The #1 Rule of API Design

I just wrote this article on API design for Elsevier’s SciTech blog. It talks about the importance of hiding implementation details and covers information hiding techniques for C++, Objective-C, and Python, such as the pimpl idiom and class extensions. The article includes a discount code for 40% off my book, in case you’ve been waiting for the price to come down before buying it!  Check it out at:
