Starting a localization process for one of projects. Currently looking for localization of backbone and underscore parts. i18n plugin from require.js seems to do almost all that I need, but... there is a strange feeling that everything is too simple... Looking around on the web found some frameworks, projects but they don't offer anything that I can not get with a plain and simple require.js i18n

Just lost a couple of hours with this problems. jQuery was executing an error function regardless the jqXHR status. A little bit about setup: node.js + Express + Backbone + backbone.paginator + Underscore After upgrading to Express 3.0 an application that was working without any problems stoped to work. Problem - jQuery was always executing an error function for all ajax requests.

If you need to implement a MySQL PASSWORD() function in JavaScript - use http://code.google.com/p/crypto-js/#SHA-1 with 2 encodings. Here is an example: var password = "TestPassword"; var result = ("*"+CryptoJS.SHA1(CryptoJS.SHA1(password))).toUpperCase(); console.log("result : " + result); Result will be *0F437A73F4E4014091B7360F60CF81271FB73180.

If you are using <cfmenu> and <cfgrid> and you have an overlapping of the menu items by cfgrid header (a part of menu is hidden behind cfgrid header) you must add to your CSS a following style:#myMenuId .yuimenu { z-index: 300003;}This problem is caused by some "yui" CSS style with z-index set to 1, while grid related styles have z-index bigger than 200000.

When you need to have the a copy of the disk from one VM on the other:Power off  source VM, copy your .vmdk files to destination VM (probably you would like to change disk name and flat name - just rename your files and edit smaller .vmdk file to set correct name for flat file).Set new UUID for your copy of your original .vmdk file/usr/sbin/vmkfstools -J setuuid path_to_destination_VM/
