All crypto is difficult to get right unless you're a crypto expert. RSA is not unusual in this regard. The thing that is unusual about RSA is how many people /kind of/ understand it. Crypto people who dislike RSA say that thi

My suspicion is that SpaceX and the ESA disagreed either on: 1/ the position of the SpaceX vehicle (ESA may not trust the SpaceX position data) 2/ that they disagreed on the probability of a collision (ESA thinks it's 5%, Spa

Definitely GPS, probably star trackers too. Not a good idea to have a single point of failure on position knowledge when your whole scheme depends on putting small beams in the right places.

Why is it neither interesting nor concerning? From a security perspective it would seem to be both-- hostile firmware could at the least read secrets from your screen, and I'd be shocked if it couldn't convince the corresponding k

This is a very good analogy for a concept I've tried to formulate succinctly spur-of-the-moment a few times. I especially like that it captures the reversibility of the trend and the energy cost of doing so. Thanks for sharing.

So, I note you've gone from "it can't be done" to "it can't be done well". And yet, Equifax is unquestionably less abusive than it once was. It still exists and still makes money. It's clear that legi

Yep. The difference is in what they don't do anymore. Once upon a time they literally collected rumors and sold them, and took great pains to ensure that you couldn't see what information had been collected or sold about you or to

If someone spent decades exploiting vulnerabilities to the point where they made a billion dollars shuttering hundreds of healthy companies and costing thousands of people their jobs, that person would either be very quiet about it or in ja

Equifax may not be a great example here, since Congress already stomped on it explicitly because it was concerned about the privacy implications of digitizing the information they held. That fear led to the Fair Credit Reporting Act, which

Lots of reservoirs or mining pits basically aren't suitable for life, and there are even more bodies of water that have areas that aren't. Sometimes that's because of pH or salt concentrations, but more often it's becaus

Seems like you'd be much better off floating them on a lake. There was a project a few years ago to do this both for power and to reduce evaporative loss in reservoirs, but I don't know if anything has come of it.

The power to make law regarding wolves already belongs to the state, as grey wolves lost federal protection earlier this year. Independent of that, ranchers are compensated for killed, wounded, and spooked cattle under the pay-for-presenc

Makes me think a better idea would be to 3d print something like a ceramic outer shell and just fill the void with casting grain. I assume there's some reason you can't print thin layers of clay and then bake them under the print

The book does have some discussion of labor, but essentially alleges that the US labor movement is dead and new ways of thinking about the problem will be needed to wrestle with the problems of labor in the modern environment. I tend to agr

There's an interesting discussion in this about how early market advocates assumed that in a free market almost everyone would be essentially self-employed, and how the industrial revolution broke that. It's especially interesting

Even the idiots on YouTube are mostly smart enough to pack it in once they get too much attention. An installed device does not have that luxury-- nor, under your argument, should it need it. If your claim is that you could stand outside a

The really nasty one is compromising the return supply chain. Many (especially unopened) returned electronic devices go right back into the supply chain. For many retailers it's literally a free attack to carry out, with the only downs

Public nuisance laws already on the books would likely do the trick. To use your example, it is already perfectly legal to own a bullhorn and even to carry it around downtown, but if I start setting it off outside a restaurant I'm goin

The same way they do a bajillion other products? You make it illegal, then you fine anyone who flouts the rule or throw them in jail.

Not disagreeing that they has a long way to go here, but Amazon beats 100-year-old companies on their core competencies all day, every day. I'm not sure the history will save UPS in the end.

Minkowski blew my mind when I fist started to understand his work. Without a doubt the most useful pieces of math I learned after multiplication, and more intuitive even than that.

We have a system where you can go and see a webpage say your vote was counted after you mail in your ballot. What you can't do is tell if that webpage is accurate. This still feels like a tractable problem in the domain of pure crypto

I'm confused. First, Android is a Linux system, and underneath the app framework is really a pretty normal one. So I'm not sure what distinction you're drawing here. Second, the grouping of related syscalls is something SEL

Ok. It isn't in permissive on Android, and there's a CTS test for it.

The point is you need the ability to express both "these are the same thing" and "these are different". You can do both with SELinux. What's your alternative?
