Are you a web developer who works with Ruby on Rails, MySQL, Apache, Linux, jQuery and so forth? What (professional) blogs and news sites do you read? I do web development in Rails for a small startup. For a long time, I've more or less worked in a vacuum, but I'd like to change that.

I have a long list of trashy blogs and news sites I frequent. I'd like to replace them with healthier choices -- things that will help expose me to new but relevant technologies, or just neat tricks with the technologies I already know. What sites do you recommend?

I am already fairly familiar with local user groups, mailing lists, and print media. I'm specifically interested in blogs and news sites that I could add to my web-surfing rotation.
