What do you mean with film emulation that Kdenlive can’t do?

Nibodhika ,

I don’t use Logseq, I use Silverbullet, and yes, it helps A LOT. I have lots of random notes on random pages on how to do things at work, or on my personal servers or whatever. You know that feeling of “I’ve already had to deal with this, how the hell did I do it?” It’s completely gone.

If you use a good organization system with a hierarchy that makes sense and tags you can easily find stuff, so you can turn off your brain from having to remember all of that and it can focus on the thing you need to actually solve now. Don’t know if you’re old enough to remember a time before cellphones, we had to remember our friends number, nowadays this is not a concern, because your phone will remember the number for you, it’s like that but for everything, very liberating.

Nibodhika ,

I think I didn’t expressed myself correctly, what do you mean with film emulation?

Nibodhika ,

Your disk is like a file cabinet, there’s also an index folder where for example it says that “your file.txt” is in cabinet C7. You go there and there’s a sheet of paper written in pencil with the contents of your file. In this analogy here’s how several solutions work:

  • Delete the file: throw away the index folder. Now if you need to write to disk you might think C7 is free and when you go there to write something else you find the old paper, which you erase and write on top. But if someone gets to your cabinet before that and they open C7 your file Will be there in its entirety, there just isn’t an index telling you which cabinet to open.
  • Zero wipe: you go to C7, erase the file, and then throw away the index. Now if someone gets to your cabinet they might go to C7 but all they see is a white sheet of paper. However it’s technically possible with a white sheet of paper to see what was written before, so this is considered better but not perfect.
  • Random wipe: same as before, except you erase and write random stuff on the sheet of paper. So it becomes a lot more difficult to recover what was there.
  • Multiple passes: Same as before, but you do this several times, so after dozens of random writes your original data should be completely impossible to recover.

I really miss Emily, hope she comes back soon, but I understand her wanting to be on her own for a while, but honestly her videos were the best ones always.

My friend didn't have a great experience with Linux

I have been daily driving Linux for over two years now and I have switched distros many times. So, when my friend bought a new laptop, I convinced him to install Linux Mint on it. I asked him if he wanted to dual boot, he said no because it would fill up all his storage. We installed Linux Mint. The other day, he wanted to play...

Nibodhika ,

First of all you should have asked what he wanted to do with the laptop, the moment he replied playing games that are not on Steam you should have let him use Windows. Secondly, a laptop with 256GB of disk is likely going to have very low amounts of RAM and an onboard GPU, performance is going to be shit on Windows as well, you should have let him use that before, I think it’s highly likely that Windows itself would run like shit on it, so after a year or two putting Linux on that laptop would have blown his socks off. But the problem is that he didn’t get to experience any of that before you touched the computer, now he will claim it’s your fault that games don’t run or Windows is slow. I’ve been there, a friend had issues with the laptop, I said I didn’t understand Windows and would only help if I could put Linux, at first everything worked great, but then the friend needed special software that wasn’t available so I had to reinstall Windows for them (and btw, you OBVIOUSLY should reinstall Windows for your friend), and then everything on that laptop was my fault, even the problems the person was having before were somewhat my fault because I had put Linux there.

Nibodhika ,

The only games I have installed outside of Steam are emulators. Even if the majority of people here tell you they have games outside of Steam, this is likely a skewed statistics because people who tinker with their deck are more likely to join a community about it. I would guess that 70/90% of people with decks have never even opened desktop mode.

To me $100 doesn’t seem that steep, if you’re making a $5 profit with your game you only need to sell 20 extra copies for it to pay itself. If your game is specifically done for the Deck your audience is by definition on the Steam store, only a few are also outside of it.

I’m someone who uses Linux daily, I like tweaking with my deck, but realistically I never even considered installing games outside of Steam because every game I want to play is on Steam, and I imagine that several other people who tweak with their Deck are also in the same boat.

Nibodhika ,

Yeah, in that case it makes sense not to put it on Steam.

