Hi, Spring fans! Welcome to another rip-roarin’ installmebt of This Month in Spring! It’s been a very busy month since we last spoke, and I’m only getting started! In addition to my all-but-daily schedule for my Youtube channel , and my weekly This Week in Spring blogs, and my usual nonsense on Twitter, and the new free e-book I wrote introducing Spring Boot 3’s AOT engine, and the talks I’ve done online, like this one introducing Spring Boot 3 over on the IntelliJ IDEA Youtube channel that some people seem to like, I’ve also been hitting the conference circuit! I was at Devnexus a couple of weeks ago in Atlanta, GA. Then I turned right back around and flew to Amsterdam, NL, for the fabulous Kotlin Conf 2023, and then took a quick train to Paris, FR, for Devoxx FR 2023. I returned home yesterday, but am back at the airport as I write this, boarded for Chicago, Illinois, where I’ll copresent to the Kotlin and Java User Groups with my friend Justin Reock. Do not miss this, if you’re in the Chicago area, my friends! Then, I’ll come home again and then get right back on a plane destined for Bangalore, India, for the amazing (Great Indian) Developer Summit. I have’t been to that show since before the pandemic, and I’ve so missed it! Once that’s done, I’ll return home for a few days, then get right back on a plane and head to London, UK, for Devoxx UK; to Athens, GR, for Devoxx GR; and finally to Barcelona, SP, for Spring I/O. And all of that will happen, more than likely, before we talk again on this very blog next month! If you’re in any of those places, please come out and say hi!
And as busy as the weeks ahead will be, the last month’s been something to write home about, too! So, without further ado, let’s dive right into it!
