o in $(seq 52) 
do
t sprint.is:$o modify sprint:2019-$o rc.bulk=0
done

Here a couple of things are interesting. Firstly, sprint.is:$o means basically sprint==$o. In cases where sprint==2, this helps against catching stuff life sprint==20 in the filter.

rc.bulk=0 is an override of the setting bulk which decides how many changes at the same time is too many. Regardless of the value of the confirmation setting. Here I set it to infinity, and this way I don’t get one question for each sprint.

Also Setting Up Multiple Project Areas with Taskwarrior – Steve Dondley is quite interesting – I’ll do something similar for work and home, except that I’ll use the existing t/tw aliases instead switching it like he does. But I might consider something like this so that t at work gives me the work tasks and my home tasks at home.

cp copy to target directory by overwriting the contents

linux - How to force ‘cp’ to overwrite directory instead of creating another one inside? - Stack Overflow

-T, --no-target-directory treats target as a normal file, not a directory. -v is also quite handy.

Lastly, I’m not sure how does taskwarrior work. When I try to delete ~/.task it gets recreated with the standard files, but empty ones, as if it was a clean taskwarrior install. I don’t see any task-like processes running. I’m not sure how is this possible.

Tensorflow documentation

tf.assign_add - TensorFlow Python - W3cubDocs - is this another place to read readable TF documentation?

Tensorflow eager execution – again; this time with Intellij idea breakpoints

model.run_eagerly=True is not enough – when creating a custom Metric, as mentioned in metrics.py, tf.config.experimental_run_functions_eagerly(True) is also needed.

As added bonus - if this is not enabled, Intellij Idea debugging also doesn’t work. As in the breakpoints get ignored.

Attribute modifiers make filters more precise.  Supported modifiers are:

  Modifiers         Example            Equivalent           Meaning
  ----------------  -----------------  -------------------  -------------------------
                    due:today          due = today          Fuzzy match
  not               due.not:today      due != today         Fuzzy non-match
  before, below     due.before:today   due < tomorrow       Exact date comparison
  after, above      due.after:today    due > tomorrow       Exact date comparison
  none              project.none:      project == ''        Empty

  has, contains     desc.has:Hello     desc ~ Hello         Pattern match
  hasnt,            desc.hasnt:Hello   desc !~ Hello        Pattern non-match
  startswith, left  desc.left:Hel      desc ~ '^Hel'        Beginning match
  endswith, right   desc.right:llo     desc ~ 'llo$'        End match

  noword            desc.noword:Hello  desc !~ '\bHello\b'  Boundaried word non-match

Intellij idea

In intellij idea you can set more options for each breakpoint after right-clicking on it; especially “disable until breakpoint X is hit”, where X can be disabled.

Keras2 eager execution

.. is not there by default all the time; the hard-to-find answer for this is adding model.run_eagerly=True after model.compile().

Tensorflow / python Dataset iterator

Of course, the following also works:

[x[1][1]['mycast'] for x in dataset.enumerate(5).__iter__()]

Tensorflow padding

… add what you tell it to add, even if you’ve use tf.one_hot() on the data before. Then you get weird zeros in the result of the one hot encoding.

Day 323

Tensorflow gradient propagation

  • ValueError: No gradients provided for any variable in Tensorflow - Stack Overflow

    When you do annotation_pred = tf.to_float(tf.argmax(out, dimension=4, name='prediction')), you get an index of the max value in your tensor. This index can’t be derivated, thus the gradient can’t flow throught this operation.

    So as your loss is only defined by this value, and the gradient can’t flow throught it, no gradient can be calculated for your network.

Argmax is okay if I don’t calculate my loss through it.

Python / Numpy ellipsis (…)

  • Cookbook/Indexing - SciPy wiki dump

    The ellipsis (three dots) indicates “as many ‘:’ as needed” This makes it easy to manipulate only one dimension of an array, letting numpy do array-wise operations over the “unwanted” dimensions. You can only really have one ellipsis in any given indexing expression, or else the expression would be ambiguous about how many ‘:’ should be put in each.

ML/Tensorflow logits meaning

Logits are the inputs to the softmax function:

the vector of raw (non-normalized) predictions that a classification model generates, which is ordinarily then passed to a normalization function. If the model is solving a multi-class classification problem, logits typically become an input to the softmax function. The softmax function then generates a vector of (normalized) probabilities with one value for each possible class.

ML attention animated

After all this time, I found this excellent animated example of attention and transformer and RNNs: Visualizing A Neural Machine Translation Model (Mechanics of Seq2seq Models With Attention) – Jay Alammar – Visualizing machine learning one concept at a time. From the same source, A Visual Intro to NumPy and Data Representation – Jay Alammar – Visualizing machine learning one concept at a time look very nice. I should resurrect my link wiki instead of pasting it all here.

Coding fonts

Python

Interesting python syntax

Interesting Python syntax I’ve seen in the Transformer Google repo:

  • /= assignment operator, which is like +=.
  • X if Cond else Y:
stats = ({
        "loss": train_loss
    } if history is None else misc.build_stats(history, callbacks))
  • Can be also used in returns:
    return evaluate_and_log_bleu(
        self.predict_model, self.params, self.flags_obj.bleu_source,
        self.flags_obj.bleu_ref, self.flags_obj.vocab_file,
        self.distribution_strategy if self.use_tpu else None)

Kinda relevant is code golf - Tips for golfing in Python - Code Golf Stack Exchange.

Python rich comparison operators

object.__lt__(self, other)
object.__le__(self, other)
object.__eq__(self, other)
object.__ne__(self, other)
object.__gt__(self, other)
object.__ge__(self, other)
  • The correspondence between operator symbols and method names is as follows: x<y calls x.lt(y), x<=y calls x.le(y), x==y calls x.eq(y), x!=y calls x.ne(y), x>y calls x.gt(y), and x>=y calls x.ge(y).

Stack

I should really create a vim thingy that automatically creates footnotes from a link. I can imagine it as a keystroke which generates a random footnote name and puts you on the last line of the file, with the footnote name prefilled, and in insert mode. Or another one that lets you specify a footnote name.


Day 296

apt-get purge and zsh

zsh does its own wildcard stuff, and apt-get purge nvidia* doesn’t work because of this. apt-get purge nvidia\* does (or with ‘’s). Same story as with scp, I’m surprised I keep having issues with this.

Linux see history of apt-get

Linux z-commands (zcat, zless, zgrep, zdiff)

  • Paradigm = [pa ruh daim] or American [peh ruh daim]

Linear algebra

I’ll be following this: 9.1. Attention Mechanism — Dive into Deep Learning 0.7 documentation

  • Inner product is the generalization of the dot product. Result is a scalar. 1

Python assert statement

UsingAssertionsEffectively - Python Wiki assert condition, message -> if condition is false, it returns an AssertionError.


Day 281

ML

Most of this while I’m reading the “Attention is all you need” paper. The most important resources will be The Illustrated Transformer – Jay Alammar – Visualizing machine learning one concept at a time and 9.3. Transformer — Dive into Deep Learning 0.7 documentation.

Definitions

  • BLEU is a metric of how good machine translation is.
  • Gentle Introduction to Transduction in Machine Learning

  • Positional encoding in the Transformer is very well described at 9.3. Transformer — Dive into Deep Learning 0.7 documentation, with a visualization. Needed because there is no notion of the order of words in the architecture 1 We can’t do n=1..10 because sentences have different lengths, and word 3 out of 10 is not the same as 3 out of 3.
    • “The intuition here is that adding these values to the embeddings provides meaningful distances between the embedding vectors once they’re projected into Q/K/V vectors and during dot-product attention” 2
  • Subword algorithms are ways to represent words that use elements bigger than characters but lower than a word embedding, for example prefixes and suffixes, to better handle unseen words. Byte-pair and word-piece encodings are used by the Transformer.[^swa]
  • In essence, label smoothing will help your model to train around mislabeled data and consequently improve its robustness and performance. 3

Day 280

Pyplot / matplotlib creating multiple subplots

Creating multiple subplots using plt.subplot — Matplotlib 3.1.0 documentation

fig, (ax1, ax2) = plt.subplots(2)
fig.suptitle('Vertically stacked subplots')
ax1.plot(x, y)
ax2.plot(x, -y)

(or fig, (ax1, ax2) = plt.subplots(1, 2) if we want them side by side)

Pandas groupby plot without index

pandas.core.groupby.DataFrameGroupBy.plot — pandas 0.16.2 documentation has use_index, which decides if the values will be graphed using index as x (side-by-side) or one on top of the other.


Day 277

Python redirect stdout/output to file

This is really really neat!

def redirect_to_file(text):
    original = sys.stdout
    sys.stdout = open('/path/to/redirect.txt', 'w')
    print('This is your redirected text:')
    print(text)
    sys.stdout = original
 
    print('This string goes to stdout, NOT the file!')

(from Python 101: Redirecting stdout - The Mouse Vs. The Python)


Day 273

Unpack Java jars

Apparently java files are archives! Laut Extracting the Contents of a JAR File (The Java™ Tutorials > Deployment > Packaging Programs in JAR Files) it’s jar xf jar-file [archived-file(s) to extract].

Pandas and numpy have different std/stdev standard deviation functions!

Both are correct, one divides by N, the other by N-1.

t df.std()==np.std(df, ddof=1). Somethingsomething delta degrees of freedom. ddof=0 can also be passed to pandas.


Day 271

Jekyll hide page from navigation

Out of all the ways I’ve found and described here, this is so far the cleanest one.

title: Some Title
layout: default
exclude: true

and then

 {% unless page.exclude %}
        <a class="page-link" href="{{ page.url | prepend: site.baseurl }}">
            {{ page.title }}
        </a>
    {% endunless %}

Day 268

Work/play balance in i3 statusbar

Every productivity thought I’ve ever had, as concisely as possible - Alexey Guzey has been extremely inspiring. I added “work/play” to my statusbar, just for fun, with the following code to the statusbar wrapper script:

bashCommand2 = "date +%R" #returns %H:%M in 24h-format
bashOutput2 = subprocess.check_output(['bash','-c', bashCommand2]).decode('utf-8').strip('\n')
time=bashOutput2.split(":")
hour=int(time[0])
minute=int(time[1])

if hour in {9, 12, 15, 18, 21}:
    if minute>5 and minute<35:
        wp="P"
    else:
        wp="W"
else:
    if minute<5 or (minute>30 and minute<35):
        wp="P"
    else:
        wp="W"

j.insert(0, {'full_text' : '%s' % wp, 'name' : 'wp'})

TODO – py3status

Stumbled upon Modules — py3status 3.20 documentation, and this looks like a much better alternative to the above. I’d need to move the python script in a separate file and that’s okay, everything else is absolutely wonderful.


Day 266

Intermezzo

Had a long and wonderful vacation, and as it usually happens – I regret not keeping better records of what happened. In general, I feel like I’m losing some touch with my ability to write and to do at least semi-artistic things – and I believe this to be a great loss (for me, not for humanity).

Now playing: Музыка для никого - Агата Кристи (минус на пианино). Currently in the plane and without a connection, so untypically there will be no links.


During this trip home we organized another “we have a projector, make a ~20min presentation about whatever interests you” thing, and it went even better than the first – it’s not hard to get people to talk about stuff they are interested in. And it’s a wonderful way to get exposed to a lot of awesome stuff you didn’t know existed – topics ranged from vaccinations to roleplaying to how to play a flute.

Then I took part in my first D&D game, and it was interesting. Not going to get into it heavily, but it’s fascinating how everything is organized to be playable, and I think I see the appeal of it all. Also it looks 10/10 like something I would love – I’m not really sure why I don’t.

The month leading to it were probably one of the least pleasant of the last couple of years – thesis, very unpleasant uni stuff, a couple of all-nighters I could not properly recover from. My coscience was about as fragmented and stressed-out and burned-out as it gets, I think. So after 3 days at home the best thing happened:

Then I went to a 2 week camping thing in the Karpathians.

Now playing: Летов - все идет по плану

И взагалі мій куточок в Інтернет, маю право на що завгодно – продовження буде українською.

Так от, похід по Карпатах – це було настільки тотальне очищення дуже фрагментованої свідомості. Він був значно ващим ніж заплановано, і днів шість (а заплановано було три дні) треба було просто йти вперед. Навіть по-людськи не було часу годинку відпочити і понасолоджуватися на привалі. Плюс було трошки складно з маршрутом, один траверс який був набагато гірше маркованим у середині ніж його початок збив з дороги десь на день. І рюкзаки були значно важчі ніж було б правильно. І вилилось це все в просто 6 днів нервів але особливо тупо фізичного навантаження. І насправді це те, що, думаю, було особисто мені потрібно.

