 * Nunjucks + Express 
 * I couldn't find anything that helped me setup the enviornment
 * correctly for these in the latest vesion of Express 4 (at the time
 * of writing this).
 * 
 * This Gist for those that want to keep using Nunjucks with Express 4.
 * This also goes over working with a Nunjucks environment to use custom
 * filters, extensions, etc.

React Native Folder Structure

Motivations

• Sharing what has worked for me in different React Native projects
• Reusing screens in different parts of your app
• Easy to work separately in a feature
• Add an extra level (nested folder) only when necessary
• Don't overuse index.js for everything

PostgreSQL: Fuzzy search with levenshtein()

Ever wanted to implement a “Did you mean?” feature in your search results? Google is said to have greatly increased its user engagement with it. Here is how to implement it simply in Postgres (v9.1+):

Install the extension:

CREATE EXTENSION fuzzystrmatch;

	 function RemoveAccents(strAccents) {
		var strAccents = strAccents.split('');
		var strAccentsOut = new Array();
		var strAccentsLen = strAccents.length;
		var accents = 'ÀÁÂÃÄÅàáâãäåÒÓÔÕÕÖØòóôõöøÈÉÊËèéêëðÇçÐÌÍÎÏìíîïÙÚÛÜùúûüÑñŠšŸÿýŽž';
		var accentsOut = "AAAAAAaaaaaaOOOOOOOooooooEEEEeeeeeCcDIIIIiiiiUUUUuuuuNnSsYyyZz";
		for (var y = 0; y < strAccentsLen; y++) {
			if (accents.indexOf(strAccents[y]) != -1) {
				strAccentsOut[y] = accentsOut.substr(accents.indexOf(strAccents[y]), 1);
			} else
