if you read the article, down at the ^2, theres a statement that 'Home network file transfers, analog recording of LPs, cassettes, etc., and S-Link changer control will be available via a free, automatic upgrade available in the near future.' Translation: If it works, you'll get it, and we'll update your software without telling you:)
Well, lessee- do I think IT is undervalued? Depends. They make me call tech support for stupid reasons that I ought to be able to change, I can't install fonts, etc.
When I called for a fun question, just once, I asked if PCs were Big Endian or Little Endian. I've never had a ticket escalated so fast- none knew the answer. In fact, I ended up calling a chemist that programmed and he knew the answer.
Don't mention the word 'server'. If you do they descend upon you like the rightous going to protest an Eminem concert. Dont' expect more than 50 megs of disk space on the server- drives are too expensive (note one particular one contains all the research material has faild 4x... they haven't fixed the problems yet).
No I don't have a good attitude towards my IT dept. It's called Feudalism, they are building a kingdom and all the little serfs have to run around and do their bidding. They upgrade your computer to untested software and then blame users for crashing it and bringing down servers
So is IT undervalued? Nope. Overvalued. Reign them in and see the company take off... give them free Reign and watch them grind research to a halt.
I bought a GE dvd player a few years ago, and the movie "Scary Movie" takes 30 minutes to get past the FBI warning. So how lazy does that make me when I can't forward, skip, move, scene select, or ANYTHING around that stupid damn FBI Warning? And no, the store wouldn't take it back either (because it was opened).
First off- I do know what I'm talking about How is 'remastering' an image that is shot on 35mm film improve when you blow it up to 70mm? I mean, realistically, what this is saying is that you don't need to ever shoot 4x5 cameras- just shoot 35mm and all that precious details will magically come out when you digitize it. Poor Ansel Adams- if he had been alive now he could just use his $35 disposable camera and get those huge blowups with startling detail
OK I think you've caught the drift. Film has a limited resolution. Original IMAX uses 70mm film to get 4x the negative area (hence they can resolve quite a bit more detail than standard film). The only advantage I see to this is the marketing ploy- Genuine IMAX Film SIZE!. You don't gain detail, you don't gain ANYTHING that isn't already on the film. And since you are starting off on a small format to begin with, its not going to get better. Now don't get me wrong, you can improve some work with digital sharpening and whatnot- going to a larger format helps there. But it in't going to give you the same quality of an IMAX experience compared with a film that is 70mm. It just can't be done. See my earlier jibes about 4x5 cameras if you need further humour;)
In Scientist-speak, the word 'suggest' is synonymous with "is" or "state". But you don't publish like that. Publishing is done so that you do not appear 'too wrong' in the future.... go back and read some journal articles from the 50s:) Very important but very lax in thrust.
Problem is, you've been diluted by too much modern media where they state with '100% certainty' and when wrong say simply 'oops'.
Yeah, right. Want to make a few million compounds just to figure out what their absorbance spectra is? How about trying to figure out where to add an atom or two to change the colour of the compound?
Computational chemistry is a very important and powerful field. Simulation and modeling of quantumn calculations save millions of dollars
Haven't you heard of 'folding@home'?
What happens if you cross a chicken virus with a human virus?
You get the next plague.
Those that understand my comments will remember the China scare from 2 years ago. Those that don't will think this is offtopic.
Just because the virus doesn't reproduce doesn't mean it can't transfer it's genetic payload to something that does.
OK how do you back up your photos? How do you keep track of your backups? You want to explain that to your mother?
"Ok Mom, here's what you do. Get your last CD and compare the file stamp on it to the files on your HD. Copy anything that is newer into a temporary folder. Then fire up the burner program and copy those files into the.... what? yes.... I'll come home for dinner".
No, until it's automated backup/automated recovery, it's gonna be a pain in the ass for anyone.
Most systems have 1 hd 1 cdrom. If you're lucky it has a burner.
This has been bantered about by practically everyone in any sort of media outlet. You've got librarians trying to figure out how to store all of the supposed 'research' that exists out here. Journals are going out of print because they can publish faster and easier on the web.
You've got photojournalism people shooting digital because it's faster and offers some image structure advantages at high speed- no negatives to keep around for a 50 year retrospective.
And finally, you'll have the home consumer trying to back up all his photos to CD, organize them, and get thru the thousands upon thousands (note- most neg drawers aren't well organized either, but... ) of images that are labeled DCP_00389 or some otherwise useless name.
And then the hard drive crashes
And then it's gone.
Nothing will change until this starts happening. Give it 3 to 5 years, or however long it takes joe and Jane to upgrade their computers and start losing stuff. Then some sense will get back into the world;P
The DLink Gigabit ethernet cards I threw into the small file storage machine that hangs off of my computer don't care what cable you stick in them. As long as the wires come out, it figures out what's the correct 'routing' - crossover or regular.
So does that mean my $99 Gigabit Ethernet Card is at least as special as your $3000 Mac?:P
- and found it to be an incredible codec. Some of the really really neat features are 'streamable' files- want a thumbnail? Yank off the first 1k of the file. Want an 8x10? Grab the next 500K. Want the full thing? Pull the remaining chunk.
Better still, you can 'order' the file- give an 8x10 as only 30% quality, which is quite good, with the first 10% of the file... or stream a bit more and get better quality. IE the more you can afford to wait, the better the image will look.
Of course there's also the compression and support for large coulor spaces (do we have to talk about file formats and function again?:P), not to mention a more robust error handling and inclusion of data to tell if you 'cropped' a file
Also, block size- jpg was limited to 8x8 chunks- j2k starts at 64x64.... so as you can imagine, a large bit of data can be compressed into a very small amount if you are sampling at 64x.
