Darkness Visible

Yesterday I wrote about Knuth's wise words on software patents. In the course of trying to discover when exactly they were written (anyone know?) I found what seems to be the main source for it - a wonderful page entirely about patents and patent madness.

It only goes up to 2003, but nonetheless has lots of unusual links on the subject that are well worth exploring if, like me, you are a sad individual who finds this stuff both important and fascinating.
