A perl script that you cannot execute:

dennis@lightning:/tmp$ echo -e '#!/bin/rm\nHello World!' > rm.pl
dennis@lightning:/tmp$ perl rm.pl
dennis@lightning:/tmp$ ls rm.pl
ls: cannot access rm.pl: No such file or directory

What happened there? Perl is using too much black magic when parsing shbang lines, including this little nugget: http://perl5.git.perl.org/perl.git/blob/HEAD:/toke.c#l5034

Oh the fun that can be had with this :)

So, there was water in the freezer's circuitboard casing. That explains the earth leakage detector tripping five times in the last days. Cleaned up, defrosted the freezer while we were at it and the food is now re-freezing.

Now to put the freezer back were it belongs, which screw went where again?

Got a new gadget: a garmin gps watch for running. Todays track is at http://connect.garmin.com/activity/116289976

Time to re-run and re-skate all the good tracks.

Python oneliner of the day, adding linenumbers to text: print "\n".join(["%s\t%s" % x for x in enumerate(text.split("\n"))])
