Please refer to me as Holography Nazi for the remainder of this post:
The external hologram surface may turn out to be sensitive to damage (though I can hope for the use of confocal optics, etc. to image the volume despite surface imperfections or contamination) and the volume may be vulnerable to sunlight.
The external hologram surface may indeed be sensitive to damage. This is why Harddrives come packaged inside of metal cases. Sunlight would be blocked out as well. Additionally, magnetism, which damages non-optical drives, would not harm this drive. Generally speaking, optical storage devices have always been more reliable then magnetic media.
The hologram technology used here showed promise because it can be multiplexed with different laser colors and at different angles, but the 'clarity' of the signal goes down with the square of the number of channels, until it is unintelligible. This does not bode well for rapid breakthroughs (though if we could predict them, they wouldn't be breakthroughs). Precise alignment is necessary to assure high density, reliable readings. it seems likely that the 2003 holographic drive will be larger, more expensive, and offer no appreciable advantage (aside from ?magnetic insensitivity?, if that counts)
You didn't learn much about holograms when you made one in 1977, because much of what you said here is wrong. As an explorer, you probably made a reflecting-light hologram, similar to what is on a VISA card. These are inaccurate as the picture changes depending upon the angle and colors of light reflecting upon the foil. Using a transmission-light hologram is much more accurate. When a monochromatic light source (expanded laser) shines upon the film, the original image is created in 3 dimensions. The image is very insensitive to precise alignment of the lasers. The laser can be angled within a range of more then 10 degrees. The film can hold more information then one 3-D image. This is what IBM is refering to. Additional monochromatic light sources can store multiple images in the film, each constructing a 3D image when transmitted through the film. After too many images are added to the film, it can't reconstruct images as well. Think of this as overexposing regular film, it's almost similar to this. The solution to this is not to have many images. One true 3D image (which holograms construct - not false ones like 3D glasses construct) already holds much more information then it's 2D counterpart.
Aside from the probability of actually seeing a production drive someday, I think that several other holographic technologies are more promising. and none of the holographic technologies show signs of exceeding the practical capacities of straight optical media in the predictable future -- i.e. the next three years. Standards, not technical capabilities, block DVD-R from coming out *this year*
I'm a little unsure about the practicality of a holographic drive in the near future, but IBM is known for applying it's research to products. The copper technology and advanced layering of ceramic insulaters/semiconductors are examples of this. Holography has already met and surpassed traditional optical methods when it comes to nondestructive testing.
I recommend Optical Methods of Engineering Analysis by Gary Cloud for more reading in the area of holograms and how/why they work. This book is very applied and mentions many practical examples of holograms in industry.
Finally, my grammar nazi side is pointing out that you misspelled manufacturing. It's late and I probably misspelled more then just that, so I forgive you.
The word steganography literally means covered writing as derived from Greek. It includes a vast array of methods of secret communications that conceal the very existence of the message. Among these methods are invisible inks, microdots, character arrangement (other than the cryptographic methods of permutation and substitution), digital signatures, covert channels and spread-spectrum communications.
"
Steganography is the art and science of communicating in a way which hides the existence of the communication. In contrast to cryptography, where the enemy is allowed to detect, intercept and modify messages without being able to violate certain security premises guaranteed by a cryptosystem, the goal of steganography is to hide messages inside other harmless messages in a way that does not allow any enemy to even detect that there is a second secret message present" [Markus Kuhn 1995-07-03].
The grammar nazi is happy to have assisted (and plagiarized).
The grammar nazi supports genetic tampering. We can finally build a race of Uberhumans!
We can start by fixing ^chuck^'s grammar gene. For a start, he needs to capitalize Redmond. Although he seems to have a strong vocabulary (prehensile was excellent), he is unaware that plain steel is much stronger then titanium (generally speaking). Perhaps the physics is outside of the grammar nazi's realm, but I'm a little worried about super sonic hearing. How can one hear sound faster then sound? I don't think that this would allow Linus to hear into the future. Increasing Linus's clairvoyance gene would be a better idea.

