Re:Spintronics is already in use
With a quick google search, you can find a number of references to the use of spintronics for disk drive heads. Here are just a couple.
MAGNETOELECTRONICS, SPIN ELECTRONICS, AND SPINTRONICS are different names for the same thing: the use of electrons' spins (not just their electrical charge) in information circuits. One magnetoelectronic device is the magnetic hard drive based on the giant magnetoresistance (GMR) effect. In a GMR material, consisting of a stack of alternating layers of magnetic and nonmagnetic atoms, a small magnetic field can produce a large change in electrical resistance. Already a billion dollar business, GMR read heads will boost disk drive densities from 1 to 20 Gbits, and GMR might be incorporated into random access memory units as well (Gary Prinz, Science, 27 Nov 1998). The latest demonstration of spin versatility is the organized movement of a herd of spins over a lateral distance of 100 microns. In an experiment at UC Santa Barbara, David Awschalom first aligned the spins of a swarm of electrons and then nudged them across a semiconductor strip without the spin bunch falling apart. Such coherence will be necessary if spin currents are to transport information from place to place, particularly in quantum computers. (Nature, 14 Jan 1999.)
And this is from 2003, or at least, last updated in 2003:
A new approach to electronics, called 'spintronics' ( a short for spin electronics), is now emerging, and it is based on the up and down spin of the charge carrier rather than on electrons and holes as in traditional semiconductor electronics. Spintronics, also called magnetoelectronics including all the electronic devices where ferromagnetic thin films play an essential role, is today one of the most rapidly growing fields in electronics. A recent example of a rapid transition from discovery to commercialization in spintronics is the giant magnetoresistance effect (GMR), as applied to magnetic information storage. Although the first commercial product using GMR ( a magnetic field sensor) was available in 1994, the first products to have economic impact are read heads for magnetic hard disk drives, which were announced by IBM in 1997. The market for these products is estimated to be on the order of $1 billion per year and will increase the storage on a disk drive from 1 to 20 gigabits, merely by the incorporation of the new GMR materials.

Re:that is cool
I'm sure someone will manage to get it running some flavour of Linux. In the mean time, I'll be happy to run Contiki on my real C64 - unless someone can come up with a linux-distro for it that is.
If this 'new C64' turns out to be naught more than a reasonable standard PC bundled with an emulator and some repackaged software, porting Linux to it should be as hard as placing the Knoppix CD in the drive and booting it up...
Personaly, I would think it would be great if they brought back to life some of the old hardware - the VIC was an interesting grapichscontroller with it's independent sprites, and the SID could make music like no chip has before or after.
If you're a youngster and wish to learn more about one of the most influential micros in the early 80's, you may want to look at Marko Mäkelä 8-bit server. His document page is a treasure in it's own right.

Re:I just want a relational filesystem...
In regards to plain text/personal information -- have you thought about looking at Bayesian filtering for a solution to that? I haven't (yet) but the idea is festering in my brain.
Bayesian filtering is another of those words that mean a lot of things ;)
Nowadays it is usually used in reference to the techniques used for spam-filtering, which is a very specific task. Classification: Spam / Not Spam. Basically everything that uses the bayesian view on statistics can be considered a bayesian method, without considering the underlying model. In other words for many statistical models it is possible to derive bayesian optimization schemes (or "learning rules").
A widely used set of language models are the Hidden Markov Models. I'm planning to use them on an information extraction problem (populating database tables from free-text descriptions), and that's about the closest to the problem we're discussing that I've been. You could probably use them as a partial solution here as well, but I can't think of any really clever scheme at the moment.
For personal information one would like to have something that clusters the data into different categories. There are lots of methods for this. One I'm familiar with is Self Organizing Maps (an example paper about them).
And finally, sorry to be boring, but I'm not currently working on anything that would create something like the system we've discussed =)

