In other news, government officials express concern that women having sex for free will make it "virtually impossible for us to enforce prostitution laws."
Greenspun's Tenth Rule of Programming:
"Any sufficiently complicated C or Fortran program contains an ad-hoc informally-specified bug-ridden slow implementation of half of Common Lisp."
An interesting technology. Long-term it looks like it has a lot of potential. But for the time being, it looks like MicroOptical (http://www.microopticalcorp.com/) is a better choice for wearables. They're less obtrusive and they can already do color. And, while they're still not cheap, they are cheaper.
I definitely want to see power-consumption and resolution specs for Nomad, though!
Anybody else bothered by the fact that the article kept describing this as a holographic display?
I just tried to go to the SE Linux page and it looks to be pretty well slashdotted. I wonder if we'll see any stories about DoS attacks on the NSA in the news because of this post...
What they seem to be implying is that they are increasing the depth of the field oxide, seperating the poly from the substrate. This would hardly take five years to come up with....
This misses the point. The field oxide only provides lateral isolation between tubs.
In a typical CMOS process, the devices are constructed in n-type and p-type tubs which are implanted into the substrate. The field oxide helps with the sidewall, but you still have parasitic capacitance and leakage currents at the bottom of the tub.
Silicon on Insulator tries to reduce the parasitic capacitance and eliminate some nasty problems with parasitic bipolar transistors formed by the implant regions. Originally it was done by growing a thin layer of crystalline (epitaxial) silicon on a sapphire wafer, but this is expensive and has problems caused by mismatch between the lattice spacings and by unequal thermal expansion.
The problem with an all-silicon SOI process is that the silicon dioxide that is used as an insulator is amorphous, so it is easy to grow polycrystalline silicon (poly) on it, but difficult to grow an epitaxial layer. The approach that IBM is using is called SIMOX, for Separation by IMplantation of OXygen. This works by implanting a high dose of oxygen ions into a silicon wafer and then annealing it, forming a well-defined buried oxide layer beneath the existing single-crystal silicon.
Another Founding Member (tm) of the ATL is a political lobby group called the Association for Competitive Technology (ACT). Care to guess who is also a member of *that* organization?
If you mean the Sonic Blaster, it had no speaker. It had a compressed air chamber that you pumped up using a lever on top of the gun. When you pulled the trigger, boom! In the original TV commercials, they would fill the barrel with smoke, and you could *see* the shock wave that came out of the thing... very cool!

#4. Profit!

Jeez, now even the courts are trying to tell us that real programmers don't need strong typing!

Great, another "Consciousness Physicist." I would suggest that you would be better off reading *anything* by William Calvin, or Daniel Dennett.

The Sonic Blaster rocked! I had one of these as
a kid. (In fact, I could just about have passed
for the kid in the picture.)
They don't make 'em like that anymore...
