• Tom Coates observes that daypop and blogdex have been overwhelmed by political posts from the U.S. and calls for balkanizing them, so that there is some opportunity for other ideas to be heard and found. There's a role here for topics and categories. People have been talking about topical weblogs but I'm not sure I'm ready to go that far.

Reading Dan's post rang a bell in my head regarding CPS and Static Single Assignment (SSA) form. When I left graduate school. SSA was becoming the IR of choice for compiler optimizations. Richard Kelsey wrote a paper regarding A Correspondence between Continuation-Passing Style and Static Single Assignment, which showed how to convert programs in CPS form to SSA form and the reverse. There are few CPS programs that cannot be converted to SSA, but they are not generated by the usual Lisp/Functional language to CPS conversion algorithm.
