Штурм бар’єра 4 КБ: вебсервер у 4 092 байти на асемблері та окрема реалізація на nolibc C
Іван Сварковський розповідає, як умістив HTTP-сервер для роздачі статики у 4 092 байти асемблера MIPS і створив окрему реалізацію на C без libc. У статті — прийоми sizecoding, захист від обходу шляхів через симлінки, пастки ядра Linux та заміри на реальному роутері.

Making my 1KB ray tracer fast broke the byte budget 🙀
Five redundant ; before } saved 3 packed bytes: 1027 → 1024 B.
I tested 1024 ways to reorder the same math, like b[2]*s → s*b[2]. JSCrush saved 1 more byte.
1023 / 1024 B. Watch it render ↓

Had the interview for the professor position today.
I got asked what controllers I've coded for. After listing them I started talking about assembler sizecoding...
...I don't think the interviewer expected that.

Frank and I covered a lot in this, from his Midway work on Psi-Ops, to LittleJS, 13KB games and AI.
The big lesson is to make projects smaller, share along the way, and finish them.
