“For the past few months, I’ve been exploring software design patterns, both at their roots and in their modern implementations. I’ve been exploring new languages and deepening my understanding of the languages that I already use. Man can I ever tell ya, it’s been exhilarating.
I started reading a new book last night, given to me by a CS professor who has been extremely kind to me. It was written in 1979, published by IBM: “Structured programming, theory and practice“. In the preface to the book, the authors discuss the beginnings of the software development field (originally an afterthought to hardware, and an error-prone, cut-and-try process) and its evolution into a true discipline where a programmer could solve a problem correctly, the first time, with no mistakes. I found one statement incredibly profound, contrasting ad-hoc spray-and-pray methods with true precision: “A programmer can gain 10 years of experience, or a programmer can get the same years experiences 10 times over.” Wow. How true.
If there is any fundamental evil in the profession of software, it must be that horrible trial and error loop that is the result of a lack of understanding – about the problem at hand (if it has even been defined), the tools at your disposal, existing solutions, or all three. When we allow ourselves to subsist in such a state, we waste the little time we have on this planet. We become triflers and busy bodies, always scurrying about in a rush yet never accomplishing anything of significance.
Have you ever met someone who has been in the field for years, yet still seems to have abilities only slightly better than that of a novice? I have. In contrast, have you ever met a “whiz” who seems to make incredible progress in short amounts of time? I’ve met a few of those as well.
In Daniel Coyle’s “The Talent Code: Greatness isn’t Born, it’s Grown,” the process of building skill is discussed and examined at length. The book opens with a story about a girl who does a month’s worth of practice in five minutes, without even knowing it. This seems like a fantastic claim from the outset, but as the book progresses Coyle makes his case. Coyle claims that while duration of practice is indeed important, the method of practice is a far more effective mechanism for building talent. Coyle examines Russian Women’s Tennis Champions, South Korean Golf Champions, Brazilian Soccer Players, World Class Musicians and Singers, Surfers, Chess players, elite magnet schools and more. His argument is that in all cases – elite performers don’t simply spend lots of time in their respective courts – they spend their time doing completely different things. Elite performers focus on developing a fluency with the fundamentals. They “chunk” their learning such that each piece is mastered independently of the whole.
I feel software development is a field where this is especially true. From my own experiences, I know that my greatest personal gains have come from:
- Deep study of fundamentals. Language fundamentals. Programming paradigms. Data structures. Repetition of those fundamentals.
- Application of those fundamentals in more holistic contexts.
- Closely examining (not just reading, but PORING OVER) code written by more capable programmers
Conversely, I can say that my own gains plateau when I find myself debugging code I don’t understand, using tools I don’t understand, and staying in my comfort zone (ie writing code and designing systems I already know how to write and design). The longer I subsist in this state, the harder it is to get back to doing it right. Complacency and ignorance breed the same.
CS Lewis states in the preface to “The Great Divorce” that “when a man faces a fork in the road and chooses incorrectly, he will never reach his desired destination by continuing. He must backtrack to where the error was made and begin again on the correct path.”
A programmer will never grow in a state of willful ignorance and repetitive, mindless busy work. A commitment to knowledge and understanding, being guarded against error, a passion for our craft; These are the building blocks of growth. This is how we evolve…quickly.”
