Just because you have two systems which conform to IEEE 754 doesn't guarantee you'll get the same answer for every floating point operation. You're easily able to produce different answers depending on the width of the registers in the FPU. Take a single-precision device which has a 64-bit internal floating point register vs one with a 32-bit one, both conform to 754, however due to rounding the one with a 32-bit register can provide a subtly different answer. The book Accuracy and Stability in Numerical Algorithms is pretty good on this.
Neil Stephenson talked about this in snow crash. At last, we have sintered Armogel. All I need now is a sword!

I read the chronoliths, and I must say.. it was perhaps the worst book I've ever read. Not just due to the fact that the plot lept about like an inebreated baboon, nor that the ending was "just plain crappy"(tm) but the fact it was disappointing. The concept was clever and held such promise, and the author did absolutely nothing with it. I only ended up with the feeling that he rushed to get this out in order to plant his flag as the first book to use this concept.
If The Chronoliths was an example of Robert Charles Wilson's usual fare (and God forbid this was above average) I can only implore people to save an evening of their lives.
It's a harsh reality, but with the patents palm aquired with buying handspring, they may just sit on them to ensure no competitors get to use them.
It's happened before, remember SyQuest? They made removable storage similar to the zip and Jaz drives, only theirs were virtually indestructable, and based on tried and tested winchester technology.
When SyQuest finally went titsup.com, its only competitor iOmega bought the patents, and they havn't seen the light of day since.
I'd hate to see another technically superior product get betamaxed by a large company.
For years we've been bombarded with commercials advertising "deep pore cleansing" to help reduce clogged pores, and make us leap tall buildings in a single bound.
But now by shoving food down our pores, we will be suffer unslghtly blackeads, bet GI-Jane wouldn't go in for this.
I just use an aluminium flight case (you know, the aluminium box things, metal catches, and foam inserts). They are about £30 from most good camera retail shops, as they are generally use them for carrying camera lenses, but they work just as well for LCDs.
For several years the russians have been selling "synthetic" diamonds. These are grown at extremely high temperature and pressure from either the seed of a real diamond or a piece of graphite. The results are often flawed, but good enough to be sold to the drilling markets. However, large flawless ones are available (at a price), the only way to tell them from a real (as in dug out of the ground) one is the synthetic fluoresces for a microsecond or so longer than it's natural counterpart.
This has understandably got DeBeers rather worried.:)

But if you want to ensure that your diamond has a pristine past, it's the only way to go.
If I recall correctly one of the effects of spending so much time in microgravity is that calcium is not deposited correctly, hence astronauts exhibiting low bone mass after long spells in space. However this also works with teeth. 700+ days would result in every one of them falling out.
How's that going to look in the pictures? Mankind sets foot on a new planet, and 6 gummy grins stare back.
Same idea, different band, I got the new Counting Crows album off gnucleus http://www.gnuucleus.com However I still bought the album, and still go to the concerts. I think if someone is a big enough fan, they will want the shiny thing, not just the music.
Are people going to eschew going to concerts when gargoyles go to them, and people can enjoy pogoing for their lives via VR?
Baby, probably the first programmable computer, designed and built at the university of manchester and first run on June 21st 1948. Has been recently rebuilt for it's 50th anniversary.
In Northern Ireland, we have plastic five pound notes, they are durable wipe-clean, and generally can take a lot more abuse than their paper counterparts. Details available from: www.polymernotes.org/new_page_13.htm
Though they don't mention the fact that our sorting machine still havn't been reprogrammed to accept them, nor the fact that though they survive being washed in your trousers they have a habit of melting into them when subsequently ironed.:)
As I understand it, many courts are unwilling to admit evidence that isn't stored on write-once media. As such, many architects etc.. still use celluloid to "cover their asses" while for day-to-day use make invest in digital cameras.
Flash-compatible proms sound like an ideal way to save lugging round two separate cameras.
Hasn't something similar been done with the Quagga?
I seem to recall that they were able to extract DNA from an improperly stuffed Quagga carcass. (The last one dying in a dutch zoo in 1833).
There is a selective breeding and research program currently underway http://www.tecsoc.org/pubs/history/2001/jun4.htm to breed them back into existance.

I was once told that during WW II:
When the Germans fired, the British ducked,
when the British fired, the Germans ducked, and when the Americans fired, everyone ducked.
I guess some things don't change that much.

May I point out the word is virus, the plural is viruses. There are not such thing as viri; and the people who say virii are doubley wrong!
This is perhaps the same group of people who say CD's an CPU's. It's a bloody plural! There is no apostrophe!
Can we please god kill people for basic grammatical mutilations?

When can they grow up lumps of me? Cannibalism is kinda frowned upon these days, but this could be the next big thing!

Personally, I bought an ATX case, and separate drive case from Sight Systems, cost under 500ukp, and you can even choose the colour!
Personally, I went for the rather nifty black ones, though if you are so inclined pantone-414C is still available. That's beige to you and me.
The quality was excellent, far in advance of standard pc cases including vibration dampening, and not a sharp edge anywhere to be seen!
The cabinet an (18u including acrylic door) made by proel and purchaced through a high-street music store was 220ukp (including VAT and delivery).
