Auto Mapping a JDBC ResultSet to JSON
// convenient Spring JDBC RowMapper for when you want the flexibility of Jackson's TreeModel API
// Note: Jackson can also serialize standard Java Collections (Maps and Lists) to JSON: if you don't need JsonNode,
// it's simpler and more portable to have Spring JDBC simply return a Map or List<Map>.

Enable key repeat in Apple Lion for Sublime Text in Vim mode
# Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key
# that enables you to choose a character from a menu of options. If you are on Lion
# try it by pressing and holding down 'e' in any app that uses the default NSTextField
# for input.
#
# It's a nice feature and continues the blending of Mac OS X and iOS features. However,
# it's a nightmare to deal with in Sublime Text if you're running Vintage (Vim) mode,
# as it means you cannot press and hold h/j/k/l to move through your file. You have
# to repeatedly press the keys to navigate.

Grunt Events
/*
* A) Simple Watch Events
*/
module.exports = function(grunt) {
grunt.initConfig({
nodeunit: {
files: ['test/**/*.js'],
},
watch: {
test: {

Problem

Some tasks utilize the watch to trigger an event, ie: live reload. With Grunt v0.3, those tasks on first run would create a variable, ie servers. Then subsequently ran by the watch task would check if the variable exists and then use it. Since the new watch spawns tasks, this is no longer possible.

Solutions Proposed

A) Have watch trigger a grunt.event
