Hey Professor Vagner, Why not using google project hosting or http://pastebin.com to post your code examples and simply link to them in your posts ? It's nearly impossible to read code in a font face that's not monospaced (not to mention indentation and syntax highlighting).
I'm sure your code snippets would be much more appreciated that way. At least I wouldn't have an instantaneous gut reaction to dismiss them because of the utter torture of reading them without any syntax highlighting and correct indentation.