Although in your shoes I would put it on Steam for something like $5 and free on itch. Afaik Steam doesn’t mind this as long as you don’t offer a steam key for free on itch, but if you charge the same value as on Steam you can offer a key there as well, so you could do free version on itch but a minimum of $5 to get a steam key, and sell it on steam for $5. Whatever you can sell on steam is likely to surpass the $100 margin. But I can see that as a hobbyist you might not care to setup accounts for payments etc, just want to get your game out there.

In any case I’m interested in what a game specifically designed for the Deck would look like, so please post a link when you have published it.

Nibodhika ,

Well, I also use a rolling release distro, my disk died last week so I had to reinstall, so technically FULL hardware update might require a reinstall (safer than copying the root folder from one disk to another since the old one was bad), but yeah, before that I’ve replaced almost every piece of that laptop without a reinstall, even switched from Nvidia to AMD.

Nibodhika ,

Brainfart, I said laptop meant desktop, obviously didn’t change the GPU on a laptop.

Nibodhika ,

Deck uses AMD

Nibodhika ,

An Nvidia 3070 costs 420 and benchmarks at 22,403 (benchmark point per dollar 53.34) An AMD 6800 costs 360 and benchmarks at 22,309 (benchmark point per dollar 61.97)

So you get a 0.4% drop in performance for a 14.3% drop in price. That is significantly more performance per dollar.

Or if you go with a 3070ti ($500 23,661 -> 47.32) vs a 7800 XT ($500 23,998 -> 47.97) you get a 1.4% performance increase for free (not really that significant I know, but still it’s free performance)

All of the numbers were taken from www.videocardbenchmark.net/high_end_gpus.html

Nibodhika ,

AMD no doubt. Back in 2017 AMD had recently open sourced their drivers I was in the market for a GPU, but you know the saying “fool me once shame on you”, AMD used to SUCK on Linux, people always seem to forget about it, so I chose an Nvidia. I don’t regret my choice, but over the years AMD proved that it had really changed, so my new GPU now is an AMD, and the experience is just so much better.

Today it might be a turning point, maybe Nvidia will change, maybe they’ll change their mind and fuck It up, they’ve done it in the past, so I wouldn’t buy an Nvidia just in case they do the right thing for once, AMD is already doing the right thing for years. Also if you go with Nvidia forget about Wayland, and every day more and more distros are going Wayland only, so if you go Nvidia you might find yourself holding a very expensive paperweight in a few years.

Nibodhika ,

If you need to ask for a distro the answer is Mint, if you didn’t need to ask the answer might be different, but then you wouldn’t be asking.

Nibodhika ,

No you don’t, they’re mutually exclusive, there are a couple of ways to check which one you’re running, from lsmod to check which module is loaded on the kernel to my favorite: glxinfo | grep -i vendor

First of all don’t run random commands from the internet without understanding them. Now to what that command does, glxinfo prints a lot of output about what’s being used to render OpenGL, you might need to install mesa-demos, mesa-tools or something else if glxinfo is not installed by default. Then the pipe, i.e. the vertical bar | says to grab the output from the left command and feed it to the right command. grep is used to filter an input, and the -i flag tells it to do it without being case sensitive, i.e. Insensitive. Then vendor is the text you’re using as a filter. Long story short that command shows information about the vendor used to render OpenGL.

If it says Nvidia you’re using the proprietary driver (which you should use from your other comment). If it says Mesa you’re using the open source drivers (which should be “fine” but will have very bad gaming performance)

Nibodhika ,

I think a better analogy is “remember when you had an iso that you had to burn onto a DVD to be able to boot from it? Or to be able to have the CD player recognize it instead of just writing the songs into it?, sort of the same thing”.

What you downloaded is a binary image, i.e. the sequence of 0 and 1 needed for a computer to boot into Linux, now you need to feed that sequence directly to the computer, but the computer only knows how to read it from a thumb drive directly, not from a file inside the thumb drive, so you need to write that sequence bit by bit in order on the thumb drive. Back in the day we used Nero for dvds, Rufus does the same but to a thumb drive.

