How do I find out where to look?
Program documentation first, Arch Wiki second, Gentoo third, surfing the web as a last resort, then ask the forum in the same order. The problem is that there is no universal way to log stuff to so I can’t really point out where to look.
git clone archwikiDoes that actually work ? 🤔Nice. Thank you!
Mostly journalctl.

I use Linux because I like to know that if my computer doesn’t do what I want, it’s my own damn fault (and not some corporation trying to screw me over).
I use Linux because when I encounter an issue there are numerous helpful forum posts and KB articles that cover it, even for really uncommon glitches. Whereas on Windows for even slightly obtuse errors, you just get the same base-level troubleshooting suggestions and AI listicles. Windows obscures actual useful information from end users which makes troubleshooting issues harder.
cough Canonical cough
I guess it is still “your own damn fault” if you use canonical ‘products’
Exactly. There’s something reassuring about it always being a skill issue. Am I going to develop those skills? Probably not. But I could.
I actually helped drive someone at my bike co-op to linux by comparing it to why I fix my bike. My bike is janky, but I’m the one who fucked it up. And no irritation is “get over it” it’s “here’s what it would take to fix it, decide if it’s worth it”
Man I really wonder what the venn diagram of Linux users/furries are. But I’m thinking it might be a circle within a circle kinda thing.
It’s just the same classic bleed over of socially awkward nerds being into multiple things, like Star Trek, Star Wars, tech, programming, RPG gaming, anime, comic books, and of course, the furry fandom.
You’ll find lots of Linux users among those subgroups too.
I’m a Linux user since 2010. I’ve been pure Linux since 2020. I do not fall under any of those groups tho :/
It’s not too late >:3
I’m in 5/8 of those, yikes.
Same!

So much does.
It is not two concentric circles, but the overlap is gigantic.
Both circles are entirely contained within a larger circle that says “neurodiverse people”, though.
At least I get to find out why the spyware doesn’t work… and fix it 💪.
On the other hand, I have a hard time explaining to my family why shit in my computer constantly doesn’t work… or I’m in the process of fixing it 😂.
If there are any car guys in the family, simply tell them it’s sorta like that. Tinkering is a totally valid hobby, but older people have an easier time understanding it with cars (because cars have been around longer, mostly :P)
Oh, they’ve kinda gotten used to it by now 😂. At least that’s what I think… they do avoid my computer though, so that’s a plus, I guess 😂.
I have no idea what I’m doing at any point in the process, and that’s why its fun.
Or you start fixing something, and you find 3 other problems, not related to the one you started fixing 😂. You just didn’t know about them cuz you usually don’t use libfoo for the thing you currently need 😂.
It’s like going to the doctor for a checkup and finding out you have diabetes 😂… I mean… it’s not good, but better now than later, right 🤷 😂.

That’s so stupid, why am I laughing
There was a rather well known Ubuntu meme logo going around in the mid-2000s that was just the regular logo but three different people’s butts touching in the center.
The ubuntu logo looks kinda like an abstract drawing of an anus–
Goatse vibes.
Where can I find this logo? asking for a friend
I’m in no way a Windows fan. Use manjaro for desktop, and ubuntu for servers as of now but keep trying new distros and love changing all the time, unfortunately. However, I dread to think if I was stuck on another planet with a linux distro without internet access to troubleshoot or find out how to do random things…
And what would you do on that other planet without Internet and stuck with Microsoft Windows and no way to activate your OEM license ? At least Linux has nice manual pages to read in the main time off-line 😄
Haha touché
Start downloading all source codes to prep for when that happens. That way, you at least have a way to find out.
I have an unactivated windows computer I’ve been using for 3 years, it works fine and even gets updates it just says “activate windows” in the corner of the screen.
It used to be it also wouldn’t let you change your wallpaper, but I don’t know if that’s still a thing and there were ways around it.
Probably true, but that particular computer just runs a Plex server and a few other things so the wallpaper doesn’t matter to me
I suspect that’s not a mission critical function for someone stuck on another planet with no internet.
Not unless the only way to get back home is to change the wallpaper!
I believe you can simply leave it unregistered and it’ll still work indefinitely. Plus you aren’t getting updates forced down your throat, since you’re not connected to the internet.
I know right? You might have to use the man pages.
I love it how you just want to do something simple and very, very common and normal with a command but you don’t know the magic flags to get it to do it and they’re not just a logical one (like, say “-a” for all) so you do a man for it and it has something like 50 flags listed in alphabethical rather than functional order, some of which only make sense in specific combinations (which are never show together and have to be found by reading the entries for all 50 flags) and there are no examples anywhere to be found of normal usage scenarios for that command.
