Today I learned about Sublinks (here), an open-source project that aims to be a drop-in replacement for the backend of Lemmy, a federated link aggregator and microblogging platform. Sublinks is designed to be initially API-compatible with Lemmy, allowing existing Lemmy clients, such as Lemmy-UI, to integrate seamlessly.
The project is written in Java, which may introduce some overhead but is chosen for its maintainability and familiarity among a wider pool of developers. The Sublinks team prioritizes a more inclusive and less toxic development environment, and the project has already attracted more developers than Lemmy.
While Sublinks is starting with 1:1 compatibility, future plans include implementing additional features that the Lemmy developers have not pursued. This could lead to a divergence in functionality between the two platforms as Sublinks evolves beyond its initial compatibility phase.

About
Sublinks, crafted using Java Spring Boot, stands as a state-of-the-art link aggregation and microblogging platform, reminiscent yet advanced compared to Lemmy & Kbin. It features a Lemmy compatible API, allowing for seamless integration and migration for existing Lemmy users. Unique to Sublinks are its enhanced moderation tools, tailored to provide a safe and manageable online community space. Embracing the fediverse, it supports the ActivityPub protocol, enabling interoperability with a wide range of social platforms. Sublinks is not just a platform; it’s a community-centric ecosystem, prioritizing user experience, content authenticity, and networked social interaction.

Sublinks is free, open-source software, meaning no advertising, monetizing, or venture capital, ever. Your donations directly support full-time development of the project.
I can understand the argument about more developers knowing Java (right now) and the controversy of the current main lemmy devs.
However for maintainability, I really don’t see it. Java has the billion dollar mistake with null references, forces you into an object oriented programming style and uses exception-based error handling, which is far inferior to errors as sum types like in Rust.
Often when Rust compiles, it works. This is a big strength when maintaining a large system. You can’t say the same about Java.
Lastly, Java doesn’t seem… Future-proof if you can call it that. It’s certainly an older language and it’s not likely to keep getting bigger. Rust is still growing a lot and is being adopted extremely heavily by the largest technology companies. It’s not unreasonable to think that there will at some point be more Rust devs than Java devs. Though that day could still be a long way off, to be fair.
None of these are a problem to experienced Java developers however, of which there is a huge ocean. Compared to a relatively tiny handful of Rust developers that also can get very highly paid industry jobs that keep them busy, so there’s even less of them available for hobby projects.
I can totally see it. Makes perfect sense in fact, you want people to help with development, you cast the widest net possible.
You’re kidding, right?
That is true, if you develop your java application correct, then you have no issues of any kind.
If you just never make any mistakes you’ll live a mistake free life.
It’s more that you can avoid many mistakes by programming defensively and having good discipline. For example, you can avoid many memory allocation if you follow RAII and use smart pointers.
Null references can be avoided by avoiding using null (and prefer using optional where it makes sense).
No issues of any kind? That’s absurd. The idea that you can “just” write “correct” code in any language and then you won’t have “any issues of any kind” is not any developer’s experience ever. Humans are just not reliable enough for that.
Yeah because of that i said IF you develop your java application correct…
If that is correct, than you have no issues of any kind. That statement is correct. But like you said, no one is perfect, but rust would be a more difficult language than java and less documented. For a stable, predictable and reliable software your programming language needs maturity, stability and a community to support it. Most of it rust doesnt have.
Okay but if you develop your Rust application correctly, then it’s obviously also correct. It doesn’t matter what language you use then.
That is just like, your opinion, man. I disagree. I’d rather not have null references and exception-handling if I was going for stability. Rust also has very nice documentation.
Okay, Rust is not as old as Java. This is true. But at this point, you cannot say that Rust is immature, unstable or doesn’t have a community.
The community online is huge, bigger than most other communities. If you want a number, see for instance the number of active users on /r/rust versus /r/java. I checked it now and it was 1096 versus 195. Nobody is hyped about Java any more, it’s an old language that many people don’t like. Check also for instance how many people like Java or Rust in the StackOverflow developer survey. ~87% of Rust users love using Rust while only ~46% of Java users love using Java - that means that there are more Java devs that would rather not use Java than Java devs who want to use Java!
Rust has very strong backwards-compatibility guarantees (just like Java). It’s very stable and things mostly “just work” if it compiles (unlike Java).
I would call Rust much more reliable than Java, and I think most people who have tried both would agree. Exception-based error handling just makes it notoriously difficult to cover all error cases.
Anyways m8, unless this somehow sways you I think we need to just agree to disagree. I would encourage you to actually try the language and see for yourself and see what I mean though.
The dude ?

Well time will tell. As far as I can see on https://github.com/sublinks/sublinks-api/graphs/contributors it really doesn’t look like more than two active developers right now… So not any better than Lemmy.
Also, when it comes to hosting stuff as volunteers, server costs are actually quite important, as its basically 100% of the expenses. So Rust’s efficiency is actually a more significant advantage than you may think.
Theres more than just the api repo and pull requests are squashed in some of them making it show as less
I mean, the same is true for Lemmy.
Java is already mature enough and i dont think the current smaller-medium instances experience that lemmy is on 100% cpu allways, so we can expect that it is a bit less optimal, but not before 5% cpu and after it 100% cpu, lemmy is a mess in performance, 0.18 instances gets ddosed by dead 0.19 instances, that retry always failed federation. So lemmy itself is the danger here.
When it comes to servers, memory is often the pricy point. And Java is a lot more memory-hungry than Rust.
Good, then find some guys to develop lemmy faster, reliably and bigger. With lemmys pace of features, it will be taken over by faster developing platforms, where they can have more and more features ready and deployed where the lemmy devs still wait until they get enough donation to implement any crucial feature.
Sublinks decision was based on: How fast and reliably can they build a lemmy backend replacement, java is the only possible option there. There are many devs, Language is mature, reliable and not a hipster language like rust.
Of course if they did that in rust they would be same level, but then would be the question why not contributing to lemmy directly.
If performance and memore is so dramatically NASA rocket computer limited, than why not use assembly. Its the fastest, memory efficient and speaks directly to the computer.
Well, we’ve yet to see that. But I mean if it does then… great? I just don’t believe it will right now. I don’t think just switching the programming language will have such a large effect as you expect.
You really can’t call something hipster when it is being adopted by the largest technology companies in the world and is even being used in the Linux kernel. That’s not what hipster means.
I didn’t say it was “NASA rocket computer limited”, I just said memory matters for price. And it does. This reads to me like you are frustrated and it comes across as a bit snarky and sarcastic. If we are actually to talk about programming language pros and cons, then at least let’s talk about it genuinely.
