Slip on my part, but it still applies to diffraction. The interference pattern you will get on the opposite side of a grating will still be dependant on the frequency of light passing through it. It's just independant of the type of material used to form the grating.
Thanks for the catch though.
It's a nice trick. Diffraction to take advantage of the fact different wavelengths bend different amounts through the same material.
As usual, when someone says something can never be done, they've probably missed a good half of the equation.
I don't think that the security risk here is a digital one. It sounds more like te fact that you have un-monitorable, un-obstructed communication that is also untraceable and indistiguishable from generic traffic without significant effort. Insert the 9/11 big brother freaks who are obsessed with watching every move anyone makes and you'll start seeing laws against software coded in that fashion.

There's one reasonably significant problem with game dev.
With the exception of flash games, which seem reasonably difficult to code maliciously, any form of executable distributed by a site would reflect back on the owners of the site if it caused any problems. This means that people might have to take responsibility for their user's actions, which is unacceptable in any business model. Why should a company pay damages when a machine is trashed by a piece of malicious code that should have been a game.

Do you think all the parts are available at Digikey?

So, should we start pushing dev info be released publicly for all major systems? I'm sure sony would love to know if people out there would be interested in deving for the PS3...
From the sound of everyone's argument, the benefits of an interpreted language can be completely matched by a well coded kernel library of higher level functions.
There is no point to interpreting a language if the same functionality is already available in native code. Since the hardware within a given machine is fixed, converting an interpreted byte code into the native with an AOT compiler seems to be the most sensible use for interpreted code. It should be done once on install.
This is the modern CISC/RISC argument, in which people want to have all the functionality of a high level language without any of the complex code in the base. Interpreted code does not run faster than native, and the use of hybrid code supports that statement. Comparing how something like DirectX or OpenGL handles in java to C++ or C is not a valid comparison. It's two batches of native code.
The fact that garbage collection seems to be more efficient than sporatic cleanups makes sense, and should probably be considered when writing in a compiled language. Some variant on smart pointers would allow that principle to be used in C or C++
The arguments for an interpreted language can all be covered by a high level API in a native language. Why waste clock cycles interpreting every single add. It just slows down the system, and while the individual program may have no problem running, the overhead causes plenty of annoyance when you try to run 3 or 4 moderate programs at a time.
The only saving graces for interpreted languages are they tend to have a significant codebase to start from, and the same (compiled to byte code or raw) code will run on any supporting platform. This means anyone writing in java has a standard pattern to work from, and if they code well, anyone with experience in java can understand the code relatively easily.
If a compiled language started with a significant common api that was guaranteed to perform consistantly on various platforms, the 'problems' posed by them would be a moot point. This is why libraries like MING and SDL exist. They are an attempt to solve this. The major issue is they're being written for languages with such an extensive swamp of code that the odds of a standard surfacing are slim to none.
If your native code is running as slow as interpreted, I would really recommend getting that looked at. It would seem that people are losing the ability to write clean code since the crutch of interpreted languages is hiding so much of the finer grains of computer science. Sure, if you're writing apps that are fine slow, interpreted doesn't matter. If you're writing higher end programs like games, I would recommend cross-platform libraries in a native language. I'm currently working on learning SDL in C/C++ for exactly that reason.
Which brings up an interesting question of mine,
At what point is the stuff asked for by an EULA still legal
I understand we've got viral licensing etc at this point, so
you can say someone MUST use the same license for derivative products,
You can say someone can create with the software you have written, but they don't own it
Since it's a legally binding contract, what's to stop someone from saying "By agreeing to this, you also agree to leave me your full inheritance. You also relinquish the right to change your inheritance after this date.
Is there a legal limit?
Radio shack only sells cellphones now.

I have a retraction to make from my post regarding spin direction. It's not unheard of, but apparently, I'm wrong on this one.
"The Nintendo GameCube uses a unique storage medium, the GameCube Optical Disc, a proprietary format based on Matsushita's optical-disc technology; the discs are approximately 8 centimeters (3 1/8 inches) in diameter (considerably smaller than the 12 cm CDs or DVDs used in competitors' consoles), and the discs have a capacity of approximately 1.5 gigabytes. Contrary to popular belief, GameCube discs are not physically read any differently from a standard DVD disc, but are encrypted and contain a 'barcode' unreadable by most DVD drives. This move was mainly intended to prevent piracy of GCN titles, but like most anti-piracy technology, it was eventually cracked. By exploiting a flaw in Phantasy Star Online Episode I & II, users were able to connect their GameCubes to their PCs and run homebrew programming on the console. [3]. Later, a special debug mode in the GameCube drive was discovered which allowed the console to read and play from standard mini DVD-Rs." http://en.wikipedia.org/wiki/Nintendo_GameCube
The better question is, Will we be able to create the conditions that led to the creation of the univers in an Earth-based laboratory without killing ourselves! I certainly hope so. Cheap clean energy is a good thing.
I actually think it's very likely. Unlike sony and msoft, nintendo is not marketing a high-spec machine for the gear heads. They're focused on delivering games, and go to great lengths to make sure that their box is used ONLY for games. Ever notice that the cds spin backwards in a gamecube? Can you play music on a gamecube? They're selling a platform for gaming, and have successfully been doing exactly that for over 20 years. Most gamers don't even consider $400 dollars for a system. Remember the Sega Saturn? A system that was broadcast for specs with a $400 price tag. Do we still have sega consoles? I think 90% of consumers will end up getting the Wii simply because it hits their price range first. I don't personally get new systems till they drop below $150, I don't think Msoft or Sony will hit that mark any time soon. Until then, nintendo has a virtual monopoly on my console game purchases.
I'm just imagining the scenario where people are breaking into their own computer to get the tokens out. So what happens when you run out and it's ten minutes before a test solution needs to be posted online. This just sounds like an even less reliable computing method, all costs barred. I'm sure if someone in the US is creative enough, they can find people willing to GIVE them a pc of moderate quality.
For developing countries, as a means of bringing this to the market, yeah maybe, but it makes sense why it doesn't make sense in the US.
You might consider taking a two step approach. Open up with programming in VIM or emacs. Vim's syntax isn't too hard to pick up. Then switch to something like eclipse half way through the semester. Assuming they're expecting the change (mention it in a syllabus), there shouldn't be any issues. Also, knowing modern IDEs like Visual Studio or eclipse seem to be valuable on a resume. An added bonus.

I don't know. Would be interesting to see how this pans out.
So what if the XM radio companies sued the RIAA for frivility. I mean, sure we can all banter on about how absurd they are, but what if a company actually took a whack at it. For some reason, corporate lawsuits seem to drive this country's legal system. I have to wonder if they'd make the point we've been screaming ourselves hoarse over.
Interesting how you put that AC. If it's not an art to invent, why does it seem so hard for people to be able to. The same basic elements of inspiration and an understanding of your media are necessary. Sure, a lot of compscis are USED like builders, but to develop something new isn't like the builders you mentioned, so much as the designer or architect creating the idea. Also, any true coder knows what an art it is to debug efficiently. On that level, I'm sure there are parallels to your builders.
Exactly. And it's important to remember that it's possible to drive up a clock speed at the cost of performance. Simply by reducing the amount of logic between clockable flip flop pipes, and adding more pipes, the same functional hardware can run at a higher frequency with worse performance than the original.