So that’s when you use some internet search engine and it turns out the most common simplest use of it is something like “doshit --lol --nokidding --verbose=3”.
Drop manjaro l, start using endeavor, thank me later when your system doesnt randomly break on an update
honestly, as a long time arch user on my desktop, who has used both manjaro and endeavour, i don’t like either. Manjaro dev team isn’t great, but the biggest problem is holding back packages for 2 weeks or however long it is. The biggest problem i had with endeavour was that they keyring broke (not the archlinux one) and the only way to fix it was by installing an untrusted keyring forcibly… To be fair, it was a very old distro, but these are pretty funny issues to be having considering the arch keyring updated just fine.
Long-term Manjaro user, no issues.
Just don’t mess with AUR unless you have to; it’s a good practice to make snapshots as well.
Endeavor is no more stable, it’s very much unfiltered Arch with all its issues of “oh, you didn’t read an update note? Your bad”. Arch had literally broken GRUB on updates in the past.
Used Manjaro in the past, probably the worst distro i’ve tried. Multiple screens issues, kernel issues, keyboard and mouse issues, and when i look at the forum thoses are commons on Manjaro
Interesting. Never experienced any of that personally. Might depend on hardware?
Maybe, but it mean Manjaro has serious Hardware compatibility issues with most.
endeavour was one of the leading grub issue reporters iirc, because they actively update grub on manual updates. Unless you hook it on your arch machine manually, or do it regularly yourself, grub doesn’t update, and tbh there isn’t a huge reason to do so. If it works it’ll continue working.
The point is, updates break Arch (and as such Endeavour) just as they can break Manjaro; and, as a matter of fact, one of Manjaro’s selling points is exactly that they allow updates to be tested before putting them into stable repository, making the system more stable.
And, as with any distro, Manjaro doesn’t break if you don’t change anything.
Does it make Manjaro as rock solid as Debian? Hell no. But suggesting switching to more bleeding-edge Endeavour seems like something that certainly won’t help with stability.
The point is, updates break Arch (and as such Endeavour) just as they can break Manjaro; and, as a matter of fact, one of Manjaro’s selling points is exactly that they allow updates to be tested before putting them into stable repository, making the system more stable.
until you install an AUR package, and realize that having 2 week old main line repos is not going to help you at all. Or that archlinux is based on bleeding edge security, move too fast for anything to be implemented, and if something is, then it’s going to be removed very quickly, that kind of stuff now requires manual intervention on manjaro.
Archlinux literally has a new board for every update cycle they roll out, anything significant that you should know about is going to be in there. Otherwise, it’s probably going to be fine.
Realistically, i think things like manjaro and endeavour are going to be a worse experience than something like arch long term, but that’s mostly just me not liking derivative distros. Short term, i think they’re fine. I just don’t understand why things like endeavour feel the need to complicate the existing repo structure.
I absolutely don’t understand why Endeavour exists and is so popular.
On Manjaro side, the criticism of AUR compatibility is valid, and that’s why even Manjaro devs warn against actively using it; although, I have to mention, I personally have never encountered issues related to this 2 week delay, even when at first I used and abused AUR with no respect to warnings. (then decided to be on the safe side just in case)
Also, repos include everything except edge cases, and for those, Flatpaks cover most of it. Currently, I have 2 AUR packages installed, one of them being an obscure printer driver, and other being OcenAudio, a sound recording tool I prefer.
To me, Manjaro has shown itself as a safe, predictable, noob-friendly system that doesn’t lead you the ways of Arch unless you choose to go there, while benefitting from the rolling release model and wonderful optimization.
Endeavour, on the other hand…seriously, it’s a little more than Arch skin. Even Garuda makes much more sense.
honestly, i think an arch distro that is basically a preconfigured version of arch built for the end user a good thing. Takes away the pain of setting it up, but keeps the benefits of running arch.
Linux might not do everything you want it to, at least not easily, but it usually doesn’t do things you didn’t ask for, unlike all proprietary OSs these days.
I’ll remember that the next time someone makes a post like “why did apt upgrade install the snap version of Firefox”.
Usually. You already know the answer to that…
Canonical is like the Microsoft of the Linux world
Lol, I relate with this a lot.
I always figure it out, but Linux is not user friendly. The last issue I had was trying to get my vpn to work. It took me a few minutes to realize my vpn provider doesn’t support a gui on there.
