Done yesterday (20091208 Tu)

1208 Tu
  * up 7:00; W=198.4; drugs, nose, teeth
    ! pleased about the weight loss
  : Cold.  heavy frost on the car.
  $ aha: realized that my air travel probably averages out to roughly what I
    was making in payments on the Honda
  & Distracted a crying baby in the waiting room.
    ! happy.  That was fun.  Thought of N a little.  Other person waiting
      thanked me profusely.
  ! feeling pretty cheerful right now.
  * walk: ~15 min. but very brisk
    | definitely feeling it, and had to slow down at the end, but it was
      almost certainly a cardio workout.  If I can do a couple of those every
      day, FiF style, I'll be doing well.

  : aha: (type.[sha1]-type.[sha1])=[sha1-of-cons] fits in a twitter line
    93 bytes for the CONS and another 41 for the =[sha1] = 134

  * 6pm Avoid Avoiding
  * Called C; went to voice mail.  As expected, but I still wish I could do
    sometyhing to cheer her up.
  % Chaos apparently told Colleen that she misses my singing and guitar
    ! pleased but quite surprised.
  * bed ~11pm

A 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.
