Reading through the comments here, I seem to be the outlier on the usage of these idioms. In fact, of the five in this article, I've only ever heard one in actual usage (Rubber Duck Debugging), though, I could say that "Bus factor" has been used, just not that specific term (more "if you were hit by a bus" as a term). The other three, however, I've never heard in my 20+ years in the tech industry (though I do remember the actual Ren & Stimpy episode...).
