Weekly roundup: going to Barcelona

I'm leaving for Barcelona on Thursday afternoon for the PHP Barcelona 2011 conference and I will hold my talk on the Pomodoro Technique on Friday morning. Feel free to ping me if you will be there, I like to discuss about the themes treated in my writings. :)

These are my original articles published this week on DZone.
