In which Ian Carroll casually compromises a Turkish root CA trusted by most browsers: https://ian.sh/etugra
Security concerns with the e-Tugra certificate authority

Certificate authorities (CAs) are a critical backbone of internet security; when they are compromised, users lose the ability to securely connect to websites without fear of interception. Websites cannot insulate themselves against a fully-compromised CA, even if they normally use other CAs.

I wanted to add a rand() biased default value to a column in #MySQL. To support replication, that is not allowed, so you must use a trigger. You cannot use the trigger to update the inflight INSERTed rows unless you set the trigger to occur BEFORE insert:

Example:
DELIMITER $$
CREATE trigger set_rand BEFORE INSERT on `tbl` FOR EACH ROW
BEGIN
IF NEW.randcol IS NULL THEN set NEW.randcol = FLOOR(RAND()*999999999);
END IF;
END$$
