I’ve read a few interesting articles by this guy, so I should mention him here. Erik Sink is a developer at SourceGear. He has great insight into the subject of his work, and has good views of the industry in general.
His blog is definitely worth the read.
Articles to note:
Source Control HOWTO - a great series on how source control works. Great for those new to the subject.
Be Careful where you Build - How do you decide what Platform you write your program for? This is a good discussion.
