If not for better quality per disc.. It would certainly help to have more minutes playtime at equal quality, wouldn't it? After all, VCD films come on two discs because MPEG-1 can't fit more than ~60 minutes on each.
> No its not PRACTICAL...but maybe they've got some brute force per song?
They'd need A LOT of brute force. Still today exist no two known files with same MD5 hash. You could claim the big price if you could come up with two such files!
At least they try to keep power uninterrupted even during minor nuissances like heat development.. Isn't that what we expect from a REALLY uninterruptable power supply?
If gravity "waves" would propagate faster than light (or instantly), it would be possible to communicate faster than light (or instantly). Sure, earth is small compared to the speed of light, but even here on earth you notice half-a-second of delay for example in an overseas telefone call due to the speed of light (and 36kkm geostationary orbit of satelites). It would certainly be a win to overcome the speed of light in communication systems, for example when remote-controlling a mars explorer robot (where interactivity is completely absent). Not even to mention realtime communication with alien races.. So unfortunately, gravity is not faster than light. Sorry.
Wow, they are going to distribute "$75,700,000 worth of prerecorded music compact discs" to "not-for-profit, charitable, governmental or public entities". That's really worth signing up on their web page..... Remindes me of Microsofts offer to donatie software "equivalent" to umpteen-million-dollars to buy them free from court. I wish MY company could pay its expenses (and tax) in goods rather than real money.
> The XBox2 would 1)check if it's an XB1 or XB2 game, then 2) use the appropriate key.
So the obvious crack is to toggle the version number of a game to XB1, and re-sign it with the (then known) XB1 key. Maybe a wrapper will be required, too, to enable XB2 features on the OS/HW that might have been disabled, after the game has been detected as XB1 (to prevent this type of crack). The modified games can be distributed as ISO images, ready to burn.

There is another difference between "Authoring" and "Consumer" as well. It has a different surface coating and is written with a slightly different laser frequency. So you can write a logically 100% correct DVD with decryption key area, but it won't play in "consumer" players for physical reasons. Much like CD-RWs don't play in old CD players.

The train does not travel at ground level. It is elevated by some 5 or 8 meters. You can see it here on these amateur fotos of the test-track in Germany:
Unless cows learn to climb, there won't be more problems than birds and human attacks. Hmm, at least in Germany - in some areas of China live monkeys, don't they?
My favourite is Perry Rhodan. Perry Rhodan is published on a weekly basis, with about 60 pages per week. The team consists of about 6-8 authors and is located in Germany. The first issue came out in the 1960s, and the story begins with Perry being an american astronaut flying to the moon. From then on, the story diverges from reality as it turned out 1969.. Perry Rhodan discovered a stranded alien spaceship on the moon. The US/Russian/Chinese powers on earth want to get ahold of the alien technology, but Rhodan understands to use it to unite them (after quite a while). Mankind starts to explore the universe and still does today.
Published since about 40 years, Perry Rhodan today consists of almost 2200 episodes. There were translations in more than 20 languages, but popularity varied over those 40 years and I'm not aware of many translations still being done today. If you understand German, Perry is for you!
The nice thing with it is that the authors try to be consistent within the "Perry Rhodan universe". They extrapolated imaginary physics from what was known at the point of writing. And from then on, they stick with the rules. Except for some minor errors, it is very consistent.
Apart from the 2200 episodes (60 pages each), they were re-published as book ("Silberbände"). Each book combines about 10 episodes and has been refined to provide more fluent reading (each episode was written by a different author of the team, to keep up with the weekly publishing deadline).
If you have EMULE or EDONKEY installed, give it a try with "Rhodan" as search word. Most of it is available as ebook.
Thanks for this hint. The screen display is english now, but unfortunately the default search space is set to "english, spanish" instead of "all languages". Better than "spanish only", but still not the real beef.
For quite a while, Googles ranking system could be "cheated" by supplying links in usenet postings. I had a link to my page in my usenet signature for a few weeks, and it became #1 although the page was an excellent example of how to design a page NOT to be found by search engines.
I live in Spain, but barely speak spanish. However, "www.altavista.com" detects my IP and forces me over to "es.altavista.com" which
a) has the screen mask translated to spanish, and
b) defaults to find only spanish content.
This is annoying, because there are not many spanish documents about embedded software development, and those few that exist are very difficult for me to read.
I won't give AV a chance, for this very reason. The necessity to configure the search engine again and again is just too inconvenient. Google is so much easier to use.
Ok, now that we learned that at L4 / L5 there is a natural equilibrium which keeps a space station in-place - has anyone been there? Wouldn't it be a logical conclusion that a lot of dust, rocks or other stuff is hanging there, kept in-place by the equilibrium of L4 / L5?
> So if I want to manipulate court evidence, what's stopping me from taking a *screenshot* of the image on screen, manipulating that image, and then re-encoding the hidden data so it appears no editing has taken place?
The encoded data is a digital signature of the rest of the picture (everything except those bit "slots" that the signature will be stored in). If you move this signature to another picture, it will fail the signature verificaion. The court can extract the signature allright but it does not match the pictures' (visible) content.
There is another problem though: hackers might extract the secret signing key from the digital camera (maybe as easy as downloading the latest firmware flash upgrade from the manufacturers support web site). With this key, they can sign any picture, even your photo-of-a-photo.
The signature mechanism would have to be tamper-proof, for example with a security smart card and other measures. This is a complex problem, by far more complex actually than the "how to embedd the signature into the picture" thing.

Cards avoid use of the AGP bus bandwidth as much as possible, by supplying on-board RAM. Stuff is uploaded once, and then used many times. Todays cards offer 64 or 128 MB for this purpose.
Unless texture size or level size grows dramatically, the AGP bus bandwidth suffices. In Q3A for example, level textures are uploaded during map-changes, and from then on only T&L data travels through the AGP bus.
So... We're gonna use P2P sharing tools to distribute content after DRM has been cracked away from it, and Palladium will make sure that all those no-upload patches won't work anymore and every leecher really is an uploader too!
> I believe using headphones would defeat the purpose of the technology, unless of course > you had a 5 channel headphone ring around your head.
Although a human has only two ears, she can very well locate sounds in more detail than just leftright. This is due to the particular shape of the ear. There are several different paths for the sound to take, with different length. As result, the very same sound hits the ear drum several times shortly after each other. Our brain uses this information to reconstruct depth information and gives us a good idea about where in 2D space the sound originated.
Note that I say 2D, because 3D would actually include the height axis and although "3D sound" is a good marketing buzzword for 3D games but in reality humans are very poor when it comes to locating sounds in full 3D. It's simply not part of our every day experience and thus we didn't develop any special skills for it.
But back to the topic: headphones are a very good and cheap way to reproduce 2D sound, simply by generating the overlapping mirror images of the original sound in software. The ear/brain is tricked into thinking that the distortions are caused by the ears' shape. As result, the sound is "placed" in the 2D range.
3D games like Q3A and UT do this in software, and you can experience so-called "3D sound" with any cheap headphone. No 5 channels required!

Well, with a meter you can measure inches and feet.
