Java DevRoom Schedule changes

For technical reason and in accordance with the speakers, I changed slightly the schedule.

The “Fortress” talk has been canceled, while I switched “Building an open Internet of Things with Java and Eclipse IoT” and “Java restart with WebFX“, and this last one will get a slightly longer slot:

12:30 – 12:55  Building an open Internet of Things with Java and Eclipse IoT
17:00 – 17:55  Java restart with WebFX

The full schedule is already online:

The schedule for the Free Java Devroom just appeared online:

I’m looking forward to enjoy this Fosdem, not only the Free Java DevRoom itself has lots of great content, but as it is usually the case the same can be said about most other DevRooms. It will be a very difficult choice to decide where to go and what to see 🙂

Free Java DevRoom Speaker selection

You can find the original announcement here

It was a very a difficult choice this time and it took a bit to understand the best schedule and try to get the most tracks.

This is the list of approved talks, in no particular order. Thanks to anyone who participated, unfortunately we were not able to select every one, and the choice this year was insanely difficult!

I hope the speaker who we could not select will still join us to enjoy what we are preparing for this year Free Java DevRoom celebrations!

FreeJava DevRoom – Call for Paper 2015

We are pleased to announce the Call for Participation in the FOSDEM 2015 Free Java DevRoom!

This marks the 12th year that the Free Java DevRoom has been a part of FOSDEM, and also marks 20 years of Java!

This year FOSDEM Free Java DevRoom will be 31 January & 1 February 2015 in Brussels, Belgium, with usual additional events and meetings on Friday, Saturday and Sunday; please, refer to the FOSDEM website for the schedule of the whole event:

The Free Java DevRoom has become unique in that it has attracted hackers from very different Free Software Java projects, giving the opportunity to bring together companies of various sizes, different project communities, mainstream core Java developers, alternative Java language implementations and runtimes, and everything that form the Free Java  Universe, everybody participating to share their knowledge in an atmosphere of cooperation and friendly competition.

It has been a long journey so far, exciting and fun, and hard at times.

But together we have made it, and Java today more than ever can count on a dynamic and vibrant Community, innovation due to participation, and a user base that is continually growing.

We won’t sit and rest on the paved road we built, though! We are eager to contribute to the next “20 years of excellence”, and we want you to be part of it!

As always, check out our wiki for more details on the conference:

The Free Java DevRoom Organizing Committee

Java Champion!

This week I received a very welcomed news, I have just been accepted as Java Champion!

Java Champions are a group of passionate Java technology and community leaders who are dedicated to the Java platform and the Community surrounding it, it’s not a big group in terms of people being part of it (although it’s growing fast), which makes it feel even more exclusive. I’m proud to be part of it, and I hope to be up to the task and serve this new responsibility with all the deserved passion!


Fiorenza Sofia :)

Fiorenza Sofia :)

On 19th of March the most wonderful and happiest event in my life happened, my daughter was born 🙂 at 17:16, in Karlsruhe.

Just in time for Fathers’ day, which happens exactly on 19th of March in Italy (not in Germany, so I can celebrate twice 😉

Everybody said that being a father is a life changing event. While I started to understand it already from those past 9 months, I don’t think I really got prepared to fully appreciate what it really means. In fact, Roman told me that you have 9 months to prepare and inevitably get unprepared to this appointment!

Indeed, and it is really beyond description, but I feel so proud and happy, and scared, all the feelings are mixed up… but above all, I feel full of love, it is so wonderful to look at her smiling (and she does smile a lot!), a warm sense of calm and peace and happiness goes all around, the air is pregnated with it! Everyone should experience this feeling at least once, the World would be so much a better place, I think.

Anyway, it’s time to go and look at her now, she grows so fast and I don’t want to miss not even a minute of her life!

2 years at Red Hat!

Tomorrow marks 2 years I’m at Red Hat, and it has been so far a very exciting journey, for one of the most interesting and awesome company around. I’m glad I’m here!

Only problem is that I started on 29th of February, and tomorrow is actually 1sth of March… so I need to wait two years more before I can celebrate even the first year… ouch 😉 But at least I’ll be able to do a very awesome party by  then!
