Do a search someday on " Information Wars 2025, Air Force". The information is not always for machines. Our soldiers will have protection from nervous system interference. While the 'terrorists' will hear, feel, and see, etc what ever we project onto them. Ever notice how the Slashdot war helmet resembles the tin-foil hat?

You are correct, Americans are intentionally kept ignorant. Tea bags bring us back to the halcyon days of tarring and feathering. Most Americans barely understand a Watt. So a lumen, etc are beyond the goal of conformist society.

I, for one welcome our new fluorescent and LED masters.

I, for one welcome our new quantum overlords.

FLOPS / Watt is the future. No doubt. Tesla (NVIDIA) has the edge on the low end now. Low power per cycle will win in the long term. Multi core x64 bit for now. But to the powers that be, 32 / 64 /128 bits per watt per cycle will rule someday.

They skipped IP V5, so why not skip V6? IP V7, although alpha is more likely to be adapted than IP V3, or V5. Skipping generations seems the historical precedence. Probably the military had an IP V5, and V3 for internal use that was very secure, and DARPA funds less secure information for us.

Supreme Commander (http://en.wikipedia.org/wiki/Supreme_Commander) is a great game for MMO. Already large scale, and scalable.

Most of these games are good, and run on linux:

I have played "The Battle for Wesnoth", that is very good for turn based strategy.

Orange book:

A-
You are are a single communication construct. No one outside the circle of trust has any idea what is communicated.

B-
You are in a network (circle) of trust. moving data to each other is logged, and allowed/censored.

C-
A typical LAN with verifiable security.

D-
The internet, a net work of networks. Data can 'vanish', as a function of time/money spent on keeping the data stored.

Read the data security handbook summarized:

Ignorance is strength,
War is peace,
Freedom is slavery.

The post about OS-X, is both a "flame-bait", and a noteworthy, free speech comment. Often when moderating and I read such a post, I will use "interesting" which does not penalize the remarkable comment. It would be nice to have the option to mark the post as "flame-bait" but not subtract rating points. "Off-topic" has the same problem.

FYI
The reason the Babylonians, and the Egyptians, and we use 360 degrees is this:

355/113 = 3.14159292035
pi `= 3.14159265359

A difference of 8.5x10-6%

Which makes 355/113 close enough to pi. 360 is close to 355 which is why we use 360 degrees for angles and time.

Pumping air is also much worse than pushing water around. Air is a compressible fluid, while water is practically incompressible. Extra energy is wasted at the pressure source (AC), and at the exit, as the air changes volume.

A similar effect from the "canned air" that turns cold when uncompressed. Unless you are pushing that air over your skin while sweating in hot weather, the energy is pure extra waste. You cannot make a can of "compressed water", because it is not compressible.

All IBM is saying is that water is a better heat conductor, and air is an insulator.

http://en.wikipedia.org/wiki/Specific_heat_capacity

Water ; 4 J /cm^3 K
Air ; 0.001 J /cm^3 K

Water/Air = 4000 times more heat transfer.

So, given the choice, you would use water to transfer heat.
