I admin a very relaxed and nice group: aeiou, which I consider nice because of the beautiful pictures of the group members. I also suggest you to read "The original sin()" (see below).

The original sin()

Shortly after the creation of the Earth and the Universe, the young Adam was roaming in the garden of Eden, when his attention was kept by a tree.

- Wow! So stunning piece of art! - he said.

- Just look, but don't touch. - a voice behind him pointed out.

Adam turned back his head. A penguin stand there.

- Are you God? - Adam asked surprised.

- Nope, only the Linux administrator. The tree that you see there is the tree of the sin().

- Tree of the sin? I've already heard about it.

- No. - corrected the penguin - Use the appropriate bracketing in the typewrite: that is the tree of the sin(), and close to it, in particular pi/2 offset, look, that's the cos() one. If you divide them each other you will obtain the tan() tree.

- And if I touched it, you would kick me out of here, right?. - Adam hazarded.

- You got a woman, Eve, to entertain each other and take your nose away from this stuff. Do you want to test the rage of God? - the penguin frowned.

- I won't do any harm. I mean... Why rage? Is that a creation of him?

- No, those module were created by the C++ compiler, but they are so important to God because with the sin() and the cos() you can describe many properties of Nature in terms of Fourier transforms, you know... and that can make life much easier.

The same day, but later, Adam was staring at the two touch-prohibited trees, when Eve arrived all legs and elbows.

- Howya, Eve! What's goin'on with you? - said Adam.

- You wouldn't guess! - Eve panted - I run to you, I'm dying to show you something way amazing! - she showed what she was hiding behind her back.

- Wow! That's a laptop! - Adam argued. - How did you get it?

- That's not only a laptop, that's an Apple. And you know what? I can get access to your beloved permission-denied tree...

- Great! - he said excited.

The following morning a deep voice awoke the two youngs.

- You dumb reckless! Do you have any clue of what you made yesterday?

- What a dreadful lizard! - Eve yelled.

- It's not a lizard, it's a chameleon. - Adam pointed out - Are you God?

- Nope, I'm another Linux administrator. - the chameleon said - And you are in big trouble: you messed up the sin() and cos(), you know? Somebody is very upset with you.

- Who, God? - he asked.

- No, the C++ compiler, God is simply furious and you will be kicked out.

- She is the guilty! - he pointed his finger. - She offered me the Apple!

- No, I'm not! - she replied - The Python gave me the Apple!

- Impossible! - the chameleon interrupted her - The Python and the C++ are best friends. That was surely a bug.

In that moment a huge foot shoved up.

- Hi there! - the foot said. - I come to kick you out, guys.

- Are you God? - Adam asked.

- Nope, I'm another Linux administrator. - he answered – You:

a) abused of the root privileges;

b) you called my colleague lizard;

c) you insulted the Python;

d) you probably thought that my other colleague (the penguin) is fat and that I stink.

Now you are condemned to use other systems, not a free software as i.e. Linux, but one full of fees, that will think for you, but not do what you do think, e.g.:

a) the text editor will (wrongly) correct the words that you type;

b) you will need rivers of sweat to do numeric computation or table representations or functional plots, the system will drive you mad by changing (for you) the layout every 5 seconds;

c) you will have tons of background (useless) processes slowing down your CPU;

d) the anti-virus software will start exactly during a presentation of slides;

e) random softwares will start when you don't even imagine (and want) e.g. the helper, which will change (for your happiness) the layouts and the settings and the tools, etc.;

f) different applications won't be able to recognise the same files: e.g. if you save a JPG file with an application A (e.g. a JPG editor), the application B (a JPG editor as well!) is not able to support such file;

g) the only way to kill a stalled process is not even by pressing Ctrl+Alt+Del, but by shutting down the electricity of the entire building!

Now say good bye to the Eden, say “Hello world!” -

And the two guys got a tremendous kick.

I'm very polite and Float64
