Hi Spring fans! Welcome to another installment of _This Week in Spring_! As I write this, I'm on PTO in beautiful Santorini, Greece, catching up on some news and about to cruise the islands for some sightseeing. There's nothing quite like springtime in the Mediterranean! I couldn't dream of enjoying the weather during the spring season until I checked in on which way the wind was blowing in the Spring community, and so here we are! Let's dive right into it!

In last week's installment of _A Bootiful Podcast_, I talked to _both_Dr. Venkat Subramaniam _and_ James Ward, ahead of a talk that the three of us gave at Voxxed Days Amsterdam called _Intelligent Kotlin_.
