Плохой код - это норм... типично
Sep. 21st, 2015 12:51 pmThere’s a kind of cognitive dissonance in most people who’ve moved from the academic study of computer science to a job as a real-world software developer. The conflict lies in the fact that, whereas nearly every sample program in every textbook is a perfect and well-thought-out specimen, virtually no software out in the wild is, and this is rarely acknowledged.
To be precise: a tremendous amount of source code written for real applications is not merely less perfect than the simple examples seen in school — it’s outright terrible by any number of measures.
Due to bad design, sloppy or opaque coding practices, non-scalability, and layers of ugly “temporary” patches, it’s often difficult to maintain, harder still to modify or upgrade, painful or impossible for a new person joining the dev team to understand, or (a different kind of problem) slow and inefficient. In short, a mess.
Of course there are many exceptions, but they’re just that: exceptions. In my experience, software is, almost as a rule, bad in one way or another. And lest I be accused of over-generalising: in more than 20 years I’ve done work for maybe a dozen companies, almost all of them in the banking industry and many of them household names.
The technology people employed at these companies are considered to be the very best, if only because the pay tends to be so good. I’ll play it safe and stick to my actual experience in the financial sector even though I'm convinced this state of affairs is not limited to that one industry.
