You can boot to Linux, then run Gimp. Although I don't see why you would.

I think you can get to Picasa, and do some photo editing.

I use my chromebook all the time, but not for photo editing.

Of course, Forbes has always been Microsoft friendly.

I lived in CA from 1979 to 1992.

The entire time I was there, and on until today, I have heard talk of splitting up the state.

Hi.

the Nyquist limit of the audio sampling hardware of a cell phone over instruction rate of a modern CPU is a pretty small fraction.

The "audio" in question is most likely all below 24 kHz, that being the Nyquist limit for the 48 kHz sampling hardware, unless it happens that some phones can actually sample faster, and have microphones that can respond to higher frequencies.

The instruction rate of the CPUs in question is many times that frequency.

It doesn't sound likely.

Using multiple cores turns out to help the attack (by shifting down the signal frequencies).

Say what? Through what mechanism would multiple cores shift down the frequency? And what about parallel instruction streams contributing to noise?

TEMPEST was a details-secret government requirement meant to defeat means of eavesdropping on classified computer data from its electromagnetic emissions. I guess they need to include audio too.

My impression is that the noise comes from the power supply, not the CPU. I can certainly hear it with some computers, and it is related to work on the video card in my experience. I'm astonished that you can actually pull data from that, and in fact I'd like to see independent confirmation before I believe it.

Curiously, in my youth in the 60's, we referred to Luna-9 as a "hard landing", and the first "soft landing" was Surveyor 1 three months later. Now, it's clear that the Luna 9 lander really was a soft landing (similar to the landings of the Mars Pathfinder and Spirit/Opportunity rovers) and we were just ragging on the Soviets.
