What is 404 - Not Found?
Normally an error given when indicating that the client was able to communicate with the server, but the server either could not find the file that was requested, or was unwilling to fulfil the request for it and did not wish to reveal the reason why.
More recently used to describe a user or individual that, at any given moment will lock up and seem to have no intelligence what-so-ever and will not co-operate to solve an issue. (ie No Intelligence Found)
