www.dolphinwhispers.com I working on the Android app to chat with dolphins using underwater whistles. The current version works well and is about to be used with free dolphins near Spain. We do not support captivity and we don't want our work to promote captivity or to increase revenues from captivity.

I'm working on https://www.numeromoney.com/pricing I don't even have the home page put together yet so marketing is still on the starting blocks! It's web app for helping to understand how you spend your money. I'm keeping it as simple as possible while trying to surface clear information about a persons spending. It came out of personal need (young families are expensive, it turns out!), and the existing products out there - YNAB etc were just too focused on budgeting. I just wanted to know where my money goes so I can focus on where I'm not spending it well.

At least in principle, I'm still working on PAPER (https://github.com/zahlman/paper). (Or I should say "resumed"; I was having a rough time of it mentally in the summer through October or so and didn't really get any actual coding done.)

This has most recently involved a side diversion into a little tree-processing library (where file hierarchies are a special case) — Show HN within the next day or two, fingers crossed — and setting up a fork of https://github.com/pypa/packaging to support EOL Python (back to 3.6) and make some general simplifications (because even this is a fairly large wheel compared to the target project size).

Hoping I can kick myself back into the blogging habit again soon, too.

I'm working on https://wireplug.org: A simple, free, and open source connectivity coordinator for WireGuard. Basically a way to keep WireGuard tunnels connected while moving between different access points. It handles (basic) NAT traversal and works with the in-kernel WireGuard driver on Linux and OpenBSD.

You can find the technical details at https://wireplug.org

1. Vibe coding a microcontroller firmware project. I'm using "vibe coding" in jest here because I'm actually an experienced coder, but this was a chance to try using the AI coding assistants for a clean sheet project at minimal risk. I'm going on 63, and could easily finish my career without AI, but where's the fun in that?

One amusing thing I've noticed is that every time the AI generates code with a hard coded hexadecimal constant, it's a hallucination. My son suggested feeding all of the chip datasheets into the AI and see if the constants improve.

2. Finally converting my home semi-hobby electronics business (something like a guitar effects pedal) to machine assembled circuit boards.
