Comment Re:Memorizing site-unique passwords isn't possible (Score 2) 267

Yeah, the suggested method for generating passwords generates needlessly long passwords. The total entropy is good, but the entropy per character is pretty poor. You get much better entropy per character with abbreviation passwords, where you have a sentence or group of random words and you use the first letter from each, or second, or last, or alternating, or whatever suits you. It's still not as much entropy per character as a random pattern, but it's much better than writing out full words - and pops into your head just as fast (because it is, in essence, the same).

What does "password strength" really mean?

If people used a textual representation of number obtained from a reliable hardware random number generator then the meaning would be unambiguous. It's the number of digits in that number. But most people don't do that (perhaps more should).

So what does it mean to say that a password has so many bits of entropy? Well, I guess it means how many truly random bits it would take to index their password from the universe of passwords the user considered. This is more an exercise in psychology than it is in mathematics. You have to figure out how users generate passwords or discount passwords. For example requiring a mix of upper and lower case letters doesn't add as much entropy as you'd think, because most users are mediocre typists who'll avoid using the shift key too often. Requiring digits means that many people will just "0" for "o" and "1" for "L".

So it's really easy to concoct passwords which you know are bad, because you know the methods used to select which passwords you'd consider; if the developers of the strength meter don't take your particular generation algorithm into account the meter will show the password to be stronger than you know it to be.

A fourth car races by.

It opens, and the words Top Gear: Mark II appear.

It's a young British woman of mixed Asian descent.

The crowd goes wild.

Seriously, an exotic woman driving exotic cars too fast? Who'd watch that?

I would, because I'm a man and I'm not afraid to admit that on some level I'm a pig. Ideally she'd be smart and funny too, because I don't like to think of myself as being a total pig, but either way I'm in.

Meanwhile, the BBC has a chance to reinvent Top Gear with younger presenters

Nailed it. It's like the old saw about the Chinese character for "crisis" being made up of characters for "danger" and "opportunity". No matter what happens now they're going to lose some of their long-term fans. But at some point young people aren't going to be so keen on watching some ancient codger behaving like an ass.

If they play this right it could become like Dr. Who, with a reboot every few years to bring in fresh blood.

Sure. But the man verbally abused and bullied a subordinate. Then he physically assaulted him -- or perhaps by that point the physical altercation was mutual.

At some point you have to ask yourself whether you have your priorities straight. As a fan of the show I'm sorry to the big ape gone. As a fan of civilized behavior I'm happy to see at least a minimum standard of decency in behavior getting enforced.

Are people really going to miss yet another totally fake show pretending to be reality? Is it just because this one combined cars and Daily Mail-style politics?

Sorry, but I have no sympathy for a primadonna for whom curses at an employee for 20 minutes and then physically assaults him up for half a minute (without any resistance from his victim) before someone pulled him off, all because the Clarkson's food wasn't warm. And this is hardly the first time Clarkson has behaved like this, he was already on "final warning" after a string of other incidents. What befalls him is his own bloody fault. And all of the abuse that the victim got over this whole thing... my favorite tweet on the subject was:

"Man assaults another man and victim receives abuse because people can’t watch a TV show about cars. Bravo society. "

Comment Most of Japan is very beautiful... (Score 4, Interesting) 197

.... but their beaches, usually not so much. So hopefully this won't be too much of an eyesore. Japan is usually pretty good about trying to fit human-made structures into the landscape; my friends and I had a running joke when we were there: "They have the prettiest drainage ditches here!" ;) That said, a 250-mile long, 4-story "anything", that's going to be hard to make look nice.

I'm rather curious about what kind of concrete they're going to use. Japan has been a pioneer in the use of fiber-reinforced concrete, I wonder if they'll use that in lieu of steel that may need cathodic protection in such a high salt environment?
