You’re right, that’s exactly what happened. If you look at the top of the trace, it says __handle_sysrq. Moreover, it’s in the sysrq_handle_crash. That gets called when a sysrq combo is pressed.
You don't. Seriously. The point of an ergonomic keyboard is to touch-type. You won't learn to do that if you look at your keyboard.
Print your keyboard layout on a sheet of paper, and hang it next to your monitor. Now when you want to type a character, look it up on your sheet, and without looking at your fingers, type it. Try to remember the position like "left index finger, two lines above the rest line".
You still need all the physical space that two PCs require except for the box which is only a small part of it. You still need all the peripherals for two people and once the 3060s are in it the power difference will be negligible between one or two PCs. On top of that you have all the inconvenience and problems that using in multiseat brings. Network gear is dirt cheap and maintaining two PCs is less hassle Vs this too.
Personally I think at the end of the day you’re better off with two PCs even if the second one is a cheap second hand one. Especially since I assume the GPUs mean they’re planning on gaming on it.
When you have like 30 kids in a class and a limited budget then yeah, makes a lot of sense to come up with solutions like this.
For these two though if I knew them I’d just straight up give them a second PC for free to save them the hassle. You can do amazing things with refurbished PCs when budget and space constraints are a problem.
Not only for saving money, as when we upgrade the PC, I’m going to be able to sell off most of the components that get replaced, but space savings is also a big part of it. We’re going to be buying an RV to live full time in soon, and the less space it takes up, the better.
Plus, we have used it in this configuration for almost two years now, and it has worked without issue (EasyAntiCheat doesn’t play nice, but we don’t play many games that use it anyway). And honestly at this point, I kind of enjoy the challenge lol
You could have a look at ex-business slimline PCs or laptops if two cases are out of the question. They’ll take up less space overall than the typical PC case and are usually pretty power efficient. The former can also be upgraded if you are careful with what you choose and find the right slimline GPUs to fit in said cases. This is what I used to do for my kids particularly with ex-Dell PCs.
The thing is that you’re not going to get a whole lot for your old parts, certainly not more than the benefit you gain by having a second PC, as by the time you sell it the parts would have depreciated in value quite a lot. But, it’s neat I guess that PCs allow you to do stuff like this even if it would result in a bit of frustration.
I haven’t used it yet personally, but I would bet as soon as Debian/Ubuntu LTS/CentOS/openSuse/other stable Linux distros get kernels new enough to it will be not just a btrfs killer, but a ZFS killer too.
The tiered write and read layers and SMR support put ZFS caching to shame.
Nobody uses SMR for live data anyway unless it’s in very particular circumstances.
Bcachefs is still at least a couple of years away from serious use. But sure, if it’s available and you have a good backup strategy you can use it today.
As for “years away” I agree. As my first post said people should wait till you can use bcachefs in the stable distros. Debian isn’t getting kernel 6.7 any time soon 😆. So years away is right in any case.
I think bcachefs addresses the reason why people don’t use SMR HDDs. (Aka changes resulting in cascading writes)
You could have a data pool with the following tiers.
Tier 1: SSDs
Tier 2: HDDs
Tier 3: SMR HDDs
With bcachefs you would only ever write to your tier 1 storage. In the background, as able, bcachefs would offload the data from the faster lower tiers to the slower higher tiers based on frequency of data access.
You would only ever read from the SMR HDDs and would never write to them. They act as a sort of async backing to your data.
Personally I would love a data pool with a few SSDs, backed by a few HDDs, backed by many SMR HDDs. You would save so much money just with good architecting.
Bcachefs should be a ZFS killer. All the features of ZFS with storage tiers being a superior version of ZFS’s L2arc with none of the DKIM kernel license incompatibility nonsense.
Damn, I didn’t think to include SMR drives when it comes to bcachefs. Your whole comment made me appreciate the whole concept under a whole new light actually, thanks!
Ah I was getting it confused. At one point Steam stored everything in ~/.local/share/steam and symlinked ~/.steam to it. Doesn’t appear to be the case on Ubuntu 22.04, though I used to use Debian and grab the .deb from Valve’s website. My bad! :)
No, .cache is similar to a temporary directory (or at least in theory) where important data isn’t supposed to be stored there, instead only temporary files that might speed things up (e.g. images in a browser or thumbnails in a file manager). In this case it looks like all of my AUR packages had their source files cached, which added up over the ~1.75 years that I’ve been running this distro
I appreciate KDE for being a comprehensive toolbox that will let just about anyone craft the mouse-driven GUI of their dreams given enough time and effort. I appreciate GNOME for its bold and unified vision, which isn’t afraid to cull features or embrace innovation.
In what sense do you mean “faster” though? If you mean more performant, I haven’t experienced that – both desktops are extremely responsive.
May I ask why you, as a beginner, specifically chose one of those distros instead of more “mainstream” ones?
Puppy Linux’s main use-case is to be a live ISO, that doesn’t need to be installed to run. It doesn’t mean it’s not a good idea to install it, but I think if you want to use an Ubuntu derivative, there are better options for a beginner like Pop or Mint that would let you install a lightweight desktop environment like XFCE, LXDE, LXQt and so on.
Alpine Linux is specifically designed to avoid all the core system tools that are pretty much universal on most other distros like glibc, systemd or GNU tools and libraries, which will make your life hell as a beginner if you need to troubleshoot anything as most “universal” documentation like the Arch wiki would be at best partially relevant, at worst useless.
Like the others, I suggest you stick to a distro designed for desktop use (Ubuntu, Fedora etc), you’ll have a much easier time.
If you really want to go with something closer to “scratch made” I’d recommend Arch. Its documentation is killer and you can build a system suited to your requirements.
Nix packages arent containerized by default. But since every depenedency is clearly defined. there are tools wrap packkages using bublewrap, or tools build layered docker imahes
Great thanks! So Fedora+Nix (maybe some hacky way to symlink it to /var/nix on every boot and it can run on Atomic too)+bubblejail (there is a COPR now for use in secureblue) could be a great setup!
Any info about namespaces? Hardened kernels block these for valid reasons. Flatpaks can use bubblewrap-suid, Podman is supposedly not compatible (not sure about that)
