Oftentimes you want to make sure your site isn't being IFRAME'd. Sometimes it's for security reasons, other times it's so your site's content isn't being skimmed else, and other times it's...oh, who cares, you just want to do it. Here's a short way to escape frames:

I get asked loads of questions every day but I'm always surprised that they're rarely questions about code or even tech -- many of the questions I get are more about non-dev stuff like what my office is like, what software I use, and oftentimes...
