How do you know when your paintings are finished? A Quote by Gerhard Richter matthiasott.com When nothing disturbs me and I have no idea what to do more, what I could add or destroy. This is very surprising, often, when I’m painting, again and again, every day and it feels like it is never-ending […] and it will never become a good painting. And suddenly, it’s finished. Oh! Good. Thanks. Painting With the Web perfectionprogressending
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.
