There are many good papers on this.. I particularly like the one on "AudioDNA" visit your local google. You see with Audio Fingering Printing we are actually able to take a song that has been rerecorded onto an analog tape, slightly time stretched and still be able to tell that its the original song. It doesn't rely on bytes, but instead qualities of the audio signal.
There are many ways to do this, but one solid method is to analysis the audio signal for acoustic events that are resistant to change. Make a listing of these events and store there locations in time as a chain. Even if you only have a small segment of the chain you can search for it with techniques similar to the one's they use in biology (nobody looks for a complete DNA chain). Its a little difficult to explain without knowing something about signal processing so I suggest just searching the web. Here are a few good topics:

I have a 12in powerbook and originally I would have thought something like a water cooling system would be nice, but that would limit my many discovered extended capabilities for my laptop. You see during the winter I use my laptop as the furnace for my apartment building (I live in Montreal, Quebec.. You can imagine it gets pretty cold). It was however becoming a real problem this summer as it got so hot as to melt through to the basement level of my building. My landlord was in the process of drawing up a lawsuit, but then I discovered an alternative to simple water cooling that I think should be considered by enlarge by the geek community.
12in powerbook hydro electric plant! Disregarding the fundamental laws of thermodynamics I have managed to use my 12in heat plant as a tool to turn great amounts of water into steam. Believe it or not, I'm actually powering the entire of Centre-Ville on just my laptop. The city since has graciously agreed to pay my landlord for all damages. Combine that with my cold-fusion dock bookends and I think the energy crisis is over.
But seriously folks... I can't believe how hot laptops and computers are running these days. It really is enough to keep a room warm without a heater. Is water cooling the future or just cooler processors?

You can sue over basically anything. They could bring them to court simply to say they thought their assertion of demands/requests resembled black mail. They have the weight/money/political connections to bring a very trivial detail into the court room.
You should never challenge a powerful company like this. Have a lawyer draft up all communications, keep complete records of all activies and communications within the group, and do not volunteer any information without council present.
Having help doesn't make you look guilty, it makes you look prepared and intellegent. The way these guys handled their communications (spelling errors and all) makes them look like out of control destructive teenagers.
It seems we've had a lot of false and misinterpreted information about this team and their exploit. I don't have an x-box and only somewhat understand why their exploit would work (integer underflow..?), but it atleast sounds interesting.

As far as the team... I think they should have submitted their findings to a legal firm of some kind instead of this not-so-holy covert behavior. Their behavior will only lead to troubles in court.

Re:Do younger minds absorb quicker?

I'm a piano teacher, and a computer scientist.
For the most part younger kids learn piano better simply because they put in the time and are willing try new things. My adult students often progress much faster than my younger students. Its only that most adults also have complex lifes already and can't put in the time a little kid can. My adult students that have trouble tend to do so because they are afraid of the piano. I must admit, however, that some young minds can simply make unbelivable progress for no single reason other than natural talent.
I think the same thing transfers to Computer Science. For the most part if you have used computers for years you are not afraid to try things. Many adults are very afraid of computers. Kids simply explore and enjoy them.
I think Gen X'ers get the rotten deal in all of this. The generation before them WAS worse at computers at an old age. This is no longer true since many Gen X'ers have had computers since Commodore 64 or earlier. It will take another generation before this is ammended.
And for all of you programming divas just realize that programming isn't a "god given talent" and neither is piano. You simply put in the work, do what you love, and good things come from it. Don't think you are special for it, because no matter how good you are there will always be an 11 year old asian girl who is better than you'll ever be.
I have an Apple 12 in Powerbook. I can recommend it without hesitation for most use.
It has the advantage of being very portable, and will allow for most things you would need at a school. It can use common college things like Microsoft Word, but its also a great portable UNIX-like box.
Basically it allows me to do everything I would with a PC, but also lets me use software that is traditionally MAC like MAX/MSP and Peak.
Only disadvantage is alitte expensive and alittle hot.
Nobody will read this because I didn't post it in the first 12 seconds the article it up but I'll post anyways.
I'm an American from near Chicago IL, but I live in Montreal QC (that's in Canada) completely without at car. The reason I can do this is that the transit and services is setup to let me do this. The metro/bus system is reliable and affordable, and taxis are plentiful and decently priced. If I want groceries I either carry them with me or I can have them delivered to my apartment by any number of grocery stores.
At home, however...
Its HELL. You can't go anywhere without a car. Everything is spread very far apart because either it was built during the "hack and slash" all I want is land years, or because it was easier to put a super-megalo-gigantico mart. These ultra-shops are so big you almost need a car to go through them. It takes forever to get what you actually want, and the service/quality stinks.
The US has simply built cities that are too spread apart. For a nice urban environment you need things less spread apart, with adequate services and clean transportation.
I will only get a car again if I absolutly have to. Otherwise I will rent for vacations.
Ignoring the parent comparining the cost and the fact that I'm for free software...
The reason this is different than selling a car manual is that you are not moding your car to run equipment without paying for it or that is restricted for any reasons. If a car manual instructed people how to get military gps coordinates or pick up restricted broadcasts, you can bet it wouldn't be on store shelves.

