Link roundup 2008-01-21

I've got so many little notes that don't warrant a full-blown story, so here's a link roundup:

• Perlcast interviews Curtis Poe about logic programming and Prolog. Is Fluffy a mammal?
• Adam Kennedy provides a mathematical proof that Perl is unparseable.
• chromatic is tracking down memory leaks in Parrot (but if you follow rakudo.org, you already know that).
• David Landgren has posted another of his marvelous Perl 5 Porters weekly mailing list summaries. If you want to know what's happening in Perl 5.10 (and 5.12) development, but can't handle the volume and/or high-level discussion, David's summaries are the place to go.
• Andy Armstrong has performed magic to let you instrument your Perl code with dtrace.

There, that feels much better now!
