Nah mate, this now is who he always was.

Probably below average. AIUI, the Deck’s memory controller is designed first and foremost to feed the GPU. The CPU is reported to not handle great there, even if the GPU isn’t busy.

On the other hand, it is the most stable Linux system that I’ve ever had.

The energy consumption of replacing a worn out cable is pretty bad too.

The energy consumption of replacing a whole phone when the port wears out is considerably worse.

Oh and as a bonus, the wireless charger provides unbeatable isolation from lightning strikes or a defective power brick shorting to mains. I can’t say how many phones are saved that way, but it’s also something of an energy savings.

Legislating that everything shall be a $50 20Gbps cable stuffed with impedance matched micro-coax and shielding on top of shielding on top of shielding just means that nobody can afford it.

USB-C is not and will never this thing that you are imagining. It is one commonly shaped hole, with all the incompatible connections of yesteryear now lurking in a mess of unreadable symbols next to each port. This one can charge. That one can thunderbolt. These can send out power, if you want to use your laptop as a $2000 portable battery. This one sends out video, but wait it’s only HDMI, and only if that port over there isn’t using its superspeed lanes.

That’s usually the only way that backups will work.

I’m not talking about “resistance change in a cord blah blah”. I’m talking about the power and resources to manufacture and ship a new phone, after your old phone fails prematurely. The kilowatt-hours being poured into a phone’s battery over its service life are a miniscule part of its TCO. Doubling that makes it two pittances.

Has anybody mentioned yet that tar isn’t even a “compression format”?

For chocolatey, maybe. I haven’t seen a Winget GUI yet.

Microsoft really should do that, but I think the “but what about our App Store numbers” guys would rather that didn’t happen. I don’t believe that anybody outside of people who were already otherwise Linux users has touched winget.

Eh. By the time I have hardware that can actually play Starfield, it’ll be a GoG giveaway.

There’s a lot that goes into an Australian release. Shipping all those bits to the bottom of the world is outrageously expensive. All of the map geometry has to be altered to be right-side up there. The physics math has to be re-coded to deal with -1g gravity. Somebody has to be paid to go through all of the scripts to replace every instance of “jelly” with “marmite”. Asset loading code has to be changed to compensate for the Coriolis effect.

All of this adds up to expensive Au ports, the new costs often overshadowing the title’s original development costs.

It is amazing how every time you think “surely by now, I must have seen most of what Dave has to offer” it fires off another bonkers event.

The only system I have where X11 is still better is a Raspberry Pi. The whole Broadcom software stack there is horrible and should diaf anyway.

Your laptop is old enough that it’s probably not worth teaching the old dog new tricks. I have an 8th gen L480 that Lenovo already doesn’t want to sell a new battery for.

The desktop would definitely benefit from a windowing system that understands “multi-headed” beyond being one weirdly large framebuffer. Wayland is architectured to deal with multiple screens with multiple DPIs and different refresh times.

For gaming, Wine/Proton currently targets X (with magical Xwayland protocols to bypass the worst of it), but it’s going to be Wayland-native before you know it. Valve has a lot riding on making Linux/Wayland gaming better, and they’re going to keep on plowing development into that. Intel and AMD are 100% on the train, and even Nvidia is being less bad about it.

And a few hours later, 3.4.10 is out. This is already more OS churn than I want, for a game I that don’t have. :p

How do y'all deal with sleep states on modern laptops?

Most very recent laptops no longer support S3 sleep which used to be the default for a long time. On my old laptop it allowed me to just close the lid in the evening and open it again in the morning, and it would only loose a negligible amount of charge during that time....

I had to disable Volume Management Device in bios (a relative of Rapid Storage Tech, I think) to get any amount of battery life on an 13th gen Asus Zenbook. Learned it from bugzilla.kernel.org/show_bug.cgi?id=211879.

Look at “cat /sys/kernel/debug/pmc_core/package_cstate_show” (need root to even peek into the debug dir). If you only have C1 and C2 and everything else is zero, then you’re getting no S0ix joy. When things are working correctly, you should get some of the higher states, and a pile of C10 states when you close the laptop.

They removed S3 because Win 10 stopped using it. No OEM has ever read a spec such as ACPI. They only record the exact interaction with Windows, and make sure that the hardware works with that and to hell with anything else.

Oh, this is the first time I’ve heard of that. I use plasma-discover as my handy “search all 3 app sources at once” browser.

Try adding “PCIE_ASPM=off” to the kernel boot commandline.

rotopenguin,
@rotopenguin@infosec.pub avatar

AHAHAHA that is a proper insane bug. One PCIe device shouldn’t be able to slap others off of the “bus”, “we’re not on a bus all you did was mess up your own personal lanes mate”.

By the time you’ve dressed out an Rpi to be halfway usable, you’ve spent about as much as a decent NUC. And all you have to show for it is a slow-as-mud sd card, hardly any video acceleration, a USB stack that only crashes sometimes, a busy OOM killer, and no software.

Get an N95 based nuc. A Beelink with 8/256 runs about $150, and it just works. (Well, you might need pcie_aspm=off).

Do you have 3D accel enabled?

I’m so old, I remember when instead of “crypto” it was “Amway”.

99% of the time, that means SteamOS is getting sleeby and needs a reboot. (Some component of wine or something is not very good at cleaning up itself. You could try to chase it down, but trust me just rebooting is easier. Welcome to Linux.)

rotopenguin,
@rotopenguin@infosec.pub avatar

An intel 2TB (which is actually Solidgim) runs under $70. I sure hope it’s reliable.

As a btrfs user myself…

Yeah that’s a fair cop.
