Hi, Spring fans! Welcome back to another installment of This Week in Spring. It’s a big week ahead: I’m about to head out on a packed tour through Europe—Wrocław for a friend’s wedding, Oslo for JavaZone, Paris for a Spring meetup (details coming soon), Amsterdam for IntelliJ IDEA conf—and then on to Kansas City for KCDC. Busy? Absolutely. Fun? Even more so.

And since I’ll be spending plenty of time in the air, I’ve got plenty of reading to catch up on. Here are some of the standout resources from this week’s roundup.
