För att se poster från någon i Fediversum måste personen, organisationen eller tidningen följas, Dvs en måste följa deras konto. Detsamma gäller än så länge BlueSky men då det senare ägs av ett kommersiellt företag med vinstkrav är det inte troligt att det kommer att förbli på det viset.

Variable refresh rate (VRR) allows your display to match the framerate of an image source, such as a game — and doing so prevents screen tearing. Support for VRR has been added to the cosmic-comp compositor and Displays Settings. You can set VRR to be either always on or automatic, which will enable VRR for fullscreen content.

memory leak fixes,

But muh Rust??

Rust doesn't prevent memory leaks. You can do that in every language

Back when I was a wee bit Java noob, I was trying to write a RuneScape bot to play Soul Wars. I had a basic recursive pathfinding algo for figuring out how to walk around the map, but it blew out of memory very quickly (each tile has 4 options, do that recursively, etc). So I added caching. Anyways, I never cleared the caching. So after 20 minutes of running the script, you had like 2GB of allocated RAM calculating the best path from any 2 tiles in the minigame.

Great times. No amount of language safety features would have saved me from that stupidity.

Especially if you have to use unsafe libraries from C, or use any unsafe block at all to do low level programming or for performance.

in reply to thingsiplay

naonintendois

in reply to thingsiplay • 1 year ago • •

You don't need unsafe. Just keep pushing to a vec and never remove anything. Memory leaks are more than lost memory allocations. You can even have them with rc/arc cycles

Yeah. Lot of people also use Ai generated code... so...

I have tested if clippy would warn me with a simple example (generates 6.7gb memory usage, be careful not to crash your computer if you add another 0...), while I watch with a system monitor (in KDE):

use std::thread;
use std::time;

fn main() {
    let mut vec = Vec::new(); // Create an empty Vector.

    for number in 0..900000000 {
        let bign: i64 = number * number;
        vec.push(bign);
    }

    thread::sleep(time::Duration::from_secs(10));
}

I used the pedantic option of clippy and the only thing it complained was about the notation of the number...:

$ cargo clippy -- -W clippy::pedantic
warning: long literal lacking separators
--> src/main.rs:7:22
|
7 |     for number in 0..900000000 {

Surely that's not a memory leak, that's just the program using a lot of memory intentionally

in reply to naonintendois

flashgnash

in reply to naonintendois • 1 year ago • •

Thought the whole point was that it forced you to handle memory properly and automatically released things when they go out of scope

What kind of situation can cause a memory leak in rust

in reply to flashgnash

naonintendois

in reply to flashgnash • 1 year ago • •

You can have a memory leak when items are still in scope in some loop or when you have a reference count cycle. The latter happens with the Rc/Arc types in rust.

An example for the former can be a web server that keeps track of every request it's ever received in memory. You will eventually run out of memory. But you did not violate any memory rules (dangling pointer, etc.). Memory leaks can be caused by design issues.

in reply to naonintendois

in reply to naonintendois • 1 year ago • •

That doesn't fit the definition of memory leak in my mind, had thought a memory leak was specifically when the program completely loses track of memory

in reply to flashgnash

MoonMelon

in reply to flashgnash • 1 year ago • •

That's one kind, and Rust's "ownership" concept does mean there's built-in compile time checks to prevent dangling pointers or unreachable memory. But there's also just never de-allocating stuff you allocated even though it's still reachable. Like you could just make a loop that allocates memory and never stops and that's a memory leak, or more generally a "resource leak", if you prefer.

Rust is really good at keeping you from having a reference to something that you think is valid but it turns out it got mutated way down in some class hierarchy and now it's dead, so you have a null pointer or you double free, or whatever. But it can't stop the case where your code is technically valid but the resource leak is caused by bad "logic" in your design, if that makes sense.

So... there will be Alphas 5 and 6. And we got Alpha 4 a week late, compared to the old release schedule of the last Thursday of every month. And a lot of the things that were meant for Alphas 3 and 4 were pushed back. I hope that System76 doesn't encounter more features that push things back further (the way VRR seems to have done), for their own sake. That way, they can keep up a lot of hype around the Betas and the release of Epoch 1.

in reply to theshatterstone54 • 1 year ago • •

That is normal in software development. System76 thinks that they will reach v1.0 early next year, but in reality, this won't mature for another 2 years or so.

theshatterstone54

in reply to Eugenia • 1 year ago • •

At their self-imposed rates of 1 new Alpha at the last Thursday of every month, and assuming only 2 Betas, and assuming they can get Alpha 5 done in December, we're looking at the end of April for release, though I'd realistically expect Epoch 1 at the end of June or July, or maybe even after that.

This is normal in Software Development.

