MySQL privileges update for creating procedures, functions, etc.

After creating a new user you need to update his privileges to grant creation of procedures, functions and so on. Here is a SQL for this.

Select_priv="Y", Insert_priv="Y", Update_priv="Y", Delete_priv="Y", Create_priv="Y", Drop_priv="Y", Reload_priv="Y", Process_priv="Y", File_priv="Y", References_priv="Y", Index_priv="Y", Alter_priv="Y", Super_priv="Y", Create_tmp_table_priv="Y", Lock_tables_priv="Y", Execute_priv="Y", Create_view_priv="Y", Show_view_priv="Y", Create_routine_priv="Y", Alter_routine_priv="Y", Event_priv="Y", Trigger_priv="Y"
WHERE user = "xxxxx";

jQuery executes error function even on success (200) status

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. After checking the code, googling, reading, debugging, taking a lunch, debugging again and again I saw that I was using res.json() and not res.jsonp() (added in Express 3.x). Change of one line and everything is working back again.

So - if your node.js + express 3.x returns jsonp, please, use res.jsonp() instead of res.json()
