It's come to my attention that some people have been spamming issue trackers with a link to this gist. While it's a good idea to inform people of the situation in principle, please do not do this.

To fix it (with MariaDB still running):
sudo mysql then enter your Mac user passwordALTER USER 'root'@'localhost' IDENTIFIED BY 'newrootpassword'; replacing newrootpassword with the password you wish to use for the MariaDB root user.You should then be able to connect to MariaDB with mysql -u root -p, then entering the root password when prompted.

Only one person showed up to discuss the topic: Patrick Debois. Their discussions and sharing of ideas with others advanced the concept of "agile systems administration". Debois and Shafer formed an Agile Systems Administrator group on Google, with limited success. Patrick Debois did a presentation called "Infrastructure and Operations" addressing
