We Are Developers in Berlin is a massive event! It’s been a long time since I have been among so many people in one place. This would be considered a big crowd even by pre-pandemic standards.

My talk Get Ready for Jakarta EE 10 was scheduled as one of the first talks on the opening day of the conference. It was well attended, and those I talked with after the talk were happy and appreciated it.

We Are Developers is a polyglot event catering to a larger crowd than the usual more Java-focused events. Still, there were a lot of familiar faces. It was great to catch up with old friends and meet some new ones.

One advantage of having a conference in a big city like Berlin is that there are loads of options for what to do when not present at the venue. I spent a couple of hours in the Berlin Zoo before my flight home, and there I came across this fellow. Is it Duke in disguise? Has he lost his red nose? After a closer look, I can assure you that Duke is fine, and this is just a baby panda enjoying a nice chunk of bamboo for breakfast.

JNation is an awesome, community-focused conference located in beautiful Coimbra, Portugal! More than 800 attendees showed up for this one-day event. You can see a majority of them up on stage after the opening keynote in the image below.

This time, I was accompanied by Tanja on stage. In our talk titled Jakarta EE 10 and Beyond, we gave an overview of a selection of specifications included in Jakarta EE 10, as well as a sneak peek into what to expect from Jakarta EE 11.

Take a look at the slides from the talk if you missed out on our session.

As I promised in Hashtag Jakarta EE #126, here is a short recap of my weekend in Istanbul and Java Day Istanbul 2022. The eighth edition of this conference had an online part on Friday, whereas the main conference day was in-person on Saturday.

Traffic in Istanbul can be a challenge on weekdays, so it is a good strategy to have the conference on a Saturday.

I did a talk titled Jakarta EE 10 – Feature by Feature where I went through the new features introduced in Jakarta EE 10. I demoed a couple of the features, including the new API for Build Compatible Extensions in CDI 4.0 lite.

Java Day Istanbul is a community-oriented conference that is supported by the Istanbul Java User Group. It is well organized and features a great lineup of speakers and content. It was my first time speaking in Istanbul, and I surely hope it won’t be the last.

This was my first time speaking at GeeCON. It is a yearly three-day conference in Kraków, Poland, with around 700 participants. This was the 12th edition of the conference. There were three parallel tracks. My talk titled Jakarta EE 10 is Coming YOUR Way, was on the second day of the conference.

Even after 15+ years of performing live demos on stage, it still baffles me when a demo that was not supposed to work, works perfectly fine when run on the big screen… And since GeeCON is in a cinema complex, the screens are really huge.

In the morning before my talk, Otavio and I had a lovely morning run before breakfast along the Vistula river. If you look closely at the picture, you can see the pig floating on the river behind us. Explanations of what it symbolizes differ, just google “Weird Poland” and see if you can figure it out…

That was Jfokus 2022. As usual, an excellent conference hosted by Mattias and his team!

My talk titled Get Ready for Jakarta EE 10 went well. A couple of hours before the talk, I added a brand new demo of the Java SE Bootstrap feature of Jakarta RESTful Web Services 3.1.

I also did the Jakarta EE 8 to Jakarta EE 9.1 migration demo and decided on stage to take it all the way to Jakarta EE 10 instead. Some unexpected hiccups and surprises with the milestone build of GlassFish I was using, but that is sort of expected of a live demo…

Thanks, Mohammed for the picture and tweet of me on stage during the demo!

On Wednesday morning, we had the first annual Jfokus morning run. I brought Jakarta EE shirts to all attendees as you can see from the picture below. Next Jfokus will probably be at the usual time in February, so I guess I will have to bring something a little warmer than t-shirts then…

Umedev is one-day a developer conference for and by the local developer community and IT industry in Umeå. It is completely free for attendees This year’s edition featured three parallel tracks, so there were lots of great content to choose from. Most speakers were local with a couple of exceptions, myself included.

I presented Jakarta EE 10 is Coming Your Way after the lunch break. The presentation contained an overview of what’s coming in Jakarta EE 10 as well as a live demo of converting from older versions to Jakarta EE 9 and above.

It is great to be out talking to developers at these regional events. It is a way of expanding the bubble with influence from developer communities I’m not regularly a part of.
