"Works" is kind of generous. Try connecting a printer for example.

The article is quick to point out the huge role of oil in the modern energy mix. It also fails to note that most of the energy ends up us waste heat. The so called "Primary energy fallacy". Other than that, it's a great read.

There have been significant advances in power electronics and electric motors in the recent decades. Yes, there's not a lot to gain when you're starting at 85%+ efficiency, but it's far from "basic" technology.

What you're missing here is that oil production and processing has huge fixed costs. Producers can't just pump out infinite oil at zero cost. The economies of scale break down and fuels become more expensive as demand drops.

Why SSH to the build agent when you can run your actions locally using the excellent https://github.com/nektos/act

The problem with private address ranges is that everyone thinks they're available. In a large enough enterprise you're bound to have conflicts. They usually pop up at the most inconvenient time and suddenly you're cosplaying ARIN in your IT department.

I'm okay with writing developer docs in the form of agent instructions, those are useful for humans too. If they start to get oddly specific or sound mental, then it's obviously the tool at fault.

But you can compare generated power, right?

> In the 12 months to June 2025, wind and solar (2,073 TWh) generated more electricity than all other clean sources (nuclear, hydro and bioenergy) combined (1,936 TWh). Just four years ago, wind and solar generated half as much electricity as other clean sources combined.

Those are not really great construction examples, are they? Both projects took 15+ years to complete with huge cost overruns. And for those two "successful" projects, you can find 2 or 3 that failed.

Specialized EV tires are also optimized for drag and noise, wear is just a factor. Anecdotally speaking I'm at over 80k km on a set of EV tires with at least 20k more to go. The issue has more to do with driving style and engine power than any other factors.

No fundamental reason not to power them with renewables, either off-grid or with a small capacity grid connection. The argument that they need to run at full load 24x7 sounds more like a business requirement than a technical one. LLMs in particular with their stateless nature seem like an ideal candidate for global distribution.

The final analysis is still pending, afaik. In any case maintaining grid stability is a good problem to have and likely much easier to solve than generation. Worst case, you spin some flywheels to get inertia.

I'd really like to see the math on this one. It implies that building wind and solar on Earth is somehow worse than building it in space _and_ moving the data center there? It's not just counter-intuitive, it's bonkers.

Isolation is certainly one big reason to use jails. You also get independent management of dependencies, and can optionally share the base system.

They're somewhat similar to how you'd use Docker containers on Linux, but have different approach to security and networking.

You need a Solar Radiance map to say thay. Latitude is a factor, but so is climate.

Here's an example: https://re.jrc.ec.europa.eu/pvg_tools/en/

California and Arizona are comparable to Sahara, but Germany has much usable potential too.

This is not a general rule and many non-cooled and air-cooled batteries can hold up pretty well. The battery cooling becomes a limiting factor for DC charging, especially if multiple charging sessions are required per trip.

The Leaf limited battery life is mainly to its battery chemistry (LMO), although it arguably doesn't go to great lengths to ensure thermal stability of the pack.

This seems to be an UK thing, possibly to keep the sticker price below the 40k GBP tax limit. The option for a lifetime purchase supports this.

So it's an extra that you can try with a subscription and buy once, if desired. Seems fair to me.

Are you suggest they move them outside the environment? Sounds familiar.

EVs will maintain the battery temperature if plugged in, usually at 0C.

Even if not plugged-in they'll try to keep the battery above temperatures that may be damaging, e.g. -30C. This only works for a sufficiently charged battery.
