Done yesterday (20091208 Tu)
2009-12-09 09:37 amA good day. I continued to be cheerful -- it's been a week now that my mood has been noticably above neutral. I'm told I should simply enjoy it and not worry about the reasons; I suppose the Centipede's Dilemma is a good reason for that.
I took a walk that was considerably shorter than usual, but also faster: fast enough for what I think was a decent cardio workout. I had to slow down toward the end, because I was definitely feeling it in the legs. The book Fitting In Fitness, which I finished a couple of days ago, suggests taking one's exercise in three 10-minute chunks instead of a solid half-hour. Hmm.
My weight was down, too, for the first time in over a week. Probably either the increased exercise, or the lighter-than-usual lunch (prunes and beef jerky). I'm not complaining.
(9:45) Almost forgot -- I got up and tried to distract a crying baby in the Kaiser waiting room while her mother was signing in. I was only partly successful, but had a nice little conversation with the mother. Fun!
Two insights. The first was that what I've spent on family members' air travel this month has been less than I'd been paying on my Honda (which I finally paid off a few months ago). The second, much geekier but more amusing, is that you can fit three SHA-1 hashes and some type information into a Twitter post with room to spare. So you can implement LISP.
(defun cons (a d)
(let (c (concat "(" a "." d ")"))
(post twitter (concat c "=" (sha1 c)))
(concat "cons." (sha1 c))))
The definitions of intern, equal, and
eval are left as an exercise for the reader.
