I'm working on a project for deploying containerized workloads across your own servers, but with great dx from starting on a $5 server to migrating/scaling to 200 servers (no downtime required for any migrations). think coolify, but with railway dx and no single server limitations.

there's no control plane, each node is equal and eventually consistant and its (so far) end to end rust so a very minimal footprint per node.

I'm building open source homebrewing (as in beer) software at https://www.brewdio.beer. It's something I've poked at periodically for a few years but now I'm using AI to see how far I can take it.

It has a few core libraries built in rust with a web app and a terminal UI. Android app is in the works. The persistence layer is intended to be offline first using a CRDT with an optional sync server. I'm also trying to integrate "bring your own AI" assistants to help tweak recipes or make suggestions.

It's been a fun way to sharpen my claude skills but also to see how feasible it is to maintain multiple frontend applications with a large amount of shared code. Still a lot to do, particularly the core calculations are not yet on par with existing offerings.

Spent the last year expanding my homelab and now I have my own rack at my local DC with my own ASN and /23 prefix.

Its been pretty fun cosplaying as an network engineer, and now I'm building out an Anycast network for a few ideas that I'm working on.

Its nothing too revolutionary or new, but I'm proud that I've built them from ground up and all running on my own infrastructure.

- DNS Authoritative Hosting - https://thelittlehost.com/dns/ - Quietnet - A family-focused internet filter - https://quietnet.app

I'm also getting ready to launch https://relaye.io, which was my personal tool I built to support my devops consultancy.

I'm trying to see how far I can get using AI to help me track pre-owned items for sale, starting with watches. I started with an OpenClaw agent that was looking for specific things I wanted to buy, and then I figured might as well make a whole site for it so I can share with others.

I've been working on a Ontario open data MCP: https://github.com/sprine/ontario-data-mcp

There is a wealth of data that's behind CSVs and other data formats. This uses DuckDB as a common (local) database to cache and run queries against, and enables going across datasets for insights using LLMs.

We are developing a single-passenger autonomous vehicle, capable of traveling over 1000 miles, performing fully automated vertical takeoff, cruise, and landing.

rainy-city.com! rainy-city.com is an ambient rain sound generator that is also a kind of city simulation. it is my recurse center project. it's suppose to be more of an ambient experience than a city simulator. it's a total work in progress, I've implemented buildings but haven't made a PR yet because they don't really work the way I want them to, and so I had to rebuild the tiling for them. So right now, there is no city. lol. just rain. but eventually it will have all this stuff you would expect. there are whales.

https://talimio.com/ Generate fully personalized courses from a prompt. Fully interactive.

New features shipped last month:

- Adaptive practice: LLM generates and grades questions in real-time, then uses Item Response Theory (IRT) to estimate your ability and schedule the optimal next question. Replaces flashcards; especially for math and topics where each question needs to be fresh even when covering the same concept. - Interactive math graphs (JSXGraph) that are gradable - Single-image Docker deployment for easy self-hosting

Open source: https://github.com/SamDc73/Talimio

Very cool! I'm chaperoning a python club for teens these days, I should make use of this concept!

i was delighted to see your comment at top... I am working on the exact same thing, generating concept DAGs from books and letting a tutor agent use it for structure and textbook reference. can we discuss this somewhere else?

Is this launched? Looks cool, but you should add a privacy policy.

It's -kind of- launched, still have couple of things to tight.

And will add a privacy policy by the end of the day, thank you for point that one out

I've been on sabbatical (not on leave from anywhere, just decided to take a break from work) for months now, taking some time for myself. Minimal tech stuff until more recently, but now I'm back in the deep end.

The main thing I'm currently working on is a platform for organizing and discovering in-person events. Still not certain about the boundaries for "Phase 1", but I have a bunch of ideas in that space that I've been incubating for a while. One subset of features will be roughly similar to that app you've probably heard of that starts with 'M' and ends with 'p', but hopefully an improvement, at least for the right audience. But wait, there's more. :)

Currently building it; it's not public yet, so no link. Next month.

Thinking about how to grow the userbase is intimidating, but I think it might end up being fun.

I’m working on uvmap.ai A browser tool for editing 3D model textures directly from the model view instead of bouncing between a UV map, an image editor, and an AI tool. You load a glTF, click the part you want to change, it uses SAM3 to mask that region, then sends it to Nano Banana and puts the result back onto the texture. Still early, but the goal is to make texture iteration much less tedious.

Soon here: https://github.com/RefactorHQ/UVMapAI
