Ummm… those are unfortunately the same part. The 905-belt is historically quite conservative. It’s the suburbs, which is where (many) people live.

for a more recent example, the American South’s narrative on the Civil War.

Bold of you to think that they would agree that it’s over.

I also use CodeFloe. While smaller, they have fewer guidelines around what is allowed to be there. While Codeberg is generally okay with people putting small private repos there, I don’t feel comfortable using what I view as a public resource for my private stuff.

(TL;DR: It would take >10,000 of the satellites described in the video just to move the two data centres studied in this paper to space)

I remember that video (been watching Scott Manley on-and-off since his KSP Interstellar series)

He’s right that you can cool 20kW just fine and I agree that 100kW is still very doable with today’s engineering. Let’s assume that a MW is also within reason, though I think we’re starting to stretch practicality there, as we’re now talking about about 2500m² of radiator if I’m remembering right. That would be 25 radiator groups, each one 5 times the size of an ISS group. I bet we could manage that with a few years of development.

The two datacenters that were studied in the linked article were 36MW and 169MW. So just to replace those two you would need 200 of those pushing-the-boundaries-of-human-ability satellites. Or, if you look at the Starlink-sized satellites that Scott Manley was referencing, you’d need OVER 10,000. And that’s just two data centres in one state in one country in the world.

I don’t think its “impossible”, or that “it can’t be cooled”. I think that focusing on the possibility of space data centres takes attention away from the harm that terrestrial data centres are causing today. “It’s okay if we build these on Earth right now, because we’ll move them into space later”? There’s nothing as permanent as a temporary solution.

Let’s force these companies to go to space by charging them exorbitant amounts of money to build terrestrial data centres to compensate for the effects that they have here. What would it cost to cool the areas around those data centres back down again? 100 million? A billion?

(And BTW, I’m a software engineer that’s been working in the AI space since 2018, before LLMs went crazy. I’m optimistic about AI in general. I’m pessimistic about companies that are clearly dumping externalities out into the general public.)

Wouldn’t it be a Groaniometer?

The issue with space-based data centres is dissipating that heat, though. The ISS radiators can dissipate less than 100kW and they are the largest in space today, IIRC. Current land-based data centres already generate 100s of MW of heat. US Datacentres alone already consume multiple TWh of electricity/year.

I’m all for space-based data centres. But I don’t believe anyone who says they’re coming soon. One small space data centre would be 10 ISSs—the largest space architecture project to date.

I think what people who are pooh-poohing on space data centres are concerned about isn’t the literal heat issue, but that it serves the same purpose as the “Hyperloop”: not a real practicality, but serves to focus lawmakers attention in a direction that ignores a practical issue (with Hyperloop it was away from California HSR, which now has its own problems, but at least it was feasible)

The primary issue is that there’s a limit to how much energy you can get out based on the difference in temperature between the cold fluid (liquid or gas) and the hot fluid. With data centres it’s maybe 20°C? Based on that assumption and the Carnot Theorem you get a maximum work extraction efficiency of about 6-7%.

Unfortunately, in the data centres they obey the laws of thermodynamics.

It would work better in places that get colder, but unfortunately places like that don’t tend to have as much available electricity (or infrastructure).

At my local CostCo, there is a pathway that cuts across each row of parking spots. At various points along this path are the cart returns. The path is constantly full of carts, meaning that you can’t get to the cart returns. I get way too bent out shape about his every time I go.

Tatrapay? Slovakia? (I know I could Google, but I’m curious if my guess is right)

When I clicked, I thought it was a cat/car typo joke because it’s a picture of a cat in a car.

Two things can both be bad.

Bad people can be right.

Saying “this video by the Iranian regime roasts the US regime” doesn’t automatically mean that the Iranians are right. I see the rebuttal that there’s an implicit boosting and platforming of this which normalizes it. I don’t know which is worse. I think we’ll need hindsight for that.

Common pattern - the acqui-hire.

“These people are working in a problem area that we want to do better in. We’ll buy their company for their expertise.”

Whether they keep existing products or not is not a major factor in the decision and gets evaluated later. Often, because they want the people working on something new the existing products are put into maintenance mode or shut down.

After the leaked memos from SCOTUS recently, I’m not surprised. LegalEagle video on the subject:

The controller was working both Tower and Ground frequencies at the time of the collision. At a busy airport like LaGuardia, that’s incredibly unsafe, IMO. Something grabbing his attention on Ground distracted him from this developing situation on his Tower responsibilities, and that’s all it took. He tried to then stop it, but it was too late.

He’s going to live with what happened for the rest of his life. I feel deeply sad for him. It’s not even really his fault. He was put in a situation where any human is likely to fail sooner or later.

The US’s air infrastructure (along with a lot of other infrastructure) has been going downhill since the Reagan administration. The US needs a 2-3x investment in the FAA 10 years or so ago.

I haven’t travelled to the US since Feb 2020, and I’m not going to (even for work) for multiple reasons at this point: the continued deterioration of the FAA’s systems is one major one.

From that exact page:

“Redistricted to the 33rd district but choosing to retire to run for U.S. Senate.”

While I think that this isn’t on target, I believe it to be mis-executed rather than misguided: I think they were trying to support their AI Coding Policy by removing any notion that Claude was responsible for the work (therefore leaving the human responsible). What it does in practice of course is just hide AI-generated code. Since the commit setting can be anything you want, I believe a disclaimer that the commit was assisted by Claude but that the committer is considered the author of the code would be a better choice (and I said so on the thread). I hope they improve their choice.

That’s the thing about authoritarians: they attract authoritarian followers (thought not exclusively). If the authoritarian at the top fails to recognize those of their followers that have the same traits and give them enough of a “fiefdom” to rule, then they betray. It’s one of the things that makes fully authoritarian rule fragile (most long-term successful dictators ensure they give enough power to the right people under them).

For those who don’t know, Bluesky isn’t really federated. The only way to host a non-Bluesky instance required 1TB of storage in July 2024, and 5 TB of storage in Nov 2024. Could be way more than that now.

You basically have to be a company to federate into the ATProto (Bluesky) ecosystem. You can’t just “stand up an instance”.
