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.

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.

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.

#JavaOneStreak revamped to #GetFitForCodeOne

The last couple of years, we have been running a concept called JavaOneStreak the month before JavaOne. Since JavaOne is history, and the event replacing it is Oracle Code One, it makes sense to renew this concept as well. 

The original JavaOneStreak was to run a mile a day for in last month before the conference and tweet about it using the hashtag #JavaOneStreak.

For this year’s Oracle Code One, I want to expand the concept to include any physical exercise.

How does it work?

1. Work out (yes, you have to get out of that chair!)
2. Log your move using your favorite activity tracker (e.g. Endomondo)
3. Tweet about it using the hashtags #GetFitForCodeOne and #CodeOne (for extra exposure)

If you join the challenge on Endomondo, you will get listed below:

JavaOne becomes Oracle Code One

My first JavaOne was in 1999 and I have attended almost every one since then, first as an attendee and since 2013 as a speaker. Attending JavaOne has always been one of the highlights of the year. This is where the community meets, announcements are being made and plans laid. I don’t think this will change even if the JavaOne name is replaced by Oracle Code One as was announced yesterday.

https://blogs.oracle.com/developers/javaone-event-expands-with-more-tracks-languages-and-communities-and-new-name

The most important aspect of JavaOne has always been the community and the people. It is kind of sad that the name goes away, but I am confident that we will be able to embrace Oracle Code One with the same community spirit as we did with JavaOne.

Summing up 2017

2017 was an amazing year for me with a lot of speaking engagements at conferences in four different continents!

Per Lilja joined me in leading Javaforum Malmö and we managed to meet out target of four meetups each year. We are always looking for speakers, so don’t hesitate contact us if you want to present at one of our meetups.

Toward the end of the year, the EE4J PMC started up the work. The most pressing issue right now is to find a brand name to replace Java EE. Hopefully, this will be finalized in near future.

Stay tuned…

 

 

JavaOne Streak 2017

JavaOne is only one month away and it is time to get out of that chair and start moving! That means that JavaOneStreak is on again for the fourth time in a row. The JavaOneStreak initiative was originally started by Arun Gupta back in 2014.

Do some kind of physical activity each day during the month* before JavaOne, log it and share with the hashtag #JavaOneStreak.

You don’t even have to go to JavaOne, but tell us if you are so we can meet up and brag about our achievements.

JavaOneStreak 2015 – Leo, Heather and Ivar

*Of course you don’t have to limit it to a month. Try to follow Heinz’ example and run a mile every day year long.

JavaZone 2017

I am very happy to be back at JavaZone in Oslo this year with a talk called MicroProfile – by Example. In this talk, I will describe the history and reasoning behind the Eclipse MicroProfile initiative, provide code samples and strategies for using all implementations and also introduce the newest addition to MicroProfile – MicroProfile Config.

Of course, there will be lots of demo and code…