Fun fact in Linux you can use dd which unlike what most people say doesn’t stand for Disk Destroyer (although certainly lots of disks were destroyed by it), which is an application that does binary writes. Hell, in Linux you can actually do cat image.iso > /dev/sdb and that should work, that is essentially print the output of the file image.iso and write it into /dev/sdb which should be the second disk plugged to your system (first one being /dev/sda).

Cool, I started using Linux back in 04, but I think not that much changed, I think it’s mostly people who change the way they look at Linux, outside of gaming, for day to day use, Linux was very usable even back then.

Nibodhika ,

Ok, prime laptop, run the following then: prime-run glxinfo | grep -i vendor if prime-run doesn’t work there are others like optimun, I’ll check which one is the correct for mint and reply back.

Nibodhika ,

From our other reply you should be fine, this is a prime laptop so it will use the CPU for everything unless you specify different z that’s by intent to preserve power since Nvidia cards consume lots of it and otherwise your battery would last an hour or so, windows does the same, the difference is that Windows tries to guess which apps need it and on Linux you have to be specific about it.

Nibodhika ,

Yeah, there might be an nvidia-prime package or something, either that or the command in mint must be different. Quick Google didn’t helped me and it’s after 1AM for me so my brain is not helping either, hopefully someone else can help you, if not tomorrow I’ll be back.

But everything looks correct, Nvidia settings only works if the Nvidia driver is installed, now all you need is to figure out how to tell Mint to run things with the Nvidia GPU and you should be good to go.

Nibodhika ,

Quick test you can run to confirm this is lspci | grep nvidia and lspci | grep nouveau one of them will display something and the other nothing (hopefully), nvidia is the name of the properietary driver, nouveau is the open source one.

Nibodhika ,

Hey, others have already replied to a lot of things and you’ve already downloaded Mint (which is what I would have recommended also), so I would like to point out some things I always tell newcomers and some specific things for what you said.

First of all: Linux is not Windows is the hardest lesson to learn, there are a lot of things you’re used to doing one way, but that doesn’t make that way correct. The main example is installing software, looking on the internet and downloading a binary from a website is NOT how you do it, the example I always give is that of a smartphone, it’s just as ridiculous to do in Linux than on a smartphone and for the same reasons. Instead use the package manager of your distro, that should work like the play/app store (except it’s free), and if something is not there maybe you can add a repository to it, or maybe the program doesn’t exist on Linux, only as a last resource should you do it manually.

Partitions and drives: Linux doesn’t have the concept of a C: or D: drives, instead drives/partitions are mounted onto regular folders, so navigating through them is seamless. This means that if for example you were t mount the folder that contains all of your personal user data (/home) into a different partition from the root of the system (i.e /), you could format and change the system entirely without losing any personal data. This is very useful because it’s very likely you will poke something and break stuff, with much freedom comes much power to break things, so being able to reinstall your system without worrying about your personal data is a good thing.

Drivers: mostly you shouldn’t worry about drivers on Linux, unless your GPU is Nvidia, if so you should worry about drivers a lot. Nvidia’s work best with the proprietary nvidia driver (instead of the default open nouveau driver), but the fact that the driver is proprietary makes it a pain in the ass to deal. You should 100% use it since you’re gaming, but you should steer away from distributions that use Wayland (nevermind what this is for now) instead of X11 (Mint so far uses X11). If you have a Radeon you shouldn’t worry about this.

I use my PC mainly for streaming

Be careful, afaik not all streaming software/sites are compatible with Linux. But that’s not a world I dabbled much, I know OBS works excellently, but other than that don’t know much.

downloading torrent files who’s copyright you don’t need to worry about

We all have torrent downloaders, for our Linux iso which are distributed via torrent of course

and light gaming. Usually just messing with New Vegas mods.

Iirc new Vegas is not on the supported list on steam, so you need to go to settings and enable Proton compatibility for all titles. I’ve never put mods so not sure how to do that, but you might need to read something before because the game is being run through a compatibility layer, so the files are not exactly where you would expect, and if you need to run a binary to find those files it needs to be in the same profile as new Vegas (each game creates their own profile based on steam ID, and each profile is in a different folder). Other than that New Vegas works perfectly on Linux, I’ve played it a long time ago, and now with the TV show I’ve started again.

