Ben Nadel declared June 1, 2008 the first National Regular Expression Day, and to celebrate he hosted a giveaway of regex-related prizes, including Jeffrey Friedl’s Mastering Regular Expressions. As you can see, I won the book and got it in the mail yesterday. I use regular expressions all the time—in PHP, JavaScript, Perl, sed, grep, [...]

May 27, 2008 – 11:35 am
In honor of WordPress’s fifth birthday, I’ve surveyed about 6000 blogs to see how many are running WordPress.
