I am Ukrainian. While Russian army invades Ukraine, kills, rapes, destructs, and steals, I am in Kharkiv, my homecity

I am almost useless but I am volunteering to help those in need, and I am staying.

UPD: I've joined Ukrainian Armed Forces in March 2023.

🇺🇦 HELP UKRAINE WIN 🇺🇦

Let the text below become relevant again in other times.

Developer and writer from Ukraine. Ruby programming language committer.

Mostly interested in lucid code and open data, and writing a Substack about it. The range of “my” topics are united by an urge to understand and explain. Or, the problems of knowledge acquiring (with code) and expressing meaning (with code).

Working on my first Ruby book, working title "41 Ruby Intuitions".

Recent/interesting work

Ruby programming language

• Contributions to the language (new features and docs)
• Ruby Changes: annotated changelog; writing about working on it: 1, 2, 3
