Mostly about effectivity vs. efficiency in terms of game programming.
lyndibeige's Youtube channel
I found a quite interesting channel on Youtube including many good explanations and reasons for why most fantasy/mythology movies thingies are simply wrong. Why battle axes are so small, why hoplit are unlikely do do certain things they are somethings pictured doing and so on. Most interesting videos are older and you better skip the newer ones, stop the autoplaying video at the front page and avoid everything including stupid video stuff not beginning with "some point(s) about" or so. Following these rules, it's a very interesting output.
