This can be a really big time waster! That's why we like it, right?
What is this ?
You're reading my weblog. As it's being used with different intentions, this blog is trilingual. Posts about my life, travelling and other topics are mostly written in portuguese but ocasionaly also in english or italian. Research posts are written in english. Sorry for the mess, I'm trying to figure a way to automagically translate the content. Meanwhile, try to sort it out with the tags.
