Now this is dangerous, for me at least: an attempt to update this site in a totally offline fashion. The steps involved are simple enough in theory, but carry the potential for disaster.
I now have a replica of the live site on my notebook computer, a task complicated by the fact that WordPress, on which this blog is based, uses a MySQL database backend. You can’t simply copy that data over from point to point; instead, you have to export (dump) the data from the database to a text file, and reimport it at the other end. The import is a one-shot process, but before you do that you usually have to delete all the current data from the database.
Or do I? Actually, now I think about it, perhaps I can do something with the single record that will be created when I save this blog entry, by carving it out of the SQL backup. Hmmm…
