some marginal hack collections   (link)

http://www.jwz.org/hacks/marginal.html
So, here's some stuff. I wrote these programs because, at some point, I needed them. That means they are not necessarily very pretty, but maybe you'll find some of them useful. A lot of this is not the greatest code in the world (in particular, most of the Perl programs below were written a long time ago, when I was just learning Perl -- or rather, when I was still trying to use Perl only as a last resort.) So take most them in the context of ``one-hour hacks that have lived on far longer than expected.''
