Comment lithography applications (Score 1) 61

So this would presumably be used for extreme ultraviolet lithography?

I guess this paragraph from the Wikipedia article may be relevant:

A further characteristic of the plasma-based EUV sources under development is that they are not even partially coherent, unlike the KrF and ArF excimer lasers used for current optical lithography. Further power reduction (energy loss) is expected in converting incoherent sources (emitting in all possible directions at many independent wavelengths) to partially coherent (emitting in a limited range of directions within a narrow band of wavelengths) sources by filtering (unwanted wavelengths and directions). On the other hand, coherent light poses a risk of monochromatic reflection interference and mismatch of multilayer reflectance bandwidth.

No, you're not the only one. I think the PA support is particularly good in Karmic. I upgraded recently and it fixed the last remaining issue I was having. And as a longtime SPDIF user I love the hardware profiles that let me easily select digital vs analog inputs and outputs.

Did you RTFA? The data they supposedly have is for an implosion device, that would be suitable to go on a missile. So I don't think the conventional wisdom of "oh, uranium is easy, it's just the extraction that is hard" really applies here. Any they would be able to apply this knowledge to building weapons that use plutonium, which will be the next step once the Arak reactor comes online.

If you want a thin and light notebook with a decent-sized screen that doesn't cost an arm and a leg, a 12" netbook is perfect. The price jumps straight from around $500 to around $1500 for higher-powered subnotebooks in the same form factor. Aside from the terrible GPU, I like the Mini 12. I'm not saying I buy the argument that Intel forced this on Dell. I think it's more likely Dell is ready to come out with a better alternative in the very near future. It's just marketing: they probably don't want to distract from a new product launch by canceling a product at the same time.

Comment and the figures are wrong too (Score 1) 403

If in 2050 each person needs 109 hectares of arable land, we are going to be in trouble no matter what. With the population at that time estimated to be 9 billion, and given that there are about 3 billion hectares of arable land on the planet, we might need to come up with a few hundred thousand more earths.
