cultural reviewer and dabbler in stylistic premonitions
only hobbyists and artisans still use the standalone carrot.py that depends on peeler.
in enterprise environments everyone uses the pymixedveggies package (created using pip freeze of course) which helpfully vendors the latest peeled carrot along with many other things. just unpack it into a clean container and go on your way.

The canonical documentation is https://www.kernel.org/doc/Documentation/filesystems/proc.rst (ctrl-f oom) but if you search a bit you’ll find various guides that might be easier to digest.
https://www.baeldung.com/linux/memory-overcommitment-oom-killer looks like an informative recent article on the subject, and reminds me that my knowledge is a bit outdated. (TIL about the choom(1) command which was added to util-linux in 2018 as an alternative to manipulating things in /proc directly…)
https://dev.to/rrampage/surviving-the-linux-oom-killer-2ki9 from 2018 might also be worth reading.
How to make your adjustments persist for a given desktop application is left as an exercise to the reader :)
I’m not sure what this comic is trying to say but in my recent experience a single misbehaving website can still consume all available swap at which point Linux will sometimes completely lock up for many minutes before the out-of-memory killer decides what to kill - and then sometimes it still kills the desktop environment instead of the browser.
(I do know how to use oom_adj; I’m talking about the default configuration on popular desktop distros.)
404 Media neglected to link to her website, which is https://ada-ada-ada.art/
does your resume include a sokoban clone?
that flag is upside down 🤘
keep it steady? did you neglect to install the shock absorbing plate?
I think it depends which side of the debate one is on?

Hint: this expression is a valid timestamp. Use 'systemd-analyze timestamp "tomorrow"' instead?

(It checks out.)
Surprisingly its calendar specification parser actually allows for 31 days in every month:
$ TZ=UTC systemd-analyze calendar '02-29' && echo OK || echo not OK
Original form: 02-29
Normalized form: *-02-29 00:00:00
Next elapse: Tue 2028-02-29 00:00:00 UTC
From now: 3 years 4 months left
OK
$ TZ=UTC systemd-analyze calendar '02-30' && echo OK || echo not OK
Original form: 02-30
Normalized form: *-02-30 00:00:00

Funny that blog calls it a “failed attempt at a backdoor” while neglecting to mention that the grsec post (which it does link to and acknowledges is the source of the story) had been updated months prior to explicitly refute that characterization:
5/22/2020 Update: This kind of update should not have been necessary, but due to irresponsible journalists and the nature of social media, it is important to make some things perfectly clear:
Nowhere did we claim this was anything more than a trivially exploitable vulnerability. It is not a backdoor or an attempted backdoor, the term does not appear elsewhere in this blog at all; any suggestion of the sort was fabricated by irresponsible journalists who did not contact us and do not speak for us.
There is no chance this code would have passed review and be merged. No one can push or force code upstream.
This code is not characteristic of the quality of other code contributed upstream by Huawei. Contrary to baseless assertions from some journalists, this is not Huawei’s first attempt at contributing to the kernel, in fact they’ve been a frequent contributor for some time.
Wasn’t Huawei trying to put a Backdoor into linux?
as far as i know, that has not happened.
what makes you think it did?
After a minute of research I’m inclined to believe Godzilla egg-laying only happened in Roland Emmerich’s 1998 film.
Here is some contemporary reporting about it: https://www.chicagotribune.com/1998/05/19/godzilla-lays-an-egg-does-this-surprise-you/
Big, buff and bodacious, he’s so cool he can even reproduce himself–or herself. Turns out, Godzilla’s a hermaphrodite.
Consistent with the mythology, this giant lizard is a mutant by-product of nuclear radiation. As the only member of its species to have survived a bomb test in French Polynesia, Godzilla must assume male and female reproductive functions to maintain the lineage.
Why Godzilla feels compelled to travel all the way to Manhattan to lay its eggs is a mystery not clearly explained in the script, but, like any Sinatra fan, the monster probably thought, “If I can make it there, I’ll make it anywhere.” So, it was off to New York, New York, where–like the Knicks–the creature lays a lot of eggs in Madison Square Garden.

The headline should mention that they’re breaking 22-bit RSA, but then it would get a lot less clicks.
A different group of Chinese researchers set what I think is the current record when they factored a 48-bit number with a quantum computer two years ago: https://arxiv.org/abs/2212.12372
I guess the news here is that now they’ve reached 22 bits using the quantum annealing technique which works on D-Wave’s commercially-available quantum computers? That approach was previously able to factor an 18-bit number in 2018.
🥂 to the researchers, but 👎 to the clickbait headline writers. This is still nowhere near being a CRQC (cryptanalytically-relevant quantum computer).
Lets Enhance is a pretty great supercut, but nothing beats the original Blade Runner scene.
