Comment: Re:Randomness can't come from a computer program (Score 1) 64 64

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.

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.

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.

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.

+ - ICANN seeks comment on limiting anonymized domain registration->

angry tapir writes: Privacy advocates are sounding the alarm over a potential policy change that would prevent some people from registering website addresses without revealing their personal information. ICANN, the regulatory body that oversees domain names, has asked for public comment on whether it should prohibit the private registration of domains which are "associated with commercial activities and which are used for online financial transactions."

+ - New Zealand ISPs back down on anti-geoblocking support->

angry tapir writes: A number of New Zealand Internet service providers will no longer offer their customers support for circumventing regional restrictions on accessing online video content. Major New Zealand media companies SKY, TVNZ, Lightbox and MediaWorks filed a lawsuit in April, arguing that skirting geoblocks violates the distribution rights of its media clients for the New Zealand market. The parties have reached an out-of-court settlement.

If they actually told us how to program their microengines, something good might come of it. But they'll probably just BSD-license a list of numbers, as others have.

I liked writing bit-slice microcode at Pixar. I really could get every last bit of power out of the hardware.

Maybe you should learn what communism is before calling anyone "commiefriend". (Which I have to say, is really repulsive. It's sort of like picking your nose over the internet.) I think you are discussing the difference between lasiez-faire ecomomics and regulated markets. Communism is a very great difference in scale from that. And it's never been tried on a national scale just as "free market" has never been tried because there are always economic biases that make it impossible. What there has been so far is socialism.

I think you're missing the fundamental economic issue that drives all of this. It's the provision of essentially infinite amounts of credit. This is done by government, not banks. Essentially all home loans come from Fannie Mae or Freddie Mac, banks and finance companies are really just front-ends for them and sell their loans to the government once financed.

Given infinite credit, any scarce but necessary resource is going to be bid to absurd values.

It is by no means being a hippie to assert that government should not distort the market for credit, and to expect that urban and suburban land values would return to more realistic rates once the distortion was removed. Too bad that lots of people have already invested in unrealistic land values. They would have to lose.

The program isn't debugged until the last user is dead.
