Seems like an interesting effort. A developer is building an alternative Java-based backend to Lemmy's Rust-based one, with the goal of building in a handful of different features. The dev is looking at using this compatibility to migrate their instance over to the new platform, while allowing the community to use their apps of choice.

I think rust is a very pragmatic choice, lemmy is decentralized, the security benefits are a necessity when it comes to self hosters donating hardware

Java is also memory safe

After working in java for over a decade, I will never use another garbage-collected language if I can avoid it again. I still have nightmares about debugging memory build-ups and having to trace down where to do manual garbage collection. I remember my shop eventually just paid for 32 GB ram servers, and java filled those up too.

Rust doesn't have these problems because its not a garbage collected language like java or go, and has an ownership-based memory model that's easy to work with.

Is that still a problem in newer java versions? I have to admit I have only written simple things in java.

Garbage collection is by nature imperfect, its impossible for it to always be correct about when and what things to free up in memory. The best option is to not use a garbage collected language.

Wow. It's amazing that anyone ever got anything to work in java. Must have never got used for anything

Ah yes, that explains the log4j fiasco

That wasn't a memory safety issue, that was a what the fuck were you thinking design issue. It would have been batshit in any language
