The company I work for often receives data from, and shares data with, Oak Ridge National Laboratory. The data we share is regarding the environment, specifically diesel emissions. Clearly the research benefits U.S. citizens and poses no security risk and should therefore be publicly available. But there are definitely cases where data should not be made public. Nuclear energy research, any weapons research, and combustion research could fall into that category amongst many others. Sure tax payers paid for it, but that does not mean that they should possess the data directly. There would be nothing stopping the average Joe from putting that data into the world domain. Then the world, who hasn't made any contribution to the research, financially or otherwise, now has this information that U.S. taxpayers footed the bill for.
It was probably a bad example, but I'm sure there are cases where you wouldn't want to actually inhale the gas because it's toxic, but it could be educational (and possible) to recreate the smell using other non-toxic compounds?
You know how you're always told, "Don't smell the test tubes directly!! Waft instead!" Well, wouldn't it be cool if instead of opening up a chemistry handbook, you could pull up a compound on a computer and as part of the entry it could generate its smell for you? It's a lot safer and a lot more practical than having kids huffing off a test tube to find out what the sulfur dioxide they just created smells like.
My numbers may be slightly off, but let's say that each Microsoft programmer makes $60,000 USD per year. If he writes 5000 Source Lines of Code per year (this number appears to be high), that means $12 per line of code. At 40 million lines of code in Windows XP, that means that it costs Microsoft roughly $480 million USD to manufacture XP. I understand there are many other costs, but Microsoft claims sales upwards of 250 million copies. So that makes $2 per copy of XP maybe a little more? I'm not sure if that includes OEM or not, but at a minimum of $80 USD to purchase a license... Perhaps someone has better numbers, but that's an amazing profit margin.
I've never taken the class, but this problem is assigned as the final project in a senior level Orbital Dynamics class at the Univ. of Notre Dame. A numerical simulation is done, and it's my understanding that the physics are non-trivial. Maybe the prof will see this article and lend some insights.

No, in fact they are talking about boiling water; a.k.a. 100 degrees Celsius. As people have pointed out, there are two reasons. Evaporation is a cooling process (that's why you sweat), and during evaporation liquid mass takes a gas form, thus there is less of your ice cube to freeze. And distilled water doesn't freeze "faster" it freezes at a higher temperature than water with impurities. Hence, people in the north applying salt to their streets.
Your explanation makes perfect sense, but I have this same question myself. The drag at that altitude and above Mach 1.0 becomes less (this is why the Concorde flies at 52,000ft). That deceleration to a velocity of 500mph less than the absolute velocity of the shuttle is extremely high under those circumstances.
Eiffel is excellent for this... I am a college student and we developed in the language last semester and for a final project created a cross-platform board game with a GUI. And according to eiffel.com, an OS X version of EiffelStudio is in the works. I'm a huge fan.
Ok, a plug for the Eiffel programming language. For cross-platform development of a GUI, you cannot really do better. Without a large development team, you will never get your software working on one system and then ported within a reasonable amount of time. Unless, your GUI development is cross-platform from the start. Eiffel is extremely quick and easy to learn (the goal of Bertrand Meyer is for every Eiffel programmer to be an expert Eiffel programmer). EiffelStudio is available for Solaris, Linux, and Windows. Same code compiles on all platforms. As for OpenGL, there of course exists EiffelOpenGL. If you are concerned about whether there is success with this language, Eiffel is used to develop all sorts of large systems, including CAD/CAM programs. Look into it. The widgets are so simple it's hard to not give it serious consideration.
There is definitely a free version available, though the executables created using the free version are not to be distributed commercially. http://www.eiffel.com, and click on Downloads. Then you will understand free.
Well, as a current student at the University of Notre Dame, Eiffel was used in our Data Structures course. We basically had two options, Eiffel or C++. Not a lot of people picked up on Eiffel simply because they were stubborn. But as a whole, the Eiffel coders had consistently better projects and overall success. It's purely O-O, so that takes some getting used to. The Design By Contract is an excellent tool for writing perfect code the first time, thus getting a larger systems to market faster. And the libraries that are available are excellent. The STL is simply not good enough relative to EiffelBase. Bertrand Meyer, founder of Eiffel Software, gave three distinguished lectures here this week, and another to our class, and he's very convincing when it comes to his methodologies. It's a great language for teaching O-O and Contracts. Additionally, the same code runs on multiple platforms, and EiffelStudio is available for free for Windows and Linux. EiffelVision also makes it possible to create GUI's that will compile on Windows and Unix too.
It says 3-4 times to process the video? Does that mean just to encode or encode and decode? If it takes 3-4 times as much to both, then the CPU will be an issue. An 800MHz PIII will not be able to handle it well and chances are only dual systems of any kind will be able to handle it very well. There's a reason why Appple went to dual processor configurations. DVD encoding/decoding takes a lot of CPU usage as is.
The University of Notre Dame is doing basically the same thing. Though they do not cite security reasons, they have stopped all support of Win9x. And if anyone thinks the schools and M$ are not in bed, then take a look at the increase in academic pricing. Windows used to be $25 (as well as Vis. Studio, et al) but now they've gone to $45. Funny how that happens as soon as they mandate the upgrade to a new OS. And WinXP is just as vulerable to all the worms that 2k is (for the most part). For example, I accidentally left a share open for no more than one hour and the open folder was filled with Nimda. In other news our LUG is planning an install fest in the near future.
I just noticed this today as I was looking around the Apache site that most (if not all) of the Apache.org mirrors do not use 2.0? Anyone want to tell me why they don't use the latest version of the software they promote???
I just installed Jaguar (yes, I stayed up into the wee hours to do it) and I am blown away. The performance increase is nothing to be ignored and all of the other upgrades are excellent. All I want now is iCal.
MS changing the round function????? Anyone who has taken any sort of stats class knows that this is the proper way to evaluate rounding a number. This has already been said but people don't seem to be catching on. I cannot even believe that this yahoo got his post through. That's not a bug it's good programming.
I cannot say that I have this problem so much, though every time I have taken an exam which forced me to write code, we were allowed to cite a previously written function or whatever. In the cases where a completely new solution is needed though, I agree, the paper thing does not work. I feel much more comfortable on a computer than writing frantically. Giving exams on computers provide significant challenges for honesty though too. My two cents worth.
My university teaches a Pro/E based course, but thus far has only licensed it for our Sun machines. There has been a recent push to develop a Linux cluster on campus; this is just another step in the right direction. Additionally, we have found that the Windows version of Pro/E is extremely unstable.
He talks a lot about connecting your GBA to a Linux box, yet all of his screen shots are from Win9x. Hrm, can I all BS on this one yet or am I missing something?
AMD is not merging with nVidia damn it! I have it on good authority that Intel and AMD are going to announce their merger some time this week. Additionally, they are filing to end all contracts with Microsoft, effective immediately. They have not announced a new partner yet, and with Linus' resignation, everyone is in doubt.
How are they ever supposed to build a database of papers if they don't keep a copy of ones that are submitted? It seems like if one wants to prevent plagiarism, one needs to have something to check it against? And why would you ever need to check it for plagiarism if you're the one who wrote it... seems like you want to find out if it's within the limits or not... I think it's a great tool for profs/TA's who are suspicious and want to start a process... I recommended the site to my mom (University prof) a while back.
