All in no particular order.

Projects - IT

My Bachelor’s thesis (2019)¹ was about native language identification in tweets, that is, given an English-language tweet written by a non-native English speaker, detect their first (native) language. Before it, my KPI Bachelor’s thesis was about using Shamir’s Secret Sharing to hide information in whitespace of multiple HTML pages (and using a browser extension to browse enough pages to recover the hidden data).

Otherwise I did more IT stuff than I can remember, mostly to solve problems I myself had (such as a mirrored left-hand Dvorak keyboard layout), some completely random (like a picture and quote generator that might still be up at http://reasonsforli.win).

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 only published paper.

Here are the (Russian) slides from a very informal privacy talk I once did, to a very lay audience, where I tried to explain why should they care about the topic at all; I once talked (in Russian) about Personal Knowledge Management on an awesome podcast: Data Coffee — подкаст о данных в современном мире.

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.

From time to time I wrote stuff, sometimes I wrote poetry, sometimes I translated poetry. I also like drawing (pencil and especially vector graphics with Inkscape).
