Working away at https://TempMailDetector.com , a privacy focused disposable email detection API which only requires the domain part and not the user part of the email. The service is able to determine if a domain is likely a disposable email, a forwarding service, and actively crawls for new domains.

What business is it of yours if someone uses a temporary email? You know Gmail is free right? You gonna block it too?

Still slowly working away on my location intelligence data union..

I’ve spent a while understanding what sort of market would make it viable. I think it does actually work if you can square: 10K participants per major metro area, revenue of about 2.9M per metro area (so say, 5K monthly recurring with about 50 customers).

At that point you could pay data union participants about $5 a week to share their location data with you.

From talking to some previous data union folks, the major challenges are paying out (my target is much higher than any union managed), and people dropping out over time.

My bet is that these are both solvable things by selling data products rather than just bundles of data, and the data source being very passive.

I’m also interested in the idea that such a union should act more like a union than previous efforts in this space, by actively defending members’ data from brokers.

I'm currently building my own coding agent, VT Code. VT Code is a Rust-based terminal coding agent with semantic code intelligence via Tree-sitter (parsers for Rust, Python, JavaScript/TypeScript, Go, Java) and ast-grep (structural pattern matching and refactoring). It supports multiple LLM providers: OpenAI, Anthropic, xAI, DeepSeek, Gemini, OpenRouter, Z.AI, Moonshot AI, all with automatic failover, prompt caching,…

You’ve done an incredible amount of work — I’m definitely going to try out the Zed integration. I’m curious though, how significant do you think it is for the agent to have semantic access through Tree-sitter? Also what model have you had the most success with ?

Kindly let me know how your experience about Zed integration, I have done the ACP integration and merge to upstream Agent Client Protocol spec from Zed. The integration experience is quite magical, honestly. It's working in Zed , though for tool calls I'm still improving https://github.com/agentclientprotocol/agent-client-protocol...

I've been working on a 3D voxel-based game engine for like 10 years in my spare time. The most recent big job has been to port the world gen and editor to the GPU, which has had some pretty cute knock-on effects. The most interesting is you can hot-reload the world gen shaders and out pop your changes on the screen, like a voxel version of shadertoy. https://github.com/scallyw4g/bonsai I also wrote a metaprogramming…

Looks great!

I am working on an AI-powered fitness and food tracker that automatically logs your food based on the photo. One of the difficulties I had when going to the gym is keeping up and sharing macros weekly with my personal trainer. Manually logging food is a hassle and massive pain point - so my app, Eat n Snap attempts to solve this problem. You can also set weight and BMI goals and see your progress on a weekly basis. S…

I think this is hard with only a photo because you can’t always see what’s inside. But I’ve always dreamed of something like this paired with some kind of affordable hardware scanner that can get just enough data to fill in the blanks from the photos.
