I guess now it makes sense to approach it from the perspective of programming: What’s programmer’s deep practice? Unsurprisingly, inspiration can be found in the great japanese culture, people who highly value discipline and self improvement. Specifically i’m talking of martial arts. If you were to learn, say, karate you would go to a dojo and perform katas. If you happen to be a programmer, you can go to a coding dojo and practice code katas.

Code katas, a term first coined by Pragmatic Programmer Dave Thomas, are small programming exercises geared to hone a specific programming skill. Traditionally, they tend to be algorithmic like parsing or visiting graphs but could as well aim to improve understanding of particular programming paradigms, like functional or object oriented, or a specific language. Also, as remarkably pointed out by Matteo, katas can be crafted to master a certain technology like web or database. While, as you may guess, Coding Dojos are sites, groups or communities which propose and maintain collections of katas hopefully with solutions and reviews.

So, how do you practice? I suggest you solve a kata, review your work, compare it to other solutions, share your code with others and discuss it. Then solve it again trying to take a different path, balance pros and cons, then solve it again and again, until you feel you internalized the essence of the problem. Finally, you can move to another kata. If it feels like a lot of work, then you got it right. No question mastership requires time and effort but, then again, masters are those destined for greatness.
