A small OpenGL tutorial for Rust. Focus on understanding the OpenGL-API and interfacing with it directly, with a few as possible helper libraries.
Some of the chapters I'm currently working on can be found in the preview (https://preview.opengl.zgtm.eu/, ipv6 only).

#564For my work I've developed a web-based Monte Carlo simulator with a visual, node-based editor for building supply chain models. Last week, I started making it available for everyone.
You can have a look at https://simcarlo.com. The tool allows you to see the full spectrum of potential outcomes instead of just a single guess.

#565I am right now building a proactive coach on top of my AI work capture app. Concept is very simple: It takes a screenshot every few minutes and analyzes what you're working on. From there it identifies task blocks, and checks if it should start a chat based on your intentions (eg to tell you to move out of your rabbit hole, take a break, help with a task, ...)
https://donethat.ai Passively processing screenshots is obviously pretty sensitive, it has an option to bring your own (local or remote) LLM, otherwise I process with gemini and never store any data.
It's in beta right now so if you want to try it you have to enable "proactive chat" in settings.
I also made a list of similar tools out there: https://donethat.ai/compare

#568I'm working on Chatolia, an AI chatbot builder.
The goal is to let anyone create task‑specific agents, train with their own data and an embed it into any site.
Training is simple: paste text, upload files (PDF, DOCX, Markdown, CSV), or paste URLs and it will crawl/index them into a per‑agent knowledge base.
I'd love to know what you think.

Rates your sleep, tracks sleep debt, and tracks how workout timing, coffee time, AC temperature, etc influence your sleep.
2.0 is in review - adds support for recovery (based on sleep HRV, HR), and strain.

#570I recently launched a daily word puzzle! https://tiledwords.com It’s inspired by tile placement board games like Patchwork and crosswords. You rotate and move tiles to rebuild a broken crossword. It’s free, web based, and responsive. I currently have several hundred daily players and growing. My wife and I create the puzzles and I’m continuing to fix bugs and add new features. I just launched a ”community puzzle” fea…
This is a lovely game!
This game was Show HNed two times in ten days, [1][2], but unfortunately, it didn't get as much attention as it should! Ironically, this current thread has already gained almost double the comments from both submissions combined!
I whish you best of luck to succeed in your journey.