It sounds like you, aTRaTiCa, should offer one of those cleaning kits to the submitter of this story. Here's another issue/problem to resolve. I was at the house of a friend who is a big-time smoker. His computer used to be the same off-white beige of most every computer, but now it is a nice bright shade of nicotine. I tried wiping off this nasty nicotine and sure enough it comes off onto anything that you wipe the case with, but it also still remains on the case.
1. Is there any way to actually remove this foul nicotine? 2. Doesn't the fact that it comes off onto a rag and simultaneously stays on the case defy the laws of physics? Could we invent any anti-matter or cold fusion devices because of this property?
Interesting train of thought MagnusDredd, You stretched it out a great deal, but this is certainly possible.
It's probably a typo, but I just wanted to point out your misspelling of the word software towards the end of your comment. Please try and be more careful in the future.
Actually, I read about it in the beginning of the Oreilly book titled, "Samba". I forgot the actual pattern match, but I remember trying it and it worked (Solaris). I just checked and samba isn't in my/usr/dict/words either, but it is in the Solaris/usr/dict/words on my school network.
I agree with you David, but I will admit that Conor is right, too. I edit it on multiple computers. My advisor always wants to see the new changes to my thesis. CVS allows me to see what I changed since the last release and only give him the new stuff.
Although I haven't used it yet, I like the idea of going back to a previous version.
On a different note, I went to a Engineering Analysis workshop sponsored by HP, and I got the following idea: If you could design an easy to use Web interface for CVS (this alone wouldn't be too hard), then you could sell it to Engineering Dept. Managers and make millions. All the managers at this workshop a) didn't know anything about computers, b) have complicated multi-file engineering projects that their employees are working on (CAD files, Analysis files), and c) are willing to spend big $$$$$ on 'file management solutions'. The powers of CVS and a friendly interface would do the trick.
I keep my thesis in a big CVS repository. It's in LaTeX so it consists of many different files. Has anyone else tried any -non-programming- things in CVS
I'm impressed with Intel's quick and somewhat knowledgeable response:

The CRT version gives a much better resolution and viewing experience than a passive LCD display would. Further, with smaller display, the Internet is often clipped, or reformatted, so that the Internet looks different. We made a trade-off--- good display, full Internet for aesthetics.
Does anyone know if Metallica followed through with any of the lawsuits? I was banned because of a KMFDM remix of a Metallica song, but I just started using Gnutella instead. My IP address was banned (static) instead of my username; I tried to log in with a few different names, and then downloaded Gnutella.
I think that Courtney Love brought up many excellent points that I haven't heard until now. Since I also like her music, I'd love to go pay to download songs from her site right now, if I could.
Check out the GARAGe at Michigan State University. They use Genetic algorithms for many different and interesting problems. From consumer preference predicting to financial analysis.
There code is called Gallops, and it seems very scalable. There is a Meta-GA built into Gallops that allows the GA to genetically change itself in order to be the most efficient GA.
This is cool stuff!

Who knows though? Maybe they can strip the hell out of some portions of gnome and make it fast and light. But at the same time, if they do that, will it still be GNOME?
Basically, they can (and did) strip Enlightenment out of gnome and that's a huge performance increase.
I think that your new internet appliance is quite ugly. Before you delete this comment as a random flame, please consider that a flat lcd screen would have given your product a slim, sexy look, similar to Netpliance's I-Opener. I know that smallish lcd screens can be quite cheap. Please consider using one in the future.
Finally, what made you choose to use a keyboard instead of a touch screen? That gives the whole package a computerish look which is what you state that you are trying to do away with.

I tried exactly that; it didn't work.

Yeah, that would suck. They'd have a monopoly on computing.

No, they'd never do a thing like that. You're talking madness!
