Pat and I are back with another installment of our weird little video podcast! Today we talk about the Single Responsibility Principle, which is at the heart of SOLID. SRP pushes everything out into little classes, and if you want to get anything complex done (like, for instance, you might find in any real program with more than 10 lines of code), you have to build a sort of aggregator object or manager class. Our key question for this podcall is “Even though SRP makes this aggregator class necessary, does the aggregator class itself violate SRP?”
As always we had a great time talking about it. Viewers will be happy to know that we kept the fart jokes to a minimum (I opted to go with Registered Sex Offender humor instead). Viewers distressed by the amount of airtime my cats got last time (and you know who you are, George S. from Utah) will be happy to know that my cat only farts in the microphone once, and she gets less than 10 seconds of airtime doing it. Fair warning: she really works those 10 seconds.