There is actually a lot of research in video analysis right now. Yes it is tough, but there are lots of tricks and a growing and fun community!
If you are a windows user I suggest trying eyesweb (www.eyesweb.org). Sorry, it works alittle better if you use PAL and I don't like Windows, but its open source and flexible.
The only problem, is its a KILLER on the CPU. The more analysis you do the more research you need. For face info, check out blob analysis and a head set camera.
If you want to know more you can send me a message.
$0.99 USD Is too pricy. It is more than the cost of the average cd and the AAC encoding is a lossy format. Perhaps if they offer better deals on albums or bulk songs this is a good deal. As it stands, music is too expensive already.
This looks like a nice stand politically, but its really just a chance to gouge the consumer market as the first big dog in.
Besides, I'm of the, "Go to my concert, I'll give you the CD" philosophy.
I have noticed a performance increase when I have a seperate hard disk or partition for my operating system/programs. It seems to me that a lot of geeks do this. Have a fast hard disk for applications and a slower bigger hard disk for data. Memory is cheap enough now that I don't often even need to use virtual memory. I find the only time I need more system memory is for real time video processing. I don't even need it for audio anymore.
Wouldn't there be some benefit in having about 2 gigs of memory just for running the operating system and a seperate/cheaper storage for your large files? I seem to recall google running everything on DRAM.
Could someone explain to me why we don't have a portion of non-volitle memory for our operating system/programs?
I've used a lot of software developed by IRCAM, CCRMA etc. The only thing I fear is reliability. jMax (a Max FTS/MSP/PD whatever you want to call it) used on Linux is insanely buggy. Its a cool program and obviously the people at IRCAM are qualified to make it, but by the time you finally have it configured, it becomes extremly unstable.
For all sound development I end up using an Apple. I'd like to use other varients, but I've just not had the same stability.
Same price as an already overpriced CD and you get less quality.
Let me give you a little analogy: I can go a whole day without water, but periodically I get thirsty. In the past, I could stop in any store and get myself some free filtered water (thanks to the goverment for providing cheap filtered water). The stores knew that they made their money doing other things and that giving away free water was both a decent thing to do and a good way to gain people's trust.
These days, I almost always have to buy water. Many places have gone so far as to remove drinking fountains and put in soda machines. The machines may not even have water, but if they do, it will cost the same price as the soda. Of course the soda is an addictive stimulant and when put next to each other people often choose to go with their addiction.
Music is very similar. Although I'm sure some people can go a day without music, I find that its a very important part of my soul. Mind you as a musician I create most of my music and pay to do so (instrument, sheet music, etc). All I want from the public is to help me to play by comming to hear me play and supporting me in other ways if need be. I can't play a concert everyday, and I want people to have access to music when they want. For this I create a CD that let's you get to know me, and I put into it the highest quality possible. Hopefully you'll come to my concert now, maybe buy some sheet music, ask me to teach a lesson... But someone else has decided to sell you a lower quality recording of my art for the price of a bottle of water. I can't control what gets to you, because someone else get's to distribute when, where, and how my recording is played.
You'll probably go get some coke, because really water may be good for you and your soul, but coke is cheaper, addictive, and that is what they want you to buy.
