I often wish there was a date attached to the articles there. I get that a wiki format is ever evolving and as a result there isn’t necessarily a meaningful date that could be added. However, unlike an article about Jupiter, carbon fiber or WW2 on Wikipedia, the date for when a guide was written about Power Management on Linux is very relevant. I often find myself trying to sort of deduce that from the history page, then I fail then I have to go look up if that information is in fact the most recent.
