Things I have finished, abandoned or am working on right now.

  • Gesturehand (my research paper as presented at FedCSIS 2017) - a shorthand system and a framework for creating symbols and alphabets according to given criteria and medium (touchpads, joysticks, eye-tracking, ...). Working right now on an implementation.
  • Left-hand Mirrorboard layout for Dvorak - a layout for typing with the left hand on a Dvorak keyboard, based on Randal Munroe's "Mirrorboard"
  • Tharmas -- my Bachelor's thesis. An algorithm, a set of Python scripts, a server in Django and a WebExtension for Firefox for steganographically hiding small texts in HTML-pages using empty lines, using PRNGs and Shamir's secret sharing algorithm.
  • Semantic Mediawiki Bookmarklets - some javascripts and Mediawiki templates that I use to add links to my links wiki.
Various / other
  • http://reasonsforli.win/ - random pictures from my "Saved" folder and random quotes from my "~/n/quotes" file. Sometimes it gives nice combinations. The most postmodernistic of all of them. Here's a glitch version.. Here are some nice combinations.
  • SparkSara - someday, it's going to be a website with tools for creativity, for now it's random chaotic pictures and random links from the wiki.
