USB 5V power can be equally noisy, even from a powered hub, so that argument doesn’t make any sense. PCIe has a high current 12V rail available that has much more margin than USB for filtering with an LDO and run your signal chain well above the noise floor of the components.
Besides, Asus Xonar as in the picture can take 12V from a drive connector to bypass the motherboard PCIe 12V “just in case”.
Next week: Fedora meets a new friend named Lennart while on her way to Multiuser Mountain. Will they be able to cross the init bridge without being caught by Sammy the Systemd Hating Troll?
Then they trip balls, see their life flash before their eyes, and become a space baby. Could be worse.
So say we all.

That’s exactly what they are, but instead of connecting to a VAX at the other end of a modem they talk to a shell attached to a pseudo terminal device on the same machine.
25 years ago I worked at a university computer lab that was Windows-heavy because Dell wouldn’t stop donating PCs. However we didn’t have enough UNIX workstations as we had to pay for Sun / HP / IBM out of pocket. Converting them to Linux workstations would be nice because the Dells had more grunt than the aging RISC workstations.
I proposed to switch a few desks worth to Debian and was given the go-ahead. After a few days learning how to preseed an installation image and getting a PXE server going I had 8 machines running CDE just like the AIX and HP/UX boxes. Users that didn’t need one of the commercial engineering applications tied to one OS or another didn’t notice any difference between the free (now as in both speech and beer) Dells and the proprietary workstations.
A couple of months after we got the pilot rolling, the university’s IT director came to check it out and told me we’re on the “lunatic fringe” for deploying an OS developed by volunteers, but otherwise offered approval as long as we could maintain security and availability.
Now every student in our local school district gets issued a Chromebook running Linux under the hood. Who’s the lunatic now?
It’s not known to be a backdoor, but it’s a juicy attack surface that customers are largely ignorant of and provides little consumer benefit. If I were an NSA employee and my boss handed me a blank check to develop a preboot exploit for Intel PCs, I’d start with IME.
Sometimes EDID eeproms are writable from i2c-dev… And sometimes VRM configuration ports too…
IME is even worse than that. It runs on a supervisor processor in the chipset that has privileged access to the memory, peripherals, and CPU, and can run when the rest of the system is powered off. IME is how Intel AMT can serve as a KVM-over-IP, and just because you don’t have a CPU with Vpro doesn’t mean all the components aren’t there for an exploited or backdoored ME firmware to remotely log your console or inject keystrokes.
20 years ago the pocketable digital cameras that took over the consumer market didn’t have hot shoes. 30 years ago the compact point and shoot viewfinders that were the weapon of choice for vacationing didn’t have hot shoes. Today neither are relevant and are all outclassed by smartphones, and there is hardly a consumer camera market.
You don’t have to spend five figures for that exposure, but it’s going to be an intentional hobby.
The intersection of people who aren’t five figures into photography and know what a hot shoe is, and people who recognize a wall mount phone trend old.
If I couldn’t wear fuzzy socks and sweaters at work I’d just quit.
There should be a setting in BIOS for sleep state that lets you choose between “Windows sleep” and “Linux sleep”. I know I have to set that to “Linux sleep” on my P14s gen 2 AMD or it wakes up immediately after going to sleep. Updating BIOS and the other firmwares might help too.
However I have a gen 7 from work running Windows that often fails to wake up from sleep or hibernation, and I have to resort to poking the reset button to get it to respond. Coworkers report similar troubles so I think it may be a cursed model.
That said, I’m running OpenSuSE Tumbleweed KDE on my P14s and an X1 gen 5. Everything works smooth out if the box on both machines except for the fingerprint sensor on the gen 5 which doesn’t have mainline fprintd support in any distro.
I never used Itanium, but I’m guessing that the Alpha workstations also ran x86 code faster than the Itaniums. fx!32 was one of DEC’s marvels that they completely forgot to market.
Similar, but not the same. The biggest difference of course is that the MIPS ISA is still commercially licensed while RISC-V’s ISA is open.
Tumbleweed is boring, and that’s why it’s wonderful.
If you’re piping any of those commands to or from awk, you can also go.
