Pins for programmers, geeks, and compsci nerds
You Had Me At Hello World
"Hello World" is a really old tradition, by tech standards--the Jargon File dates it back to the classic C/Unix days. It's the first test message you print to standard output when you're learning a new programming language.
These days, you might also throw a "Hello World" in a <p> element real quick when you're checking whether your new website's DNS has propagated or your WordPress install is displaying posts cleanly. Maybe it's even what you write in a sample doc when you want to make sure your printer's hooked up right. Basically, it's the minimalist Lorem Ipsum of the programmer world.
And now it's a pin. For fashion. Geeky, geeky fashion.
Progress Incremented
The ++ symbol (aka the incrementor) is often used to express approval or "good job!" in coding circles. Get this pin to celebrate your progress.
Magic / More Magic
The Magic / More Magic Switch is a reference to a piece of obscure old-school hacker lore. Some geek long ago (in the PDP-10 era!) managed to make a switch that, in theory, really shouldn't have been able to do anything, but because of a fluke of electrical engineering it'd crash the computer if you flipped it from "more magic" to just "magic."
Fortunately, the switch on the pin will stay on "more magic" forever, because that's how it's drawn. An excellent good-luck charm for your favorite computer engineer.
Inadvisably Applied JS
JavaScript (derogatory) -- but that doesn't mean we'll stop reaching for it to do... probably too much, from little bits of swoopy animations on a website's front end to whatever random thing you need to hack together with a scripting language real quick.
The design is very human. Is it scalable? No. Is it maintainable? No. Is it portable? ...Not really. But at least the pin is! Get it here.
