StableBlog

This is a repository containing TeX vesions of articles in my blog. My hope is that links to this repo will have more longevity than links to Blogger.

I'm actively in the process of creating this repo and these are preliminary draughts for now.

I've made light edits, mainly to eliminate overfull hboxes and to make sure code compiles with GHC. I've left in material that may seem a little dated now.

Note that when you view a PDF directly from GitHub it appears not to have the external links in it. So download it if possible.
