@ShamashAran @ddankenst The heatpump-based electric water heaters are pretty good and widely available these days. I'm not sure there is ROI on them if your older tank is good, though. If you're in a climate where you need more AC than heat might pencil out...

@esrtweet I don't understand how we ended up in this absurd situation where we have a stable kernel API but not for userspace! At this point I'm afraid our best hope is that Valve will fold something like kubernetes into steam and shove it down everyone's throats...

planefag, I'm not excusing the attitude of the guy who pissed you off. But there is an explanation for it, and I'm going to put on my Mister Open Source hat and lay it on you. The real reason there aren't prominent links to downloadable binaries on forge sites like GitHub is that in open-source land there is no such thing as a truly portable binary. Windows and Mac make binary distribution easy by being limited to a single hardware platform and a single ABI - application binary interface.. (The assertion I just made can be quibbled with at the edges. I will be unkind to anyone who attempts this.) An application binary interface is a set of conventions for how you decorate your binary so the operating system's program loader knows what to do with it, and how you write traps from your binary to call operating system services. Windows and Mac have, effectively, just one ABI each. So you can generate one binary for, say, Windows, attach it to a download link, and Windows users will generally not come back screaming for your blood because it fails to work in some obscure way. (Again, this statement can be quibbled with, but see this whacking great truncheon in my hand? Just don't.) There is no such grace in open-source land. There are a whole bunch of complicated historical reasons for this, starting with the fact that Linux runs on more different hardware architectures, and continuing with the fact that Linux isn't the only game in town (there are the BSDs), and continuing into technical minutiae that would make your head hurt, and continuing further into technical minutiae that make *my* head hurt. But what this actually means is that if you want to provide binaries and not get sperg-screamed at, you can't just provide one. You'd have to provide many, and no matter how comprehensive you try to be somebody is going to be disgruntled because you didn't cover their corner case. This is not a cost-free proposition. For each different kind of binary you provide, you need to cross-compile your source code in a different environment, many of them posted on distributions and hardware platforms you don't have routine access to. So people almost never do it at all. Because most projects don't do this, sites like GitHub don't see any demand push to make binary download links really accessible. Instead, the problem is normally handled at a different level. Your distribution maker keeps huge sets of compiled binaries lightly hidden inside of installable packages, tuned for the ABI of that single distribution. Your package manager hides from you the packages for everything but your hardware architecture The person who pissed you off was rude, but he wasn't exactly wrong about the objective facts. What you want isn't practically possible. Instead of being annoyed because GitHub doesn't feature binary-download links, search for that software using your package manager. Sometimes you won't find it. That's when you have to download source bust out a compiler. Sorry, but that's the way it is. We're trying as hard as we can - really, we are. But the complicated shape of the terrain constrains what we can achieve.
planefag@planefag

This is the exact kind of guy I'm talking about btw. I'm arguing that Github could stand to put a few hyperlinks in more visible places on the page and he's acting like I'm demanding the fucking firstborn of every FOSS coder in existence. Theater kids

@spikesguides It's 40% that, the rest is life support for defense contractors building overpriced rockets who were working on the Space Shuttle program in the 1970s. If that means ever gets cleaned up NASA will get sooo much done.

@esrtweet The Woburn Municipal Waterworks museum outside Boston MA has three generations of giant high end steam engines from the late 1800s to early 1900s IIRC. Well worth a visit if you're in the area and especially if you can get the guided tour.

There's an obvious business opportunity here. 1. Pick a time-to-manufacture figure that you want to achieve that is well under 4 years. 2. Go through the history of gas turbine designs. Find the most recent one that achieves the maximum time to manufacture you chose. 3. Revive it. 4. Profit. Yes, you will trade away some fuel efficiency. But there are obviously lots of customers who will take that trade because otherwise they get nothing. Optimizing for efficiency was the right choice when demand was lower. Now it isn't. Somebody can make fat stacks of cash by recognizing this.
Gaurab Chakrabarti@Gaurab

You cannot buy a new gas turbine until 2030. Order books at GE, Siemens, and Mitsubishi stretch to 2029. Turbine prices have nearly tripled since 2019. Every AI data center needs power and every gas plant needs a turbine. And every turbine has one part that bottlenecks the entire industry: The blade. It has to survive in gas 500°C above the melting point of the metal it's made from and spin at up to 20,000 RPM under 10,000 g of centrifugal force. Each blade is grown as a single crystal of nickel superalloy, pulled through a vacuum furnace at 3 mm per minute. A set of blades costs $600,000 and takes 90 weeks to grow. The same metallurgy powers modern jet engines. Only 3 companies on Earth can build one. China spent $42 billion trying to catch up. They bought a Russian fighter engine, took it apart, and copied every part. Their copy ran 30 hours between overhauls versus 400 for the original. Modern Western engines run 4,000. You can reverse engineer the shape of a turbine blade. You cannot reverse engineer 60 years of metallurgy.

@esrtweet As more and more gas generation comes online, efficiency will be important as the price of natgas is headed for a new trading range. I would posit that additional capex will be better invested in nuclear, which is what appears to be happening.

@hackaday A different discussion here recently discussed why vivid green is the color of poison in western media (but instead purple in Japanese!). I wonder if there's an association there that those greens convey danger and a sort of underhandedness...

We'd love to see a PhD thesis on why green-on-black terminals are more "cinematic" or "hacker" than amber, which was well represented in the actual technology used in past eras.

Occurs to me today that I don’t actually know what diesel is with any specificity. It’s, um, kind of like gasoline but also different? Trucks use it. And Europeans? Freight trains?

@sebuahtujuan @REM__BEN Actually, rifles have less range - they're literally moving so fast that the water can't move out of the way and it's just an explosion. Only projectiles travelling less than the speed of sound in water will travel any meaningful distance.

@REM__BEN Yes, you’re mostly safe underwater. Bullets slow down extremely fast in water — handgun rounds stop in 1-2 meters. Rifles go a bit farther but still die quickly. The video shows exactly that. A few meters away = safe. Point-blank = risky

It blows my mind seeing the engineering boundaries that were being pushed in the late 40s and early 50s. Northrop's YB-49, a heavy flying wing strategic bomber prototype, looks like something out of science fiction.

@PhoebePlague Nah, this is just a big ion thruster with a nuclear generator, it doesn't get near the league of crazy concepts. Vaporize the lithium by running it through the nuclear reactor and we can talk.

gpt-5.5 prompt for codex seems to have a duplicated line trying to get it to not talk about creatures?

@TomChivers I wonder if this is higher in the UK than US; IIRC a recent meta survey showed male/female political differences among the young by far higher in the UK and Korea than in other developed nations.

This seems really bad and I don't know what to do about it: not so much the differences in political attitudes, that's fine, but there's a strong gender divide in belief on straightforward factual questions like "is nuclear energy low-carbon?" yougov.com/en-gb/articles…
