That's completely wrong, actually. Light always applies some momentum to what it hits, the difference with circular polarised light is that it imparts a spin.
Linear polarised light is the sine-wave shape you've probably seen before, circular polarised light is essentially a spiral around the direction of travel. See: http://en.wikipedia.org/wiki/Circular_polarization
It's used in 3D cinema glasses because there are two kinds of circular polarized light (referred to as left and right handed), which spiral opposite ways and won't go through each other's filter, and because you can rotate the filter (say, by tilting your head) without affecting the image. On the other hand shutter glasses require power (and need a high framerate projector and some kind of synchronisation) and linear polarised lenses only work if you keep your head very level.
What does zonealarm do that the windows firewall does not?
Windows firewall does: Inbound filtering Outbound filtering Both allow and block rules IPv6 support Filtering by application Filtering by windows service Filtering by IP protocol (TCP, UDP, ICMP, IPv6 and several I don't recognise, and also "custom" for specifying protocol number) Filtering by TCP/UDP port Filtering by ICMP message type Filtering by source IP (both for incoming and outgoing rules) Filtering by destination IP (both for incoming and outgoing rules) Filtering by local adapter type (wired/wireless) Filtering by user-defined network trust level (home/private, work, public) Filtering by IPSec being used/not used Filtering by authenticated remote user / computer (for incoming IPSec connections) Filtering by authenticated remote computer (for outgoing IPSec connections)
In this case apparently a fair few people bought games and then didn't get to download them before the website shut down. It's not DRM, but you'd still be pissed off.
The built in firewall allows apps to give themselves permission to access the internet. So that means that spyware and other crap that a firewall is supposed to block... Can give itself permission to go online.
Only if the app is allowed to run as admin. And if it's running as admin, you're hosed anyway.
Windows applications will trigger a "do you want to allow this program through the firewall" prompt, easing setup. I haven't seen that on Linux.
You also get independent firewall rules for being connected to different classes of network: domain, work, home, and public. This is invaluable for laptops (which will basically turtle on a public wifi). Again, I don't remember seeing this feature in any Linux distro either.
I've since moved to an OS where I don't have to jump through hoops to make sure I'm not running as Admin all the time. Before you jump to any conclusions, I mean Windows 7, though I do run Linux on my media PC.
Jump through hoops?
Windows 7 with an admin account with UAC enabled (default) = Linux with a limited user with sudo permission Windows 7 with a limited user = Linux with a limited user
If you run as a limited user on 7 then the UAC prompts become admin login prompts, so it's not too hard to actually run as a limited user and still be able to do adminy things if you want. There's not a lot of point though, you might as well just use your admin account, UAC'll make it act as a limited account.
Actually, the extra virtual memory space program-side is far more important than the extra physical memory space ever was. Typically, a 32-bit program is limited to 2GB of address space, including actually used ram, memory mapped files, reserved but unused pages (e.g. the stack growth area), memory mapped device memory (e.g. graphics mem) and the program and its dlls. Thanks to fragmentation of the address space by all of these, a program can fail to allocate memory without even getting close to 2GB of ram use. I could, as a proof of concept, write a program which will fail to allocate a 512MB block while only using kilobytes of ram, simply by requesting one 4kB memory page from every 512MB through the address space.
64-bit software resolves that problem (at least until we get programs trying to allocate exabytes of ram in one block)

"By the time Firefox will make GPU acceleration work right, which is probably 1-2 years, two video card generations will come and go and the technology will be already obsolete. We'll then have 12-16 core processors capable of working with video as fast as they plan to make video work with GPU now."
And by that time we'll also have 300 core GPUs that are 50 times faster than said 16 core CPUs.
The nVidia GTX 480 is already a 480-core GPU (out of a 512-core die for yield reasons). Yes it's quite fast...
Not 100% accurate. Windows 7 includes direct-x 9 itself (there's not much to it), but not all the different d3dX9_??.dll extension files. Those are what you have to install.
The DX web setup will bring you up to date with all direct-x 9 onwards extension files, regardless of whether you're running XP or 7, x86 or x64, Home or Ultimate (just look at the comprehensive supported OSs list!).
Any older versions of DX are supported, you shouldn't need to install anything for them.
I first used 3D glasses in UT2004 (with a CRT display and wired shutterglasses, just like you). It made such a difference, mostly when dealing with delayed-impact weapons like the rocket launcher. Being able to easily gauge how far away someone was made figuring where I needed to aim to hit them almost cheating-easy. On the other side, seeing a rocket flying and being able to tell exactly where it was going made them so much easier to dodge!
I tried it in quite a lot of games, and it really does make an incredible difference to immersion.
"the average life of the components are severely shorter than normal" surely means "the component failed within its warranty". I don't see a problem with failures outside of warranty, they should be expected. If you want something that should last for a long time, get something that's "guaranteed" to last a long time. If something fails its guarantee, then the producer already has to pay for that mistake.
I'm the same. I don't like the texture of tomatoes, or oranges, but the flavour is fine. I think it's the same with mushrooms. I can taste alcohol, and probably a couple of other things that make beer and wine taste awful to me. Don't dare say "it's an acquired taste". Sweet wines are better, as are things like smirnoff ice (basically vodka+lemonade in a bottle), and I've recently been getting a taste for whisky (a couple of friends have good taste in whisky) and an icelandic drink called "brennivín". But even when I drink something I find drinkable I don't drink to excess, I don't know if it's because I don't like not being in control of myself, or what. Well that and drinking a few tends to depress the hell out of me instead of making me more lively. I lose my inhibitions and that makes me stop doing things. Strange...

ZEBra.
IPv6 includes multicast IIRC.
IPv4 multicast is basically broken by NAT, so is unlikely to ever get used on the internet itself.
What does zonealarm do that the windows firewall does not?
Windows firewall does:
Inbound filtering
Outbound filtering
Both allow and block rules
IPv6 support
Filtering by application
Filtering by windows service
Filtering by IP protocol (TCP, UDP, ICMP, IPv6 and several I don't recognise, and also "custom" for specifying protocol number)
Filtering by TCP/UDP port
Filtering by ICMP message type
Filtering by source IP (both for incoming and outgoing rules)
Filtering by destination IP (both for incoming and outgoing rules)
Filtering by local adapter type (wired/wireless)
Filtering by user-defined network trust level (home/private, work, public)
Filtering by IPSec being used/not used
Filtering by authenticated remote user / computer (for incoming IPSec connections)
Filtering by authenticated remote computer (for outgoing IPSec connections)
Looks pretty decent to me.

The PS3 has both a slow opengl implementation and a faster native API. Guess which one gets used.
Use another? You mean starting it as a process?
Because that doesn't sound like a job for a firewall...
So he did.
That'll teach me to read slashdot early in the morning...

Would you prefer a blacklist?

I posted the comment and it didn't show up. Looks like it did eventually.

My cat (which lives with my parents, because my rented place doesn't allow pets) finds the fruit basket comfortable.
I'm pretty sure I wouldn't.

No offence, but if it's out of warranty, you can hardly complain about it...

Oh and thank god it isn't based on the god-awful d&d MMO. Just saying.
