I have a log_format in nginx which uses the $remote_addr variable. It has a variable width — it can for instance be 76.4.56.100. For alignment reason in the logs, I’d like these addresses to be all logged in a normalized, fixed-width format (here, 076.004.056.100). Can it be done? I tried and failed at: using map […]
I have MySQL 8 with the mysqlx plugin enabled running on a standalone server that will never allow access to 3306 from outside the instance and have no worries about security within the instance.

How do I find out who to tell? Never mind. Writing the question here helped me find a different way to ask it, which probably should have been obvious to me but wasn’t. Google “[organization] security exposure reporting” There may a way to contact them privately, for example via private mailing list.
I’m trying to create an online quiz app, so I was wondering how I could check answers. The first thing that I could think of is to submit all answers to the server, and that get form server witch ones are correct and which aren’t. But my goal is that I can have real-time quizzes […]
