Mark J. Dominus is a Perl god. But it turns out he has other interests too, and, more importantly, writes well about them. Read his blog, syndicated here on LJ as markdominus. For a sample, try this entry, on philosophical languages, Biblical approximations of pi (check out entry linked within, too, featuring our own khatul), 17th century clever bishops trained in science (an extinct species nowadays?), and serendipity.

Hat tip to gaal who alerted me to MJD's blog.
