Hashtag Jakarta EE #344

Welcome to issue number three hundred and forty-four of Hashtag Jakarta EE! This will be a rather short post since it is in the time of the year most people are on vacation or doing something else than reading blogs. This week, I have attended JCrete with lots of regulars and also made friends among the new faces. I will write a more detailed writeup from JCrete later.

Hashtag Jakarta EE #343

Welcome to issue number three hundred and forty-three of Hashtag Jakarta EE! I have been home a week since JConf Dominicana 2026, and today I am setting course for Crete to be a part of JCrete 2026. This unconference in the Mediterranean in the middle of summer has become a tradition for me since I first attended more than ten years ago.

JConf Dominicana 2026

This was my third time speaking at JConf Dominicana, so I am practically a regular by now. The community spirit is so present at this conference. As I wrote last year, I think it is the only conference I have been to where the attendees immediately put on the conference T-shirt they get at registration. Everybody walking around in matching shirts strengthens the feeling of belonging to the community.

Welcome to issue number three hundred and forty-two of Hashtag Jakarta EE! I am currently at JConf Dominicana 2026. I will post a separate post about the conference shortly. But I will mention the session I am attending right now, which is a presentation about floci by Hector Ventura. In short, floci is a drop-in replacement for LocalStack that lets you emulate any cloud environment locally.

Code the Continuum 2026

Last week, I had the pleasure of being part of the Code the Continuum Hackathon which took place at the University of Gagliari on Sardinia, Italy. The location itself is worth the visit, so I definitely understand the choice of venue. The two-day hackathon was held at the university campus with approximately 50 attendees registered. I had created a challenge where the participants would create a Jakarta EE application that integrated with an LLM to produce an…

Javaforum Malmö May 2026

Last week, I spoke at Javaforum Malmö (Malmö JUG). Since I am the leader of this JUG, I try not to speak there too often, but several circumstances made this time a good time. First of all, our usual venue Foo café recently closed down their business. Their website and email campaigns were our most important channel for announcing events. We also did registration through them, so a totally new setup had to be made.
