bunnymatic / safe_logger.js
Created November 12, 2010 01:11
Provide a tiny module that will allow for safe logging to console for browsers that allow it. For those that don't, don't log anything. Easily turned off with a debug switch which can be server generated (depending on environment dev/staging/prod) or no
var L = window.SafeLogger = window.SafeLogger || {};
//
// from server or on a specific page you want console data
// L.__debug__ = true
//
L.log = function() {
if (window.console && L.__debug__) {
// TODO: Chrome doesn't let us call apply on console.log.
// Interpolate variable arguments manually and construct
// a single-argument call to console.log for Chrome.

bunnymatic / bash function rebase_prep for git
Created January 5, 2011 18:16
This bash function, when run from your current branch will jump to master, pull and jump back to your current branch, leaving you all ready to rebase master and then merge branch into master. Add it to your .profile and roll on.
rebase_prep() {
git checkout master && git pull && git checkout -
}

bunnymatic / git alias for rebase preparation
Created January 5, 2011 20:39
Adding the rebaseprep line to your .gitconfig will give you the ability to prep for a rebase. The method jumps from the current branch into master, pulls the latest, and jumps back to your working branch. This leaves you all ready to rebase with master
[alias]
rebaseprep = !sh -c 'git checkout master && git pull && git checkout -'
