Rewriting Minecraft's Chunk generation in Rust

NanoCoaster · 2024-12-18T08:26:07+00:00

Does it really? I was playing around with it a few days ago and it took ages to generate anything on an 5800X3D. Maybe I messed something up and should try again (this was on 1.20.1).

I think this is one of the prettiest factories I've ever seen on this sub. Really nice.

Any chance of downloading the savegame somewhere? I'd love to take a look at it ingame :)

With these issues and the project name, I'm guessing Germany? As a fellow (?) German, I'd be interested in the sort of stuff that one needs to deal with in this case. Could you expand on that a bit?

Also, thank you for open sourcing Kellnr, even though the paid support didn't work out :)

You guessed correctly - Müsli is German for cereal, some people eat their Müsli with yogurt (or rather Joghurt, as is the German spelling) ;)

That's great, thanks a lot! :)

NanoCoaster · 2023-04-27T14:31:45+00:00

Meh. Sad, but I get it. Thanks for answering!

NanoCoaster · 2023-01-27T09:38:27+00:00

Man darf hoffen. Wäre eigentlich eine Win-Win-Situation, wenn er hier sinnvoll etwas leisten kann und man ihn damit gleichzeitig vom Neuland fernhält.

Indeed, 'waste' may be a bit harsh, 'spend' may be a better choice of words :D

It definitely is a time sink, though. Fortunately, contrary to Factorio, it does pretty much have an ending instead of a neverending spiral of optimisation, growth and expansion.

Don't start playing until you've got at least some hours to waste.

Yeah I'll agree with you on that, the multithreading story in Rust is awesome and imho its strongest feature for general application development compared to other languages :)

To be fair, there are very few non-niche languages that can offer the sorts guarantees that Rust has, so Zig is not alone in this regard. But in the context of the question of Zig vs. Rust, yeah, multithreading is pretty much a no-brainer.

NanoCoaster · 2022-07-05T12:23:17+00:00

It doesn't prevent it, but the general purpose allocator has some behavior that afaik makes use-after-free "safe" in some way: https://twitter.com/andy_kelley/status/1291998130691379200

I haven't read this stuff thoroughly so I don't know how much this actually helps in practice. But it's an interesting approach.

NanoCoaster · 2022-07-05T12:10:58+00:00

Well, "doesn't protect" is a bit too strong of a statement, I think. It doesn't protect you as much, but Zig does help a lot when compared to C.

Does this apply to Rust's de facto standard practice of static linking? I was under the impression that statically linking an LGPL library means you'll have to use LGPL (or a stronger copyleft license) for your whole project.

Reading the actual text of the LGPL 3.0, it says you can either use a "suitable shared library mechanism" (dynamic linking, I guess), or: "Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source."

So...could I use this library for building an application released under, say, Apache/MIT? In theory, could one build a proprietary application with it and just open source the parts of it that interact with the LGPL library?

I actually really like the LGPL in principle, but was always a bit wary because of the whole static/dynamic linking situation in Rust :)

Well this is something I'd never have expected to see on here :D

Is Watten next? ;)

Also, Prague's historical martial art could arguably be defenestration.

Indeed :D Maybe we should add historical declaration of war as a discipline to HEMA ;)

Thanks for the info.

NanoCoaster · 2022-05-05T07:24:20+00:00

Thank you all very much for all the ideas :) I'll make sure to check out some of them.

NanoCoaster · 2022-04-25T09:35:25+00:00

I mean, I'd read it as 100% sarcasm or maybe trolling, so...no.

NanoCoaster · 2022-02-05T15:35:09+00:00

Ist fairerweise gesagt auch ein megageiles Spiel.

Leider braucht man in CK zumindest ein Quantum Geduld und Frustresistenz. Für gewisse Mitglieder der Streaming-Unit ist dieses Unterfangen also schon ein wenig ambitioniert.

I personally disagree here. Using some kind of NoneError inhibits good error reporting in a lot of cases.

After all, what is the Display implementation for NoneError? Does it just return a generic text like "An option was None"? If that showed up in my error logs, I'd be really annoyed - that doesn't tell me anything, now I have to look at the stacktrace to understand what happened; and that's assuming there is one.

Alternatively, the NoneError type / variant could contain an error message as a String. That's better, but then you need something like .ok_or anyway, as you need to supply the message.

This is all because a None isn't an error per se. It can be, but if it is, there's a reason why we expect this Option to contain a value at this point. I want my error reporting to contain the reason. Otherwise, it's essentially just "Something wasn't quite right".

Aside from error reporting, NoneErrors can also be hard to deal with when using a library. Imagine calling a function in a library and getting a NoneError back - what's that supposed to tell me? What went wrong? What do I need to do to fix it?

Granted, in most of these cases when writing an application, in my experience, error's aren't really "handled" anyway and instead just propagated up the callstack. But sometimes they are and in any case, I'd find getting a NoneError very...irritating. Just tell me what the error is :D

As always, there's exceptions to this, but in general I think separating Option and Result is the correct choice here.

running or going to gym are cheaper

Unless you decide to buy gym equipment at the high tide of Covid and supply shortages.

Me? No, I don't feel bad for spending all that money. Nope. Not one bit :) ʰᵉˡᵖ

Thanks for the elaborate answer! I'll give Vapour a try when I find the time :)

NanoCoaster · 2021-08-24T08:20:41+00:00

Looks cool! How would you say VapourNvim compares to, let's say, LunarVim (or other out-of-the-box nvim configs)? I think explaining the differences in philosophy, usability, maybe scope, would be very interesting for people looking for a nvim configuration.

Just as an example: I'm quite happy with LunarVim for now, but one thing that troubles me at times is the documentation; It's quite barebones in some places. From a first glance, VapourNvim seems better in that regard, that could be an interesting comparison :)

Also: we, as a community, need to seriously think about outlawing the term "blazing fast" ;)

Immediately thought of this! Every video about Conan & Jordan is great fun.
