Then I found an HN comment I wrote a few years ago that confirmed this:
“[...] I remember that day pretty clearly because in the same lightning talk session, Solomon Hykes introduced the Python community to docker, while still working on dotCloud. This is what I think might have been the earliest public and recorded tech talk on the subject:”
YouTube link: https://youtu.be/1vui-LupKJI?t=1579
Note: starts at t=1579, which is 26:19.
Just being pedantic though. That’s about 13 years ago. The lightning talk is fun as a bit of computing history.
(Edit: as I was digging through the paper, they do cite this YouTube presentation, or a copy of it anyway, in the footnotes. And they refer to a 2013 release. Perhaps there was a multi-year delay between the paper being submitted to ACM with this title and it being published. Again, just being pedantic!)
