  A Baseline for Front-End Developers

I wrote a README the other day for a project that I’m hoping other developers will look at and learn from, and as I was writing it, I realized that it was the sort of thing that might have intimidated the hell out of me a couple of years ago, what with its casual mentions of Node, npm, Homebrew, git, tests, and development and production builds. Once upon a time, editing files, testing them locally (as best as we could, anyway), and then FTPing them to the server was the essential ...

  On Programming Deadlines

There are a lot of differences between programming, and programming professionally. The most notorious of which, is deadlines.DeadlinesWhen you're writing code for yourself, you can spend as much (or as little time) on it as you please--but when you're writing code for other people, you've got only a limited amount of time and resources to get the job done. In my experience, this typically leads to one of two situations:You've got to extend the deadline to finish the job properly.You've got to w...

When done right, requirements can be very useful. Unfortunately, if you spend much time working in the embedded world you quickly discover that there are a lot of bad requirements.

These variables differ from their normal counterparts in that each thread that accesses one (via its get or set method) has its own, independently initialized copy of the variable.

  What Separates Good Designers from Great Ones

Most of the design books you read, including my own, are about how to be a good, competent designer. They are about how to make strong, reasoned design decisions and about design methods and tools. But what they won’t—can’t—teach you is how to become a great designer. The only way to be a great designer is to produce great products. Everything else is…well, everything else. I’m convinced that the people who are great designers, while assure...
