See this comment for math and specifics: https://lemmy.world/post/38090104/20233592

But the TL;DR version:

• Launching anything into space is heinously expensive. And CO2 emissive.

• With very generous math, you’d need a radiator like a mile across to cool a space data center, but practically? Larger.

• Datacenter hardware is unreliable and goes obsolete quickly, and any kind of maintenance in space is basically cost prohibitive.

• There are other smaller yet still crippling engineering challenges, like bit flips from radiation (which gets move severe as lithography shrinks; look up Nvidia’s research on this), assembling large structures in space reliably, cooling loops for such gigantic structures, and extremely difficult/expensive networking (with distinct issues in LEO or geosynchronous).

And most of all… Solar is dirt cheap on Earth, compared to that.

So is just sticking a pipe in the ground for a geothermal loop, or ambient radiative cooling. We literally have tons of mass to dissipate heat into for free, instead of having to radiate it thermally, yet that’s too expensive for ground data centers, apparently.

That’s the joke.

It’s like saying “air conditioning is difficult” and proposing “I know! Let’s live under the Antarctic ice sheet!” That’s not hyperbole. It might be more practical, actually, as getting mass there is waaaay cheaper…

To answer your question, it’s very hard at that scale/temperature: https://projectrho.com/public_html/rocket/heatrad.php

The really hilarious thing is evaporative cooling (that takes so much water) is simple penny pinching over a closed loop system. That’s all.

…Yet Bezos and Musk are talking orbital datacenters?

Pick a lane?

And KDE’s RAM usage is very reasonable these days, especially if you opt out of some of the bells and whistles.

I use KDE with Krohnkite.

E.g. I have my cake and eat it, as windows can get dragged around if I want. Anything weird is just windowed like normal KDE.

Works with mice, and works good OOTB!

Hard disagree.

Installing Debian on Nvidia means you are maintaining Nvidia yourself, and you are just holding your hands together hoping the 3rd party repo’s don’t fall out out of sync and you don’t have to troubleshoot some Nvidia conflict yourself. This is the whole reason I left that ecosystem behind, it was a huge waste of my time…

…Maybe you got lucky and just didn’t run into any Nvidia bugs? But that was not my experience.

(And to be clear this is different if you’re using it headless or something).

Sounds about right.

Does any Mexican press point this out? The Guardian certainly doesn’t.

Eh, maybe that’s fair. Especially this:

doesn’t automatically mean he’s never been an engineer.

Maybe he was quite knowledgeable… On the other hand, I thought his old ‘Mars Colonization’ talk was bonkers too. I can’t remember what year it started, but it sounded like he had little understanding of the impracticality.

It must be bugged and busy-looping in the background.

I will say it again:

Musk is not an engineer. E.g. he has not played Kerbel Space Program.

He demonstrably does not understand the tyranny of the rocket equation, and how obscenely uneconomical getting anything to, and doing anything in, space is: https://en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation

Geoengineering is something worth seriously discussing (and TBH I hope he draws attention to it), and “solar shades” are theoretically neat, but this is not the way. Not with the trajectory of launch tech we have.

Yeah. Talking about geoengineering is great.

“These are not nuclear explosions. These are what we call non-critical explosions.”

FYI he’s referring to nuclear “criticality,” e.g. testing the non-nuclear explosives placed around core. To simplify, the yellow stuff here:

…That is totally fine. It’s a good idea.

It’s also a great escape from what Trump said. If you’re energy secretary under Trump, this is exactly how you get out of this (and just hope Trump doesn’t notice).

JC2 multiplayer was tons of fun.

They could make a mod for a newer game to drive up sales. Not like a hardcore game mode, but a big sandbox to mess around in.

I mean, all voice streams through Discord’s servers. It’s not P2P. So there wouldn’t be any proof outside of their wording in the ToS.

Here’s what I’m talking about:

And again, I think “use Discord for text, but use this for voice” is a much easier ask than trying to get them to login to some other chat app.

Ehhhh, Krisp is the least of Discord’s privacy problems. I’d say start with all its monitoring of what you do on your system as low hanging fruit.

That being said, try to get all your friends to switch to SonoBus for voice chat, strictly. It’s awesome! It’s way lower latency (so less talking over each other), clear, point to point, dead easy to start since it doesn’t need an account, customizable for quiet or noisy mics, works on everything, I could go on and on.

…As opposed to what? Mass killing of Muslims?

Ebay?

I’m in the same boat and considering this.

I tried to look up Putanism and the associated ideology. Shrug.

I’m not saying it’s authentic, but a lot of stuff seems to be cloaked in Soviet nostalgia and collectivist, anti-capitalist ideals. Hence, tankies.

…Isn’t Putin’s Russia ostensibly authoritarian leftist?

EG they are philosophically against individualism, materialism and such, kinda like Soviet Russia?
