How did you find the entropy of these passwords? By my calculations 8 random characters from a set of 62 is 47.6 bits, not 36. (log(2,62)* 8 = 47.6) On a logarithmic scale, this is a huge difference. For the passphrase, 30 characters chosen

PBKDF2 is a key strengthening algorithm, used to generate a key from a shared secret. AES is a block cipher. I'm not a security expert, but simply padding out the password to the right number of bits seems like a huge no-no. Instead, you sh

I was able to reproduce the crash once by adding a bookmark, which probably forces a sync. Gmail came back up for me, though, so I'm not able to test this again.

Not only is it anecdotal, these sorts of discussions seem to bring all the outliers out of the woodwork. There are always going to be some people who have many bad experiences with a company, even if overall reliability is good. Here is the

Regarding the claim that you can train yourself to sleep less, you might find this study interesting: http://www.nytimes.com/2011/04/17/magazine/mag-17Sleep-t.htm... They had three different groups that could sleep either 4, 6 or 8 hours.

Well, it's a joke in the sense that I did it for fun and not because I think people will actually start using it. :) You're right about the sunrise, though. To solve this, I say that, by convention, 6AM is sunrise no matter your location. T

Someone could fraudulently initiate a draft, but ACH drafts can be chargedback, giving you some protection. Obviously this is trickier and more painful than a credit card chargeback because it's your money that's been taken, and not your CC

The only banking details it needs are you routing and account number. Granted, you shouldn't give those out to just anyone, but it's the same info you give out every time you write a check. If you wanted to be really paranoid, you could set

You're absolutely right! :) It would be interesting if someone could extend this to look at how different color representations affect the results, such as using HSL rather than RGB. I tried to factor out the getSuccessors function and eval

I selected "MacBook" for my MB Air, and it worked, which is weird because I don't think they make plain MacBooks anymore. They also ask for the address of the reseller, but I purchased mine from Amazon, so I just entered my address.

I think part of what might be going on here is that OOP patterns incur a large upfront cost in complexity, but the hope is that it will payoff later when it comes to maintaining and extending the code. For example, the visitor pattern he ta
