Comment Re:Very cool! (Score 2) 28

SSL is a protocol for agreeing on a set of encryption parameters to use (which cipher, what keys, and so on) rather than a cipher itself. The two most common ciphers, (3)DES and AES (as well as all the other block ciphers I know of) produce a ciphertext that's the same size as the plaintext (plus padding if necessary to fill out the block size). An SSL connection, however, frequently gzips the content before running it through the cipher, so the size of the ciphertext depends on the compressibility of the plaintext.

This is essentially what's happening here; PNG is a bitmap form, but it is supports a couple of different types of compression, so tiles of the same pixel dimensions compress to different file sizes, which can be distinguished even without knowing the contents.

That's nonsense. "Society" is just a term for the collection of lots of people, and "society" has no goals of its own; each of the people has individual goals, some of which mostly align (e.g., most people are better off during peacetime than during war) and some of which vary widely (e.g., musical taste). Similarly, "the market" is just the collection of lots of individuals' economic activity, and the people making up the market most certainly do plan for the future; this is why commodity prices spike instantly on news of some catastrophe.

The claim that "$foo is running out, so you must give me power to keep you from using $foo" has been made repeatedly throughout history and has fallen flat every time. When it comes to oil specifically, the proven reserves of oil are greater now than they ever have been before. If oil were running out, the price of oil would have risen sharply, and that market you dismiss would have created incentives not only for people to use less but also for the limited oil to go to its most valued use.

Additionally, the Thrive has two power quirks that I appreciate: Its battery is easily replaceable, and it sacrifices the ability to charge via USB for a 30W power supply that can charge its battery from zero to full in 90 minutes. For typical business use, I only need to charge it about 30 minutes daily.

Comment Re:Voluntary self-regulation works. (Score 1) 75

"Too big to fail" is utter nonsense. Make it clear that no business is going to get bailed out, and then let the failures fail.

Regulators always end up working more for the regulated industries than the public at large; it's known as regulatory capture and is a predictable result of the fact that the regulated industries spend lots of time lobbying the regulators on the specific issues while the public at large is too busy paying attention to Charlie Sheen.
