To pick up my pen An Article by Nick Cave www.theredhandfiles.com The most important undertaking of my day is to simply sit down at my desk and pick up my pen. Without this elementary act I could not call myself a songwriter, because songs come to me in intimations too slight to be perceived, unless I am primed and ready to receive them. They come not with a fanfare, but in whispers, and they come only when I am at work. Touch the keys creativityroutine
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.
