How to become a programming expert

October 29, 2009

I just finished reading a very interesting paper by K. Anders Ericsson, Michael J. Prietula and Edward T. Cokely called Making of an Expert. Ericsson, a Swede, is “widely recognized as one of the world’s leading theoretical and experimental researchers on expertise” according to Wikipedia.

The paper sums up what seems to be the general idea in contemporary psychology of what it takes to become an expert in any field: deliberate practice for an extended period of time (10.000 hours or 10 years at a minimum), constantly throwing yourself at new challenges, having experts/teachers/supervisors around you etc. It also states that “across a wide range of experts, including athletes, novelists and musicians, very few appear to be able to engage in more than four to five hours of high concentration and deliberate practice at a time”. Finally I don’t have to feel guilty about not being able to perform complicated programming tasks after 2 o’clock anymore! What a relief.

The authors also give a nice tip of how to improve your skills on your journey to becoming an expert, by trying to replicate masters in the field and then compare your result to theirs, analyzing the differences and drawing conclusions upon that:

“Say you have someone in your company who is a masterly communicator, and you learn that he is going to give a talk to a unit that will be laying off workers. Sit down and write your own speech, and then compare his actual speech with what you wrote. Observe the reactions to his talk and imagine what the reactions would be to yours. Each time you can generate by yourself decisions, interactions, or speeches that match those of people who excel, you move one step closer to reaching the level of an expert performer.”

This apparently translates to any job. It’s truly inspiring, and I believe a good way for programmers to start is by looking at the expert programmers around the world. Read their books, understand how they think, and mimic it until you know it by heart, then analyze it. Memorizing a code kata seems like a good way to add to your 10.000 hours of deliberate practice

Here are two katas to help you get started right now:
Robert Martin’s Bowling Game Kata
Robert Martin’s Prime Factors Kata

See you in 10 years!
