The old blog was running on a self-hosted ec2 instance for at least ~11 years, becoming increasingly difficult to upgrade and manage. I've finally pulled the trigger and rebuilt the site here. This should make posting, commenting, and formatting easier.
The new blog host allows for email signups - so if you'd like to receive an email when I post, please join the mailing list. I only post a few times per year, so it won't overwhelm your inbox.
