Write Great Code, Volume 1: Understanding the Machine

If you've requested an individual the key to writing effective, well-written software program, the reply that you've most likely gotten is "learn meeting language programming. " by way of studying meeting language programming, you find out how the laptop relatively operates and that wisdom might help you write higher high-level language code. a grimy little mystery meeting language programmers hardly ever admit to, notwithstanding, is that what you really want to benefit is laptop association, no longer meeting language programming. Write nice Code Vol I, the 1st in a chain from meeting language professional Randall Hyde, dives correct into desktop association with no the additional overhead of studying meeting language programming whilst. and because Write nice Code Vol I concentrates at the desktop association, now not meeting language, the reader will study in higher intensity these topics which are language-independent and of outrage to a excessive point language programmer.

Sample text

The best way to find out how a user thinks is to watch one. Ask a user to complete a task using a similar piece of software to what you’re developing. Make sure the task is a real one: “Add up a column of numbers” is OK; “Calculate your expenses for the last month” is better. ”—there’s a big clue in that question. Get the user to talk through his or her progress. Don’t interrupt. Don’t try to help. ” The first thing you’ll notice is that users do a core of things similarly. They try to complete tasks in the same order—and they make the same mistakes in the same places.

It follows, then, that everybody should agree on the coding standard, too—it does not help if one developer uses three spaces to indent code, and another uses four. 8 97 Things Every Programmer Should Know There exists a wealth of tools that can be used to produce code quality reports and to document and maintain the coding standard, but that isn’t the whole solution. It should be automated and enforced where possible. Here are a few examples: • Make sure code formatting is part of the build process, so that everybody runs it automatically every time they compile the code.

Companies can always send out our magic robots to “patch” the broken buildings and vehicles they sell. All of this points to a startlingly counterintuitive conclusion: our sole premise was a dramatic reduction in construction costs, with the result that quality got worse. It shouldn’t surprise us that the preceding story has played out in software. If we accept that code is design—a creative process rather than a mechanical one—the software crisis is explained. We now have a design crisis: the demand for quality, validated designs exceeds our capacity to create them.
