The IT world is full of mantras/revealed truth, passed (often in oral tradition) among developer tribes. Mindlessly repeated from generation to generation, they cause a reckless usage. At best this results in more harm than good, in the worst case: a total disaster worth whole train of money.

How to find out the context?
Can one eat yellow snow?
