Module to wrap `console.group` around all methods
// A simple object with some methods,

var maths = {
square : function (value) {
// Validity checking
if (arguments.length !== 1) {
throw new Error('square: Requires one and only one argument');
}
if (typeof value !== 'number') {
throw new Error('square: Requires numeric argument');

a nice .emacs for when you are on a terminal. Respects scroll wheel events. Very useful when run inside of tmux and combined with this tmuxconf: https://gist.github.com/ftrain/8443744

My Heroku values

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

my nginx *.dev config - the first line in each file is the full path to the file because gists don't give enough context. see https://gist.github.com/neonstalwart/5246908 for some extra config for virtualbox (not included here because it's ugly)
