I really don't want to rile anyone's feathers and I really enjoy blogs like Joel, Coding Horror, Scott Hanselman, etc.
However, what are some good blogs/podcasts that focus on other platforms besides Microsoft based ones or maybe even no particular platform at? In particular I am interested in areas like Python, Ruby, Java, C, but any area besides Microsoft fits the bill.
There may be other similar questions to this but I think this one is unique since we might get some answers we wouldn't see otherwise, that is, everyone knows Coding Horror is great.
Please try to refrain from religious debates; the content of the blog is more important than the platform they are talking about, I just want to get an idea of what is out there and worth the time.
