This week we discussed Factory Method, Adapter and Iterator plus made a start on Visitor.
Numbers were up a bit on last week and we used the Postgraduate Common Room for our session which was a nicer space than the class room for a seminar - I just hope we didn't disturb the other students in there.
6 students have now linked their blogs into this one via the comments link. Interestingly however they aren't linking in on the current week but on the week that first catches their eye.
I have now added Dr Sri's introductory patterns lectures to the unit web page which should be of help to the St Patrick's students.

Week 3
This week I've seen both the UoP students and the St Patricks students and given out the coursework to them all
Here in UoP we had a seminar looking at some of the material written by Richard Gabriel in his book Patterns of Software*. We had a good discussion about computing and patterns and then followed that up by looking at the Strategy pattern in some detail and an overview of Factory Method which we will come back to next week.
At St Patricks we concentrated on the coursework and I answered a wealth of questions about it. I also talked a little bit about the MVC pattern and about QWAN.
There is a huge range of material on the web about MVC (Model-View-Controller) including:
One of the classic papers on MVC is that by Steve Burbeck originally written in 1987:
For a discussion on QWAN, the Bead Game, symmetries, centers and carpets see: "The Bead Game, Rugs and Beauty" in Gabriel's book Patterns of Software (ibid) * . In addition Wikipedia gives a good overview of the concept of Quality Without a Name (QWAN).
And for something on the technical aspects of Qwan and pattern symmetries for software see James Coplien's symmetry papers at: http://users.rcn.com/jcoplien/bibliography.html
After my class at St Patricks Dr Sri gave me a copy of some of his lecture material and I will in the next few days add it into the PAFSD unit website.

- Applications Programming in Smalltalk-80(TM): How to use Model-View-Controller(MVC)
- And for some history about the development of the MVC pattern try:
- MVC XEROX PARC 1978-79
