Since September, we have been unable to publish because every URL under `PUT registry.npmjs.org/@trpc/` is being blocked by a @npmjs @Cloudflare WAF. You can even prove it locally, they've just wholesale blocked our npm scope. Support have not yet done anything to help.

Did you know that the install size for packages with native dependencies (vite, rolldown, sharp, ...) varies by platform? upm web now lets you resolve packages with different platform presets to preview their install size.

`isolated-function` runs untrusted JavaScript in a sandbox. Some nice upgrades just landed: → sandboxed code can call functions you choose to expose → dependencies install via upm by @_pi0_ → a helper to wrap any step and get high-resolution timing Repeat builds are now 40x faster: 119ms → 3ms ⚡

My dev systems are back in my homelab. Latency from Japan to NL is ~260ms* Now is BEST time to improve my workspace client (pspace) for high latency. ==> First: supporting per message deflate in h3/crossws! (* theorical light speed is ~60ms i can't imagine how many network hops are between!!!)

One of the best pleasant moments using @claudeai models: they natively know about @unjsio libs and their design.

Dammit it even knows about all history 🫠 Maybe that's why I usually don't feel the need for many skills. It's already baked into the models for us 😅
