When they created stereoscopic 2D technology, they marketed it as "3D", even though it was nothing of the sort.

So now, when they're creating actual 3D technology, they have a marketing problem, they can't call it 3D movies even though that's what it is, because then people will associate it with the earlier, inferior technology. So now they want to call it VR??

It's not VR. It's a movie format with a fixed viewpoint. Sure you can look in all directions from that viewpoint, but you can't move around in this "world", because there's no actual virtual world to interact with. It's just a movie, not VR, don't call it VR.

Comment: Dawson found a bug in gcc 4.3 as well (Score 2) 239

Dawson points to an 'optimisation' in gcc 4.3: constant folding is done using the higher-precision MPFR library. At least the gcc developers seem to think it's an optimisation, but unless it's disabled by default, it is actually a bug. In the absence of undefined behaviour, optimisations must not change observable behaviour. And, as Dawson demonstrates, this one does.

If you need MPFR precision, you should use MPFR explicitly.

If you bump into something at 90MPH, there's a significant risk that you will get into a swerve and lose control. That doesn't happen at 45MPH, you just brake. But at 90MPH it takes 4 times as long to brake, and your braking distance is 8 times as long.

That's essentially what your patrol officer observed: Slow moving vehicles recover, fast moving vehicles crash. That holds regardless of who caused the accident; physics doesn't care about that.

Also, you should know that a 89/90 impact is 2.01 times as hard as a 44/45 impact. Twice the speed is four times the kinetic energy.

And why do you think those animations are there? Probably because MS's trial users reported back that they couldn't figure out how operate the damned thing, and instead of fixing the UI to make it discoverable, they added training.

I've never seen those animations, by the way. I didn't install the OS on any Win8 computer I've used, so why would I?

I do leave my computer on 24/7. However, being I moved to an area that is predominantly powered with clean energy ...

Which they sell to other areas when there's a surplus, and then that other area can cut fossil fuel use.

The world's marginal fuel is lignite. No matter where you live, if you spend more energy, you're gonna burn lignite. If you spend less energy, less lignite will be burnt. Shut down you damn computer!

In fact, there are a few things I miss from it when I have to do stuff on Win 7 (such as right-click the start icon to bring up all the admin options). And no, I don't use a touch screen or a laptop; just a plain old desktop with mouse and keyboard.

That button didn't even exist until after a lot of complaining. You can hardly complain about the complaining, when it gave you the very feature that you love so much.

As an aside, it puzzles me that you called the button an icon. But then of course, one of the countless usability mistakes in Windows 8 is the failure to visually differentiate buttons from other images and text.

On the bright side, it's nice to see US companies abiding by foreign laws for a change. For far too long they've gone with the attitude "we're on US soil, so we only have to follow US law", but now they're finally waking up to the fact that they have to follow the laws of every jurisdiction they do business in, or stop doing business there.

Is that a good thing? Case in point: The beta-free site refusing to accept donations, because then they'd have to be separately licensed to receive donations in 50 states. (section Why We Haven't Discussed Pure Donations). I worry that small and even medium size companies will just drop overseas markets, because it's too much hassle.

Like those obnoxious .com sites that only sell to North America. Usually they don't even mention the fact that they won't sell to you until you reach checkout, and they ask you to select your state, but not your country, that's implied. These last years my impression is that there are fewer of those sites, that the world has become more connected. I'd hate to see it go the other way.

Using 'piracy' to describe copyright infringement is hacker's jargon that moved into the mainstream. In the 1980's, the word was mostly used to describe software copying. The jargon use of the word is older than that though; describing a radio station without a license to use the spectrum as a pirate radio goes back to at least the 1950's.

You unjustly honor the term 'pirate' when you apply it to someone whose crime was facilitating communication.

Tell that to Piratpartiet.

It is a malware development kit, you know. Or rather, part of one. The bad guys use tools like this to create virus-scanner-proof malware.

1. Create 1000 random variations of your malware.
2. Select a variation that's given a clean sheet by Virus Total. If there isn't any, just create more variations.
3. ?? (*)
4. Profit.

And yet, somehow, electrical engineers are always seat-of-the-pants cowboy coders. At least the ones I know, I work with a few of them. They might be more disciplined with their core skill, developing hardware, but I've heard "let's add a pull-up resistor and see what happens" one too many times to really believe that. I don't have a problem with that, they get the work done. I just can't take seriously this notion some people have, that software engineers are sloppy amateurs and real engineers work to a higher standard.

Are you saying I should report my colleagues to the police for criminal negligence? They seemed like really nice people...
