I’ve completed yesterday the course Object-Relational Mapping with Hibernate: Hands on. Although I’ve already used Hibernate before, it was very valuable to refresh and expand my knowledge on the topic. I was quite doubtful whether to enrol or not, but I am now glad that I did!

Groovy Baby!

By stefano, on February 8th, 2012%

In the last few days I’m trying to learn Groovy, and until now is surprisingly easy. The great part is that it can access all the Java classes and libraries natively, but without all Java boilerplate and verbosity.

I’m starting to think to use Groovy instead of Perl for my scripting needs, for instance . . . → Read More: Groovy Baby!
