Reading between the lines here, it seems fairly probable that Truecrypt has either

a) Very serious security bugs, or
b) Had backdoors introduced by the NSA.(Does Truecrypt use elliptic curve cryptography?)

In either event the code is basically tainted and shouldn't be used for any future projects.

The vague and sometimes bizzare nature of the statements from the Truecrypt dev team, including this one, lead me to believe that they have been placed under a standard NSA gagging order and have decided to burn Truecrypt rather than see it be turned against its users. Comments like "Forking is Impossibe" appear to be an open code for communicating that they are essentially unable to communicate, but that Truecrypt is no longer a trustworthy piece of software.

Reading though the Lavabit case, it's clear that those placed under NSA gagging orders have very, very little room for legal/media maneuver, but nevertheless still retain the freedom to walk away from their projects and tell others not to use them. Such actions appear to be the last defense of cryptographers in the US, and I think that is what we're seeing with Truecrypt.

Launch the data into oputer space on a satellite, programmed to transmit the data after a set time period. For best results, send the machine on a massive period orbit to the outer solar system, or in a pinch, crash land it it on the Moon or Mars.

Governments will either have to give up, or else fund massive space project. Either way, we win.

Data Center With a Brain: Google Using Machine Learning In Server Farms 26

Google data center executive Joe Kava said the use of neural networks will allow Google to reach new frontiers in efficiency in its server farms, moving beyond what its engineers can see and analyze. Google's data centers aren't yet ready to drive themselves. But the new tools have been able to predict Google's data center performance with 99.96 percent accuracy."

Doing this in your head the traditional way would be hard.

I would not do it in my head. I would take out a pen and a piece of paper, and slowly work through the problem step by step until I had a final answer I was confident in. If the pen was in front of me, I'd probably finish faster than someone trying in their head, and I'd be guaranteed to be more accurate into the bargin.

Mental arithmetic should not be the goal of primary education, outside of the times tables. Children need to learn methods which reward care, patience and effort to find the final answer. This has benefits beyond the classroom.

A kid shouldn't be allowed out of sixth grade if they cannot quickly answer the following questions:

40 - 16
8 * 9
1/2 - 1/3

I must disagree here. Quick mental proficiency should not be the ultimate goal. (Times tables excepted)

What should be expected of a sixth grade student is that they be able to take out pen and paper, and carefully through systematic methods to obtain the correct answer. In addition to this, they should have enough sense of number to know whether the answer is reasonable.

Pen and paper proficiency should be preferred over all other mathematical skills in primary education. Students should feel confident in their own ability to, with patience and care, work out the answer themselves.

We all like praise, but a hike in our pay is the best kind of ways.