Last but not least: Welcome!

Nibodhika ,

There are games that don’t work with Proton, but at this stage is 99% games that are actively trying not to work with Proton, e.g. DRM infested games.

Nibodhika ,

Yes, first quoting Sir Terry Pratchett:

J.R.R. Tolkien has become a sort of mountain, appearing in all subsequent fantasy in the way that Mt. Fuji appears so often in Japanese prints. Sometimes it’s big and up close. Sometimes it’s a shape on the horizon. Sometimes it’s not there at all, which means that the artist either has made a deliberate decision against the mountain, which is interesting in itself, or is in fact standing on Mt. Fuji.

As such let’s look at the Granddaddy of all modern Medieval Fantasy, in Tolkien’s work there are several human/elf couples of renown, from Beren and Luthien which are not in the movies so people don’t usually know to Aaragorn and Arwen (who are a central point of the movies). Not only that, but we know that they can produce offspring, because Elrond is a half-elf, not only is he a half-elf, but both his parents were half-elves.

In short, yes, they do.

Nibodhika ,

Yes, but that’s boring, they even mentioned it in the article right before they talk about the Ethernet port, here’s the link if you want to do it yourself github.com/TheOfficialFloW/PPPwn

Nibodhika ,

Yes, because machine code for the legacy machine is how the game was made, you can’t be 100% sure that recompiling it for other platforms won’t introduce bugs because of the difference in platforms. For example, the original Space Invaders used the CPU to it’s maximum to render all of the invaders, they weren’t normalizing by the dt between one frame and the next like we do today for most games, so this results in the game running as fast as possible, which in turns translates to the less enemies on screen, the faster they move. If you recompile that binary for a modern system it’s game over in less than 1 second, because current hardware can handle all of those spaceships as if it were nothing.

Nibodhika ,

I’m not the person who wrote the original comment, but again go back to my example of Space Invaders, if it had been archived that way it would now be essentially lost, because running a copy that was archived that way would cause the issue I described on my other comment. So I don’t understand your point, this is objectively worse in terms of preserving games, it might cause unwanted behavior that you’re not predicting, an emulator is not perfect, but can compensate for these things by emulating the hardware.

Nibodhika ,

First of all this is a chain of replies to someone who said that this would be the way to maintain games for the future. So that’s the argument that’s being attacked here.

Secondly with an emulator you can emulate hardware, so recompiling space invaders would cause the issue I mentioned and you wouldn’t be able to fix it because it’s a “bug” in the original code (not really a bug, but rather using hardware limitation as a feature), and my point is that you don’t know what sort of similar issues you might find here, therefore this is the worst format for preserving old media, ROMs and emulators are better for preserving (which again is the discussion here)

Decision of Next Os

I was Nobara user, then I am using Fedora right now. I want to use things like Hyprland etc. and ya know, Its damn cool to say I am using arch btw. So I’ve decided to use Arch Linux. But everyone says its always breaking and gives problems. That’s because of users, not OS… right? I love to deal with problems but I don’t...

Nibodhika ,

Arch doesn’t break on its own, but Arch is Arch, which means you might get an update where a post on the news says “btw, if you have changes to X file, your system won’t boot” or something. People don’t read the news before installing updates, but that’s also fine because I also don’t read them and have been using Arch for over a decade, and my system never broke on its own (to be entirely fair, one time back in 2007 I think, my system stopped showing jpg wallpapers because one library hadn’t been updated, the fix was to update my system the next day).

Also Arch is not hard to install, it’s labor intensive, but anyone with minimal Linux knowledge should be able to do it (and probably ask themselves why they’re being forced to do that).

Finally, Arch is not “cool”, lots of cringe people have ruined it and sometimes saying you use Arch sounds similar to saying you run Kali depending on the context.

Long story short, if you’re happy with what you have keep using it, I’m fairly confident you can get hyprland and everything else working on whatever distro you’re currently using. But if you’re determined to use Arch you should be fine too.

Nibodhika ,

Congratulations you essentially described what Stellaris devs did.

