What are you working on (August 2025)?

I've been hacking around with LLMs for close to two years. Finally decided to pull all the ideas into one solid thing, so currently working on something I guess I'd call an "Application Suite" of tiny apps using LLM inference one way or another, packaged into one binary/chrome/wrapper for controlling the entire thing, together with dynamically loaded (capability-gated) WASM Components and some other niceties. Don't have anything to share publicly yet, but excited none the less :)

- Sharing my latest blog post on various socials to gather feedback - it's about the problems with pinning GitHub Actions by commit hashes: https://developerwithacat.com/blog/202508/github-actions-com...

- Casually investigating a construction tech startup idea with an architect

- thinking of what to do long term. Feeling pretty lost at the moment.

I'm building Concert Map [1], an interactive map of live music events all over the world.

I was frustrated with how difficult it was to find concerts and festivals when travel plans are flexible. Questions like:

- Is there any show I could catch on my next cross country road trip?

- I want an excuse to visit Seattle this summer, is there a good weekend I could pick where I could see live music there or along the way?

- I like to travel for one big music festival per year, is there a good match for me anywhere in the country, or abroad?

The idea behind concert map is to show all events on a map, and highlight the "most relevant" events for any area, so you can skim through the map and find events that are worth the travel. The "relevant" events depend on the view context. If you import your top artists, then the most relevant events are ones with artists that you listen to most. Otherwise, it's based on global artist popularity.

I'm currently working on integrating with more event providers, and working on loading performance. I've been using leaflet.js [2] which has worked great, but I'm experimenting with switching to supercluster [3].
