Development Process http://en.wikipedia.org/wiki/Programming_style http://martinfowler.com/articles/continuousIntegration.htmlegration.html http://en.wikipedia.org/wiki/Unit_testing htthttp://en.wikipedia.org/wiki/Revision_control Overview Unit Testing Source Control Coding Standards Continuous Integration Documentation

31. Development Process http://en.wikipedia.org/wiki/XUnit Unit Testing Why write unit tests? prevent regressions ensure software meets requirements tests help document what the software does XUnit pattern unit testing framework with equivalents in PHP, Java, Ruby, C#, and more XUnit is one of the most popular ways to test code

32. Development Process http://subversion.tigris.org/ http://git-scm.com/ http://www.github.comw.github.com http:/http://en.wikipedia.org/wiki/Distributed_revision_controlki/Distributed_revisi Source Control Why use source control? Keep track of changes you made Light-weight backup Great for collaboration, even if there is only one of you now Common SCM (Source Code Management) tools Subversion (SVN) widely used, well-supported by tools client-server model, integrates well with Apache Git distributed model, trendy somewhat high learning curve, especially if youre used to SVN or CVS

33.