Little help here linux guys? Trying to figure out what distro to use

Yeah. It’s another one of these. But! Here me out! So I have some experience using Linux.

Was able to completely get off...

Nibodhika ,

Don’t use Wayland. I’ve had a very awful experience with Wayland and external monitors on an Nvidia with the proprietary driver. Because Wayland is the default in most modern distros it might be that all of the ones you tried used it. Try Linux Mint Cinnamon edition, it’s using X11 as the default and it’s Ubuntu based so it should be familiar grounds.

My grandpa used to do this way before smartphones, I remember his 30.000 days birthday when I was a kid.

Nibodhika ,

Not the user you’ve asked but I’m using Silverbullet and have been loving it, it ticks every box of what I was looking for:

  • Self hosted
  • Stores files in plain markdown text format
  • You can edit those files externally and Silverbullet picks up the changes
  • Allows customization and expansion easily
  • Provides queries that allow you to extend markdown to pull data from other files
  • These use an SQLite db to get these things to work fast, but if you delete them they get regenerated
  • Can be easily synchronized with multiple nodes by using synching to sync the markdown files

Will I ever be seen as truly British?

My family immigrated to the UK from Poland when I was six. I’m 20 now, speak much better English than Polish and feel like this is my land/culture. However I have a Polish first and last name, Polish passport and “unique” accent everyone picks up on, so despite this I’m usually perceived as an outsider. It makes me...

Nibodhika ,

It’s curious, I have a similar story but with different countries, and the reactions are VERY different. I was born in Argentina, but my family emigrated to Brazil when I was 13 years old. I speak fluent Portuguese but obviously have an accent that people can’t quite place, but once it’s pointed out they notice it. Yet the vast majority of my interactions about it are something similar to:

  • Where are you from?
  • I was born in Argentina, but lived in Brazil over 16 years
  • Ah, so you’re mostly Brazilian then

And I think that that says a lot about Brazilians and how they’re very welcoming and friendly. Unfortunately the British don’t seem to be the same way, at least from your experience, maybe people in larger cities are more used to immigrants so they would see you as mostly British or something.

As for the voting, for me at least the only way was to become a citizen, most countries allow you to ask for citizenship if you’ve been living legally long enough so you probably qualify. Just bear in mind that some countries ask you to abandon your other citizenships when you do so, so not sure if that’s your case and if it’s worth it just to be able to vote.

Nibodhika ,

I would argue the low cost option is already serviced by the Steam deck.

I don't know anything about Linux and the idea of installing it frightens me. Where do I start?

I bought a laptop yesterday, it came pre-installed with Windows 11. I hate win 11 so I switched it down to Windows 10, but then started considering using Linux for total control over the laptop, but here’s the thing: I keep seeing memes about how complicated or fucky wucky Linux is to install and run. I love the idea of open...

Nibodhika ,

I will keep this as easy as possible, but if you installed Windows 10 that’s much harder than installing most Linux distros. If you want a lengthier tutorial but with pictures go to …readthedocs.io/…/index.html

  1. Go to linuxmint.com/edition.php?id=311 click any of the links there, the nearest to you they are the faster they will be.
  2. Find a USB drive you can use (probably like you did with Windows, and just like then everything inside it will be lost, so make a backup on another drive) and plug it on the PC.
  3. Download www.balena.io/etcher/ select the image you just downloaded, the USB drive you just plugged, and click flash.
  4. Reboot and boot using the USB drive like you did for Windows 10.
  5. You’re now on Linux, feel free to just poke around, you can connect to your wireless, browse the internet and do whatever, just notice that anything you install or save will be lost since its not really installed but running from the USB drive. When you’re ready click the install button.
  6. Follow the on-screen instructions like you did with Windows 10 (or )
  7. Reboot and unplug the USB drive and you should now be in Linux.

As you can see it’s 99% of the same you did with Windows, the hardest part of it (boot via USB drive) you already know how to do.

