Show HN: Search engine for lectures
- mceoin 9y agoOn mobile, The email modal is over most of screen and can't be closed...
- kbhat 9y agoSeconded. It's super annoying and while it can be worked around, I don't like having to deal with it following me around as I scroll.
- garysieling 9y agoReally sorry about that. I pushed a change to hide it when it doesn't fit. That area of the screen is supposed to be an informational card, like you see in Google search results. When I have the data, it shows books a speaker has written, and I'm working on getting more in there.
- kermittd 9y agoInteresting project, but as op said email modal on mobile can't be navigated out of.
- garysieling 9y agoSorry about that, it should be fixed now.
- ychandler 9y agoReally interesting, are you searching through Youtube? Wonder what other sources that you are getting the source data out of
- garysieling 9y agoI'm collecting lists of speakers/conferences and doing very targeted crawling. There are a couple essays on the site (in progress) if you're interested in more detail- https://www.findlectures.com/articles/2017/05/15/Building-a-Crawler-in-Node-JS/ https://www.findlectures.com/articles/2017/05/15/Building-a-...
- pathsjs 9y agoI tried to look for some math topics, such as "harmonic analysis", "lie algebras" and "model theory" - unfortunately none of the matches were relevant for any of the queries
- garysieling 9y agoThanks, I'll look at adding some math classes.
- personlurking 9y agoLooks interesting. As someone going through all of Dr Jordan Peterson's lectures, I put him in the search and only one of his talks (with Joe Rogan) came up. Please add his stuff if you get the chance (he has a YT channel). It'd also be nice to be able to find like-minded talks. Also, when pressing the back button through some searches, the URL changed with me but the results stayed the same.
- garysieling 9y agoThanks for the feedback!
- wodenokoto 9y agoThe idea is really good, but there is still a long way to go. Searching for "python simulation" (a suggested search, btw) yields results such as "introduction to programming lecture 23" - short of watching the lecture, how am I supposed to judge it's relevancy? There is no description, and the title contains neither "python" nor "simulation". Also, the email sign up modal is enough to not make you want to return.
- garysieling 9y agoThanks for the feedback. The email thing should be better now. Agree on the relevancy issue, I'm working on ways to improve that. If you do a search that matches the closed captions, it will tell you where in the video the match starts.
- sks4903440 9y agoGood initiative. Suggestion: The content could be categorized.For example - the lecture of MOOCs should be at one place. Problem: Say, I am browsing page 5 for some query and I change the query, it shows page 5 of the current query rather than page 1 and if the content of current query is not enough to reach page 5, it shows "No results found, sorry!".
- garysieling 9y agoGood feedback, thanks.
- serbrech 9y agoNice! That's going to be very useful when learning a new topic/technology How are the hits ranked? I imagine just time? Do you have a list of all sources you used?
- garysieling 9y agoThere are about 20 factors right now, which I've been tuning over time. They are applied as I'm able to get the data for the talk. Here is a selection- 1. Is the publisher of the talk good? (whitelist) 2. Is the talk referenced in social media (e.g. HN) 3. Safe for work (i.e. you could use in a lunch and learn) 4. Length (15-50 minutes preferred) 5. Is the speaker a keynote level speaker? 6. Are there closed captions? Can the video be embedded? 7. How often does the speaker say 'um' (or similar) 8. Is the talk in English (there are some in Russian and Arabic, but only small collections) 9. Are there notable audio quality issues (channel balance) 10. If it's a historic talk, older talks get higher ranking 11. If it's a technical talk, these get lower ranking, unless you filter to that 12. Is the speaker influential enough to have a wikipedia article? 13. Has the speaker written books? 14. What is the role of the institution that sponsored the talk (conferences are neutral, think tanks, etc lose some ranking)
- prab97 9y agoIt shows ApplicationError. Got a HN hug of death, or are you updating?
- garysieling 9y agoSorry, looks like a memory issue on the Solr server. I shut everything else down, so hopefully it holds!
- ThomPete 9y agoGreat resource but your filtering needs some serious work. I managed to filter myself into a corner with no way to get back.
- garysieling 9y agoThanks for the feedback - I'll look into fixing that.
- msnower 9y agoAs someone who does a lot of learning online, I can see the usefulness of this! It'd be a lot easier for me to use if the filters on the side of the screen if they matched my search queries more closely. Currently, searching for "react.js vs. angular.js" leads to Ronald Reagan and Bill Clinton being options in the "speaker"filter.
- garysieling 9y agoThanks! I think you'll get a better experience if you filter to "Technology" first, if you're using it that way. I'd like that to be more seamless, but haven't found a good way yet.
- mrleinad 9y agoPagination doesn't seem to be working, I need to change the URL to go to page 2 and so on when filtering a cathegory.
- mrleinad 9y agoe.g.: https://www.findlectures.com/?p=1&class1=Technology&category_l2_Technology=-Machine%20Learning https://www.findlectures.com/?p=1&class1=Technology&category...
- garysieling 9y agoSorry about that, I will look into this.
- mrleinad 9y agoThanks! Great site!
- netcan 9y agoGreat project Gary. Thanks for sharing (and building). I would love to see this kind of content get some love.
- garysieling 9y agoThanks! I'm getting a ton of good feedback and lots of speaker recommendations, so the next version should be even better!
- coding123 9y agoJust curious, is this using React/Searchkit/Elasticsearch under the hood?
- garysieling 9y agoIt's a custom React UI + Semantic UI + D3 + Solr. If I had found Searchkit when I started this a year and a half ago, I would have used it!
- sztanko 9y agoGreat project, thank you for your time! (minor bug: Searching for "top 20%" results in "URIError: URI malformed /public/lecture_search.bundle.js?v=1.0.22:79346")
- garysieling 9y agoThanks, I will look a this!
- catshirt 9y agothis is awesome. thanks!! obviously a huge undertaking probably not in your wheelhouse- but finding a way to map all these topics together would be amazing.
- garysieling 9y agoI'm not sure if this is what you mean, but looking at ways to map concepts together with word2vec. E.g. so you could search "writing NOT code" and get literature, or facets more conceptually related to search results.
- catshirt 9y agointeresting but i was thinking more of a Khan-style mindmap: http://2.bp.blogspot.com/-ChwlFfoI4TE/TtEl5UA1AkI/AAAAAAAAAeI/MCR3dwjo8xc/s640/Khan2.png http://2.bp.blogspot.com/-ChwlFfoI4TE/TtEl5UA1AkI/AAAAAAAAAe...
- ProMarc 9y agoI think a language filter would still be good.
- Micoloth 9y agoHey this is pretty cool! I looked for a specific CS topic and the result was definitely better than Google's. I'll probably keep using this!
