As the VP8 vs x264 test is using SSIM, I found these important from the article about encoder cheating.
3. Making invalid comparisons using objective metrics. I explained this earlier in the linked blog post, but in short, if you’re going to measure PSNR, make sure all the encoders are optimized for PSNR. Equally, if you’re going to leave the encoder optimized for visual quality, don’t measure PSNR — post screenshots instead. Same with SSIM or any other objective metric. Furthermore, don’t blindly do metric comparisons — always at least look at the output as a sanity test. Finally, do not claim that PSNR is particularly representative of visual quality, because it isn’t.
How to spot it: Encoders with psy optimizations, such as x264 or Theora 1.2, do considerably worse than expected in PSNR tests, but look much better in visual comparisons.
4. Lying with graphs. Using misleading scales on graphs is a great way to make the differences between encoders seem larger or smaller than they actually are. A common mistake is to scale SSIM linearly: in fact, 0.99 is about twice as good as 0.98, not 1% better. One solution for this is to use db to compare SSIM values.
The Apollo project, even though run by NASA, was really a military project. It was an extension of the Cold War. It was all about beating the Soviet Union, and not about the science of getting to the Moon.
Any project to the Moon, to be cost effective, would have to use existing technologies. And it's questionable if the the President and Congress will fund NASA enough to develop those technologies.
I had to use the direct links, but noticed that the ogg version was 10% taller but the same contents. A skewing like this could easily explain bad perceived quality, did anybody else notice this or it is just my Firefox 3.5 beta on linux that's messed up?
10% taller visually? I think that's because that both videos were encoded at 704x576. That gives us an 11:9 aspect ratio for both, however the H.264 version has a 4:3 display aspect ratio set, so that it looks correct. It would be better if they had used square pixels for their raw source, so we don't need to compare anamorphic displaying of the videos as well.
"Hurin wedded Morwen, the daught of Baradund son of Gregolas of the House of Beor, and she was thus of close kin to Beren One-hand. Morwen was dark-haired and tall, and for the light of her glance and the beauty of her face men called her Eledhwen, the elfen-fair; but she was somewhat stern of mood and proud. The sorrows of the house of Beor saddened her heart; for she came as an exile to Dorlomin from Dorthonion after the ruin of the Bragollach."
First it should be Bregolas of the House of Beor, and not Gregolas. Morwen is the granddaughter of Bregolas, a Lord of the House of Beor. Beren is Bregolas' nephew, thus making Morwen and Beren first-cousins once-removed. Because of her beauty she is also called Edhelwen.
Dor-lómin is the land that she was exiled to. She was originally from Dorthonion, a region that overrun by Morgoth during the Dagor Bragollach (Battle of the Southern Flame).
Interestingly her relationship with Beren makes her Elrond's second cousins twice removed and also first cousin three times removed.
I believe all POWER derivative PowerPC processors are Big Endian only. The G5 (PPC970), a POWER4 derivative, is Big Endian only... that's why VirtualPC currently (unless MS finally fixed that) doesn't run on it.
Madden 06 is not a next-gen game for the PS2 and XBox. It still runs on the same game engine that they have been using since the game came to the PS2. Madden 06 (if it actually is released) for the 360 will be on a new engine and of course look much better than what appears on the XBox. Madden 07 will still be available with the same game engine for the PS2 (and probably XBox too). I still remember seeing Madden 2005 for the PS1 at the store. It's still the same Madden for the PS1 that you got in the late 90s. Just update rosters.
Remember the goal of BlueGene is to build very dense systems. Not only do you have to factor in the costs of the system, but you have the costs of the facilities. This includes costs of construction or renovation of the facilities to handle the power and cooling requirements of these behemoths. BlueGene/L in it's current incarnation is using 32 cabinets for it's processors. While Earth Simulator is comprised of 320 cabinets for the CPUs (an additional 65 for interconnects).
BlueGene/L is also much smaller than Earth Simulator. At 65536 processers you get 32 cabinets (2048 per). While Earth Simulator is 320 cabinets for the CPUs alone, not including the 65 cabinets for the interconnects. Construction of BlueGene/L is not complete it will have 131072 processors when it is fully completed.
All ASP video codecs will have to contend to their AVC cousins. DivX and XviD are still trying to squeeze as much performance out of ASP, but without breaking compatibility it's a losing battle. More people need to start working on x264, the opensource AVC (h.264) implementation.
At the end of TNG, yes. However, once Worf moved over to DS9, he ended up marrying Jadzia Dax. And Riker and Troi ended up getting back together in Star Trek 8.
The XBox 1, uses a stripped down Windows 2000 kernel. If they had used a standard Windows XP kernel, you might end up needing to wait 5 minutes for your XBox to boot.
The games are XBE (XBox Executables), which are derived from standard EXEs -- minus the cruft that it has gained in the sake of backwards compatibility.
The XBox 1 uses a modified version of DirectX. Once again, it's a stripped down and enhanced version of the standard DirectX. They took out all the cruft it has gained during the previous development, and added things specific for the hardware.
And finally, the other reason not use simply use an "off the shelf" OS, is you don't want to make your system look like a cheap PC. People will buy it just to be a PC, and run other things. Since game companies lose money on their hardware, you don't want thousands of people running out and getting it and not buying any games.
Remember for consoles, you have very specific hardware requirements (they are set in stone). While in a PC, you have a wide range. Developers can't simply concentrate on performance enhancements for a particular configuration.
Also, XBox 360 development will probably be a much more enjoyable experience than developing for the PS3.
Except Microsoft has yet to port Virtual PC to 64-bit PowerPC chips. The biggest issue is that the POWER derived chips are big-endian only. VirtualPC on the 32-bit PowerPC chips just has the PowerPC run in little-endian mode.
G5s are based on the IBM 64-bit POWER architecture. Which doesn't support little endian. So that's why the G5s don't support it. But the 32-bit PPC chips that IBM and Motorola shared do.
Microsoft can use their virtual pc technology to run the x86 instructions on the PowerPC architecture. However, if the PowerPC processor they are using from IBM is based on the POWER architecture, they'll lack the ability to run in big-endian. VPC is supposed to support the G5s later this year. So it's not out the realm of possibility.
Remember, Nintendo generally doesn't have backwards compatibility. Breaking compatibility would allow them the flexibility of changing their controller as well.
If you are feeling lazy, the proper abbreviation is PCIe.

You can turn the watermark off, even on the free version. It does it to tell the person that it is being used to play the file. If you use DivX to decode XviD files you'll get that watermark, and yes you can get DivX to not play XviD.

Pascal FTW!
Not very useful, but it combines allows students from shooting themselves in the foot, yet allows it when it's required.
Maybe Microsoft will release updated virus definitions once a month too.

Worked fine here. Of course I have a completely fresh install of 1.5.
They have 8 gb ipod mini will probably arrive at the same time, since the harddrive of that size has been available for a few months now.
Maybe we'll see 1 and 4Gb Shuffle, 6 and 8Gb Mini.

The system running the Intel Linux and Windows is an i5 520, that's not the same system as an OpenPower 710. iSeries servers have optional integrated Intel servers http://www-1.ibm.com/servers/eserver/iseries/integ ratedxseries/
Other than generics, and static imports, all the new language features of Java 1.5 aka 5.0 were available in C# 1.0. There was even a slashdot story about it. http://it.slashdot.org/article.pl?sid=04/10/11/145 4220&tid=108&tid=8/

Seems the CPL is popular these days. Even Microsoft uses it for their opensource projects (WiX and WTL). Not to mention IBM who is the CPL author.
