This Week in Spring: Kubernetes, Kotlin, KNative, and More

Hi, Spring fans! Welcome to another installment of This Week in Spring! I flew 14 hours to Tel Aviv, Israel. I then spent 28 hours on the ground visiting customers, visiting my friends at Codota, and then presenting to a packed house at the Israel Java User Group. Then, I flew another 14 hours back to San Francisco, CA, where I presented for a four-hour online course on using Kotlin with Spring Boot. Tonight, I’ll fly to Atlanta, GA, for the incredible DevNexus conference where I’ll be presenting (twice) with the good Dr. Venkat Subramaniam on Kotlin (and Spring) and more. And then, I’m doing a four-hour course on testing. Join me!
