really ?
looking at _production_ cars:
Toyota Prius from 2009: drag coefficient: 0.25
Tatra 77a from 1935: 0.21
Rumpler Tropfenwagen from 1921: 0.28
the late 30ties were actually the high point in aerodynamics being the focus in automobile manufacturing: there are countless of other examples from the time which simply never made it into production because of the war:
like the BMW K1 prototype which also achieved a value of 0.23 despite being a full 4 door saloon
another interesting car: the Fiat Turbina prototype: which had a coefficient of 0.14 (a record for 30 years) but any further development shelved because of problems with the expieremental fuel gazzling overheating turbine engine ;)
Thanks! That was fun following up on some of these early cars. Some of them are just gorgeous. It is amazing and inspiring that engineers working with slide - rulers and wind tunnels (and without fancy computers) could achieve the same kind of drag coefficients on their designs that modern supercomputers can come up with.
However - I still think my point stands ("Steadiness"). While small production cars may have been aerodynamic - the industry average was not. In fact I could argue that as engine efficiencies improved, industry wide, aerodynamics got worse because the overall mileage stayed much the same (or improved slowly).

I'm beginning to believe the term "sentient mammals" is more appropriately applied to dolphins than humans. At least the (R) kind.
Dolphins aid dog rescue (http://www.upi.com/Odd_News/2011/02/25/Dolphins-aid-dog-rescue/UPI-77461298624400/)
MARCO ISLAND, Fla., Feb. 25 (UPI) -- A Florida woman said her missing dog was found after a group of dolphins drew a neighbor's attention to the canine treading water.
Cindy Burnett of Marco Island said Turbo, an 11-year-old Doberman, escaped from her yard Sunday night and she and her sons were unable to locate him, WBBH-TV, Fort Myers, reported Thursday.
Burnett said a fatigued Turbo was finally spotted swimming in canal water when a group of dolphins splashing loudly drew a neighbor's attention to the distressed canine.

I think some people here think this is suddenly going to allow us to drag an image from our desktop to the .Mac mail page, and attach it to a new message. That isn't what they are describing as "drag and drop". They are talking about moving messages around in the web browser window.
I feared as much, still being able to select multiple files in one time to attach would be enough for me, or just wait to upload until you are done

Do you really think there is a limit to how much storage people want? People would rather shuffle more songs than less.

All this stuff about "living under mum and dad's roof" is all well and good but it's not gonna work.
The guy is 18 and therefore you have no say in it. If you want to show him you trust him, make sure he is having safe sex (ask him "are you using a condom" - don't beat around the bush, it's sex, it's not anything to be ashamed of) and send him on his merry way.
It's time to let him make his own mistakes and decisions and the best thing you can do is to love and support him through it all. I was a good teenager, same sort of thing as your son - good grades (not that these mean you're a good person), nice friends, stable ideals but I found the sudden leap into adulthood one of the hardest things to do because I was suddenly in charge of my own life. My parents - though they vehemently opposed some of my decisions - supported me through them no matter what and that helped me to realise for myself my own interpretations of right and wrong and allowed me to grow as a person.
So don't treat him any differently, just make sure he knows the facts and is not doing anything unsafe, and let him go. There's no reason you can''t voice your disapproval but make sure he knows that this is his call and that you love him no matter what.

Opera will zoom entire pages, very useful for resizing tiny little thumnail photos or huge images too big for my hpvs17 monitor... if it can be done, why isn't Apple on top of it?

Maybe the reason they didn't bring it up was because they are working on a new feature (ie new maps or turn by turn gps built into the next iOS; they did mention it was to collect data for something like that), but now that the media has blown it out of proportion, they had to come out and address it. At least, that's what I'm assuming Apple's point of view was.

No. If you take a life, you get to sit in a small dark room for 23,5 out of 24 hours of each day for the rest of your life. You will not be able to kill yourself, you will have to endure the absolute solitude. (EDIT: This is pretty much only for premeditated stuff, if you ask me)
Why?
A rope, chair and ceiling hook should be provided, on the chance that you don't like the accomodations.
Even one example of someone being killed by the state for something they did not do invalidates the whole edifice of capital punishment.
Yes, we've been over this ground before.
See, you're winning me over. ;)

Weren't they made aware of this almost a year ago? That's a long time to address an oversight.
Actually the recent news about the location db is a completely unrelated issue.
1. Apple does collect location data in order to improve their location services. This was long ago disclosed to regulators and users. This is NOT the target of the recent media buzz.
2. Your phone dynamically creates a local cache of known cell tower locations in order to aid in GPS triangulation (the "a" in aGPS). This is the recent hot topic and has been grossly misrepresented by the media. (Apple does not collect this data, because they sent it to you in the first place)
