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.
