It has been a while since I upgraded the key components of my application stack. This decision was driven by a desire to use PostGIS is a current project, and it appears that MacPorts has designed the latest version of PostGIS to work with PostgreSQL 9.2.
With an upgrade to Mac OS X 10.8 (Mountain Lion), PHP's sendmail() inexplicably ceased working. I knew that a number of things got re-defaulted (like /etc/paths) but this seemed a bit different.
One of the ideas behind the Istarel Workshop Application Framework is workflows that represent common ways to interact with data. As I work on various projects, new workflows often suggest themselves. In most cases, these potential workflows are really pretty specific to an application. Sometimes, however, a workflow presents itself that could have fairly wide applicability. When that happens, I tend to build the workflow class and add it to the framework.
