This gist contains everything you need to install StatsD and Graphite on CentOS 6.3. Unless I forgot something. If I did, shoot a reminder email to noah at one more bug dot com. **tl;dr: womm, ymmv, yolo.**

I (mostly) followed the steps shown in the [EZUnix wiki](http://www.ezunix.org/index.php?title=Install_statsd_and_graphite_on_CentOS_or_RHEL)

And I also referred back to [this gist by Michael Grace](http://geek.michaelgrace.org/2011/09/how-to-install-graphite-on-ubuntu/)

I would like to list out some of the points that differentiates GIT from SVN as a Version Control tool.

 1. Basic difference between the above mentioned tools are that SVN is a Centralized and GIT is a Distributed version control tool.
 
 2. Commit happens atomic in nature for SVN where as for GIT it's more like file versioning happens with every commit.

 3. GIT versions by storing the contents of the files for tracking history where as in SVN the basic data storage is done by creating a differences between the individual files for each change.

 4. GIT stores every changes in any of its sub-directories of its project structure within the .git folder that gets created only on the parent folder of the project structure where the git initialized a new git repository where as in SVN the .svn will be created in every sub-directories within the project structure to store the metadatas of each and every file and folder.

The machine that will host the git repository needs to be accessed by clients. A possible way to access a machine remotely is through SSH.

S3cmd tool for Amazon Simple Storage Service (S3)
=================================================

S3cmd is a free command line tool and client for uploading, 
retrieving and managing data in Amazon S3 and other cloud 
storage service providers that use the S3 protocol, such as 
Google Cloud Storage or DreamHost DreamObjects. It is best 
suited for power users who are familiar with command line 
programs. It is also ideal for batch scripts and automated 
backup to S3, triggered from cron, etc.

Workshop:
 
-> Introduction to Go Continuous Delivery Software -- ThoughtWorks pitching in it's paid tool.
-> Linux containers (LXC) and future of software delivery -- Getting a lot of attention, perhaps due to Docker
-> SELinux for the Uninitiated --  Interesting...why would I choose to enable SELinux? Personally I end up disabling it each time. :)
-> Continuous deployment with Fabric -- Couldn't figure out what was the ISP..Chef offers it already and a lot more. [http://www.slideshare.net/tanihito/automated-deployment-with-fabric]
-> Continuous Delivery using Jenkins - Jenkins is an aswesome tool..create as a CI tool but easily extendible to CD as well.. my own presentation from few months back [http://www.slideshare.net/bhalothia/jenkins-a-complete-solution]
