The nature of blogging is such that, if you don't start it when you start doing the stuff you eventually decide you want to blog about, things get out of sequence and dates start to bear little relation to when you did stuff.
Relationships between posts break down unless they are blogged as and when things happen.
That will be the nature of, hopefully only the earliest posts, in this blog.
In particular it is now two years since I first started mucking about with a Raspberry Pi, and I have done a mass of stuff since the end of 2012, when my first Pi hit my doormat.
Hopefully that won't matter too much, but where it does I will try to fix things with comments about time-line issues in the text.