This is the issue with Linux. It needs better support and adaptation. If it got that focus from third parties, I’d gladly make it my daily driver.
Here’s to hoping the attempts from companies like steam are only the beginning of a new thriving trend!
On my end, like –
I have about as many tech issues with Windows as with Linux – It comes with me enjoying tinkering as a hobby I think?
BUT, and this is important, when shit breaks on Linux, there is always output on the terminal, or a log file, or something else you can check, and even when I don’t know what to do about it, a simple copypaste of the error on internet search usually gets me some answers.
When shit breaks on Windows? HOLY FUCKING SHIT. It just sorta dies and leaves you in the dark with nothing to go on for troubleshooting. Windows wants to make computers into magic boxes that “just werk”, but it never really gets there, and instead what you get is something that breaks just as often, but is a lot more opaque.
That BSOD with an emoticon lives rent-free in my head. Like who the fuck thought it was a good idea?
Also, even when you actually get an error message (which you probably had to dig through the awful mess that is the event viewer… Seriously, the only update they’ve made to it in the last twenty years was to split a bunch of things into a ton of individual logs that are more than painful to dig through), it’s cryptic (if it tells you anything at all) and pasting it into search gives you nothing relevant, and quoting it gives you nothing at all (even the part that’s obviously the generic part of the error), or if it does, it’s a couple hits with people asking for help and either getting no replies, unhelpful replies that misunderstand the issue, or tells them they’re asking in the wrong Microsoft support forum
Like… Come on, Microsoft. You clearly coded this error in the operating system. Put at least one page in documents online with at least something useful about it…
The few times I had to use the Windows Event Viewer I left having learned - Uh - Nothing except a newfound hatred for Microsoft. It’s weird to navigate, and the logs are close to useless.
Application terminated due to internal error
This is the issue with Linux. It needs better support and adaptation.
I point you towards Fedora. Its indirectly backed by IBM.
From the article…
Although Fedora isn’t the most popular Linux OS, it’s certainly one of the most well supported
For me, being backed by IBM isn’t exactly a selling point… Not as bad as backed by Oracle, mind you

Granted, corporate shenanigans are never fun to deal with. But say what you may, they know how to support what they sell, hardware and software.
I don’t feel very supported by their killing off CentOS and cutting promised support down from many years to the end of the year rather suddenly… Forgive me if I don’t trust them with much of anything after that
I don’t feel very supported by their killing off CentOS and cutting promised support down from many years to the end of the year rather suddenly… Forgive me if I don’t trust them with much of anything after that
Fair enough. But you’re speaking about policy and politics, I’m speaking about day-to-day hardware and software support/compatibility and how well it works with a wide range of hardware. I’m speaking about the OS itself; it just works with for me, without any hassles.
They literally cut promised support pulling the rug out from under many people and businesses that put their trust in that support. Not sure how that doesn’t count as “day to day software support”. Being able to trust that their word will be honored and I’ll not be forced to scramble to replace their os is kind of important and losing that trust understandably costs that trust pretty much across the board, at least for me
The terminal is not an accessory like on Windows, it’s apart of the daily Linux experience
It shouldn’t be though. A command line interface is not user friendly for entry-level users, and until Linux UX designers realise this, Linux will never gain a greater market share. And we have seen this with Ubuntu, Mint, and other “user friendly” distros gaining popularity. I’m not saying that we should necessarily aim for broad-scale adoption of Linux as an end in itself, but more users means more support for Linux which means a better experience for all.
Linux was never meant to be “user-friendly”, Windows and Linux are 2 differents things, but i know this fact is hard to accept tho.
its only user unfriendly if youre used to having a gui for everything like windows and mac users in all reallity the real issue comes from children not being taught how to use computers growing up and instead relying on shitty non foss bloatware like windows
So user unfriendly for literally every regular user.
That is the definition of not being user friendly.
nah only for ones with incompetent parents
But that is the reality of most users today. They expect to have a GUI because it gives them the options right there, rather than having to go and learn what commands this particular system accepts. If you don’t cater to those users, like my parents, my friends, my grandparents, my teachers, and basically everyone I know who isn’t a computer nerd, and then expect them to “come to their senses” you will be very disappointed. Good design meets users where they’re at, it doesn’t expect them to “educate themselves.”
right but thats not an os issue thats a societal issue you wouldnt expect someone using a car not to understand how to swap oil or replace windshield fluid right?
If Linux wants to ever have adoption outside tech people then it can’t be. If a normide has to open up a terminal then that’s already one less Linux user.
