Off-heap in-memory database, changes to certification exams, and the history of DevOps
Week of December 14, 2020
The Alice Project is inspirational. Created more than two decades ago, the project from Carnegie Mellon University uses a Java-based programming environment to teach software development. “Alice is designed to teach logical and computational thinking skills, fundamental principles of programming and to be a first exposure to object-oriented programming,” the project’s website says.
In late November, I chatted with Eric Brown, the project’s director; you can watch the video here.
I also spent quality Zoom time with Daniel Abeshouse, Alice’s lead developer. Eric, Daniel, and I are working on a deep-dive technical article to be published early next year. Stay tuned.
There’s lots of new stuff for you at Java Magazine; read on for more details.
One final note: Imagine a virtual developer event taught only by Java Champions. And there’s no charge to attend. Register for the first-ever jChampions Conference, coming January 13–19. See you there (virtually, of course).
Take care,

Creating a Java off-heap in-memory database Eric Bruno explains how if your Java heap size is constrained to be very small (say, 16 MB), you can create an in-memory, off-heap data store that holds gigabytes of data—or even more.
How Dev versus Ops became DevOps We revisit Stephen Chin’s 2015 interview with Patrick Debois, founder of DevOpsDays, which explains how the DevOps movement started and where it’s headed.
Andrew Binstock lauds the author’s deep understanding of JVM internals, which is doubtlessly rooted in his work at Oracle with the Java team (and in similar work earlier at Sun Microsystems).
