Devoxx France, 1st Edition

DecoxxI was in Paris end of last week, attending the first edition of Devoxx France, a Java developers’ conference.

Devoxx is a well known and highly attended Java developers conference that takes place late fall in Antwerp. The French version has been initiated by the Paris Java User Group and has a similar structure but with 75% of the talks in French.
For a first edition, Devoxx France 2012 is a real success. Sold out 2 weeks before the event, over 1200 persons attended the 3 days’ conference. Yet, the conference felt human.

I was there only for the second and third days, as an attendee and as a co-speaker in the BOF session about Open Source Software in France.It was also the opportunity to meet and discuss with other developers, open source project leaders and potential customers.

Out of the talks that I’ve attended, I preferred the ones that were quite low level. Among them, 2 around hacking the JVM and the bytecode:  

I also enjoyed 2 presentations by Alex Snaps, one around concurrency and the CompareAndSet method. The other one about SizeOf or the difficulty to compute the exact size of Java objects, in order to improve large cache efficiency and management. I shall look at the ehcache project code, to see if we can leverage some of it for OpenDJ caches.

Also worth mentioning, 2 greats keynotes on the Friday morning with Pat Chanezon and Neal Ford.

See you next year at Devoxx France 2013, and may be in Antwerp in November for Devoxx (WorldWide)

And if you still hesitate, here’s a couple of quotes from the people involved in the review of the materials :

“Firstly, I’m pretty blown away by the quantity and quality of the material. It is extremely impressive, well done! :-)”

“Hell, this is going to be a GREAT directory server course!”

OpenDJ Training in Paris Jan 24-27 2012.

Material Cover Page.The OpenDJ Administration, Maintenance and Tuning (FR-462) training is taking place in Paris from Tuesday January 24th to Friday January 27th 2012.

The course is mix of lecture and labs and is designed for system administrators, integrators, consultants, architects and developers that will be installing, configuring, administering and maintaining ForgeRock OpenDJ LDAP directory server. I’ve been reviewing the course materials, and I must say I’m really excited by it. The amount of information available in the materials is huge, and the hands-on exercises are very detailed and practical.

The training is definitely a must for anyone who is or will be deploying and managing OpenDJ. And as this is the first training for OpenDJ in Europe, I will be attending it as an observer, gathering feedback on both product and course, also possibly as an assistant to the trainer Bill Nelson.

The session will be hosted in Astec training facilities, right in the heart of Paris, close to Gare Saint Lazare and Boulevard Haussmann.

There are still some slots available, so enroll quickly by email to training@forgerock.com.
