Good Morning.
I've been reading Joel Spolsky's (joelonsoftware) articles and they are full of good information and tips. He's a good writer and well worth reading.
I am wondering what other good blogs/articles/books are out there written by similar people - really after leaders/managers/biz owners who are/were developers.
Hope that makes a bit of sense ;-)
Yup, joelonsoftware is a great one, he doesn't write any argumentative essays anymore (the good stuff that makes his blog awesome), but he also runs a stackoverflow podcast (with jeff from coddinghorror [another awesome blog]). Besides those key blogs, I peruse daily...
A must if you're into .NET is Eric Lippert's Fabulous Adventures in Coding. http://blogs.msdn.com/ericlippert/
He's a member of the C# compiler team and answers a lot of questions here, as well. Not only does he give some good nuggets on how and why the C# compiler works the way it does (and therefore some good practices for coding in general), but a whole gang of intelligent people provide interesting discussion in the blog comments.
Besides the ones posted, I really enjoy Steve Yegge's blog. Although he doesn't write very often, it's high quality when he does.
Stackoverflow is always my first choice, not really a blog but very good place to get all types of programming related advice.