Now playing: Давайте делать паузы в словах

А, ще були гори, багато гір. Дивишся назад - бачиш прекрасний вид. Проходить 40 хв, знову дивишся - він став ще прекраснішим. І ти бачиш гори-гори-гори яких не бачив раніше. І розумієш, що це саме ти своїми ногами піднявся на цю висоту.

Але чи не основне те, що дав цей похід - це Н днів майже без телефону і без Інтернет у будь-якому вигляді. І найбільшу очистку дало саме це. (Окрема галочка – місця без телефонного звʼязку. Коли ти десь на горі, не бачив ніяких зустрічних туристів дня два, розумієш, що до найближчого місця де зможеш подзвонити йти годин 6.) І відчуваєш тоальну свободу, словами не передати яку. Свобода-пустота-ямогувсе, розумієш що для щастя тобі - конкретно тобі - треба небагато. Що проблеми - це шукати дрова, щоб не змерзнути. Прості древні проблеми. Розумієш, скільки умовностей і абстракцій ти собі постворював в т.н. “реальному” житті, і наскільки те, що відбувається тут з тобою на декілька порядків реальніше.

Відчуваю, що гублю ці увідомленя – навіть зараз, пару тижнів після кінця походу. І це теж у мене було - це все про свободу і т.п. не просвітлення після якого все інакше (я не впевнений, що взагалі вірю у такі просвітлення). Такі усвідомлення треба поновлювати, і речі/події які дають такого плану речі теж потрібно повторювати. Пригадую, що було у собору в Кьольні, що було коло Синевиру, що було під час минулих поїздок автостопом. Записувати це може трошки нагадати, але не дасть той самий afterglow котрий на шкірі і глибший за свідомість.

Now playing: Команда нашего двора - Визбор

Не останнім фактором, мені здається, там була тема чисто фізичних зусиль. Коли ти робиш 140% від того, на що (думаєш) здатен. Доходиш на вершину гори. Бачиш просто вау вид навколо, навіть не робиш спробу сфоткати - все рівно нічого не передати, і чимось це вже порожні для тебе категорії. Максимально стараєшся відчути, про-жити це. В тілі всі ті характерні ендорфіни від фізичної роботи, яка так очищає душу.

А на дворі 12 ранку, і ти розумієш, що тобі ще 2 таких подвига сьогодні. Звʼязку немає і не буде, телефон вимкнений, десь у тебе тренується якась нейромережа, але це так далеко і чимось не-реально. Згадуєш людей з твого реального життя, обличча ніби як зі сну.

І ще важливим було чітке розуміння того, що тобі навіть в чисто фізичному плані не так багато потрібно - в плані їжі, 39 душів в день, чистої голови. І хоча все рівно буду її мити, розуміння що 6 днів підряд можна цього не робити і все буде ОК теж робило все світлішим і простішим, чи що. Типу постворювали собі абстрактні системи і умовності, живемо в цьому гіперреальному світі, вирішуємо проблеми в рамках цієї системи - а так не завжди було і можна інакше. (Не в плані, що це погано, але швидше, що цікаво це бачити – бо контакт з простим і реальним втрачаєш тим більше, чим більше часу не маєш контакту з простим і реальним).

Now playing: Ostatnia prośba wędrownego grajka (та сама “Переведіть мене через майдан” польською).

Коли дійшли до цивілізації ми були раді бачити цивілізацію, все ж.

І друга частина відпочинку була ідеальною – лежали в кроватці, гарно їли у місцевій колибі, ходили до озера, потім поверталися, ad infinitum. Але телефона все одно не сильно включали. (Пригадую наскільки фізично дивно було друкувати щось на телефонній клавіатурі). В перший вечір зʼїли 10 блюд з колиби на двох.

Баноші, деруни з былими грибами, млинці з ягодами, ось це все.

I весь другий тиждень був тотальний-тотальний відпочинок, і фізичний і когнітивний. І цей формат дуже спрацював - і я його використовуватиму у майбутньому. Можливо, зі значно простішим походом, де на тебе не давить необхідність щось робити щосекунди, а просто релакс без телефона, з гамаками, вогнищем, і т.п.

У будь-якому випадку, Київ був гарним і я був дуже радим його бачити.

Повернувся додому, все було нормально. Галочка 1 - фраза “З дороги завжли треба помити руки і вмитися, щоб змити з себе пил і погляди людей”, і фраза друга-єврея одного street performer про те, що “людей нужно удивлять”.


Позже, вероятно, последует похожий постикак о планах на следующий год.

Day 252


Day 232

Bash kill running shell script

The %% tells the bash built-in kill that you want to send a signal (SIGTERM by default) to the most recently suspended background job in the current shell, not to a process-id.


Day 228

Markdown tables widths


Day 226

Day 224

scikit-learn vectorizer passing tokens


Day 219

Asciiquarium as screensaver with alock

Tensorflow variable scopes

The goal of variable scopes is to allow for modularization of subsets of parameters, such as those belonging to layers (e.g. when architecture of a layer is repeated, the same names can be used within each layer scope).

Random


Day 214

Pandas remove duplicates efficiently (using only a subset of columns)

d.drop_duplicates(subset=['text'])

Markdown strikethrough uses two tildes

For this, markdown uses two tildes (like this).

(Should I write headers for these posts in /r/savedyouaclick style?)


Day 212

Delete files older than X days/hours via linux find

Also relevant is mtime, ctime, and atime - modification time, change time, access time.

mtime changes when you write to the file. It is the age of the data in the file. Whenever mtime changes, so does ctime. But ctime changes a few extra times. For example, it will change if you change the owner or the permissions on the file.

Tensorflow disable verbose logging; set environment variables before running script in Linux

TF_CPP_MIN_LOG_LEVEL=3 python3 tensors.py does the magic needed

Qutebrowser open in new tab

Inserted the following in config.py: config.bind('a', 'set-cmd-text -s :open -t'), to make a an alias for O

Linux find parents of a process

This is really really neat when running shell scripts that run other shell scripts etc. ps fax gives a nice tree. Can be combined with other stuff, so ps faux also works. TODO actually read through the man pages about this.


Day 211

Python – how to run a Python script inside live shell

Or, from the same SO thread, one can do just import filename_without_extension, even if it doesn’t follow the structure with main() etc., in my experience.

Tensorflow

Indexing and slicing multi-dimensional arrays or tensors in pandas, numpy, Tensorflo

This is probably one of the most SEO titles I’ve ever created, but I think it applies to all of them.

Tensorflow add one dimension (expand dims, expand_dims)

# 't' is a tensor of shape [2]
tf.shape(tf.expand_dims(t, 0))  # [1, 2]
tf.shape(tf.expand_dims(t, 1))  # [2, 1]
tf.shape(tf.expand_dims(t, -1))  # [2, 1]

Day 210

Linux screen scrolling


Day 204

Linux cal calendar alias

Finally cal is cal -m -w, which gives me Monday as starting date and shows the week numbers.

Week review pages script

Now names files after the week number, not the date.

FILE=./Week/$(date +%-U).markdown
DATE=$(date +%Y-%m-%d\ %H:%M:%S\ +0100)

“Clear screen and run command” zsh/bash alias

alias c="clear"
alias cc="clear; "

c remains, cc now clears the screen before next command is run. I noticed I’ve been doing this manually quite often, especially for todo stuff. Now cc s puts the output of s on the top of the terminal.

Wild random idea – since perspective on my screen, especially at the bottom of my screen, bothers me so much, could one make an eye-tracking thingy, calculate how much the screen output should be changed on x and y, and automatically do this, so that visually it looks like all the aspect ratios are preserved? Not sure how hard is this to implement, but either way I’m not touching this.


Day 198

Recording audio from speakers

This answer: sound - How to record output to speakers? - Ask Ubuntu mentions “Sound recorder”, and it works very well. Has weird settings about staying on top, running on startup etc that have to be changed.

9fb017224a344dc5f028b5a6b8000a8afb30f6fb


Day 197

Bash scripting

Increment variable in bash an math in general

How to increment a variable in bash? - Ask Ubuntu var=$((var + 1)) is the most portable one.

Redirecting stdout and stderr in bash

some_command >file.log 2>&1 is the only one that works for me in all cases. (shell - Redirect stderr and stdout in Bash - Stack Overflow)

Bash arbitrary number of arguments and their number

"$@" are the arguments one can iterate through, and "@#" is their number.


Day 196

Set up vim keybindings in bash/zsh/… via inputrc

Use vi shortcuts in terminal | Vim Tips Wiki | FANDOM powered by Wikia – add

set editing-mode vi
set keymap vi-command

to ~/.inputrc or /etc/inputrc and restart terminal.


Day 193

zsh history

I can use !2332-style stuff inside commands as I type them! mycommand !23 if !23 is test would run as mycommand test.

IPFS (Interplanetary Filesystem)

IPFS is the Distributed Web – it looks very interesting, I should read the whitepaper or some basic intro (A Beginner’s Guide to IPFS – HackerNoon.com)


Day 192

zip add to zipfile while ignoring directories

zip -j fileone filetwo ~/home/me/some/directory/file myzipfile.zip. -j means “junk directory structure”


Day 191

Qutebrowser focus tab N keybindings

Now number keys focus tabs, as I had on Firefox:

Also found this really nice config file: maxx/dotfiles - .config/qutebrowser/config.py at c6611e7ef3ab93a712b8e37e784fed1b38fc1174 - Gitea: Git with a cup of tea

Tensorflow shapes [], [None], None or ()

() and [] are equivalent.

placeholder with [] shape takes a single scalar value directly. Placeholder with [None] shape takes a 1-dimensional array and placeholder with None shape can take in any value while computation takes place. (tensorflow - What is the difference between [], [None], None and () for the shape of a placeholder? - Stack Overflow)

Linux

less for continuous data

Except the command line flag I always forget for tail (tail -f some.log), less can do the same. After opening a file, pressing F/<Shift-f> puts you in the end and automatically updates if the file changes.

tee

tee writes the output to a file while simultaneously showing it onscreen. Example from Linux tee Command Explained for Beginners (6 Examples) is ping google.com | tee output.txt

scp to a non-standard port

scp -P 1337 from to:folder, it uses a capital P.


Day 186

Tensorflow

tf.squeeze to remove dimensions of [1]

If I had a tensor of dimension [1, 2, 3], tf.squeze() would turn it into [2, 3]. tf.squeeze  |  TensorFlow Core r1.14  |  TensorFlow.

It removes any dimensions of shape 1 it finds. If I provide an axis parameter, it will only look at that dimension.

Day 178

Vim

Vim resize splits / vsplits

For a split window: You can use Ctrl-w + and Ctrl-w - to resize the height of the current window by a single row. For a vsplit window: You can use Ctrl-w > and Ctrl-w < to resize the width of the current window by a single column. Additionally, these key combinations accept a count prefix so that you can change the window size in larger steps. [e.g. Ctrl-w 10 +] (Resize splits more quickly | Vim Tips Wiki | FANDOM powered by Wikia)

Day 177

Python

Getopt

15.6. getopt — C-style parser for command line options — Python 2.7.16 documentation, especially the part optlist, args = getopt.getopt(args, 'abc:d:') – the options with a colon following need to have a value. Otherwise GetOptError will be raised.

Pandas Counter

Counter is much faster than count() in cases when you need to count multiple objects – you don’t have to iterate once for each object.

Jupyter notebook tqdm

Use from tqdm import tqdm_notebook as tqdm instead of usual vanilla tqdm.

Vim

vimdiff

vimdiff file1 file2 opens a nice vim session with two buffers. [c and ]c jump back and forward between changes. (See http://vimcasts.org/episodes/comparing-buffers-with-vimdiff/)

Switch splits’ position in vim

<C-w> <C-r> just rotates all the splits, and <C-w> x to switch the current window with the next one. (split - Swap the position of two windows - Vi and Vim Stack Exchange)

Vim search history

:history / (Is there search and replace history in vim? - Vi and Vim Stack Exchange)


Day 176

Linux undelete file on ext filesystem with extundelete

extundelete /dev/sda4 --restore-file directory/file I’m shocked this works, and it can do a lot of interesting stuff - files, directories, list of deleted files, etc etc etc.

Day 172

Tensorflow

Estimators

This is one of the best tutorials I’ve found. Todo: userscript that gives me back the real URL from outline.com.

