Welcome to another installation of This Week in Spring! As usual, we've got a lot to cover so let's get to it! This week I'm supposed to be in Paris and Belgium. Unfortunately, because of the recent, tragic, disgusting and cowardly attacks on the Brussels airport and metro, I am not entirely sure about whether I'll be in Belgium physically. Tonight's meetup talk, however, will carry on remotely, via streaming. Stay tuned to my Twitter handle - @starbuxman for more.

That said, there's a lot of great content so let's get to it!
