Hi, Spring fans! Welcome to another installment of This Month in Spring! And what a month it's been! Usually, when I publish these roundups, I delight in being able to take stock of my life and recount the places I've been, people I've seen, and the things I've done. This month, however, is, of course, a little different. My family and I have spent another month - our second - sheltering at home, trying to avoid the COVID19 pandemic, as I'm sure a good deal many of you have been, too.
It has been equal measures exhausting, scary, and relaxing. I don't know if you need to hear this, my friends, but it is OK to find this situation terrifying, to feel anxiety. It's natural to feel dispirited. It has helped my family and me to remember that we're not alone - that others are going through the same situation - and that if we keep calm and carry on, as they say, we will get through this. My family and I have used this opportunity to rekindle friendships, to check in on elders in our respective families, and to - through our shared distance - forge stronger connections with people.
I've also been trying to use this time to learn new things. I love learning.; it's calming, and it's worked for me. What about you? Have you learned something exciting? Rekindled connections lost? How're you doing? I'd love to hear from you, as always. Sound off on Twitter (@starbuxman).
Now then, we've got a ton of stuff to get into today, so let's!

- On a personal note, I am honored to have in the last week have been made a Google Developer Expert for Kotlin. It's a recognition of my contributions to the Kotlin community. I am humbled by the recognition. Thank you, community, for loving Kotlin as much as I do. I am already a Java Champion, and now a Google Developer Expert for Kotlin. If it was not obvious, I love the JVM ecosystem. I am one of the few Google GDE's for Kotlin on the server-side, and that's entirely because of the vibrant and wonderful community surrounding Spring and their use of Kotlin.