Tensorflow tensors and graphs

Tensors

A tensor is a generalization of vectors and matrices to potentially higher dimensions. Internally, TensorFlow represents tensors as n-dimensional arrays of base datatypes.

A tf.Tensor object represents a partially defined computation that will eventually produce a value. tf.Tensors do not have values, they are just handles to elements in the computation graph.1

Rank	Math entity
0	Scalar (magnitude only)
1	Vector (magnitude and direction)
2	Matrix (table of numbers)
3	3-Tensor (cube of numbers)
n	n-Tensor (you get the idea)ank	Math entity
0	Scalar (magnitude only)
1	Vector (magnitude and direction)
2	Matrix (table of numbers)
3	3-Tensor (cube of numbers)
n	n-Tensor (you get the idea)

Graphs

A computational graph is a series of TensorFlow operations arranged into a graph. The graph is composed of two types of objects.

  • tf.Operation (or “ops”): The nodes of the graph. Operations describe calculations that consume and produce tensors.
  • tf.Tensor: The edges in the graph. These represent the values that will flow through the graph. Most TensorFlow functions return tf.Tensors.

Python

Python functools partial functions

functools.partial(func[,*args][, **keywords])\

Return a new partial object which when called will behave like func called with the positional arguments args and keyword arguments keywords. If more arguments are supplied to the call, they are appended to args. The partial() is used for partial function application which “freezes” some portion of a function’s arguments and/or keywords resulting in a new object with a simplified signature. For example, partial() can be used to create a callable that behaves like the int() function where the base argument defaults to two

Python lambda for hiding arguments

Same to above, also from Tensorflow: Here we wrap up our input_fn call in a lambda to capture the arguments while providing an input function that takes no arguments, as expected by the Estimator.

input_fn=lambda:iris_data.train_input_fn(train_x, train_y, args.batch_size)

Python argparse

A nice example from the estimator example in tensorflow:

import argparse
parser = argparse.ArgumentParser()
parser.add_argument('--batch_size', default=100, type=int, help='batch size')
parser.add_argument('--train_steps', default=1000, type=int,
                    help='number of training steps')

args = parser.parse_args(argv[1:])

input_fn=lambda:iris_data.train_input_fn(train_x, train_y, args.batch_size), steps=args.train_steps)

Pandas pop column

pandas.DataFrame.pop — pandas 0.24.2 documentation. Works like a list .pop, df.pop('columnname'). Especially handy for ML.

Qutebrowser

Qutebrowser userscripts

Created my first qutebrowser userscript!

#!/bin/bash
echo "open http://outline.com/$QUTE_URL" >> "$QUTE_FIFO"

Qutebrowser edit URL

go - set-cmd-text :open {url:pretty}. wO opens a new window.

youtube-dl and mpv play audio

mpv $url --vid no plays it as audio file.

tmux scroll up

<C-b> PgUp gives me copy mode.

amixer selecting an audiocard

They can be found in alsamixer. Then -c 2, where 2 is the device/card number.: amixer -c 2 set PCM 5%+


Day 171

Pandas apply() memory hell

This is a nice read about how Pandas’ apply needs to store the Series it creates, that there’s no magic, and that inelegant loops can sometimes be faster. Relevant is the official Enhancing performance guide, that I should read.


Day 169

Games

  • Greed is absolutely wonderful and much more interesting than I thought at the beginning.

Day 168

Rclone and backing up Google Drive

rclone is nice. I followed the guide in Google drive, and the magic command to copy all content is rclone sync "drive:Google Photos" /mnt/data/Backups/GP, about 300kb/s, and about 4 hours left.


Day 165

Qutebrowser private windows

Day 155

Using I/we/passive in a Bachelor’s thesis

No easy answer, but I liked here the joke “In your particular case, an inclusive we could be used to recognize the nematodes collaboration :) – Dr. belisarius May 10 ‘11 at 13:01”

  • I asked another young professor whether one could use “I” and she said “Only if you want to sound like an arrogant bastard”, and observed that only old people with established reputations can get away with it.

  • The passive voice should not be used to avoid writing I or we. If the entire thesis is written in the passive voice, it is much harder to read, and the sentences within it1 have to be reworded awkwardly so that some good transitions between the sentences within a paragraph are lost. On the other hand, if some sentences seem to require the passive voice, by all means those sentences should be written in the passive voice. But the passive voice should only be used where it is justified, that is, where its use improves readability of the thesis.

TL;DR use “we”, don’t use passive unless needed; don’t use “I” ever.

Also in Germany it’s bachelor’s thesis, apparently.

Bachelor’s thesis tenses

This is also really nice:

Quotes

“I’ve come up with a set of rules that describe our reactions to technologies: 1. Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works. 2. Anything that’s invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it. 3. Anything invented after you’re thirty-five is against the natural order of things.” — Douglas Adams

Day 150

Vim-mediawiki-editor

vim-mediawiki-editor might make the links wiki fun again for me.

Pandas

Jupyter/pandas output entire text in column without truncating

pd.set_option('display.max_colwidth', -1)
d[['co','otext']]

Pandas count occurrences of value inside a df row (and of values inside a list in a column)

I need to work on my descriptions. d['pos'] contains a list inside every row. I need to count the occurrences of a value inside this list. So I transform the list in a Series and then do value_counts, and each element of the list will be in its own column. The value of each column will be the number of occurrences.

d['pos'].apply(pd.Series.value_counts)

I can do .fillna(0) at the end to put a 0 instead of NaN.

Though this feel awfully slow. (And why doesn’t simply .tolist work?)

(SO)

Pandas latex code output

Apparently if text between two $s in the output of a command gets parsed like latex?

Quotes

Michael Crichton invented the term Gell-Mann Amnesia as a reference to Nobel-winning physicist Murray Gell-Mann, who remarked that even though the newspapers were always wrong about his area of expertise (physics), he always found himself trusting them about everything else. (SSC)

Thesis

0530_final_dataset.csv contains the final cleaned-up dataset with tokens, parts of speech, URIs/hashtags/mentions as their own POS, etc.

Zsh taskwarrior statusline indicator

Changed the statusline to the following:

function task_indicator {
    if [ `task +READY +OVERDUE count` -gt "0" ]  ; then
        #printf "%b" "\u$OVERDUE"
        printf "%b" "!!!"
    elif [ `task +READY +O count` -gt "0" ]  ; then
        #printf "%b" "\u$DUETODAY"
        printf "%b" "!!"
    elif [ `task +READY +A count` -gt "0" ]  ; then
        printf "%b" "!"
    else
        printf "%b" "\u$OK"
    fi
}
task="\$(task_indicator)"
addprompt=$task

Now in zsh the statusline gets changed based on the amount of important tasks still pending. More simple than what was before.

Quotes

In college, I ran a painting business. Every painter I hired had to buy their own brushes. This was one of the first things I learned. Throwing a standard brush at new painters didn’t work. The “company” brushes were quickly neglected and degenerated into a state of disrepair. But painters who bought their own brushes took care of them. Painters who bought their own brushes learned to appreciate the difference between the professional $20 brush they owned and cheap disposable dollar store brushes. Having their own brush engendered a sense of enduring responsibility and craftsmanship. (from Codinghorror “The Programmer’s Bill of Rights)

rsync progress based on all files with pv

Allegedly there’s an official way, though I could not get it working: rsync -a --info=progress2 src dest What works is the second answer: rsync -aix /source remote:/dest | pv -les $(df -i /source | perl -ane 'print $F[2] if $F[5] =~ m:^/:') >/dev/null, and the general way rsync -ai /source remote:/dest | pv -les [number of files] >/dev/null.

To find number of files in general, ` find /source wc -l`.

Day 147

Quotes

There are two sorts of comments - “What” comments and “Why” comments.

“What” comments tell you what the code is doing. In a lot of cases, depending on the language, the need for these can be reduced by writing clear code. This is much easier in, say, Python than Assembly. Even in Python though, sometimes you can be doing something a bit subtle where a 2 line comment can clear things up. These comments aren’t irreplaceable because with a bit of reading and work, you have all the information to work out what is happening.

“Why” comments are much more important - telling the reader WHY the code is doing whatever it is that it’s doing. The ‘trim()’ comment referenced in the article is a great example of a Why comment - all the reading around the code wouldn’t give you an explanation (although sometimes git blame will).

Many ‘what’ comments are superfluous, almost no ‘why’ comments are - they are the collective memory of design decisions that otherwise lives in people’s heads. (HN)

Linux sandboxing

For programs I don’t trust, Firejail seems okay. firejail <appname>.

Android ADB Push

Still works as I remembered it. adb push <sourcefile/s> <location>, where location in my case is storage/sdcard0 for the memory and storage/FD... for the sdcard. adb shell is very nice also.

Vimium close pinned tab

With x, it’s nice, because my usual <C-w> doesn’t close pinned tabs and I have to unpin them to close them.

Markdown inserting images with caption

Apparently this is the officially right way to do it (see SO):

<figure>
  <img src="https://pchr8.net/assets/image.jpg" alt="my alt text"/>
  <figcaption>This is my caption text.</figcaption>
</figure>

I changed it by adding the path in image.html, since apparently you can’t have curly brackets inside includes (I’m not sure how the SO answer works).

Since I may end up doing this often, I created a new include for dtb based on this answer:

<figure class="image">
    <img src="{{site.url}}{{site.baseurl}}/assets/{{ include.url }}" alt="{{ include.description }}">
  <figcaption>{{ include.description }}</figcaption>
</figure>

to be used as

{% include image.html url="thesis/firstdata.png" description='Figure 1. Language of the collected tweets.' %}

On Linkedin there’s a nice description of what should the “related work” section look like.

Day 141: LSDeluxe and Nerd Fonts

LSD and installing fonts in st and urxvt

LSD is a very nice replacement for ls. To set it up, I needed to download the individual fonts from Nerd fonts, cp-ing them to /usr/share/fonts, then running fc-cache -f -v.

To set up the new DejaVu font in urxvt, this is the line in .Xdefaults:

URxvt.font: xft:DejaVuSansMono Nerd Font Mono:pixelsize=12
URxvt.boldFont: xft:DejaVuSansMono Nerd Font Mono:pixelsize=12:weight=bold
URxvt.letterSpace: -1

And in st, config.h is:
static char *font = "DejaVuSansMono Nerd Font Mono:pixelsize=12:antialias=true:autohint=true";

AUR has a BIG nerd-fonts-complete package with all the fonts.

bspwm, polybar and multiple monitors

Following the advice in this article:

bspc monitor HDMI-0 -d 1 2 3
bspc monitor eDP -d 4 5 6 7 8 9 0 a b c

in bspwmrc, and

polybar example &
polybar big &

in launch.sh, and

[bar/big]
monitor = HDMI-0

[module/bspwm]
used = %name%
label-occupied = %name% 
label-urgent = %name%!
label-empty = 

in polybar/config.

Also to make the tray appear only on the right monitor, I commented out ; tray-position = right on the HDMI monitor, now it appears again on eDP.

They work a bit different than i3 – the workspaces I list in each of the monitors in bspwmrc are accessed sequentially via the keyboard. That is, in the config above, f1..f4 get accessed with Mod+1..4, and Mod+5..x access the I..X ones. I think they get cycled from the left monitor to the right one, but definitely not in the order the monitors are set up in bspwmrc and not alphabetically.

bspwm config changes

Stolen mostly from dotfiles in this repo:

bspc config pointer_follows_monitor true # brings pointer to focused monitor (see workspaces)

and in polybar/config

[module/bspwm]
label-empty =

Amongst other things – I’m not sure how to move my windows from the HDMI workspaces if I disconnect the second monitor from the computer, partly it means I’m (I think, for now) limited to a number of workspaces in each of the monitors. I’m not sure I miss the flexibility of this process in i3 - it might be a good opportunity to play with a much more structured number of workspaces. Maybe I don’t need the flexibility as much as I think.

bspwm/firefox go fullscreen (F11) but stay inside the bspwm window

full-screen-api.ignore-widgets in about:config (from here) is the best thing since sliced bread. I can F11 firefox, but it doesn’t occupy my entire monitor, just removes tabs/url/…, and I can still use Tree tabs. It’s very close to what I used to do with pentadactyl. This is freaking awesome.

pikaur full system upgrade

Works the same way as with pacman. Interesting that I never thought about this. sudo pikaur -Syu

redshift change day/night temperature

Updated startup.sh to use redshift with a warmer nighttime temperature: redshift -l 51.34:12.38 -t 6500:3000

Also I’m not sure I like the use -l both for location provider and lat/long info. I think I understand the logic, but still..

