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.
PHP is hugely popular. People just don't talk about it because the developers that use it mostly keep quiet and do their work :)
Every time someone says PHP is dead, it lives for another year ๐ฌ
People were saying that PHP was dying when I started using it - that would have been around 2003 I think, with PHP 4.3. 20 years later, apparently it's still dying!
WordPress powers a crazy number of websites. I think around 35%? All of those sites are using PHP. I wouldn't be surprised if it was the most widely deployed backend technology across all websites.
According to this, WordPress powers 43% of the internet, when you think about it it's crazy!
