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.

revisiting architectural blogging An Article by Alan Jacobs blog.ayjay.org I have appropriated from Brian Eno and others the distinction between architecture and gardening, and have described my blog as a kind of garden. But lately I’ve been revisiting the architecture/gardening distinction and I have come to think that there is something architectural about writing a blog, or can be – but not in the sense of a typical architectural project, which is designed in advanced and built to specifications. Rather, writing a blog over a period of years is something like building the Watts Towers. Simon Rodi didn’t have a plan, didn’t even have a purpose: he just started building. His work was sustained and extended by bricolage, the acquisition and deployment of found objects – and not just any objects, but objects that the world had discarded as useless, as filth. You put something in here, then something else, you discover, fits there … over time you get something big and with a discernible shape. Not the regular shape envisioned in architectural drawings, but nevertheless something that can be pleasing or at least interesting to look at – an organic and irregular shape. A geometry of irregular forms. architectureblogginggardens
