What you're saying today is: "It definitely hasn't happened yet." And tomorrow: "It definitely hasn't happened yet." And the day after, if we just happen to see it: "It definitely happened 600 years ago."
It doesn't matter whether we have observed it or not, it might have happened already.
You might want to read a bit about light cones. An event is considered to have happened in a frame of reference when information regarding the event can reach that frame of reference. So if we see it go boom at 12:00 tomorrow, then in our frame of reference it went boom at 12:00 2009-06-13. Not 640 years ago, even though it took the information regarding the event that long to reach us.
Relativity is cool like that. It is _not_ intuitive!
In our last vacation, my four-year old spent at least 30 minutes staring up to the night sky with his mouth open...
I know what you mean. I took our daughters camping just a month ago, and the 2.5 year old asked what all the lights in the sky were. Despite that, being _my_ daughter, she was able to identify the Big Dipper and find Polaris, by herself (thank you Stellarium)! That, at two and a half!
Exactly "like" a repository. The difference being that Joe Shmoe hears "repository" and knows that it's some technical thing that will confuse him. But an "apps store"? That will have what he needs!
does it make any sense to talk about an object being stationary wrt a region of spacetime? if yes, then what is the relative velocity of an object that is stationary in one of these spacetime reference frames with respect to another object that is stationary in the other spacetime reference frame?
Once users are held responsible, ISPs will be held responsible - not only for the damage their users do, but also by users for letting malicious traffic to the user's computer.
Hey, that's a great idea! We should have the ISP filter our web traffic, to keep us safe. Government mandated!
I recently called Logitech asking if the MX would work on Ubuntu, as it is not stated on the webpage. The tech said no, in fact, Logitech does not make any mice that work with Linux. Then I called Microsoft and discussed the Wireless Notebook Presenter Mouse 8000 with the tech. The MS tech was very helpful and I'll be receiving the mouse in a few days (ordered on the 'net).
As crazy as it sounds, Logitech has no interest in selling Linux users it's hardware. Therefore, I have no interest in giving them my money. Microsoft, on the other hand, was very helpful and professional. They earned my $60.
I don't know of a single modern case of malware being in "trusted" repositories (such as Ubuntu's main repository, etc).
Not Linux, but FOSS: Recently the Thai translations of Firefox were infected with malware. I forget the details, but it was on slashdot. However, it does seem to be a very isolated incident.
Of course, I should have anticipated the result: there is unfortunately insufficient data to estimate the velocity of an African swallow (even if you specified which of the 47 species of swallow found in Africa you meant)
You make a good point. If you are doing ground-breaking research that depends on computer calculations, how can you be sure that the results given to you by mathematica are accurate and not a bug? Reworking the calcualtions by hand defeats the purpose of using the software in the first place, if that is even possible (some physics simulations take weeks of _computer_time_ to compute).
At least with open source computer algebra, one can verify the method used to compute the results.
I'm waiting for the day when some/.er with a UID an order of magnitude above mine corrects me with: "Sorry, grandpa, computers have not had hard drives for over 10 years"
For anyone who seriously uses Excel, there is no comparison. I just gave Calc a serious try, and I gave up after a week.
Please, please document your findings and either file bugs and feature requests at the OOo issue tracker, or contact me and let me help you file the issues.

Fourtheded. And even with the tabs on the left side, and the Kubuntu panel on the right side, most webpages _still_ cannot fill the remaining width of the 1680x1050 screen on my laptop. To get even more vertical space, I put the menu on the same toolbar as the addressbar, and a few icons as well. Oh, and Vimperator. I love Vimperator: http://vimperator.mozdev.org/

How is this insightful?

That's cool for your kid, but what about the kids in the southern hemisphere whom will never see Polaris?
They're more than welcome to visit! We're a two hour drive from the international airport. Exercise to the reader which airport that is!
And no, I don't know what that is in the metric system
American Degrees are called "Degrees" in metric. The conversion factor works like this:
American Degree = d'
Metric Degree = D
D = -(d' * e^(i*pi))
All the new convenience stores they've built that shed all the light, also stock Milky Way. I prefer Snickers, though.

Perhaps there's a super-duper evil genius right now who is plotting to kidnap his mother to turn him into a revenge-motivated evildoer!
His mother is from Taiwan, they are nice people. It's his father who is the Jew, and therefore hated by all!

European or African stationary object?

Actually, this has already been done. The Pioneer Plaques gave the location of the Earth, as relative to pulsars:

Why? I still drive a vehicle that was manufactured in the '60s.
Yes, but how many times has it been serviced since? How many parts replaced?

Wow, you sure asked the wrong question:

Of course, I should have anticipated the result:
there is unfortunately insufficient data to estimate the velocity of an African swallow (even if you specified which of the 47 species of swallow found in Africa you meant)

Mustangs have not had distributor caps for over 10 years. Each pair of cylinders has it's own coil.
Well then you better just wake him up!
Go download Orbiter and educate yourself.
When it runs on Ubuntu I will.
.. if they launch Endeavour to rescue Atlantis, and Endeavour suffers damage at launch?
Then they bring out the gimp.
Haven't seen any stories on the U.S. news websites.
Then why all the bitching that /. is too US-centric? Or is "News for nerds" not a news website?
By the way, opening yahoo news it was right on top:
