When I was working in a team, I did Bug's Anniversaries celebrations. It actually boost moral. February 2th. when I wipe out a production database because the ansible playbooks had hadcorded settings. Since then we use settings repositories and confirmation dialogs when playbooks will run in production. September 2. They day we realise we are unable to restore old backups because of media paths are not related to the data, so when we move all data from different servers with lost all user's images forever. Since then images are prefixed with the db record id where it belongs, later we added metadata to S3 to add extra stuff like user_id, object_id, company_id, etc. so we keep urls clean September 10. Inbox carnaval: we have an small hack that added users to BCC to send newsletter, with the time all users where receiving emails 2 times, then 3, then 4, then 10, then 2 again. It was a threading issue where the variable of the BCC was set to global in certain cases and it appended to the list instead of starting again ... 2 full weeks into that. Python3 and typing was the way to fix it
