Code Snippet Of the Day (CodeSOD) features interesting and usually incorrect code snippets taken from actual production code in a commercial and/or open source software projects.
Tobbi sends us a true confession: they wrote this code.
The code we're about to look at is the kind of code that mixes JavaScript and PHP together, using PHP to generate JavaScript code. That's already a terrible anti-pattern, but Tobbi adds another layer to the whole thing.
Dates are messy things, full of complicated edge cases and surprising ways for our assumptions to fail. They lack the pure mathematical beauty of other data types, like integers. But that absence doesn't mean we can't apply the beautiful, concise, and simple tools of functional programming to handling dates.
I mean, you or I could. J Banana's co-worker seems to struggle a bit with it.
Today's Java snippet comes from Capybara James.
The first sign something was wrong was this:
Henrik H sends us a short snippet, for a relative value of short.
We've all seen this method before, but this is a particularly good version of it:
State machines are a powerful way to organize code. They are, after all, one of the fundamental models of computation. That's pretty good. A well designed state machine can make a complicated problem clear, and easy to understand.
Chris, on the other hand, found this one.
David G saw a pull request with a surprisingly long thread of comments on it. What was weirder was that the associated ticket was all about adding a single parameter to an existing method. What could be generating that much discussion?
How could adding an argument add to an argument?
