Products that do what Class Central - Summary of Stanford's free online courses does
Built most of it over the Thanksgiving weekend and here is the result: www.class-central.com Built in PHP/MySql using Symfony2, Doctrine and Twitter Bootstrap. Source code can be found here: https://github.com/dhawalhshah/class-central The 'extras' folder in the repository contains a dump of the database dump(with all the data you see on the site) and the schema. I have also created a circle of all the instructors with Google+ accounts: https://plus.google.com/107809899089663019971/posts/AoJMVCeQw62 Any feedback/suggestions would be appreciated.

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].

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…

First, I'm by no mean a programmer. Second, I am reading HN for years, just registered to make this public and see if it can be useful for someone. I have nothing to gain monetary. A while ago, I decided that no blogging system was simple enough and I looked for a small wiki to use as a CMS/blog. Found WikWiki on C2.com and I mixed it with some basic Markdown syntax, a minimal template and added password protection. The result is a single php file, no database and no dependencies. Code is a mess, not modulable, probably wrong in so many ways, but it can probably used by some as personal…

Hey HN, I posted GitClassic here 2 months ago- since then I've rebuilt most of it based on what people asked for. https://gitclassic.com What's new: Issues, PRs w/ full diffs, repo intelligence (health scores, dependency graphs), trending/explore, bookmarks, comparison tool, and advanced search. Every page is server-rendered HTML- No React, no SPA, no client bundle, pages under 14KB(gzipped). Try loading facebook/react and compare it to GitHub load times. Public repos work without an account, Pro adds private repo access via GitHub OAuth. Stack: Hono on Lambda,…

I've been working for about 8 months on http://www.Learneroo.com, a site to teach programming and more through challenges. I created the site and all the content on it, and I'm looking for some feedback. Thanks!

Please give me some feedback on my weekend/evening project http://ycpages.info YCPages is a CrunchBase sort of service just for YC funded companies. Company/founder details are pulled from CrunchBase using their API. I have checked founders info by looking their LinkedIn pages/Twitter etc. So i am confident 95% information available on YCPages are accurate. Next Steps, == Adding the Tech Stack info == Rankings from Alexa, Compete, Quantcast, etc If I can get the founders answer few of my question about their experience I will add them as well. Any feedback would be highly appreciated.…

After I posted about https://cosme.dev/ask-docs on Reddit I received some messages asking me how If I was going to make the code open source or if I could show them how I did it. So I decided to create this repo so you can take a look at the code and maybe apply the same techniques on your own apps. It's made using only PHP as language so I think is pretty different since most stuff out there is made using python or javascript. It uses the OpenAI API and Redis as a vector database.

http://www.imakesnowflakes.com/cliche-introduction.html This is something I made to automate a bunch of tasks for the modern php developer. Cliche works with a projects auto loader and can 1. Accept a set of partial class name as command line arguments. Using an interactive session with the user, Cliche resolves the partial class names to their proper names. It will generate the class file with all the required import statements (taking care of any conflicting imports) and any methods declared by the interfaces are generated as empty methods. Lastly it can place the class file…

I've been working on this for a few days now. The goal is to create a library of the best free educational content available and to build personalised learning paths for each user, using only free resources and at no cost to the user. Let me know what you think.

I made an image sharing application to compete with Imgur. Chances are it's not going to take over Imgur any time soon, so I figured I'd open source it. Stack: * Symfony w/ PHP 5.5 * Postgres 9.2 * Redis 2.8 * Ruby 2.0 (Capistrano) * Vagrant It's a fairly basic Symfony application but also makes use of a lot of Symfony components. It's sufficiently complex enough that you can probably learn a decent amount from it if you want to start playing around with Symfony. It has a few tests, uses Resque, uses the Symfony service container, and integrates with Amazon S3. Check it out, would love…

Hello HN! My name is Rémy and I recently published an astronomy dashboard where everything is open source: the code of the website, the framework it is based on and the library that computes astronomical data. For the last few years, I have been developing the Ruby library Astronoby (https://github.com/rhannequin/astronoby) with as much dedication and perseverance I could while I don't have any scientific academic background. My end goal was to use this library and build a website that not only provides as much data as possible, but let anyone access and understand how it…

Hi, I'm Marcus. I've spent the last 15 months or so home-coding on a document database, after work, on weekends (every waking hour). My plans for this particular weekend was to implement log-structured writing. It went faster than I thought and the results were faster querying times and fast, append-only writes. I've been working on this for almost a decade and being this close to the finish line feels surreal. This is my seventh iteration I believe. Everytime I realized I had an architecture built on a bad model I walked away, often in fury, depressed over my weak coding abilities but…

I wanted to brush up my SQL skills and was looking for an online course that included a live DB. Most PostgreSQL courses require you to create an account or pay. This is probably because they have to bear the costs of running a full server-side database. So I created learnpg.xyz, a collection of PostgreSQL SQL exercises that run client side. Sharing here because it might be of use to people!
