This blog post has helped me clean up my postgres development environment on Mac. So making a copy!

How completely uninstall PostgreSQL 9.X on Mac OSX

This article is referenced from stackoverflow:

If installed PostgreSQL with homebrew , enter brew uninstall postgresql

If you used the EnterpriseDB installer , follow the following step.

killmenot

module.exports = {
  foo: function (req, res, next) {
  },
  bar: function (req, res, next) {
  }
};

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

var Article = require('../../../models/article');

Those suck for maintenance and they're ugly.

Possible solutions

killmenot

!function(root, _, undefined) {

	var Disposable = root.Disposable = function() {
		this.disposed = false;
	};
	Disposable.prototype = {
		_dispose: function() {
			if (!this.disposed) {
				this.dispose();
				this.disposed = true;

console.log wrap resolving for your wrapped console logs

I've heard this before:

What I really get frustrated by is that I cannot wrap console.* and preserve line numbers

We enabled this in Chrome DevTools via blackboxing a bit ago.

If you blackbox the script file the contains the console log wrapper, the script location shown in the console will be corrected to the original source file and line number. Click, and the full source is looking longingly into your eyes.

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.

JavaScript Testing with Grunt, Mocha and Chai

In the following post I would like to introduce one way how you can setup your testing workflow for JavaScript development. The central components in the testing environment are Grunt, Mocha and Chai that I will cover from the introduction and installation of each component to the cooperation of all components for the execution of tests.

If you are already an experienced Grunt user and just look for the Gruntfile.js and the Mocha / Chai setup just skip the central components section and skip to the installing components part.

You can find the sample project with all code at GitHub on: https://github.com/maicki/sample-js-testing-grunt-mocha-chai
