Thought of it as well -- but the software would have to be more evolved (2D autocorreleation) rather than performing simple accumulation/averaging and shooting for "white" instead of "black".
The F-117 lost in the Balkans was purely luck; they knew the plane was overhead, but couldn't detect it, so they just started throwing everything they had into the air, much like over Baghdad during the Gulf War.
It was not _pure_ luck, from what I've heard -- US pilots and mission planners were so SURE that it is "invisible" that it ran the same route day after day. And, of course, given enough time even very small signals can be detected over averaged-out noise... They knew when and where it was coming and were shooting for it.
Of course it does not beat using $100 microwave ovens with broken door block to lure $1,000,000 anti radar station missiles...
Why, yes, I WAS trained as a Soviet air-defence officer!;-)
Actually, there were both, though the 'out' one was the title of the song, but "is there anybody IN there" was also mentioned in slightly different context... happy hunting!;-)
It is silly to ask this question over here, EXCEPT for the case when it is fishing for the interesting answer to some completely unrelated question, like, "How's computer security in your DoD-approved location is done?".
No, I've never had a clearance (though worked in a place where I'd need one to advance any further) -- and I do know that on the "dark" side of the network they did not use Wintel, they used DEC...;-)
... I've had good success at archiving all my previous department's e-mails (actually, what we were calling "e-mail journals") using Zope and a tiny product on top of that called MailBoxer. Provides nice web-brouseable/searchable interface to the archives, and Zope can be extended via python to do what you want to do.
Yeah, BUT what if you just want to A) Take some S-parameters and B) import them into Spectre/ADS/(God forbid!) Excel? No, I'm personally NOT writing the whole simulation engine (or even the frequency domain part of that) in LabVIEW!;-)
Of course you can tell me that I can access instruments (at least Agilent ones) from ADS via their whatever the name link (running over GPIB), but, however overpaid I was, it was still cheaper for me to haul the floppy rather than find Sun-supported GPIB card...
A $500,000 65 GHz network analyser/BERT tester/whatever high-end RF equipment would allow you to either 1) save data to a floppy or 2) print to a (Centronix-connected) printer or 3) yeah, get data over GPIB, if you write a program/.vi to do that.
So, I guess, the floppies are here to stay -- I know that my company-issued laptop had one BECAUSE I had to transfer data to/from those beasts.
I know, I know... Actually "in Soviet Russia" it WAS practically illegal to participate in martial arts training (I did, we had to make sure that the door to the school gym is bolted before starting the routine -- of course the trainer would have to deal with most of the problems). And I can understand (now) some of the reasons why a teacher would dispense some punishment for both parties -- but not anything getting to the felony level, dammit!!!
Funny thing is the same thing is said for violating a school's drug policy or violence policy. And I'd fully expect criminal charges in either of those cases.
What the heck is "violence policy" and how it is different in the US schools from "the laws of the land"? Is it something like a Catholic school punishing a student for not turning his other cheek when hit in the first one?;-)
Seriously, the more stories like this I read, the more sorry I feel for the kids in the US public school system. No, never been in one, got my schooling "in Soviet Russia" and even there (and then, late 70s-early 80s) they would let parents give the punishment for something as harmless as this, not the federal penal system!
NAME
mlock - disable paging for some parts of memory
SYNOPSIS
#include
int mlock(const void *addr, size_t len);
DESCRIPTION
mlock disables paging for the memory in the range starting at addr with
length len bytes. All pages which contain a part of the specified mem-
ory range are guaranteed be resident in RAM when the mlock system call
returns successfully...
Do not tell me that Windows does not have anything similar! Though maybe it does not...
... that NSA would be interested in teraFLops? Last time I checked, their kind of processing required manipulating bits (in weird ways), not imprecise floating point numbers. Go to DOE to pay for FLOPS...
(least-squares solution, that is), probably the best resource is "Numerical Recipes", they have been changing their location for as long as I remember, but Goodle says it is currently at http://www.nr.com/
I remember dealing with that particualr issue myself...;-)
You can get an evalkit from anyone of top FPGA vendors for a $hundred or two (for example), program it in VHDL (if you were doing software for a while it will be quite easy for you, just another language -- actually if you've ever done Ada it will be very easy, it is basically the same), compile VHDL program, load it into the board (they come with USB, parallel or plain old serial links) -- and here is your first special-purpoise hardware device!;-)
Now, the problem is to figure out what do you want it to do....;-)
The 3.5- by 8-inch template resembles an IBM punch card, with eight holes arranged so their position relative to one another describes a unique identification number in a proprietary code.
Though maybe after this/. article there will be a huge underground movement to break The Code -- (the "Da Vinci" part semi-assumed;-) )

It uses a hand-written context-free grammar to form all elements of the papers.
I know you were aiming for funny, but there is a big difference between following a hand-written grammar and deducing it from the text...

No, really!

the interesting answer to some completely
unrelated question, like, "How's computer
security in your DoD-approved location is
done?".

that basically says "We don't find anything wrong with that content"...

The entire world becomes depressed, due to the absence on natural light, kills themselves or simply stop having sex.

YOU stop having sex BECAUSE it is too DARK??? Hmmm... You are such a minority!
