Russian Air Force affiliated channel Fighterbomber commented on the attack on Belbek Air Base.

"There is no point in writing anything about Belbek.
Both the Ukrainians and us are lying. As usual. But the "truth" won't change anything. We need to learn. To the wounded recover, to the dead eternal memory."

Explain to me like I'm 10 years old: Is the Biden tariffs on electric vehicles, batteries, and solar panels coming from China motivated 100% by politics (and maybe racism), or is there some other (more legit) reason to do it?

@davidho anything that makes cars more expensive is a net positive for humanity, regardless of the motivation

If you're doing a lot of work in C/C++/Rust consider using sccache to cache compilations. It's easy to set up and will save you a lot of time and a huge amount of power.

https://github.com/mozilla/sccache

As an example this is just a couple of hours of work on Firefox, it saved me from re-running the compiler almost 90% of the time.

@shram86 this is a generic tool that works with all mainstream compilers and requires just a few lines of global configuration. After that it works completely transparently

Random linux question: Is there way to tie a keystroke directly to an action in a console? Not in a terminal emulator, mind you. I mean, I'm not running X or Wayland anything, the console.

I'm thinking of volume keys, etc.

gabrielesvelto,
@gabrielesvelto@fosstodon.org avatar

@mhoye you can create a custom keymap and bind commands to the keys you care about. The Arch wiki has some examples on how to do it: https://wiki.archlinux.org/title/Linux_console/Keyboard_configuration#Creating_a_custom_keymap

The shocking realization that - in spite of the way it objectifies its characters and the heaps of fanservice it contains - #BubbleGumCrisis passes the Bechdel test.

I love our users: I went over two bugs, one in Thunderbird where the user was trying to drag 5k contacts to the "To" field of a new email and the other in Firefox with the user trying to upload 100k files in one go to GDrive.

While these are extreme cases they should work. If we can handle them gracefully we can handle anything, so we should strive to make these cases work.

@Ryan for running a dekstop system OpenRC requires a bit more configuration than a systemd install, but it's usable and shouldn't pose too many issues

@mhoye it's particularly useful when you're making a raw image of the partition with ddrescue and compressing it

Here's another older #ps1 style #animation spruced up with polygon wobble and an extra layer of crunch

Low poly animation of a blue-haired girl in a drab sci-fi environment being interviewed by someone out of frame. The audio is taken from a Comedy Central skit featuring Hailee Steinfeld and Joshua Horowitz. The transcript is as follows: Voice: "Standard questions for you here-" Mynn: "Sure." Voice: "-these would be the usual ones we run by everyone: Have your parents ever been violently murdered in front of you?"

every year i find myself paying closer attention to the weather than the last. wonder what could be causing that. some kind of change in climate, maybe? nah. that couldn't possibly be it

@gabrielesvelto@fosstodon.org avatar

@eniko the world is changed. I feel it in the water. I feel it in the earth. I smell it in the air. Much that once was is lost, for none now live who remember it. It began with the forging of the Great Rings. etc...

@eniko cue Gandalf going "War has already begun" which is very appropriate whether you're thinking of climate change or actual violence in the world

I read an article about gender inequalities in Italy which stated that - among other things - less than 10% of Italian men clean the bathroom.

So this morning, while I was cleaning our bathroom, I've got the idea that we should make a percenter group of men who clean bathrooms, to lampoon the similarly named far-right groups.

Of course we'd go full testoterone-machismo about it, how it's the quintessential manly activity, and how getting rid of limescale and mold stains makes you a mega chad.

I’m planning air travel from Helsinki to Seoul with my child who is going to be two years old at the time of travel. I have no experience with air travel with a 2-year-old.

Finnair says that it‘s OK to bring a car child seat approved for airplane use. The EU even recommends doing so, but I gather it isn’t actually common. (Is it?) The standard number trail both from Finnair directly and via the EU regulation lead to https://www.tuv.com/landingpage/en/manufacturer-of-child-seats/ .

@hsivonen my kids always traveled on a regular seat, I've never been asked to use a car seat and never seen one on a plane in all frankness. That being said keeping a 2yo put on a plane is a big challenge, and I doubt a car seat would help much there

Memory errors in consumer devices such as PCs and phones are not something you hear much about, yet they are probably one of the most common ways these machines fail.

I'll use this thread to explain how this happens, how it affects you and what you can do about it. But I'll also talk about how the industry failed to address it and how we must force them to, for the sake of sustainability. 🧵 1/17

@kamstrup that was true for a while, then it was forked into PCMemTest by Martin Whitaker, and merged back with the memtest86+ codebase and now it's maintained by both the original author (Sam Demeulemeester) and the Martin Whitaker. The 7.0 major release dates back to this January.

@ali1234 this is very interesting, yeah that's another workload which ends up touching a ton of memory

gabrielesvelto,
@gabrielesvelto@fosstodon.org avatar

@dolske thanks Justin! With @pbone we were thinking of doing just that, statistically testing crashy machines to figure out if we could spot some bad memory.

gabrielesvelto,
@gabrielesvelto@fosstodon.org avatar

@lienrag @qqmrichter it's hard to tell apart a page that uses a lot of memory from a page that's leaking. What we're doing though is making sure that pages that use a lot of memory and which you aren't looking at get unloaded eventually, freeing the memory they're holding to.

@lolcat IIRC modern DRAMs have low-power modes which can be enable when utilization is low or none; I don't know if they can also shut down individual sections/banks but maybe they do? I remember reading about that as a theoretical possibility well over a decade ago so maybe yes

gabrielesvelto,
@gabrielesvelto@fosstodon.org avatar

@tommythorn one of the things we plan to do is running a brief, low-priority scan in processes that crashed. If we find some bad memory we'll notify the user and flag future crashes from their machine as low-value so we don't spend too much time looking at them.
