It’s frustrating that we, programmers, write bugs in our code.\ \ One way to figure out how to avoid writing bugs (or, more realistically, write less bugs) is to understand where do bugs come from.\ \ Recently I realized that there are only two sources of software bugs:

• ignorance
• carelessness\

Probably not the greatest of insights, but I haven’t seen it spelled out this way before.\ \ Since it seemed like a topic bigger than a blog post, I’ve written up a longer article about where do bugs come from and how to avoid them.