Day 139

Bash dtb create.sh script

Updated the script to create a markdown dtb file to the following:

FILE=_posts/$(date +%Y-%m-%d)-day$(date +%j).markdown
DATE=$(date +%Y-%m-%d\ %H:%M:%S\ +0100)

if test -f "$FILE"; then
        vim $FILE
        exit 1
fi

echo "Creating file $FILE"

echo "Adding stuff"

/bin/cat <<EOM >> $FILE

EOM

vim $FILE

Now it’s closer to create_or_open.sh and doesn’t overwrite anything if run again by error, doesn’t add any unused parts, and opens the file if it exists already.

Bash check if file exists

        vim $FILE
        exit 1
fi

Bash exit script

exit 1 or whatever status code.

Bash suppress output of command (bash redirection)

Day 138: bspwm and some configs

After another small pause, here comes another längliches post!

Urxvt -name and settings

I had been trying to get urxvt to play with i3 scratchpads, but when I set the -name setting I got a vanilla URxvt look.

You evidently configured the font for a specific application instance rather than for an application class. (SO). To make your settings always apply, set URxvt.font rather than urxvt.font, etc.

Solved my problem.

Though at the end, I spent some time looking for a way to grep “name” instead of “class” for URxvt in bspwm and gave up, now typing this on a st terminal and loving every second of it!

st

Is the terminal I might start to use everywhere.

In config.h I changed the font to be static char *font = "DejaVu Sans Mono:pixelsize=12:antialias=true:autohint=true";

Bspwm

Decided to give it a try, loving it!

Scratchbox

To implement the scratchbox, used the method described in the Arch wiki.

In bspwmrc,

t -c scratchterm &
bspc rule -a scratchterm sticky=on state=floating hidden=on

In sxhkdrc,

super + minus
    ~/s/scratch

In ~/s/scratch,

#!/usr/bin/env bash
id=$(xdotool search --class scratchterm | head -n 1)
echo $id

if [ "$id" != "" ]
     then
       bspc node "$id" --flag hidden -f
       fi

I added |head -n 1 so it can better deal with possible multiple terminals of this class, in case I have to restart bspwm for whatever reason.

Thesis

I need a plan. Which I will formulate later today. Meanwhile, any of the papers by Volkova seem very relevant to what I’m trying to do. Though I think after a number of them I’m not getting any additional value from them. We’ll see.


Papers will be numbered in green colour with numbers [1], parts in the paper will be numbered in green in a circle and marked (1).

Main points

  • Shorter texts are harder to analyze – try to download more tweets from the users? And mix them to remove style.
  • Grammar checks and replacements are fascinating to do and analyze, do them
  • Baseline for accuracy
  • Download and look at the reddit dataset

Papers

NLI with User-generated Content [1]

Main points
  • The dataset and the L2 project of the Uni of Haifa
  • It has interesting baselines which I can use in my thesis as example..
  • (1) is an example why geography =! language
  • Filtering data from multi-language countries.
  • They have 230 million sentences, much more than I do. Is this the number of examples I need?
  • n-grams etc are very context/dependent, what I mean with TW and political stuff happening. They should yield high acc on training set but generalize poorly.
  • Spelling and grammar
    • original word and correction offered by spell checker
    • Grammar checked by LanguageTool (2)
  • Frequencies of function words
  • Trivial baseline for classification tasks
  • Nice table of how much the features were relevant, p.3596 (3)
  • "”the personal style of whe user may dominate thesubtler signal of his or her native language”
  • Substitutions as suggested by spell checker should be fascinating.
  • Shorter texts are much harder (6)
    Todo
  • Download tweets by the same users to get a bigger corpus of things I can compare them from. Or, to protect myself from the influence of stylistics, just get many many more tweets.
    • If it goes bad – just categorize users with Twitter meta-data as features, and by downloading their last X tweets in a certain language.
  • Much easier to do native/nonnative and language family than language
    Interesting language:
  • To the best of my knowledge,
  • Related but different
  • accurate, albeit not perfect, proxy for the NL of the author.
  • Reasonably robust to

NATLID: Native language identification [2]

Main
  • g authorship profiles
  • NLI is challenging even for humans.
  • in a CNN smaller (2-3) filter sizes work better (3)
  • Ensemble model, with a voting scheme proportionate to the acc of the models (4)
  • Spoken responses are easier to NLI because the written ones are supposed to be more formal and thought-out.
    • Which might be a win-win for my Twitter data. Should be much less thought out than essays, and much more of the L1 should “shine” through them!
  • Highest misclassification between close languages. - This is why I added BR to MX.
    Todo
  • g arc length, downtoners and intensifiers, production rules, subject agreement – as features. (2)

A brief survey of text mining: Classification, clustering and Extraction techinques [3]

Main
  • hard vs soft classification: hard is when you get a result, soft is where you get a probability for result.
    • SVM do hard classification, but you can modify them to give a probability
  • Naive Bayes works for independent input variables..
  • SVM rarely need feature engineering because it selects support vectors itself. It’s robust to high dimensionality. Text classif. is mostly sparse data - a really okay use case for SVMs. (3) is a description of why SVM work so well for NLI.
  • (4) “Text representation has a very large dimensionality, but the underlying data is sparse.” - ESPECIALLY SO FOR MY USE CASE.

  • In topic models, docs are a mixture of topics, where a topic is a prodbability dist over words
TODO
  • Read through again, understand and grok (1) all vector space models and math.
  • Grok Naive bayes.

Text classification: A recent overview [4]

Main
  • Text classification is not too different from ML, main problem is text representation.
  • BoW is not less effective then counting, because words are unlikely to repeat
    • Especially so in my use case!
  • Imbalanced data problem - cost sensitive learning is needed (3)
  • Accuracy is not a good metric for an inbalanced dataset.
    • Both of the above point to a source [4]
Todo
  • g Latent Semantic Indexing
  • g source [4] in this paper
Ideas
  • Ensemble learning, with 2 versions: one with text-dependent (BoW, n-grams), and one without, give results for both (or give the user a choice if I make it an app at the end)

Worst case scenario plan

Just do native vs nonnative, which should be pretty easy. Define native as “UK”

For tomorrow:

  • g adaptor grammar collocations, Stanford dependencies, CFG rules, Tree Substitution Grammar fragments. (Reddit paper, (2))
  • g weaker but more robust (3)

Get things out of your head and into a system that you fully trust. Everything you do should have positive value – it’s either improving you (I put self care and genuine leisure time in here, but not time wasting), improving a relationship, making money, or making one of those other things more efficient. Do high energy and high focus things when you actually have energy and focus; do mindless things when you feel mindless. Do not skimp on self-care, which includes genuine leisure time, good healthy food, exercise, good personal relationships, and adequate sleep. Aim for the “flow state” in everything you do, because you’ll never be better than when you’re so engaged that you lose track of time and place and just get lost in the moment. (How I get things done)

I find that forcing myself to think about those things at the pace of my handwriting brings a ton of clarity to the ideas I’m struggling with or the life issues I’m trying to figure out. (same source)

Analyzing the dataset

What I did

  • Added quite a lot of features.
    • token_count != pos_count.
    • Counts of POS are relative.
  • Currently I have many more UK tweets than others - but I should have at least 10000 tweets for each language.

    Interesting stuff

  • Twitter does not count @replies in its character count
    • This is why sometimes we get such bundles of joy of 964 characters:

It was a small Army Security Agency Station in Southeast Asia that I was doing some work for. They had a shrink and he pulled me aside. In just 10 minutes or so he taught me “breathing”. It wasn’t until the internet that I learned the term mindful breathing. Subsequently I figured out it was some sort of meditation. [..]

He said I was ‘wrapped to tight’. What ever that means. Those guys were all spooks, but I did not have the same clearances. I was an outsider in that regard, but I did eat with them when at their place. I guess he was bored.

He took my blood pressure and then taught me to breathe. Then he took it again. I was surprised at the drop. It hooked me on mindful breathing. It was probably a parlor trick, but it worked. He improved my lifetime health. For that I thank him.

Python multiline comments

Even though stylistically questionable (PEP8 favours multiple multiline comments), one possibility is to use """ mycomment """; when they are not a docstring they are ignored. (source). They have to be indented right though. And feel kinda wrong
Additionally:

triple-quotes are a way to insert text that doesn’t do anything (I believe you could do this with regular single-quoted strings too), but they aren’t comments - the interpreter does actually execute the line (but the line doesn’t do anything). That’s why the indentation of a triple-quoted ‘comment’ is important. – Demis Jun 9 ‘15 at 18:35

Current results

I looked again at the confusion matrix, after having made a copy. It’s quite interesting:

array([[29, 14, 28, 26],
       [38, 57, 36, 27],
       [52, 18, 58, 28],
       [18, 14, 18, 39]])

This is a simple SVM, using extremely simple features, and 2000 examples per class. The columns/rows are: ar, jp, lib, it, in that order. My first error is that Arabic and countries which are around Libya are quite similar in my world, linguistically, and we can see that they are confused quite often, in both directions. Italy and Japan do much better.

  • Get more and better (linguistically more different) data.
  • Work with more interesting features.

Still, ich finde das sehr vielversprechend, and definitely better than chance. And logically it makes sense. I’ll continue.

Countries with the most Twitter users

The list. I’ll stick to Japan, UK, SA, Brazil, India – quite between each other, geographically and linguistically. I leave the US alone, too mixed.

Bounding boxes

This is the picker. DublinCore format is in the identical order as Twitter wants!

Probably the plan would be

  • Getting the dataset
    • Except the 5 languages I already have, add a similar one to the ones already available, to see how much confusion between the two I get at the end.
      • Added Mexico!
  • Preprocessing
    • Replace URLs and @mentions by tags.
    • Replace the actual words with their POS Tags
      • Leaving the Emoticons alone, since they are probably quite geographically distant
      • Leaving the usual punctuation and stop-words alone, since they probably are exactly what I need
    • Remove all usernames which contain ‘bot’ in their username
    • Find all tweets that are similar to each other by whatever metric and remove all of them too
      • This would work much better than what I could manually do, I can’t think of all possible robotic tweets
    • Then tokenize the resulting thing the usual way
  • Ensemble learning
    • I can get a number of classifiers and use some kind of voting procedure
    • BoW is counterproductive in my case, because too many geographical names and topic names. BUT it would be fascinating to get tweets from the same authors a number of years before, and compare if BoW gets less effective for these old tweets. I think it would be too focused for the ephemeral Twitter universe, if there’s an election in Brazil it will happily decide that all tweets containing ‘election’ are Brazilian - a comparison with old tweets would help me test this hypothesis. And give the user a choice at the end if the prediction should be done using everything or everything except BoW.

To research

  • Author profiling
    • By what markers is this usually done? Can I use some of them?

      For tomorrow/later

  • Finish doing the preprocessing script
    • In: the .csv
    • Out: Whatever I can import in Jupyter, with all the features etc

Pandas

Leave rows with values from a certain list

d[d.co.isin(['uk','in'])] leaves the rows where co==’uk’ or co==’in’.

TODO: Why is .loc used here?

Random/thoughts

  • Would putting an uninterrupted block of learning at the very beginning of my day help me?
  • This might become a very nice experiment – do it for 30 days and see what happens. If I sleep well I’m on my best in the mornings, apparently.

Day 100, how nice! I’m glad this diary happened :)

Thesis

Today I’ll try to get as many not-NLP-features as possible – number of things, capitals, punctuation, etc and see if it predicts anything.

Pandas balancing datasets

One way to balance a dataset, to leave an equal number of points in all classes, is the third answer here:

g = df.groupby('class')
g.apply(lambda x: x.sample(g.size().min()).reset_index(drop=True)

For each group, we get a sample from it, with the size of the smallest group. Quite beautiful actually.

Basic non-NLP classification

I added the following columns:

  • char_count, word_count, word_density
  • puctuation_count, title_word_count, upper_case_word_count – though all relative, that is divided by number of words

Basic classification using scikit and the very basic features above. With four languages and the vanilla sklearn.svm.SVC I get the following confusion matrix:

array([[34, 22, 30, 24],
       [26, 49, 24, 29],
       [30, 33, 45, 25],
       [32, 22, 34, 41]])

which is still more than chance!

To print:

Papers with code

PWP is probably the best resource I’ve come across.

Language interference

Reddit about this topic – I think I need to narrow the field of the thesis and focus on two languages.

Ensemble learning

…would be very interesting to use. “Native language identification using ensemble learning” is a nice title. :) And gives me the opportunity to play with really a lot of algorithms.