I have used Linux for my main PC for a very long time but I have also worked in tech support and your average user will never ever use an OS where using the terminal is mandatory.
I my opinion there should be some hobbyist distros where the terminal is your daily experience like Arch or Gentoo but the main focus should be accessibility for the average user if adoptability is a goal.
If you don’t like using the Terminal use Mint, but even this one require some basics terminal skills that everybody could learn fast. Linux is made this way.
Oh, there are tons of distros where you don’t need to use the terminal for anything, even Manjaro, an arch based distro, doesn’t need you to ever open the terminal. I was just saying that if adoption is the goal then using the terminal can’t be a requirement for a normal user experience.
Wrong example, Manjaro is probably the less stables distro i’ve tried, and thoses issues seems to be common when you look at the forum
What I mean is that using the terminal isn’t mandatory in Manjaro while Arch and Arch based distros all require it. So for that it’s an excellent example.
As for stability it’s a bit more stable than Arch itself from my experience but I still has issues. The most stable distro I have used was Pop OS, I didn’t have a single issue there for like 3 years straight, I only switched because of a hardware change and Pop OS’s Mesa version was unstable on the new hardware.
My central point is still that you will never in a million years get the average computer user to use a terminal.
you will never in a million years get the average computer user to use a terminal.
We used to back in the 20th century, when computer didn’t had GUI
If more casual PC users got on to it, i wouldn’t call it a daily experience. Yeah you need to use it some times but once everyone is set, you dont really need to mess with it
I switched to Mint a few months ago and to be fair I have only messed with it a couple of times mainly just after the initial installation

UNBUTT ON
Me this past weekend trying to setup GPU passthrough to a VM. Bought an AMD card just to passthrough my existing Nvidia one and have had nothing but issues with multiple distros 😔
oh yeah gpu passthrough is very shitty with nvidia cards (typical), try passing your amd card through instead
That might be a questionable choice given that this would leave the nvidia driver running on host machine and it’s usually the most fucky part of this whole operation.
Any specific issues? Pretty sure there’s lots of people in this sub who could help you out with that, myself included.
Passthrough not actually working, VM not detecting the GPU or not loading qemu properly even with everything loaded properly. Tried on 3 different distros (Ubuntu and arch based) and none worked. Might try the other suggestion to swap the cards. Just means I’ll have to redo my water loop for the 2nd time this week 🙃
This is, indeed, uncommon. Typically the GPU either gets detected(abeit, often with errors), or the VM doesn’t start at all. Do you use libvirt by and chance?
Yes, I installed libvirt along with the many other packages required
But are you launching VM via virsh/virt-manager or directly using
qemu-system-x86_64? Could you provide the XML or the command line you’re using? What doeslspci -ksay in regards to your GPU’s?Sorry for the delayed reply, don’t have much free time on work days.
Was launching the VM via virt-manager. Do you want the overview XML or for a specific category within virt-manager?
lspci -kshows both my GPUs are there now but trying to load the BM says iommu group is not viableDo you want the overview XML or for a specific category within virt-manager?
A full XML, unless you have something private in there, which you can remove. I just remember that for nvidia’s there could be parts preventing load anywhere. In my case, for example, it was booting a BIOS VM instead of UEFI one.
shows both my GPUs are there now
But what’s the driver used? Should be something like this (my laptop for example, without irrelevant lines)
01:00.0 VGA compatible controller: NVIDIA Corporation GA104 [Geforce RTX 3070 Ti Laptop GPU] (rev a1) Kernel driver in use: vfio-pci 01:00.1 Audio device: NVIDIA Corporation GA104 High Definition Audio Controller (rev a1) Kernel driver in use: vfio-pci 06:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Rembrandt (rev c7) Kernel driver in use: amdgpu 06:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Device 1640 Kernel driver in use: snd_hda_intelthe BM says iommu group is not viable
Well that’s something. Check the script at arch wiki on VFIO, at the paragraph “2.2 Ensuring that the groups are valid”. It should print out the IOMMU groups you have in your system.
Basically, a thing with IOMMU is that you must pass all or none of the devices down to VM within each IOMMU group, even if you don’t necessarily want them in your VM. In most cases, that means also passing the built-in sound card that feeds audio via HDMI outputs (the .1’s in the above example). In cases where there’s something else crucial in that IOMMU group, there’s ACS patch but that’s a hack and should only be used as a last resort.
Good to know, I was just thinking of doing this exact thing. I haven’t pulled the trigger on the AMD card though. I wanted it for wayland, but I still want to do CUDA things with my Nvidia card.
