Command line wizards are forever encouraging the rest of us to learn regular expressions (regex). We're told regex is elegant, powerful and incredibly useful.

The downside is that regex can be seriously fiddly. One fly-spot out of place, and the code fails. For this reason I only use 'non-simple' regex when I absolutely have to. But when I do, sigh... Regex really is elegant and powerful, as the following example shows.

The Mozilla Foundation today is filing a petition asking the Federal Communications Commission to declare that ISPs are common carriers, but there's a twist.

The FCC doesn't have to reclassify the Internet access ISPs offer consumers as a telecommunications service subject to common carrier regulations under Title II of the Communications Act, Mozilla says. Instead, the FCC should target the service ISPs offer to edge providers like Netflix and Dropbox, who need to send their bits over ISP networks to reach their customers. Classifying the ISP/edge provider relationship as a common carrier service will be a little cleaner since the FCC wouldn't have to undo several decade-old orders that classified broadband as an "information" service rather than telecommunications, Mozilla argues.
