Articles on systems programming, C, Linux, memory management, and multi-agent architecture.

6 posts RSS

Articles on what doesn’t change. Systems programming, C, Linux, memory management, multi-agent architecture. No throwaway tutorials, no clickbait — each piece takes the time to explain why, not just how.

Writing takes time. Publication is not regular. But each article is worked until it says what it needs to say — not a word more.

Introducing bit-crafts: a C11 monorepo for fast file inspection on Linux
May 9, 2026 8 min read
6 libraries, 3 tools, one C11 monorepo: bcduplicate finds duplicates at 758k files/s — 18× faster than rmlint on the same thread count.
AI at work: what I built while everyone was debating
April 22, 2026 11 min read
82 % of developers use an AI weekly. A randomized study measured −19 % productivity on experienced devs. 80 % of companies see no gain. Six C libraries, four CLI tools, and a full intranet — built in four months for $1,000 in AI usage. What actually worked, and what I still refuse to delegate.
parallel-walk-plus-process: the pattern behind bc-hash and bc-duplicate
April 21, 2026 12 min read
Why find | xargs -P plateaus at scale, and how three phases separated by a strict barrier — parallel walk, sequential merge, parallel process — take a recursive hash from 12s to 7s on 650k files.
bc-duplicate: three passes to find duplicates without reading 99 % of the files
April 19, 2026 6 min read
Find duplicates among a million files in 3.7 seconds: a size → fast-hash → full-hash pipeline, io_uring, and adaptive dispatch. Numbers, architecture, and what the hash choice actually changes.
brk, sbrk, mmap: what malloc hides
March 17, 2026 4 min read
malloc calls brk for small allocations and mmap for large ones. What really happens under the hood, syscall by syscall.
The 4 allocators every C developer should know
March 10, 2026 6 min read
Bump, pool, free-list, arena — four C allocators to replace malloc where it counts. Principle, use case, and minimal code for each.
