A multi-community feature like multi-reddit wouldn't be that hard to implement. Basically build a subscribe list that isn't owned by a specific user and come up with a way to link them by name and ID. Being able to share community subscribe and block lists would seem a useful evolution of Lemmy.
So if a home server goes down will those posts disappear from the community server?
terminology wise, "home server of a community" and then there are remote-servers for that community. And Lemmy community/devs tend to call a "server" an "instance". To answer your question... if a user is on a remote instance from a community, they are reading copies of the content in a local database. If the community home instance goes down, the copies will still be there in the remote servers. However, they are now in an isolated island and none of the other servers will get the new post and comments - as the home instance of a community does distribution. There isn't any kind of warning indicator that you are on an isolated island.
Nothing disappears, but it is possible to have incomplete replication - have only some of the comments and posts and get an impression that nobody replied or that there isn't much content.
lemmy.ca staff was so frustrated with performance problems a couple weekends ago they cloned a copy of their database Running AUTO_EXPLAIN revealed site_aggregates logic in Lemmy was doing comment = comment + 1 counting against 1500 rows, for every known Lemmy instance in the database, instead of just writing 1 row.
It's wild what lemmy.world has done. If your referrer is lemmy.world itself, a click off their web page, it loads the comment. But if you come from another lemmy instance or just put the link directly into your browser address bar, they reject it with ERR_INVALID_RESPONSE - I can't recall having seen a website do this to try and prevent attacks.
I use that periodically to compare feeds, and like I said sometimes a post or comment is missing, actually I often see a comment that looks like it’s responding to a another comment, but I cannot see the parent comment.
There have been bugs in Lemmy not sending comment deletes to all the instances. And lemmy.world and lemmy.ml were not communicating fro Saturday through Tuesday. Lemmy.world had some significant outages. It gets pretty tricky to track down and identify exact causes while things are unstable.
the module can cause intermittent stuttering, depending on which Ryzen processor you're using. It appeared when the fTPM was in use, it would access its flash storage via a serial interface, and when doing so, held up activity by the rest of the system.
Related to this. I also think lemmy-ui should establish a URL convention for sorting. When you are viewing posts, the sort parameter is on the URL and you can link to a specific sort. But not for reading of comments on a post.
Nolan pushed the limit of IMAX projectors with Interstellar run time in 2014, he went out of his way to find out what the maximum that could be done with platter modifications, an extra 20 minutes.
I miss the days when the internet was populated largely by nerds aiming to make a better world
The BBS and early Internet days were dominated by people who read non-fiction books. RTFM was a common saying in those days.
does anyone else feel enslaved?
“Everything in our background has prepared us to know and resist a prison when the gates begin to close around us . . . But what if there are no cries of anguish to be heard? Who is prepared to take arms against a sea of amusements? To whom do we complain, and when, and in what tone of voice, when serious discourse dissolves into giggles? What is the antidote to a culture’s being drained by laughter?”