I know. I'm a CS student, but they are still in a pretty early stage of their project and don't have anywhere near the technical debt or size of projects like Plasma or GNOME, and as such, I think they should still be able to keep on going at a pretty fast pace.

virtio-win question

Final edit: I got all the Linux stuff right but made a dumb mistake generating the image on the Windows side. Watching the VM boot right now. Thanks to all for your support!

cross-posted from: slrpnk.net/post/15860280

Contemplating Fedora Kinoite for work daily driver. Need to prove that I can virtualize an existing physical Windows 11 machine. Using Bazzite on a personal laptop as a host test bed.
Test host seems to be set up correctly. I layered the packages in the virtualization group, layered virtio-win (from downloaded rpm package), added my user to the libvert group, and enabled libvirtd. After a reboot or two, I can connect with the Virtual Machine Manager and define my VM.
On physical machine I used Disk2vhd to generate a vhdx. Moved that file to the test host and converted to qcow2. Copied disk image to /var/lib/libvert/images and added it as my drive image when I defined the VM.
VM starts but will not boot. Stupid question: Should I have install

I don't get this comment. Again, the virtio-win is an ISO that's easily mounted on a qemu (whether libvirt environment or not, which is not required, it just helps making the qemu configuration easier), which comes with several virtualized drivers that accelerate the windows experience quite a bit.

Changing the storage driver is complex on plain qemu (I don't think it's easier through libvirt just because the heck of it, the issue is the windows guest), first one need to run qemu with a dummy storage driver using virtualized driver, so that windows detects it. On the guest one needs to install the driver for the discovered storage from the ISO, then reboot and the dummy disk can go away and windows will find a driver for the main disk). Other drivers like the ethernet one, graphics cards, memory baloon, and other stuff need to change the corresponding driver manually, but no need for immediate reboots, but for sure several reboots are expecting while changing the windows drivers.

I no longer use a VM for windows, thankfully, but here it's a command line meant not to us

I no longer use a VM for windows, thankfully, but here it's a command line meant not to use a GUI qemu front end, but rather a Spice backend (requires virtualized special serial driver and special graphics driver):

Some investigation on your side is required if wanting to use spice (to add copy/paste cabalities on the guest, but perhaps that's not needed anymore with libvirt and some of the popular forntends from GTK/QT), and the QLX dirver needs to be chosen correctly since it depends on the windows version (there was one for windows 10, not sure if there's a 11 one).

Again, all this just to improve the windows guest experience. Some of this might have been made easier through libvirt, but the windows side of the drivers is a manual windows process, one driver at a time, and using virtualized storage is tricky on windows guests...

BTW I was setting a tap interface, with IP tables, because I found it to be the easier way to share my host VPN connection with the guest, without the need to establish a host and a guest VPN connection...

virtio-win allow for much better performance using virtualized drivers rather than plain emulation from qemu. Virt Manager doesn't offer windows guest paravirtualized drivers, that's on the guest side, and virtio-win ISO helps a lot with this.

Forgot to include the boot/system volume. It's a lovely time waster when you're dealing with disk images that are hundreds of gigabytes in size that have to be copied over the network. 😆

I'll add Disk2hvd screenshots when I get a sec.

Situation gets slightly more complicated if you had multiple drives in your system when you installed Windows, of course. Installer might put system volume on a different drive, so you'd have to image more than one drive to get a working system. Might get a little confusing as to which volumes should go in which image. There's a tool called GWMI that might help with that since afaik the volume guids don't show up in the Windows Disk Management snap-in.

Edit: The promised screenshot. In my case, I knew the volume labelled SYSTEM resided on the same disk as my C: drive. Probably don't have to include the recovery partition, strictly speaking, but I did.

Amnesty Report on Israel Genocide: Silence So Far from BBC News

Amnesty International released a “landmark new report” on Thursday 5 December. It concluded that Israel “has committed and is continuing to commit genocide against Palestinians in the occupied Gaza Strip”. But nine hours later, BBC News was still nowhere to be found. The UK’s state broadcaster apparently had nothing to say about “the world’s best known human rights organisation” judging a close British ally to be guilty of genocide.

DeepMind AI weather forecaster beats world-class system (this time with Bayesian statistics)

Google DeepMind has developed the first artificial intelligence (AI) model of its kind to predict the weather more accurately than the best system currently in use... The system, called GenCast, is described today in Nature.
Conventional forecasts, including those from ENS, are based on mathematical models that simulate the laws of physics governing Earth’s atmosphere... GenCast, by contrast, has been trained only on historical weather data...

So yeah DeepMind is fucking going at it again.

Interestingly the model architecture seems to heavily integrate Bayesian maximum likelihood estimation in addition to their usual GNN-based deep learning approaches, which I didn't know is even possible. Their methods section states "[o]ur innovation in this work is an MLWP-based Forecast model, and we adopt a traditional NWP-based State inference approach

I'm not super familiar with Bayesian methods though so if anyone can add some more information I'd appreciate it

It's hard to make a good weather forecast tool without theoretical elements incorporated in it.

