Hi I'm cts aka gf_256. This is a list of most things I've worked on.
I'm too lazy to setup and host a blog myself, so things I make usually end up (1) on the company blog; (2) in a Github gist; (3) in a Github repo; or (4) in someone else's publication. A lot of the things I write are too small to deserve a spot on the homepage, but I still want them to be discoverable by search engines so they can help other people.
