While some people always propagate the use of generics/templates, I'm strictly set up against it.
While you get at first sight nice stuff like reusability etc. there are several reasons for avioding generics like an STD:
The type checking is much weaker thus introducing new potential holes for error to slip through.
You must make some assumptions about the used classes however verifying the correctness of these assumptions in nearly impossible.
The reusabilty "argument" is rubbish: that's what we have already OOP for. And when you now claim performance problems due to heavy stack/virtual methods use: that's an issue of the processor design not of the programming language. When you think that running serious software on system compatible to 30 year old rubbish is cool, then you must accept the performance of 30 year old waste in the same turn.
The above mentioned problems create new security holes. That's why the use of generics/templates in strictly forbidden in e.g. the banking sector.
Due to turing completeness of most template/generics systems the compiler is slowed down to 30 percent performance. More evil is that templates push the grammars into the Chomsky-0 type making secure (=100%) correctness checking impossible.
In old languages like Lisps the use of generics is usually strongly discouraged to users unless they are ultra-gurus due to the bad experiences. It's not clear why this should be different for Java or C++.
What you don't realize about Europe is that besides free trade they also impose social standards. Indeed richer countries are giving money to the poorer increasing the living standards there. That's why Europe works but the US version of free trade not.
Anyone propagating ethernet, IP and TCP for real time systems should be hit with a stick. Hard.

This will make our country more secure and safer from terrorism.
Furthermore all American pariotic parties are joined in this effort to fight terrorism - even Howard Dean is supporting personal identification schemes.
And remember we are at war - the war against terrorism. And in a war everybody has do to his share to ensure the victory of the forces of the free world. If that means that I have to give up some privacy, then I'll do my share gladly.
At WWII we had to make much larger sacrifices to save the free world and democracy.

The PPC chips don't have the heat problems of Intel's or AMD's product. So you can use smaller and more importantly more silent fans and cooling.
The only drawback is that they trade power/heat benefits for reduced performance - if main issue with PPC's. This makes me wonder why they don't use mobile processors from scratch.
An attacker who comprises Fermi Lab's systems has usually also access to the control of the large hadron collider they have there.
A manipulation can destroy important experiments. Even worse, they can't be sure whether the hacker has tampered the collider data. So they have to repeat all experiments from the last weeks.
Furthermore the hacker can do more than just tampering data. Indeed it can overload the collider resulting in an explosion. This would set off a cloud of toxic material threatening the surrounding villages.
Just because some fool edited "Andy" in the MyDoom binary, it doesn't mean that the real author is really called "Andy" or something like that. In fact the virus originates in Russia, so it's very unlikely that the author is really called Andy, but rather "Wolja", "Olga", "Oleg" or "Katjusha".
I rather suspect that this is a trick from Soviet officials the draw attention from the fact that this piece of internet terrorism comes from Russia and that their security is beyond repair.
Due to the folded design the quantum fields of the photons interfere and the optical resolution will be reduced. You get basically a standing photonic waves between the mirrors. Due to non-elatic reflection (the mirrors eat up some energy) the visual output is reduced. Furthermore with his design you'll get problems watching object which omit mainly red light - the mirror absorption is highest there.
This version inflation gets really on my nerves.
Huge numbers like 10.0 don't mean anything anymore. They want to suggest that the product is mature, well working and has lots of features.
But usually this isn't true. And the irony is that even Mandrake uses this numbering scheme. This makes it basically an oxymoron.
The only mature and stable distribution is usually Debian. But it is so mature that it even stinks.

Two steps:
Make bad system adminstrators personally responsible for the damages they create by not fixing security holes.
Give physical punishment to the virus writers. Money charges won't usually do the trick (paid by parents/community), but a decent spanking will teach them a lesson.
While the parent post was from someone to stupid to get a simple joke, I'll have nevertheless to eradicte such stupid prejudice about old people.
Although old people are old it doesn't necessarily mean that they are stupid and techonology hating. I have surely more high tech stuff than you, kid. And I do really own and buy new hot gadgets. And other old people do this, too. There are only two main differences between us:
While you might own the newest Apple computer I do own all Apple models from oldest to newest and will surely own Apple's last computer (when they go finally bankrupt), too.
Already after WW II in the late 1940ies there were the first mech projects floating around. We had basically everything you need: Diesel engines, decent valves from submarine technology for the hydraulic system, the usual control stuff, sufficiently small electric motors etc.
You don't need many electric amplifiers for the electric system because the main system would have to be hydraulic anyway. So vaccuum tubes would do.
However the projects were stomped due to several reasons:
Weight: these mechs would much too heavy for decent use (200 metric tons)
Stability: without high speed regulation these mech would just fall on the back when lifting something heavy or fire an anti tank grenade.
Reliability: the hydraulic system was every prone to produce leaks and it wasn't even remotely bullet proof. A single foot soldier could take it out with an old WW I gun.
The main idea of the law is to stop non-compliant messages by imposing financial punishment on the spammers. And this won't work. It very easy to avoid such fines, e.g. declare that you don't have any money and then use the absense of local citizen registers to "vanish" from the radar of law enforcement.
I think the real solution would be physical punishment. Just when the feds get their hands on the spammers then they can't avoid punishment. No more bad excuses. Of course, you won't do something imhumane like they do in Saudi-Arabia - cutting of fingers etc. You would just give them a decent spanking. And they would remember that. Furthermore this would be much cheaper than traditional punishment.
When I was young it was common to beat children for educational purposes. That was at the first decades of the last century. When you look now at history you will notice that the 2 worst war in history fall just behind this time. And in fact this education changed the way we though about violence: we didn't think that it was wrong to use violence if it was justified by our "ethical values", e.g. national needs.
This only stopped when beating children became more and more unpopular. My grandsons still have trouble to understand how I could German soldiers in WW II as a sniper - they view violence and especially killing as ethically evil.

I still remember who some very smart people warned in the 1920ies that the entertaiment industry would become due to media concentration too powerful and could get laws changed to their favor. Of course, hardly anyone took them seriously. We had only some movie industry in hollywood and the big competitor the German UFA was still alive and kicking. So the advised regulation law got passed. After WW II when it became clear that they were right, all proposals in this direction were stomped by McCarty as "communist agitation" - that why the big ones in the movie industry supported him.
And later, well, it was too late.
Which leads in the end to such things as the DCMA.
Lesson learned: always act preventativly or it will be all too late.
That's why I think that people should take this MS monopoly stuff more seriously.
I still remember the stories of my grandfather who worked at the federal post office how the amount of advertisment letter rised with the introduction of railway post transport. Before that messengers on horses of coaches had to be used. This had the effects that letter where relatively expensive and traveled very slow (4 months from east to west coast). And it was insecure due to hostile natives.
However all this changed with railway post transport. And so the amount of advertisment letter increased greatly. It even delayed the transport of legit letters, so that the post office had to use special (more expensive) rates for advertisment transport to keep to flood under control. Note that hiding advertisment letters as normal ones didn't work: the post offices clerk were allowed to open every letter and check which they really did regulary.
It's quite surprising that people have so much money to spend these days.
When I was young an offer to buy something besides houses or companies for 15000 $ would be considered to be a tasteless joke. Even for extremely rich people this would be too much. I still remember that there was much talk in the New York high society when Rockefeller bought his wife a collier for 20000 $.
It seems that capitalism had really achived what the communists always wanted: the make common man really rich.
Funnily in the 1930ies when some guys predicted exactly this development they were considered extremist fools even in academic circles.
