A collection of Splunk recipes for Heroku logs. Instructions for setting up Splunk Storm with Heroku can be found here. For the vast majority of these recipes you'll need to have enabled the Heroku labs feature, log-runtime-metrics, for your application.

This is a little trick I use to spin up the packages instalation on Debian/Ubuntu boxes in Vagrant.
I add a simple function that checks if a directory named something similar to ~/.vagrant.d/cache/apt/opscode-ubuntu-12.04/partial (it may have another path in Windows or MacOS) and create the directory if it doesn't already exist.
def local_cache(basebox_name)
cache_dir = Vagrant::Environment.new.home_path.join('cache', 'apt', basebox_name)
partial_dir = cache_dir.join('partial')
partial_dir.mkdir unless partial_dir.exist?
