I invite you to the 2nd Cluj Pythonistas meetup where two of the best Python developers I know will tell you about subjects that they love:
Celery introduction - Ionel Maries
Zope Component Architecture - Sever Banesiu
The event's host is Cluj Cowork and the recommended contribution for that is 10 lei. See you there ...
P.S. ring at "Ruby tribe" when you arrive.
