Comment Only 2 DIMM? (Score 1) 133

And only supports 16 GB. Yes, thats too little, I usually run multiple VMs and 16 GB is the bare minimum.
That's why I have to put up with the Lenovo W540/W541, with his horrible touchpad, but hey, it got 32 GB and supports two HDDs plus an M2 SSD.
Even Lenovo W550 go back to only 2 DIMMs, but at least it supports 16 GB DIMMS, even if they are like 500 u$s each right now.

Comment Bitcoin? Nonsense (Score 5, Insightful) 294

Hi from Buenos Aires.

No, the solution is not going cashless. We don't have a banking problem. We have a currency problem, because the government steals from us in the form of inflation. Going cashless is giving the government more power to screw us.

Also we know very well how to play this game. If you can save, you buy other currencies like dollars. Or houses, if you are rich.
If you need the money, you convert and spend as fast as possible. Inefficient and somewhat expensive, but possible.

Bitcoin is easier to transfer, but too volatile. You might as well save in pesos.

Comment Bremsstrahlung effect? (Score 2, Interesting) 70

Xrays produced by the Bremsstrahlung effect are proportional to the voltage of free-electrons hitting an atom. That is, a 30kV electron would produce X-ray light with a spectrum centered in 30kV.

Rays have millions of volts and should be expected to produce X-rays of mega-electronvolts energy, this is gamma-ray energy levels.

But Bremsstrahlung needs vacuum, so I probably don't know what I'm talking about.

Comment Opera Developer (Score 0) 181

Firefox is dog slow in Ubuntu box (Core I5!) always taking 20%-30% cpu.
Chrome, not much better. Just tried Opera Developer (chromium based I believe) and the difference is abysmal. 0% cpu at idle, fast as lightning, I installed lots of plugins into Opera and it still it consumes no CPU. Why Firefox or chrome can't be like this?

Comment Re:Link to the NIF Status Update (Score 2) 429

From your link:

>The shot resulted in the highest DT neutron yield obtained to date, estimated at nearly 3 × 1015 (three quadrillion), or almost 8,000 joules of fusion energy

And then:

>All 192 NIF beams delivered 1.7 megajoules (MJ) to the hohlraum

That doesn't look like break even...
