The use case for this is a bit niche, and better tools exist for this general problem in ORMs and so forth, but it works for a problem I have.

#372Create REST APIs for PostgreSQL databases in minutes.
- one man project (me) - been doing it well over a year now - no sponsorship, no investors, no backers, no nothing just my passion - I haven't even advertised much, this may first ir second time I'm sharing a link - On a weekdays im building a serious stuff with it - On weekends preparing a new major version with lessons learned from doing a real project with it
Not going to stop. But I migh be seeking sponsors in future, not sure how that will turn out. If not that's ok, I'm cool to be only user.

#373I'm playing around with sandboxing techniques on Mac so I can isolate AI tools and prevent them from interacting with files they shouldn't have access to -- like all my dotfiles, AWS credentials, and such. I've created two open-source solutions, one which uses a VM ( https://github.com/webcoyote/clodpod ) and another which creates a limited-user account with access to a shared directory ( https://github.com/webcoyote…
Have you considered using docker? Seems possibly more lightweight than a VM with more isolation than a user account based method.

#374Microlandia, the brutally honest city builder. Posting this for a second time, because i’ve been working super hard on a steam release. last month’s “what are you working on” thread impulsed me to upload this game to itch and 1 month later, i’ve got a small community, lots of feedback and iterations. It brought a whole new life to a project that was on the verge of abandoning. So, I’m really grateful for this thread.…

Quite interesting details.
I wonder if you simulate at individual level or group? Would be cool at individual level each one making decisions individually and see some emerging behavior.
Also how corruption emerges in gov etc
Also if no job maybe they could try uber/food delivery crappy jobs like that or start their own business.
Maybe also less money less likely to have kids? Would be nice to show how poverty helps or not population growth. If too poor might have no education and would make kids, if average citizen and can’t save money will avoid kids. That’s why at individual level simulation could find these emerging patterns. But probably too expensive computationally ?

#375I'm working on a web app that creates easy-to-understand stories and explainers for the sake of language learning. You can listen in your favourite podcast app, or directly on the website with illustrations.
I'm eager to add more languages if anyone is fluent/able to help me evaluate the text-to-speech.

#376Recently I started executing the upstream spec tests against it, as a means to increase spec conformance. It's non-streaming, which is a non-starter for many use cases, but I'm hoping to provide a streaming API later down the road. Also, the errors interface are still very much WIP.
All that said, it's getting close to a fully-conformant one and it's been a really fun project.
P.S. I'm new to the language so any feedback is more than welcome.

#378I am working on the little book of algorithms: https://github.com/little-book-of/algorithms A project to implement 1000 algorithms. I have finished around 400 so far and I am now focusing on adding test cases, writing implementations in Python and C, and creating formal proofs in Lean. It has been a fun way to dive deeper into how algorithms work and to see the differences between practical coding and formal reasonin…
I feel like the presentation of Lomuto's algorithm on p.110 would be improved by moving the i++ after the swap and making the corresponding adjustments to the accesses to i outside the loop. Also mentioning that it's Lomuto's algorithm.
These comments are probably too broad in scope to be useful this late in the project, so consider them a note to myself. C as the language for presenting the algorithms has the advantage of wide availability, not sweeping performance-relevant issues like GC under the rug, and stability, but it ends up making the implementations overly monomorphic. And some data visualizations as in Sedgewick's book would also be helpful.

#380Headbang, a rhythm game that you play by bobbing your head while wearing Airpods while listening to music, is what I'm considering building next. The idea came from someone else using Airpods to create a racing game (RidePods). (But also just launched https://ChessHoldEm.net this weekend)
