High power electronics system usually has some acoustic side effect commonly known as "coil whine" caused by mechanical vibrations in coils and capacitors amplified by the PCB. In the design of Airtop motherboard special attention was given to make it inaudible. The power supply is also silent.
Go to the stadium in shorts and t-shirt, freshly washed (and dried indoors).
Bad Idea:
[...] All the operator has to do is pinpoint a spot on the court or field using the screen, and the Audioscope works out how far that spot is from each of the mics, corrects for delay and then synchronizes the audio from all 315 of them. The result is a microphone that can pick out the pop of a bubblegum bubble in the middle of a basketball game..."
That's not quite right. 3DES is not weaker than it has to be. Meet in the middle attacks are possible for all triple encryption constructs.
The second operation is an decryption so that if both triple des keys are the same it is compatible with single des. It does in no way weaken the algorithm.
For any triple encryption the complexity of attacks is only squared the base complexity not cubed as you would expect because of meet in the middle attacks. That's also why normally only 2 independent keys are used and not three. You do not want to suggest a higher complexity than you actually have.

I know your problem, I've had a Lenovo X230t.
I now bought an Alienware 13. It has almost everything you want, except a removable battery.

Every prime number has a prime number of digits in some base.
Can you prove that?
