Ask HN: What's the best way to learn about project management?

I've just started a new job, which involves a lot of project management. This is something new to me, but I understand enough to know there's a lot more to managing a project than software (and to know this doesn't really come naturally to me).

Where can I learn about the true art and science of good project management? I'm looking for both practical tips, and also details about learning the processes used by major public and private institutions.
