As a reference a new Cessna 172 is $432,000 [1] and that is not a high tech aircraft.

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, at end of life it burns up in the atmosphere. No worry about pushing the life on a component and having it crash and kill someone as a result.

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 more of a science experiment.

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.

Everybody seems to think that burying power lines is a walk in the park. It unfortunate the the conditions have changed were it is now necessity.

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.

Why not use dividends then?

Much of the proposed legislation applies to local governments too.

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 possible to prevent him from being acquitted, long after the new evidence was introduced.

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 is high enough above the atmosphere that minimal propellant is needed for orbit boosting.

Yes. There would be no need to be synchronized if the interconnect is only DC.

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.

As someone who is not all that familiar with education policy, is this basically analogous to for profit charter schools in the US?

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't remember a single weather cancellation.

The funny thing is I live further south now and when I go back to visit in the winter, it feels ridiculously cold.

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]

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 government aerospace programs.

It could. But so could a crash of a truck or a train carrying any type of liquid/gaseous fuel (e.g. truck carrying the gas to your local gas station). The article talk about LNG requiring thicker tanks than ethylene and ethane, both of which could also 100% explode if in a wreck.

I think the worry is that the volume of shipments for LNG would be much higher, and hence the probability of something happening is higher. A singular shipment of LNG would be no worse than a single shipment of car gas.

I missed it. There was really little news that this happened. Google's anti-hype approach to Waymo is interesting.

I would be willing to go together to have a set of PCBs if you are interested. Usually there is volume pricing.

Maybe because it's not an axiomatic fact. There has been niche radical internet communities for ages. It has only been with the radical communities coming into the mainstreams ones (reddit, twitter, and facebook)that the radical communities exploded.

What would you recommend in the x86 space?

If you take the average Oslo deaths over 2019 and 2020, which is 0.5, then London would have one order of magnitude more deaths per capita than London.

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.

U2F is freaking awesome. It's rare to have something which is both high security and not a pain to use.

I just wish the banking and financial industry would get onboard. For customer accounts, they are mostly using SMS, but some of them are still using personal info question (e.g. what was your first pets name) as a second factor which is horrible.

I could see Yubikey going to a NFC ring at some point. For PCs all they would have to offer is a USB NFC transceiver.

There are probably still some engineering challenges getting all the cryptographic functions and NFC power transfer into the form factor, but it seems like those will get easier over time.

It is interesting to compare the security of a yubikey+pin vs yubikey+fingerprint. Both provide similar and really good security compared to popular authentication mechanisms like static password, sms, and even authenticator apps.

But a sophisticated attack could still use your credentials if the yubikey was stolen, and the attacker had your fingerprint (plausible with the OPM personal info leak) or had captured your pin (maybe from a keylogger installed on a compromised device you had used).

It seems like the most secure method (albeit impractical) would be to have a "what you know" challenge built into the yubikey, like a pin pad or dial. At that point though, one would probably have to worry about other attacks, like physical intrusion and kidnapping as well.
