Gah. Gravity is the second medium. Ok, you can tack on the solar wind. Unfortunately, you'll only be able to apply a limited amount of the thrust to perpendicular acceleration, because as the sail angles over, it will intersect with fewer particles. Figuring out the optimum angle would require more calculus than I want to do right now (which is none). 45 degrees is probably not it.
This is what happens when I go all monomaniacal on a project; I don't put enough thought into anything else.
This is neither a carnot engine nor a perpetual motion machine. This is where the article fails.
(hah, remembered paragraph breaks!) A solar sail converts free energy (kinetic energy of photons) into another kind of free energy (kinetic energy of the sail). Any heat exchange is an inefficiency in the system, not a necessary part of the process. This is comparable to pushing a box across the floor; neglecting friction, you could continue accelerating the box until the box matched your top speed (equivalent to the sail approaching light speed and no longer being struck by photons).
Another way to look at it is, the Carnot cycle applies in the engine of your car, because that is a heat engine (converts heat to kinetic energy). It does not apply in the transmission, because that is converting kinetic energy to a different kind of kinetic energy.
The same way sailing ships move against the wind... A zig-zag course, called tacking.
Umm, tacking only works because there are two media; the water and the wind. A aerodynamic shape (sail) uses the wind to create a thrust vector in the direction the wind is blowing. A hydrodynamic shape (the hull) uses the water to create a thrust vector perpendicular to the keel pointing in the general direction the wind is coming from. Add these together and you end up with a vector that points parallel to the keel, either forward or backward.
In free space you only have one medium, the solar wind. This is like a balloon rather than a ship, and the solar sail (like a balloon) will go the direction the wind is blowing no matter how it is aligned to it. It is possible to get a perpendicular (to the wind) vector component based on what direction you deflect the solar wind, but without a second medium to interact with you cannot get a negative parallel component.
"they will work, just not at USB2.0 speeds?"
Depends on the product. Imagine a CD burner that buffer underruns because the port's not fast enough.
I don't know if that actually happens, but a 40x difference in bandwidth makes it hard to degrade gracefully.
Nope. Most USB2 stuff won't work with USB1.1. It's possible that some USB2 peripherals are actually 1.1. If it expects the increased data rate that 2 provides, then the 1.1 hub will tell the device something along the lines of "What you talkin' 'bout, Willis?" and your device won't work.
Silverman said warrants must clearly define what police are looking for, otherwise searching through the other information could be invasion of privacy.
"Computers are very personal things," food industry management junior Russell Enfield said. "There's a lot of information on there."
But Ingham County Prosecutor Stuart Dunnings III said if police find any other evidence of crimes on the computer hard drive, they can be held against that person.
"It's the same thing as being pulled over for speeding and finding a gun on the front seat," Dunnings said.
So, I freely give them the pictures I took. While they are rummaging around they find my records for the side business I'm running, and my income tax records for the year. They realize I didn't claim the income from my side business on my income tax, and I get a nice visit from J. Random Suit from the IRS. All because I was helpful and complied with a request from the police department.
Huh. And they wonder why no one trusts public authority figures any more.
It's not "the same thing as being pulled over for speeding and finding a gun on the front seat", it's the same thing as being pulled over and having the police officer search your car. Something equivalent to the "gun in the front seat" analogy would be if the cops showed up, you let them in and handed them the hard drive, and in the process they saw the dead body of the mailman you murdered lying on the living room floor.
In this student's situation, my answer would have been "No, you can't have the hard drive. But if you want to come back in a couple hours, I'll have copies of those photos burned to a CD and you can have that." Multiple copies, even, if they want them. Heck, if they've got a place they want me to drop those CDs off at rather than coming by again, I'll do it. I'm perfecly willing to provide help with an investigation if I can; I'm just not willing to potentially lose an 80G hard drive or potentially incriminate myself in the process.
I'm unfamiliar with your "Computer Misuse Act". However, if you can prove their update damaged your modem, my completely unprofessional opinion is that it falls under whatever "hacking" laws you have. They accessed your hardware without your permission. Then they damaged it. They should be responsible for replacement of the hardware in the same way that someone who runs a stop sign and totals your car is responsible for replacement of the car. Laws don't (well, shouldn't) just protect companies; they also protect the individual.
Trouble is: your average P2P user doesn't have a copy of the CD or DVD to match up to the movie or music they have downloaded. If this is so they are in violation of the law for infringing on copyright.
Granted. But, it's a far cry from "average" to "every".
People like you, who can't seem to understand why they should be charged as a criminal for committing criminal acts.
As opposed to people like you, who assume people like me are guilty without any evidence?
