Every once in a while I interview a new computer science graduate for a developer position. I prefer to ask the kind of questions that will let me see how they think about programming, if they think for themselves and if they are passionate about it.
Usually when I get to object oriented programming and I [...]
Designing the error path in the code is not the most entertaining part of a programmer’s job. We are focused on coding the solution, the success path, and the damn exceptions stand in the way demanding to be handled. What makes it even harder and murkier is the lack of well established rules for what [...]
While developing complex systems lots of failure situations require handling and without proper planning chaos can conquer your code.
A number of simple principles can create order and reduce complexity. And the result can be real software quality.
Good exception handling doesn’t happen by chance. It is designed and planned and when done properly it is one of the main roads to the software “Holy Grail” - quality and reliability.
But leave it to chance and soon all hell breaks loose.
UML lost the programmers. There is no doubt about it… in my mind. And when a software design technology loses the programmers it fades away no matter what the academia thinks. This happened because UML was pushed in a direction that most code writers don’t like: it started to look a lot like bureaucratic paper [...]
