The problem with trees Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as: HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS only to find a reference to another leaf: Please see HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.

If I had The Sads Back before COVID-19 hit the global scene, I thought it would be pleasant to have a list of the good things in life. This list wouldn’t be an exhaustive account of all the checked boxes on Maslow’s Hierarchy of Needs, but rather would document small pleasures which evoke some kind of clear and specific emotional response. If I had The Sads, I could pull up this list and sink down into the sensory details of, say, that strong hit of pine scent you randomly get on a hiking trail. Now that we’re all in the thick of this pandemic, this new tiny side project—Good Things—has offered me a peaceful little portal to things I miss. Your mileage may vary, but I’ve found that reading my personal list of good things can be comforting as I help protect my community by sheltering in place.
