Comment Re:Distillation? (Score 1) 320

Sure, that's absolutely correct, the distillation would work. It would, however, take much more energy. Instead of boiling off ~20% (by volume) of ethanol which boils at 78C, you'll need to boil off 80% of the water which boils at 100C. And then boil off the isobutanol (to separate it from the yeast and other crud). Most yeasts will conk out well before 20% ethanol, they basically die in their own excrement. I doubt that this fermentation to isobutanol would go to 20%, probably less.

Comment monatomic Hydrogen? (Score 1) 269

I'm quite surprised that the hydrogen atoms didn't condense in to molecular Hydrogen (H2). Monatomic Hydrogen is remarkably unstable at any temperature above 1K. If they isolated 38 atoms for 1/6 of a second, that seems like plenty of time for chemical reactions to take over (i.e. formation of H2).

From the article at Nature:

To trap just 38 atoms, the group had to run the experiment 335 times.

I'm guessing that the 38 atoms that they isolated were during different runs of the experiment.

Comment Re:Linux already runs on thousands of cores (Score 1) 462

I beg to differ. I have access to the following system:

$ grep -c processor /proc/cpuinfo
127
$ uname -a
Linux xxxxx 2.6.16.54-0.2.12-default #1 SMP Fri Oct 24 02:16:38 UTC 2008 ia64 ia64 ia64 GNU/Linux

...that's a single instance with 127 processors and 256GB of ram. It rocks. If you have the means, I highly recommend picking one up.

Comment Out of Stock (Score 1) 475

I find it interesting that Zen Magnets are currently out of stock. I'm sure that it's easier to keep production quality high when dealing with smaller production runs, so maybe BuckyBalls' QC is slipping as they try to keep up with their larger market share?

Comment Re:First rule of forming an A-Team of IT... (Score 1) 246

From alt.sysadmin.recovery FAQ v1.799999999999999998... (1 April 1974):

4.4) Revolvers, cyanide and high voltages: The pros and cons of various luser education strategies.

There has been a great deal of debate on ASR about the best way of dealing with lusers, and at this time no consensus has been reached. What we can suggest, however, is to be sure it is painful, clean, and doesn't harm the computer. That unfortunately leaves a lot of options out; you can't just throw a grenade at them; it will hurt the machine.

Comment Re:Not so small ... (Score 1) 118

Not small, but also not uncommon. According to NASA JPL:

Although neither of these object has a chance of hitting Earth, a ten meter-sized near-Earth asteroid from the undiscovered population of about 50 million would be expected to pass almost daily within a lunar distance, and one might strike Earth's atmosphere about every ten years on average.

...so this happens pretty much every day. This time, however, we know about it.
