Revived my father's restaurant/hotel's website with astro, using cursor. Hooked lingui to it to translate to 3 languages, then added automatic OG image preview generation. Was more fun than I expected! Will share how I did it in my blog soon, but until then, take a look: theresahotelcyprus.com

Asked Opus 4.5 to make a marketing video for my OSS project, [@]firtoz/router-toolkit. It wrote the script, generated voiceover + word-level timing (@elevenlabs.io), created the logo (Nano Banana), built animated scenes with Remotion. All in one chat session. What do you think?

As a result, we ask it to respond with a xml tag and write the code inside. Luckily that was easy enough to generate and parse. Pass that through the sanitizer, run it, then return any logs and error back to Claude, and there you have an agent!

It uses } instead of `end`, tries to do ternaries and inline accessors etc. Hopefully in the future it will improve so we won't need a Lua sanitizer. There are other options e.g. fine tuning some models but we don't have enough samples for training.

Currently it can create primitives and group objects, all with Lua. However this is not with a tool call, it's with xml in the response text stream. This is because of you have a giant string in a tool call parameter Claude will not stream it, and if you run out of tokens, RIP

Now the details: we have primitives such as cube, sphere, cylinder, etc. First we tried to use one tool call for each shape which allows it to build things incrementally but there's a lot of token wastage and it takes much longer. So we needed to do something better.

firtoz
@firtoz.com

The better thing: scripting. But which script? JavaScript felt unsafe, python didn't feel right, so we went with Lua. It works well most of the time but it's not perfect. So we had to write a "lua sanitizer". Most of the mistakes Claude makes are because it tries to write JS.

Wow it was much more effort than necessary to be able to do offline capable local first web app development, but I'm happy to say that I found a way - see thread:

Then, for offline mode, you need to set up service workers, which is another can of worms in itself. And then, while you're caching files from the service worker, you need to make sure that it will do it in a way to enable the magic headers mentioned in the previous post.

I'm sure others figured this out too but for my use case - using the same drizzle schema for both server and client, and enabling offline mode, that's what I needed to solve. If anyone is interesting in diving deeper into anything about this, happy to chat.

1st, for the database, you can use local storage for small amounts of data and indexeddb for larger, and also origin private file system (OPFS) for more beefy stuff, e.g. for sqlite wasm you use this. However, OPFS has requirements for magic headers: web.dev/articles/cro...

Managed to get the same @drizzle.team schema work for both Durable Objects and sqlite for web workers persisting through OPFS, for #lofi . Very excited about it! Did anyone do something like this before? Would love to get some inspiration etc.

Teasing a live two way sync between @unity.com and @threejs.org, would be curious to hear thoughts on it! It works also between multiple unity computers or multiple web views. For collaboration in level creation etc. Integrating into @greybox.app soon. #threejs #leveldesign #gamedev

The idea is that you should be able to share the web view instantly with a client or the team so they can see the scene or the game without having to open the engine, do a git pull, etc. Or replace git or Collab entirely, who knows. Let us know your thoughts please!

Took me surprisingly little amount of effort to migrate from a centralized postgres db to Durable Object sqlite 🤔 I think most credits go to @drizzle.team for this. Next: LOFI through pglite + indexedDB?

If TikTok does get blocked in the US, millions will try to skirt the ban by using VPNs that route their data through another country. But many VPNs are hella shady! Here's @shiraovide.bsky.social with four VPNs you can probably, hopefully, quite possibly trust: www.washingtonpost.com/technology/2...

I'm experimenting with some react three fiber with #threejs webGPU. We don't have an EffectComposer to use post-processing effects in #r3f with WebGPU API. Now, everything is done by composing TSL nodes. I created a small component that helps in rendering post-processing effects...

When you have a bunch of durable object instances, how do you keep track of them? Should they ping a manager DO or something which keeps track? #cloudflare
