Comment Re:i haven't bought a car in a while... (Score 1) 252

I think the point is price.

Cabs are expensive, but most of the expense is paying the driver. Once you get rid of the worker, it gets a lot cheaper.
Also, with centralized control, routes can be optimized so the taxis are always driving and carying passengers.
It's not slightly cheaper than driving, it can potentially cost an order of magnitude less, and be faster.
Where I live, public transport is easily 5-6 times less expensive than driving, combining bus and cab rides, including the labor cost of drivers.

About keeping it clean, and accountability, we are now used to be identified always. The cars can have cameras, and even require an id for you to ride them (they won't be taking cash, after all). There would be abuse, but it would be close to trivial to punish that kind of thing.

If there's vomit in the car, the car should be able to detect that, and go to a cleaning station. In the event that you do get an unsuitable car, you can just reject it. You could even look at a stream of the inside of the car before it gets to your home.

Also, think about the carpooling possibilities. While people don't like sharing space with strangers, price can change some minds.

Also, a "linux geek" would have already have taken dm-crypt as an alternative, or performed the instructions in some Full Disk Encryption Howto.

Isn't it built into the installer nowadays? I installed Debian recently and it offered to encrypt my system, but maybe it skipped the partition that holds /bin and whatnot...

You don't need to go as far as requiring equal pay. That can be your goal.
Knowing salaries is faster, and goes a long way.
If you are minority X, face discrimination, and are paid 80k instead of 100k for a white male, it will be hard to get that fixed, but knowing what others make will help you set your goals. Maybe you can get together with others and discover which companies discriminate the most. You might even find out that some company is not discriminating, just pays less to all their employees. Information itself is a very useful tool, and it's actionable right now.

Comment Re:Equitable pay? (Score 1) 430

A free market comes with the notion of a price equilibrium. Faster information means faster equilibrium, less room for inefficiencies.

Of course labor market is regulater by government so it's not really a free market. But witholding information from sellers only hurts a free market, as a whole. This makes it effectively a buyers market, which would behave closer to an oligopsony (https://en.wikipedia.org/wiki/Oligopsony). That's inefficient for the market as a whole.
 

Comment Re:Does indeed happen. (Score 1) 634

I've had other interviewers ask me really abstract problems, such as how to calculate the number and types of elevators a particular-sized building needed.

The answer to that kind of question is the same kind of concept as the Drake equation: the point is not to give them a number, but to give them a formula for how one might arrive at the number. In your particular example, the answer might be: ([# of floors] * [# people per floor] * [# times each person uses the elevator]) / ([elevator capacity] * [elevator speed]), or something like that (since this is not an actual interview, I didn't bother to account for things like the fact that traveling to higher floors takes longer, etc.).

The interviewer is asking you the question so he can see how you approach the problem, not to see if you know trivia about elevator design. Do you go make a list of everything you think might matter first, or do you dive in and think up new factors on the fly? Did you leave something important out? Are you able to make even slightly reasonable estimates? (For example, "I figure there's about a million floors in a building and 1 person per floor, each of whom is constantly riding the elevator so you need 60,000 elevators per building" is probably not going to impress the interviewer.)

Fast radio bursts: the observational case for a Galactic

Further, we re-analyze the probability that two FRBs recently discovered 3 years apart within the same radio be am are unrelated. Contrary to other claims, we conclude with 99% confidence that the
two events are from the same repeating source.
