Have fun with the AMI containing the examples from my latest Ruby book
I have Ruby, Rails, Sesame, Redland, AllegroGraph, D2R, Hadoop, Solr, PostgreSQL, Tomcat, Nutch, etc. pre-installed and configured. I use this AMI for new projects and for new experiments because it contains most of the tools and frameworks that I use. If you know how to use Amazon AWS, it is easy to clone your own copy with whatever additional software you need, hook up a persistent disk volume, etc. If you have not yet learned how to effectively use AWS, this might be a good time to do so. I like AWS because I can start a server, use it for development all day, and have it cost less than a dollar.
There are README files for the examples. For more details on how the examples work, please consider buying my book if you have fun with the AMI.
