Ooops, I didn't mean to imply that MEMS/stirling engines would eliminate the gradient problem, it was something of a after-thought that they would be more efficient than the Seebeck junction.

The cable isn't likely to be the limiting feature here. The method of energy conversion doesn't just require heat, it requires a temperature gradient across the device. Here they're putting the tip in the fire to heat it, a

<pedant> Strictly speaking it's not the Peltier effect, but the Seebeck effect. One is the inverse of the other; Peltier junctions produce a temperature gradient when current is passed through, and Seebeck ones generate

Friction pads would probably have much more predictable wear (potentially in excess of the expected lifespan of the critter), whereas the discrete, stress-concentrating nature of gears would put them at higher risk of a single weak spot lea

I came across a paper on the first GPU keylogger[1] recently, which is quite clever, but maybe not sneaky enough. Sneaky-wise, hypervisor/system management processor/other embedded stuff (SMBus, BIOS/EFI, etc) are persistent,

My microcode experience is some years ago, and nothing nearly as complicated as modern Intel stuff, but depending on just what you can control, you might be able to induce excessive thermal gradients by working some bits flat out and disabl

If you have some crappy early-generation CFLs that have been used a lot, they can take 10-15 mins to come up to maximum intensity (although that max is still pretty puny, output wise).

I imagine there could be a similar reputation market along the lines of the write-my-college-paper services, in which you sell the bug to someone who can then take credit for it. Certainly I'm sure you could find some people who'd

I wonder if it would be practical couple the CPU directly to an externally accessible thermal pad, and have some sort of docking station which includes additional cooling. There are probably better cooling options available (liquid, heatpip

it's quite a common pattern in commandline apps to check if the stdout is a tty or not, and do things differently if so. So when you pipe it through `cat', it does the no-fancy-included output, much like the colouring that `ls&#x2

Depends how badly they want it. Use a 0-day remote exploit to get a login, exfiltrate data. Use a known, unpatched exploit to do same. Use 0-day/known local exploit with sophisticated spear-phish trojan to do same. Use leverage over do

The problem with "assume the maximum worst everything" case is that it places constraints on you that are essentially certain to be overly broad. Building a workable threat model & defending against it isn't practical (or

The better solution would (IMO) to have been to out-Top-Gear Top-Gear in some fashion, and use that exposure to also cover your point of contention. I think a suitable segment to parody would be the (rocket assisted) Mini Cooper Ski-Jump[1]

The obvious solution is more technology! Neural Implants with TPM/DRM. Maybe we have it already, but your hippocampus doesn't think you have Need To Know. I know it's been written about, but I can't remember where.
