T-SQL Tuesday is a blog party started by Adam Machanic (b/t) just over five years ago. The first Tuesday of each month a blogger hosts the party and suggests a topic. Then anyone who is interested blogs on that topic. It can be a lot of fun and quite a challenge to blog on a topic you didn’t pick.
You’ll want to go full screen to see what’s going on. This video is targeted at non-DBAs, but give it a watch anyway…I can take the heckling!
