I'm working on a trip planner for vegans. This is designed to solve my particular problem as a full time (vegan) nomad who likes to stay in walkable cities.

I noticed that sometimes, I book accommodations in a new city without realizing I'm very far from the nearest vegan restaurant, having to walk for a really long time to get food, and sometimes getting there after the kitchen is already closed.

The planner helps me find hotels/airbnbs that are within 15 minute walk of at least 3 different vegan restaurants - makes my life so much easier!

A reimagination of SuperCollider architecture.

* No need to invent a new language, use Python! * Use JIT to compile a SynthDef to a proces function! * Eliminate block_size at runtime by compiling a version of each primitive for every 2^n block size. * Watch the compiler do unrolling, vectorisation and merging loops.

Besides, its fun! https://github.com/mlang/mc1 (Nothing to see yet)

One of my hobbies is trying to predict foreign exchange prices (usually EURUSD tbh, but others as well).

I enjoy finding out the actual best-case performance of various technical analysis indicators, and popular "systems", by optimising the indicator's parameters to find the best long term performance. I also design my own indicators and systems in the same way.

To this end I have a C++ ImGUI desktop app with charting capabilities, and optimisation using differential evolution. The app has its operation driven by a c++ class that controls all aspects of its running, by means of various callbacks.

This enables me to test lots of strategies quickly, exploring the parameter space with the optimisation functions.

I've considered open sourcing the app, though I'm not sure there would be any interest. The codebase would need cleaning up first anyway! :-)

I've been working on a kind of strategy game called Fall of an Empire ( https://fallofanempiregame.com ), it's a bit like a mix between Crusader Kings, Total War, Mount and Blade type games (just the overworld, not the battles), but rather than expanding you're trying to prevent an empire from collapsing. It's a ton of work, especially with the number of systems - you've got combat, resource management, settlement de…

So, you thought that Attila wasn’t dark enough?

In all seriousness, there’s a constant nagging in TW community for more historical games. Pharaoh didn’t cut it for the wast majority of players. You could capitalize on that, the genre would benefit from that.

I've created a two player wordle style game. https://twordle.app

The backend is a web socket server written in go and the frontend is solidjs. Two technologies I've been wanting to use properly in a project for a while. Would recommend this to anyone wanting to improve their understanding of go's concurrency model. I've really enjoyed working on it, if anyone can think of any improvements please let me know!

I’m interested in High-Frequency Trading (HFT) using algorithms, starting with basic trading algorithms like RSI Divergence and Arbitrage. I’m utilizing the Binance API to retrieve ticker data. If anyone has experience with this or is interested, I’d love to connect and discuss.

Preparing my PyCon IL workshop, a competitive platform where you write code to solve simple games (think snake, pong etc.). Here are some screenshots: https://imgur.com/a/VDKfmjO

After it's done I hope to add a demo to my blog.

Cheers for all the interesting work going on here!

I've been working on something to handle the "plumbing for your observability". It's a way to collect, stream, and route observability data that can get it from and into a wide variety of systems.

It's not targeted at the 'cloud native' crowd, but rather more at traditional on-prem infra.

It is all manageable via an API and provides a Kafka API for streaming data (RedPanda under the hood).

I believe typescript / js is missing standard library and find it rewarding to work during weekends on those lower level libraries/modules with no/low dependency fanout, publishing them here [0] when they're ready to see the light.

They're driven by what problems I see at work and while playing with other weekend projects so coverage may be asymmetric (some parts are well covered, others that should be are absent >).

I find definition of success as just "working on it" very pleasant.

I'm scratching an itch. I'm a huge fan of system monitoring and alerting when they go down. It allows the engineers in charge of the production systems to sleep well knowing that things are working. There's a gap for email monitoring. How many times did you have to awkwardly explain why the notification emails in your app stopped sending a month ago? Or that time when the weekly summary report did no go out on Friday…

This would have saved me a few times back when on-prem exchange was a thing.

First indication tended to be a call from the ISP saying they lost contact with their equipment.
