learn

I am building https://learnawesome.org It's an attempt to organize world's knowledge. Right now, it looks like GoodReads-like social network for learning resources organized by topics, formats, difficulty levels etc. But there's a knowledge-graph that separates ideas and the medium those ideas are expressed in. For eg: "Sapiens - the book" and "TED Talk given by Yuval Harari" are connected to the same node. This idea isn't anything new. Here is Danny Hillis talking about it at OSCON 2012: https://youtu.be/wKcZ8ozCah0 The code is open-source on github: https://github.com/learn-awesome/learn/

GoodReads is all but dead for many. A few months ago, they deprecated their API keys (without notice). I started building a GoodReads-equivalent but realized that many people care more about learning from multiple media formats (blogs, videos, research papers, interactive explorables, podcasts, courses etc) rather than simply reading books. Because there are too many projects attempting to build a new GoodReads, I ended up building something more oriented for multimedia learners. It’s up and running, open-source, built with Ruby on Rails and supports protocols like ActivityPub, RSS etc. There is a companion browser extension, integration with Slack groups, Twitter and more, and a WIP mobile app. Like GoodReads, you can build your learning lists and embed them on your sites. It participates in fediverse so your reviews can be broadcasted

I have been adding a number of these free books at https://learnawesome.org/ Do you really care about the format being PDF or is it about the books being FREE? I'd like to make common queries like yours easier. LearnAwesome is open-source, so of course you're free to contribute: https://github.com/learn-awesome/learn

Internet has some amazing learning resources these days. Not just articles like these and videos, but also interactive explorables. Even my 7yo was able to understand basic aspects of game theory and complex systems with the help of explorables made by NickyCase, MeltingAsphalt etc. Most recently, I taught myself to not just solve 4x4 Rubik's cube but understand its connections to ideas in abstract algebra such as commutators. I feel extreme gratitude for all the people who create such enlightening material and offer it freely, without asking for a paid subscription to their Udemy course. It inspired me enough that I started creating a DMOZ-style catalog of learning resources as a FOSS project: https://github.com/learn-awesome/learn

> shift this burden to the medium This is beautifully expressed. Knowledge consists of connections across concepts but those connections are rarely shown explicitly in textbooks. Even wikipedia, while allowing you to traverse the connections back and forth easily, does not do a great job of giving you the bird's eye view of a subject or a field. Check out this "map" of mathematics: https://www.youtube.com/watch?v=OmJ-4B-mS-Y Every subject needs a similar map. Besides visualizing the connections, we'd also need interactivity to the topic that helps with forming new mental models - which is the core aspect of learning. Jupyter notebooks, ObservableHQ, Mathigon are some of the good projects working on this aspect. Disclaimer: I am building the open-source project https://github.com/learn-awesome/learn/ which is attempting to build the comple

Yes, it looks like we can learn from each other. Check this from our issue board: https://github.com/learn-awesome/learn/issues/79#issuecommen... Drop me an email at team AT website, please ?

Thanks for pointing it out. Filed an issue for this: https://github.com/learn-awesome/learn/issues/185

Thanks! Created this issue for this fix: https://github.com/learn-awesome/learn/issues/184

Yes, the topic/knowledge taxonomy is an important part of it. There are ideas from ConceptNets to Faceted classification. For now, I have taken a pragmatic call to have maximum two parent topics for every topic node here. This allows me to show the hierarchy here: https://learnawesome.org/topics This taxonomy design is being discussed here: https://github.com/learn-awesome/learn/issues/14 Feel free to suggest better approaches.

Clickable link: https://learnawesome.org Code repositories for: - Web application: https://github.com/learn-awesome/learn (license is AGPL 3.0) - Browser extension: https://github.com/learn-awesome/webextension It cleverly generates a question/answer pair from a simple text selection from your Web reading: https://medium.com/learn-awesome/practice-what-you-learn-usi... - Reusable flashcard practice widget: https://github.com/learn-awesome/flashcard This is built with VueJS and lets anyone create articles with spaced-repetition built-in similar to Andy Matuschak's fantastic posts on Quantum computing. - There's even an absolutely rudimentary mobile app on Android built with Flutter: https://github.com/learn-awesome/mobile-app which just makes it easy to look up links or add them to the repository

I wanted to encourage people to join and start contributing to the repository. Started a discussion on this question here: https://github.com/learn-awesome/learn/issues/79#issuecommen... Feel free to suggest more ideas to make it a vibrant learning community.

I recently built a spaced-repetition module in learnawesome.org to help users practice and remember not just from whatever they're reading, but also by taking notes from meetings, conferences, videos etc. Wrote an article about it: https://medium.com/learn-awesome/practice-what-you-learn-usi... Since learnawesome.org is open-source, if anyone needs a Ruby/Rails implementation of spaced-repetition algorithm, feel free to take code from here: https://github.com/learn-awesome/learn/blob/master/app/model... Feedback and pull requests are of course welcome :)

Another example of ActivityPub is learnawesome.org (which intends to be an equivalent of GoodReads but for all media formats, not just books). I recently implemented ActivityPub support in their webapp, so it's now possible to subscribe to a LearnAwesome user's book/course reviews and get that feed in Mastodon or any other ActivityPub client. The ActivityPub standard is straight forward and was quite fun to implement actually. Here is the issue in case someone is curious how to do it in a Rails app: https://github.com/learn-awesome/learn/issues/121

Thank you. Fixed all of this. We do have an open issue for this: https://github.com/learn-awesome/learn/issues/118 Hopefully, some fellow HNers might find this an interesting project to hack on and make it better. :-)