I can not WAIT till this codec is accepted by the industry- there is so much potention it's killed me not to have it available sooner.
Now with most laws, he could get his parents to sign the contract releasing such problems, but, he obviously violated the TOS. The government has said that anyone under 18 can't make decisions for themselves, and must have parental consent. Get that consent, problem solved.
Don't go ragging on Apple for this - if they weren't taking these steps, I'm sure a case could be made for child labour law violations.
MIT labs pointed out the miscalculation that there were MORE NEA objects than being reported.
IT's on their lab page, which was included in my submission of the story. Basically, they've come to realize there is a hell of alot more junk floating around than they've thought about.
Go figure- we haven't learned yet.

In the world of detectors an order of magnitude is about the only thing worth talking about.
Going from 5% efficiency to anything better than 10% would be an incredible leap. The filters they talk about are 'cutting' filters - you create them by depositing thin films of MgF or other salts on the surface of a piece of optical glass- multiple coats builds up a pass region while allowing destructive interferance to cancle out what you don't want.
The advantage is these can be turned sideways 45 degrees to 'reflect' the unwanted light to another detector (or in the case of IR, into a heat sink to dump it), but it also distorts the signal. Better to reflect it straight back.
This also has the advantage of going to fiber as well- encode a UV signal into a fiber optic (assuming your refraction index is high enough) and you can double or triple bandwidth.
It truly is a very important work - now if they can get it to work at 'space' temperatures and hard vaccuum;P
How the hell could I be redundant if I was the first person to say it?:P
I stick to my original story - it was unsafe and certainly pointless to post on slashdot about. Hell, I have friends that DO design roller coasters and they cringed when I told them that story.
I talked to a friend that was over there during the gulf war about the DU slugs that were being used. Unclassified speed of 1 mile per second (hint: Classified is faster:P) and able to penetrate a sand dune as if it wasn't there.
Apparently the enemy enjoyed the ostritch approach- hide the tanks behind a dune. A DU slug fired would penetrate the dune like a hot knife thru butter. If you punch in 1600meters/sec into a mass/energy equation, you can see a loosely packed sand dune is not going to offer sufficient resistance to even slow these things down.
Now when these things are fired they rest in a plastic, two piece mount. It comes apart (the mount) immediately after exiting the barrel. The mount is fatal to troops on either side (if the round leaves at 1mile/sec+, that mount is flying off at a 90 degree angle at pretty much the same speed - the nose is cone shaped so the air deflects it away from the round
This plastic piece could concievably abrade the DU slug (it IS hard plastic to withstand the acceleration).
This dust is then airborne, and could be breathed by practically anyone. Hence the problems and the health risks.
It wasn't as if anyone was LICKING the rounds:P
Where the hell did you get that idea?

Look, laws are written so that if you put something under your shirt and even move towards the door, you are guilty of shoplifting. Period.
I've watched a security guard run out the door, throw her badge at one kid, deck the other kid, and cuff them for grabbing some shoes and running. They weren't the only ones surprised.
What you are repeating is simply a myth. Do you HONESTLY think that merchants would simply ignore a problem once someone 'makes it off the curb' ?
Not only are you not a lawyer, you don't even bother to watch TLC or any other show that has even FEATURED stuff on shoplifting or other petty crimes.
Wow. If ignorance is not only bliss, you must be *insert high object here*
Reboot the computer, go into the bios, see if you can 'reserve' IRQs. if you can, mark them ISA - that'll stop them from getting assigned to windows or OS. Then just reboot.... disabling the PNP features forces them to be reserved. As long as the OS can still talk to it, it'll be just fine.
... create random noise to be used in a 'one time key' / 'one pad key'. Totally unbreakable. Especially if the message is short.
I remember the post you are referencing. There are cameras that photograph a number of lava lamps. Thru a couple of data munging operations, out pops a length of completely random data.
This was posted on some crypto/compression list awhile back about compressing totally random data. The guy was able to do so by underspecification of the problem. It was slashdotted, I believe.
Anyways, the same thing can be applied to picking up atmospheric noise/wind. Anything that cant be predicted or known at any other location should work for random data, thus you could use to encrypt. It is a "One Time Key" - no way to recreate the data without the data.
Awhile back there was a bit of research into high speed projectiles for busting up concrete. The soft plastic projectile was accelerated by helium piston (about 3 meters tall) downward. When striking it was able to cleanly break a piece of concrete in excess of 1foot thick.
The technology of getting ultra high speed projectiles over short distance isn't anything new- have you ever seen what a 3 mile/sec plastic ring can do to a block of aluminum (sorry, this photo sticks in my head) - it peeled it back like the shots of Doc Edington did in Stopping Time - a 1foot x 1foot x 1foot block was about 80% empty after the impact.
So getting the speeds aren't that terribly difficult and firing the 'bullets' only would need gas and a way of powering the ultrasonic pressure waves....
We just aren't used to having items travel that fast;P Just remember- it's over a very short distance, so air resistance doesn't start to build up.
If you don't understand the difference between colour space and format of the data, you really don't need to post a response to either this or the previously mentioned topic. Because you don't understand it, may I reccommend a book, Digital Encoding Solutions, available from Amazon for around $45.
In the professional arena, greys are reproduced slightly cold- more blue than Red and green. That isn't reflected in the Macbeth colour checker, but when you look at a neutral image, you'll pick the bluer one unless you know to pick something that looks more yellow.
