Actually it's worse than that. One of my Indian colleagues at work (here in the US) told me that the typcical Indian CS grad doesn't have much hands-on programming experience AT ALL (let alone any Unix, or embedded experience). Because of lack of money, most (obviously there are exceptions such as IIT) Indian universites have very few computers, so the amount of computer time is very limited - a CS degree over there is much more theoretical than hand-on programming.
You seem out of touch... Bangalore is one of the main outsourcing centers, and the environemt there is like Silicon valley to the extent of the frequency people switch jobs. Hire someone and then two weeks later they quit with a better offer. This is one of the problems many company's experimenting with outsourcing are having - the super high turnover.
If you want to feel sorry for anyone, feel sorry for the American developer trying to pay for an American cost living while competing for his job at Indian salaries.
Inserting into a doubly-linked list. You could of course copy back into an array if that was your source. This type of sort has it's uses - the worst case performace is O(n*lg(n)) vs the O(n^2) presorted case for quicksort, and best case (presorted data) is O(n). It's also obviously a natural fit if your data is in a list vs array to begin with.
There's a somewhat non-obvious mathematical result that any continuous periodic function can be decomposed as the sum of a series of sine functions of different frequencies. This series of sine waves is referred to as the fourier series of the function. The FFT (fast fourier transform) is an efficient numeric algorithm to derive the coefficients of the fourier series for any function.
One useful way to think of the FFT is as transform of signal data from the time domain (raw samples) to the frequency domain (the constituent sine waves). This is useful for all sorts of purposes such as being the first step in speech recognition, the basis of JPEG/MPEG compression,...
If Microsoft are saying that they can't read XML documents efficiently then I guess we have to believe them, but if that's really true it says more about their lack of programming skill than the the difference between reading a binary vs text (or XML flavor #1 vs flavor #2) document on a modern processor.
If a Windows-capable PC has enough oomph to render clippy in 3-D translucent splendor for Vista, then it's certainly fast enough to load an XML document.
The problem with nuclear fission (current nuclear reactors)is controlling a potential runnaway chain nuclear reaction. The fuel itelf is inherently dangerous and needs to be *stopped* from reacting too much rather than made to react. If the reactor fails there's the potential (based on design) of not stopping the reaction....
The problem with nuclear *fusion* (what we're talking about)is exactly the opposite - it's getting a reaction to happen in the first place, and to keep it happening. The fuel in of itself isn't going to do anything - it very much does not want to react. The job of a fusion reactor isn't to stop a reaction but rather to make one happen. If the reactor fails, then it's more like your car engine failing or an electric heater failing - the action stops, rather than getting out of control.
You don't need to test it to know it's a lot of bunk.
It's a given that a female will usually have a "female voice" (not just pitch but formants, inflection patterns etc also), and a male a male one. For physiological reasons larger people tend to have deeper voices, and smaller people higher ones, but not always so. A larger nasal cavity (big nose) will make nasalized phonemes more pronounced.
Beyond that, a skelton will tell you nothing of the quality of someone's voice, their accent, whether it indeed is a high or low voice (or the spectral details in general), their speech patterns, etc, etc.
For all we know Leonardo was a castrato who stuttered with a fake french accent and Mona Lisa had a nasty high pitched whiney voice.
If you look at the traits that are unique to humans, you're hard pressed to make the arguement of how and when these traits developed via evolution, and didn't develop in other primates.
And my next point again is lengthy debate, but I one I still make. Humans have some really unique aspects about us as a species. We have advanced language. We have art. We have complex emotions and psychology.
But yet if you look at the DNA then (just as Darwin predicted) we have very few differences from a chip (~98% common DNA). It'll certainly be interesting when we eventually learn precisely what the changes (esp. in the brain) are that these differences encode for, and how they account for our greater intelligence, but I can guarantee it's not going to be very profound:
- less hair - less muscles - incrementally changed face - incrementally changed brain - etc
The incrementally changed brain may make for impressive differences in functional capability, but the changes themselves are going to be nothing much more than "more here, less there", "more connections here, less connections there"... No harm in being awed by the functional changes that result, but it doesn't make the actual DNA and phenotype changes any more profound.
For that matter how would they know that you are encrypting in the first place, and have any keys to hand over, unless they are already snooping on your communications, which they claim they arn't.
Yeah - that sounds exactly like the Windows model... You get working drivers with the OS, and manufacturers update them when the OS requires it. For the vast majority of people who want to RUN linux rather than hack it this sounds like a GOOD thing.
If you do want to hack your driver source and compile it yourself, then nothing is stopping you from doing it for open source drivers.
The USA... Do you see a lot of dollar-rich foreigners buying up the homes in your neighborhood? Didn't think so - neither do I. I do see Americans buying them with 6.5% mortages though... single income engineers buying $500K houses...
Real estate isn't going up because the dollar is cheap and foreigners are buying; it's going up because interest/mortage rates are low and people can therefore afford to borrow more money - more buying power is increasing demand.
As soon as mortage rates rise, then watch out. A modest 3% rise from 6% to 9% would mean that your monthly mortage payments have increased by 50%, which will force panic selling by those without fixed rated mortages, and will drastically reduce the number of people who can afford houses any any given level, resulting in reduced demand and (maybe considerably) lower prices.
It's possible that we could alternately see flat a real estate market for years as it corrects by salaries catching up rather than prices dropping, but that requires people to be able to hold on rather than sell as mortage rates increase. My guess though is that we'll see forced selling by people who have over-extended themself wihout the protection of fixed rate mortages.
I don't think it really makes any difference how IE's near monopoly (85% share) came about - just that fact that it is now in that position.
Google's legitimate complaint here is that Microsoft is using it's monopoly position in one area (browsers) to stifle competition in another (search). Same as they used their OS monopoly position to stifle competion in browsers (all but kill Netscape by giving away IE for free)- which they've been found guilty of in court.
I'm not sure what the remedy might be though. Perhaps banning Microsoft from paying vendors like Dell to keep the MS default if Google are willing to pay to change it? (assuming this really is a *configurable* default in IE7 - can anyone confirm)
Actually, what that article says is that surprisingly Yahoo did NOT use the Inktomi search engine, but rather used the accumulated search engine expertise they had aquired to build a brand new one from scratch.
I don't think Yahoo does need Microsoft, but unless they've got a "poison pill" in place to prevent a hostile takeover, there's nothing they could do to prevent Microsoft buying a large chunk of stock and the voting rights that come with it.
True fact: The minimalistic 6502 (which had been used in Acorn's BBC micro & predecessors) was the inspiration for the ARM RISC CPU (formerly Acorn Risc Machine, then renamed as Advanced Risc Machine).
What you're describing isn't a a computer scientist, but rather an programmer working in a field where math is needed.
One could say the same about any specialized domain where the programmer needs to know about the domain itself as well as core programming (& maybe computer scientist) skills. Just because someone working on a radar system needs advanced math and someone else working in the bioinformatics field needs a knowledge of genetics doesn't make advanced math or genetics a prequesite to be considered a programmer or computer scientist.
I would say the difference between computer scientist and programmer is really mostly one of skill level and focus. A computer scientist is someone capable of designing and analyzing algorithms, data structures, programming techniques, etc, etc, and who is concerned with the art of programming in of itself as much as it's application.
Apparently Ask.com is now (or was it always?) powerd by Teoma's search database.
I just gave it a try ("emperor constantine") and on that search it does seem to give notably crap-free results. I'll stick with Google, but I've added Ask.com to my search bookmarks that I resort to when the Goog fails me.

