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.

Jacked in In digital design, products and services are frequently imagined and implemented placelessly: as if the consumer were jacked into The Matrix, and considering this product or that product from among an infinite set of choices at an infinitely-provisioned mercantile. The things we make are good, by this way of reasoning, if they fit the market’s demand. designsoftware
Immer wieder My attitude toward Alexander’s teachings prior to experiencing the places and spaces realized in his practice was akin to what Alan Watts said about certain teachings in The Bible: Sometimes, as St. Paul pointed out, commandments are not given in the expectation that they will be obeyed, but in the expectation that they will reveal something to those who hear them. Today, my answer is unequivocal. My interpretive lens: literal. Time and again, across cultures and continents and islands and oceans, in five different places now I’ve examined the evidence, and am persuaded. Nicht nur einmal: immer wieder. religionteaching
But what if it is? Occasionally, one or two students out of sixty would take this task [of timeless thinking] up with some seriousness, and before too long would visit me in office hours to see if I could relieve them of their distress. They needed me to assure them that what Alexander says in his books isn’t…you know…real. For a number of reasons, not the least of which being the seeming incompatibility between how they’d been taught to think about design and what these teachings insist one must do in order to be, as they might say, “doing it right.” And having never been to any of Alexander’s buildings, I’d simply turn the question around and ask “but what if it is real?” reality
