What programming related blogs do you visit regularly?

At least once or twice a week I go and visit some blogs that have at one point or another helped me out with a problem or had a couple of good programming related posts that I have enjoyed.

However many of them post infrequently now so I'm curios if I might be missing out on some great frequently updated tech blogs in 2012.

This is a part of my list: http://www.facebook.com/Engineering http://blog.heroku.com http://engineering.twitter.com http://blog.reddit.com http://code.flickr.com http://wanderr.com/jay/ http://blog.ksplice.com http://cr.yp.to

Anyone willing to share theirs?
