Dinosaur While checking my logs for this site and seeing the usual malicious requests against every spammers favorite software WordPress I decided to make things a little harder for them with a tarpit. more

A while ago I published a snippet to generate an OTP auth token from the command line, but I recently got a new phone and had to re-add all my secret keys to a different authenticator app. As I keep all the secret keys backed up I made another script … more

Wagtail has "scheduled" pages that are not yet visible on the site. I think the interface is not ideal as you need to click the Publish button after setting a publication date on the Settings tab. I'm not sure how exactly the data models work, but the actual publication is … more

I recently added OTP authentication using pam_google_authenticator.so to most of my machines.