Recording microphone and speaker

With openbroadcaststudio, obs. For now it creates a video, to extract the audio: ffmpeg -i 2019-04-10\ 18-27-43.flv -map 0:1 -vn output.ac3.

Todo: how to do it without obs, or with obs – how to do it without video.

Taking screenshots at regular intervals

The command is pretty predictable:

while true; do scrot -d 5 '%Y-%m-%d-%H:%M:%S.png' -e 'mv $f ~/Pictures/'; done for every 5 seconds

Python

Chained try/except blocks

Apparently this is the recommended way to do this, as per this answer and the official Python docs:

def __getattribute__(self, item):
    try:
        return object.__getattribute__(item)
    except AttributeError:
        pass  # fallback to dict
    try:
        return self.dict[item]
    except KeyError:
        raise AttributeError("The object doesn't have such attribute") from None

Easier to ask for forgiveness than permission. This common Python coding style assumes the existence of valid keys or attributes and catches exceptions if the assumption proves false. This clean and fast style is characterized by the presence of many try and except statements. The technique contrasts with the LBYL style common to many other languages such as C.

Get file name without extension

os.path.splitext("path_to_file")[0]

Bash adding symbols to filenames

Adding a + to all the files in the current directory, before the extension: for file in *.jpg; do mv $file $(basename $file .jpg)+.jpg; done (from here)

German

Wann vs wenn

Wann vs wenn: Wann has nothing to do with if, it’s a question asking for a point of time. Wenn is closer to “if”, but it’s also a translation for “when”.

If we can say at what point time instead of when, then we need to use wann.

Wann [=at what time/when] kommt der Bus? \ Bis wann musst du arbeiten?
Thomas fragt Maria, wann genau sie nach Hause kommt.

On the other hand,
Ich gehe nach Hause wenn[!= at what time! just the “when” closer to “if”] ich fertig bin.

Roles

A wann-clause is ALWAYS functioning as the object of the verb.. If I can replace the clause with a thing, then it’s wann.\ Wenn answers to “at what time”, we can basically replace it with “at 3 am”.

When I have finished work, I will call you and tell you when I will be at home.
When I have finished work, I will call you and tell you at what point in time I will be at home.
Wenn ich mit der Arbeit fertig bin, rufe ich dich an und sage dir, wann ich zuhause bin.
At 3 I’ll call you and tell you this thing.

Github reset (undoing last commit/s)

$ git reset --soft HEAD~1 resets to last commit leaving all the changes on disc, but uncommitted.
$ git reset --hard 0ad5a7a6 returns to any previous version.

Classifying by parts of speech

nltk.download() downloads everything needed. nltk.word_tokenize('aoethnsu') returns the tokens. From https://medium.com/@gianpaul.r/tokenization-and-parts-of-speech-pos-tagging-in-pythons-nltk-library-2d30f70af13b. For parts of speech it’s nltk.pos_tag(tokens).

The tokenizer for twitter works better for URLs (of course). Interestingly it sees URLs as NN. And - this is actually fascinating - smileys get tokenized differently!

 ('morning', 'NN'),
 ('✋', 'NN'),
 ('🏻', 'NNP'),

EDIT: nltk.tokenize.casual might be just like the above, but better!

EDIT: I have a column with the POS of the tweets! How do I classify it with its varying length? How can I use the particular emojis as another feature?

Ideas

POS + individual smileys might be enough for it to generalize! TODO test TODO: Maybe first do some much more basic feature engineering with capitalization and other features mentioned here:

    Word Count of the documents – total number of words in the documents
    Character Count of the documents – total number of characters in the documents
    Average Word Density of the documents – average length of the words used in the documents
    Puncutation Count in the Complete Essay – total number of punctuation marks in the documents
    Upper Case Count in the Complete Essay – total number of upper count words in the documents
    Title Word Count in the Complete Essay – total number of proper case (title) words in the documents
    Frequency distribution of Part of Speech Tags:
        Noun Count
        Verb Count
        Adjective Count
        Adverb Count
        Pronoun Count

Resources

textminingonline.com has nice resources on topic which would be very interesting to skim through! Additionally flair is a very interesting library not to reinvent the wheel, even though reinventing the wheel would be the entire point of a bachelor’s thesis.

This could work as a general high-levent intro into NLP? Also this.

Knowledge/plans management

I just discovered didoesdigital.com, which is absolutely excellent on all levels. I’m missing a way to categorize everything I see there.

I should/could make things-I’m-learning pages with links and checklist for things I’m doing/learning. I’m not quite sure what should it look like, but it would definitely be something Jekyll-like. I think I’m slowly going in the direction of Steve Wolfram’s dashboard. Or at least a different vim in a different floating window that opens with another keystroke, i3 would make it easy to do that. In general I need a much better system to track the things I’m learning or reading. Polarized goes in the right direction. And I feel my links wiki will stay just that – a links wiki. Unless I make a seamless interface to it, I don’t really like it for actual knowledge management, even though it’s the absolute best I have until now.

And I must not fall in my typical error about sharpening the saw more that actually cutting trees, even though sharpening the saw is a really pleasant thing to do for me.

EDIT: Just created it at here, we’ll see what happens. I can imagine a dashboard based on it, and some kind of integration for task/timewarrior. Probably something ncurses-based in python?

Trickle lists

This is the application - in general I find the idea really inspiring. I could imagine it on a touchscreen somewhere, or at least on a second desktop. Is it conceptually different from Nomie? Can I add just add another “trickle” board?

Jekyll deploy.sh

Added at the end ./commit.sh, which is a small file with git commit, so now it gets backed up to github automatically every time I deploy a new version on the server.

HoMe diploma

I’m starting again to work heavily on my diploma. I’ll be documenting most of what I do and learn here, and I think after this this semi-blog will become even more lively. I don’t think anyone will feel bad about me using this as my personal notepad, because this is exactly how this place was envisioned. For the “blog” blog with a bit more curated posts, feel free to go there.

The plan

In the next couple of days - read maximally about interference in languages, first language identification etc. sci-hub.se - do a better cleanup of the tweets dataset (file for preprocessing it in batch instead of the same way in every notebook) - do some basic classification with tokens standing not for words, but for parts of speech, and with commas included, and see if that brings anything interesting (as per the influence/punctuation paper). - Create a working systemm for notes, papers, links etc etc. Most probably Note.vim or whatever was it called, but I need to research what exist. .. Or my wiki, which is nominally for knowledge management, and I’ve never seen a purer use-case for this.

Python

Importing modules

Modules downloaded from Github and placed in the same directory get prioritised automatically, because the first thing inside sys.path is an empty string, which represents the current folder the file runs from.

Encodings

Are hell. I solved the problem of my utf-8 text being represented with weird \wha\te\ver characters while being utf-8 by changing the way csv is written. The old csvwriter.writerow([str(status.id_str).encode("utf-8") got replaced by csvwriter.writerow([str(status.id_str). It was wrong and now I understand why. It was writing the utf-8 bytes in the file, and when I read I got a string with the slashed that was already utf-8, the individual ‘', ‘w’ .. characters, not bytes.

Day 083: Fun with i3-gaps and work/play mode

i3

i3-gaps for work/play mode

i3-gaps is fun but kinda nothing more. But I think it has potential for creating a right atmosphere for my work/play time and pomodoros.

I added the following in the config:

# work
bindsym Mod3+w exec feh --bg-scale ~/s/bg/darkwood.jpg; gaps inner all plus 10
# play
bindsym Mod3+p exec feh --bg-scale ~/s/bg/wallpaper.jpg; gaps inner all plus 10

The idea is that there are two main designs, activated by the above keystrokes, one with gaps which I’ll use when I’m not doing anything important, and the other one when I have a timer/pomodoro running. Like a ritual and a way to subconsciously signal to myself that I should not distract myself right now.

We’ll see if it works out.

See if there's a way to do this on all workspaces. Is this what the global/local config thing is about?

yes. gaps inner all plus 5

i3-wpd from Github is nice. Could be another way to ritualize it all. We’ll see.

Day 077: Creating albums from scanned pictures

Automagically cropping pictures

This tutorial and extension could separate about 30% of the pictures with the default settings. Margins (and margins to the sides of the image!) are important.

Installing GIMP .scm plugins

is done by putting the .scm file to /usr/share/gimp/2.0/scripts/

Creating LaTeX photoalbums

This tutorial is freaking awesome.

Given the number of images I was dealing with manually configuring each one was not an option. What I wanted was a service that would, given my image collection, just print me a photo album of approx 6x4 images, in chronological order, two per page, with a caption below each detailing the image file name and the date taken.

It provides a .tex album file and a Python2 file which reads the Exif data and creates a photos.tex which gets included in the main album file.

Day 073: setting up scanning

Printing and scanning

scanimage (SANE) is a “a library and a command-line tool to use scanners”.

sudo scanimage -L to see the list of scanners, then to scan (for me also with sudo for some reason): sudo scanimage --device "xerox_mfp:libusb:002:004" --format=png > name.png


Day 062: Fixing my timer scripts, Jekyll pagination and excerpts and "unless"

Arch linux thumbnails

The package is tumbler.

Fixed my timers (Bash, redirects, >)

I had two problems with my timer system: that it doesn’t work when the files are empty (because of the split I did in the code), and the files that grew exponentially, because they did not get deleted at the end of the timer.

I am not sure why did the > in the timer command leave the previous file contents (I assume it’s some magic with terminals and ^M?), but I fixed it by adding : > outfile to the command at the beginning.

From this tutorial:


   : > filename
      # The > truncates file "filename" to zero length.
      # If file not present, creates zero-length file (same effect as 'touch').
      # The : serves as a dummy placeholder, producing no output.

   > filename
      # The > truncates file "filename" to zero length.
      # If file not present, creates zero-length file (same effect as 'touch').
      # (Same result as ": >", above, but this does not work with some shells.)

My zsh was apparently one of the shells where that doesn’t work, but the first one worked nicely. So the final line in .i3/config is:

    bindsym Mod3+n exec ": > ~/s/sounds/outpomo && utimer -c 15m > ~/s/sounds/outpomo && mpg123 ~/s/sounds/tib.mp3"
    bindsym Mod3+Shift+s exec ": > ~/s/sounds/outpause && utimer -c 5m > ~/s/sounds/outpause && mpg123 ~/s/sounds/cl.mp3"

The files-not-existing thing was fixed by an additional try/catch block. The final (still bad) code looks like this:

    while True:
        line, prefix = read_line(), ''
        # ignore comma at start of lines
        if line.startswith(','):
            line, prefix = line[1:], ','

        j = json.loads(line)

        # Files with the output of utimer:
        tfile="/home/sh/s/sounds/outbash"
        tfile2="/home/sh/s/sounds/outpomo"
        tfile3="/home/sh/s/sounds/outpause"

        def rtime(tfile, color):
            try:
                with open(tfile, "r") as f:
                    # last line of the file
                    try:
                        t=f.readlines()[-1] # If file is empty
                    except IndexError:
                        t="O"
            except IOError: 
                # If the file doesn't exist at all
                t="O"
            # Utime seems to add a \n(^M?); at the end
            # We use it as a way to check that the timer has stopped
            # When it stops, a \n is added.
            if "\n" not in t:
                if t!="O":
                    to=t.split("ing:")[1]
                    j.insert(0, {'full_text': '%s' % to, 'color':'%s'%color})

        tcolor1="#FF0F02"
        tcolor2="#FFFFFF"
        tcolor3="#FA0FF2"

        rtime(tfile, tcolor1)
        rtime(tfile3, tcolor3)
        rtime(tfile2, tcolor2)

Jekyll pagination fun

Pagination – highlighted posts

I wanted to output the first couple of posts in full, and the next ones until the end of the page as excerpts for the first page, and for all the next pages – only the excerpts. This SO answer helped me, I didn’t know about offset and limit in for loops!

      <ul class="post-list">
        <!-- This loops through the paginated posts -->
        <!-- If we're on the first page, output the first 3 posts in full-->
        {% if paginator.page == 1%}
          {% for post in paginator.posts limit:3 %}
          <h1><a href="{{site.url}}{{ post.url }}">{{ post.title }}</a></h1>
            <p class="author">
              {% assign date_format = site.minima.date_format | default: "%b %-d, %Y" %}

Pagination – removing the pages from the header with unless

I’m not sure what happened, but I saw all the generated paginator pages in the menu, all called “Posts”. I removed it by overriding the layout with unless, which is another really nice operator.

