that's close to Belgium and Netherlands legislation then

If anyone manages to grow that bonsai thing, he'll become a new God :-)

4. Nuclear plant (Tchernobyl, Three Mile Island)

Fixed that for you ...
I'd rather see nuclear plant used instead of coal or oil-burning plants, but please don't ignore the potential danger(s)

And can you grown your own cannabis plant ? (legally speaking)

again ethnocentrism ...

for the use of social structure : what about sharing ideas and knowledge (to invent new things like interstellar travel ...) ? unless you need to have sex to do that ?
if your whole life turns around having a bigger penis/car/house/bank account/boat than your "concurrent/neighbor", I truly feel sorry for you ... but then I understand that you might be afraid of E.T. penis/car/house/bank account/boat/laser beam/gamma rays/superduperspaceship

Besides you're talking about "false assumptions" from others but yours are not any more valid ...

Well it depends, we (20-21st century humans) are ill-adapted to live if we were to live 100.000 years ago and my place and life is pretty much Eden-like compared to what it would have been then. I don't need to fight for survival (yes I'm aware that I'm part of a privileged part of the population and that it might change any time).
... See you in another 100.000 years to compare with 1021st century boys :-)

NB: Personally I don't believe in E.T. visiting us and even if they were to, I'm just telling that we have no idea whether they would be dangerous or not.

one word : curiosity

And as far as we (don't) know, their technology could be extremely non resource-destructive (again, ethnocentrism : "because we human are very resource-destructive, every living thing in the Universe should be" ;-) )

And what possesses you to believe that if a race of beings with super-light travel actually exists it would act as human beings ? (trade or conquest).
That's called ethnocentrism and it's as wrong an assumption as the "peaceful ET" hypothesis.

what about duplicity ? (incremental snapshots, command-line tool, librsync-based, used by "deja-dup"), rdiff-backup and rsnapshot

I just noticed that on Ubuntu (and I guess every recent Gnome) the file's size/hard drive occupancy are indicated as "KiB", "MiB", "GiB" while XP displays in KB, MB & GB (but using the base 2 of course).

How long has it been that gnome (and the others ?) displays the "iB" instead of the "B" (or was it always that way) ?

Why the query

doesn't return Yahoo ?
actually it doesn't return any result ...

In the beginning was the command line,
then they invented the GUI to make it easier to use that command line
then they invented the command line to make it easier to use that GUI
then ...

I'm Belgian you insensitive clod !

(and it's less than 50% by the way)

you just forgot that some people cannot detect sarcasm :-) http://science.slashdot.org/article.pl?sid=08/12/15/1629245
