Rule no. 1. Never trust strangers on the Internet. They are out to take your wallet and turn your brains into green mush.

If you're still reading after this, rule no. 2: look for primary sources written in tech manuals, scholarly articles, full-length boring books replete with references. Eff Wikipedia, it's full of it most of the time (except for reference sections which can guide you to some of the primary sources).

Rule no.3: collate, collate, collate. Everybody lies by commission or omission, understand their motivation and make sure you have several independent sources with diverse motives to compare with each other.
