Welcome to another installment of This Week in Spring! It’s already June! Where. Does. The. Time. GO?? This week I’m in Chicago, IL, for the Chicago Coder Conference, Boston and New Hampshire for customer visits, London, England for Devoxx UK and Talin, Estonia for Geekout EE. If you’re around, be sure to say hi! Now then, we’ve got a lot to cover this week so let’s get to it!
