echo ‘Hello World!’;

ah, the inevitable first post, sometimes funny, sometimes informative, always trite.

funny:  “Unix is user friendly. It’s just very particular about who it’s friends are.”

informative: “In computer science, tree-traversal refers to the process of visiting (examining and/or updating) each node in a tree data structure, exactly once, in a systematic way. Such traversals are classified by the order in which the nodes are visited.” — wikipedia

trite: see post title.