The relevant code in _includes/header.html:

        <div class="trigger">
          {%- for path in page_paths -%}
            {%- assign my_page = site.pages | where: "path", path | first -%}
            {%- if my_page.title -%}
            {% unless my_page.title == "Posts" %}
            <a class="page-link" href="{{ my_page.url | relative_url }}">{{ my_page.title | escape }}</a>
            {% endunless %}
            {%- endif -%}
          {%- endfor -%}
        </div>

Day 061: Basic bash scripting

Bash

I needed to copy all pictures from a folder to another place, while saving the paths and folder names. (from/one/two/three.jpg should become to/one/two/three.jpg)

The images were inside a number of different directories and doing it manually would’ve been hell.

Therefore, first I found all images and wrote their full path to a file: find . -type f -exec file {} \; | awk -F: '{ if ($2 ~/[Ii]mage|EPS/) print $1}' >> ~/allm (I’m not pretending I understand the above line).

Then I wrote this basic script to create the folders and to copy the files inside them. This was much harder than expected, especially because of the spaces inside the filenames, which created problems at every step.

The final code was:

counter=0; # To count how many files have we copied
IFS=$'\n' #makes newline the only separator, not just spaces, in the next line.
for o in $(cat allm) # for every line inside the file allm
do
    echo =========== $counter ==========
    counter=$((counter+1)) #increase counter

    # Everything inside quotes because apparently that's how you do spaces. Also all the names are inside variables, because again apparently that's how you do spaces.

    directory=pictures/$(dirname from_white_210220019/"$o")
    from="from_white_210220019/$o"
    to="pictures/from_white_210220019/$o"

    mkdir -p $directory

    echo "copying (from to)" $from $to
    cp ${from} ${to}
done 

The IFS thing decides how should the elements of the file be split. By default it’s spaces and newlines, we needed to tell it to split only by newlines, explicitly.

The entire solution is quick and dirty (the “from_white_xxx” thing would be the first thing to refactor) but it works, no need for overengineering a quick one-time hack which I’ll prolly never need again.

Keynav scrolling

This is a nice discovery!

Q: Can I use keynav to scroll?
A: Yes! X11 represents mouse scrolling as key presses, so you just add the relevant stanza to your keynavrc. Mouse buttons are 1=left, 2=middle, 3=right, 4=scroll-up, 5=scroll-down, 6=scroll-left, 7=scroll-right. So for example to scroll up with i and down with e:

i click 4,end
e click 5,end

Day 058: Vim and Timewarrior

Taskwarrior excluding stuff

To exclude tasks of a certain project, the syntax for the filter is project.not:projectname.

Also added a new report for tasks which will never be finished – anki, cleaning, basic org etc., but that I still want to track with timewarrior. t m now returns me all such tasks.

Vim searching at the beginning of line / that start with something

I find myself grepping through the dict.cc raw file, I might build a script to do that for me. But I often need to find a word with the condition that it’s the first thing on a line, instead as partof a bigger sentence.

^ helps. /^Dru gives me the lines which start with “Dru”.

Linux exit codes

To check the exit code of a command you just ran, you need to output the special bash variable $?, so echo $? returns the exit code of the previous command.

Taskwarrior

I decided to make my sprint system a bit less stupid than it is now. I finally rewrote it using overrides.

In .zshrc, first I override the default sprint when adding tasks, then create command which shows my s report:

alias t='task rc.uda.sprint.default=$SPRINT'
alias s='task s sprint:$SPRINT or sprint:c' 

in .taskrc I modified the s report to look like this:

# Current sprint
report.s.description='Current sprint'
report.s.columns=id,project,tags,pri,est,due.relative,description,urgency
report.s.labels=ID,Project,T,P,E,D,Description,U
#report.s.sort=due+
report.s.sort=urgency-
report.s.filter=status:pending

Now when I type s I get my current sprint todo, and when I add tasks they get added automatically to current sprint.

Day 049: Python

Timewarrior

Apparently times and intervals are much more easy than I thought! I should actually read man pages sometime, instead of relying on tutorials.

INTERVAL
       An interval defines a block of time that is tracked. The syntax for specifying an interval is flexible, and may 
be one of:

         [from] <date>
         [from] <date> to/- <date>
         [from] <date> for <duration>
         <duration> before/after <date>
         <duration> ago
         [for] <duration>

       Examples are:

         from 9:00
         from 9am - 11am
         from 9:00:00 to 11:00
         from 9:00 for 2h
         2h after 9am
         2h before 11:00
         2h ago
         for 2h

       An interval is said to be 'closed' if there is both a start and end, and 'open' if there is no end date.

Nice examples are, for example, w track 7min "something short" – which records something done the last X minutes including now, as a closed interval.

Linux

Unix date command

Decided to do my sprints system smarter, and decided to set date up to automatically output the week number. I had issues with the padding zero in the export SPRINT=$(date +%U)

The dash after % removes them from the output: export SPRINT=$(date +%-U)

Awesome.

Rsync update behaviour

rsync usually copies files if they are not on the target filesystem. The --update flag makes it check the timestamps, and overwrite if the target file is older than the source file. -c means also check the checksum.

Rsync slash

Trailing slash after the directory name copies the content of the directory, not the directory itself. Not consisten with mv, cp etc.

Vnstat for traffic monitoring

vnstat is the package and the service that needs to be enabled, and in /etc/vnstat.conf the default interface needs to be set.

Mount by UUID

to do this through mount, if for some reason I’ll need to do it manually: sudo mount UUID=%theUUID% /mnt/sth

Taskwarrior and i3

A task gains an +ACTIVE tag if it’s started. I want to use it to get an output of the currently active task in my statusbar.

t +ACTIVE | sed '4!d' gives the line with the currently active task. With sed I can get the needed column: I created a new report in taskwarrior because I did not want to think of columns. Then in the i3wrapper.py I added the following:

    bashCommand = "task a | sed '4!d'"
    bashOutput = subprocess.check_output(['bash','-c', bashCommand]).decode('utf-8').strip('\n')

It works!

Bash and Taskwarrior – tasks with a periodicity

Once every 12 sprints / 3 months brush, once a month backups, I’ll think what else:

for o in $(seq 9 12 52) do
    t add sprint:$o project:h change toothbrush +MOD
done

Day 046: Linux keyboard LEDs.

Linux LEDs and triggers

You can control LEDs with files! Article.

/sys/class/led has folders, with the most interesting files being brightness and trigger. The first one is self-explanatory – echo 1 > brightness does what you would expect it to do. trigger is interesting, cat trigger gives the possible trigger, which you can activate by echo trigger_name > trigger. I connected disk-read to the scroll LED on my USB keyboard, to get a bit of the nostalgic Pentium 4 feels, and BAT0-charging-blink-full-solid to Caps lock, which makes it solid 1 when full and blinking when charging. That was fun.

Jekyll

Jekyll/Markdown comments

… exist in really a lot of variants which are not portable, the portable ones are complicated.

Thankfully, for Jekyll the following exists:

{% comment %} my comment {% endcomment %}

… and of course the HTML comments, but they will still show up in the source.

Markdown numbered lists

… work with any numbers, in any order!

Jekyll Cyrillic and Unicode categories

seem to be a problem. The suggested approach with HTML Entities didn’t work for me, but this workaround did:

  {% assign selection = site.posts | where:"categories","montañas" | limit:1 %}
  {% for post in selection %}

  {% endfor %}

Changing themes

To change/overwrite individual theme files, just create the needed folder/file and do the changes needed. It will include it to the used theme automatically. (Doing the best menu in history).

Quotes

  • Success is measured in output of value, not input of effort

When to Hold onto Information
If the following conditions are met, it may be better to hold off explaining a new problem to your manager:

  • The situation does not require immediate intervention (i.e. no laws broken, no lives at risk, no bank accounts being drained, etc.)
  • You’re waiting on additional information that will make the scope of the issue clear
  • You control the flow of information, and your audience won’t learn about the issue from other sources
  • It’s possible that the situation can be fixed soon, allowing you to communicate both the problem and solution together
  • You suspect there may be related problems lurking that should be disclosed together

  • “Keeping options open” often means “Not being successful in anything”. (from Shulamit Widawsky’s answer)

Day 045: Finishing moving Wordpress to Jekyll

Cooking

As I was looking for ideas for small businesses, I found this nice website with small easy microwave recipes: https://www.minmaxmeals.com/recipes/garlic-oatmeal/, and I’ll try today the linked one. In general having such a database of go-to dishes would be quite nice, because I forget about mine often.

Jekyll

Categories

For categories, I again used this nice tutorial.

Excerpt separator

When outputting posts, {{post.excerpt}} either takes the first paragraph or a separator. The separator can be set in config.yml: excerpt_separator: <!--more-->

Posts visibility

published: false in the front matter. I like this more than the official draft mechanism.

Vim

Deleting tags surrounding something

A really elegant way to delete the tags surrounding something: yitvatp

Tag blocks                      *tag-blocks*

For the "it" and "at" text objects an attempt is done to select blocks between
matching tags for HTML and XML.  But since these are not completely compatible
there are a few restrictions.

The normal method is to select a  until the matching .  For "at"
the tags are included, for "it" they are excluded.  But when "it" is repeated
the tags will be included (otherwise nothing would change).  Also, "it" used
on a tag block with no contents will select the leading tag.

Repeat the last used macro

Just discovered this randomly after a typo. @@ repeats the last @-macro I used. This will save me really a lot of time!

Python forcing named arguments in function

In this article, this nice way has been mentioned: def safe_division(*, number, divisor, ignore_overflow, ignore_zero_division): It forces all arguments after * to be named during call: >>> safe_division(number=10**1000, divisor=3**-100, ignore_overflow=True, ignore_zero_division=False)

Changed date string in statusbar to show also the week/sprint number and weekday:

tztime local {
        format = "[%U] %a %Y-%m-%d %H:%M:%S"
}

Moving my Wordpress to Jekyll

… since I started disliking the new Wordpress interface and stopped using it, it is kind of a security problem, but there are too many memories there to just delete it.

Using Jekyll Exporter, the Wordpress plugin, I could get all the posts and all the pictures to a new Jekyll blog. I also wanted the private posts, which should have been a one line change in its source, and it was:

 foreach ( $post_types as $post_type ) {
     //$ids = $wpdb->get_col( $wpdb->prepare( "SELECT ID FROM {$wpdb->posts} WHERE post_status = 'publish' AND post_type = %s", $post_type ) ); // SHSHSH
     $ids = $wpdb->get_col( $wpdb->prepare( "SELECT ID FROM {$wpdb->posts} WHERE post_status = 'publish' OR post_status = 'private' AND post_type = %s", $post_type ) );
     $posts = array_merge( $posts, $ids );
 }

It created a 307mb file.

Old blog stays online just a bit more, I’ll clean up the posts and stuff and think about how I want to change the home page. We’ll see.

Escaping things

I predictably had problems with my posts containing curly brackets. This is the solution:

{% r.aw %}
{{#set:
 o=true
 |c=8
}}
{% end.raw %}

Four indentations so that it gets recognized as code.

Replacing with newline

%s/aoeu/aoeu\r/g Same syntax as useful, except \r instead of \n for the newline.

\n matches an end of line (newline), whereas \r matches a carriage return. On the other hand, in substitutions \n inserts a null character whereas \r inserts a newline (more precisely, it’s treated as the input )

(from here).

:%s/<\/pre>/\r{% end.raw %}/g  `.

Replace end.raw for endraw, because of this problem which is still around?

Interesting

Nasa’s 128 lessons of a project manager. Highlights:

None of these are original–It’s just that we don’t know where they were stolen from!

