Comment Re:quickly to be followed by self-driving cars (Score 1) 904

If you're going to drop the value to zero suddenly, it doesn't really matter that much whether you financed or not. You still need to come up with the money to replace the car, whether you already spent the money or still owe some.. Personally, I've got insurance to cover the expense (minus the $1K deductible).

I still get a wee bit finicky about the word "MODEM" being thrown about. The is no cable modem nor DSL modem. In both cases the signal remains digital. MODEM is MOdulation and DEModulation. Whilst trivial it still irks me a little tiny bit but not enough to actually comment on it most of the time. That and, well, the options are a bit clunky to type or to say. Still, I prefer to use the word router, I suppose.

Art class was so very very long ago, likely before you were a mote in your father's eye, actually. I never took any of the arts classes in college - I did take creative writing and music classes which served to fill my prerequisites. Anyhow, I may be wrong. Isn't black the presence of all colors and white the absence of any color?

I could see using the RGB to create black but how does one manage to get a true white? It seems (I did not even do more than skim the summary) that there would need to be some filtering involved or multiple lasers.

Comment Re:DC power? (Score 1) 239

It isn't just line losses, it's also line capacity.

AC current isn't on steadily, and so the RMS voltage is about 70% of the maximum voltage. DC is steady, and so it can make full use of the voltage capacity of the line.

Another problem DC faced was switching. It has to be possible to turn connections on and off. It's harder when high voltage is going through, and AC has momentary zero-voltage points.

Most of what I know about electrical power transmission is from a job I had about fifteen years ago, so I don't know what switching technology is available.

Actually, scientists and academics have historically not gotten much respect. During and after WWII, there was a strong feeling that we needed science in the Cold War and Space Race, and they got a burst of respect, which seems to have run out. Anti-intellectualism runs deep in the US psyche.

Comment Re:CPR dates back to the 1700s. (Score 3, Informative) 43

I'd love to hear how people performed CPR in the 1700s. Did they have a clue what they were doing or were they just beating the Devil out of the man?

Jude was a member of a team of people who worked out compression frequency and breathing and then demonstrated that it worked on humans as an alternative to cutting them open and massaging their heart by hand.

Prior to that, people just blew air into you, then pushed on your chest to push the air out or moved your arms and chest around to get air in and out of your lungs. They didn't even think about trying to get your heart to beat for you, except maybe by accident.

If you're working on a solution for a user problem, then, yes, the user knows at least what the goal is. That's not how Apple became that rich.

Suppose Jobs noticed people with MP3 players and asked them what they thought would be better. They wouldn't have described the iPod. If he'd asked people with smart phones, they wouldn't have described the iPhone. The iPad is somewhat different, as I've seen a lot of similar concepts floating around (Star Trek, for example), but a focus group concentrating on designing Star Trek PADDs would not have come up with the iPad.

This approach has high risks and potential rewards. If you guess right, and Jobs usually did, you can just stand there and suffocate in the money people throw at you. If you guess wrong, you do something like write off nearly a billion dollars of Surfaces.
