Has MySQL/MariaDB server ever run away from you? If it hasn’t, you’re lucky or you’re likely to use PostgreSQL instead. Today I’m trying to restore a database from backup (database dump) onto a new MariaDB server. This is what happened: The database size is 1.7G, and this should not surprised a database administrator.

Though there is no built-in function to allow changing font size on the fly, urxvt allows us to do this via extensions....
