I build things with AI, then actually run them and measure before I write about them. Every number below was measured, not estimated.
Windows × Japanese locale is my daily environment. A lot of what I find comes from there — it is the setup most tooling is never tested against.
lp-section-studio — 880 production-ready UI components.
- 397 of them work as plain HTML — no React, no Babel, no build step. Paste them into PHP, Rails, Hugo, WordPress, or a bare
.htmlfile. - An MCP server is included, so AI coding agents can search and pull components on their own.
- 2,661 automated tests run on every change. axe-core: 881 checks, 0 violations.
- Live demo
stickman-video-director — a Claude Code skill that turns a Japanese idea into a complete stickman video package: 6-scene structure, English narration with back-translation, per-scene generation prompts, SRT subtitles.
CP932 swallows the byte right after Japanese text — but only if that byte is 0x40 or higher.
I ran all 545 Japanese characters × 95 ASCII characters. 63 symbols disappear (41.3–46.2% of the time); 32 never do. \ { } vanish, while " and ' never do — which is exactly why the failure surfaces as an unmatched brace on an unrelated line and you never suspect the encoding. With a BOM: 0 broken out of 545.
- Monilit — browser video player. 6 panels, every audio track playing at once.
- BIRIKABE — browser puzzle game.
- X — @yoggydev — what I ran today, and what it actually measured.
- note (Japanese) — note.com/yoggydev — long form, with the numbers.