Now, that being said I do have one small recommendation, while installing you’ll see this screen …readthedocs.io/…/installer-install.png I personally recommend you select the “Something Else” option there and manually partition your drive to have:

  • 512MB vfat (or fat32 not sure how the Mint installer calls it) partition to be mounted on /boot (this might not be needed, but if you’re in UEFI mode, which is very likely because the machine originally had Windows 11, it is needed)
  • 60GB ext4 partition to be mounted on / (this is your system, 60GB should be enough, but if your disk is large enough you can give it 100 or whatever you like, just bear in mind that every program you install will be here)
  • <Amount of RAM> swap partition (e.g. if you have 16GB of RAM then 16GB swap partition) (Swap is a place in the disk that can be used as RAM, you want it at least the same size as your RAM so you can hibernate the computer since RAM gets wiped when the computer powers off)
  • Remaining as an ext4 partition to be mounted on /home (This is where your data, games, photos, etc will be, having this in a different partition is the reason I recommended to go with the custom partitioning. Unlike Windows on Linux partitions are just folders, so if your data is in a different partition than your system you can wipe your system, reinstall it or even install a completely different distro, without touching your data. In short this means that even if you screw up and end up with a non working system, you can follow the installation again, ensure that this partition is not marked for formatting, and you should be back in a new system but without losing any data or configurations)

That’s just a recommendation for future-proofing, but if you just want to try it and are okay with wiping everything later if needed then feel free to choose the default.

Nibodhika ,

Yes, I use a swap file, but I don’t think the installer gives that option, so I’m trying to play it safe. Also a file will always write to the same part of the disk too because you allocated it first, but it’s easier to create another file and migrate to it.

Best Graphic card for Linux Gaming (lemmy.wtf)

Are they some graphic card benchmark for linux environment ? From my windows experience, drivers are important, and often underestimate. My linux gaming experience is very bad, lots of my game are unstable, and others use a lot more resources than with windows. However, when I ask people, some of them have no issue at all, even...

Nibodhika ,

Which GPU do you have? Which drivers are you using? are you sure you’re using those drivers and they’re not just installed but unused? My first guess is that you have an Nvidia and are using open source drivers (nouveau).

Some performance difference is expected, after all most games are being run through a compatibility layer, and many others were ported as a second thought so they’re not optimized on the same level. Also note that lots of us don’t use Windows, so we’re not comparing experiences, if it runs at an acceptable frame rate with an acceptable graphics settings for what I would expect the GPU to be capable of, then I don’t bother benchmarking it.

Nibodhika ,

True, but I don’t think it’s the case for OP since he reported less performance than on Windows, so I assume he meant on the same hardware.

Nibodhika ,

just making a docker compose and maybe having ansible deploy that?

that’s what I do, why ansible? Because it makes it easier to deploy the same service in different servers with slightly different configurations, for example when migrating from one server to another. Also it helps with having something I can easily backup (e.g. git repo) that can redo my server(s) if needed.

That being said I’m still setting everything up with ansible.

Nibodhika ,

Read what the other guy told you, see if your distro has a package for this instead of following the readme file, otherwise you’ll need to run that every time your kernel updates. There’s a reason we recommend people to use the package manager and to forget the windows mentality of installing things by random means.

Does color change how hot a laser can get something?

For convenience sake let’s say you have 2 identical lasers, one is blue and one is red. And you shine it on lead (so none of the light leaks through) until the lead doesn’t heat up anymore. Would the temperature change at all between the different color lasers. It doesn’t have to be red or blue, it could be microwave or x...

Nibodhika ,

This question has lots of different answers depending on exactly what you want to know, I’ll ask it in a few different ways and provide answers to them

Does the color of a photon change its energy content?

Yes, color is the result of how energetic a photon is, red is low energy compared to blue, so a single blue photon contains more energy than a single red photon.

Does the color influence how much energy is transferred to an object?

Yes, the color of an object is the result of white light hitting it and it reflecting back that color. For example leaves are green because they reflect green light while absorbing most others. In a way the color of an object is the color that the object rejects. So if you have a blue object it will reflect the blue laser more than the red one, so the red laser will heat it more because it’s being absorbed.

Which color heats lead the most?

