#452building a GPS tracker for my cats who like to wander outside.
some features:
- no monthly subscriptions
- location via GPS/GNSS
- a screen that hangs on my fridge (akin to marauders map, to see where the cats are at all times)
- the location data stays local always.
The tech will be extended to more products - a watch for adults, kids tracker etc. Will release here once I have all the tests completed!

#453I've been working on a voxel engine in my spare time for 10 years, this year. I wrote everything from scratch, from the memory allocators, font rasterizer and a programing language all the way to collision detection, renderer and gameplay code. It's been a journey! https://github.com/scallyw4g/bonsai https://github.com/scallyw4g/poof
Hey! I've seen bonsai before. Amazing work!

#455Building https://lenzy.ai - helping products built around chat with AI (think Lovable or Cursor) reduce churn and prioritize product improvements by analyzing their user's chats.
I started about 3 months ago, focusing on making my 2 early adopters happy. One of them is ready to start paying soon!

#456I'm working on a native MacOS Postgres client: http://github.com/ravelantunes/Searchlight
I've been slowly chipping at it over the last couple of years as I find time, and I like it enough to already use it as my primary client (although still buggy here and there).

#457Earlier quoted context omitted.
Coming soon! Some people have tweeted about us unprompted: https://x.com/jaybaxter/status/2001729207873999094 https://x.com/FeifanZ/status/2001168758740803781 https://x.com/VivaLaPanda/status/2000758151851966770 https://x.com/__venki__/status/2000378422456148081
What's the reason it is so shockingly expensive?
That's what good lights go for, they're niche and people pay good money for them. I really liked my office lamps and I wanted to get the same for home, after a quick search I discovered they were 1300+ euros

#458I'm building an agent builder and execution platform. It's a multi model, multi agent system with lots of tools (bash, databases, APIs, crawler...).
Agents are codified for specific goals. Any business process that needs agent based assistance is broken into workflows and steps. Each step is assigned to an agent. Integrations (API or file access) is requested. Then user can try out, tweak and finally deeply.
The aim is to build a diy platform work configuration, tracing and evals in one place. Code generation is used internally. User doesn't need to write any code.

#459I've spent the past ~year compiling a US nationwide land parcel dataset. I posted it to kaggle a few days ago: https://www.kaggle.com/datasets/landrecordsus/us-parcel-laye....
I'm around 99% coverage of the US. Learned a lot about land records and GIS along the way.

#460I’m working on a real-time tracker for the Canadian Parliament. While the official data is technically public, it's practically inaccessible (buried in XML feeds and legacy sites). Phase 1 was building a modern ingestion engine and freeing the information to make it more accessible. The goal is to make legislative data as accessible as sports stats. I'm almost ready to launch the MVP; I'm just doing some bugfixes and…
This is a really cool idea! I remember once looking at all of the actual concrete actions taken and being surprised at what was actually done (not very much at the time!). Maybe it is better now.
