After the (temporary) defederation announcement of earlier i checked the Lemmy repo to see if there was already a ticket on the federation limiting option like Mastodon's that people mentioned Lemmy doesn't yet have. Not only i didn't find it, i also saw that there's about 200+ open tickets of variable importance. Also saw that it's maintained mostly by the two main devs, the difference in commits between them and even the next contributors is vast. This is normal and in other circumstances it'd grow organically, but considering the huge influx of users lately, which will likely take months to slow down, they just don't have the same time to invest on this, and many things risk being neglected.
I'm a sysadmin, haven't coded anything big in at least a decade and a half beyond small helper scripts in Bash or Python, and haven't ever touched Rust, so can't help there, but maybe some of you Rust aficionados can give some time to help essentially all of Lemmy.
The same can be said of Kbin of course, although that's PHP, and there is exacerbated by it being just the single dev.
Even as someone with Rust experience, I found the experience of attempting to add a change to be frustrating. Aside from the fact that there's quite a bit of unidiomatic Rust (which I can't be too mad about, but does mean there are a lot of function signatures that just aren't what I'd expect and caused me some pain), the compile times for even small changes are long. After just changing a struct initializer, running
cargo checktook nearly a full minute, due to all the dependencies between the crates.
