Programmer Humor

Outside of the for loop counters i and j, short variable names are awful. Coming back to old code written with abr var nams is like talking to someone in the military who just constantly throws out jargon and acronyms that they know you don't know.

But so are Java style ObserverFactoryManagerTemplateMachinistTemplater names.

There's a sweet middle ground of short, but actually descriptive name. Sometimes it's not possible but that's usually a code organization / language / framework smell.

Too short variable names is usually a sign that you need to use a proper ide, with auto complete, or that you need to use a proper build process that will minify your code after the fact.

Too long names are usually a sign that your module of code (function, class, namespace, etc) is too large, or that your language/framework naming conventions are too strict, or the language doesn't encapsulate scope properly.
