RTFP before you complain, it already addresses your concerns. The point is about assuming that disk write will be slower, when, in real life, some specific programs can be sped up by writing directly to disk. They mention that the OS takes care of disk buffering for you and note a lot of stuff that is happening behind the scenes in memory, especially with immutable strings in high level languages.

they have a DNA-sample . . . from the crime-scene, for which no matches exist in police databases. Currently they have to look for him the old-fashioned way — and the sample is only useful to (in)validate the people.

Unfortunately in this case, they did not use the sample they had to invalidate the suspect they wrongfully convicted, but instead came up with a theory on how three men assaulted and murdered the victim in her small apartment room and only one of them (the one they couldn't identify) left physical evidence.

Errr.... prices dropped because DEMAND dropped. And why did demand drop? Because consumption dropped

Wrong . . . Prices dropped because SUPPLY rose. And why did supply rise? Because prices rose enough to make hard-to-get oil worth investing in. So, don't expect prices to stay low when fracking investments, etc. decline.

if they sell at the local rates of ~14cents a kwh (24 in the winter) they aren't making any money by selling power to the locals because its really 14-24cents kwh for offshore wind, there is no profit margin there.

$0.14 per kWh has little to do with it. They are saving money because they can shut down the expensive ($0.40 to $0.50 per kWh) diesel generators that is their only current generating source. The cost of the wind power generated is well below that regardless of connecting to the mainland or not. Also, they plan to sell excess wind power to the mainland through the cable - that's wind power that would be wasted otherwise, so even at a losing rate of "~14cents a kWh", it's a gain to bottom line (assuming the cable is going to be there, anyway). If the cable to the mainland was the only valuable part of this, why wouldn't someone have financed the cable without the wind power?

You miss that it isn't like that in Windows either.

Actually, it is like the GP said: "On Windows, extensions are meaningful to the operating system." I get your point that the user and thier "trusted" programs can set what opens/runs what extensions, but the MS Windows operating system uses the extension to look up what program is associated with it and opens the file with that program.

Can you also tell me how do we renew the sun?

I think by modifying the photon torpedoes and launching them into the interior of the sun, you can bring a dying sun back to life, but you have to watch out for neutron drift. It was described on TNG, but I can't remember the details.

We're talking about analyzing a few sentences that were jotted down by an interviewer, but still, Mr. Nye's attitude is not so impressive.

Actually, almost all of the comments I've read so far are about the Slashdot summary, not the actual article. The actual quotes in the article are not quite as likely to stir up outrage as the misleading indirect quotes in the summary.
