I’ve finally made it to my first Zendcon. Its nice to see some familiar faces and also nice to put new faces to familiar names.
I gave my maintainable PHP talk this morning. I love doing this talk. Thanks to everyone who attended. I’ve put the slides (pdf) up on my talks page.
Much of the material is based on Test Pattern columns that I’ve written for php|architect. Here are some of the specific columns.
Organizing For Change
This is where I developed the outline for the talk
This is a more in depth discussion of code reuse and dependency injection
This is where I talk about coupling, layered design and abstraction
A Closer Look at Cohesion
This is where I developed my explanations of cohesion and the single responsibility principle
Searching the Code
Good designs are searchable
One thing I like about both writing on and presenting on the same material is that I get feedback from the presentations that I can put back into the writing and vise versa. I’m looking forward to finding some better ways to explain layering and the depend on abstractions principle. If you saw the talk, was there anything you particularly liked or needed work? Leave a comment here or on the joined.in page.
Here are some of the books I mentioned in the talk.
PHP in Action: Objects, Design, Agility
This is a really good next step if you’re interested in maintainable code, testing, and object oriented design.
Refactoring: Improving the Design of Existing Code
This is the classic treatment of Refactoring. Probably everyone considering themselves a professional programmer should read this. The examples are in Java, though.
Working Effectively with Legacy Code
This is a good book if you want to start testing and refactoring in a large system that doesn’t currently have tests. Again, the examples are in Java.
I sat in on the PHP Code Review talk this afternoon. I thought it was a great complement to my talk. I tend to be a bit theoretical and this talk was very practical, but we covered a lot of the same principles. Nice talk. Nice scheduling, Zend.
I’m really looking forward to tomorrow. Unfortunately, I have to go back to work on Wednesday.
