That was a good day. Through to Edinburgh to pick up a copy of @cstross latest 'The Regicide Report' from Transreal Fiction, pint in Greyfriars Bobby's Bar (full of tourists, to no-ones surprise) and a tour around the Edinburgh Hacklab.
Now devoured said book. Makes a suitably semi-apocalyptic ending to the Laundry Files. And I need to go and read up on Operation BARMAID, which is a bit of Cold War insanity I hadn't heard of...
