Are all of your dynamically allocated resources released if an exception is thrown? Are you sure you are looking everywhere it can be thrown?...constructors, passed argument variables, wierd autoptr like things, inside collections?
I like C++ a lot but exception handling without a finally block or automatic garbage collection is immensely difficult.
My grandfather build a homebrew kit years ago in his back shed. It was a box lined with insulation foam, a fan a lightbulb and a thermometer. The fan constantly ran and the thermometer turned off the lightbulb when the box became too hot. It constantly turned out great beer and I still use it today. He showed it to someone who worked at the local brewery and he said that he wished he could have such good temperature control on his vats.
You should only go high tech when you have to. Why have a computer control your homebrew or doorbell when low tech will work as well or better? Save your tech skills for things you can't do with primitive equipment.
You are an honest man, but I totally disagree with you.
The only problem with the idea of an elite like you describe is that it will be based off hereditary lines as only the rich will be able to afford to live & breed. Many people who have given great things to humanity have come from the middle or working class. Removing the ability for these people to be born, contribute, live and reproduce because they were born to poor parents is a really shitty idea.
Every time the US government locks away a person in jail, or buys a weapon for the offence force some people with very close ties with the government get richer. Think carefully whether you believe that is a good thing.
From an article by Hunter S Thompson:
War is an option whose time has passed. Peace is the only option for the future. At present we occupy a treacherous no-man's-land between peace and war, a time of growing fear that our military might has expanded beyond our capacity to control it and our political differences widened beyond our ability to bridge them. . ..
Short of changing human nature, therefore, the only way to achieve a practical, livable peace in a world of competing nations is to take the profit out of war. --RICHARD M. NIXON, "REAL PEACE" (1983)
Richard Nixon looks like a flaming liberal today, compared to a golem like George Bush.

House PRICES have gone up 200% in the last few years here in Australia. My granddad bought his house on a block of land for 1 years labourers pay. It would take 5-6 years programmers wages to buy that same house today.
How are they going to get money to pay rent and buy food, learn or play games if there are no jobs?
In a perfect world removing the need for human labor would bring about a utopia where people are free to do as they please. In reality it would mean that the rich and powerful no longer have a need for the large bulk of humanity.
Look around the world. All of the earths crust has been divided and fenced off. You now need money to buy the things you need to live - physical space, food & water. No jobs = misery for the mass of humanity
Lets not let facts get in the way of feeling good about ourselves. There is a slight problem - gun related crime has INCREASED in Australia since the "tough new gun laws" were introduced.
The idea that people from cooler climates are more industrious and noble was a very popular theory during Victorian times in England. The English had great respect for the hardworking Nordic people and it probably didn't hurt in justifying the domination of tropical countries under the British Empire.
George Orwell debunked this by stating if you took this argument to its extreme, then the Eskimos would be the most industrious and hardworking people in the world.
We are used to being a favoured outpost to an empire and have been in the process of jumping ship from the UK to the US since WW2. This seems to be the way people want it, seeing how they just re-elected the PM (sigh)
Our major trading partner is Japan and most schools teach an asian language... but I think we'll remain culturally tied to the English speaking world forever. You don't just cast aside the influences of western civilisation because you live on the other side of the world.
I saw some research a few years ago using brain scans that found that when talking, speech centres of the brain light up while other high level brain functions are reduced. They found it is literally true that you can't talk and think (as well) at the same time.
When I read this I figured that would just about put an end to speech recognition apart from very simple devices humancomputer stuff like fast food drive throughs, air conditioners, TVs etc. I don't want to say "main-open-bracket.. close bracket curly brace" for instance.
The "Syntactical sugar" allows the programmer to customise the language so that they can program closer to the problem domain.
Hiding the complexity of operations behind "sugar" allows the programmer to recognise mathematical conventions of relationships and operators and thus more quickly understand the code or to write it.
It is possible to write it without the sugar (heck, you could write it in assembly) it just takes more effort to do so and far more difficult to verify correctness. On large, difficult projects like the poster described, program complexity and the limited size of the human mind becomes a real problem, and anything you can do to reduce confusion and work at a higher level helps a lot.
Read a Java book from the 90s and you will see them laughing at C++ and how useless, dangerous and misguided templates are. The Java containers perform all kinds of convoluted tricks to make do without them, and now, with Java 1.5 they finally admit that templates have a use.
They did all along. Java needs them now, and they needed them then.
You can use use C++ STL vectors with at() when you want bounds checking or use a direct index when you don't. Thus you can keep the backwards compatability with C and have the choice of sacrificing safety for speed when you need it.

