While the preemptible kernel is a more elegant solution to scheduling latency than peppering the kernel with rescheduling checks, Andrew Morton's "Low Latency" patches give better performance. I'm doing 24-bit/96-kHz audio and with the LL kernel I get vastly more stable performance than the PE kernel. Note that you aren't going to see a spit of difference with either kernel unless the process is running at realtime priority (i.e. SCHED_FIFO or SCHED_RR).
Freenet has lots of unecessary complexity from trying to provide both publisher and downloader untraceability. Why take huge performance hits for hosting legal data like the linux kernel? Also, Freenet looses because it requires people to leave their Freenet node running after they are done dowloading, else they aren't really helping to relieve the main problem here. It turns out that the vast majority of people don't want to do this; they just want to get what they want and get the hell out.
p2p systems like the one you mention use cryptographic hashes to make sure you are getting the file you really wanted. It would be just as secure as downloading from kernel.org.
The Linux Kernel and other open source projects should use some of the up and coming peer-to-peer distribution technology to host files. Tools like BitTorrent use the bandwidth of the current downloaders to relieve pressure on the main publishers. DL'ers get pieces of the file in random order and automatically exchange pieces with each other. From the users perspective, they just clicked a link. This technology desperately needs to be used by the Kernel archives, Debian, RedCarpet, etc...

If I buy and download an eBook, I have no physical copy . With no physical copy, the distribution right has not been exhausted, and I have no First Sale right. The act of "giving" my eBook to someone else is thus illegal, since I don't have a physical copy to give.
Unfortunatley, your predicate that there is no physical copy is wrong. The copy on your hard drive is certainly a physical copy for the purposes of copyright law ("fixed in a tangeable medium.") Namely, the work is fixed in the magnetic particles on the drive platter. Even the copy in RAM while executing/viewing the work is physical copy! For this case, the law specifically allows copies to be made that are necessary to utilize an authorized copy.
You are right though, that there is no law or precident for supporting the secondary market when authorized copies are made directly onto a general-purpose storage device owned by the consumer, where transferring ownership of the device is not feasable.
Back near the turn of the last century, book publishers printed contracts on their books, limiting the ability of the customer to resell or lend his purchases. This practice was halted by the US Supreme court and the consumers right to do what they wish with legitimately purchased copies (with certain limited exceptions) was eventually codified in the US code as part of the '76 Copyright Act.
Given that software is a work of authorship protected by Copyright law, how is it that software publishers get away with these old tricks of printing restrictive contracts on their works, claiming assent simply by using the software, denying people their rights under Copyright law?
Unfortunately, information about what the smart card is doing is leaked through the power supply. Giving the smartcard it's own internal power supply can help prevent power analysis attacks from the reader itself. By eliminating an input/output, the black box of the smart card can be made that much "blacker."

are you kidding? The prosecutor most likely DID threaten a felony charge using trumped up software value and offered the misdemeanor charge as a plea bargain. Given the choice of financial ruin, even if you win, and the prospect of a felony conviction (almost certain in this case), OR plea to a misdemeanor and get probation and community service, almost everyone would take the plea bargain. It's easier on everone, even if it's not necessarily "just."

