3579 - Transport in Cambridgeshire - seen by an outside observer. What can Wiltshire learn?
A week in Cambridge - traveling there, and around when I needed, without a car - and a chance to look, listen and learn a bit more about the wider transport issues of that city.

3572 - Adding Expect on top of Tcl - what is it and where can I get a training course to learn about it?
