tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

start new with session name:

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.

	var _ = require('underscore'),
	util = require('util');

	// intercept stdout, passes thru callback
	// also pass console.error thru stdout so it goes to callback too
	// (stdout.write and stderr.write are both refs to the same stream.write function)
	// returns an unhook() function, call when done intercepting
	module.exports = function interceptStdout(callback) {
	var old_stdout_write = process.stdout.write,
	old_console_error = console.error;

	Once upon a time there was a printer who lived in the woods. He was a
	lonely printer, because nobody knew how to configure him. He hoped
	and hoped for someone to play with.

	One day, the wind passed by the printer's cottage. "Whoosh," said the
	wind. The printer became excited. Maybe the wind would be his
	friend!