Yep, and have a default state that is expected by everything (matrixmode = modelview, culled faces on or off, depthmask etc) change it if you need to but put it back when you're done. PushMatrix() then PopMatrix() help to get back to the original state. Easy.
The hard stuff with 3d is the maths & knowlege, not the API....
I used to think they should have function overloading too, ie glVertex( 1.0f, 1.0f, 1.0f ) but considering the massively varying performance based on data size (ie float vs double) knowing exactly what size you are sending across the bus is very useful. It is only 2 or 3 extra characters... just think of it as extra strong typing and let it go.

I have read both Practice of and Pearls and noticed a significant overlap in content (even to the extent that both use as an example text generation using Markov chains). Both are good but I had more fun reading Bentley and he got into more hardcore algorithms etc.
Q2 used to run fine with 64 megs of ram while these guys are probably using 256 or 512mb when performing these benchmarks (they don't say). Fine on a PC where RAM is cheap, but remember that current generation consoles still have 24-64mb.
Also, Q2 was written for a time with significantly different CPU:GPU performance ratios (eg before Hardware transform & lighting) so the benchmarks don't mean much.
I have seen JOGL and I am quite impressed with it, I wouldn't be suprised to see multithreaded Java being used in the next generation of consoles. Assuming they can do something to guarantee near-realtime performance.
I used to live and work in North America too. Maybe it was just the company I worked for, but the corporate climate was noticably different from back home.
We were told on day 1 that this company was a wonderful meritocracy where your spot on the ladder was based solely on talent. Of course this was bullshit, but those who were in higher positions believed it as it was flattering to them and justified their position.
With this mindset it wasn't much of a stretch to see those who were below you as deserving their inferior status, and to treat them with contempt. It is different here, sure there are some jerks like anywhere, but we also believe that if someone has a shitty job or is out of cash they might have had a run of bad luck and so they don't deserve our contempt. I have never had a boss in Australia that woudn't eat or have a beer with their workers.
I couldn't afford an apartment near the beach in North America either, which is one of the reasons I am glad I am back in Oz.
Just to clarify here: This works in Australia because we have preferential voting, and voting for 1 candidate doesn't mean taking a vote away from your next choice.
It doesn't work like that in America where it really is a 2 party system and voting for a 3rd is throwing away your vote. Americans should vote for the person who is most likely to win against the person they disapprove of.
It is vitally important that you Americans do go out and vote, the whole world is effected by the outcome of your elections but only 300 million of the 6 billion are allowed to vote. The rest of the world pleads to please make Bush a 1-termer like his old man!
I think he was being ironic, taking the position of the person who thought of the policy to expose its lack of fairness. Read his last sentence again, it is plain that he doesn't think the process is a fair one.
'a process configured to run under an administrative privilege level' which, based on authorization information 'in a data store', may perform actions at administrative privilege on behalf of a 'user process'."
A user can't write to a graphics card directly so it communicates over a network to an X-server (which is running as root) to have it perform operations on its behalf.
It still exists, you just don't see it because America outsources its slave labour to third world countries and an underclass of semi-illegal immigrants. It works well, and not just to provide below minimum wage workers and ensure a supply of cheap crap in Walmart. Warcrimes are a breeze when done non-military personel in foreign countries.
Empires have always been about exploiting foreign territories for the benefit of the homeland, but the US is the first to think (not just say, they are true believers) they are doing the rest of the world a favour.
