I don't want to start a war but I'd say that this list is about the differences between a Windows VS Linux developer. The thing behind what is said is "get your eyes off of the nice UI. Look and type code".
Doesn't use windows.
Uses the tools listed in the article on windows. (well, windows equivalents anyhow)
I think the message was more of "Know your tools, know them well. Know them, and what they are capable of so that you may wield them to their fullest potential". For software, this involves reading the source when it's available.
