I always test as much as I can before putting on a production server, even if I know the source. Everyone is human even the best, they can all make mistakes. That way if anything goes wrong I blame myself for not testing hard enough, rather than the person who supplied the solution.

There are always times we need to do things quickly. But we must weigh up the risk versus gain in this case, and make it our own call.

I am reminded of the following quote:

Eric Cantona "By all means take advice form other people. But remain true to yourself. "
