(didn’t read OP, didn’t keep up with chimera recently)

From the top of my head:
The init system. Usable FreeBSD utils instead of busybox overridable by gnu utils (which you will have to do because the former are bare-bones). Everything is built with LLVM (not gcc). Extra hardening (utilizing LLVM). And it doesn’t perform like shit in some multi-threaded allocator-heavy loads because they patch musl directly with mimalloc. It also doesn’t pretend to have a stable/release channel (only rolling).

So, the use of apk is not that relevant. “no GNU” is not really the case with Alpine. They do indeed have “musl” in common, but Chimera “fixes” one of the most relevant practical shortcomings of using it. And finally, I don’t think Chimera really targets fake “lightweight”-ness just for the sake of it.

No. This one is actually cool, useful, and innovative. And it tries to do some things differently than everyone else.

Not knowing about opt-in telemetry doesn’t convey lack of experience, or lack of (relevant) knowledgeability. Especially considering the fact that Arch purposefully keeps the existence of it low-key to avoid the possibility of pissing off anyone.

I was already an Arch user when that opt-in telemetry was introduced. And only heard about it because I was relatively active in Arch communities back then (relatively young, relatively new to Arch). If pkgstats were introduced two years later, I would have never heard of them. Because believe it or not, Arch is just a reliable OS, where you don’t have to interact with anything other than reading the odd announcement every other year. It’s not a “community”, or a “way of life”, or anything in that bracket.

The premise of the question is wrong, since it assumes a general preference.

If you’re asking 👉 this 👈 Arch user, the answer is “NONE”.

EDIT: The majority of users, especially experienced ones, don’t enable pkgstats. So such stats always end up in some form of self-selection (biased towards users who would use a DE in this case).

They know you can just do if ((age < 18)) in bash, right?

Or rather if ((10#$age < 18)) because age=021 would not be adult 😉 Hopefully, they protect against that at least.

(I had to double-check this stupid default is still a thing, since I moved to zsh many years ago.)

With GPU rendering, you should learn about GPU processing and memory usage too, not that it would matter much for such a use-case.

nvtop is nice for displaying all that info (it’s not nvidia-specific).

Also % CPU usage is not a good metric, especially when most people forget to set CPU frequencies to fixed values before measuring. And heterogenous architectures (e.g. big.LITTLE) make such numbers meaningless anyway (without additional context). But again, none of this really matters in this use-case.

A quick shallow look.

• Avoid single hard paths. Provide fall-backs. Make them all configurable. Use xdg (properly)…etc.
• Avoid .unwrap() or any source of panic!() for non-fatal things that can actually fail.
• Make non strictly necessary fields optional in you model, if that helps.
• Use .filter_map() and .collect() in your parsing code, instead of all the matches and continues in a for loop. You can use .ok()? to early-return with None on errors.
• And finally, since you’re micro-benchmarking, try speedy or borsh instead of bincode, unless you need the serde compat for some reason.

fun with flags (run it)

I gave this a quick look at 2X speed with a lot fast seeking, and my brain still hurts.

First of all, and concerning Rust, please familiarize yourself with the mem module and its functions at least. You didn’t even get near a situation where using unsafe{} was actually required.

Second of all, and concerning the task at hand itself, for someone who knew to make the distinction between bytes and chars, you should have known about grapheme clusters too. There are a lot of multi-char (not just multi-byte) graphemes out there. You can make a “Fun With Flags” 😉 segment to show that off (no attribution required). Just don’t do anything silly, and make sure to just utilize the unicode-segmentation crate.

sudo is NOT a part of coreutils. Anyone with basic *nix knowledge would have known this.

sudo-rs, as expected, is also NOT a part of uutils. And the projects happen to be very different in many aspects. uutils started from scratch as a hobby side-project, and it was developed from the start in idiomatic Rust. It can’t directly take anything from the GNU implementation anyway, as explained in their README. sudo-rs however is a funded effort to translate some C projects into Rust with as little unsafe{} as possible. Some of the code was directly translated from the original implementation. And if you look at the code in general, you will see that it’s rather low-level and looks more like C than Rust in many parts. Some of this is arguably necessary given the nature of sudo functionality, but not all of it.

Both projects do share the fact that they probably didn’t push for distros, Ubuntu or anyone else, to switch to either of them by default already, and both were probably surprised it happened this soon.

And yes, this exposure, negative as it may seem for now, is an unavoidable “teething” period, and it’s going to be of great benefit to both projects on the long run. Hopefully, Ubuntu users living on the edge wouldn’t face too much trouble meanwhile.

(I don’t use Ubuntu, but have been using sudo-rs by default for months.)

I get it – abstractions are cool. They’re supposed to hide complexity so we can focus on cooler stuff. And Rust loves that idea. Traits, generics, lifetimes – layer upon layer of “don’t worry about it honey.”

That’s such a fundamental misunderstanding of something so basic, that I almost had to stop reading.

zswap is not better than modern zram in any way. And you can set up the latter with writeback anyway.

But that’s not OP’s problem since “swap gets hardly touched” in OP’s case.

The point is compression.

• Use zram devices equal to the number of threads in your system.
• Use zstd compression.
• Mount zram devices as swap with high priority.
• Mount disk swap partition(s) with low priority.
• Increase swapiness:

     sysctl vm.swappiness=<larger number than default>
  

• Use zramctlto see detailed info about your zram disks.
• Check with iotop to see if something unexpected is using a lot of IO traffic.

Okay. I thought for a moment that you and everyone else were not on the same page.

zram file

what zram file?

Forgot to mention that I wasn’t exactly young at the time. We just didn’t have reliable broadband internet back then in my neck of the woods. So I had to download ISOs and save them in a USB thumb drive in a uni computer lab.

Early Mandriva with KDE 3.4 or 3.5 I think, but I can barely remember anything with clarity. It couldn’t have been bad though, since I haven’t used Windows on my own devices since 😉.

From my foggy memory, I think it was good for my then nocoder self, easy to use, stable, relatively lite, and had good looks.

I missed the Mandrake and pre-Fedora Red Hat era, but not by much.

With all the surface false analogies and general lack of solid knowledge in the comments here, I truly hope that at least half of them are LLM generated.

This is cool and lies within my area of interests.

One thing that is not clear is if there will be a way to do playback outside of custom players. If a stream can’t be trivially grabbed, and/or played directly in mpv (via ffmpeg library support or otherwise), this won’t be very useful for me.

It would also be interesting to see how the video streams are encoded, if the GOP size is forced to 1 and it’s all intra frames or not, and if it’s not, how synchronization after recovery (where FEC is not enough) is done.

Hopefully this gets posted again when the code is released.
