No, but you will need the CS degree to be a good programmer. If you know what is going on under the hood you can avoid those O(N^5) operations that make your code inefficient. If you just blindly use whatever looks vaguely correct in the standard library you'll never know why your code is so slow.

Where I grew up, it was the same but the dick contest was with off road vehicles. The biggest, shiniest off road vehicle they could afford with the largest tires. They never went off road, but that wasn't the point.

SOME guys went off road - but their trucks looked like they had rolled over (and they had).

Most of us do have a need to transmit messages privately. Do you not make any online purchases?

Yes, but those have to use public-key encryption. I am sure of my one-time-pad encryption because it's just exclusive-OR with the data, and I am sure that my diode noise is really random and there is no way for anyone else to predict or duplicate it. I can not extend the same degree of surety to public-key encryption. The software is complex, the math is hard to understand, and it all depends on the assumption that some algorithms are difficult to reverse - which might not be true.

Only if there is some other device on the network that needs data 24/7. For most people the router is going to go mostly idle once the laptop is closed because there's nothing for it to be talking to. The only thing it should be transmitting is the occasional beacon.

The problem with FM static is that you could start receiving a station, and if you don't happen to realize you are now getting low-entropy data, that's a problem.

There are many well-characterized forms of electronic noise: thermal noise, shot noise, avalanche noise, flicker noise, all of these are easy to produce with parts that cost a few dollars.

Comment: Randomness can't come from a computer program (Score 2, Interesting) 64 64

True randomness comes from quantum mechanical phenomena. Linux /dev/random is chaotic, yes, enough to seed a software "R"NG. But we can do better and devices to do so are cheap these days.

I wouldn't trust anything but diode noise for randomness. If I had a need to transmit messages privately, I'd only trust a one-time pad.

Communism has been tried on a large scale - see Mao's Great Leap Forward.

Nope. That was a totalitarian socialist program pushing a collectivism that didn't work. Communism is a post-scarcity society and obviously scarcity was the thing Mao produced best.

Comment: It just makes the router worse. (Score 3, Informative) 207 207

The description makes it sound like they just cut the Tx power on the router by two thirds when you enable the mode, which means it will just have a much shorter range. Even better: This would only help if the woman stayed near the router, she's going to get a lot more "radiation" from her laptop, since it has a similar radio and of course is much closer to her. Even if the science were sound, this wouldn't work. It's both dumb and pointless.

I didn't actually work on GPUs very much at Pixar, the image computer I worked on was the grandfather of the SIMD image processing instructions on modern CPUs. What would become a GPU later on was a very expensive box from Silicon Graphics, I had one that cost at least a quarter Million dollars.

Excessive login or logout messages are a sure sign of senility.
