Git at Scale (by cursor) has been one of the most interesting blog posts i've read in a while. It came right when I was frustrated with Shopify's internal git system. As an exercise, I've implemented it over the weekend as open source. It's a single rust binary that you can point at any S3 type object store. It uses WAL and CAS primitives and requires no other data store. It also implements bundle-uri so large git repos (like our mono) are very fast to download as a chain of static bundles. Also comes with basic familiar UX. github.com/tobi/walgit

What if a signal on the server could just be a signal on the client? Wrote about @_developit's mixed-signals - it reflects server-side Preact Signals to clients over any transport. Write your state once as a model, decide where it runs. No fetch glue. No cache invalidation. Just signals. jovidecroock.com/blog/mixed-…

Bridging the Server-Client Boundary with Signals

How mixed-signals turns server-side Preact Signals into real-time shared state across clients, and what that can look like in tech like Cloudflare Durable Objects

Has anyone else noticed mobile frontends (native and web) are getting increasingly terrible (as we descend into UX vibe coding?)? I keep noticing I've developed ridiculous coping strategies like constantly copying input to clipboard in case it gets lost when sending.

Figured I'd open source the little preact+signals mastodon client I wrote a few years ago, in case the code is useful to folks. It's called Mastodawn.com - a streaming, offline-first installable Mastodon web app that weighs under 100kb. github.com/developit/mastoda…

npm's package name similarity validation for new packages is fucking ridiculous and should be killed

the fact that you can't even check similarity without fully publishing is absurd.

Moltbot is cool, but this would all be a million times cooler if it was TRULY LOCAL, rather than a tip of local sitting on an iceberg of hosted inference

Trying something new, we were working on a signals devtools extension but why limit ourselves to a browser extension? github.com/preactjs/signals/… - we're splitting it up and allowing you to render it anywhere with the proper adapter

This creates an independent set of packages including an adapter and ui so that we have all the moving parts for our chrome-extension as well as running it standalone in a browser/iframe/... Closes...
