Yes, I do work with a large number of odd characters in my work:). But when you get used to typing them, you start using them everywhere. Just because you can.
Actually it was the other way around. Distance signs went metric many years ago, but only for new signs - nobody was in too much of a hurry to actually replace old signs until they needed to. There are only a handful of old, forgotten signs left in miles now.
In January 2005 the government finally got it together, and 58,000 speed-limit signs were changed in something like three days, and the new speeds were official from 20th January 2005. There was a publicity campaign to advertise what was happening, but I've no memories of anybody getting upset or confused. All new cars have km/hr as the primary (or only) speed on the dial.
True, but if the microprocessor's clock speed is hundreds of thousands of times fater than the FPGA, then you are even again. There's no clock speed for this device in the article so we can't really compare.
Clock speed often depends on the circuit design put onto the FPGA. If you got your FPGA design running at even 100MHz (not unrealistic), you're maybe 30 times behind a general-purpose CPU. But not only are you running hundreds of instructions per cycle, but those instructions are specific to the application and probably many times more efficient.
It's probably not useful for making short-lived applications faster, but for seriously repetitive number-crunchy work like weather predictions, oil drilling, etc, where there are trillions of small-scale computations, the highly-parallel nature of the FPGA has great potential.
Also, if those small-scale computations need to interact for any reason, on-chip communication is far faster than any chip-to-chip could be. And that's happening in parallel, too.
So who is right? Me or the colleague who eventually said that my reply to all was conterproductive?
I'd agree with your colleague on two points:
1) Telling people not to worry about computer security is just plain wrong. Users need to have it in the backs of their mind that while you are indeed trying to protect them, that relying solely on that is an accident waiting to happen.
2) Suppose an infected machine does make it onto your network? Since the virus can destroy files on remote network shares, it is, as I understand it, still possible data loss can occur on remote machines that are "immune" to the virus.
Maybe the better question is: Why do service centers charge so much? Seems like there's plenty of blame to go around.
Maybe this is the perfect time for the "easy" Linux distributions, like Ubuntu etc., to make inroads. "Whoa there, mate - before you chuck that PC, it'll cost you nothing to try this out. If you don't like it, you're still free to pay $400 and make the same mistake twice". I know I'd be happier to donate my time doing this for several people than to waste even one hour cleaning up a spyware-infested Windows box.
If I was unable to patent my idea, then there would be NO use in my pursuing it because a large company like MS could throw money to make their own solution after seeing my development. So how does THAT encourage me to take risk, go out and start a company, thus employing other people?
In a world of software patents your risk becomes getting sued to hell and back by somebody granted a patent on a scrollbar, double-click or something equally obvious. Where are you going to get the 6 or 7 figure budget to fight that in court? It becomes impossible to do anything without infringing on some dumbass patent or other.
If this application is visible on a public website, making it standards-compliant is a major step towards making it accessible to the partially sighted, blind or motion-impaired. The company may also have staff that fall into this category. Making the site accessible in this way could even be a legal requirement (depending on your country) and it's just the right thing to do anyway.
Which, of course, ignores the small point that the blanket tax applies to everyone, not just those who download music. A bit like paying a per-CD fee to music companies for every Linux install CD you burn. Reasonable indeed.
Because it's not always that easy. Have you ever tried convincing very busy people to apply a patch when Windows Update has completely screwed their machine twice before? They'd rather risk spending an hour cleaning up after than risk another full day reinstalling and reconfiguring their machines. Having seen what happened the last time, I can understand their point of view (even if I don't agree myself).

As much as I agree that people in general should walk lots more, it's also incredibly frustrating to be stuck behind slow people in a crowd after getting off a plane on the long walk to the main terminal. At least this guarantees a good minimum speed.

Denmark built an off-shore wind farm, which seems like a pretty good idea. The wind currents are stronger over the ocean, and it doesn't take up any land. Includes pictures.
An Irish company is also building one in the Irish Sea. It's supposed to be finished later this year.

I had a problem where my (RedHat 8.0) 500MHz K6-2 wouldn't play MP3s at all (unless you count white noise), but installing a more optimised kernel (i586 instead of i386, in my case) fixed it very nicely.

That doesn't really happen though. If it did, every major gun manufacturer would be out of business. What else are guns for? Largely thanks to the DMCA, the analogy is broken.

Why not? The algorithms may work best for small-grain problems, but what is any graphics program but something that computes thousands of pixels at the same time? I'd imagine image-processing (in general) is highly parallelisable at the pixel level.
