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.

Death at Home An Essay from Every So Often a Talking Dog Appears by Smiljan Radić To build a follySimple moments of clarity
To build a folly To build a folly is essentially to do something a second time, something at an inopportune moment. That something is always the memory of something forgotten, about which we can paradoxically say "There it is again." Follies were misunderstood, purposeless constructions. They were often only small, extravagant gestures in a garden, easily whisking off the imagination to distant lands, a sort of time capsule built to awaken the memory and induce surprise in passers-by. They marked locations, organized secondary paths in a park, or simply predicted the arrival of better times—a demarcation, a sacred spot, a mysterious trail, a hill whose tragic rocky nature begged for a tower, a party, or the arrival of summer.

Simple moments of clarity I have seen autistic children drawing at a terrific speed and I've always thought that my drawings should not be less rapid, because that speed gives them insignificance. In this speed lies their abandonment and it may cause them to be overlooked as mere doodles. However, I understand that they are like that pristine light that appears when they tell you that you have a tumour. In an instant, everything becomes clear and well-defined. All contours are cruelly illuminated as if it was worth taking a final look at the world. At such times, although the lines in the drawings clump into a skein of events that are indecipherable to ordinary mortals, they can be described in detail by the victim one by one. These are moments when weeds regain their nature as plants. Only now can I understand these drawings as simple moments of clarity. artclarity
