What is a coder's worst nightmare? (2014)
Other coders' nightmares:<p>* Security : customers acccounts leaked, identities stolen, bank account depleted<p>* Undetected data corruption : customers' data is corrupted and it has seeped into the backup stream, even the off-site one, and that is corrupted as well now.<p>* Rarely occurring simingly random concurrency related bugs that manifest themselves once a month or longer.<p>* Time : making assumptions about it, dealing with it distributed systems etc. Nobody thinks about it until it stops working or systems' time gets snapped back somehow.
