Comment Re:thrusting (Score 1) 594

IMAX 3D still uses linear polarization, and ghosting is a constant problem. The recent advance that really is driving the current 3D movie craze isn't digital shooting or projection but circular polarization filters as used in RealD, which effectively solve the ghosting problems all other polarized 3D systems have had, and are cheap enough to be disposable.

That list is missing one of the most important depth cues: motion parallax. It's not present in still images. It is present in video to a limited extent, but it doesn't account for viewer motion; only camera motion. The only way you'll get correct motion parallax for viewer motion in 3 dimensions is with head tracking or holograms.

Even if you've never used the Address Book app this information could be in there. In the OS X first-launch setup dialog it asks for your real name, and that gets automatically inserted into the address book. I'd wager that most people who use Macs have done this, so their real names are accessible to any website using this technique.

Additionally, though this is less likely, if you fill out the registration form during setup I believe that information also goes into the address book, so there's your home address and email too.

Net neutrality campaigners aren't just worried about "normal" internet connections, whatever that means. Net neutrality principles apply to *all* internet connections.

This situation is the reverse of the normal network neutrality problem. Normally you would expect AT&T to charge extra for the use of Skype, and that would be a clear net neutrality violation. Having Skype charge extra for using AT&T's network is less bad; Skype is not an ISP and there are many competing VoIP alternatives which do not charge. However, if AT&T is involved in Skype's decision to charge, for example if AT&T is charging Skype directly and Skype is passing that cost on, then it's still a net neutrality problem.

Comment Re:#1 reason I use Chrome? Translation. (Score 1) 347

There are tons of translation add-ons for Firefox. The reason it's not built-in is because it's not actually a feature of the browser; it's a web service. Chrome's translation feature works by sending your entire page to Google's translation servers. Mozilla doesn't run a translation server farm; it would be prohibitively expensive for them.

On the contrary. It is *extremely* rude to throw up a confirmation dialog before every trivial system maintenance task.

As has been pointed out below, System Restore is basically only useful for resolving problems so severe they prevent your system from booting. Once your system has booted you don't really need older restore points, and they take up a *lot* of space. Deleting them is absolutely the right decision for the average user. The *real* problem here is probably the UI for creating system restore points not mentioning the deletion policies and generally misleading people into believing that creating restore points manually is a useful thing to do.

These people creating restore points all the time remind me of the people who get obsessed with defragmenting their disks every night...

Comment Re:Larrabee (Score 2, Informative) 135

No, actually this is a separate effort entirely. This is a product of the same group which produced the "Polaris" 80-core chip, and is meant for research into communication models and memory architectures for massively parallel systems.

Larrabee is still ongoing as a separate project with a different focus. Larrabee is all about getting maximum throughput by adding a wide vector unit with a whole new instruction set to each x86 core. As far as anyone outside Intel knows, the plan is still to eventually release some Larrabee prototypes as-is (with the texture units and everything), and to develop a Larrabee 2 with the lessons learned that can actually compete directly with GeForce and Radeon in the graphics card market.

Comment Re:Spyware on my GPU (Score 1) 200

It's true that theoretically shaders can't do much, but shader compilers are imperfect, and since GPUs have no hardware memory protection, compiler or driver bugs could easily result in read/write access to arbitrary video memory, allowing a shader to directly read/write the contents of your screen, or corrupt important data structures to exploit the kernel-mode part of the video driver and gain complete system access.

Video drivers are complex and notoriously buggy gobs of code which run partially in kernel mode and were designed for speed, not security. Allowing any random webpage to make DirectX/OpenGL calls directly (even without shaders) is a huge security concern.
