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.
Having a frontend rewrite seemed more critical than trying reimplementing the backend in a different language.
Remember, Lemmy had 4 years of development to iron out bugs, and this is essentially promising to make something in months that has a fully compatible backend to support all the third party apps, while adding features on top of what Lemmy has, and with a better front end with better mod tools to boot, with a complete rewrite of everything.
The scope of this project has planned for is already unviable. Suppose that Sublinks does reach feature parity to the current version of Lemmy, congratulations, the backend or mod tools is not something a regular user is going to notice or care about at all, all they will know is that suddenly, there are weird bugs that wasn’t there before, and that causes frustration.
And this project is going to get more developer traction because… Java?
I’d like to be proven wrong, but I’m very sceptical about the success of Sublinks, because it look like a project that was started out of tech arrogance to prove a point than out of a real need, I don’t work in tech, but the general trajectory of these kind of projects is that “enthusiasm from frustration” can only take you so far before the annoyance of dealing with mundane problems piles up, and the project fizzles out and ends with a whimper.
I have higher hopes. Java is three times more developers than Rust (https://www.statista.com/statistics/793628/worldwide-developer-survey-most-used-languages/), and you can see in this thread a number of people saying they could contribute as they know Java and not Rust.
Let’s hope for the best.
Java is a corporate language that most devs hate. Rust (Lemmy) is more popular as a hobby language that devs enjoy hacking in for fun.
Hm, Java is hated by devs, but still 2nd language on GitHub with 11,7% of the total code hosted, while Rust is number 13 with 1,8%?
https://madnight.github.io/githut/#/pull_requests/2023/4
How much of that 11.7% is 35-character class names?
I’m only half joking.
It’s by amount of pull requests, so the length of class names and other Java boilerplate doesn’t count.
Stockholm syndrome.
And even more, the Lemmy codebase doesn’t really have any important developers besides the two main devs: https://github.com/LemmyNet/lemmy/graphs/contributors.
Even looking at the contributions to something like Mbin, which has been around for much shorter, you already see 6 people with more than 50 commits, while Lemmy has one
https://github.com/MbinOrg/mbin/graphs/contributors
We have 13 contributors with Sublinks so far. I expect more will come after the announcement.
Java devs like you need to step away from the PC and stop assaulting the world with a terrible language. You should be ashamed of yourselves for inflicting decades of misery on the world.
Java will go the way of COBOL. The future is Nim.
You’re delusional if you believe people care about Nim. It has been around for 16 years and is still nothing in comparison to Java. Java won’t go anywhere and is here to stay.
Or, bare with me…it’s just a it o banter my son.
I don’t like Java either, but there’s no need to insult the developers for using a language they like.
Thank you
Who, who whooooooooooo dyou think you are?
“I’m right, and if anyone disagrees, it’s because they’re brainwashed”
There’s literally no possible way to argue against this type of logic.
The weight of my intellect is a heavy burden to bear.
Irrelevant
Typical Java dev attitude.
Thanks but I’m a network engineer, I’m just saying your argument is pointless, the majority of devs support a certain language. How they or you feel about it doesn’t matter one bit.
Removed by mod
Citation required, because strangely enough people whom I hear about complaining about Java never seem to be the good developers but the ones I wouldn’t hire
That’s bullshit, frankly
As a java dev, I can say that we hate working with java and love working with java at the same time.
Ah, an anime consumer. Explain to me why FMA:B is the greatest anime ever made?
fmab is another regular anime that’s overshilled.
Jesus H Christ.
Just peeking at the source code and it all looks like pretty standard stuff. Looks just like apps I’ve worked on at several jobs.
Is it sexy? No. But a lot of people have experience with this and could help develop.
Only time will tell if this project pays off though
I’m pretty sure Nutomic was a Java dev before starting work on Lemmy and learning Rust from scratch. That by itself should already speak volumes.
One-Up projects like this rarely ever turn out well, that’s from my own experiences. Even though this isn’t a popular view, I still think I’m right on this one, we can circle back in say, 6 months, to see if my predictions are right.
That is true, I used to be an Android developer and then learned Rust by writing code for Lemmy. Are you by any chance my new stalker?
And if we’re comparing the languages, the fact alone that there are no Nullpointerexceptions makes Rust infinitely better than Java for me. I also agree that this sort of copycat project will soon be forgotten. For example have you ever heard of Rustodon?
No, it was on that AMA you guys did months ago, and I remember things about people.
Very impressive! The only thing I can remember well are places.
what’s wrong with having null pointer exception?
Null is terrible.
A lot of languages have it available as a valid return value for most things, implicitly. This also means you have to do extra checking or something like this will blow up with an exception:
// java example // can throw exception String address = person.getAddress().toUpperCase(); // safe String address = ""; if (person.getAddress() != null) { person.getAddress().toUpperCase(); }
There are a ton of solutions out there. Many languages have added null-coalescing and null-conditional operators – which are a shorthand for things like the above solutions. Some languages have removed the implicit nulls (like Kotlin), requiring them to be explicitly marked in their type. Some languages have a wrapper around nullable values, an Option type. Some languages remove null entirely from the language (I believe Rust falls into this, using an option type in place of).
Not having null isn’t particularly common yet, and isn’t something languages can just change due to breaking backwards compatibility. However, languages have been adding features over time to make nulls less painful, and most have some subset of the above as options to help.
I do think Option types are fantastic solutions, making you deal with the issue that a none/empty type can exist in a particular place. Java has had them for basically 10 years now (since Java 8).
// optional example Class Person { private String address; //prefer this if a null could ever be returned public Optional getAddress() { return Optional.ofNullable(address); } // not this public String getAddress() { return address; }
When consuming, it makes you have to handle the null case, which you can do a variety of ways.
