Mach as a server... Can it be something else other than sluggish? It maybe OK as part of a computing cluster, because you don't make too many system calls, but I heard that Virginia Tech ran Linux on many of their XServes.
I have been wondering from the beginning, if they could insert an third party wireless card into my computer, why don't they insert a OS X boot DVD and enable root on my computer? Or simply grab my computer, they can gain TOTAL control of my computer much faster.
Right, there are too many troubles around fabrication of MRAM, mostly in the deposition and etching of multiple magnetic metal layers. But at least it is selling commercially, so it is practical now.
SVG development has been focused on code cleaning and bug fix for some time. You may see some speed and stability improvement in 2.0. And much more speed improvement in 3.0.
A ferromagnetic domain can be as small as 20nm in diameter or even smaller and stable at room temperature. A reference can be found at http://www.biophysics.uwa.edu.au/STAWA/magbac_5.ht ml. This size is way smaller than current fabrication limit.
Also, only two magnets are required to form a magnetic tunneling junction in the MRAM. While pretty complicated circuit is need to store one bit in DRAM.
I am a materials guy. So I know the story inside the plastic package.
The news is after all those years and money, MRAM is commercially available. Actually I thought IBM should have made it happen firstly.
It's not a easy job. Do you know how many years people waited for the commercial SOI wafer? Fabrication is not what you want, and what you designed to work, it is what you can get.
MRAM use the "spin" of electrons to read. So no need to worry about your head.
Don't know detail of the chips here. But I believe now it is available at large scale. Also, Freescale has made some progress in their MRAM technology, like use magnesium oxide replace aluminium oxide after they left Motorola. So it is very possible that the chips are different.
I believe the MRAM can reach the density of DRAM or even better very soon. Some Japanese companies are working on some interesting technology in this area. So, replacing HD with MRAM is possible at least in the portable electronics area like iPod in foreseeable future.
If I have non-volatile RAM faster than DRAM, should I think something different. A computer without DRAM and HD at all?
As FRAM, don't think it can compare the speed of MRAM. Due to the speed of ferroelectric phase transition, I think ghz is the ultimate limit of FRAM. But MRAM working Ghz has been shown. Anyway, I don't understand why you are talking about FRAM.
Making a 500GB FRAM component is... You know what I'am going to say.
The major advantage of MRAM is speed. They are extreme high speed nonvolatile RAM, even faster than DRAM. So if you need such a thing, you need to pay for it. Also, the current structure of MRAM is pretty complicated. It is made of multilayers of different metals. Depositing different metals onto silicon wafer is still something nasty though people have been depositing Aluminium and Copper for some time. There are some groups working on magnetic semiconductors, so they use common fabrication method to produce MRAM. So the price of MRAM can drop dramatically if these groups succeed. However, so far, the magnetic semiconductors are even expensive than the multilayer metals structure.
From what I am remembering, Freescale began small batch sampling of this kind of 4Mbit MRAM two years or 1 and half years ago, and now a available in large batch.
Agree with you, you can never stop Kevin Mitnick by switching to Mac. But at least we can enjoy a malware free time for 1 or 2 years by switching to Mac. That's enough IMHO. Then we can switch to Linux if desktop linux is good enough.
BTW, offtopic, is Kevin Mitnick driving a Lexus with a "HACKER" tag? I saw one recently, and a man with curly hair was driving it.

Student price is $69.00, and price from OIT of my university is... $10.00 per DVD, but no paper stuff.
The manual looks like the old one too. I read the manual when I was a teenager...

- 3 x NVIDIA GeForce 7300 GT 256MB [Add $300]
- ATI Radeon X1900 XT 512MB (2 x dual-link DVI) [Add $350]
- 4 x NVIDIA GeForce 7300 GT 256MB [Add $450]

So, how many clicks are needed now as it has bee improved greatly?
We should be able to play DHTML game in animate ascii art.
China and India just opened their border about 10 days ago, now India has learnt something from China, they are really quick.
A basic structure of MRAM can be found at http://www.research.ibm.com/resources/news/2000120 7_mramimages.shtml, no transistor is needed to read or write, no refresh need, :-) The space need to seperate two domains should be in the scale of Angstrom.

I can smell the old faithful Apache1.X smell, mm..., sweet. To be honest, I don't like your proposal too.

Chinese speak Chinese. This is a big problem.
is already there. And they can take a picture of the theft too.
Thank you, that's why we need the Firefox 2.0.