No, he's referring to the people that seem to think it's their God-given right to steal copyrighted information, in whatever form it may be.
It is, however, my owner-given right to download copyrighted information that the owner has given permission to let me download. It is also my Constitution-given right to be assumed innocent until proven guilty. Not the other way around.
Ok, here's an example of why. Take J.Random interstate loop in a big city. 90% of people driving on that loop speed. There's no way for the cops to pull over every speeding car, so instead they shut down the highway in order to prevent the illegal activity. From that perspective, it sounds perfectly reasonable, but now you have all that traffic taking surface streets rather than the highway, creating congestion and inconvenience for far more people than the ones that were using the highway.
Conceptually, the idea is similar to the Prohibition in the US back when (Alcohol is evil, anyone who drinks alcohol is evil, so we'll ban alcohol so nobody is evil).
People get drunk and do stupid things, things that are dangerous to them and people around them. Just like file traders download illegal songs all day and cut into the profits of media companies.
Yes, P2P networks can be used for illegal purposes. So can just about anything. However, just like, say, guns, if p2p becomes illegal then the illegal activities won't stop, but the people putting that tool to good use will have to make do with something else.
Probably because when you search places like Kazaa, the chances of finding any software, images or music that isn't copyrighted is extremely low.
And, of course, whether that copyrighted software, images or music has been released by the copyright owners for trading has no bearing on whether it's legal or not to download it. Freeware, anyone?
Well, if you really want to be pedantic about this, you also are wrong. The sum of the three angles must be greater than n*360+180 and less than (n+1)*360, n being any real integer. It was never specified that the three left angles had to be the same value; a 180 degree left followed by two 1 degree lefts are valid, but counter to your statement.
I didn't see anyone else make this comment yet. It is not your responsibility to make sure I don't cheat; rather it is my responsibility to make sure I don't cheat. The idea that you could be responsible for another student stealing your work is just as inane as if you were driving through an intersection, someone else ran a stop sign and hit you, and you got the ticket because you were in the way.
This is the important issue here. There is a fine line between plagarism and reference, and it's the responsibility of the instructor and student to respect that line. If that responsibility falls on anyone else, then things get ridiculous.
You can use this example on them, for which the answer is obvious. I go to the library, grab someone's thesis on some random topic, and turn it in as a research paper of my own. Common sense dictates that I'm in error, and I'm in trouble. But using the logic you've been given, the library is at fault for putting that thesis in a place I could access. If it weren't available, I couldn't have copied it.
Where the hell did they get that 300,000,000 from? Did they send a knowlegable person into a reasonable statistical sampling of the world's gasoline stations, compile lists of pirated songs, and present the evidence? Or did Hilary stop into a gas station on the way back from Vegas and notice a bunch of CDs she could not recognize? Sorry, I don't buy the number or RIAA's ability to distinguish between a legitimate CD, from India for example, and a "pirate."
Someone else already answered that. It's something like $10k in lost revenue, and $299,990k in expenses for advertising, lobbying, and tracking down online music sharing. Those expenses are part of the "cost" of piracy, because if there were no piracy, they'd not have to spend that money.
Actually, I believe the point is that it is right now 2002, and in either 2 or 6 years someone other than Bush will be in office. He's on year 2 of a 4 year term.
This ridiculous idea ranks right up there with outlawing cash because the terrorists might mug us and take our wallets. "Once you're on the network, it doesn't matter where you got in," huh? So let's outlaw AOL, anyone can stick an AOL cd in their computer and get internet access.
Terrorists are the real-world equivalent of trolls, and every time we make a rediculous, reactionary lawto try to stop them, they just laugh that much harder.
Go find the Gutenberg Project and find a copy of "The Hacker Crackdown". In it is a description of a poorly written patch to telephone network control software back in the 70s(?) that brought down the telephone system for most of New York State. The failure was initially blamed on hackers, and the author considers it to be one of the major contributors to law enforcement's crackdown on hackers in the late 70s / early 80s (thus Hacker Crackdown).
Saying this will probably cause people to hunt me down and kill me, but the BSOD in the current windows driver model is actually a windows function. If a driver gets an exception it can't handle, it passes it down the stack. If it reaches the bottom of the stack, BSOD. Doesn't mean anything is actually wrong, just means that the idiot writing the driver didn't properly set up a function table.
Actually, I remember seeing something a while back about many insects _not_ using a tripod gait. All I remember specifically was cockroaches, which ran only on their hindmost legs.
Possibly, the driver was manually controlling one leg at at time, as opposed to letting the control software move three legs at a time. Direct control would allow the driver to ensure that each leg was in a solid footing before letting the vehicle weight shift to it.