// set a default String address = person.getAddress().orElse("default value"); // explicitly throw an exception instead of an implicit NullPointerException as before String address = person.getAddress().orElseThrow(SomeException::new); // use in a closure only if it exists person.getAddress().ifPresent(addr -> logger.debug("Address {}", addr)); // first example, map to modify, and returning default if no value String address = person.getAddress().map(String::toUpperCase).orElse("");
I also was a professional java dev, and also had to use spring boot in most corporate environments.
I don’t wanna knock anyone’s re-write, because I know how difficult it is to dissuade someone when they’re excited about a project. But to me, starting a new project or doing a rewrite, is the best opportunity to learn a newer, better language. We taught ourself Rust by coding lemmy, and I recently learned Kotlin / jetpack compose because I wanted to learn android development. Learning new languages is not an issue for most programmers; we have to learn new frameworks and languages every year or so if we want to keep up.
This is potentially hundreds of hours of wasted time that could be spent on other things. Even if someone absolutely hates Rust and doesn’t want to contribute to the massive amount of open issues on Lemmy, there are still a lot of front-ends that could use more contributors.
it it common to announce a ‘major rewrite’ without having it complete?
i mean, at the moment, theres little to discern it from lemmy at the moment… why make a big public proclamation about it before you even touch the front end?
To get contributors to the backend?
i guess. i would think there are better avenues looking for devs though
Lemmy had 4 years to accrue technical debt and make foot-guns first-class features. A rewrite is probably exactly what it needs.
Have you read the source code? I’m not trying to be a smartass, I’m genuinely curious.
I have and if I’m honest I’m probably a little bit too harsh. I think the bigger issue is honestly the priorities of the dev team. There’s good reason that this project is focussing on moderation tooling.
What sort of moderation tools are you missing in Lemmy?
Some things that seem hard to argue with:
My own personal wishlist:
There’s some other stuff that I have seen PRs for and I do understand y’all are working hard. I appreciate the work you’ve done so far and the communities you’ve helped build. The Internet is undoubtedly a better place for it.
Dessalines is currently working on mod actions for Jerbia. Someone recently made a PR for moderator edits but it seems there was not enough interest and it was closed by the author. Better reports handling would be nice, but if you read the issue its not really clear how this should work. Private communities are on the roadmap for this year.
Karma is intentionally left out of Lemmy because it has many negative effects. Wikis make more sense as a standalone project, in fact Im working on something. Flairs are also potentially on the roadmap. For hashtags I dont really see the benefit as they would serve a very similar purpose to communities.
With regards to hashtags I think the utility is mostly in searching among similar things within a community. Suppose there’s a community that serves a purpose like r/askhistorians, stackexchange, or like what I’m trying to do over at !opencourselectures@slrpnk.net. In each of those cases, it is enormously useful to be able to search the community by subtopic. Obviously, this could be solved in other ways, but hashtags are probably the simplest to understand and implement.
Very excited to see the outcome of your Ibis project, but I think Lemmy native wikis would see significantly more activity. The easiest implementation I can imagine is a slightly altered frontend for communities marked wikis that also handle some well known syntax (like [[link]] popularized by pkm systems) for internal links. That is links to posts by the same name within a community.
Currently, I’m working on a lemmy bot that handles exactly this internal linking, and hashtag functionality, then builds a static site with support for github pages (so the end result is both a linked community and a seperate site), but I’d much rather have this functionality built into lemmy. To be frank, I’d much rather be trying to build this functionality into lemmy and if I wasn’t nearly certain it’d get shot down as out-of-scope, I’d probably be doing that.
I know you’re not particularly fond of growth based arguments for new features, but I sincerely believe that the thing that made reddit great in those early days was the tendency for communities to compile resources (particularly for niche and hobby communities). This gave the communities a certain depth that is nearly impossible with posts alone. If that were a first-class feature of Lemmy, I think you’d very quickly see Lemmy fill the niche that federated wiki projects and supplementary wiki services have so far failed to.
Then hashtags would have the same use as post tags on Reddit. I think thats a cleaner solution and there are plans to implement it.
Lemmy is already a very complicated project, and adding more functionality will only make it harder to maintain. Also there are lots of people who use wikis without Reddit, Wikipedia is one of the biggest websites in the world after all. So a Fediverse alternative is very much needed. Plus Lemmy and Ibis can federate in the future.
karma requirements and hashtags doesn’t seem right since the former will make people to farm karma for the requirements which is one of the reasons why newbies on reddit always dump post until they get a decent karma. lemmy is not a microblogging site, hashtags have better use in platforms like mastadon. post flairs should be implemented though.
Says who? Because that’s how the old platforms used it? I think we should really be moving past the direct influence of these corporate platforms and on the fediverse that probably means something of a well understood common language (like @user@instance or !group@instance). Hashtags were only ever a thing on twitter because the users just started using them and full text search was sufficient to handle it (this is more or less the position we’re in on lemmy). Direct support didn’t come till much later.
The ones on the Sublinks roadmap are interesting, for instance the warning system: https://github.com/orgs/sublinks/projects/1/views/7
There was also this list from a few months ago: https://discuss.online/post/12787?scrollToComments=true
True a warning system makes sense.
And you think that a rewrite would magically solve all those technical debts?
Magically no, but sometimes a clean slate is easier than a refactor. I’m speaking generally though, I’ve never looked at Lemmy’s code, and I’m not even who you originally replied to.
There are some projects that start because of “tech arrogance” as you describe the current situation. MariaDB, Git, LibreOffice are some of the most famous ones, but I’m sure there are more.
But does it have blockchain AI integration?