I'm sure the model produces higher accuracy results on historical data. I read the abstract and it's not mentioned if they tested it on new data.

With ml, the most difficult part of the work is making sure not to overfit historical data. Is target have a less accurate model (on the training data) than a model that can be justified using theoretical reasoning. This way, I can be much more confident that it will work in the long run.

Let's see where this will go in the coming years!

Cant shutdown the system!(Fedora crashed)

I have been facing this issue since yesterday, but basically at some point the system becomes insanely slow, and the restart and shutdown options disappear from the menu, tty3-7 dont work, it freezes at the shutdown -now command(at which point I just manually cut the power(bad Idea I know)),

but today I stuck around as my system got insanely borked, eventually freezing up and giving me the screen above. the problem shows up after I wake it up from suspend but not always:
My system specs:

If you're on Android then you can use Termux (via F-droid) to get ssh capabilities. I think there is also a different iOS app, but I'm no expert on that OS, so I can't tell you its name. If you have a smart phone then you might have a ssh capable system after all

There are android clients, probably one for iOS as well. If you are getting OOM killed, you need to work out what is using all your memory. The OOM killer is pretty indiscriminate, and will murder processes randomly.

Maybe keep system monitor up and keep an eye on memory usage?

Old isn't necessarily bad. Also, as far as I can tell, distros are still patching 1.32. Based on my personal usage of LightDM and the fact that the project is still developed (based on commits to main), I'd say it's more of an "if it ain't broke, don't fix it" dynamic. As for security, the active development suggests the developers would respond if there was a vulnerability - a big if, considering its last CVE was in 2017.

Personally, I love LightDM - it has just enough features while mostly sticking to its name (I mean, you're probably using GTK anyway).

What about dmesg? if it's a hardware problem (and it looks like, but I may wrong) dmesg will print some usefull data

sudo dmesg -Tw

-T form human redeable timestamp and -w to follow (like tail -f)

Also, about that hard reset that you did, Linux magic keys are your friends if your are not facing a kernel panic, I have this key combo engraved in my head like a rune:

Press and hold Alt + PrtSc (not Alt+Gr) and then press only one time each (and while holding Alt + PrtSc) E + I + S + U + B

PrtSc maybe be SysRq in your keyboard depends on the manufacturer, architecture or how old it is. Also wait one or two seconds between keys when pressing EISUB.

The KMS timeouts almost make me wonder if the graphics chip is snorting some sort of crack.

Just to be safe, maybe try booting a live USB and see what happens. To be very sure, you could even try multiple distro/DE combos on the live disk.

If it's RAM, it should be easily replaceable on a laptop of that age. If it's the graphics chip, then it's probably time to find some other laptop. You can probably still press this to service in a homelab, though.

Responses ranged from the profane to the poetic, but one common theme was that despite its significant flaws, Twitter at its best was truly great … until it wasn’t.

Bluesky isn’t the ‘new Twitter,’ but its resemblance to the old one is drawing millions of new users

Bluesky, the microblogging alternative to X, is having a moment. A social media researcher explains why people are flocking to it – and why it isn’t likely to recapture the early days of Twitter.

It's going to get the most toxic elements from twitter. Social media just isn't cool anymore, like it was back when big sites first developed. They were already overwhelmed with users reporting each other almost as soon as people started moving there.

Once any site is big enough, marketing, trolls, influencers and propagandists move in too. Then it comes down to moderation to keep toxicity down.

“Science?” Yeah no.

I see these posts about how amazing things are at BlueSky literally every single day here. I got sick of it a long time ago but have mostly kept quiet because promoting alternatives to Twitter is a good thing.

However, I’m starting to think that taking up Lemmy airtime to promote another private, for-profit enterprise brought to you by the same guy who sold Twitter to an evil billionaire is perhaps not an approach worthy of extraordinary support.

Perhaps it would be better to link directly to the more scientific sources linked in the article:

The author of the article contributed to or co-authored those as well. The article is very general writeup, but there is real science here.

Canada Post strike is ‘highly disrespectful of Canadians’: minister. What's actually disrespectful is Canadian regime refusing to pay essential workers.

Canada Post strike is ‘highly disrespectful of Canadians’: minister

Labour Minister Steven MacKinnon said Canada Post and its workers' union are 'still very far apart,' as a nationwide mail strike nears its three-week mark.

Nice out of context quote. He's not saying the strike is disrespectful, rather than the lack of progress on resolving it.

The full quote isn't unreasonable:

“The parties are still very far apart, and that is in my view, among other things, highly disrespectful of Canadians who are suffering through this work stoppage, small businesses, people in rural and remote communities who rely on Canada Post’s services and these parties have to knuckle down and get the work done.”

It's plenty unreasonable because implies that workers who are very clearly underpaid somehow share equal responsibility here, or that they need to cave in because it's inconveniencing people.
