The typical energy of a cosmic ray is around 300 MeV. Interestingly, around mid 1990's the feature size of SRAM cells got small enough that a 300 MeV event could flip the state. This means that the cache memory now needs ECC as well as main memory, but I don't see that happening in too many CPUs. Reference:
Some enterprise server systems use end-to-end protection, meaning the data block is longer. If you write 512 bytes of data + 12 bytes or so of check data and carry that through all of the layers, it can prevent the data corruption from going undiscovered. The check data usually includes the block's address, so that data written with correct CRC but in the wrong place will also be discovered. It is bad enough to have data corrupted by a hardware failure, much worse not to detect it.
Point 1 - you are correct. The software license can't give you any additional access to the hardware, and Tivo cannot prevent you from doing what you want with the hardware. Verizon just lost a lawsuit for trying to block people from unlocking their phones. What Tivo does not have to do is make hardware that lets you run your own software. That isn't their business.
Point 2 - less correct. Games are a free market because there are also games for PCs, which are relatively cheap game consoles. There is also a market for standalone games, like mechanical pinball machines, or Munchkin (highly recommended). People choose the game console games because it's the biggest bang for the buck. Metroid on Wii rocks. I don't think that it is abuse that in order for me to piggyback my game on the hard work of the Wii developers, that they (or their stockholders) get a cut.
They have also left out the One Time Pad system - still unbreakable.
I will be passing all my public keys through two slits and keeping one of them under observation at all times from now on. That should keep me safe from quantum computers.
"Suppose a company begins advertising Linux desktop computers locked to their internet provider service, and heavily discounted. Many, many people will buy them, not really understanding the negatives: If they find their service is terrible, they cannot switch to another ISP without paying a huge penalty that is hidden in the fine print of their contract."
This is almost exactly the way that the cell phone market works. Cell phone service providers buy phones in volume and sell them locked to their service as part of the contract. If you had to pay the full price for your cell phone, then not as many people would have cell phones today.
However, the real issue is: should a software license control what you can do with the hardware? Tivo provides the source for all of their changes. Nothing prevents you from designing your own DVR and using Tivo's code on hardware that is not locked. Nobody has done this, and MythTV hasn't wiped out Tivo, because the model of selling the hardware at low cost and making money on service is desireable. People want cell phones with a service contract. People want to lease cars rather than pay the full price up front. People want a low cost game console that only plays high-priced games. The market shows this.
Looking over my website hits, it looks like 70% IE, 27% Mozilla, 0.3% Opera, a few Nokia or Blackberry and the rest is spiders. What does Safari identify as? I'm not seeing it at all in 30,000 hits.
"No risk of data corruption if you forget to charge it or otherwise let the battery run low, eh?" Seagate DAVE is conventional rotating disk, it's not volatile storage. Circuitry for shutting off writes during power-up and power-down is standard on hard disks and flash drives.
For a laptop drive replacement, drop cycles are just as important as erase/write cycles. After a few drops a laptop harddrive starts going "eeeeeeeeek eeeeeeeeeeek eeeeeeeeek" whereas I hear no sound coming from the flash drive.
"What else do the police do, other than protecting my person and property?"
Police should investigate crimes against your person and property after they have occurred. If you want the police to protect you from crime then you should be in favor of the Patriot Act and opposed to personal privacy or liberty. Please stand still while we insert the RFID chip to monitor you.
sci.math.num-analysis might be more focused on this type of problem than sci.math and has fewer kooks. Search on google gives 148 hits for "wave equation" in that group.
5) Now prove that the recipient doesn't have legal rights to perform the download, (like a signed letter from the copyright owner), or are you police, judge, jury and hangman?
So you want to send 200 people a file. We each FTP from you at 256k x 1. Or we BT and all get it simultaneously from each other at 256K x 100. Trying hard to see your logic. BT wins hands down.

Clean Air Act provides the mentioned penalties for vehicles sold without "a certificate of conformity". So I assume that these vehicles are only legal under California's experimental "pilot test program" and have not been certified. Seeing the actual Volvo memo might answer this, of course.
Its a complex issue. Fertilizer feeds algae which then grows on and kills coral. Fishing reduces populations needed for healthy reefs. Murky water and dirt landing on the coral block sunlight. Water temperature affects density, currents, and salinity so it isn't just the direct effect of what the coral like. There are many factors, but the main thing it comes down to is that researchers can get to spend time diving in the Bahamas.

Just to be on the safe side, you should probably change your name.

Then save options to make it permanent. Why? Are you still using some emacs variant from 1970?

This is just the same as the way broadcast television took over and drove the original cable TV out of business. Oh, wait...

int random()
i++;
Every value of i is equally represented. Must be a perfect random number generator.
There are security updates to cat?

I once timed the install at 12 seconds. Highly recommended.

Taxpayers funded the telecom infrastructure? News to me. I always thought it was the dot-com boom investors in the period '95 - 00.

My local library has the DVDs so that seems to be the best of all possible worlds - free, good quality, no ads.
