Conferences

JavaLand 2022

JavaLand 2022 is a wrap! This is one of my absolute favorites when it comes to conferences, and this year finally back to in-person after being online the last two years. A bit smaller than usual, but with 100% community spirit!

This year, I had two Jakarta EE talks included in the agenda.

Both the talks were located in the Arena de Fiesta, where the stage is made up of ice(!). There was a thin carpet laid out on the ice under the speaker stand, but I can assure you that it was pretty cold at the end of the talk. Didn’t actually help that the M1 processor doesn’t provide any excess heat during the demo either. Almost made me miss my old Mac…

In addition to these two talks, we also set up a Jakarta EE Panel Discussion to fill an empty slot. The panel was made up of Emily Jiang, Christian Kaltepoth, Rudy De Busscher, Werner Keil, and Jan Westerkamp in addition to yours truly.

The JavaLand organizers were kind enough to give Eclipse Foundation a free booth in the Exhibition Hall where we featured Adoptium and Jakarta EE.

The Jakarta EE Developer Survey 2022 is open, and waiting for YOUR input!

CodeMash 2022

CodeMash is a conference I always enjoy very much coming back to, so I was extremely pleased when they decided to have a conference this year despite all that is going on. It really shows that it is possible to arrange in-person events in a safe way.

If I should describe CodeMash in one word, it would be Friendly. It is an extremely good vibe at the conference. It does, of course, help that it is held in the conference center of an indoor water park. The organizers are 100% transparent regarding the organization, budget, and everything else.

CodeMash offers a mentoring program for new speakers. When you get a talk is accepted, you get the question of whether you would consider mentoring a new speaker or be mentored by an experienced one. Since I consider myself pretty experienced as a speaker, I signed up as a mentor this year as well.

I think mentoring programs like this one is an excellent idea and would encourage anyone offered to participate in one to do so!

My talk, Jakarta EE 10 is Coming Your Way! was scheduled for the last day of the conference. Actually to the last time slot before the conference closing session. Usually, I prefer to be scheduled earlier in the program, but I guess that’s how every speaker feels. At CodeMash they have a closing session with a raffle, so there is another incentive for the attendees to stick around rather than beat the traffic on Friday afternoon.

To sum up, CodeMash was an excellent start to the 2022 conference year and I hope to be back next year! I also look forward to speaking at lots of conferences in the upcoming months and meeting up with community members in the conferences-within-the-conference happening at meals, parties, and hallways between and after sessions.

Reflect, Relax, Recharge at Devnexus 2020

The next conference I will be attending is Devnexus in Atlanta which is organized by the Atlanta Java User Group.

This year, Devnexus is extended with a JUG Leader Summit scheduled the day before the conference where there will be more than 40 Java User Groups represented.

In my session, What’s going on with Jakarta EE, I will provide an update about the ongoing work with Jakarta EE 9. This talk is also an opportunity to come forward and have a dialogue about everything going on in and around the Jakarta EE Working Group at the Eclipse Foundation.

During the conference, you will probably find me around the Jakarta EE booth with Tanja when I am not attending talks by all the amazing speakers. Please visit ut there for an informal chat about open source or to pick up some of our Jakarta EE swag!

2019 Summary

It is time for my yearly summary of conferences and community activities. In addition to numerous local meetups and online events, I had the opportunity to speak at the following major developer conferences:

Jfokus, Stockholm
Devnexus, Atlanta
ConFoo, Montreal
JavaLand, Brühl
JEEConf, Kiev
QCon, São Paulo
DevTalks, Bucharest
Java Cloud Africa, Johannesburg
J4K, Orlando
Oracle CodeOne, San Francisco
EclipseCon Europe, Ludwigsburg
Trondheim Developer Day, Trondheim
Devoxx Ukraine, Kiev
Devoxx Belgium, Antwerp
Devoxx Morocco, Agadir
Java2Days, Sofia

The biggest change for me this year happened in October when I joined the Eclipse Foundation as the Jakarta EE Developer Advocate. This means that I am able to dedicate all my time to community building and contributions to open source.

My new role enable me to be even more present at conferences and events around the World, so I expect 2020 to be at least as busy. I already have conferences lined up for the first quarter and more in the planning.

With Jakarta EE 8 out the door in 2019, we are now in full planning for Jakarta EE 9. The biggest impact of this release will be the namespace change from javax.* to jakarta.*. We will also prune some not very widely used technologies in order to lighten the burden for new implementations of the platform. This work will probably continue in subsequent releases.

