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.

Designing with code An Article by Matthew Ström matthewstrom.com Recently I’ve had a few opportunities to use code to create design. In two of my bigger projects at The Wall Street Journal, writing code has led to new ideas. Problems that typically plague early designs — e.g. “how does this look with real content?” — are easy to solve. By exploring visual ideas directly in code, I’ve started to see the amazing potential of code as a design tool. ColophonPainting With the WebI never have engineers that aren't designers codedesign
