Some years ago, I hosted my own matrix server for a few months. I’m an experienced self-hoster, but I remeber that Matrix was paticularly hard to host, requiring weird proxy rules, DNS adjustments, federation never worked reliably and push notifications never worked at all. I ditched the project soon because I also had no real use for it. However, I recently had some ideas where a Matrix server would be useful again. Has anyone attempted to install it recently and can tell me whether the situation has improved? Also, which server do you recommend? There still is synapse but I found it paticularly complicated to host. Dendrite is now archived and the current fork seems to be tuwunel which doesn’t seem to be under very active development.
You’re absolutely incorrect about IRC. Would you like to learn? Open IRC federation is basically never used anymore and the few networks that exist are very stable (if not completely calcified), but it is a core feature of the design, and in the old days, massive interconnected networks of IRC servers like EFnet and Undernet spanned the globe, there were even some servers that allowed open federation (EFnet is actually named for it – eris-free-net referring to the last server “eris” that supported free federation), and at some points Netsplits were a frustratingly daily occurrence. Like with any federation, abuse is the reason we can’t really have nice things anymore, but IRC absolutely supports federation. Not very well from a modern standpoint since it didn’t really keep up with the abuse arms race, but when it was first conceived it was way ahead of its time.
