# If your workers are inactive for a long period of time, they'll lose | |
# their MySQL connection. | |

# This hack ensures we re-connect whenever a connection is | |
# lost. Because, really. why not? | |
# | |
# Stick this in RAILS_ROOT/config/initializers/connection_fix.rb (or somewhere similar) | |

# Description: Simple demo to showcase Redis PubSub with EventMachine | |
# | |
# Update 7 Oct 2010: | |
# - This example does *not* appear to work with Chrome >=6.0. Apparently, | |
# the WebSocket protocol implementation in the cramp gem does not work | |
# well with Chrome's (newer) WebSocket implementation. | |
# | |
# Requirements: | |
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby |
#!/bin/sh -e | |
# | |
# Usage: browser | |
# pipe html to a browser | |
# e.g. | |
# $ echo '<h1>hi mom!</h1>' | browser | |
# $ ron -5 man/rip.5.ron | browser | |
if [ -t 0 ]; then | |

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.
You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf
using homebrew.

There is a lot of confusion as to how to get good ADXL graphs. For many, the issue is printer build and rigidity. For others, there is often an issue with ADXL mounting or noise. Like all of my guides, this is targeted at people chasing the highest performance with quality. If your quality and speeds are fine for you, stop reading as this guide isn't for you.
There are a few parameters that play into your measured values and this will break down the most straightforward. Broadly, they are mass and stiffness. This explanation will not be true in every single instance, and is definitely not PhD level physics, but should at least help with the broad understanding of what your printer is doing.
The easiest way to think about it is if you start by thinking of your printer as an undamped simple harmonic oscillator.
