I'm working on a man in the middle proxy for BGP, which can fix and inspect routing sessions on the fly. Like a firewall for the BGP control plane.

Some time ago I was building a mitm proxy myself, then I found out about: https://www.mitmproxy.org/ Maybe you already had it in your radar

That's for HTTP/S and related, as parent said his is for BGP which is a completely different protocol

Recently launched my free app for gardeners to share plants with each other, Plantshare.

Now I'm working on a few changes to the app, most notable is moving any plants marked as 'for sale' out from the main section because it turns out people are more greedy than I anticipated and it's getting in the way of sharing the free stuff, cuttings etc.

There's also some demand for a web front end so I might work on that next. (currently only android and ios)

I had an initial boom of downloads in South Africa but lately most new downloads are in USA.

I’ve been reverse-engineering an obscure childhood game called Entomorph:

https://github.com/entomorph/reverse-engineering

I started the project when ChatGPT 4 was first released, using it as a way to explore what LLMs could actually do. I also find working on it very relaxing, there is something cool about uncovering secrets hidden in code for more than twenty years.

A web app for my music needs - metronome, ABC notation editor with MIDI playback and PDF render, an embedded YouTube video player with a chapter/section creator based on timestamps and a looping feature for the chapters for practicing

https://metro.scopecreeplabs.com

https://metro.scopecreeplabs.com/abc

https://metro.scopecreeplabs.com/video

Offline first, everything is saved to Local Storage. Sharing is also purely serverless - the ABC text and the video chapter defs are shared via query parameters after compression and base64 encoding.

Tech: React, Material UI, ToneJS, ABCJS, CloudFlare (Pages, Workers, D1 Storage)

Next: Add an AI assistant to the ABC editor - editing ABC text gets painful fast.

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/

Building an MCP Gateway: https://www.gatana.ai/

Idea came from one of my clients, where they wanted to use AI agents throughout the organization but at that moment there was no centralized governance or security concepts. This pulls everything at one place and tries to solve the security concept with per-user credentials, which can be provided out-of-band through the MCP protocol (generated a one-time link end-user can use to sign in to the underlying MCP server with OAuth or provide API key)

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.

Ugh. It's time for me to start transitioning my iOS/Watch/Mac programs to be "Liquid Glass-native."

I should be able to do it with my various personal apps, but one app I've written, was done in concert with a professional graphic designer, and he is not happy with LG, so I expect that app to be a pain.

These are my apps: https://littlegreenviper.com/AppDocs/
