I agree. Plus, if you look at the syllabus of the course ConcernedStudent is concerned about (which is posted here) the rules are clear:
All work on quizzes, tests, design assignments, and labs sit to be wholly your own. Possessing, using, providing, or exchanging improperly acquired written, verbal or electronic information will be considered a violation of the academic honor code. Violations will result in a grade of F for the semester.
Ask yourself, if the assignment was to write a web browser that does x, y and z and you brought in the Mozilla source code, would you expect a good grade? No.
The professor may be a stickler, but he did lay things out in the syllabus.
By the way, I'm an occasional teaching assistant. What you really want to do if you aren't absolutely certain about the right thing to do is ask the TA or professor. They'll be glad to help you out.
I have a question. (And no, I'm not trying to be a wise guy.)
Lots of articles about quantum computers talk about how processing is done and how fast it will be.
How does quantum memory work?
Are mass/heat constraints a problem?
The reason I ask is that a while back there was some interest in using the properties of chemical reactions, specifically the polymerization of DNA, to solve NP-complete problems fast. This strategy was used to solve some easy travelling salesman problems, for example. It was quickly pointed out, however, that to solve hard problems was going to take too much DNA. That is, the DNA system was fine for solving travelling salesman with 5 nodes, but 100 nodes (or something) would take converting the entire mass of the universe into DNA, so DNA computers are a dead end.
Are there similar constraints with quantum computers? Why not?
If you like cool bots, check out the book Robo Sapiens. It has about fifty 2-3 page interviews with roboticists and tons of nice photos. It's mostly aimed at laymen, so don't get mad if it's not techie enough for you.
It's common knowledge that IBM provided service and leased equipment to the Nazis.
The real questions are less about whether IBM is evil than they are about worshipful attitudes toward American tycoons. Don't you think it's important that the leader of a major industry probably knowingly provided equipment for use in a mass murder? The fact that the victims were Jews is irrelevant.

For a while, lots of people were getting cease and decist letters from the CueCat people. Then they stopped. Hmmm, maybe they ran out of money to pay the lawyers! Does anyone know what happened?
I never got the letter, and I wrote these Java drivers for CueCat (Take them if you want. They're GPL'd):
Tilden's is one of the best interviews in the book
Robo sapiens. He's hilarious! The book is a series of one and two page interviews with a large (~50) number of researchers in different areas of robotics. The book is aimed at laypeople, so don't be disappointed if it's not techie enough for you. It's worth it for the awesome photographs. It gets four out of five stars at Amazon (9 reviews).
Get the Pitsco Catalog. It has tons of Lego stuff,
as well as do-it-yourself supplies.
You can make proximity detectors with the flex sensors sold by Pitsco. They're the same sensors as in the Nintendo Glove Controllers. For more info on homebrew Lego stuff go to Mike Gasperi's Homebrew Sensors page:
I wrote a set of decoder Java Classes that you can use if you want. They are designed to be incorporated into other programs, but they work standalone, too. Check out:
Why does Katz take it at face value that gaming makes you a smarter, more articulate team player and simultaneously reject out of hand the possibility that games can make you violent?
It seems like Katz's bias is really shining through, here. If Katz is admitting that games can have all of these positive effects, he has to admit they might have negative consequences, too -- something he would never concede.
This is the same kind of logic flaw that a lot of people run into in racist arguments. For example, lots of people think they are doing American Indians a favor by asserting that American Indians are naturally in touch with the land and with nature. But if they admit that, then they also have to admit that American Indians might naturally be lazy drunks.
If you look up at the right time, you can see Iridium satellites, even during the day, because they have big panels that reflect sunlight like a mirror. You just need to look up at the right time, in the right place.
The Heavens Above web site can tell you where to look.
If you plug in your latitude and longitude, or choose your location from a menu, the Heavens above calculator will tell you exactly where and when to look. It also tells you where to look to see the Space Shuttle and other cool stuff. One time I saw Mir + Space Shuttle connected together!
Except for the handful of things outlined by Zawinski, Java is great. You can even get good performance (though not even close to C-like) with native compilers.
In addition to pigments similar to the Red, Green, and Blue that people have, birds have a Violet absorbing pigment. Some birds can even see in the UV range.
In addition, the pigments have evolved this state in the long term, and the four pigments are very different from one another. The article about tetrochromat women says that their vision is probably the same as the rest of us except in extremely rare cases because the fourth pigment is almost identical to either the blue or the red pigment they already have.
This is similar to an earlier attempt.

Golden Rice
·
· Score: 1
A while back someone got the idea to spread specially bred corn around Africa. It was drought
tolerant, easy to share seeds and extra nutritious. The problem was, it didn't look and taste exactly like what people were used to, so they wouldn't eat it. The corn disappeared.
This is going to happen with "Golden" rice, too. People pay a lot of attention to taste, consistency and appearance. It's unlikely they'll eat Golden rice unless they're starving, and if they are starving they won't be able to afford to grow it anyway.
If yellow milk were more nutritious, would you drink it? Be honest.
The Lego Mindstorms systems are slick, but a major problem is that Lego hasn't been very forthcoming with information about how to write custom software for the system. I use Linux, so Lego's out of the box programming tools are useless.
Luckily, a lot of effort has gone into reverse engineering the Mindstorms Brick. Russell Nelson has a lot of good information at http://www.crynwr.com/lego-robotics/
I have been working on a Java toolkit for programming the Brick, and for manipulating it interactively. My kit, called RCXComm, can establish serial connections with the RCX brick via the IR port, and can handle packet communications, upload programs, send messages to active RCX Programs, as well as a few other things. The RCXComm classes can be used as standalone software, but they are really intended for incorporation into other applications.

Articles on quantum computing focus on processing speed.
But what about memory? If processing is fast but memory is low, the constraints on quantum computing will be different than if memory is high.
Consider Quake, for example. A fast processor isn't exciting unless it has the memory to handle sophisticated (i.e. high memory) maps.
How does quantum memory work? What are the constraints on it?
