DevCon3 LiveStream

Notes of memorable talks.

e.g. mentioned URLs & addresses
e.g. youtube start positions (hours/minutes/seconds in the livestream archives) <-- this is the main usefulness.

Almost ALL of the talks in the DevCon livestream (Main Hall only). Yes, 35 hours of binge-watching :-) .

Beware: These notes contain only an idiosyncratic subset of talks. Roughly chronological. There were many more. Find them yourself (and if your favorites are missing, just add'em):

Purposes of this text:

  • other people can already start watching now, even before the talks are edited and published. Thus the youtube URLs with exact HOUR:MINUTES:SECONDS links.
  • myself I will more easily find stuff later.
  • placeholders to perhaps insert more info about each talk
  • keeping the mentioned links somewhere. There is so much happening.

There might be some more info in the chat https://gitter.im/ethereum-unofficial/devcon (please create an official chatroom).

What a pity my body was not in Cancun, but you can be sure - my mind was. Greetings from London.

Good night,
Andreas Krueger

Participatory

Not sure when/if I ever find the time to further edit this. So:

  • You just go ahead, and improve this if you want to; perhaps add your own notes, do a pull request, whatever. https://github.com/drandreaskrueger/devcon3
  • Just one wish: Please do not write their email addresses in cleartext, to hide them from spambots (search for (at) and you'll see). Thanks.

News 2 weeks later: correct times, other people's TOCs

About the wrong times: It must have happened, because they had initially cut off the beginning of Swarm's and Fabian's talk; and when they later re-inserted that, everything got shifted. I have now corrected the wrong times, if you still find some, please tell me. Thanks.

Moreover: There were many more than the 42 talks which I have mentioned here. Ryan Yosua has gone through the pain of linking them all in his blog. Also, most of the yotube videos now have the beginning times as a comment.

News 10 days later: Mosaic and Markdown

My twitterphotos/ Mosaic got a lot of retweets, thank you very much.

I finally took the time to transform this .txt into a .md file. Feel free to further improve it.

News day 5: twitter photos

I have downloaded ~1000 of your beautiful twitterphotos/ - thank you so much; that way we could see a bit more of Cancun too. Love the crocodile pictures.

TODO

  • Most urgent TODO: Markdown formatting. DONE.
  • making this strictly chronological
  • perhaps invent some scheme that all this can still be parsed afterwards?

News day 4: a few times might be wrong now (CORRECTED)

Arrrghh. They seem to now have f**ked with their youtube videos, grrr sabotageurs. Some time positions like &t=3h20m30s were suddenly wrong.

I have corrected them now.
If there are still wrong times, then please you look up the correct times, and please fork this repo and send a pull request. Thanks a lot.

N.b.: not strictly chronological yet. (day 1 is further down)
