From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Why the switch to XMPP btw?
Better native client support for the most part, but xmpp servers also show themselves better (faster, more stable...) than matrix.org I think more matrix users should consider using smaller instances tbh
Thanks for sharing, I’ll check out XMPP too - last time I checked was 10 years ago :D probably a lot has changed
Matrix on smaller instances suck because of how bad the protocol is. It "re-plays" the entire history of the channel on first join because channels need to be consistent between all instances because Matrix isn't just a mediocre chat protocol but a generic data protocol that's been beaten into the shape of a mediocre chat protocol.
It tries contacting every instance in a channel for their keys. Even the dead ones. And yes it takes exactly as long as you think it does for them to time out. Dendrite solves this by asking matrix.org for everyone else's keys by default.
But because channels are completely synchronized at least you get to easily migrate channels between instances just by assigning an alias and telling people use the alias to join instead.
Woah, didn't know that! I remember searching for older messages in Matrix be really bad. I only use IM software for 1to1 conversations, so I probably don't know the worst of the protocol.
Sounds a bit too centralized for me
You can turn it off however that makes join times to any channel with history (say... the dendrite release announcements channel for example) unbearably slow to join.
I look forward to the day that Synapse is deprecated in favor of Dendrite or Conduit.