  1. Wrong decisions made early can be salvaged, but “right” decisions made late cannot.
  2. Never make excuses; instead, present plans of actions to be taken.
  3. One of the advantages of NASA in the early days was the fact that everyone knew that the facts that we were absolutely sure of could be wrong
  4. If you have a problem that requires the addition of people to solve, you should approach recruiting people like a cook who has under-salted, i.e., a little at a time. 25 Know the resources of your center and if possible other centers. Other centers, if they have the resources, are normally happy to help. It is always surprising how much good help one can get by just asking.
  5. Redundancy in hardware can be a fiction. We are adept at building things to be identical so that if one fails, the other will also fail. Make sure all hardware is treated in a build as if it were one of a kind and needed for mission succes
  6. It is mainly the incompetent that don’t like to show off their work.
  7. Mistakes are all right, but failure is not. Failure is just a mistake you can’t recover from; therefore, try to create contingency plans and alternate approaches for the items or plans that have high risk.
    • Here it’s quite interesting how you have two different attitudes to plan-B. I guess the more costly failure is, the more okay Plan-Bs are considered.
  8. NASA Management Instructions (NMI’s) are written by another NASA employee like yourself; therefore, challenge them if they don’t make sense. It is possible another NASA employee will rewrite them or waive them for you.
  9. A working meeting has about six people attending. Meetings larger than this are for information transfer.
  10. All problems are solvable in time, so make sure you have enough schedule contingency– if you don’t, the next project manager that takes your place will.
  11. Just because you give monthly reports, don’t think that you can abbreviate anything in a yearly report. If management understood the monthlies, they wouldn’t need a yearly.
  12. Sometimes the best thing to do is nothing. It is also occasionally the best help you can give. Just listening is all that is needed on many occasions. You may be the boss but, if you constantly have to solve someone’s problems, you are working for him.
  13. Remember, it is often easier to do foolish paperwork than to fight the need for it. Fight only if it is a global issue which will save much future work.
  14. You cannot watch everything. What you can watch is the people. They have to know you will not accept a poor job.
  15. The first sign of trouble comes from the schedule or the cost curve. Engineers are the last to know they are in trouble. Engineers are born optimists.
  16. There is no greater motivation than giving a-good person his piece of the puzzle to control but a pat on the back or an award helps.
  17. Don’t assume you know why senior management has done something. If you feel you need to know, ask. You get some amazing answers that will dumbfound you.
  18. If you have someone who doesn’t look, ask, and analyze, ask them to transfer.
  19. There are still some individuals who think important decisions are made in meetings. This is rarely the case. Normally, the decision-makers meet over lunch or have a brief meeting to decide the issue and than (at a meeting called to discuss the issue) make it appear that the decision is made as a result of this discussion.
  20. In political decisions, do not look for logic – look for politics.
  21. In dealing with international partners, the usual strategy is to go 1 day early, meet with your counterpart, discuss all issues to be brought up at a meeting, arrive at an agreeable response (or a decision to table the issue for later discussion), and agree not to take any firm positions on any new issues brought up at the meeting. This makes it appear to the rest of the world that you and your counterpart are of one mind and that the work is in good hands. All disputes are held behind closed doors with the minimum number of participants.
  22. Too many people at Headquarters believe the myth that you can reduce the food to the horse every day till you get a horse that requires food. They try to do the same with projects which eventually end up as dead as the horse.

Although it’s not part of Jerry’s written Lessons Learned, he consistently told his people the following (unwritten lesson):

“Show up early for all meetings; they may be serving doughnuts”

Finally, Les Meredith (former Director of Space Sciences and Acting Center Director) had this remark to make about Jerry Madden’s 128 Project Managers’ Lessons Learned:

“God only gave us Ten Commandments. Jerry has listed over a hundred instructions for a Project Manager. It is evident a lot more is expected from a Project Manager”

Day 039: Backups, Linux

Goals for today:

  • learn the number line on the keyboard
  • see what I want to do with my domains and projects
  • Finish my backup system, and do one big backup of everything
  • look at my steno thing and decide what I want to do with it
  • ssh keys for everything
  • finish the basic 3 stones game bot thing, especially the turns part
  • clean everything old and unneded from pchr8.net, to make backups easier and to save money

  • Download maximum audios and videos from my VK accounts
  • move my blog to jekyll?

Downloading files with wget

Savefrom.net has a Firefox addon. I needed to disable various tracking stuff in configs, and let it generate my 7000+ links from the album. Then I’m trying to download them from the file via the following command: wget -i urls1000 -U "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:64.0) Gecko/20100101 Firefox/64.0" --wait=1 --random-wait --limit-rate=2000k --rejected-log=rejected

wget -i inputfile downloads the urls in the file, everything else is me trying not to get banned by the server. Let’s see if it works out.

Linux

du

Here I learned about du. sudo du -h -d 1 shows the size of the directories in the folder (depth of one, human-readable).

Borg

Borg is an awesome backup program which allows to do most of what I need, the link is the quickstart guide.

sshfs

Is a really neat way to access remote hosts’ folders.

Extracting tar to a specific directory

tar xf file.tar --directory /path/to/directory, the --directory option, as per man tar, is

-C, –directory=DIR Change to DIR before performing any operations. This option is order-sensitive, i.e. it affects all options that follow.

SSH executing remote commands

ssh user@host 'echo "test">> test;'. More examples here

Mysqldump

An excellent way to back it up. If it’s local, one way to do it:

name=$(date '+%Y%m%d_%H%M%S')
mysqldump --all-databases >> "arith-mysql-$name.sql"

    local N="$1"; shift
  (utimer -c > ~/s/sounds/outbash $N && mpg123 -q ~/s/sounds/tib.mp3  &
      zenity --info --title="Time's Up" --text="${*:-BING} \n\n $(date +'%H:%M:%S %d/%m')")
}

\n for the newline, $() to insert command output in variable (though if I understand right backticks would have also worked), and date’s format because I will probably remember the year.

EDIT Doesn’t output the date when the timer was set, only when executed :C Need to move it to its own variable, I gues TODO for tomorrow. EDIT2 DONE!

tm() {
    local DATE=$(date +'%H:%M:%S %d/%m')
    local N="$1"; shift
  (utimer -c > ~/s/sounds/outbash $N && mpg123 -q ~/s/sounds/tib.mp3  &
      zenity --info --title="Time's Up" --text="${*:-BING} \n\n $DATE")
}

Python

The googletrans python module uses Google Translate’s web api to translate text. Look extremely useful, I should make a small CLI script for this. I seem to translate random stuff quite often.

Day 20. DT

Typing

https://www.typingclub.com/sportal/program-3/328.play has a Dvorak layout!

Scratchbox/stack

  • it would be interesting to make a static structure for these entries. And then make a template for them, with the right name/date/…
    • DONE! Made a script for this.

Interesting stuff for later

Stenography! With plover and this tutorial. It’s what I was trying to do but much much better on so many levels. The world is a really fascinating place. Installed plover, I will definitely play with it later. “Steno Hero” also exists.


Day 19. DT

Random / news

I discovered https://hckrnews.com/, its “top-10%” setting is awesome.

Scratchbox/stack

  • Finally learn English apostrophes
  • It would also be interesting sometime later to analyze the words used in these entries

Quotes

I feel like being obsessed with anything automatically makes it unattainable. It’s like the universe saying, “ you’re not behaving in a healthy way so you have not earned it being yours.” Its a handy way to keep myself in check. (Reddit.

German

Finally figure out the Unterschied between the words Unterschied u. Unterschiedlichkeit From this German StackExchange answer:

  • Anders
    • Only word that works alone, without saying different from what
    • Der Hund is anders; der andere Hund.
  • Unterschiedlich
    • An important but small attribute that makes things different that you want to accentuate:
      • Wuffi und Kläffi sind unterschiedlich. Sie unterscheiden sich an den Ohren: Wuffi hat Stehohren, Kläffi hat Schlappohren.
  • Verschieden
    • Just different, without any specifics.
      • Natürlich sind Kläffi und Törti verschieden! Es sind schließlich verschiedene Rassen!

Not from dict.cc, but from my intuition:

  • die Unterschiedlichkeit – the difference in a more abstract meaning.
  • der Unterschied – the difference – especially one in particular.

Mechanical keyboards

Here are tips on how to improve ergonomics for better typing speed and comfort. TL;DR raise my wrists and lower my table/keyboard till I get a >90C angle.


Day 18. DT

Today I’ll get my mechanical keyboard <3

Deutsch

  • Finally figure out bzw.

Scratchbox/stack

  • Should I find a way to synchronize all my stacks? TG+T+Jekyll+…
    • Probably not
  • Vim – add a way to delete things without it going to the y-regester
    • "_d does this through the black hole register!

Day 17. DT

Scratchbox/stack

  • More ideas for xkb fun:
    • In vim, make nice shortcuts for usual things I use based on the mod/alt key or the Alt+F2
      • DONE
  • Why did the .html file extension survive better than .htm, but the same didn’t happen for .jpeg?

Day 16. Xkb + cooking

Mediawiki

  • [[File:File.jpg]] to use the full version of the file
  • [[File:File.png|200px|thumb|left|alt text]] to use a 200 pixel wide rendition in a box in the left margin with “alt text” as description
  • [[Media:File.ogg]] for directly linking to the file without displaying the file

copied directly from the Special:Upload page.

Jekyll

If I make a post’s date in the future it will not appear until then? TODO research how does it work.

Scratchbox/stack

  • I need a way to finally organize all the things I finally want to (invest time to) learn. I seem to lose quite a lot. I need something more formal than my link wiki for this, I think. Or just change how I use it.
  • Add to TW a planned-due field! As opposed to the real-deadline.
    • Add to TW and create a system for some tasks for the year in the respective sprints, like change toothbrush every 3 month. Things with >1m periodicity.
  • Add zsh aliases for compiling & uploading this Jekyll blog.
    • DONE
  • And finally fix the public and private keys

XKB Fun

Cooking

Couscous! Here is how to cook and ideas.

Also champignons in the oven.


Day 15. DT

Sport

I will be doing the Stronglifts 5x5 program in February! Should also read this. And follow the drink a lot of milk calorie gain thing.

Timewarrior

  • For tasks with parentheses, they need to be escaped \(like this \), so that they don’t conflict with zsh.
    • Speaking of which, what do they conflict with?
  • I should finally remember that it’s shorten @1 20min for timew, and 20m for utimer. I think it’d be easier to fix utimer than timew – I need to make them identical either way. I guess hypothetical TODO for later.

Scratchbox/stack

  • I should learn the names of the German letters: https://de.wikipedia.org/wiki/Deutsches_Alphabet#Benennung_der_Buchstaben.
  • Learn bash/zsh parentheses – what do they do exactly.
  • I could make a specific i3wm-config for when I want to do Deep Work in Cal Newport’s meaning of the word? With different background and only two workspaces or something like this. Bonus points if I can switch to it dynamically.
  • T add the dynamic font size change perl addon to urxvt
  • I should make two different kinds of Scratchboxes – the ones which are time-sensitive and ones that are not.
    • And I should learn to ignore thoughts which are inconsequential and not with no chance to ever be acted on.
  • Add to my timer the ability to do “tm 15:00” or something.

Deutsch

  • der Pfad - die Pfade -> trails/paths
    • abseits ausgetretener Pfade – off the beaten track
    • TODO Ankify this
  • Not Synchronizität, Synchronität. (at least in Schaltungstechnik).

Day 14. DT

Reading

Taskwarrior

Added never-ending tasks like cleaning as the first numbers, so I can still track the time. To give them ids 1 and 2 etc., I moved them to the top of ~/.task/pending.data. I might consider making a patch so that it’s less of ahack? Or – even better – just scripts that interface with timewarrior with taskwarrior out of the picture completely?

Jupyter/markdown

  • Bulletpoints are one asterisk
    • sub-bullet-points are +
* Bulletpoints are one asterisk
    * sub-bullet-points are <tab>+*

Scratchbox/stack

  • I should make a better way to track repetitive tasks like cleaning with timewarrior. A bash script, prolly? Like track cl or sth similar.
  • Create a day when I go through the scratchbox and paste it somewhere - let’s make it to a particular page on this DTB, and let’s make it wednesday.
    • but ideally recheck it once a day
  • Add to my statusline on the big screen the output of timew for th ecurrent “Tracking”.
    • DONE
  • Add a zsh command to make it easier to create new Jekyll posts, with correctly formatted name and content. I’m surprised that I have not found anything similar, it’s prolly there, but I haven’t looked enough.
    • DONE!
  • Fix dates in all posts – the ones inside the header, not the name
    • DONE!
  • add tags for not-work and deep-work to Taskwarrior, to better track time for clean work and various cleaning/social/lunch/whatever stuff.
  • Calendar – add the symbols in a maximally configurable way instead of directly into tikz-kalender.cls
    • DONE ?
  • How does \ifdate work inside tikz calendar, it’s like a globally defined command? Interesting I didn’t get that before.

German

Day 13. DT; Bewerbungen.

Resume

Added the new experience I forgot to add; very glad I could keep it still one page long.

TODO: Possibly change the template to make it less hack-y.

DNB

Scratchbox/stack

  • T P.HP Find something to do with the Scratchbox at the end of each day? All three of them
  • T h.it Add my vim spellcheck files with my custom words also to my dotfiles repo.
  • T connect https://de.wikipedia.org/wiki/Lastprognose with its English article about Load Forecasting;
  • add aliases for zsh and basic taskwarrior tasks. t 123 start -> tws 123

Latex

\& istead of &, like with \%.

