Weekly roundup: speaking at PBC 2011

There is no official schedule yet, but speakers are beginning to confirm their presence to PHP Barcelona 2011. I will be there, with my talk on the Pomodoro Technique, a time management tool inspired by eXtreme Programming/Agile methodologies and widely diffused also outside of the software development field.
I also have seen confirming Juozas Kaziukenas, Stephan Hochdörfer, and Marcelo Duarte from iBuildings. See you all in October in Barcelona!

Meanwhile, here are my original articles published this week on DZone.

The goal of course, is to make a comparison with native mobile applications.