Dual GPU build?
I like Linux because it let’s me do whatever I want on it. Windows is so controlling. For example in Windows, there are lots of occasions where a window will pop up asking you do make a decision, and while that window is up, you cannot click on any of the other windows. Say I want to save a file, but I want to look at the document. If the save window is up, I can’t review the document because it wont let me. That’s so freaking annoying.
Aside from all sorts of little annoyances like that, Linux is sooooo customizable. Using KDE PLasma, I could just add widgets on my desktop that show me the status orf my computer or even let me write notes right on the desktop. To do that on Windows, I have to mess with Rainmeter for days trying to figure out the proper settings using a text protocol I am not familiar with. While Linux does run into some difficulties, they tend to be easily solvable by just running an Internet search or posting on a forum relevant to your distro/DE.
Lastly, there are lots of things that just work on Linux that don’t on Windows. For instance, my network printer just works. I didn’t even have to install a driver. I just added the printer and it did everything else for me. Or, I could use KDE Connect and easily transfer files from my phone to my desktop and vice verse, get phone notifications on my desktop, and even text from it without any tinkering. It just works.
The only reason I could see people using Windows aside from subjective preferences is when they’re forced to because of work or they realllly want to play a one fo the few games that doesn’t work on Linux. Otherwise, Linux is just objectively better as a whole.

I hear you. Another thing I like about Linux is the virtual consoles. When the GUI would show the same thing you just described, and imagine you’d have some 50 program windows open, you can just switch with control alt F1 to a virtual console, log in and shut down a certain program or do some manual page reading. And after that simply switch back to the GUI.
It’s generally a lot more control-able with a terminal. I can remote into any of my machines, including IOT stuff, and have full control over any of their settings, like, say, volume or display brightness or whatever. With GUI it’s like what, RDP/VNC/Teamviewer in? Gonna be painful over mobile connection… Apps? The developer just went bankrupt and now it’s dead because the cloud server is down. And I haven’t even started on automation…
Also, changing multiple behaviours in one place is also nice. Say, I want to remove the volume osd and control how I want to manipulate windows. It’s either an array of small disconnected utilities(in this case, HideVolumeOSD + AltDrag), or huge RAM hogger utilities like DesktopFusion, or, I can just edit it in my WM config with just a couple of lines. Things like adjusting volume based on window position (to have a background and foreground media displays) is completely out of the picture on Windows and are a breeze on Linux.
In short, lots of benefits. The downside, I guess, is a complete disarray of components. Like in case of volume again, I have pipewire daemon pretending to be pulseaudio which is middleware for alsa… and all of their corresponding utilities work but control the same thing, so it’s incredibly confusing which ones to use. Also webapps for some reason can control their own volume in the system mixer(?) So there’s at least 4 ways to adjust just one slider. And it can create confusion when multiple things interact with different interfaces - I’m still to figure out which fucking thing keeps setting the
grp:alt_shift_toggleoption in my keyboard layout.In short, lots of benefits.
Agreed :)
The downside, I guess, is a complete disarray of components. Like in case of volume again, I have pipewire daemon pretending to be pulseaudio which is middleware for alsa…
Right. I guess this has to do with the history of audio support in Linux. From OSS to Alsa to Pulseaudio to Pipewire, and some sort of compatibility and upgrade safety for the Linux distributions maybe. Lately it took me a lot of time to solve some sudden audio problems with mpd server software. Then I tried Mopidy which works with GStreamer, completely different, and with different results. In the end I solved the problems with mpd, which was good because mpd can play audio from mp4 video, and I am not sure this can be done with Mopidy. Saves me a lot of video or audio formats converting.
The problem with that meme comic is that it doesn’t state which distro the fox was using, as far as the level of supported it requires.
Everyone who uses Linux knows that there are some distros that require more ‘tender loving care’ by their users than others.
“unbutt” and something below it, with the circle logo, it’s unbuntu.
It’s probably a broken snap package or something.
Not even, man. I accidentally ran
sudo apt remove python3instead ofsudo apt remove python3-piplast week.I just copied my files to a flash drive and reinstalled Ubuntu lol
whoops. Usually that stuff can be fixed with a reinstall. Normally uninstalls don’t yeet all config for that kind of thing, unless you tell it to.
It uninstalled a bunch of dependent packages too, including my graphics driver :(
ah yes, a classic, uninstalling python and taking your GUI with it also.
sudo apt install python3 didnt do it?
