Jenkinsfile idiosynchrasies with escaping and quotes
node {
echo 'Results included as an inline comment exactly how they are returned as of Jenkins 2.121, with $BUILD_NUMBER = 1'
echo 'No quotes, pipeline command in single quotes'

echo 'Double quotes are silently dropped'
sh 'echo "$BUILD_NUMBER"' // 1

echo 'Using two backslashes, the quotes are preserved'
sh 'echo \\"$BUILD_NUMBER\\"' // "1"

Promise protips - stuff I wish I had known when I started with Promises
// Promise.all is good for executing many promises at once
Promise.all([
promise1,
promise2
]);
// Promise.resolve is good for wrapping synchronous code
Promise.resolve().then(function () {
if (somethingIsNotRight()) {
throw new Error("I will be rejected asynchronously!");

I feel the need to have a little rant about MooTools and ES7 and the whole 'Array.contains' hoo-hah.

When MooTools came out in 2006, the most popular framework was Prototype. As the name suggests, it extended prototypes, as did MooTools. People still referred to making websites with JavaScript as 'DHTML', there was no trim method on strings, there wasn't even a forEach method on arrays. JavaScript was a crippled language. IE6 ruled the waves.

MooTools, Prototype, Dojo, Base2 - they made the language usable, even fun, to work with. By using an incredible feature of JavaScript, prototypical inheritance, we were able to add features to the language that made it palatable.

Be it simple methods like number.toInt, string.trim, array.forEach, or familiar programming constructs such as Class, MooTools and its ilk took JavaScript from something impossible to work with to something that you could properly use to build awesome sites, and even apps - Microsoft, IE and desktop ruled everything, and the concept of a 'we

How to capture "aui-editable" widget's "stopEditing" only once? The problem was that the "stopEditing" fired every time used clicked outside of the widget (which is not good if you want to send an AJAX request on blur event). Alloy UI v1.0.1
// editable is an aui-widget instance
editable.after('startEditing', function(ev1){
// some code here
// subscribe here, event will fire multiple times,
// but captured only once,
// it will be reattached next time the widget is editted
editable.once('stopEditing', function(ev2) {
// sent AJAX here!
});

A new user's guide to SublimeText 2. Estimated reading time: 2 mins. Estimated workthrough time: 12 minutes.

Make it useful

  • Install Package Control. For SublimeText 2, paste the following in Terminal:
import urllib2,os; pf='Package Control.sublime-package'; ipp = sublime.installed_packages_path(); os.makedirs( ipp ) if not os.path.exists(ipp) else None; urllib2.install_opener( urllib2.build_opener( urllib2.ProxyHandler( ))); open( os.path.join( ipp, pf), 'wb' ).write( urllib2.urlopen( 'http://sublime.wbond.net/' +pf.replace( ' ','%20' )).read()); print( 'Please restart Sublime Text to finish installation')

From here on out, use Package Control to install everything. +Shift+P, then type Install to get a list of installable packages you can 'livesearch through. After installing plugins, they should be running.
