If by cross product you mean a bilinear map (a,b)-> a x b on some vector space where the product is orthogonal to the arguments and |a x b|^2+(a.b)^2=|a|^2|b|^2 then you may be surprised to hear that there are many cross products in dimension 7. They come from the octonions, the non-associative 8D generalisation of the quaternions. See here.
I take back what I said about a scam. I had a look at the abstract of the poster on the web site. This is just a poster. This is no giant research project, it's just someone who's had the initiative to do a nice little analysis of old data and put up a poster about it at a conference. They're not making wild claims and all that's available online is an abstract. This is about as far from publication as you can get. This is truly terrible reporting by the news agencies.
I've always wondered where those arch-villains get their gear like luxury underwater bases and industrial installations in the middle of volcanoes. Well now I know. And at $78,000,000 I'm just going to have to turn to a life of crime. Maybe I'll become an accountant.
Looking for a particular spectral signature probably just means looking for pixels with RGB in a certain domain. Maybe they have some other channels too: IR and UV from detectors alongside the camera (that might explain the 'image registration' issues), so they're looking at multispectral images. Either way: extraordinary claims require extraordinary evidence and pixels of a particular colour are barely even interesting - let alone extraordinary. Sounds like yet another scam to get funding to me.
That copyright just so happens to have a dollar value
That is a largely arbitrary number. If I fail to sell a product for $10000? because it's overpriced and then someone copies it illegally are they stealing something that has a value of $10,000? (1) I don't think so and (2) nobody has actually lost that money.
I'm sure you're making a good point and that I'm misunderstanding it.
What do you mean they lose billions of dollars? In order to lose something you must have it. If you don't have it you can't lose it. The billions you claim software companies lose is a fictional construct - it's the extra amount of money companies claim they would make if some hypothetical (but impossible) scenario were true. Well it's not true, and never will be true, so it seems unreasonable to claim that these billions are lost.
Unless you're claiming that every time someone copies a $100 CDROM the company that produced it originally is losing $100. That would be a very silly claim.
It's not a claim that these people were unintelligent. But techniques like representative art are a learnt skill. All through life we discover things that seem obvious after the fact but aren't so obvious a priori. Representative art is one of these. Even recognising art as a representation of something is a learnt skill.
Humans are more than just their physical bodies - they are the products of a culture and those cultures have changed dramatically over 5000 years.
BTW There's every reason to believe that these people were illiterate if not exactly monkeys. Just because some people in Sumeria or Egypt had got the hang of writing it doesn't mean that the Irish did too.
...they try to make up cryptosystems for themselves. A small minority come up with good ones. The rest of us tend to frequently come up with the same unreliable schemes. Funnily enough the system described by the article seems like one of these codes - it even has the same bullshit that beginning students will come up with to justify why their code is good.
Whatever the merits of this code - by definition it ain't a one time pad!
I'm hoping that they pull their fingers out and get down to work on the optimisation. I hope they haven't got the transparency routines running the whole time when I have no transparency anywhere on the screen. But anyway...the problem must be more fundamental: a slow PC can render pdf files much faster. Rendering PDF files requires many of the fancy features that Quartz supports. And this doesn't use PC hardware (as far as I know). As far as I can see the Quartz renderer must simply be badly written.
Unfortunately, though not using X11 should result in a major performance increase, Aqua isn't any better. Even viewing pdfs (which MacOS X renders natively) is painfully slow. Try resizing a window under MacOS X next time you're by one and see how it performs.
G4 PowerBook 550MHz. Latest OS, latest DVD player. I did some research on the web: the problem of having to reboot to eject a disk seems to be a standard problem. Some disks (including DVDs, CD-Rs and CDs) seem to slip by without the OS noticing. And if the OS doesn't notice they exist then there's nothing you can do to eject it.
One DVD I can't play at all is Gladiator. Plays fine on my PS2 and it looks free of scratches (it's hardly used). I have another DVD whose menu looks corrupted. It took several attempts to get it to recognise "The Dish". I was watching "Brainstorm" the other day. I stopped it and restarted it and the video stuttered badly and the audio had gone. I hat to quit and restart the player. I have a lot of trouble with CD-Rs not being recognised although I've had no hassle with CD-RWs (probably just chance).
And several times the Finder has just 'gone away' and killing it didn't seem to do anything.
Still - I've had no problems for the last week apart from the "Brainstorm" one.
I love MacOS X - but like the real thing it's not a painless relationship!
I was hoping that one year on they would have sorted out the stability issues. I have used many Unices in my life: Irix, SunOS, NeXT, Linux, *BSD but MacOS X is probably the least reliable (apart from Irix on the O2 in its later years). To still be in this position after a year is a little shameful. I have certainly had major problems while watching DVDs (major DVD slowdowns and loss of audio, failure to detect a DVD, inability to play some DVDs and inability to eject DVDs (requiring a reboot!)) among other things. What's particularly shameful is that it's less reliable than Windows 2000 which is the OS I chose to reject in favour of MacOS X.
I still love my PowerBook but it really is painful each time I have a kernel panic or it 'goes away' never to respond until I reboot.
...I had to put up with the humiliation of having my brain forcibly removed. After all - it's a lethal weapon. I can design bombs with it, I can think unpatriotic thoughts, I can even memorize tunes that have a copyright. My brain was a terrible thing and it ought to have been removed. Everyone else should submit to having their brains removed too and the world will be a much better place. Except politicans of course - there's no need to have their brains removed.
There's nothing special about it. Pour enough liquid at 100C on yourself and that's what you get. I make my tea the British way - I boil the water. I warm the teapot before pouring the water in so it doesn't lose heat. I like to serve it so that it's too hot to drink at the first sip. I guess I come from a different culture. If Brits made their tea disgustingly with lukewarm water they'd probably be surprised to get scalded by a hot drink too.
Do you routinely assume that beverages served to you for your consumption are capable of inflicting full-thickness third-degree burns in 2-7 seconds should they touch your skin?
Yes. I have always made that assumption. I think I learnt it at a very young age - probably when my age still had single digits. It seems my belief system is well adapted to the world I live in. You may find that you need to adjust yours.
No, but in a format that is used mainly to render monochrome text it makes sense to optimise your code to deal with that fast. And given that G4's have a velocity engine 4 colour channels can be handled simultaneously.
My G4 has 0.5Gb of RAM - so no excuses there!
Here's my biggest complaint about my G4...

