Working on a low cost, miniature Bluetooth tracker. The inspiration was my parents keep losing (forget) their spectacles in the house. I wanted to build something that is very easy and simple to use and it was important to keep it small. SO the form factor is something like an airtag but 10x smaller which can be just stuck on to the spectacles and forget that it exists. Next step, obviously is to build a simple app that shows the location of this tracker with a range based on the Bluetooth signal strength.

Made some updates to this open-source library I wrote to render audio waveforms using the GPU on the browser (WebGPU).

Example on the site. Works without enabling flags on Chromium browsers. There's an example to scrub and zoom in real time on some audio. Feedback welcome!

For fun have been creating a mashup of old school DnD map generation using Commodore "10 Print Chr$(205.5+Rnd(1)); : Goto 10" style logic (in TS/Svelte/SVG):

Have been down a rabbit hole ensuring the stairs are realistic and that grid connects properly. Lots of fun and frustration with AI coding tools trying to solve that (they mostly don't/can't). Some fun detours learning a little Prolog to help out as well.

I'm building a coding agent, named VT Code [0]. VT Code is a Rust-based terminal coding agent with semantic code intelligence via Tree-sitter. Supports multiple LLM providers with automatic failover and efficient context management. Support OpenAI, Anthropic, Google Gemini, xAI, DeepSeek, OpenRouter, Z.AI, Moonshot AI, MiniMax, and Ollama (local & Cloud). Agent Client Protocol and Model Context Protocol fully support. VT Code supports a rich set of configuration options, with preferences stored in vtcode.toml. Has both Visual Studio Code and Open VSX extensions so that you can install in VS Code or Cursor, Windsurf, Eclipse.

I've been building it for several months now and enjoy the learning process, I also wrote a blog post and learnt a ton about terminal, ANSI processing. The learning has been immense for me, I now have working knowledge of ANSI escape codes, grapheme clusters, terminal emulators, Unicode normalization, VT protocols, PTY sessions, and filesystem operations, all the low-level details I would have never think about until I were implementing them.

Highlighting the nftables rules. For Vim/NeoVim editor, using your own color scheme and background.

Like grouping statements together within a rule with heavier emphasis on keywords that starts each of its statement.

Even has the easiest Vim installer, `make install`/`make uninstall`; none of that funky Vundle, or other relatively unknown Vim packagers.

Has over 2,500 semantic nodes, 15,000 syntax match statements, and under 5ms rendering.

This is a purely deterministic LL(1) full semantic parser.

Skip the release (I cannot delete it), go full repo clone.

Is it ready? Yes, almost entirely, unless you are a firewall expert using few remaining nftables-supporting but esoteric features like ‘synproxy’. Gotta master that first before I can highlight it properly.

Finally started getting back into game programming and have been working with Lua and Love2D - been trying my best not to get bogged down in the weeds (eg how do I animate a 3d cube on a 2d plane?) and I’m focusing on learning how to actually work with the Love system and organize my code. I’m getting a crash course in jj as an added bonus!

Building an ai powered threats deception proxy.

It's a honeypot system that uses AI to mess with attackers. When someone tries to hack your app, it detects them and serves up fake responses based on attack type.

The system learns from attackers behavior and creates convincing decoys to waste their time and frustrate their efforts. It's basically a trap that gets smarter the more attackers poke at it.

Tired of having my notes spread everywhere, on uncomfortable software, I'm writing my own Notational Velocity desktop app clone in Godot:

https://share.combo.cc/-Z7hBzNbaCc

(work in progress prototype, design is not final)

Intentionally made simple and centered around plain text files and editing speed. I've spent a week on the prototype, now it's good enough to dog-food. Would like to eventually distribute it as a multi-platform app.

I’m working on a MUD server. I want text-based adventures.

Also... would it be crazy if services and social media were text-based applications too?

Not necessarily through telnet, but with some kind of standard so that instead of the web/browser, we use a CLI(s).

I dunno, maybe I’m just bored.

Recently I've been wanting to build a chat server that works over ssh. And by that I don't mean it uses the ssh protocol but that you ssh into the server and the shell you get is the chat client.

One day, maybe

I've been really frustrated with the state of networking and discovering new career opportunities lately. Both in person and online I feel like there aren't very good tools and I have a growing disdain for LinkedIn. I wanted to make a tool that helps ambitious navigate their career goals and meet people who are going to move the needle. It's called Catalyst: https://getcatalyst.tech/

Hey, how can I contact you privately?
