This meetup will be at 7:00 PM on Thursday May 8 in Talbert Hall  107 on

little to the left of the Flint Loop. You will probably park in either 
the Fronczak or Hochstetter lot. No permit is required for parking in 
student lots at this time of day.

Our speaker, Bill Chapman is a Software and Operations Engineer who 
specializes in helping businesses make pragmatic decisions about the 
technology they use and the software they create.  He is currently an 
operations engineer at cloud computing solutions provider Stark & Wayne 
and a partner at software consultancy Division By Zero.

We've been settling for light refreshments and will do the same. 
*doolli* is our current sponsor.
