append newline at end of files

Frequently when you download source code off the internet and try to compile, you end up getting a bunch of "warning: no newline at end of file" . to append a newline at the end of each *.c and *.h files use the following one liner.

find ./ \( -name "*.h" -o -name "*.cpp" \) -exec perl -i.bak -lpe 'print "\n" if eof' {} \;

ps: the space between the '{}' and '\;' at the end is required and there is no space in between "\;". else the follwing error occurs

find: missing argument to `-exec'

Sunglass

While this place has mostly computer related stuff, this time I just want to say if you are running a marathon and it is expected to be sunny, a sunglass helps a LOT. Not that I am a great runner or anything. But this time I was wearing one and in between at around 34 km or so, I took them off and boy the sun looked horrible and I can easily imagine it would be far more depressing without the sunglass. FWIW I shaved 1 hr and few minutes off my last years 7 hrs 15 mins time and I am sure the sunglass made some difference.
