Home, on going work to get local Kubernetes dev env running as close to a production one as possible - ingress, external-dns, ACME CA, load balancer, Argo, registry, prom-operator etc., running entirely locally. Work, similar but in Docker Desktop on Windows and Mac.

Longer term personal aim is a self-hosting platform based on k8s with straight forward bootstrap, similar to Yunohost but k8s based.

I'm again toying around with the idea of building an ActivityPub Server built around the principles of RDF, JSON-LD and the Linked Data Platform. [0]

It can work already as a "Generic" ActivityPub server and it can be made to work with Client-to-Server API, but given that there are not mature clients for that, I am now in the middle of an exercise where I am taking the existing server and implementing Lemmy's and Mastodon's APIs based on top of it. Once I can get any Lemmy and a Mastodon client working, I will then start changing their own SDKs, and then I can replace calls from their application-specific APIs with direct calls to Linked Data server.

• I've never been satisfied with music players on iOS, so I'm making the definitive one. It works with every personal media server, in additional to local files and Apple Music libraries. It'll do some stuff that no music player has ever done.

• I open-sourced and released some iOS dev tooling I built for Claude Code that multiplied my personal coding productivity: https://news.ycombinator.com/item?id=46264591 Nobody cares yet, but it makes me feel good to share something cool.

I'm working on a way to make it super easy to create and share beautiful photo galleries that tell a story. Take your folders with photos and create a web gallery that works great on all devices.

The project has a CLI interface that is free and open-source, but you have to self-host the gallery. We are also building a SaaS app which is basically a managed version of the open-source tool with a visual builder and we take care of the hosting and CDN.

I'm working on "Cargo but for C".

It started out as something marginally more useful than vendoring your dependencies as submodules + baking in the knowledge of how to build a bunch of common projects.

I realized, though, that there was somehow a huge gap in the insane world of C build tools. There's nothing that:

- Lets you pin really precisely and builds everything from source (i.e. no binary repository)

- Does not depend on either a scripting language or a completely insane DSL (Conan uses Python, CMake is an eldritch horror, ditto Make, lots of other tools of course but none of them quite hit the mark)

- Has a good balance of "builds are data" and "builds are code".

Anyway, it's going great. There are, of course, a ton of problems to solve. Chief among them is the obvious caveat that C is not a monoculture like Rust. There will be zero upstream libraries that use this tool natively. But I don't think it matters. I think I can build something which is as much better to the existing tools as, say, UV was to existing Python tools, even with that disadvantage.
