The U2 was subsonic. Also, un-powered gliders can get up to impressive altitudes. https://www.airbus.com/newsroom/press-releases/en/2018/09/ai...

As a reference a new Cessna 172 is $432,000 [1] and that is not a high tech aircraft. [1] https://www.forbes.com/sites/erictegler/2021/04/28/prices-fo...

The U2 operated at over 20km, so maybe the altitude is higher. I suspect the greater issue is vehicle cost, lifetime, and safety. A starlink satellite is much smaller (and as result cheaper) and is rumored to have a 5+ year lifetime. Also,

Who knows. The problem is not getting fusion, but getting fusion to economically produce power. Hopefully one of the startups figure out some way to make it work. I have a hard time seeing the NIF approach becoming economical. It's mo

Aluminum and steel actually make quite a bit of sense to recycle. The big energy cost is in the processing of ore to metal. Re-melting the metal is relatively low energy.

The underwhelming part is that it took so long. The first private manned suborbital flight occurred in 2004 with SpaceShipOne. It is 17 years later at this point and only now do we have paying customers for sub-orbital flight.

Sounds kind of like how one can grow one's money by investing it in an index fund and sitting on it and how rich people can get richer with no income and a passive investing strategy.

Highly recommend the book "The Sun Does Shine", by Anthony Ray Hinton. He was wrongfully convicted and spent 30 years on death row. One of the crazy parts of his story was how the state dug in its heels and did everything possibl

Why don't people make the effort to just move to Debian Stable? If you don't want to pay any money, relying on Redhat's goodwill always seemed precarious.

Wikipedia to the rescue (note the log-log scale) https://en.wikipedia.org/wiki/File:Spacedebris_small.png The biggest issue is by far the 600km to 2000km altitude band. It is popular for both LEO and SunSync sats and

Interesting. I love hunting and fixing significant bugs or issues. It could be because the immediate dopamine hit if successful. Harder to get motivated for things with less certain impact, even if successful.

I grew up biking to elementary school in Sweden year around and it did not seem like a big deal. Just make sure to dress for the weather. I remember wearing overalls or ski pants when it got real cold. Snow days were also not a thing. I don

I don't understand the heartburn people are having about this. If you want to use a free distro, why not just move to one of the many distributions which are not tied to a for profit company?

For U2F specifically you don't need apps except support in the browser. The apps you listed are used for other types of functionality provided by the yubikey, like OTP and TOTP.

Fully agree that a physical attack is much less likely. Also, the use of a PIN or fingerprint[1] to authenticate the yubikey itself and not sent over the network, mitigates the stolen key scenario. [2] [1] https://www.yubico.com&

To me this is more of a NASA thing. If a program ends up going over budget too much it gets cancelled. But the need is still there, so new program is often started up with a similar set of requirements. This problem is endemic across gov

No. Carbon dioxide will still be in the air when the aerosols settle. The collapse of the global economy will limit the addition of more carbon dioxide though.
