Good math problems are hidden inside textbooks and online documents. To keep up with all the sources in the world is hard. For someone who just wants to continuously solve problems, finding and going through all the sources feels like a hassle. I wished for a website that could just dump all the math problems available in the world out there. And if I could filter the problems by topics, that would be beautiful. teachyourselfmath is a side project that was born out of this need. At its core, it is a math PDF extraction engine. The engine has some machine learning going on behind the scenes…

We just released a fully computer-animated multivariable calculus course in six languages: English, Spanish, German, French, Italian, and Portuguese. Free and open to everyone. Half the course is live now; the rest is coming very soon. We're an early-stage edtech startup. Our goal: use AI to build high-quality, computer-animated versions of every STEM course in the world, in every language, and bring them together on a platform like Coursera, but built for the AI age, with deep LLM integration. We want that literally. Every course. Every language. This project simply couldn't exist without…

Hello HN! Over the last few months I've been working on Differential.dev. It's a tool that I built to solve the problem of connecting n domain services, with the simplest possible abstraction - function calls. (Typescript only for now) Internally it uses a service bus that ferries functions calls, but all of this is abstracted away from a developer. You can use it (as I have) in brown-field projects to split a monolithic service to domain-driven services, without splitting the codebase. It's fully open-source under a GPL 3.0 License:…

In past few weeks, I wrote several chapters to learn Scheme, a programming language of the Lisp dialect. The writing is not final as many chapters are missing. I wrote this because I wanted to improve my Scheme knowledge and increase the (low) number of Scheme literature. The writing is inspired by Calculus Made Easy, which I learned about here on HN. This is why I'm sharing it here. But keep in mind that my writing style is not as good as that in the above-mentioned inspiration. Feedback is very much appreciated.
