Celerity

Celerity is a JRuby wrapper around HtmlUnit – a headless Java browser with JavaScript support. It provides a simple API for programmatic navigation through web applications. Celerity aims at being API compatible with Watir.

Features

• Fast - No time-consuming GUI rendering or unessential downloads
• Easy to use - Simple API
• JavaScript support
• Scalable - Java threads lets you run tests in parallel
• Portable - Cross-platform thanks to the JVM
• Unintrusive - No browser window interrupting your workflow (runs in background)

Watir. Automated testing that doesn’t hurt

Watir, pronounced water, is an open-source (BSD) library for automating web browsers. It allows you to write tests that are easy to read and maintain. It is simple and flexible.
Watir drives browsers the same way people do. It clicks links, fills in forms, presses buttons. Watir also checks results, such as whether expected text appears on the page.
Watir is a family of Ruby libraries but it supports your app no matter what technology it is developed in. They support Internet Explorer on Windows, Firefox on Windows, Mac and Linux, Safari on Mac, Chrome on Windows and Flash testing with Firefox.
Like other programming languages, Ruby gives you the power to connect to databases, read data files and spreadsheets, export XML, and structure your code as reusable libraries. Unlike other programming languages, Ruby is concise and often a joy to read.

BackgrounDRb

BackgrounDRb is a Ruby job server and scheduler. Its main intent is to be used with Ruby on Rails applications for offloading long-running tasks. Since a Rails application blocks while serving a request it is best to move long-running tasks off into a background process that is divorced from http request/response cycle.

Enhance Tables Using One Of 30 Functional jQuery Plugins

Classic ways of using simple html tables are long gone – of course you can still use them, but you will never get such functionality and flexibility with HTML as you can get using special jQuery plugins to do the job.
Never tables have been so dynamic and users now can specify and filter all the sections they want, you just need to find right plugin for specific project.

Unicorn

Unicorn is an HTTP server for Ruby, similar to Mongrel or Thin. It uses Mongrel’s Ragel HTTP parser but has a dramatically different architecture and philosophy.
In the classic setup you have nginx sending requests to a pool of mongrels using a smart balancer or a simple round robin.
Eventually you want better visibility and reliability out of your load balancing situation, so you throw haproxy into the mix:

RabbitMQ

RabbitMQ is based on a proven platform, offering exceptionally high reliability, availability and scalability along with good throughput and latency performance that is predictable and consistent. It has a compact, easily maintainable code base allowing rapid customisation and hot deployment. There are extensive facilities for management, monitoring, control and debugging and it is supported by a full range of commercial support services and an active community developing packages that extend the core system.
