Thinks I've learned:
* makeing GUI is not that difficult
* WebDAV is an easy way to export any filesystem like structure
* how to hire a XSLT developer
* not that TIMTOWTDI but there are unlimited ways how to do thinks
* that the Excel "hammer" is everywhere
* that there is Parallel::Iterator that looks simple and useful
* HIPPO => HIgh Person Pay Opinion
* never guess or assume or even ask for what people like, but test it
* XML::XSH2 is really cool to manipulate the XML files
* there are Perl developers hidden all around
* anything than can go wrong, will. anything than can not go wrong, will. -> just don't worry and take it easy
