I feel absolutely horrible this morning. Partly physically grotty (one pint of Fuggled Frog too many last night I suspect, and also I'm still suspicious that my hayfever season might be getting under way); partly mentally groggy (it's been a mildly weird couple of days and my brain has taken a bit of a beating); and partly everything just seems to be at one remove from the inside of my head, and it keeps slightly surprising me every time my muscles actually do things I tell them to like turning my head to look out of the window. (Though oddly it doesn't feel strange that I can still type; I think my typing reflexes must have evolved a much closer connection to my brain in the years I've been a geek…)

I want not to be at work today (but I'm by no means ill enough to justify actually going home). And I want to go back to bed (but even if I did I wouldn't actually be able to sleep). And most of all I want the biggest hug in the universe.

Hmm, well, that feels a bit better. Went into town to do chores and get a haircut, and while I was there I cheered myself up by indulging in some therapeutic DVD-buying, running into Kit and Oliver the former of whom provided a much needed hug, and grabbing a snack Chinese meal from the very wonderful Bridges Patisserie. Now feeling a whole lot more cheerful and also better fed. Yum.

My ex-boss just wandered over to brag about a neat piece of machine code hackery he'd just worked out (specifically, single ARM instructions that set the N, Z and C flags to any meaningful combination of values).

I promptly flicked over to my editor window, and opened up a text file I wrote within a month of arriving at ARM (i.e. four and a half years ago) containing exactly the same analysis. Then I showed him the timestamp. He was a bit put out >:->

(Somewhat spookily given there are many equivalent instructions for most possibilities, we turned out to have produced exactly the same table. Evidently I absorbed the ARM groupthink excessively fast…)
