My Blog: Blue Sky On Mars

I've been blogging at Blue Sky On Mars for 15 years. I don't blog consistently, though. Recently, I've started writing at articles.blueskyonmars.com, which is a Medium site with all of the good things that come with that. I'll also sometimes post non-software writing at my personal Medium page.
