4Sports is an exercise management application. You can use it to analyze your exercises in a number of ways. 4Sports can import data from the Garmin "Forerunner 201/301" devices, and can display some information in a table and in a graph (like heart rate over distance). It's also possible to export the tracks (GPS data) into Google Earth, where the track is color-coded according to your heart-rate. The graphs can be exported to SVG files.
6jack is a framework for testing, analyzing, and fuzzing network applications. 6jack runs a command, intercepts calls to common network-related system calls, and passes them through an external filter. A filter can be written in any language supporting the MessagePack serialization library. 6jack is especially useful for writing tests for clients and servers, debugging and reverse engineering protocols, sketching filtering proxies, and fuzzing.
Active Record connects business objects and database tables to create a persistable domain model where logic and data is presented in one wrapping. It’s an implementation of the object-relational mapping (ORM) pattern in which an object that wraps a row in a database table or view, encapsulates the database access, and adds domain logic on that data.
The Amahi Home Server is a Linux home server based on Fedora (and later on Ubuntu). Your machine becomes a "Home Digital Assistant" (HDA) after the installation. It provides a growing set of community packaged apps like an iTunes server, UPnP server, calendar server, a wiki, shared network storage, network backups, a printer server, VPN, and a plug-in architecture built on Ruby on Rails.
AntFlow builds upon Apache Ant to provide a new approach to simplifying system automation that uses pipelines of hot folders chained together to perform a given task. Using XML, it associates an automated task such as data transfer, encryption, or XML processing with a directory on the local system. Whenever a file is copied or written into the hot folder, the associated task is executed and the file is moved to the next hot folder in the pipeline for further processing.
Arachno Ruby IDE is a development environment with an Emacs-like editor, an integrated very fast GUI debugger, source code browsing, live syntax checking, a local Apache environment for developing/debugging CGIs and integrated FTP, and a GNU diff frontend. The debugger offers an easy way to debug CGI and ERuby Web applications. It runs on Windows 2000 and XP, SuSE Linux 9.1/9.2, and other 2.6 kernel Linux distributions.
