Other stuff

The work log on this website is the longest-running and actually most useful project, it makes my life much better and which hopefully helped some other people.

Otherwise I did a lot very random IT-adjacent stuff, mostly to solve problems I myself had (such as a mirrored left-hand Dvorak keyboard layout).

I once created a shorthand system, then tried to optimize it with genetic algorithms, then thought about how interesting would it be to think of an algorithm to generate alphabets based on requirements/medium/messages, which became my first published paper.

Here are the (Russian) slides from a very informal privacy talk I once did, to a very lay audience, about why should one care about privacy at all.

Projects - not IT.

From time to time I wrote stuff, sometimes I wrote poetry, sometimes I translated poetry.

I also like drawing (pencil and vector graphics).
