So, instead of sitting in front of the computer and working on the presentation, I printed out the paper (such as it is) and began working on slides as boxes on pieces of paper around key phrases. It's messy, but that's part of the point. I got the bulk of the paper (up to the section describing the rationalised rule which defines the idea of a descriptor) rendered as about 18 slides. I'll have to trim that somewhat, but it's about right timing-wise.

Did some exercises for 10 minutes or so, just enough to convince me that I need to be doing a heck of a lot more. Starting to get soft and creaky.

Oh, didn't mention this yesterday, but I did finally get CD burning and DVD playing working. Was just a matter of changing the permissions. Once that was done everything worked as expected.

For now, I think I'll call it a night, turn on Harry Potter (PVR'd from the CBC this evening) and give my hands a rest.
