Come to the Hartford Ruby Brigade’s January Meeting

As we trudge back to our regular schedules after assorted holiday debaucheries, here’s a heartening thought: Hartford.rb is meeting on Monday, 1/26! Gary Wright will tell us the story of how he learned Git, and some lucky stiff will walk away with a free copy of The Rails Way. We’ll even have pizza — though we’re now on the look-out for a pizza sponsor, so if you know anyone looking to feed us (for only ~$50 a month!), it might even be free.

The usual details:
Monday, 1/26, 6 – 8 PM
GeeZeo
750 Main St, Hartford

See you soon.

Accuracy and Precision: Not the Same

I often hear people mis-use the words accuracy and precision, but they mean different things.

To say I’m 117 years, 93 days, 4 hours, 17 minutes, and 48.249 seconds old is very precise, but it’s inaccurate (right now, anyway).  To say I’m in my thirties is accurate, but imprecise.  Precision is about level of detail, accuracy is about truthiness.

They make a wonderful pair, working pretty much orthogonally to each other.

Wikipedia has a nice analogy using a bulls-eye target.
