Gimp is an offensive term when used to refer to someone who is lame or handicapped. It may also evoke "the Gimp" from Pulp Fiction in some people's minds. However, it has other meanings, which are perfectly acceptable in polite conversation. Furthermore, it is a refreshingly straightforward, unforced, (indirectly) recursive acronym.

Personally, I am fine with the name and I picture the cute little whatever-it-is logo when I hear it, if I picture anything at all.

It's unlikely that a would-be assassin will learning the art of medical implant hacking in assassin school on the off chance that he'll one day have a target who just happens to have such an implant. As with today's black-hats, who focus on Windows over Linux (well, until the recent Mac headlines), their efforts will concentrate where they get the most leverage -- on cars. Even people who don't drive almost surely step into a car fairly regularly. The high-tech hacker-assassin may eschew the "old bomb under the chassis" bit, but why not a drive-by reprogramming of the ABS computer to disable the brakes when the car hits highway speed?

Great TED talk on this topic here

Can anybody make any sense of this passage from TFA?

Air is drawn in through vents in the nose of the turbine and a generator heats it producing steam. That steam is then fed through a cooling compressor to form moisture that gets condensed into water.

Produce steam by heating air? I thought you got steam buy heating water. And what the hell is a cooling compressor. Doesn't air heat as it is compressed?

OK, I got the sarcasm out of the way. But really, I'd like to know how this really works and the articles explanation strikes me a pretty garbled. What is accomplished by heating the air, only to cool it? Or is the air really heated as it is compressed, then gets cooled under compression (in the heat exchanger) so that when it goes though an expansion valve the cooling effect results in condensation of the humidity?

I'm sure this device works fine but the poor explanation by a "science journalist" leaves a lot to the imagination.

The yield must depend on moisture. Is this going to be useful in the Sahara or just outside of Las Vegas?

From TFA:

A prototype unit was constructed and erected in Abu Dhabi 6 months ago and has consistently produced up to 800 liters of water a day.

There's that "up to" again. This is marketing speak. I make a point of mentally translating it to "never, under any circumstances, more than", or "between 0 and". Anybody who intends to give helpful information gives an average and possibly standard deviation, including whatever conditions needed to attain those figures. If your only intent is to promote your tech, you say "up to".

On another note, this is not likely to be used to provide drinking water where seawater or ground water high in salts is available. You'd get more bang for your wind power with desalination. On the other hand it could be very useful for drip irrigation, where salts remaining in desalinated water and even relatively good ground water present long term problems for agriculture as they accumulate over time to concentrations that no crops can tollerate.

IANAL, but I do play Devil's Advocate on Slashdot from time to time. So forgive me, mods, if I criticise this criticism of ID. It should not be taken as a defense of the indefensible. But I just can let such sloppy logic go unchallenged.

Intelligent Design comes in two forms. The first is when we admit that it is just a euphemism for creationism. In this case, the theory of evolution (as well as most of the field of archaeology) clearly contradicts the story of Genesis, thus rendering the two incompatible.

There are many versions of creationism besides the Christian ones. You'll have to do better than that to prove incompatibility

This form of ID is basically the claim that evolutionary optimization can never escape local optima to discover global optima - something a competent applied mathematician knows to be false.

Wrong, wrong, wrong. The ID propenents are on very solid ground in their belief that something as complex as an eye, a flagellum or the blood clotting cascade could not evolve given that the partially formed proto-systems are useless. That is abolutely the case. The problem with ID is that this uselessness is not a given. It's not that a random process can result in an escape from a local optimum (which is true to a limited extent, but not really relevant here). It's that a partial eye is not useless. Nor a partial flagellum.

Not sure parent deserves a +5. Monsanto does not, in fact, sell pesticide resistant corn seeds. And if it did, the corn would be herbicide resistant, not insecticide resistant. Plants, including corn, are already insecticide resistant -- they're insecticides, after all.

Monstanto is working on pest resistant corn -- specifically, corn resistant to corn root worm. So, if the bees were actually eating the corn or the corn pollen, that might be something to look at.

The summary accurately says the "same base area", i.e. footprint. This is not the panel area. The GP is underwhelmed with this announcement for good reason. This is not a breakthrough in efficiency in anything except the area required to erect the structure. It doesn't make better use of available light. It just captures more by reaching higher, making adjacent areas less valuable or even useless for further solar installations.

They suggest these towers and other configurations as useful for locations where available footprint is limited, such as urban areas. I dread the day when I start seeing such structures, erected by neighbours, looming over my fence and blocking out the sunlight to my patio, garden or my own solar collectors.

Pardon me mods, but +4 informative? This is a terrible summary from someone who doesn't seem to have understood what he's read. The novel "cloudy-thing" aspect of the article's argument is the very part the parent misses when he dismisses this as "nothing new".

The cloud is an abstraction that intentionally hides detail. Cloud providers do that to make the service being offered simple to package, sell and use. They also do what they can to keep the tricks of their trade secret from competetors. But their infrastructure is actually very complex relative to what the average small to medium client would need for themselves. This is important in three ways:

  1. 1) Your own engineers can't take all aspects of a deployment into account when making decisions.
  2. 2) As a moderately sized company, using the cloud will expose you to the risks of emergent behaviour that would simply not be an issue on the smaller scale you would operate on if you ran your own infrastructure.
  3. 3) Your system may be humming along smoothly one moment, then start thrashing disasterously the next in the absence of any action on your part and for no apparent reason, simply because your cloud provider has tweaked some seemingly innocuous parameter (even after extensive testing)

This is an important and novel issue and worthy of some real consideration.
