Could have been condensed a bit. Like, this has him saying the same thing n times, and that’s nice in that it shows it wasn’t a fluke, but then you run into the risk of TL;DW.

Yes, he was an extremist. And not the kind that’s intellectually honest about it, despite the marketing - you’ll notice he picked who got to ask him anything very carefully.

Of recent assassinations, it’s the least bad one. If you think that’s fucked up, refer to 4:30.

Because if my preferred side doesn’t, worse people will. (Although for all we know OP is Chinese or Russian)

If that sounds like a slippery slope, sure, it definitely could be. It doesn’t really seem like Canada is sliding into evil empire any time soon, though. And, when it does get to that point, they usually de-emphasise the idea of just war in favour of some version “patriotism”, anyway.

On pacifist grounds?

It’s really, really hard to say from just the airframe.

Now that the USSR is gone, and the files public, we know that the “Concordsky” was totally independently developed from the Concord, and completely different except on the outside.

If they did manage to copy the whole thing, that’s very bad news in any war with the West, because we’re not about beat them on quantity of anything.

Ah, good old Cunningham’s law.

Yeah, OP better prepare for some fanboying.

Except, we can’t ask too much, or we’re literally a less sexually appealing version of this meme.

Did you reply to the wrong person?

If not, the edit makes it pretty clear I’m not siding with Russia.

Although Ukraine also buys all their drone components from China.

Really, they’re just sitting back and making a profit.

Oh, come on, that’s one hell of a false equivalency.

Even WWI was basically different colonial empires fighting over colonies. You can’t really call them the bad guys before the Nazis came to power, and while people here will disagree which Germany was the better one afterwards, you probably like one of the two.

> Gives Israel a billion dollars, because they’re so sorry.

> Still elects Nazis.

Edit: Although, Jesus, people are big mad at them in here. Russia and “Belarus” are still the problem, and Germany is still a valuable member of the EU.

Thank you for the footnote. It could also have been pedantry, or the German system, where secondary courses have postsecondary-like specialisations already.

Ah yes, the famous 996 culture.

In practice, is it 4 hours of paying attention and 6 of going through the motions, or just goofing off? There’s been some research to the effect 8 hours already gives diminishing returns, if you’re doing something subtle or complicated.

Yup. In a car motor I’ve heard it performs better, as well. They went with a brushed design, IIRC, and have some kind of special sauce seal that makes that practical from a maintenance and robustness perspective, even if you’re on dirt roads.

Anyway, you just use an electromagnet where the neodymium magnets would have gone, basically. It’s has vaguely more geometry to it than a single permanent magnet, but that’s whatever. The other concerns are that you have to power it before you can generate any power, it can interact electrically with what it generates if it’s on the same circuit, and, if the rotor is an electromagnet, you have to transfer electrical power to that independently moving object. Those problems all can be solved one of a few ways, though.

From an outsider perspective, it sounds like the wind turbine industry locked into the permanent magnet design, because “rare earths aren’t actually rare!” and it’s easy. Now that the issues with that are appearing, they have all the typical retooling and scalability issues that come up when you want to change technologies quickly.

Fun fact: You can totally make a wind turbine without them, it’s just somewhat more complicated.

X to doubt, CNN/Brett McGurk.

Like, sure:

Wars are contests of leverage and endurance. And the contest now looks very different from even a few months ago.

But there’s no real foundation given for why Iran is more exhausted than America. Yes, more is going through the straight of Hormuz, and Iran’s still isn’t a global economic power. But, America is mostly out of weapons, and had no public support in the first place.

The language about how Iran “chose” to attack shipping is also pretty gross. It’s technically true, but the US chose to start this war, so it’s not like it was unexpected, unjustified or arbitrary. There’s also a part that’s basically “we can do it if we just believe”.

This bit is totally right, though:

A better American strategy from the start may have been an economic campaign to support the Iranian people demanding change.

If they had just said “men”, “women” and “low-intensity” or something, nobody would have cared. Now, they’ve pissed off every side.

I mean, if that happens once, sure. But whatever policy failing, and then people saying it just needed a little longer, is also a trope.

That may or may not apply here, before reading the article.

Ah yes, the famous problem of making everyone happy.

I guess if holding the trigger down for 5 straight minutes is going to be an absolute survival necessity in any war, WWI might be it. But it still sound unusual. 2 minutes does seem more realistic for whatever confrontation in nomansland, although if that happens often, having to stop and change barrels would really matter.

The thermal mass of steel is about 490 joules per kilogram per degree Celsius/Kelvin, for reference, while water gets 4181 at 25C. That means for the same capacity to absorb heat, you’d need to carry about 8.5 kilograms of gun barrels for every one kilogram of piss. Water cooling is so fast it’s usually treated as instant, so thermal conductivity hardly matters. Steel can get a lot hotter than water before it changes phases, that’s true, but at some point your barrel is going to have thermal expansion and heat softening problems, as well.

Well obviously, you should cool it with the other bullets, then. Maybe you could even collect the spent ones for that. /s

If directly using air is fast enough, sure, that’s a better option. I mean, in a water cooled gun, the water/steam itself gets cooled in the air, or on surrounding surfaces. It’s just an intermediary to increase effective surface area.

Not actually knowing much about the history of this, just the science, it seems likely that a barrel replacement was expected to be a rare event, because the rate of fire and heat per shot was low enough for whatever other engineering features to handle it, at least most of the time.
