My blog has languished for a few years. There are a number of reasons: time pressure, laziness and a few problems with Pelican. I have decided to use Nikola and my static site generator. I have converted the text in all the old posts to work with Nikola. However, there is a lot of work to update all the embedded photos. At the moment a lot of posts have embedded html which is incompatible with Nikola, so raw html and not photos are displayed! I am steadily working my through old posts fixing this.
