Oaxaca teachers strike

During the post-debconf6 trip we stayed in Oaxaca and in my flickr images you will have noticed the striking teachers. People that visited the place may be interested in the fact that Indymedia reports that the government removed the sit-in with force.

stupid CL errors

• Do not assume :always does a check on an empty list:

  [1]> (loop :for x :in '() :always (oddp x))
  T

  is the correct result. But deep inside logic involving "have all entries that property?" it can be surprising.
• 0 is not NIL. Stop laughing, it took me 2 days to find that one part of the program thought it was talking T/NIL while the other talked 0/1 or 2. One (declare (type boolean result)) and a few runtime errors later the program gives sane results again.

Pictures sort-of-up

I've uploaded the Debconf6 and Post Debconf6 trip pictures to flickr.

There is still a time-shift problem with almost all the pictures from the trip, I'll have to explore the flickr API to shift the timestamps forward 41 hours. I already corrected my local copies, which I now need to upload to the debconf gallery :-).

Then I'll write a report on the trip on LJ.
