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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.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.

Raynos

In other words, the following asynchronous code:

var d = Domain.create()

d.on("error", function (error) {
    console.error("Error with the twitterverse:", error)
})

d.enter()

*nix on Windows

Options

If you would like to use *nix tools on Windows, you have two main options:

• Cygwin offers your typical Linux toolset (bash, ls, cd, grep, and the other core utilities) and a DLL that provides some Linux system emulation (signals, etc.). However, Cygwin tends to take the "everything but the kitchen sink" approach, so I generally prefer the second option, MSYS.

Once upon a time there was a user that wanted to install firefox.

The user tried to do pacman -S firefox but it didn't work. The all mighty pacman reported that firefox-3.2.4-1.i686.pkg.tar.gz could not be found on his mirror. So the user tried pacman -Sy firefox. It worked and the user rejoiced since he could once again go and troll /h/.

But all was not good. The user had made a grave error!

See, when the user told the almighty pacman to -Sy firefox, pacman did

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
