CloudSec manager at that online-bookstore-slash-server-rental company, adjunct professor at RIT, former janitor for r/cybersecurity, and sporadic FOSS contributor. Cat person. Generally cheerful ^_^

Always trying to learn new things, and I'd rather be corrected than be correct. I try to be correct the first time anyway though!

How can I help?
