Comment Something to consider (Score 2) 164

The only way you can lose heat in space is through radiation. But radiation carries momentum. Not much per photon, but it was enough to cause the Pioneer probes to move in unexpected ways. This means you have to emit equal amounts of heat towards Earth and towards space. If your resultant is zero, then you're fine. You can even direct some of the heat backwards. It won't do a huge amount, but every bit of atmospheric drag you overcome, the less fuel you need to use to stay in orbit.

So you basically need absolutely gigantic radiators behind the space-based data centre, located inside a parabolic dish that will generate drag of its own (not to mention a potential difference betwen the lower and upper sections).

This is an insane level of complexity. You're better off parking it in a stable orbit between the Earth and the moon, so it's absolutely clear of atmospheric effects. You're still going to need radiators, but it's marginally better as you don't have to do quite so much directing of it. The latency would be horrible, maintenance would be next to impossible, and there's all kinds of other issues to consider.

No, I don't think you can make this workable.

However, space might be useful. This very same issue of heat only being radiated means that you can make wafers with much more even loss of temperature, no dust, bacteria, or dirt, and much lower gravity. If you were to make extremely high quality wafers (silicon or gallium arsonide) in space, then you should be able to make WSI processors, which should in turn reduce the demands that datacentres make.

The time it would take to set all this up would be about the same time as it took for IBM to perfect its stacked transistor topology. Intel was talking 90 cores per wafer-scale CPU a few years back - the shrinkage in transistors since then plus the x10 density IBM proposes might push you to 1800 cores per wafer, provided you can get the quality high enough. Which, in space, is quite possible.

You wouldn't need your datacentres in space. Your wafer-scale CPU plus packaging would be about the same size as a CD drive. You could pretty much dispense with datacentres at that point. A typical tower will have two spare bays. "Cartridge datacentres" could simply be plugged in as needed. A regular CPU-based cartridge for heavy general-purpose computing, a GPU-based cartridge for LLMs. Yes, home users would have power usage through the roof, but then it's no longer your problem.

I guess that you conveniently forgot to mention the Southern Strategy to your daughter and what changes it had on either party.

On no, I didn’t forget, I told her that Democrats did not really run the Jim Crow South because the Southern Strategy retroactively changed all of that. I also told her not to look at things like black incarceration rates or the wealth gap since Democrats began paying lip service to civil rights, because, well, let us face it, it makes it look like they advanced their racist agenda far better while pretending to care about black folks. I also did not mention the largest expansion of the wealth gap taking place under Obama. Ditto the decimation of the manufacturing based that turned many inner-cities inside out. With supposed friends like Democrats, who needs enemies, huh? The Southern Strategy absolves all of that, though.

Do not worry, I told her that Republicans did all that stuff, especially after Trump led the bloodthirsty insurrection where he tried to take over the world and hold it hostage for one . million dollars, not to mention he let a bunch of filthy foreigners influence our elections, then forced Hilary to type a bunch of embarrassing stuff even though the real outrage was that the riff-raff got to read it. Since when do deplorables read, amirite?

I also did not mention the number of Democrats who anre self-described anonymous cowards. I figured that would just be going too far. Besides it would just be misinformation, or maybe a conspiracy theory.

Yeah, imma go with conspiracy theory.

I take it you're in favor of reparations, then.

If you’re offering, sure. Do you need to know where to send the check?

You apparently believe that guilt is carried by groups across generations, even when none of the current group was alive

You just described the basis of affirmative action.

Middle-range drones are in use because anti-aircraft measures have gotten so good. Once they've been depleted you'll see single-use drones replaced by reusable aircraft dropping dumb bombs again, which Iran did during the height of the Usrael attacks and Russia occasionally does in lapses of NATO weapons shipments.

Researchers in England found that they could track the US stealth aircraft outside one of the big bases by its affect on the cellphone network (IIRC it was covered on SlashDot). You can stealth them from the front and to a lesser extent from the sides and rear, but there's not much you can do about the bottom or the top.
