It's intented to be an index with interest links and docs. Code As you probably know, I like to code a lot. Here I put some pieces of code that I think are useless, but if you can give them a nice touch then you can use in your own apps. It's language categorized. Enjoy as much as I do.

Anyway, he said to that I try to make Ruby natural, not simple. It's one of the languages that I fall in love and never let go away(yes, C is the another one).

Really, I don't like so much, but it's so much easy to learn and use and, as a friend said once: Java it's a big Lego's box, just put the pieces together and it works!.
