never so glad to be forgetful

Remember I said I had a talk to write for this weekend? I'm sitting down to do it at the last minute (as one does) and, upon having a quick look in a folder marked "Talks", have just discovered that I have a talk on this topic that I put together a couple of years ago. YAY.

Mind you, it needs some updating and expansion, but this is going to knock hours off the time required. \o/
