Theme: AI lock-in skepticism + niche survival (Tsoding) and anti-bloat, anti-premature-optimization, know-why-not-guess craftsmanship (Blow). Note: most are short clips with auto-generated captions — phrasing approximate.

Tsoding

  1. How to fight evil AI companies (link)

    LLM-only metadata (llms.txt, agents.md) and bloated AI docs = deliberate vendor lock-in + compute rent-seeking. Round-tripping info through LLMs degrades signal like repeated JPEG compression. Fix: don't attack data centers — expose the tricks publicly so people stop playing along.
  2. How to survive as programmer in age of AI (link)

    Carve out small quality niches big "slop corpos" won't bother serving — they're slow and bloated. Example niche: fast performance software (File Pilot). Defend it.
  3. Trick to measure code complexity (link)

    Count semicolons, not lines. In C-like langs each semicolon ≈ one statement; line count distorts via multi-line formatting. Wren VM "under 4,000 semicolons." Good-enough proxy.
  4. Why he doesn't work on Operating Systems (link)

    Not difficulty — format. OS dev = long multi-stream project, but episode 1 gets 1000+ viewers then everyone drops off. Needs self-contained stream-sized hook (idea: "GS kernel" booting to a REPL).
  5. Why he doesn't use Odin (link)

    Tongue-in-cheek: scared of the creator, who jumps into chat to aggressively defend Odin on any criticism. Never tried it; "good language" hedge.
  6. Why he doesn't have a job (link)

    Money stops motivating once basic needs met. Pre-streaming: freelance gig → save → live off savings. Took office job once; frugal probation salary lasted 6 months, then walked when offered permanent.
  7. Bun's rewrite from Zig to Rust (link)

    Rant: rewrite added ~300k lines, Bun now +1M lines. A JS-engine wrapper 3x the size of a full game engine (The Sinking City, +300k). "Literal insanity."

Jonathan Blow

  1. Fought John Romero over DOOM's asset loading (link)

    As a student, raged that DOOM's linear-scan asset lookup should've been a hash table. Romero defended it. Blow now admits he was wrong — profiling showed lookup time negligible; hash table costs more memory/fragmentation/bugs. Use array of records; optimize only on real need. Lesson: when skilled people build something that looks wrong, assume you don't understand why.
  2. Why code size should be small (link)

    Bloat self-reinforces: as code grows, understanding erodes → devs add instead of refactor → grows faster. Either spirals or freezes the project. Keep small deliberately, especially in legacy.
  3. How to finish projects (link)

    Used to start, never finish. Turning point: named the pattern, then past 30 confronted gap between self-image (does important things) and reality (hadn't). Decided to get serious.
  4. Why the Dragon Book is terrible (link)

    Rejects the classic compiler textbook flat — "terrible," learning from it makes you bad at compilers. Maybe OK in 1986, "not even then." Calls universal university assignment "an ethical breach."
  5. How web programmers solve problems (link)

    Mocks guess-and-check: throw "stupid things at the wall," keep what works. His philosophy: "We want to know the correct answer... what is right."
  6. Disables Microsoft Defender, huge speed-up (link)

    Operation 14s with Defender → ~5s without (≈3x). Offended Windows won't let him permanently disable it. Preempts "you're using it wrong" pushback.
  7. On parallel programming (link)

'90s parallelism techniques were already what's "good" today. Post-'90s "magical" auto-parallelism is worse — a regression masked by decline in programmer expertise. Today's parallelism = '90s tech dressed up as new.

Eskil Steenberg

  1. Why he doesn't use version control | BSC 2025 (link).

    No git — "never gave me anything." Single flat source dir, strict naming so a function's prefix tells its file. Never deletes; wraps dead code in #ifdef DEPRECATED. Occasional dated snapshots, never goes back. Team = independent "library releases," teammates adopt or ignore. "Born C, always C."
