I hear regularly that people see #Matrix / #Riot as a IRC client similar to IRCCloud but not as a independent messenger and protocol. This also has the effect sometimes, that they leave Matrix again as soon as IRC become less important for them. Bridges are great but sometimes I have the impression that it would help Matrix if they would talk less about the Bridges and more about the strength of Matrix as such. I'm the only one with this impression? #nf

Good to see that nginx 1.17 is slated to include HTTP/3 support. Firefox supports the current Draft (because we have a Draft version, yay) since November, so this is promising, all things considered. Good work by all involved – some of the working group discussion minutes read intense.

If you want to read up on HTTP/3, I'd recommend the short booklet by Daniel Stenberg (the curl developer): upload.wikimedia.org/wikipedia

We have computed the very first chosen-prefix collision for SHA-1. To put it in another way: all attacks that are practical on MD5 are now also practical on SHA-1.

We have reduced the cost of a collision attack from 2^64.7 to 2^61.2, and the cost of a chosen-prefix collision attack from 2^67.1 to 2^63.4.

Demo: The legacy branch of GnuPG (version 1.4) is vulnerable. We have created two PGP keys with different UserIDs and colliding certificates.

The French government switched to Matrix, the German government evaluates free, open and federated messaging solutions, Nextcloud Talk became a great Slack replacement, public authorities in Germany consider a mass exodus from Twitter & Co after EuGH ruling, next stop Mastodon... Seems like we have both, the (political) momentum and the technology to make 2020 a great year for the free & open internet!

Over the last few days we've had constant requests to respond to @moxie@twitter.com's 'The ecosystem is moving' blog post & recent 36c3 talk - we've tried to articulate Matrix's viewpoint over at matrix.org/blog/2020/01/02/on-.

Found this excellent interactive intro to game theory today!

End of an era, I guess.
