My writingI've got a blog. I also sometimes write educational material in my Telegram channel (in Russian). Other stuff:

Analysis of polynomial hashing, Kapun's algorithm (2022) — A syllabus on various commonly used rolling hash techniques (in English)
Additional chapters of physics (2022) — Introduction to thermodynamics (in Russian) and a bit of special relativity (in English)
Lambda calculus (2022) — Introduction to lambda calculus (in Russian)

TriviaI'm a former gifted kid who developed lots of projects in no time, but these days I'm suffering from ADHD. I used to suffer from depression, but I'm okay now. That was an interesting experience for sure.

I love inventing new stuff, which often turns out to be well-known, which in turn devastates me for days. Oopsie.

I love listening to BMTH, Badflower, and LukHash.

My favorite book is Worm (no, seriously, give it a read). My favorite modern-day author is qntm. Actually, I have a TODO list for literature pieces ~~(I have yet to read faster than it grows)~~.

My favorite color is #8f1fff.

Celeste helped me at a low point in my life, and I promptly forgot about it afterwards. I still haven't completed The Summit.

I don't like custom set ups, mostly because I don't have any time for that. ~~I'm still using the same Ubuntu I set up years ago as an experiment to see if I can get myself to switch to Linux.~~ I use Arch now btw. Linux turned out to be garbage, but every other mainstream OS is even worse, so perhaps I'm stuck with it.

I'm still looking for a programming language with memory management capabilities of Rust, low-level control of C, performance of assembly, control flow guarantees of Agda, and typing system of F*.

Apart from programming, I'm interested in algebra, topology, physics, and my girlfriends.

I'm nostalgic over the good old days I've never seen and love retrocomputing.

$ cat test.c
main(){main();}

$ gcc test.c
test.c:1:1: warning: return type defaults to...

$ ./a.out
Segmentation fault (core dumped)

$ gdb ./a.out
GNU gdb (Ubuntu 13.1-2ubuntu2) 13.1
...

My stackI'm familiar with:

Frontend: basics (HTML/CSS/JS), TypeScript, Vue, React (and Next.js), Webpack et al.
Backend: Flask (i.e. Python), Rocket (i.e. Rust), Express (i.e. JS), good old PHP
Sysadmin: mostly Linux, basic systemd, nginx, httpd stuff
Systems programming: C/C++, Rust (including embdedded), Python, a bit of Go
Low-level: Linux kernel & modules, x86 assembly and optimization, a bit of compiler internals
High-performance computing: nothing to note in particular, just an unhealthy dose of attachment to performance and experience optimising code for x86
Algorithms & data structures: programming competitions and still continuing bachelor's program
Networking: basics and experience with ZeroNet
Information security: mostly CTFs and high security projects
Open-source: contributed to a few projects and released lots of my own

This isn't much, but ~~it's honest work~~ I'm open to learning more.

My main area of interest is systems programming, cryptography, HPC, and system administration. See kitchen sink for some of my projects on these topics.
