| It’s Getting Hot Out There |

| May 20, 2020 |
Greetings from Phoenix, Arizona, where it’s summertime already. Or at least it feels that way: We have had seven consecutive days above 100°F/38°C. Meanwhile, parts of the northeast United States are still receiving snow. We live in interesting times, that’s for sure.
Speaking of interesting: As we announced last year, Java Magazine is moving away from an old-fashioned monthly publishing schedule to a continuous publishing stream of new articles, quizzes, and other technical material. The first phase encompassed a transition to our new website. Phase two: Starting right now, we are publishing new material on the website twice per month, once at the beginning and again a few weeks later.
From time to time, we will also present a short video; here is the latest. Later this year, Java Magazine videos will include interviews with Java, GraalVM, tools, and related technology experts who will briefly share tips, suggestions, and behind-the-scenes peeks at the internals.
Remember to follow us on Twitter and on Facebook as well. You can send feedback to us via social media or directly to javamag_us@oracle.com.
Take care,
Alan Zeichick
Editor in Chief, Java Magazine
