A recent pair of articles from Dr. Dobbs reminded me of a famous line from Anna Karenina:
All happy families are alike, but each unhappy family is unhappy in its own way.
Paul Johnson argues that Tolstoy had it backward, that there is more variety in happy families. He argues that there are “obvious, recurring patterns in unhappy families” such as drunkenness and adultery. In any case, back to programming.
Are unhappy programmers all alike? Or happy programmers?
As for great programmers, Binstock says they have wide knowledge and good judgment of how to apply that knowledge. True, but not unique to programming.
But he also says great programmers have the ability to quickly switch between levels of abstraction. Such a skill could be useful in other professions, but it’s particularly useful in programming because software development requires knowledge of many different levels of abstraction. For example, data ranges from bits to terabytes, each with its own level of abstraction. Not many professions regularly have to think about phenomena at multiple resolutions ranging over 12 orders of magnitude.
As for bad programmers, Binstock lists a number of common traits but boils it down to this: “In my experience, at the core of bad programming is invariably a lack of curiosity.” I’d agree that a lack of curiosity explains a lot, but it leaves a great deal of unexplained diversity in bad programming.
