@raducoravu 🙇 Thanks!

@lief-erickson has a script that should generate the maps and topic. 🙏

Implemented by @lief-erickson in #550 with additional corrections in eb5d084 & 914ce66.

And here they are:

The timeline seems to be backwards, starting with the last presentations and going to the first ones, also without the author names mentioned.

[lief-erickson]

The timeline is irrelevant in my opinion, but we should get author names added. They're in the source. Will investigate.

The 2022 version seems to include a few of the author names, but not all.

It would be easy enough to add those and/or manually re-order the sessions to match the agenda, but not sure if the script was originally intended to sort or add authors.