...Powerbook (550MHz). I have no prior experience of Apples and one thing I was looking forward to was having lots of pdf documents collected together that I could read on the go. I hear that PDF is native to MacOS X and I get excited about it.
So I run the previewer. Guess what? It takes about a second to render a page. Well...sometimes it's about a half. I try acrobat reader. Even slower! Come on Apple. When I used to use a NeXT running at 40MHz I could read postscript documents at this kind of speed. It's inexcusibly and unforgivably slow. On a 500MHz pentium I can drag PDF documents up and down the screen at about 10-15 fps. It's just like having a paper document that I can scan up and down. But un a supposedly more powerful machine on which PDF is native it's about 5-10 times slower. This is truly pathetic. This is 2d graphics. It's barely a million monochrome pixels that need rendering. What's the CPU doing for all this time? Am I really going to have to write my own PDF viewer?
They do metaphorically. When discussing evolution the intentionality metaphor is a pretty powerful one and making deductions via the use of such a metaphor often gets you the same results as making a literal argument except in the former case it's easier to think about because humans seem to be particularly good at making arguments about intentions.

Not to mention the bikinis for the harem arch-villains always seem to have.

Do you work in an office? If you do, how do your neighbours feel about Speakable Items? I've tried it once - too embarassing!

Now that would be an interesting story.
...a web site that has a fancy looking shockwave (or whatever) animation is a front for a scam? Or is it just true sometimes

It might not be useful to you. But can you speak for the needs of everyone in the world out there who needs to send information securely?
Whatever the merits of this code - by definition it ain't a one time pad!

Aqua is nice. But it's certainly not fast.

You mean like Fabtek's Work Boy? Frommer's also did an organizer - do a web search to see the ROMs (don't use them of course - that's illegal).
Yes. I have always made that assumption. I think I learnt it at a very young age - probably when my age still had single digits. It seems my belief system is well adapted to the world I live in. You may find that you need to adjust yours.
