Updating my workout app with final touches. It’s local first, with self-hosted backup server as an option.
It’s text based, so it is basically an advanced editor/viewer for one long text note.

#122Over the holidays I was building a wooden birdhouse with a Unifi Protect camera and a small web interface that automatically identifies the birds and shows me a simple overview over which type of bird visited how many times.

#123Just got started again on my "Poor Man's Bitemporal Data System" (discussed here: https://news.ycombinator.com/item?id=45118585 ). Holidays nuked all the hot-cached context in my head. I spent a few days just spinning wheels until it repopulated. But the basic idea works now! Much testing and benchmarking work remains to make sure it's not going to lose data, and that it won't denial-of-service itself (because object…
Love the idea! Read only the beginning of the first "giant blog post" so maybe it's discussed there, but in Sqlite doesn't WAL mode give you a kind of super simple, super basic temporal data system? If you somehow kept all WAL entries 'as is', it should be possible to reconstruct the state of the db at any point in the past?

#124I have been porting over my favorite Erlang library "Bitcask" to Rust. https://git.sr.ht/~tombert/feocask Called "feocask" cuz feo means "ugly" in Spanish and FeO to mean Iron Oxide for Rust. I thought it was funny. I will admit that I had help from Codex, but I did write most of it myself, and I think the design is coming out kind of neat. I have a very strict "no lock" policy [1], including lockfiles, and this shou…
fyi the project appears to be private :)

AI models and open source robotics for food production.
From backyard gardening, subsistence farming, urban gardening, and other forms of small scale agriculture.
We believe no one owns nature and that all growers have 100% right to repair any equipment we offer.
Our first IOT device (greenbox) is in an open beta for 2026. Please reach out to support@gthumb.ai if interested.

#126Been hacking on https://rsolv.dev. It's a security scanner with a couple of unique twists; in addition to using AST validation to cut the false positive rate, it uses a heavily orchestrated LLM to write unit tests that fail if the detected vulnerability is present.
Happy for alpha users; it's really early days right now. Email in profile if you want to give it a try at no cost.

#127Nowhere near as impressive as some of the things here but I’ve been slowly growing out a daily puzzle website https://regularly.co - I built the first few games for my wife, no subscriptions, no pay to play, no sign up needed.
Im launching a new word game next week which I’m super excited about. If you do play it and have any feedback do shoot me message!

#128If you work in machine learning, we are building a much more powerful and faster Neptune/Wandb replacement. https://minfx.ai/
Can it be hosted locally? Would be great to beat mlflow
We are planning to make an offline local version, see also https://minfx.ai/why.html and Web + Native

#130Still working on a system for allowing Open(Python)SCAD to model cuts for a CNC using G-code, and just added support for 3D Printing via Full-control G-code:

Hopefully I can restore the OpenSCAD interface layer and get it working with OpenSCAD Graph Editor:
https://github.com/derkork/openscad-graph-editor
again. Having trouble finding FCG examples which do more than move in straight lines though...
