Yeah, Intel's way ahead of the competition at this point. TSMC is just rolling out 40/45nm, and they say their process doesn't have any performance advantages over 65nm.
That's ridiculous. Obama has a record of compromise and working across the aisle.
McCain might have been centrist a few years ago, but he's pandered to the right for this election. Not to mention Palin, who is the most Bush-like candidate in this election.
My roommate got a MacBook recently, and he couldn't connect to our D-Link router. The fix was to put his MAC address directly into the router's DHCP config.
Actually, this isn't the first time this has happened. It's occured with Thinkpads and Linksys cards, and my D-Link card. Doing the MAC address thing and assigning static IPs solved a lot of problems with this router.
The reason, I think (IANAP), that this could be important to fusion reactions is that a photon loop within a plasma could heat the plasma to fusion-levels without the plasma trying to burn it's way through the outer walls of the reaction chamber. Current torus designs, I think (IANA nuclear scientist), run the plasma around the inside of a magnetic field, like cars on a racetrack, to get the energies necessary for fusion. This causes that super-hot plasma to push against the outer part of the magnetic field, which has to be extremely strong to contain it.
Not quite. In a tokamak, the plasma isn't accelerated around the torus to heat it. The basic method is ohmic, or resistive heating, where a current is induced in the plasma with magnetic fields. The current across the plasma resistance generates heat. This is kinda like your concept, but not exactly.
Ohmic heating is typically insufficient for reaching fusion energies. The other methods of heating rely on direct energy injection, either through RF or neutral ion beams.
Regarding containment, the magnetic field in a torus is not like a hard wall; it only presents a permeable barrier that particles are still able to diffuse across. If you turn up the magnetic field, you slow down the diffusion, but turn it up too high and you risk plasma instabilities. The key is to control the energy leakage to a point where enough energy stays in the plasma long enough to sustain the reaction.
I haven't read this new paper yet, so I can't comment on its applications to fusion.
Let's not forget about Bremsstrahlung. It's all well and good for a material to be strong, but high-Z materials in the first wall of a fusion reactor tend to get into the plasma and result in power leakage.
They got the graphics and atmosphere right, but I agree that the motivation behind the gameplay is murky. Why does the player have to kill Big Daddies and harvest/free Little Sisters? Oh, in order to unlock doors. Huh.
If the unthinkable happened McCain would already have a functioning administration, all the Cabinet positions would be staffed with (hopefully) competent folk, etc.
This is what scares me the most about another Republican presidency, even more than the prospect of McCain becoming president. A competent administration? I wouldn't hold my breath.
I had thought that NIM (Nuclear Instrumentation & Methods, owned by Elsevier) was the only game in town, but it's good to see that there's another journal for this sort of stuff.
(five minutes of browsing later) The Symmetry mag article has a link to the SLAC "blue book", which looks substantially more approachable.
Plus, given how slow my download is going, JINST is being slashdotted.;)
There are plenty of hurdles for p-B fusion as well, as the WP article points out. It sounds nice, but I don't think it will be possible any time soon, despite what the Polywell and Focus Fusion people say.

If you liked Knob Creek, try some Rye. The Wild Turkey Rye and the Rittenhouse 100 are good.
Does anyone outside of HEP use ROOT?
If you don't run as Administrator, none of that stuff shows up.
You sound like you're talking about ITER, not the LHC.
NIF is a bit of a special case, since it's used to simulate nuclear weapons.
That way, they can keep heat gradients along the whole ring well below 1K.
Damn, that's impressive.

AMD's 45nm is coming too, but I haven't heard much about it.
You forgot the links.

Just undoing mistaken moderation.

Yeah, I wonder why they haven't announced another JK-style FPS.

It's called ITER.
Lemmo add that at RHIC, we have a summer shutdown for the same reasons. It gets pretty warm on Long Island.
Nice work. I've wanted to get my hands on an e-ink display for some time, even if it's just a segment display, so I guess I'll check this out.
For now, I'm just leaving my Gmail open in Chrome. Gmail tends to junk up Firefox after awhile, anyway.

I like the ones in Emeryville, California.
Maybe they rolled that into Tegra.
