The camp Smalltalk will be held prior to the conference: 16th-17th of August starting at 10h in the morning.
The location is here: http://osm.org/go/0EQHdgtv6--?m= 16 mill lane.
It's a little walk from the accommodation, but not much further than the computer lab, and is conveniently sited for restaurants / pubs for when people want to pop out for lunch. This is a bit harder at the computer lab, because it's out of the town centre.