Re:Will we ever have *real* AI?
Actually, synapses are the only thing in there. What we can't figure out is what they are computing. The brain is a massive parallel processor. the arguments in the field rest on the nature and instantiation of the computational processes and representations employed in cognition.
AI is trying to model the computational level of cognition, not the physical system. There have been many successful models of low level neural architecture, such as this .
Synapses really are the only thing going on in there, but those synapses are part of a body, which is a big, wet parallel processor -

Re:no good for large collections of documents
I hadn't heard of either technique
Sadly that is often the case. History is riddled with examples of mathematicians duplicating discoveries. That is my motivation for studying these types of techniques, a way to better compare scientific papers, to root out similarities. The history of the wavelet is a good example to discuss. The theory was almost hit upon several times, in slightly different fashions but the researchers involved never knew that others were making similar discoveries.As far as SOM stuff, Kohonen is the man.
There are indeed many things that can be done with SOMs, but to get really good, human-like, results is quite difficult. The problem expands when you need to consider different words for the same thing (e.g., cat/feline), and exclude words that appear identical, but aren't. Then the need to consider context becomes increasingly important (e.g., this article is not about cats). The complexity builds quite quickly.

Re:What if?...
But the fact is, as long as something is illegal, and there is money to be gained by enforcing the prohibition, America will find a way.
(Regarding 802.11b WiFi in coffee shops, there's many ways you might be tracked: if it's a paid-access arrangement, then they probably have your credit card. Or your Starbucks-Saver card, or whatever. Or the Feds can require that the MAC addresses of users be logged for some period- and begin to outlaw software which modifies the effective access. Steps like that would be a blow to free software as well)
The only really good strategy for keeping P2P transfers possible is to make them legal. Fighting to reduce the power of copyright is the way to start.

Re:Hardware prices in 1991...
Let's see...
CGA already did composite out, so believing VGA to composite could be done cheaply isn't very hard. In fact, with some tweaking of the card's clock rates (to something _less_) you can get pretty close to TV-Out without massively expensive electronics (even for then).
Next, how much is an external back-pack CD-ROM of now? About $200. A regular CD-ROM? $30. Difference in price? Over 6 times.
Dividing $1200 by 6 we get... $200. Now, I know that CD-ROMs were never that cheap then, but they certainly weren't all that overpriced!

Scary MusicThis is one of the games that came on the Knoppix live Linux CD. My young boys loved the thing, but refuse to play it with the music playing - it's too scary that way. I foolishly installed it on my Linux box, and they kept kicking me off to play their games.
I was pleasantly suprised to find there was a Windows port, so I could finally wrestle my Linux box back from them, although they keep insisting on playing Frozen Bubble, but mostly Rocks and Diamonds.
One of the great things about Rogue (read: NetHack) was that it gave *nix a unified way of talking with various and diverse terminals.

Ken Biba?
Given the qualifications and history of Ken Biba listed in the article
Biba started in security and networking R&D 30 years ago with Mitre Corp. and was a member of the Advanced Research Projects Agency Transmission Control Protocol (TCP) Working Group
I wonder if he is the same Ken Biba that worked on/devised Mandatory Access Control (MAC) and the Biba Integrity Model.
There is a good description of MAC here, and an explanation of the Biba Integrity Model here. -
VGA to TV conversion, DIYFor the electronics hackers among you, there's a rather simple circuit for VGA-TV conversion described here.
The principle is simple, because the TV is just a fixed frequency monitor that takes RGB and timing signals. The circuit only converts the timings. This means a little extra work on the software side, as you have to configure X for the TV's resolution and frequency. Unfortunately some video boards (such as mine) have a lower limit on the frequency and the circuit won't work well. Otherwise it might be worth the hack

Yes your honor, it's true, at a load level of 16 clients Windows 2000 filesystem throughput flat lines vs. Red Hat Linux with Samba which is still scaling up nicely with 28 clients.
Does Windows 2000 mask the true power of the Intel hardware? Examine the report and look at the benchmark graphs. Decide for yourself if it's FUD or FACT.

