[erlang-questions] OT: Please highlight me about JAVA C++ as high level languages just like erlang.

[Angel]

Thanks Michael, and all people.

Definitely (just for helping newbies choose where to spent their time)

My vision about computer languages is something along this:


- Wassup men!! ¿i have some spare time You know? , Im considering learning to  
program computers!! Now boy, come on!! tell me whats best language!!!

- Sure!! Leptons is your color!!! that kinda funny lang men!! the best!!!! 
trust me is damn fast, bare metal ¡¡you know!! zwwwipppp!!

- So fast!! i can't wait

- Sure dude, all people know leptons!! They do!!! I almost spent last two 
months hacking a kind of thing i call STRING!! is cool, millions and millions 
of leptons, muons and mesons you know!

-- Gauu i see, im impressed!!

- Sure!! da thing its cool, so i managed later to make still more milliion of 
them and make atoms!! yeahh i tell you, those BIG atoms allowed me to to logic 
gates!!! 

- Macho macho men !!

-Wait!!! its not the end, those funky gates... store bits!! and some of them 
bytes...

-IM DISMAYED!!

-Take easy men,!!! you'll learn this soon!! so i managed again to make 
caracters to make words!!! trust me, i dont cheat!! and  ITS BLAZING FAST!!!

 
- You are the ONE guy!! i almost go wrong on trying to learng BRICKS..

- BRICKS!! Are you mad!! this is for academic freaks nobody else will even 
think using it!! Hear me, it  is no way men HOUSES!!! what's that? almost all 
you can make with this are HOUSES terrible boring.

- Yeahh, full of shit!!! i saw they have also electric outlets!!...

-Yeahh men you told it ¡¡SHITTT!! 

¡¡¡OUTLETS!!! 

what is cool....

... is to make the electrons yourself!!

Sorry for my english!!
