A Strong Cup of Java

/ jstevenperry / Leave a comment

Hey everyone!

If you’re interested in the goings-on of the Java language, be sure to check out my new Web Series on IBM Developer called A Strong Cup of Java.

The show will focus on interesting topics in the world of Java.

Episode One is about Jakarta EE, where I talk about what Jakarta EE is, and how it got its name (whatever happened to J2EE?).

Episode Two covers the launch of Jakarta EE 8 (the first release of enterprise Java since Java EE 8 in 2017) that happened on September 10, 2019 in an all-day live stream called JakartaOne.

In the coming weeks, there will be eight more episodes published (I have a 10 episode committment from IBM for the series). With your support there may be more, so please watch!

Click here for the show notes page at IBM Developer.

If you have ideas for topics, please let me know. Thanks for reading!
