In the summer of 2009 I revisited my 2004 summer apprenticeship at Object Mentor. What follows is the original 2004 post and then some 2009 commentary.
Our payroll UML diagram (from yesterday) had some needless complexity but, other than that, it was fine. Well, mostly fine.
Lots more patterns today. Many of the patterns boil down to the server-client relationship.
My project for the afternoon was, of course, banging my head against the Linux box. Apache keeps insisting that I don’t have permission to run the install.php program, but everybody has permission to use it.
The big message I took away from Object Mentor that summer was that although patterns are cool and can help a lot, they add complexity. It’s a complexity/coupling trade-off.
