Nobody makes big endian computers in any context where you'd use ZFS so thankfully this is not something anyone needs to worry about

ExcessBLarg! posted:I'm not familiar with this, but what I think you're saying is that the on-disk records for ZFS are in native endian format, but the import/export tools account for this and alter records as necessary. quote:ZFS is an adaptive-endian filesystem (providing the restrictions described in Chapter One) that allows for moving pools across machines with different architectures: little endian vs. big endian. The “E” portion of the block pointer indicates which format this block has been written out in. Block are always written out in the machine's native endian format. By account for it, do you mean like ZFS does? Because last I checked, you can't take any other filesystem created on big-endian and mount it on little-endian. Maybe that's changed, but it's not exactly easy to check given how little big-endian (ha) hardware there is. The only other alternative is ARM, but you'd have to have big-endian bootloader, kernel, userland, libraries, and everything else - and I don't know of any software stack that does that, and also has support the peripheral hardware (which better not include anything PCI or USB, since that's all little-endian) VostokProgram posted:Nobody makes big endian computers in any context where you'd use ZFS so thankfully this is not something anyone needs to worry about Nothing else can do that, even if there's absolutely no reason to do it today - because you could do it back in 2007 when it was entirely possible to move from big-endian SPARC to little-endian x86; I know, because I helped do that on at least one storage setup (and who knows, ZFS is entirely likely to survive to a point that big endian architectures could become popular again). cruft posted:

One time, $EMPLOYER built a big ol' supercomputer using Intel controller nodes and MIPS compute nodes. It went about as well as you'd expect that to go for doing pantloads of numeric operations.

I went to check the Linux source to see if I could find evidence of when conversion macros were added (if they weren't always there) and well, it's actually right at the top of the file. BlankSystemDaemon posted:Because last I checked, you can't take any other filesystem created on big-endian and mount it on little-endian. Like I totally buy this this was a problem with UFS, perhaps even for a long time. But sharing media across architectures has been done for a long time too.

BlankSystemDaemon posted:The thing is, unless you're a network engineer or a sysadmin with considerable amount of gray in a metaphorical or actual beard, you've probably never really encountered big endian outside of the network. I was reading the W3C standard draft of PNG 3rd edition and it was the first time I'd seen big endian referred to as network-byte-order. Now I see that TCP only uses big endian, that makes more sense.

How do you disable amplification of inputs with a default pipewire setup? It apparently thinks the Sound Canvas attached to my line-in is a microphone and I had to turn it down literally 57 dB to get it at a good level for loopback so I can play games with it.

I'm in a bit of a conundrum here. I have a Dell Latitude 7390 2 in 1 with Garuda Dr4gonized installed and working really well. Except it won't auto rotate with KDE Plasma. Any ideas or a solution? I've looked at the Garuda forums and can't find an answer.

Woolie Wool posted:And here you had me excited thinking the PS/2 had a unique VGA font when it's exactly the same as any generic IBM clone This came to be known as the VGA or VGA16 font (it's 8x16 pixels). I don't think it's ever been officially distributed as part of X11, but Linux does distribute it for use with the framebuffer console. The problem with the VGA16 font is that it doesn't cover much of Unicode. Some folks have gathered together as many of the codepages that were available and made Unicode versions of the font, including UNI-VGA and for a number of years this was the font I used with my xterms. It was still missing a number of glyphs so I gave it up when I switched my primary desktop to Chome OS about a decade ago. * Scalable typefaces, of course, are eligible for Copyright protection as the hinting system is driven by code distributed in the font that runs inside a VM.

I've used a couple of those extended VGA fonts before (mostly Perfect DOS 437), and I was wondering if any such fonts exist that have powerline characters, especially if they are pixelated to match the regular glyphs. Having the IBM VGA font with the chevrons and fancy colors would be funny as hell. It would be fun to

I have a media share I want to allow another person to upload files to. I'm running Ubuntu, I can foward ports with ease, they are savvy enough to connect to a well secured, stable method. Is SFTP the answer? Something else? I'm having trouble finding the right way to ask this question on google.

I think SFTP is the way to go because it comes free with SSH which you probably have or want anyway, and it's extremely simple to set up users and permissions for compared to normal FTP or SMB or others I've tried. Like you really just need to enable SFTP, then make a user for the person, and then give them normal write permissions where they need to upload stuff. However maybe don't make the default port visible because it will probably get hammered by driveby attackers. edit: does that apply to SFTP or just normal SSH? I guess an attacker can't do as much of interest if they only have an open SFTP port. BattleMaster fucked around with this message at 20:58 on Apr 15, 2023 |

SFTP, on a nonstandard port, using pubkey authentication and with passwords turned off, should be good enough for anyone not specifically targeted by nation states.

There's no harm in making it a non-standard ssh port unless you have some app that can't connect to anything that's not on 22. You can even define the port to use in your ~/.ssh/config file, so you never have to think about it again.

I'm having trouble finding the right way to ask this question on google. How often is he going to be uploading? Is he going to be downloading too? Literally the easiest and most cross platform way would be google drive or dropbox to avoid opening up your server with SFTP if you don't want to. Install google drive, invite him, let him upload. cp from google drive to wherever your "linux isos" are being stored. assumption that these files are under 1gb, if not you're gonna want more than sftp for large files like that as I recall sftp resume is kinda iffy. I’d go with rysnc over ssh for that. If you want a project. Minio does s3 and can do 50 tb buckets or some crazy poo poo. oh and use Tailscale so you're vpn'd together too jaegerx fucked around with this message at 00:14 on Apr 16, 2023 |

This is reason enough if the SSH doesn't need to be reachable by large number of people. At work we have a system that alerts if there are more than a hundred failed login attempts on a day. A server with 22 open to the internet get's 10k attempts, a high custom port gets reported few times a year. Theoretically SSH on a custom port is trivial to find, but no one bothers to go through the effort. If the admins were aware enough to use a custom port you probably wouldn't crack it anyway.

When I worked with some DOE national labs, they all used port 922 for ssh, but I never learned why. You had to auth your IP via an RSA token (it was a while ago…) before you could connect to anything, so they probably weren’t getting a lot of scans hitting the server.

Looks like the current SteamOS is based on Arch, so that might be what you need. Arch has a lean default install, so you won't have things like a GUI or audio until you install them. This also means you won't need to worry about tons of extraneous bullshit taking up disk or memory (until you end up installing them as part of a desktop).

Alternatively, if you don’t want to work your way up from rocks and sticks to a graphical browser, you can use something like EndeavourOS (the closest thing I found to SteamOS that didn’t make me flash back to installing Whoever’s Boot&Root off two floppies in 1992(.

As for distros, just go for one of the big ones at first - it means there's a good chance other people will have had your exact problems, asked about them online, and have gotten concrete and specific answers already. Ubuntu and Fedora are probably the biggest, and both should be easy enough to get working and let you do most things from the GUI. Steam works fine on both, too. E: neither are super slim with the default install, but give it a shot before deciding to scale down.
