Windows XP as your screensaver!

Overview

When xscreensaver starts screen saving, instead of a boring screen saver it spawns a small shell script. This shell script starts a new X server with a very minimal awesome window manager and unfreezes a kvm virtual machine containing a Windows XP on that X server, ready to be used by any passersby. To unlock the screen, you need to switch back to the VT where your usual X is running. As soon as the screen is unlocked, xscreensaver sends a SIGTERM to the shell script which in turn stops all the X servers, window managers and virtual machines it launched and resets the VM image. Should the VM exit before the screen is unlocked because somebody pressed "Shut down" the VM image is reset and the VM restarted.

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

Better Jasmine Tests With this

On the Refinery29 Mobile Web Team, codenamed "Bicycle", all of our unit tests are written using Jasmine, an awesome BDD library written by Pivotal Labs. We recently switched how we set up data for tests from declaring and assigning to closures, to assigning properties to each test case's this object, and we've seen some awesome benefits from doing such.

The old way

Up until recently, a typical unit test for us looked something like this:

describe('views.Card', function() {

You have a git commit in your history that is causing a bug but you do not know which commit it is.
Here's how to use git bisect to find the commit that causes the bug.

# in the git root, start the git bisect
git bisect start

# mark current commit as bad
git bisect bad
