Not dead yet

The last ten days have included a fascinating conference (which I really should have plugged a few more times; more on that anon, probably), the arrival of some old friends in Edinburgh and a bout of unwelcome illness that have together conspired to keep me offline. The previous two posts were scheduled to go up ahead of time and I am only just back on very briefly today. It may be another day or two before I get a chance to post anything as I try to catch up.