Vim

Decided to map my insert mode things to +whatever, started with this suboptimal way to insert the date: `imap d :put =strftime('%c')kJA`

Python

For progress bars:

from tqdm import tqdm
for i in tqdm(my_list):

Productivity

A match made in heaven. http://www.infinitelooper.com/ is my new favourite website.

Zsh

Added alias for anki-vim as av.


Day 12. DT; Finances

DT

Found these beautiful slides by some professor. It’s fascinating how the slides themselves are interactive.

Which by the way reminds me of MarkDeck, which allows to make presentations as code in whatever editor and which imo has a lot of potential for me. I’ll look through it later.

Scratchbox/stack

Add to Anki \wedge \vee and other latexy things I’ve used. Add to anki formulas without commentaries, which work both sides.

Check how can I transform O in Firefox to open in the same tab

Possibly add the Glossary COICOP numbers to anki?

Add “personal” anki deck where I’ll focus everything important but sensitive.

Finances

Money is, at its essence, that measure of a man’s choices. (As quoted here).

First of all, I’m gathering resources to do it all systematically. So far the plan is:

Think about which books to read, possible variants:

  • 4-hour-workweek
  • The book from Deutsche bank about investing.

At the same time, parallelly to the above:

  • Make finally a budget and stick to it
  • Save X $currency per month
  • Build the needed liquidity
  • At the same time start slowly investing into stocks

In general, for less actionable steps:

  • Look into diversifying income

In february maximally stick to a budget and learn finances.


Day 11.

DNB

I think I found a website to replace my old favourite one. Now brainscale.net will be my main DNB one.

Day 10. Latex phantoms.

Latex

Kept modifying my calendar and learning LaTex on the way.

Function with multiple arguments

Function with two arguments:

\newcommand*\RN@formatDayNbWithMod[2]{
    % and inside use #1 #2 as usual
}

Phantoms and phantoms in math

A phantom is a symbol which has the width/height/dephts of a symbol but doesn’t print it. I use it to keep my weekdays in the calendar aligned.

From here:

  • \hphantom (horizontal phantom) inserts an empty box that has zero height, zero depth, but the width of its argument.
  • \vphantom (vertical phantom) inserts an empty box that has the height and depth of the argument, but zero width.
  • \phantom inserts an empty box with the same dimensions (horizontal as well as vertical) as the argument.

To use it in math environment, I needed to put it inside another pair of {}s:

  \ifthenelse{\thepeName=0}
  {\RN@dayNbFont$#1^{\phantom{0}}$\hspace{50\RN@xunit}}
  {\RN@dayNbFont$#1^\arabic{peName}$\hspace{50\RN@xunit}}

And here’s a nice discussion about what does width/height/depth mean in Latex.

Commands inside commands

Use ##1 if #1 is taken by parent. See here. Needs to be done also when parent command does not take arguments!

\newcommand{\abc}[1]{joy, oh #1!%
  \newcommand{\ghi}[1]{gloom, oh ##1!}%
}

Simple math

Needed to increase weeday by one, so that 0 is Sun. From this SO answer. Here I also compared #3 to 6, so I get a 0 instead of a 7.

    \ifthenelse{\equal{#3}{6}}{\the\numexpr#3-6\relax}{\the\numexpr#3+1\relax}

Day 9. Shabbat

Read 200+ pages of “Zen and the Art of Motocycle Mainenance” and drew a nice picture. After that went to Leipzig.


Day 8. Getting ready for DT exam.

Cooking

Made Champignons in the oven. Take Champignons, add oil, salt and pepper (less than I thought I needed), and put at 200C for 30 minutes.

HTTP

For redirects, this works.

<script type="text/javascript">
    window.location = "http://google.com";
</script>

CLI

curl http://passwordedsite.com/secret -u USER or curl http://htaccesspasswordedsite.com/secret -u USER -p PASSWORD


Day 7. Getting ready for DT exam.

Getting ready for DT Exam. To add all the chapters to taskwarrior, I made a textfile with one todo point per line, and then

while read p; do 
    t add project:HS.dt.pr  "$p"
done <dt_plan 

(See this SO answer)

Anki

Installed anki-vim. anki-vim DECKNAME, it created cards in ~/.anki-vim/decs/DECKNAME, that can be imported later from Anki.

I added to vim:

" For anki-vim math equation latex
abbr nla [$][/$]<esc>hhhi
abbr nbr \overline{}<esc>i

I needed the “allow HTML in fields” option during import. Also I learned that \cdot whatever needs a space, \cdotwhatever gets parsed as one control sequence. Was that always like this?

The multiplicative dot it latex is \cdot, for the math tilda \sim works. For the crossed out Antivalenz thingy, \not\sim.

\bar{a} and \overline{a} look very similar, which one to use is a philosophical question. I liked the answer here:

Semantically, don’t use either. Use \conj, or \mean, or \variant or whatever the overline is meant to mean. Then in your preamble, do: \newcommand*\conj[1]{\bar{#1}} \newcommand*\mean[1]{\bar{#1}}

Then: Your document source becomes readable: you can determine the meaning right there and then. Your document becomes more flexible: if you decide to denote complex conjugation by a star instead you can simply redefine \conj without worrying about changing what \mean does. You can change from \bar to \overline on a whim and don’t have to make that crucial decision now.

I also liked:

“All problems in computer science can be solved by another level of indirection” – Mats Sep 11 ‘16 at 16:28

Lastly: overline seems semantically and mathematically more meaningful, bar works like “just another thing”, not for conjugation/whatever.

Linux

cat /proc/cpuinfo for basic info about the specs of a computer. Also opening videos in Telegram is a bad idea, especially HD ones, opening them from VLC from the download folder works much better. also dmidecode -t 17 looks better.


Day 6. Internship report, vim German spellcheck, and a lot of German language.

Kept working on my internship report, hopefully I’ll finish it today. % Also tried to clean up the code for the algotrading thingy to make it use much more pandas.

Latex

Comment in bibtex: no easy and compatible way to do it. (see this).
Page numbering:

\pagenumbering{arabic}

To insert a tilde (~): \textasciitilde

And in general:

I seem to have a problem remembering where the Umlauts are. I’ll fix this with Anki. Should’ve started doing it a long time ago.

Vim

yank word: yaw. (Not inner, the entire thing, with all eventual paretheses etc.)
Rechschreibung: pacman -S vim-spell-de, after this :setlocal spell spelllang=de_de
Here are the important commands.

]s Gehe zum nächsten falschen Wort
[s Gehe zum vorherigen falschen Wort
zg Fügt das Wort unter dem Cursor dem Wörterbuch hinzu, das in der Variable spellfile steht.
zw Fügt das Wort als falsch der Wörterbuchdatei aus der spellfile-Variable hinzu
z= Bietet eine Auswahl von Korrekturvorschlägen an \

I added: map zr z=1<CR>, so now zr replaces the word under cursor with the first variant suggested. I love vim for the ability to do this.

Latex

Picture with caption:

\captionsetup[figure]{labelfont={bf},name={Bild.},font={small}, labelsep=period}

\includegraphics[width=0.45\textwidth]{data/lstm-1.png}
\caption{One-point-ahead prediction mit zwei LSTMs.}
\end{figure}

Day 5. PB+Latex

Kept working on my internship report.

Latex

for the % symbol: \% To use a simplier citation style, \bibliographystyle{unsrt}. For this I had to remove the package apacite. For using urls with underscores in Bibtex: \usepackage{hyperref}, and then howpublished = {\url{https://scikit-learn.org/stable/modules/outlier_detection.html}} for some reason worked for me, even though it shouldn’t have.

German

Day 4. Keyboard layout, Praktikumsbericht, Latex

Quotes

Fish don’t know they are in water

Keyboard layout

Realized that my Pchr8board layout uses only left alt as mod key, right alt stays as Alt and can be used for typical nice Alt-things like switching windows in tmux. TODO – still need to fix the tick. Or in the ideal world actually have one clean layout for two hands, one clean for one hand, separate Russian/Ukrainian ones and some kind of indicator, like the old one I wrote and forgot about.

Praktikumsbericht

Mostly writing my internship report.

Vim

Food

Made humus, following this basically recipe:https://www.bodybuilding.com/recipes/traditional-hummus. Next comes either bodybilder’s hummus or pesto hummus.

Reading

Rereading “Your rainforest mind”, reading “The Rime of the Ancient Mariner”.

Algo trading

Researched viability of it all, and got the impression that it doesn’t really make sense for me to get into it and that there are better ways to spend my time. Keep looking for ideas for other (but similar!) places where I can apply some of the approaches.

  • would it make sense to focus on individual stocks that can be directly connected to something external, that can both be analyzed?
  • can I find some more or less periodical stocs?
  • Can I find stocks which more-or-less correlate with something external and easy to analyse?

Day 2. Mediawiki + Praktikumsbericht - Tmux, urxvt, zsh

Today at the beginning I set mediawiki up, another one, and talked to M re everything connected with it. Now I’m doing my internship report.

For this I had to install latex, the package is texlive-most, which amongst other things contains xelatex.

Mimetypes

Install perl-file-mimeinfo. After this, I could change the program to use as mimetype what.pdf.

Tmux

I’m learning to use tmux, just because why not. I hear it’s better than screen. (And lighter than my current solution of multiple terminator instances.).

Best and greates tmux.conf

<C-b> d from inside tmux to detact the current session; tmux attach-session -t tb for attaching the session tb, also works with numbers. Can be tab-completed.

Urxvt

Middle mouse button for pasting from primary, Ctrl+Meta(Alt?)+C/V for copypasting from clipboard. Uses .Xresources for config, and I’m using this one, it’s perfect.

Jekyll

Added a Categories page, using this guide.

Zsh prompt

Added the mod system from my calendar to my prompt, so I can see if the day divides cleanly by 3 5 10.

DAY=$(date +%j)
r=""
w=""
x=""

if (($DAY%3 == 0)); 
then r=1
fi
if (($DAY%5 == 0)); 
then w=2
fi
if (($DAY%10 == 0)); 
then x=5
fi

PROMPT="$SPRINT ["$r$w$x"] $addprompt $PROMPT"

which gives me a prompt like: 2 [1] !!! sh•~/hs/dt» first number is the sprint number, in square brackets are the mod bits, then number of unfinished taskwarrior tasks.

Used this bash conditionals primer as reference.


Day 1. Finishing up installation

That was harder than expected. Sadly couldn’t document it as I was doing it.

Audio – install pulse, use it as a default device, otherwise ALSA will have problems playing sounds at the same time. Additionally, devices are hard. HDMI seems to be my new default device, changed that in /etc/asound.conf. I’m not even sure what exactly of what I did helped at this point, sadly.

pcm.!default {
    type plug
    slave.pcm {
        @func getenv
        vars [ ALSAPCM ]
        #default "hw:Generic"
        default "pulse"
    }
}
  • Moved i3 configs to .i3/
  • Needed to install gvim so that I’d have access to the system clipboard from vim.
  • Needed to add $HOME/.gem/ruby/2.5.0/bin' to my $PATH` in .zsh

Telegram adds a .desktop file after the first run based on where it is, so I had to change ~/.local/share/applications/telegramdesktop.desktop the lines TryExec and Exec.

Anki

Ankiweb extension: for Anki, AnkiConnect is needed, code 2055492159 + restart. It also seems to have it’s files not in .config like normal people, but .local/share/Anki[2]; copying them didn’t help to save the profiles. Ankiweb sync did.


Day 0. Jekyll

Well, first of all, today I installed Jekyll and started writing this DTB :) I’ll be using the minimal vanilla theme, I don’t think I’ll need much more. This will be backed up in github, and in general I think it’s a win/win thing on all possible fronts.

Also today I’ll be reinstalling my Arch Linux, from a working arch Linux installation. I’ll be documenting here the process so I won’t have to google it for the third time later.

I’ll also (finally!) fix the following:

  • fix all my configs so that they are optimal and readable
    • especially the vim and i3 configs!
  • better keyboard layout with explicit ru/ua thing to make my life easier.
  • make the zsh statusbar count my taskwarrior todos by better tags. I’m currently using this excellent approach.

As I’m also learning Markdown, I’ll be using this as a reference.

Installing Arch from an existing installation

I needed to install arch-install-scripts; after this I mounted the filesystems and followed the Arch wiki pacstrap gethsemane_root base base-devel

After that, just the wiki without too many changes.