Consider also studying abroad(this one for the one who was not looking for only an online degree)
Depending on what is the field you would like to specialize in, think about studying abroad. For example, I have heard that studying in Finland in HUT or TUT for example might be a major boost both for your skills and employment opportunities especially if you plan to specialize in wireless stuff. (Why? Much of it originates from Nokia)

Re:The truth is obvious.
I thought the world was on the backs of four elephants then a turtle.
For those who are not familiar this is a Terry Pratchett thing.
Actually, it's an old myth that's existed in some shape or form in almost every culture. The closest one is the Hindu myth, where "we find the idea of a lotus flower growing out of Vishnu's navel. Swimming in a pool in the lotus flower is the world turtle, on whose back stand four elephants facing in the four compass directions. On their backs is balanced the flat, disc-shaped world." (The Turtle Moves)
It's this old belief that inspired Terry Pratchett to come up with Discworld, which is "a geological pizza (only without the anchovies) on the back of a starturtle, called Great A'Tuin (sex unknown). The disc itself sits on the back on 4 elephants who stand on Great A'Tuin's meteor pocked shell. Occasionally one of them has to cock its leg to allow the sun to pass." (Turtles All the Way Down) -

Everybody knows the answer is standards!Let's do it the standards way.
I want to do a nice little page, and do it in XHTML because it's The Way Of The Future (or I want to display a little math, which only XHTML+MathML allows without resorting to ugly inline images). The tag soup itself isn't a problem, I just close all my tags and make sure the doctype declaration says XHTML instead of HTML, as prescribed by the standard.
However, is this enough? The document is now XML, and therefore should have a <?xml declaration, if only to specify its encoding. Except that said XHTML standard says it is optional if the encoding is UTF-8 or UTF-16, or has been otherwise determined (think HTTP headers), which contradicts the XML standard, sec. 4.3.3, the last two paragraphs, one which says that no declaration and no other information means mandatory UTF-8, and the next one "It is also a fatal error if an XML entity contains no encoding declaration and its content is not legal UTF-8 or UTF-16."
So I need a declaration no matter what. But according to this page about the different layout modes in current browsers, MSIE will react to an XML declaration by switching to "quirks" mode, which is precisely what I wants to avoid by sticking to the standards... And I wouldn't want to lock out 85% of WWW users, wouldn't I?
But wait, this is only if the page was served with a text/html content-type. The right answer would then be to use the standard content-type for XML/XHTML... which should be application/xhtml+xml! Yes, "application"! Now if I use that content-type, all browsers I have at my disposal except Mozilla (MSIE5, Konqueror, Links, Lynx...) either consider the page an application and offer to save it to disk, or display it as-is! Same with the second-best, text/xml.
Okay, am I the only one experiencing this? Any point in not using good-ol' HTML4 and avoid doing (yet another kind of) horrible bugware?

Re:BS Required
Sure they do, I bet every university out there has a course on practical computer security. Should be, at least. My university's is here, probably not very interesting though since it's in Finnish.

Then you make a written plan then you do the hack (within the lab network

I don't need no stinkin' Wizards!!!!
Do you think it will spell an end to D&D ?
You mean, will somebody go out and burn all the DM guides and monster manuals? Doesn't seem likely.Oh, you mean will D&D software survive. That has nothing to do WotC. They only control things that are called D&D. Example:
A long time ago a undergrad name Michael Toy used the D&D fighting system and monster stats to create a Curses game called Rogue, the predecessor to NetHack. (Ignore Glenn Wichmann -- he's a legend in his own mind.) TSR didn't care for this, of course, and sicced their lawyers on him. The only result was that all the names got changed to non-D&D things. Which was actually an improvement -- there's no place in the D&D universe for my own favorite player character, the Tourist
Bottom line -- you don't need the media monopolies to play games, any more than you need them to make music. Pity about Farscape though.
