UDP Test is a simple UDP server and client bundled into a single script. It is designed to be used as a network testing tool, and it detects packet loss and corruption. UDP is a lossy network transport in that UDP packets may be dropped if there is not enough capacity to send them. UDP is typically used in real-time scenarios such as voice and video chat. udptest.rb is designed to be as simple as possible. It bounces small packets from the client to the server and back again. If the packet checksum is incorrect at any point, the script exits with an error. This type of script is designed to detect faulty hardware and errors in configuration, as well as network performance.
PostRemoteLog is a tool that allows you to send information across the network to a centralized location. Three methods are currently supported: XMLRPC, Email, and Growl. It is generally aimed at system administrators who want to keep track of information such as backup post-run scripts, network monitoring scripts, UPS information, service outages, power on/off, unexpected restarts, etc. PostRemoteLog is designed to be used in other scripts. Captured data can be analyzed and aggregated as needed.

omnisode.rb, preodein.rb, and preindent.rb are a set of Ruby programs to generate a program to use long Taylor series to solve systems of ordinary differential equations. It generates code to solve the equations in either C, C++, Ruby, Maple, or Maxima. Using the Taylor series, estimates are made of the location of poles.
Metasploit Express is security software for security professionals in enterprises and government agencies who need to carry out penetration tests against their systems quickly and easily. It adds a graphical user interface to the Metasploit Framework, the de-facto leader in pentesting tools, and automates many of the tasks that otherwise require custom scripting, such as smart brute forcing, evidence collection, and reporting.
