Open Source - A Journey of Contribution and Collaboration

Have you ever worked on a project that didn't use any open source tools, libraries, or products? Didn't think so...Using open source has been such an integral part of our daily work life that we don't even think about it. We just expect it to be available, secure, stable, and bug-free. But how many of you are actually contributing back to an open source project?

This session will go through a couple of the aspects to consider when you are embarking on your open source journey. We will look at different kinds of open source projects, and what the open source foundations bring to the table.

Jakarta EE 11 - Performance and Developer Productivity

Jakarta EE 11 will be the first release of Jakarta EE after the new release cadence was introduced.
The goal is to release a version of Jakarta EE around six to nine months after an LTS release of Java SE.
With Java 21 released in September 2023, Jakarta EE 11 is scheduled to be released around June/July of 2024.

What are the updates? Are there any new specifications introduced? What about removals? Will there be another namespace change? How will the impact of this release be on other frameworks and technologies, such as Spring, Apache Tomcat, Hibernate, and more?

Come to this session to get all these questions and more answered to be prepared for Jakarta EE 11.
