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…

Hi everyone! I’m the founder of Explanations (https://explanations.app). I’m building a website where students can get college level math & physics help for 1/10th the cost of private tutoring. You’d type a question, and your teacher replies by drawing a Youtube/KhanAcademy-style video; and this happens asynchronously throughout the week. When I was studying at MIT, I often had to wait 40-60 minutes in line just to get 5 minutes of “help” from a TA - when I needed 1-2 hours. I understood that TAs can’t spend all their time helping me. That’s understandable. But what made…

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…

My niche is LSAT prep. I write books of explanations to LSAT practice tests. It's a pretty big industry, as people will pay a lot to improve their odds of law school admissions. I realized that, with my books, I have ~400,000 words of quality content that people search for. Lots of long tail searches for individual LSAT questions. So I made a site of free explanations for the most recent LSAT: http://lsathacks.com/ Took about a week to write them and put them up. If it goes well, I'll release my other explanations. Hope to make this a hub for LSAT study. If it's well received,…

Hi, I wrote a distributed SAT solver in Elixir to get a feel of the language, perhaps someone out there might find this interesting. I really don't know if this can be a economic approach to SAT solving. https://github.com/roehst/elisat

I've gotten to the point in my career where I now make strategic decisions often (hiring, firing, choosing what equipment to go with, etc.), as well as in my personal life where I need to strongly weigh my options for a big purchase or investment. I found a not-so-surprising parallel between the two as these decisions "resolved." Am I making good decisions or am I getting lucky? Did some research, read some books, and realized I should get in the habit of tracking my decision process. That quickly turned into the idea that formed Convexly. The landing page is a 10-question calibration quiz…
