In theory, yes. You only need a Activitypub library and some lines of code.

This is not "gmails" behavior. This is called "verb" and it is one of the best things ever. I only use verb for signing up at stuff. So, i can sort, and know when someone misuses my mail address.

And, if i would need to create an alt, to post stuff, that i don't want somebody do bring in connection with me (TIFU, NSFW, whatever you like) i would use verb.

Lemmy Benchmarking - Working on tooling (lemmy.ml)

Heyho,

as a PostgreSQL guy, i'm currently working an tooling environment to simulate load on a lemmy instance and measure the database usage.

The tooling is written in Go (just because it is easy to write parallel load generators with it) and i'm using tools like PoWA to have a deep look at what happens on the database.

Currently, i have some troubles with lemmy itself, that make it hard to realy stress the database. For example the worker pool is far to small to bring the database near any real performance bootlenecks. Also, Ratelimiting per IP is an issue.

I though about ignoring the reverse proxy in front of the lemmy API and just spoof Forwarded-For headers to work around it.

Any ideas are welcome. Anyone willing to help is welcome.

Goals if this should be:

  • Get a good feeling for the current database usage of lemmy
  • Optimize Statements and DB Layout
  • Find possible improvements by caching

As your loved core devs for lemmy have large Issue Tracker backlog, some folks that talk rust fluently would be great, so we can work on this dedicated topic and provide finished PR's

Greatings, Loki (@tbe on github)

First of all: I'm posting this from my .ml alt. Because i can not do it from my .world main. That i can't do it, i found out just because i was waiting for a response on a comment where is was sure that the OP would respond. After searching, i found out that my comment and my DM's never where federated to .ml.

So, that said: I'm all for defederating bad instances, i'm all for separation where it makes sense. BUT:

  • If an instance is listed on join-lemmy, this should work as the normal user would expect
  • We are not ready for this yet. We are missing features (more details below)
  • Even instances that officialy require applications, can be spam instances (admins can do what ever they want), so we would need protection against this anyways. Hell, one could just implement spam bots that talk directly federation protocol, and wouldn't even need lemmy for this ...

Minimal features we need:

  • Show users that the community they try to interact with is on a server that defederated the users instance
  • Forbid sending DM's to servers that are not fully federated

Currently, all we do is: Make lemmy look broken

And before someone starts with: "Then help!", i do. I do in my field of expertice. I'm a PostgreSQL Professional. So i have build a setup to messure the lemmy SQL performance, usage patterns, and will contribute everything i can to make lemmy better.

(I tried rust, but i'm to much C++ guy to bring something usefull to the table beyond database stuff, sry :( )
