It ' s more like this for me , tbh . <| sep |> I ' m interested in what you mean by crushing or following energy . This sounds like it could be analogous to the 12 Bridge Hands of Hung Gar . The Bridge Hands describe and quantify interactions with the opponent ' s upper body . They could be described as energy , and include tags such as Pressing , Sinking , Pulling , Lifting , etc . Do crushing and following describe a type of action , rather than a specific action ? For example , Pressing Bridge describes any interaction where your forearm is on top of your opponent and pressing downward . <| sep |> I completely agree with you , about the BSD filesystem hierarchy . As a sysadmin , I absolutely love how with the BSDs , the distinctions between bin , usrbin , and usrlocalbin are made very clear bin is for binaries required for booting the system usrbin is for binaries that are not required when booting the system , but are shipped with the operating system usrlocalbin for everything else locallyinstalled packages . The hier 7 man page in Linux , is too generic and IMO leads to a hot mess . In an ideal world , I would like to manage a fleet of BSD systems , but more often than not , a lot of the people I work with like to leverage facilities that only really exist in and for Linux e . g . Docker .
