We are here with a carefully curated reading list! We put together the best content from the world of Java, Jakarta EE, cloud computing and open source. 

TL:DR - if you work with enterprise Java software, you'll find something here for you. 

This month, we've seen a lot of great, high performing learning materials about how to get the most out of your tools. There is new 'How-To' material on how to maximise your use of two of the most popular IDEs we see Jakarta EE users and Payara Platform users opt for: Donald Raab and Sebastian Daschner on IntelliJ IDEA, and an Eclipse IDE for Java shortcuts video. See below to listen to Don and 'Level Up your IDE!' Our social media followers also loved the guide to Gradle shared below. 

And, after January's announcement of Java SE licensing changes, and thecrackdown on non-compliance, our Community has been getting to grips with what this means - and the other options out there. As Java was open sourced back in 2011, you've got options other than the Oracle commercialJava SElicense. We have a guide that goes through your OpenJDK options, check it out:No Nonsense Guide to JVM Implementations: OpenJDK, OpenJ9, GraalVM.

Though we try to keep these roundups all about celebrating others, we've got a lot to be proud of this month as a company - launching our firstHackathon(entries are closed now, but stay tuned for the results!), and rejoiningMicroProfile Working Group! 

We hope you enjoy the wealth of great resources created by our community, even in this shortest month of the year.
