JuliaCon 2019 is streaming live on the Julia Channel on Youtube. Every video has its own livestream and will be linked on the channel page as it goes live.

I just want to take a minute to appreciate the quality of the livestreams this year. I am glad you guys got this YouTube thing all figured out

With some help from @cormullion’s gist I put together a spreadsheet where I’m adding links to live streams, slides, repos, other supporting material etc. I’ll update it as I watch the talks or if anyone points me to relevant material. By the time the whole thing is over I think we should have a pretty comprehensive list

The code I used earlier this year (YouTube views and likes) to scrape viewcounts and stats doesn’t work today (Google knows why :)), so the viewcounts are obstinately stuck at 0. Will update once or twice more perhaps, rate-caps permitting.
You can use this link to directly see the current live streams and upcoming streams.
My sheet of livestream links is now more tweetable: https://tiny.cc/jc19talksummary. I’m not on Twitter so someone might want to get that out there if it seems useful. I’ll continue to update it with links to people’s slides, repos, papers etc as I see them.

@swt30 Thanks a lot.
Yesterday, I took advantage that my girlfiend was out, and I pass the majority of the afternoon watching JuliaCon 2019 talks . There are very interesting talks, and you can learn a lot (even about solving cryptic crosswords 
).
I have scraped the Youtube data on all the Juliacon 2019 talks and have created a “score” to help me give a quality indications of all the talks so I can prioritise which to watch. The score is based on some implementation of adjusted likes/views - adjusted dislikes/views.
Base on current data “Mining Imbalanced Big Data with Julia” is the best talk at the Juliacon 2019!
Code is here https://github.com/xiaodaigh/juliacon_youtube

Nice work. The trouble with the likes and dislikes is that it’s YouTube… Most disliked video? “Raising Diversity and Inclusion”…
5 Likes
The problem with that may be that the video is 2 hours long but video only starts one hour in.
Weird: How is “The Unreasonable Effectiveness of Multiple Dispatch” with a huge number of views and the largest number of likes number 8?
Based on the data, the ratio of likes to view is not as high as number 1.
I see now: it is the ratio (ratios) that play a role.
Nice job! Fun to see that people are eager to know what’s bad about Julia.
How about ranking them simply on the basis of views? I find that #views also intuitively also makes sense.

What I was going for was to uncover interesting content that may not have been that popular looking at the title or because presenter is not very well-known.

The formula needs to be more thought out for sure.
Hmm, that seems too simple. You should make a neural net that classifies that topic based on views, likes, and the number of vowels. Then rank on predictive accuracy. This is Julia, come on!
Made a table that actually has links to every video