It uninstalled a bunch of dependent packages too, including my graphics driver. I probably could have looked through the apt history and rolled them all back, but I don’t remember how to do that off the top of my head, and reinstalling took about 20 minutes.
Surely it asked you to confirm before it remove it and all that uses it. It was just doing as you told it to do and will have asked you to confirm. You can’t blame it!
We can call it not user friendly though
How many times should it ask you if your sure? If it was serious, as in, it could actually break stuff, it gets you to type “do as I say” or something.
“unbutt” and something below it, with the circle logo, it’s unbuntu.
Fair enough, but I was speaking more to the meta of the subject (not all distros are created equally), but still, you’re right.
but at the end it is possible to solve any and all problems linux, and troubleshooting difficult cryptic errors successfully makes you feel like a very smart god
Until you forget what you’ve done and face the same issue again.
Eh, not a god. But the solution is somewhere there…
Omnipotent, just not omniscient.
yea lol
Sometimes it takes way too long though. I had a display issue that made many of my tiny Linux boxes stop working and it took me almost a month to figure out the issue. I had to revert to an older kernal to fix them all. They just randomly stopped working one day lol. Makes me not want to accept updates so that’s not great
always take a backup with timeahift before updating
For a given definition of ‘any’. For a while, the solution to my problem would have been to contribute code to PulseAudio and/or ALSA, which was (and still is) beyond what I could reasonably do.
fair
I’m no artist, but couldn’t Xenia have a white outline around her black arms/hands so they can be seen better against dark backgrounds?
As an Amateur Artist (my pfp was drawn by me) – You are correct. Though in this particular picture I have no trouble telling her shape from the background objects.
Addendum: In cartoon art, generally, black fills are avoided. Instead you use very dark grey for black things, so as to keep the (black) outline distinct. Other artstyles have other ways of doing stuff.
Me after I spent a whole evening being unable to boot into grub after trying to get Wayland to work. Wayland will have to wait for a bit longer…
NVidia?
Yuppers. I need CUDA for my machine learning projects, both for hobby and professionally. I considered AMD and their alternative at the time, but it wasn’t supported on their consumer cards back then, and I also didn’t fully trust their commitment. It’s getting better though, so hopefully AMD can convince me for my next GPU in a few years.
Proprietary NVidia API for paralell computation.
Very useful for Machine Learning stuff. And for Crypto though that has fallen out of fashion nowadays.
Basically if you’re doing a fuck-ton of math and want it to happen very fast, you want to use a GPU to do it (GPUs are literally made for that – That this helps them draw video games is a happy consequence), and NVidia’s CUDA tech makes it… Easier? Faster? Not sure what the proper difference is, but yeah.
Disclaimer: I only think this is true, correct me if I’m wrong.
GPUs do floating-point math, in their own precision. They have way more computing cores than usual CPUs do, because they do only FP, so are smaller. Also they have their own memory on the board, which has faster access timing than RAM.
Usually we put multiple matrices (multi-dimensional array of numbers) inside, and expect some back, while the entire load of math is done on the GPU. Now it can do milions of computations very fast, in parallel, never care about anything external like RAM or goodness forbid disk or network (which is monumentally slower).
Now CUDA is the ‘platform’, that lets you write the code for general programming and to utilize not only the computing cores on the GPU, but also move data between the GPU, CPU and RAM.
This is a weak example, but back in the day, I mined BTC on my PC. IIRC, it just runs md5 hashes until it finds specific output. MD5 is just a mathematical algorithm, and you can run it on both CPU and GPU.
My CPU at the time (I think it was 6 core Phenom II?) could output 12 milion of md5 hashes per second. My GPU - AMD Radeon 6990 - after some tweaks and full table fan blowing from the side inside chasis could get close over 800 Mhash/s.
So there are direct incentives to use GPU for other cases than gaming, specifically machine learning is all about floating point math. But to do that, you want to be able to write your own software that implements the algorithms to squeeze every last bit of performance out of it, and that’s what CUDA lets you do.
CUDA is specific to nVidia GPUs, AMD is trying to catch up with ROCm, but came almost a decade later, so they have a lot of catching up to do. Intel also started their own oneAPI, and both oneAPI and ROCm are open-source, with CUDA being closed source, so only nVidia can modify it.
Honestly, if it wasn’t for NVIDIA’s BDSM chokehold on machine learning, they would be pretty done for
Their GPUs have brute force, and are always top recommendations for gaming PCs. I buy all red, but feel like nVidia is still more popular among the gaming community, excluding Linux.
Secureboot?
