My most memorable "small victory", in terms of maximum enjoyment:effort ratio, is this one.

I've had plenty of others, though. A thirty-line script to search through a filesystem and convert documents from an obsolete format to a new one (the conversion script was already written, and is probably not one of my finest works, but it does work), for instance.

It seems like most of my projects lately are in the 200 to 300-line range; nice manageable one-person work, and the sort of "easy job" that Perl makes enjoyable. I suppose that is a significant "small victory".