All in all 2019 was a great year for Jakarta EE and I expect 2020 to be even better!

Oracle CodeOne 2019

I am on my way back home from this year’s Oracle CodeOne. As always, this week is so filled with content and activities that it just flies by.

In previous years, I have always had the sort of empty feeling on Thursday (the last day of the conference); the exhibition hall and Groundbreakers Hub is packed away, lunch in the hallways, lots of people walking around with luggage just catching a couple of sessions before heading home.

This year was different. As Ed Burns said in the talk he held together with Phillip Krüger that he found Thursday to be the best day of the conference, to be able to just attend sessions without all the other distractions. And I agree! This year, I listened to great talks from 9 in the morning until 15 in the afternoon with only 15 min breaks between the sessions. No distractions, other than the usual short hallway discussions between the sessions.

and

Jakarta EE 8 was launched the week before CodeOne. Another important milestone for the community! We had a lot of great talks, BOFs and hallway discussions.

The general impression of this edition of CodeOne is that it was smaller than last year. Both in the number of attendees, but also the number of exhibitors. The community spirit, however, was as strong as always!

#OSSRRR at Devnexus 2019

Devnexus 2019

Devnexus 2019 is happening in Atlanta next month. This is truly an awesome tech conference run by the Atlanta Java Users Group and I am so happy to be part of it as a speaker for the third time.

My talk this year is a presentation of patterns commonly used in microservice architectures. Each of the patterns will be explained and demoed live using Eclipse MicroProfile.

Microservice patterns in Eclipse Microprofile

Another think I look forward to at Devnexus is to meet up with will all the people participating in Jakarta EE that are present at the conference.

The party theme this year is R3, which stand for Reflect, Relax, Recharge and is definitely the place to be to meet all the awesome community members, Java Champions and Groundbreaker Ambassadors present! Everybody will be there, and so should YOU!

There is a limited number of super cool t-shirts exclusively made for this party. One of them could be yours simply by writing a blog post!

2018 Annual Summary

It’s this time of the year again. Time for the yearly summary of conferences, travels, community activities, open source projects, amazing people!

Like most recent years, I have been speaking at quite a few conferences around the World. The countries I visited as a speaker in 2018 were Sweden, Germany, USA, England, Denmark, France, Belgium, South Africa, Australia, and New Zealand.

Speaker Appearances 2018

One of the highlights this year was to be awarded the JCP Outstanding Spec Lead Award together with Christian Kaltepoth for our work with JSR 371.

Getting the JCP Award for Outstanding Spec Lead 2018

Another acknowledgement by the community was to be re-elected for an associate seat in the JCP Executive Committee.

Besides speaking at conferences, a great deal of my time in 2018 was dedicated Jakarta EE at the Eclipse Foundation where I act as the PMC Lead of EE4J a well as being a member of the Steering-, Specification-, and Marketing Committees in the Jakarta EE Working Group.

All in all 2018 was an eventful year and I expect no less of 2019!

Oracle Groundbreaker APAC Tour 2018

This year, I was so lucky to get the chance to be part of the Oracle Groundbreaker APAC Tour 2018. The cities that I joined the tour was Perth and Melbourne in Australia as well as Wellington in New Zealand.

Perth, Australia

Copenhagen – (Singapore) – Perth
Gone swimming…

In Perth, I did a talk called Serverless with Java. I demoed various FaaS options available, including running Fn Project on Oracle Cloud. Between the sessions, I also managed to slip outside for a swim in the ocean.

Melbourne, Australia

Perth – Melbourne
New bush hat

In Melbourne, I had two sessions scheduled. The first was an informal Q&A with the local Java User Group. We had great discussions regarding the 6 months release cadence of Java, we discussed Jakarta EE and Eclipse MicroProfile and talked about Java development and Java user groups in general.

Later that afternoon, I did my Serverless with Java talk for a small, but an enthusastic crowd. 

Wellington, New Zealand

Melbourne – Wellington
Installing fn on OKE

The last stop on the journey was Wellington, New Zealand. Even here, it was the Serverless with Java talk that was put on the schedule.

To spice things up a little, I did a last minute try to get fn up and running on a managed Kubernetes cluster in Oracle Cloud Infrastructure.

I was close, so the next time I do this talk this will be part of the demos…

Wrap up

This was a fantastic trip, even considering the busy travel schedule and probably spending more time in the air or at airports than on the ground. The trip home from Wellington took ~36 hours door-to-door with short layovers in Auckland, Perth, and Singapore.
