"Hello, World!"

Yes, I'm a geek for tradition. Here's a collaboratively created explanation of why the text above is meaningful for a first post: Stackoverflow.com: Where does Hello World come from?. The highest rated answer, from Wikipedia, makes me a little sentimental because I learned C by reading Kernighan & Ritchie myself.

main()
{
        printf("hello, world");
}
