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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.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

| # brew-services(1) - Easily start and stop formulas via launchctl | |
| # =============================================================== | |

| # [<sudo>] `brew services` `list`<br> | |
| # [<sudo>] `brew services` `restart` <formula><br> | |
| # [<sudo>] `brew services` `start` <formula> [<plist>]<br> |
Most of the time simple output statements using warn, raise, or a logger will help you find your issue. But sometimes you need the big guns, and that means ruby-debug.
The ruby-debug package has had some rocky times during the transition from Ruby 1.8.7 to 1.9.2 and beyond. But now, finally, the debugger is reliable and usable.
