I've been thinking about concurrency and distributed messaging system for a while now. I started tinkering with various aspects of ZeroMQ, then explored designs and protype-implementation of a QUIC-based message protocol (like an alternative to NATS and similar). Hit some roadblocks and went back into thinking about concurrency and async I/O.

Then after a few pivots I landed on a good design for a framework which embodies what I'd like to see about programming concurrent systems without the gotchas of today's primisitives (e.g. callbacks/promise hell).

So I recently open sourced it (https://github.com/pmbanugo/tina). It's a high-throughput concurrency framework that bridges the Erlang-style concurrency with native performance (no VM, no GC).

One other area I'm interested in is formal method design using TLA (by Lamport). But I'm still scratching the surface on that one.

Tinkering around building https://viberglass.io. It started off as a way to allow my wife to keep her website up to date without any coding skills, but ended up growing arms and legs.

It is a hosted ticketing system/agent harness platform with integrations towards other ticket systems and chat apps. It allows triggering agentic (coding) tasks without the need to context switch and/or know anything about installing the wanted tools, SDKs, IDEs etc. Ephemeral workloads in isolated containers or cloud compute. Trying to help commoditize small scale development tasks and and prevent them from getting lost in the void of the backlog.

Open source with local or AWS self-hosted, full IaC attached.

A terminal manager for Claude Code: https://github.com/gi11es/deckard

The main goal is to reduce cognitive load managing many Claude Code and terminal sessions in parallel, while keeping things simple with a design focused on peripheral awareness of session status. And making everything resumable. The Claude session explorer also supports forking past sessions mid-conversation.

Overall this is designed to support the Claude-first software development workflows I've developed over the past year.

I'm building a financial censorship monitor at https://nofunds.org/, that tells a story of how money has been turned into a political weapon to silence journalists, activists, and civil society by freezing assets, blocking accounts, sanctioning, and banning payments. It's part of my master's thesis https://www.doria.fi/handle/10024/187407 and also https://news.ycombinator.com/item?id=36430596, but now I wanted to make a more comprehensive list, using Claude API and manual work. I'm designing a website right now, and the site is live within 2 months (given the API rate limitations currently to process articles). I know Hacker News is quite critical of Bitcoin, but it's also worthy to warn that, indeed, Bitcoin is at least a marginal tool to those whose bank accounts may be endangered. I'm basically arguing that Bitcoin can be used to resist such financial censorship, deplatforming and so on.

I am working on Tuumik - self hosted time tracking and in/out board. The project initially targeted law firms specifically (I was an attorney for a decade before coming back to software development). But Tuumik is suitable for any team working remotely.

Demo in browser (no registration required, just jump straight in): https://demo.tuumik.com/start-demo

If any HN reader wants to give it a spin, hit me up at support at tuumik.com.

It's not very impressive, but I decided I wanted to get better at recognizing NHL jersey numbers and was frustrated with the options available to learn (out of date Sporcle quizs and the like), so I tossed together a flashcard game with the help of Claude.

It pulls data directly from the NHL to stay up-to-date with changes to the roster, but is otherwise a pretty straight-forward and basic sveltekit app.

I've toyed with using AI for stuff like this (my day job isn't coding related), and this was consistent with previous experiences where I found it helpful in some respects (especially all the css and stuff which I don't really know too well), but it could also get stuck and produce some awful messes trying to fix it. I pulled this together mostly over the course of a couple hours, though, which definitely wouldn't have happened if I did it from scratch.
