Many learn to program because they’re fascinated by—and talented at solving—the tricky logic puzzles involved. But those puzzles weren’t my top priority when I started programming. I can appreciate a good puzzle, but I got into programming because, originally, I wanted to build my own video games. I still loved…

There are only two hard things in Computer Science: cache invalidation and naming things. —Phil Karlton Naming is often called one of the most difficult problems in programming. Surely, at least once during a programming conference of your choice, and almost always by someone who has done a lot of programming…

Learning the basics of data structures is a rite of passage for new programmers. On their first day doing so, chances are they’ll encounter the idea of a “node”, and the idea of links between nodes. Both of these ideas can be used to organize data in innumerable ways…

I’ve noticed an unfortunate development habit of mine. I’m not the only one, so chances are if you’ve avoided this habit yourself, you’ve at least seen it elsewhere. This habit is over-secrecy in a project’s development. “Nobody can see it until it’s…

In every instance when I’ve said that I prefer to write my software in C, the response is—normally—raised eyebrows. Several dominant memes in the programming world make my position unpopular, and thus uncommon to find. I regularly hear, “why would you write new code in an unsafe systems language?”, “performance isn’t everything!”, and perhaps the most c…

Anyone who has written C has been in the situation—you write an enum, and sooner or later, you’d like to associate values of that enum with strings. You might want to log a value to plaintext in a human-readable form, or you might want to display the value in a user interface…
