> I cringe at the mere thought of encrypting my whole main drive, OS and all. Bleaaggghhh! But if you don't, you have to clear your logs once in a while.

Why exactly?

With Truecrypt, I have >>1GB/s possible throughput, so even saturated SATA-6 from an SSD will not be limited by CPU power - hell, 1 or 2 cores are not in use anyway, nearly all of the time.

And defect sectors or other snafus? Well, if a 4k block is dead, it does not matter if it was encrypted or not. Its not like the whole thing breaks down...

You are old fashioned.

A good e-reader only needs to be charged every month or two (thanks to Lithium batteries), and is using micro usb, so you do not need a charger, cause if you are gone from home for more than a couple of weeks, you might have your cell phone charger or a laptop or something with you, anyways.

Comment Re:The Pentium Pro did it (Score 1) 605

Don't forget the AMD Athlon.

Pentium Pro was good (at least as long as you stayed away from 16 bit code), but the Athlon showed that you can do stuff that only PA-RISC and Alpha had before with x86 ( in particular, superscalar FPU with parallel mul/add/memory op).

At that point, it was clear that you can shove EVERYTHING into x86. And who cares about 8 (now 16) registers, if you never touch them anyway and there are 200+ rename register under the hood?

Do not ignore one thing of the PS4:

It is the first time a x86 CPU has EVER been supplied with that much bandwith.

Yes, it is shared memory, but with low GPU load, the x86 CPU has >160GB/s bandwith available. Thats enough to provide a load and story for each core and clock cycle.

2- No, its NOT the same as CNG. Because the energy density of adiabatic expansion is a LOT less than the one of natural gas combustion. So a much higher loss fraction during the compression cycle AND combustion waste heat cannot be used to pre-heat the compressed gas to counter valve freezing and whatever.

A couple millon.

But with stars being point sources, with a telescope you can determine shifts of the center of brightness between stars very very accurately, especially with a sat telescope outside the atmosphere.

There ARE, of course limits, and the method becomes useless for stars many 1000 ly away (in the sense that the indirect methods, despite all their error possibilities, become more accurate), but 400ly is still doable.
