I'm writing an M68K NeXTStep userland emulator and thunks to run NeXTStep apps under GNUStep. I'm starting today with hello world.

#162Working on tsz (https://tsz.dev)
a performance-first TypeScript checker written in Rust. Started 5 months ago and it's been mostly AI-written code. 99.8% tsc conformance test pass rate today. Single file benchmarks are 3–5x faster than tsgo.

#163I'm trying to make it easier for non-technical folks to publish websites: https://weejur.com
82 sites published so far, with a really weird and wide range of content.
Working on a simple WYSIWYG website editor to go with the current functionality.

#166I've found it hard to keep up with movie and TV news (particularly when the new Backrooms film is coming out).
So, I built an agent to help remind me -- it's a subscription based service that sends you updates every morning, and stores your preferences so it can learn what you like.

#168Social Maps: a user reviews and ratings service for points-of-interest (e.g. cafes) in OpenStreetMap.
I’ve been trying to reduce and eliminate my reliance of the Big Tech and the lack of user reviews and ratings was always a big pain point for me each time I tried to switch away from Google Maps.
I’ve started building a service where users can write reviews and rate “places” (POIs) in OpenStreetMap database, such as a cafe, a museum, or a shop. It’s a quite straightforward CRUD app with bunch of OpenStreetMap-specific features such as logging in with OpenStreetMap and querying places by their OpenStreetMap metadata.
It’s still in active development but it has good docs, a great API reference (including an OpenAPI spec), a demo app with the entire planet imported and queryable, and an early stage Android SDK.

#169I'm working on a little local first review tool called Review (though I sometimes refer to it as differ since that's it's original name) - you can see screenshots here https://x.com/rhyslikepb/status/2053149881104265599?s=20
The idea was borne out of wanting to use the review tools that you get on existing sites like GitHub, without having to push and start bloating PR lists. You'll be able to leave yourself comments and code suggestions after review, which you can then pull out in a Markdown file to feed back to your coding agent (or anything else for that matter).
I'm also trying to include some optional (very optional) AI extras where you can use your own keys, and then get a tour of what you've changed and a quick overview of the changes.

#170I'm slowly but surely working on a first update to my Android app, Tunemark (https://tunemark.app), which I released a while ago. Tunemark lets you add bookmarks to moments in songs so that it is easy to jump back to them. It is really convenient when practicing dancing or music and you need to constantly reset back to specific parts of songs. Unlike most DJ-type apps that could serve similar use cases, Tunemark works with most music apps, including streaming services.
I have new features such as sharing bookmarks and possibly BPM detection planned but also some quality of life changes like better UI scalability for different size screens/split screen use.
