Global warming appears to be a serious problem. However, I think some of the proposed solutions would only make things worse: for example, people are encouraged to drive less. Which means either walk, or bike, or take public transportation. Walking is often unrealistic: while yours truly does walk to work, many people live too far from the office to do that. Public transportation is in premature state in most of the US cities, which leaves one thing: biking.
Biking is all good and healthy, but nobody seems to think about methane (aka fartgas). Intensive exercise, like biking, by millions of people will lead to excretion of millions of tonnes of methane, which is, as I've heard, a more potent greenhouse gas.
On the other hand, if harvested, all that methane can be an additional renewable power source - may be it won't be enough for transportation, but it probably could recharge your cell phone. Alas, we hear a lot about how good biking-instead-of-driving is, but next to nothing about the dangers of unharvested methane, which makes one think this is an elaborate conspiracy.
I am not that naïve and easily distractable to believe this is done by some out-of-space (knees-back) aliens who want to make the climate warmer for their liking. No, this is done by humans and most likely, by those humans that live in cold places - think Nunavut, or Franz-Joseph Land. They have thousands of miles of beaches but alas, its too cold there. No ladies in bikinis, no muscular surfers - only white bears and polar night. By warming up the planet they want convert their endless icy plains into prime real-estate!

Commuter rail stations conspiracy
(Or, actually, this is more of an anti-conspiracy).
Commuter rail cars have doors on both sides, because on some stations you exit to the right, and on some - to the left. However, there's often no need to differentiate which side of the platform the train arrives at.
Clearly, it may be more convenient to do one way or another in a city streetcar system:
- stations raised above the ground have one platform, trains arriving on two sides - this design needs only one set of elevators/stairs down to the street level;
- stations that are on the street ("stops" would be a more appropriate name for those) don't need any special ways to get from the platform to the sidewalk and therefore the platform is on the right side of the train.
However, inter-city commuter rail systems, like BART, usually don't have a stop just in the middle of a street - not only because such transit systems usually require a huge parking lot, but also because a 9-10 car train would create quite a traffic distraction if being let loose on the open street. So, as BART stations are already full-fledged stations, using up a lot of land, it would seem strange that some stations have one platform in the middle and some - two on the sides.
Therefore, as it would have been easier - and cheaper! - to build each and every station more or less a copy of others, I can only conclude that varying station layout is intentional, and, as the side of the upcomming exit is not announced, I can only conclude this is done to catch spies. See - a local would know where the exit is, while a spy, no matter how good he is at blending with locals, would not. There are cameras right above each exit on BART, so interested authorities can monitor those who hesitate, or prepare to exit through the wrong door, and then do a background check on them. It's OK if that was just a guy who moved into the area recently, but if that was a member of a foreign diplomatic mission, who is, according to the official consulate's schedule, supposed to be at a trade meeting in another state, then something is obviously fishy.

Better than average
They say 80% of the drivers consider themselves better drivers than their average peer, which is somewhat unlikely, unless the average is really, really bad. A usual explanation for this is that most people are over-confident about themselves and thus overestimate their skills and abilities.
However, another possible explanation is that it is hard to imagine an "average" person - as in off the pool of everyone. I think most people just imagine some random people who have cut them off, or even had an accident, or a near-accident with. Plus the respondents may remember some of their friends or relatives who drive really badly, making the respondent swear to never get into the car with them driving. And as very few people remember every single trip that went well, but most remember accidents or near-accidents quite vividly, it isn't surprising that when building up a picture of an "average driver" people mostly remember a set of bad* drivers and, often quite correctly, rank themselves as better ones.
*And even the best drivers may get into someone's "bad driver" list, because not everything is under the driver's control. A child runs unexpectedly onto the road, you slam the brakes causing the guy behind you to perform emergency braking, too, cursing you for not paying attention to the road. Perhaps he didn't even see the child, but it is you whom he'll blame for his scare moment.

Text-editing trick
Undo/Redo keys can be used to quickly go back to the place in the text where you've been. Like if you scroll up to where the #includes are, press Ctrl-Z and then Ctrl-Shift-Z to jump back to the place in the code you've been modifying.
Works with Office, too - although unfortunately the newest Word either doesn't have a Redo hotkey or something else is not quite right. A positive thing about the newest Word's hotkeys is, however, that they've kept the Ctrl-P to print, otherwise I would know how to print.
But the trick works where I do most of the text editing: with Visual Studio and I think I got it to work with Eclipse, so - w00t.

When I grow up, I want to be a...
Some people buy their children toy airplanes, thinking that may be some day kids will become pilots. Some people buy their heirs erector sets, slightly pushing them to become engineers. But of course, those are only hopes, not guarantees, and some parents just have to be certain, even if it means aiming low.

USAF Ad
I've seen an interesting ad for USAF on some website recently. It was made as a flash mini-game, stylized after an old arcade with an airplane flying bottom to top (or, rather the terrain moving under it), with some green squares moving towards the plane. I was even going to shoot some of these green squares, but turns out, the game is not about shooting the crap out of things (the whole purpose of an air force, I think), but you're supposed to "drop humanitarian aid", green squares are the targets for the aid.
They must have an urgent need for pacifists for some reason :)

How to get a new car using a cell phone.
Pretty simple - if someone yakking on the cell phone smashes into your car, totaling it, their insurance would pay for a new car. The problem didn't specify you have to use the phone, did it?
