TinkerBell is a application development tool for Ruby Web Dialogs. It can be used to develop GUI and Ruby code and a complete application. It works under rwdtinker, the core application for the rwdapplications. Rwdtinker can install and delete installed applets. This program uses the RubyWebDialogs GUI interface, and can be added to with drop-in applets. There are about 14 applets that can be installed. Context-sensitive help is on the windows and tabs.
ProcPile is a pure Ruby distributed computing cluster environment. Its goal is to allow fast prototyping on smaller datasets, especially those where serialization and deserialization are minor expenses relative to the core processing task. Once the algorithms are settled, you should be able to scale out to full production usage. At that point, you can replace the core processes with Ruby modules written in C (or Inline::C), or move the design to a more "grown-up" clustering environment.
Rcss implements CSS-SSC (CSS Server-Side Constants) in Ruby. Its features include the processing of rich CSS files using ERB templates, server-side constants, and server-side classes (preliminary). It plugs-in seamlessly to any Rails application but also allows the processing of Rcss files off-line using a command line executable.
BinBackup is a tool intended to efficiently back up a directory to a set of size-limited media like CD-Rs or DVD-Rs. It's goal is to distribute the contents of a directory to a set of media while using the space available on these media as best as possible, minimizing the number of media required for a backup. To do this, BinBackup uses a bin packing algorithm to decide how to partition the contents of a directory and where to put them.
Bind DLZ on Rails is a Web-based user interface for managing BIND with the bind-dlz extensions on a MySQL 5.0 backend. BIND is a DNS server, and the bind-dlz extensions enhance BIND with support for database backeneds. This simplifies the management of thousands of zones and provides added redundancy (by way of database replication).