Well this is quibbling over semantics... if you use a B-tree like structure as "random access" index into a linked list, then is it a list or a tree?
By maintaining a temporary hierachical index pointing into it... Or just use some sort of balanced tree instead - direct O(log(n)) insert.
Inserting into a doubly-linked list. You could of course copy back into an array if that was your source. This type of sort has it's uses - the worst case performace is O(n*lg(n)) vs the O(n^2) presorted case for quicksort, and best case (presorted data) is O(n).

I think you mean bubblesort rather than insertion sort. An insertion sort is O(n*log(n)) if you use binary search to find the insert point.

Not necessary - it's inherently safe.

The 6809 was a great processor, but it was really an 8-bit / 16-bit hybrid, so it seems a bit unfair to compare it to the 6502.
I think the 6502 was clock-for-clock faster.
True fact: The minimalistic 6502 (which had been used in Acorn's BBC micro & predecessors) was the inspiration for the ARM RISC CPU (formerly Acorn Risc Machine, then renamed as Advanced Risc Machine).

It's FUD simply because there's no reason whatsoever to believe that Linux does violate any Linux patents.
For that matter Linux doesn't even use Clippy.
An undercooked egg-white omlette served on a chrome plate?
Yeah, but wait for Vista...
Clippy will be doing backflips in 3-D. Think of the productivity enhancement!