My 25mhz 68040-based NeXTstation Color does alpha channel transparency just fine, thank you. There is something else about Mac OSX that makes it so slow. fwiw, the current release is very much still beta quality and X.1 is supposed to be quite a bit more optimized.
I've been using the ProPoint mouse and it requires zero wrist movement to operate. You can hold it in any position that is comfortable and it works just as well with either hand. The only problem is that it's ps/2 so you need an adapter to get it to work on a computer that lacks vestigial ports.
Combine with a pair of one-handed keyboards like the BAT and you are well on your way to increased productivity with vastly lower stress on your wrists and arms.
Good lord, folks, it's 2001 so why are we still putting semicolons at the end of every line?? Parsers have come a long way in thirty years. It turns out that terminating a line with anything more than a carriage return is completely unnecessary.
I recently had to demo a port of our software to Mac OS X for a little gathering of Mac and Apple people. Of course I only got it working the night before. Just as I was about to pull the cables out of my laptop and head to the demo I did a little CVS updating and some copying of files.
When I started setting up on stage I realized that I had blown away all the changes I made to one critical file (the app is in Python and doesn't have a single compiled binary.) Instead of going through my well rehearsed talk I had to re do the changes up at the podium while my colleagues stammered through an impromptu presentation.
I got it working in time and was able to give a cool demo! Talk about stress though. Good thing I wasn't demoing for investors.
The way the law works, the Electronics Communications Privacy Act and famous precident such as Epson, neither your employer nor anyone else can go through your stored communications if you have a reasonable expectation that they are private. The deal is that pretty much every company has an explicit policy stating that you should have no expectation of privacy on their computing equipment. They have lawyers that tell them to do this because of laws such as ECPA
If you don't like it then get your company to change it's policies. By and large most companies don't tap their employees phones because the management would never want their own phones tapped. However, it's easy to spot an employee who is abusing the phone equiment (they are constantly chit-chatting). With computers it's easy to divert them to your own benefit without others easily noticing. For this reason I wouldn't expect companies to change their policies any time soon.
No, that would in fact make you a criminal because the language of the law is "import, offer to the public, provide, and otherwise traffic in"... it says nothing about the distribution being commercial or not. Professor Felten wasn't going to sell his paper, he just wanted to present it at a conference.
The only reason taking money is an issue in this case is because Elcomsoft used a USA based order processing company to accept payment for the software. This was necessary for the FBI to claim jurisdiction. If the order processor had been based in a country outside the USA then it would have been outside of the FBI's jurisdiction and there would not have been an arrest.
...except that cameras, like everything else electronic, are getting smaller all the time. Sure, most of the cameras on the street are large and obvious (because large cameras are cheap), but it won't be long before tiny cameras are cost effective for local governments. With modern image correction you don't even need a large lense to get decent quality. All that needs to be exposed is the end of a fiber optic cable. It's hard to counter a camera that you can't even see.
The justification offered by the recording industry is that CD's are both higher fidelity and longer lasting than tapes. Since you are getting a better quality product that does not deteriorate with use they feel justified in charging higher prices. Also, people keep buying CD's at the current prices in greater numbers every year so what incentive has the industry had to lower prices (FTC anti-trust rulings aside)?
Whatever. DAT didn't die because of the copy protection. MiniDisc has the same copy protection and is even worse for piracy than DAT (due to serial compression lossage) yet it sells like gangbusters by comparison. No, DAT died because it was an inconvenient tape based format. Consumers want random track access. Consumers hate rewinding tapes. Only pros and live concert tapers needed digital recording badly enough to suffer through digital tape.
Finally, there is a mathematical procedure that is claimed to work out a secure key by a _long_ process of exchanged messages and intensive calculation.
I suggest you get a book on cryptography, such as _Applied_Cryptography_ by Bruce Schnier. There are many key negotiation protocols, but the most famous is "Diffie-Hellman Key Exchange" which is also the first public key algorithm invented. It is actually quite simple and only takes one round trip of messages (Ian Goldberg came up with a protocol for doing DH key exchange over e-mail.) You start with a Generator, G, and a public key, n. Neither of these are secret. Alice and bob each generate a large nonce, x and y respectively, and do the following:
alice sends to bob X = G ^ x mod n
bob sends to alice Y = G ^ y mod n
shared secret is G ^ xy mod n which alice gets by computing Y ^ x mod n and bob gets by computing X ^ y mod n
alice and bob can each generate the secret key because they know either x or y. eve, an evesdropper, cannot generate the secret key because without either x or y, computing the secret key from X and Y alone requires calculating a discrete logarithm, which is a Hard Problem.
This is not intensive calculation by today's standards since my Java ring is powerful enough to do modular exponentiation in a reasonable amount of time, and it is several years old. You are absolutely correct that adding two way communication to a wireless keyboard/mouse would be much more expensive, however.
No, actually, Van Eck sniffing is NOT "easy." It takes thousands of dollars' worth of exotic equipment, and is nowhere near as foolproof as the media suggests.
I must say that this is not at all true. I've seen a demonstration of the recovery of the video signal from a Commodore PET from a few feet away using nothing more than an old portable B&W TV set (the ones that are about the size of a shoebox) and a simple amplifier inserted between the TV and the attenna. This was at HoHoCon '92. Sure, a PET is quite noisy, the distance was short, and the refresh rates weren't matched, but you could read the computer screen on the TV so it was a powerful demonstration nonetheless. Better equipment and analysis software does improve the effective range of recovery and allows recovery of signals that are more complex than video, but it goes to show that basic techniques are actually quite simple.
(And how many servers display passwords on the screen when you log onto them?)
At the aforementioned demonstration the presenter, Jim Carter, made it quite clear that it was possible to recover emissions from much more than the video circuitry. Disk controllers, network interfaces, keyboards; pretty much any circuit at all will generate emissions that can be recovered. Bootleg also stressed that information can be recovered from more than just the air. Information goes out through your electrical circuits too, this is why extremely secure facilities generate their own power and do not connect to the grid. Amazingly enough, the pipes in building sprinkler systems act as antennas and information can be recovered from the plumbing exiting the building. Information can even be recovered from the ground!
