I have been working on and off on https://www.whichtemple.in - it is a collection of ~ 2700 temples across India, with images sourced from wikipedia - it shows you a random temple each time you visit - it has a map view of temples across India So this is just the tip of the iceberg. I am trying to build a catalogue of all temples, starting with India, and expanding on to the rest of the world. The focus is on temples…

A fun game would be to quickly guess the religion of a temple? Could familiarize people with the common iconography of the various dharmic religions.

Two open-source initiatives:

1. https://preseason.ai Basically a benchmarking platform that measures how the top LLMs recommend devtools when prompted to build different types of web apps.

2. https://widen.dev A native Mac desktop Postgres GUI with text-to-SQL. You can even use the LLM that already comes installed in your MacOS.

Would love to filter this by states so that I can go to the interesting temples in my state first before trying out other places. Would make it more functional.

An agent harness that is kind of like airflow for agent tasks.

I thought open claw was cool but could never use something so insecure.

Each run is in a container. One network bridge out so everything from tool calls to model communication goes over the bridge.

Each run has a capability token and the host checks grants for the tools attempting to be called.

Core super thin and everything from credentials handling to model communication is a package.

Finally got it alpha and have some useful jobs set up like it triggering jobs on an alert channel in slack. Debugging it with tools like GitHub kube and our work mcp and the dropping a comment on every alert with the cause.

https://ottoharness.com

Still closed source but hoping to change that after some more testing.

https://dipstickalerts.com - I've been working on this during my kid's naps.

The web app allows car owners in the U.S. to see a list of all the service bulletins the manufacturer has sent out about your car over the years (called Technical Service Bulletins or TSBs). You can subscribe for new bulletins to be sent to your email as well.

These service bulletins are not only recalls but also fixes for known issues with the car.

I found reading these bulletins super helpful for my own car. There were some symptoms I would have never noticed without reading through these bulletins. For example: the tailgate did not lift up all the way in cold weather. Turns out this was fixed and covered under the extended warranty.

The infrastructure is all built on top of Cloudflare workers. I use Gemini Flash Lite to summarize and filter the bulletins.

This is my first web app (thank you AI) so any feedback is welcome!

I had issues with reproducing some fuzz testing failures in CI locally; turns out that glibc, musl and macOS actually DO NOT return the same floating point values for certain trig/transcendental functions across all OS'es, so I decided to rectify that by spelunking a deep rabbit hole: https://github.com/pmarreck/random

In order to make it work, I had to re-implement some math, so I avoided floating-point altogether (IEEE754 is a personal pet peeve) and went with mantissa and exponent fixed-point decimal. Or should I say binary, because the "decimal place" is the number of bits, not the number of base-10 decimal places.

Apparently this is the only deterministic, cross-platform, cryptographically-secure procedural RNG that has many types of distributions (uniform (default), normal (Box-Muller), exponential, Poisson, log-normal, beta... all with configurable inputs AND which will plot the distribution for you in the terminal!) AND is guaranteed to give you the same values... Everywhere. (Because how the fuck has this not existed yet??) Implemented in both LuaJIT and Zig with C FFI. So there you go. MIT license. Enjoy your deterministic but still very random numbers, on every OS, identically.

(It sources the best-in-class recommended source per OS if you want true random. It will do that too.)

A boat game for 5+ age group! I was never much of a game developer, but recently my 5 year old son wanted to play a game so we decided to build one together. It's a boat game, you basically steer a boat in an isometric 2d world, transporting passengers, cargo etc between ports. As we designed it, the ideas just kept on coming. He made or directed a lot of the art inside of the game (even the audio), and we included f…

This looks really nice. Given the target age I imagine there's not a heap of text, so you could probably get away with LLM translations. Be sure to share it again in the coming months if you add English :)

Im working on what i call a spreadsheet data platform. It looks like a spreadsheet but all the components are plugins which means the user can provide (even write their own).

- Dont like the limited functions available in formulas, write your own. Yes i know this isnt new, just highlighting a starting example.

- Dont like how values are formatted in calls, write your own.

- Dont like templates, write your own script that generates the "empty" or not so empty spreadsheet.

- Dont like clicking on icons, write your own scripts or plugins that execute in context, which makes snippets to do basic things become very brief, because theres no need to load and save the file with the spreadsheet or even select the range with a query.

- Want a terminal, i have one. Everything in a spreadsheet is a file, just like *nix. Read/write a cell, is as simple as reading /cell/A1.txt or /spreadsheet/123/cell/A1, because the environment has smarts like environment values (eg SPREADSHEET_ID) that are used.

I have many other ideas which are nearly there.
