About naming things, in the computer science world, there is this often repeated saying, as well as countless books and articles about naming things, often contradicting each others. From coding style guides to URL schemes. But on the other side, there is administration. I work on projects with names like FRPPX21, in category PX23, same idea for tax forms, and just about everything administrative. Should I write code with variable names like that, I would be yelled at by the unfortunate guy who gets to read it.
