Japanese solution -- I saw a YouTube video on how the Japanese addressed this by elongating the nose of the Shinkansen. That design was inspired by the kingfisher bird diving in water. The length of the nose helps to gradually displace the air as it enters the tunnel, reducing the strength of the pressure wave.

Also, perhaps fans could be a solution. Powerful blowers that push air out one end of the tunnel, just as the train enters in at the other end, then taper to zero as the train exits

Perhaps you'd like to live in China or North Korea where you can be randomly apprehended and harassed by the police just "because you look a bit sus".

Versus the United States, where a US citizen born in the US can be deported to country they've never been to, where they don't speak the language, just because they look like an illegal immigrant?!

I don't like communism or socialism, but I can't deny that the Western world is having a Soviet Moment, with Britain and the US leading the way in violating civil rights.

Thank you..

This post is worthy of a slashdot story, all by itself.

If the Earth identifies as a cool planet, who are we to say otherwise?

Every perspective employer will look at your experience and they will agree that you're valuable and capable of doing good work and profitable work for them but they will also fully expect you to hang around just long enough to get a little bit of experience and then leave.

What this implies is that as soon as someone gains valuable experience, every other employer in the area is willing to offer them more money. Which says very loudly they want to pay below-market rates for labor, and they don't give raises, ever. If I could take a year of experience and make more money anywhere else, nobody at the company is paid for more than a year of experience. Your kid trained for a career with no future.

Like most, I didn't go to college for four years to get a career that didn't pay raises past the first year. I suspect your kid made a bad choice of career field, because apparently - as you describe it - none of the employers in the field want to pay for more than a year of experience. This is precisely the attitude (and employers) graduates are hoping to avoid by getting a degree. Nobody puts in four years of effort with the expectation that they'll be treated like unskilled labor. Yet this is exactly the employer attitude you describe. People have started to realize that the problem all along wasn't a matter of skilled/unskilled labor, but that employers viewed employees as disposable, and rather than train them, made unreasonable demands in the first place.

The problem isn't whether or where you got your degree, but the attitude toward employees imparted by the CEO's alma mater.

As long the settlement is near the lunar poles, maybe panels on 10m poles could do the trick?

This war is not going well for either Russia (122K+ confirmed deaths; Mediazona) or Ukraine (77K+; ualosses.org). Many soldiers no longer want to fight. What is glorious about forcing more men to early deaths?

What's important is an immediate ceasefire and a process for both sides to punish war crimes committed.

I am heartened to see Trump pressuring the Russians into ceasefire... that instinct of his is correct.

But he's famously unreliable with numbers... I wouldn't grasp at that particular straw as a continue the war.

Both sides need to reach 0:0 ASAP.

Russia officially wants 20%. Stick to the current facts.

Ukraine could have got away with a much smaller percentage at Istanbul. But they took your advice. A half million casualties later, they have wisened up.

20%.

If thugs took 17% of my home, battered my family to a pulp, but my friends just kept mailing Amazon packages to me instead of showing up, i would appease the thugs with 20% of my home. So my family could live and have a roof over our heads.

So the answer is 20%.

But sssh... don't tell the thugs..

NASA has been able to make rockets that don't blow up since the 1960's.

Why can't the Australians do it? Was that knowledge filed away in a locked cabinet somewhere, or has rocket science made no strides in the past half century? Why isn't rocket design a "trivial" problem in engineering?

If they took the same approach to computer science, the Australians would still be trying to refine silicon from sand.

> Why aren't you calling for Russia to give up more land?

I would, if it would help the cause of peace. But it won't. So I won't. Instead, the most we can do is ask Russia to accept the land it has taken so far, plus some minor concessions (like Pokrovsk) and freeze the conflcit.

> How quickly you changed you mind.

My position has been consistent. I have lived in a land of a frozen conflict.

When this war started, you were enraged (justifiably) at your sense of justice being trampled upon. But I get the sense you are also speaking from ego now - your predictions and exhortations have been proven wrong by reality, and you don't like it.

> Don't Russian lives matter?

Don't all lives matter?

In a war with a million casualties, the easiest thing for foreigners to do is exhort one side or the other to keep spilling their guts. Both sides have millions of families with a serious loss -- there is enough anger to continue.

The harder, but more correct option, is to push for a peace that stops loss of live,and protects both parties from further losses. The most likely option for this is (a) asking Russia to accept the land it has taken so far, (b) some minor concessions from Ukraine (like Pokrovsk) and (c) freeze the conflcit.

Guts and glory stories are easy to recount when the spilt guts are not yours.

Remember, you or I could be born a desperate Russian or Ukrainian draftee. If you want to help, push for peace.
