It's nice to know Blender is good, but on some PCs it doesn't work correctly, including mine:

Maybe it's just an ATI driver problem, but I don't understand what kind of interface they are using so that it doesn't work at all while all kinds of 3D games and simple GTK/QT apps work well...:(
An Ubuntu installer that you could download and double-click on, and that would automatically resize your partitions and leave you with a double-boot system? Here: http://wubi-installer.org/
It's still beta, but it does the same thing as the debian win32 installer.:)
"Is it any wonder brain-drain is so much of a problem?"
Isn't the brain drain mostly going towards the US?
"if US drug companies developed multi-billion dollar treatments for major diseases, then Europe decided to just use them without paying anything."
I can't agree on the drug patents for major diseases, sorry.
Just put Africa instead of Europe in your phrase and it sounds horribly wrong.
If this happens, I want free legal internet TV! I already watch a lot of TV shows on the net thanks to sites like youtube and dailymotion (and the great sites that link to the content on them;) ). Unfortunately, those videos regularly get removed because of copyright issues.
Now, by enforcing ads, they could finally upload copyrighted content and even organize it on the site, so people don't have to search for it. Of course, people can just do something else while the ad is playing, but it's the same for TV!
For people who don't have a TV, flash videos are great. That way, it sometimes becomes unnecessary to download movies and TV series over P2P, torrents,rapidshare&co. This is especially true for TV shows, where I don't really mind having a "bad" quality.
I know there are already some legal free internet TVs, but their content is often not very interesting. I want great movies and TV series!

Interesting. This makes "24" even more credible. There are always some security breaches, moles, stolen keycards and laptops... I really wonder why there still hasn't been a major terrorist attack on the USA except for 9/11. Maybe they'll wait for the national internet reboot (yes, national, that's what slashdot said ^^) to exploit more security breaches.
I am one of those people. ^^'
Or to be more precise, to me it meant something else: CS=Counter-Strike:P
When I first read the title "The Death Of CS In Education?", I was thinking of the end of Counter-Strike in school computer rooms!

Sorry, first time I was posting.
I didn't pay attention to the fact that it was in HTML by default.
Here it is again but in an easier to read form:
1)I read a lot of comments explaining the algorithm and everytime they say it uses an iteration (like the Newton-Raphson method) to approximate 1/sqrt(x).
But the problem is I don't see where the iteration is! I have already done some C and C++ programming, but I don't understand how this code snippet can iterate without any loop.
I don't see any "for(...)" in it.
Can you do iterations simply with this line?:
i = 0x5f3759df - (i>>1);
As far as I know ">>1" simply shifts the bits to the right and 0x5f3759df is simply a number in its hexadecimal form. So this line looks like a simple substraction to me.
So my question is: How does it iterate?
2)There is some C-code I didn't understand:
float xhalf = 0.5f*x; x = x*(1.5f - xhalf*x*x);

slightly off-topic:
"If this was successful... whats next, the auto theft movement for "Rightfully freeing car from their owner for anyone to use."?"
Car sharing is actually a very good idea. :)
Not that people should be forced to share cars they own, but a more extended use of car sharing, PRT and public transports would be very good.
