With the blog available, the "Articles" section of the site seems a bit redundant. I’m going to copy/rewrite the articles posted there into blog posts and redirect links to these posts. Eventually, the Articles section will be going away.
This means you will probably see some topics come up here that seem familiar. Some will be extensively rewritten as known facts have changed or my understanding of the facts have changed. Others will be largely untouched.
