Show HN: Learnawesome.org – Open-source learning map for humanity

216 points by mathnmusic 6y ago

Hello HN, Over the last 12 months, I have been building https://learnawesome.org https://learnawesome.org This idea came from Danny Hillis' 2012 talk at OSCON, which itself was inspired from Neal Stepehenson's _The Diamond Age : A Young Lady's Illustrated Primer_ The dream is to build a tool that matches the right learning material to the right student at the right time. Wikipedia is great, but it doesn't do a good job of leveraging the rich variety of learning resources that exist on the Web. Same applies to GoodReads - which is focused only on books, whereas these days we actually learn from videos, articles, MOOCs, tweetstorms, slack/discord groups, podcasts, livestreams, newsletters, online conferences, apps & games, interactive explorables and much more. For now, I am building it as a social network for lifelong learners. It's open-source, built with Rails + PostgreSQL, and complies with standards like Dublin Core's LRMI extension of schema.org and ActivityPub for integration with Fediverse. A GraphQL API is also available if others want to build alternative clients. I have made decent progress so far: Imported thousands of courses and book summaries, built a browser extension for quick lookup/addition to the repository, a spaced-repetition based flashcard practice module. Users can even discover learning resources by recommendations ELSEWHERE (for eg: "Show me books on History which are highly recommended by venture capitalists") I originally started building this as something to help with my daughters' and my own learning. But it made sense to build this as a public good. It would be great if you can give it a try, and share ideas on what would make it better.

  One of the features HN users might like: On a book's page, you will also find links to summaries others have written, or author's podcasts/TED Talks etc - all in one place. Example: https://learnawesome.org/items/5c731d15-6a53-432e-82e4-a4de9fecb2d1-the-first-20-hours https://learnawesome.org/items/5c731d15-6a53-432e-82e4-a4de9... For this to work, I imported links to summaries from sources like sivers.org, blas.com, fourminutebooks.com, sipreads.com etc. Will need help from users in making this dataset even better.

If knowledge has dependencies on other knowledge, you could represent that (a la package managers). If something's general enough, you could have multiple virtual packages teaching it.
- mathnmusic 6y ago
  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 https://learnawesome.org/topics This taxonomy design is being discussed here: https://github.com/learn-awesome/learn/issues/14 https://github.com/learn-awesome/learn/issues/14 Feel free to suggest better approaches.

    Probably not directly applicable to your project but do you know about a project with much more granular skill dependencies? An example are this three skills: "juggling 3 balls" depends on "juggling 2 balls" depends on "throw 1 ball to your other hand without that hand moving much". I'm thinking of a big skill tree like Path of Exile: https://media.esportsedition.com/wp-content/uploads/2017/04/Path-of-Exile-Skill-Tree.jpg https://media.esportsedition.com/wp-content/uploads/2017/04/...

      I'm also really interested in this. Khan Academy used to have a wonderful one, for pretty much all of math up to about undergrad level, but it's gone, for no reason I could find [0]. This seems to be the code that was used to lay it out [1].

  Thank You for pointing it out and thank you OP for building the tool. I have been playing around with it for last 10 mins and I love it. Looking forward to using it.

I used a suggested filter, but changed the topic to something else ("Tribology", randomly picked). There were no results, and I removed filter after filter, but still nothing until I had removed all other filters. In the end, there was just one Tweet. It would be nice if removing filters was easier and quicker, perhaps even a button to remove all filters but topic.

UI bug: when you expand a card under topics, if you click a link that was previously hidden, it doesn't take you to what you click, it activates the click event to collapse the card. (example: Programming languages, "and 27 more", click Ruby)

why do i need to login to simply see the syllabus? I'm not opposed to eventually signing up, but forcing me to before i'm sold on the platform seems premature.
- mathnmusic 6y ago
  Fixed this as multiple users pointed it out. :)
choward 6y ago
> To see this syllabus, please log-in and revisit this page. Uhhh... no.
- mathnmusic 6y ago
  Yeah, this feedback has come a couple of times. Fixed this now. :-)

Submitted contents are not editable and there is no way to change the title of the submitted content. And there is also no way to delete what you have submitted. From a UX point of view I think this is very none-intuitive. (UI-wise it is not bad in general except when you want to select the topic it shows up a dropdown list of 2000 things. Also having fake comments auto-generated makes me feel like this is not a finished product but a POC.) And not sure how but I ran into Error 500 quite a few times. Overall I think the idea is great conceptually but as a product it is trying to do too many things at once. If OP intends to scale it up I think it would be nice to focus on fullfiling a particular niche first. Or in Paul Buchheit's words: it's better to make a few people really happy than to make a lot of people semi-happy i.e. at least from a product standpoint. Of course as a hobby project I think this is still pretty cool! Haven't read the source so can't comment too much on the arch and code. I think it has the potential to be further developed into a very powerful CMS for domain-specific knowledge management, or a CRM, etc. B2C-wise as a content-discovery plaftorm I don't see how this is going to work, except becoming a haven for ads which is probably the last thing OP wants. Suppose it does become a social network as OP has intended, when it grows to a certain scale it will run into the same content moderation problem as hn, etc (https://news.ycombinator.com/item?id=23806426 https://news.ycombinator.com/item?id=23806426). On the other hand B2B-wise it may be able to become ramen profitable. p.s. to OP: can you delete the duplicated entry for me? Thanks. Due to the crashes and the name not showing up properly I submitted my app https://archy.sh/ https://archy.sh/ with mutiple entries.
- mathnmusic 6y ago
  Edit/Delete rights are given when user's profile score reaches a certain threshold. Spam will have to be contained. One approach is to show users only those items which have been recommended by users they follow. Building this as a CMS/CRM is a very interesting idea.

so, i changed the default theme on settings, and now i keep getting an Error 500
- mathnmusic 6y ago
  Oh, I had just removed the old Bootstrap-based code, but forgot to remove this option. :facepalm: I have reverted the theme for you.

Great to see more efforts to map out knowledge for humanity :) Life-long learner myself as well, and I built this tool for maintaining and connecting the dots from disparate learning resources online: https://getrumin.com/ https://getrumin.com/
marvindanig 6y ago
Learnawesome has become my goto resource to find useful links. Thanks for building this! How do you plan to scale this collection while also ensuring quality and up-to-date content/minus the link-rot?
- mathnmusic 6y ago
  The plan is to leverage the social graph for this. Users can follow each other, and they'd see items which are highly recommended within their network.
anistark 6y ago
Great job with knowledge graphs. Specially love the programs part. Any plans on adding more programs to it? Can we build our own programs?
- mathnmusic 6y ago
  Yes, this is where the user community will play a big role.
jbotz 6y ago
Looks pretty good, but when you call it a map it makes me think that it would make the connections between topics, i.e. show the sequence you need to follow to learn things, what are the pre-requisistes for each topic, etc. I don't see that on learnawesome... or am I missing something?
- mathnmusic 6y ago
  See the discussion on this related issue: https://github.com/learn-awesome/learn/issues/14 https://github.com/learn-awesome/learn/issues/14
akinhwan 6y ago
I'm curious as to how you're developing the matching algorithm or recommendation system between learning material and students? I'm trying to do the same but for socially isolated seniors and programs/resources/interventions. Seems that all the examples online are of cases like Amazon, Netflix, or Pandora.
