Hi, Spring fans! Welcome to another installment of This Week in Spring. By mistake, I inadvertently published older content in this installment, then tried to fix it and ended up re-publishing the same content. And, what's worse, I somehow ended up deleting the draft I had written for this installment — the one I intended to copy in to override the bad content. Ugh. A comedy of errors. Anyway, this is a lesson in why you should make sure you get enough sleep. And this is why I am now re-writing the same content again!
