pocketknife is a devops tool for managing computers running chef-solo, powered by Opscode Chef. Using pocketknife, you create a project that describes the configuration of your computers and then deploy it to bring them to their intended state. With pocketknife, you don't need to setup or manage a specialized chef-server node or rely on an unreliable network connection to a distant hosted service whose security you don't control, deal with managing chef's security keys, or deal with manually synchronizing data with the chef-server datastore. With pocketknife, all of your cookbooks, roles and nodes are stored in easy-to-use files that you can edit, share, backup and version control with tools you already have.

Rexpl is an interactive bytecode console for Rubinius

EventMachine implements a fast, single-threaded engine for arbitrary network communications. It's extremely easy to use in Ruby. EventMachine wraps all interactions with IP sockets, allowing programs to concentrate on the implementation of network protocols. It can be used to create both network servers and clients. To create a server or client, a Ruby program only needs to specify the IP address and port, and provide a Module that implements the communications protocol. Implementations of several standard network protocols are provided with the package, primarily to serve as examples. The real goal of EventMachine is to enable programs to easily interface with other programs using TCP/IP, especially if custom protocols are required.
