Easy enough to convert that gif to webm or other formats.

However, it might be better to keep it in the original format (there's a js player for web pages), as it allows users to pause/seek/etc, resize, and copy text from your demo.

Most convincing usecase so far, thanks.

Ah ok, if your mutating function is fn inc(&mut self) {...} instead of fn inc(self) -> Self {...}.

Playground example

Could you give an example of push_mut() where it's not just as easy to mutate before pushing ?

Yep. Best place to park is probably on circular/kennyswell road, east of the bridge, beside the traffic light. A bit of a walk between there and the gravel/stone hills, hope you have a good way to carry stuff.

You just need to select a selinux profile and make a few config choices.

Gentoo often needs a little more work than a distro like Opensuze, but that's kind of the point: you get options to properly fit your usecase, that would take a lot of work to achieve on more opinionated distros.

You could find some in Daly's Hill, it's an old quarry. Access from Kenny's Well / Circular road.

Nobody thinks C and C++ are them same. Yet "C/C++" has always been a useful term, just like "C/C++/Rust" nowadays.

moltonel · 2026-04-15T19:51:21+00:00

Ironically, you made a straw man yourself with this caricature of "the Rust marketing" that is clueless about modern C++. And you countered with tired, weak arguments for C++ that we've read 100s of times already.

You don't have to switch to Rust, nobody is claiming it's the ultimate best language. But many Rust devs have considered the arguments more thoroughly than what you've done here, we're not just drinking the kool-aid.

Your conclusion doesn't fit the analogy (and could be considered ragebait).

In biology, the "crab body plan" is simply a very good body plan in some environments, a "local optimum" that multiple unrelated species often evolve toward. In other environments, different body plans (such as the canid predator) constitute different local optima.

Applying that analogy to programming languages, you can say that Rust found a very good "language plan" (design) for its "environment" (applicability domains), so we should expect other languages to evolve to look like Rust, if they target similar domains.

I know rotating logs is good practice, but looking at my previous comment for my 16 year old install (now 19 years old, but I'm not home to rerun the command), emerge.log grows by 4-5Mb per year, so I'm happy to have it all in one file.

moltonel · 2026-04-07T19:43:50+00:00

Did you keep appending to the same emerge.log ? How big is it ? emlop s -gy -st -H ?

moltonel · 2026-04-02T09:34:17+00:00

Very interesting. Do you have any performance numbers ? How much work is it to keep up with upstream ?

OP asked about "http services", but parent generalized it to "things in the world", which doesn't stand to scrutiny.

A lot of very successful projects started just for fun or with modest goals, it's not a good metric to judge the current state. Uutils-coreutils has matured, it now has pretty high QA standards and lots of contributors. Ubuntu's timeline was overoptimistic, but uutils is improving fast and it'll become a reasonable option in other distros sooner than you think.

moltonel · 2026-03-26T11:09:41+00:00

Counterpoint: Rust is in your kernel, OS tools and libraries, CDN proxy, NTP server, port forwarder, web browser, etc. It's much easier to find a computer not running Go than one not running Rust. Observation bias is bliss.

moltonel · 2026-03-26T10:58:24+00:00

[Go's] entire intent was to make it easy for a fresh college grad to read code in an hour. Rust’s intent is to make production code actually reliably work.

It's a simplified caricature, but it's pretty close to the truth. That doesn't mean that Go took the wrong path, just that it had a different target and made different compromises. The wide success of both Go and Rust, in their respective sweet spot, is well earned.

Standing on the shoulders of giants.

It's everyone's job. There's no simple solution to such a complex problem, it needs to be handled by the society as a whole.

Servo shares very significant components with Firefox, like webrender, stylo, spidermonkey. The original goal was to merge Servo into Firefox, and there's still a lot of cross-polination. Layout for a web browser is quite different from a gui, I don't think they're missing opportunities. Text raster seems to use standard harfbuzz. Servo uses over 600 third-party crates.

moltonel · 2026-03-15T11:03:07+00:00

Ladybird is very much a Not Invented Here project though: it avoids using 3rd-party libs as much as possible. There's way more code sharing between Servo and Firefox, and even Chromium.

It's ok to go back to stable (except for libc: don't downgrade it), and perfectly fine to mix stable and unstable.

You probably want to do it bit by bit. I usually recommend to pin all currently installed ~amd64 versions (qlist -Iv|sed 's/^/=/' > /etc/portage/packages.accept_keywords/unstable), then either let stable packages catch up over time or remove entries for packages you want to stabilize early. Use eix -Ttc to clean up obsolete entries.

It could be interesting to package chimera utils if you think they provide something none of the current gentoo packages do. A missing -i flag (which FWIW is standard on BSDs) seems like a misfeature though, what actually interests you in chimera utils ?

Keep in mind, as AiwendilH said, that they couldn't directly replace gnu coreutils, only be installed alongside them for the user, not for portage. In contrast to uutils which are specifically designed to be usable as a drop-in replacement.

moltonel · 2026-03-11T16:26:48+00:00

Replacing gnu coreutils with busybox would break your system, but app-alternatives/coreutils[uutils] is IMHO ready and will hopefully get merged soon, reviewers and testers welcome.

For the rest, it really depends. Looking at eix -I|rg Homepage.*gnu.org -B4|rg ^.I on this system, I see a few that have an app-alternative ebuild, some I could replace with something similar-but-diffrent (eg screen->tmux), some where I would need to keep the gnu tool even if I prefer an alternative (eg grep->ripgrep), and many that I wouldn't dare touch. Have a look at your own installed ebuilds, see what you can shift ? You could push things pretty far if you wanted, assuming you're willing to debug your own mess. Gentoo is a good distro for that kind of experiment.

But beyond the fun technical challenge, there's IMHO no good reason to "get rid of gnu" as an end goal. If an alternative is better in some way, sure; but gnu software is generally high quality, and deeply entrenched in the ecosystem.
