Adjustment does not change the beam *pattern.* Some round ECE headlamps that go into round holes meant for DOT sealed beams, as I understand, can be rotated so their kickup goes to the correct side, but not so for Z-beam type dipped beams. Google "ECE beam pattern." Obviously, most any composite style headlight cluster can't simply be rotated.

Air has a surprisingly high specific heat. It just has a low density.

Most of the stuff I (consciously) put in my fridge doesn't spill out as soon as I open it, either. Cold air does.

My back-of-the-envelope calculations put the energy required to rechill a typical refrigerator's airmass by 20K is in the 10^5 J range, or around 3 watt-hours.

So why the fuck would anyone want to be on facebook?

People who can think more than 5 minutes ahead don't want to be on facebook, and they aren't. However the majority of people only care of "now", even if that much. They post a message or a photo because they can't be bothered to think what it can cause in the future.

To make things worse, it generally hurts your privacy to have a social life these days. Even if *you* didn't take the photo and didn't post it for all to see, someone else - out of tens of random people you met - can do so and attach your name to the photo, all that without you knowing. And that's how the data trail grows.

Even on /., formerly a bastion of near-paranoid sysadmins, posts appeared (a few years ago, IIRC) saying "the war for privacy is lost, so abandon all hope, drop all defenses and have fun!" And there is indeed a serious push to abandon all hope because it takes more and more effort with every passing day to keep your privacy, and it certainly puts constraints on how you deal with your friends and how you participate in social events. I do not expect majority of the population, especially teenagers, to sacrifice that much at cost of what they value most [at the moment] - their friends and their social life.

Cyber-criminal Left In Charge of Prison Computer Network 389

samzenpus writes "A 27-year-old man serving six years for stealing £6.5million using forged credit cards over the internet was recruited to help write code needed for the installation of an internal prison TV station. He was left unguarded with unfettered access to the system and produced results that anyone but prison officials could have guessed. He installed a series of passwords on all the machines, shutting down the entire prison computer system. A prison source said, 'It's unbelievable that a criminal convicted of cyber-crime was allowed uncontrolled access to the hard drive. He set up such an elaborate array of passwords it took a specialist company to get it working.'"
