  AI driven but curated SAT-Math Tutor2023 · sat.amy.app · ▲8

  Hi HN, Last month, I have worked with my team here at Amy.app to make a stand-alone SAT Tutor. I'm pretty excited about this product, as it's our first attempt to make a stand-alone product targeted directly at students. So far all our products were targeted at teachers/schools/publishers. But we never found product-market fit ¯\_(ツ)_/¯ Our SAT-Math tutor is designed to find your knowledge gaps and gets you up-to-speed as fast as possible. We believe it offers a fresh approach on how online learning usually works. Please let me know what you think. The product has a 3 days…

  Term.everything – Run any GUI app in the terminal▲1,094

  I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

  I recreated Windows XP as my portfolio▲1,032

  Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
