States and their abbreviations are among my favorite kinds of data - they almost never ever change and, as such, you can hard code all that information into your app. I mean, why bother fetching it from the database every page load? That's just wasted CPU cycles.

On one hand, this Java class Jim found is just another instance where somebody made constants like this:

Securing Input

2014-08-14
We all know that many developers have difficulty in dealing with built-in concepts like dates and times, and that for and switch statements don't necessarily have to be used with each other. However, validating a piece of input is usually more straightforward. You compare what you got to what was expected.
While working on his company's reservation manager, Stephaan stumbled upon some PHP code that calculated the date values for tomorrow ($morgen) and the day after tomorrow ($ubermorgen). Something about the code struck him as ... wrong.

Literal Scripting

The HR team at Initrode were a happy bunch, casting their nets into the perpetual stream of eager undergrads from nearby WTF U. It was a summer tradition at Initrode to invite a school of juniors to get a taste of their future by spending the long, sun-drenched afternoons of their dwindling youth hunched in cubicles.
The question of whether you should include in-line comments in your code is a running one in the development community. To some, they are part of the process of ensuring the ongoing maintainability of a codebase. To others, comments are the spawn of satan, lower than cockroach droppings, or slightly above a Justin Bieber song.
We've all heard of threads. No, not the stuff hanging loosely from your clothes. I mean threads, as in multitasking. Most modern languages have all sorts of nifty facilities that allow you to create, manipulate and destroy them at will and with minimal effort. There are even abstractions that will manage a set of threads for you, so that you can spawn a bunch of tasks, and let them tell you when they're done. You can synchronize them yourself. You can put up cyclic barriers to make them all wait at a specific point in the code. You can make them return a value when they're done. Or you can just spawn them and let them run all by their lonesome. Of course, not everyone trusts the built-in facilities... Now you might expect this sort of thing from Joe Offshore, but not from certain huge, blue companies.
