This is a load of crap. If you're optimizing before even knowing where the problem is you can't be writing serious apps. The only programmers I know who do this are the same assholes who use globals because they're faster. Or manually unroll their loops in every case because the "know" it's going help. Or inline every method they write in C++. Or decide that they need to create all their member variables as real instances as opposed to pointers because the pointer traversal is too expensive.
If you exhibit any of these symptoms you should quit programming. Please. You end up making more work for those of us who actually know what we're doing.

1900 mhz is the US PCS range. You guys are 900 and 1800, we're 800 and 1900. What the original guy was saying is that he would like to get one of these phones in the U.S. but can't because the freqs. are all wrong. Damn those global conspiracies.
In the long run all we'll be doing is creating more terrorists. By lobbing bombs and going in to a country that is well and truly fucked, (that should be FUCKED), as-in, they have nothing, the soviets already decimated everything, we're creating our own little terrorists. That's a great idea, instead of having some small bunch, which we might be able to deal with, running around trying to mass-casualty Americans, we'll have every extremist around the globe training their kids and grand kids to kill the ugly American. We'll be like one big happy Israel, a police man on every corner, random bombings, any un-attended package gets searched, you get ass-reamed if you look remotely brown skinned. I love it. That truly is a better world, give the FBI and Ashcroft complete control of your life and inform the government (don't forget your ID card) when you go to take a shit.
Welcome to America comrade, here we're allowed to express our opinions and disagree with our government. Afghanistan is a death trap, and lots of our people and innocents on the other side are going to die because Cheney, Rumsfeld and Bush won't pull their heads out of their asses. Colin Powell is the only person worth two shits in the whole white house. Too bad he's not running the show.
I agree Colin Powell would be a great president. God, I wish he were right now. We have this enormous national tragedy and a buffoon is running the country. Every time Bush appears on T.V. I want to weep.
Give me a break. The editors of/. think they are (or most of them I guess) American citizens with the right and duty to speak their mind about their concerns. You're fooling yourself if you think our elected officials will ever be able to make sure this never happens again. It is our right and duty as Americans to make sure that our freedoms are not taken away because of knee-jerk reactions. Our country has a long running history of heinously violating the civil rights of individuals during times like these. McCarthy-ism, the internment of Americans during WW2, the rounding up of anyone outside the Republican National convention a couple of years ago. We have good reason to be afraid of this and it is important that these fears be addressed in the national "dialogue." Our freedom is what make America unique.
Yes, the Supreme Court will protect us! Just like when the Supreme Court overturned the internment of American citizens in World War 2. Oops, they upheld it. You must be thinking it's like when the Supreme Court overturned the guilt by association laws during the McCarthy era. Oops, they upheld those as well.
I'm disappointed as well. These are rights not privileges. We are going to sacrifice very real freedom for very unreal security.
Can you guarantee that the trade will 100% prevent similar tragedies? Can you also guarantee that no innocents will be taken? A false sense of security is less worth than a real awarenes of the risks.
Or it could be the years of training and cash we've been handing to terrorists such as bin Laden. But nah, we don't have anything to do with it, they're just evil scum.

Just the like the other cat said: You have a fundamentally insecure system. One or two trusted components (maybe more, pilot, flight attendants, random plants in the passenger list) plus 2 hundred untrusted entities. How can you secure a system where almost all of the elements are insecure? You don't. What you have is background checks and rectal exams to get on a plane, a feeling of security and no real security. What needs to happen (IMHO) is that we, as Americans, need to understand that freedom has a price. The price isn't informing the government whenever I move, or drive somewhere, or carrying a national identity card, it's responsibility. Looking out for each other and, as individuals, standing up against those who would abuse our freedom.
It's understandable how this would happen when we're all constantly told to not take responsibility or get involved. You're safer just doing nothing and waiting for it to end, just ignore them and they'll go away, let the government and the growing police state handle things, just sit down, shut up and take your medication.
Well, you'll probably never read this but:
1) Io completion ports have a bunch of threads associated and a bunch of devices. Devices are handles. These can be just about anything. Whenever one of the devices is ready (incoming network packets, io device ready for read or write, etc) the kernal awakens one (!) and one only thread to receive the event. The thread is chosen based on how recently it ran. The kernel choose the most recently run thread.
2) They're sweet because you don't have the overhead of thread creation (mildly expensive), no unnecessary context switches (some models wake up every single thread just to tell them they don't have anything to do), multiple threads waiting on the same pool of objects and some smarts as to which is chosen, limitless objects can be waited on, the OS is smart about the number of CPUs. If you have 2 cpus no sense in waking 3 threads. The kernel doesn't do that, it will choose 2 that are ready for action.
3) I don't know why WaitForMultipleObjects has that limit. But my guess is that it was never intended for many handles.
Actually WaitForMultipleObjects wouldn't be the way to go either since it only allows a maximum of 65 handles. As the original dude said, use io completion ports. If they are using WaitForMultipleObjects, they are truly sad bastards.
As for virtual methods, this is an implementation detail that really does not need to exposed in the language if it could optionally use better linker/object technology. The language implementation can decide which methods need to be virtual itself through global analysis at or before linkage.
This ignores the idea that you want to be able to explicitly tell the compiler which functions should be allowed to be "virtualized." How would that work out if the compiler auto figured out which functions should be virtual? Would you replace virtual with a "no_virtual" specifier? Changing explicit virtual declaration to an explicitly not virtual declaration? I'd be interested to see the pro's and cons of decision tree versus v-table. Any good links?

And the book 'Genome' is by Matt Ridley. While an interesting book and good for the beginner (in some ways) it is one view point and the presentation of the gospel of genetic research is biased. Read the two other books I mentioned to balance this book out.

Scientists don't get grants by being wrong, they get them by strongly advocating their position and killing others babies if necessary. I'm not saying that scientists don't contribute or it's not a great place to be or anything like that, but the reality of research is that there's not enough cash to go round and you don't get your piece unless you fight for it.
