We're probably doing something else nerdy, just for the fun of it.
Like brewing a beer to bring to our team's beach retreat and naming it API IPA. (We wanted to call it Hacker Shore but <cough> somebody objected.) Preliminary human factors studies indicate that consumption of API IPA does not actually improve coding ability (p=0.05), but hey, maybe we just need a larger sample size?
So if you picked up our coaster at a conference, we hope you put your favorite beverage on top and do whatever it is that you do to unwind.
