I've been a longtime member @ HN, but I haven't been a developer. In fact, my only HN submission has been one asking how to learn to code (http://news.ycombinator.com/item?id=820741). My cofounder and I decided to solve the problem by making a simple, interactive way to get started with Codecademy. We'd love your feedback. If you're interested in helping us to get more courses up (on any topic!), please send us an email at [email protected].
- IWI wished for a site with a growing list of math problems, I built it2024 · teachyourselfmath.app · ▲384
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…

- MFMoocable – find people studying the same online course/book2024 · moocable.com · ▲161
Hey, everyone I made a website that lets you find study partners/groups based on the specific course/book you are studying. It's 100% free + no registration required. Why: I know there are many subreddits for finding study partners. But, one of the biggest reasons we can't find the right partner/group is lack of clarity. Most posts that I read on Reddit were something like: "I'm interested in programming. Let's study Python together..." - That's not a clear goal. But, when you say "Let's study the Python for Everybody course on Coursera. I'm from Mumbai, India, and I'm looking…

Got rejected from YC a few times, so I built a site to collect lessons, reflections, and what people would do differently next time. Thought it could be helpful since most founders apply more than once anyway :) Hope it's helpful: https://ycrejection.com/

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
