Data Hiding in C

March 2nd, 2008

Object-oriented programming languages are described as supporting encapsulation, polymorphism, and data hiding. They provide powerful features that allow software components to be designed and implemented for change. Observing the mechanisms in an object-oriented programming language can potentially lead to a parallel implementation in a procedural language. This allows some object-oriented design knowledge that has been […]

Functions, Parameters, and Global Variables in C

February 4th, 2008

When I define interfaces to the functions that I implement, I try to be explicit about the variables that the functions will examine and modify. From time to time, a global variable is necessary, and I typically employ intermediary functions for accessing such a variable. Avoiding the direct use of global variables within functions is […]

Developing Amidst Change

December 12th, 2007

Lately, I have been working as a lead developer on a software module for a reasonably sized project. What seemed to be a task that appeared to require no more than three weeks has turned into something that has spanned four months and may include an additional two months for the provision of integration support. […]

Know Your Nomenclature

It’s very hard to discuss software engineering topics with respect to a given language when there’s some confusion between “function overloading” and “function overriding.”

Conveying Progress through Mockup Subchannels

October 15th, 2007

Kathy Sierra’s Don’t Make the Demo Look Done provides excellent advice for conveying the state of a project while presenting the project’s functionality. It also discusses advantages such as improved user feedback. With a very rough presentation, users will be comfortable providing inputs on significant system features rather than the particular fonts used in the […]
