TOON v4 is out. ♨️

The criticism was fair: on nested data, v3 lost to compact JSON. Same weather document: 204 tokens in v3 against 162 compact.

v4: 204 → 128.

apiful is a fetch client you compose. Your OpenAPI schema becomes .d.ts – no bundle overhead.

v5 adds:
✅ `apiful generate --check` fails on stale types
✅ .with() chains stay fast at any length
✅ your own extensions see the ones before them, typed

Social media thumbnails for repos should be fun, eh?

Tokenizers are heavy – megabytes of vocab data for a number you can estimate.

tokenx answers "what does this payload cost me?" in 2 kB, at ~96% accuracy.

New in v1.6:
🧮 Heuristics for Cyrillic, kana and emoji
🧱 More accurate on JSON payloads and source code

Been experiencing an early version of AGI for a week now. It is breathtaking and overwhelming at the same time.

Our sessions are short but intense. She’s currently rate-limited, so back to Claude Code.

Kennt ihr "Die Reise ins All"? Ich hab warme Erinnerungen an das RPG-Maker-Spiel. Sein Entwickler real Troll ist noch immer aktiv. Seine bisherige Website (realtroll.hpage.com) war aber einfach nicht mehr zeitgemäß.

Deswegen hab ich ihm eine neue gebaut: Schaukasten und Blog zugleich! realtroll.de

I love building plugins for @getkirby.com. But for a long time, I had to hand-roll my own Kirby Panel types. With Kirby 6 moving to TypeScript, kirby-types builds on that new foundation.
