Just a place to put
some links and notes collected in my inbox since the last one on the 13th
December 2014… Wow, it is over a third of a year since I last did one of these.
In a break from tradition (and start a new tradition), I’ll put the latest
received stuff at the top and work down backwards in time.
PS Apologies if I’ve
failed to reply to any emails/comments this year, it’s been a hectic 2015 so far...
