Actually, you clearly see the thwo threads running on different cores in Windows XP and "jumping" from one core to the other in Windows Vista. That is consistent with the fact that in XP you get almost 100% CPU usage (baoth cores) when both threads re running and around 50% (one core only) if you pause one thread.
I think multithreading means launching multiple execution threads and it's up to the scheduler to assign each thread to a logical CPU, based on load. If you write and run a program that spawns two threads on a dual-core machine, with no other CPU-intensive software running, then you will notice that each thread is executed on a distinct CPU (core).
Unfortunately, like many other open-source projects (e.g., The GIMP), OO is an example of how developers refuse to connect with the end-users. Suffices to mention the cumbersome process of inserting a page number in a SWriter document: Insert footer + Right justify + Insert field + Select "Page number".
I agree. BTW, it's funny how the open-source evangelists evaluate posts... Anyway, the idea is that, if IT businesses are reluctant to embrace the GPL then there must be a reason. If your business model is to sell software then you probably don't want to open-source it. But again, I think the GPL has an important role to play in the IT landscape as it ensures that some code is shared at little or no cost. That is how the Homebrew started and all.
As a software developer, if you want to showcase your intelligence then you release the code under a license that allows people to examine the code but not repackage and sell it (e.g., the GPL). If you want to commercialize your intelligence then you release your software under a commercial license. Anything in-between is a trade-off: free marketing for the bigger fish and small bites for the rest. Managed code will always depend on the latest.Net/Mono update.
"Science (from the Latin scientia, meaning "knowledge") is, in its broadest sense, any systematic knowledge-base or prescriptive practice that is capable of resulting in a prediction or predictable type of outcome."
There is no doubt the climate change debate has a high political load, irrespective of its scientific basis (or lack thereof). Other than that, one of the things lay people should know about science is that it works with abstract models. Mathematics is the "mother" of all sciences in that it generates the most general models, and all other sciences try to generate models for real life phenomena. These models change as human knowledge advances; the process involves expression of contradictory points of view and vigorous debate among scientists. Unfortunately, this process is largely unknown to the lay people in some of the more developed countries where even evolution remains a controversial concept.
I once tried adding information to a Wikipedia article and the editor-in-charge (?) summarily dismissed and deleted my edits arguing that it's "irrelevant information". The article was about a movie and I was just pointing to a PC game based on the movie. But he just wouldn't accept that piece of information and had the right to revert the changes I had made and there was nothing I could do about it.
Thou sayeth sooth, but that works for Apple. Over the years they created an image of what they are and how they build machines and, hey, they found a niche for it. The 10% of the market they cater to looks exactly for such things in a computer -- aesthetical, overpriced, different, easy to use systems. Apple sell hardware, not software, which is just an extra reason for potential customers to buy their hardware.
I have used Apple desktops for many years but I will never buy one for the resons you mentioned. They are nice to look at and work with, though.
I've been exploring development options for both Maemo and Android. These are OS-es for mobile devices with relatively low hardware performance. That is why, IMO, native code is better than managed code for these platforms. On Adroid it is possible to run native code but not in GUI mode, which requires the Dalvik SDK (Java-like, therefore managed). There is an Android emulator available where you can run your code irrespective of the development tools you choose, with the restriction mentioned above. The Maemo emulator, on the other hand, is part of an SDK which is built into a particular Linux image and is Eclipse-based, thus limiting the choice of development tools for this platform. If I choose Linux as a development platform for mobile devices then I expect to have the freedom of Linux; AFAICS, with Android and Maemo that is not the case.
Perhaps IT as it was during the bubble years is mostly dead, or at least the bells and wistles that it came with for a while are. But that was only a commercial layer of "shadows and dust" the corporate world added to it. It's time to remember how it all began and what was the purpose of CS and IT in the first place. Time to rethink everything. Computers are machines that are programmed by people to do things that people are able to do very slowly, thus inefficiently. Like, guide rockets in space and traffic on Earth; find hidden meaning in large amounts of data; control other machines; help people learn and have fun; simulate virtual worlds. Forget the bold business plans and the $400K salaries. A computer is an extension of the human brain and software is an extension of the human mind. IT people will continue be valued insofar as they come to the IT world with knowledge in another field, as long as they also specialize in a non-IT-related field where they can use their IT knowledge as a sharp tool.
I was trying to put an ironic spin on the whole story when I mentioned the Zodiac. Isn't that what astrologers say? That you destiny is controlled by your date of birth? On a more scientific note -- that article reads: "We document large seasonal changes in the characteristics of women giving birth throughout the year in the United States." Therefore, the conclusions apply, at best, to the population in that particular country/population. And it seems to me very much like science with a political edge.
"From its position above the battlefield, the elevated sensors will allow incoming cruise missiles to be detected, tracked, and engaged by surface-based air defense systems even before the targets can be seen by the systems." -- I guess size... ups! I mean, detection range is really critical. If the enemy can detect the blimps before the blimps detect the enemy then a long-range enemy ground-to-air missile can easily bring the blimp down.

That's right, publish that information on ./ maybe someone will become "creative" and use that information to new purposes.

I just checked in Task Manager and Firefox has 27 threads open. You were saying?

This was a selfish and thoughtless act. His own security and that of his country may be at risk eventually.
NASA TV is a live documentary, so perhaps that's how it should be. It's a not a Sci-Fi movie.

That's the idea. But will they be able to find the... switch?

That's interesting... I wonder how the US would comply should a couple EU politicians send a letter "asking it to" wrap something up in its favour.
An OS that runs on 90% of computers in the world is a de facto strategic weapon.
The user doesn't have other options.

No Java (or .Net) developers will complain that speed is an issue. Otherwise they would be looking elsewhere.

This is absolute nonsense. I know many people who are Capricorns (born in December-January) and who are over-achievers.
that's funny, because even young human beings need to learn "good" from "bad", under adult supervision, it's not an automatic process.
No problem, Ubuntu for ARM will be out soon (it's already available for specific platforms).