That is a very interesting question, to know this you need to look at the absorption spectrum of the material, i.e a graph showing you which wavelengths are more absorbed by the material, so if I’m reading correctly the spectral lines in the wiki page for lead en.m.wikipedia.org/wiki/Lead it seems a cyan/greenish laser would be most effective in heating it (or I might be reading it completely opposite and that is the least effective color for heating lead)

Does a blue laser produces more energy than a red laser?

It depends, lasers emit photons, and while a single blue photon contains more energy than a single red photon, thousands of red photons contain more energy than a single blue photon. So it depends on how many photons each laser emits, if it’s the same amount then yes blue lasers will output more energy, but that’s not a given. In fact while I’m not intimately familiar with the physics of lasers, if we asume a perfect energy conversion from electricity to photons if two lasers use the same energy input they should have the same energy output, which would mean less photons for the blue laser.

Nibodhika ,

Yes, but the input power moat likely varies, and that’s because the energy conversion is not perfect, depending on the mechanics some energy might be dissipated as sound or most likely heat. But since I don’t know the specifics I can’t account for it, and it’s possible that red lasers require more energy than blue lasers because of a quirk in the way they’re generated currently. If we ignore that and imagine a magic box that can convert 100% of the energy given into specific color photons, for any given input it will generate more photons when configured to red than to blue, because a single blue photon contains more energy than a single red photon, therefore you need more red photons to get to the same level of energy.

All of the things others have said are excellent points, I would also like to point out that if you go to the steam hardware survey and select Linux only you’ll see that Arch is the most used distro (after SteamOS), and that was also the case when the Steam Deck was announced in July 2021 web.archive.org/web/20220806051441/…/hwsurvey/

And from my personal experience there’s a reason for that, other than the I use Arch btw meme, despite most ports having Ubuntu in mind, and despite Ubuntu being the more user friendly distro, games just work on Arch. It’s a weird thing where gaming on all of my arch machines is very painless, but gaming on the Ubuntu ones is frustrating, there’s always something not right, it feels like the machine is chugging, or the driver decides not to work, or the game shows a black screen, or prime decides not today, etc, etc. I admit this is personal experience, and others might have the exact opposite, and that this is kind of biased because as a general rule people who use Arch tend to be more knowledgeable about Linux than people who use Ubuntu, but from replying on several Linux forums it’s generally people with Ubuntu that have problems with games and people with Arch usually report that “it just works” for them.

Yup, been using Arch for around 16 years, never had a problem with an Nvidia card and the vast majority of my GPUs were Nvidia. Every time I hear the horror stories of prime and bumblebee I really couldn’t relate because everything just works for me… A couple of years back however my company gave me a laptop with a company approved OS (Ubuntu), and while I don’t know who’s exactly to blame here (but I have my suspicions), I’ve had to use prime-select to set the OS to work always with the Nvidia GPU, otherwise external monitors work like shit.

It could be that ThinkPads are shit compared to Acer (and every other brand I’ve had in the past) laptops, it could be that the i7 on that laptop has a shitty GPU and can’t handle the external monitors. But I’m 90% sure that if I put Arch there it would just work, and I wouldn’t almost burn myself with a 99°C laptop that’s constantly running a GPU that’s not meant to.

That reminds me Jedediah has been stranded on the Mun since around 2016, so I hope a long time hahahaha

I imagine you played the remaster on Steam, how did you defeat him though? In the original

spoilerYou had to plug your controller on the Player 2 slot so that Psychomantis couldn’t read your mind.

And that seems hard to reproduce the feeling on a PC while still giving everyone a chance to win the fight

I have been setting it up on my home, still not done but I can already see some benefits from it, e.g. I’m about to build a new server and migrate a lot of stuff to it, with ansible it will be very easy to just move some configs around and setup the server in no time at all. It also is encouraging me to keep a standard on how I do things which is great, and after setting up some initial things now adding new services is quite straightforward.

Overall I think there are a lot of positives about it, especially if you have multiple machines to manage. But even for a single one the fact that you can recreate everything from scratch in just one command is quite awesome considering the amount of times I’ve redone my server from 0 for different reasons over the past years.
