... but "Something Wicked This Way Comes" is one of my favorite, most enjoyed influences in terms of writing style and pure entertainment. I've read many of his other stories (and I agree with some that "Fahrenheit 451" isn't one of his better works, though it's undeniably important), and enjoyed them all.
However---and perhaps it's the time in my life that I read it---for pure *joy* at the written word and how he wields them, "SWTWC" is probably in the top five works which has most affected me (and this post is no, nor is it meant to be, reflection of Ray's abilities).
Ayn low-priced offering from Acer (or Dell, or whevever) onto which one installs any recentish linux or BSD. All (and more) of the screen and ability are there. I must admit that the style may be lacking.
I see you're actually an experienced programmer and not a recent graduate. How do I know this? I see no mention whatsoever of "comments" or "documentation". Commendable!
They probably don't avoid it. On the order of 10^5 cross-correlations can be done on medium-res pictures per second with a fast machine, especially one with dedicated video hardware. They might drastically narrow their search space by having a library of perhaps 100 "basis set" or "canonical" pictures (faces, cityscapes, mountainscapes, ocean photos, animals, etc.) with varying colors and features which stand out, and do the first set of correlations with those. Depending on which of the basis set the target image correlates best with, they can then quickly narrow down the next set of correlations.
You can probably tell I'm totally guessing. But I'm working on a somewhat similar project myself, and that's our first step.
It's surely closer to cross correlation, meaning it's nothing like comparing pixel values but more like correlating the image's space-frequency components.
It almost certainly just IS cross-correlation, with a little algorithm to find the correlation maximum somewhere near the middle of the picture. This, of course, is simply another way of comparing pixel values. It's probably much, much faster, because so many established FFT algorithms exist for very fast multiplication-and-add operations, but it's essentially just pixel comparison.
Sweet! I want to get me some of those 84 minute hours like they have in Australia!
P.S. I think you should volunteer your mathematical abilities to the teams.

Thank you. I understand (no likey!) it now.
Nice review, but I don't understand something.

I may even buy the book based on the review.
Leaving aside stuff like not for the feint of heart, which is just poor editing, what the hell does I found Chapter 11 to be very useful (pun intended) mean?
Maybe it's the ultimate meta-pun, where there was no pun in the first place, but the author pointed out that one was intended, so one was slipstreamed into the statement.
You're right -- I was too hyperbolic in my skepticism. I'm just tired of the wild speculations, just about every year since Pendry et. al started up Veselago's prognotication in earnest using metamaterials. The press has a field day several times a year, and the scientists either haven't said anything serious about cloaking technology, or they're feeding the speculation just for fun. It's been done to death.
This was posted in Pharyngula yesterday. The usual prescient commenters noted that nowhere on the researchers' pages was there active speculation about an "invisibility cloak", and it was probably just some reporters going wacky over the possibilities. http://scienceblogs.com/pharyngula/2008/08/get_your_invisibility_cloak_he.php
It's still based on compression (and out of Penn State, licensed to Ben and Jerry's, of course), but it's a much *faster* compression, at the frequency of the sound waves used, and it takes advantage of air's intrinsic nonlinearity at high acoustic amplitudes, rather than the much slower effects inherent in traditional refrigeration techniques.

Wow. That's like a story, all about how your life got flip-turned upside down....

Psst. At least it's red!
Can you create a filesystem in the time it typically takes to create or delete a folder?
Can you take snapshots and/or clones, quickly, so that one always has a history of each and every file on disk, and easily accessible?
Can you create automatically-expanding storage pools?

Long answer: Fuck no.

In other words, this speed increase could enable the drive to do 10% more random I/Os per second.
We at the NSA are interested in things which are more random, and would like to subscribe to your newsletter.
At least do a simulated dist-upgrade by using the -s switch before doing the "real" one!
apt-get -s dist-upgrade
Sometimes, just sometimes, it'll catch things which might go wrong before they actually happen.

Actually, that office buys computers from 17-year-old boys. That's not glue.
I know I fail to learn from my mistakes.
I forget to take out the trash.
I'm told about it.
I forget again.
What's my problem??
Living with someone who tells you to take out the trash?

Hahaha! Ah, Mr. Schwantz, you're so naive! I repeatedly touched your wiener just now. Your tests show nothing.
Definitely, definitely.
I don't know. I have it blocked with NoScript. Is there a reason I shouldn't be blocking it?
...that posting such a story will inspire lots of slashdotters to go download or access Google Earth, and cause electrical problems.
