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, ...).
  • Pchr8board, formerly known as Left-hand Mirrorboard layout for Dvorak - a layout for typing with the left hand on a Dvorak keyboard, using Randal Munroe's "Mirrorboard" idea.
  • 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. Currently working on an updated implementation without the Django backend.
  • Semantic Mediawiki Bookmarklets - some javascripts and Mediawiki templates that I use to add links to my links wiki.
