JBoss is an Open Source, standards-compliant, Enterprise JavaBeans application server implemented in pure Java. JBoss provides JBossServer, the basic EJB container and JMX infrastructure, JBossMQ for JMS messaging, JBossMail for mail, JBossTX for JTA/JTS transactions, JBossSX for JAAS based security, JBossCX for JCA connectivity, and JBossCMP for CMP persistence. It integrates with Tomcat Servlet/JSP container and Jetty Web server/servlet container, and enables you to mix and match these components through JMX by replacing any component you wish with a JMX-compliant implementation for the same APIs. The goal is to provide a full J2EE stack in the Free/Open Source software world.
leJOS is a Java-based replacement firmware (OS) for LEGO Mindstorms programmable bricks, including RCX and NXT. It supports threads, exceptions, synchronization, floating point arithmetic, strings, and so on, but there is no garbage collection yet. It is also designed to be portable to other small devices.
OpenThinClient is a thin client solution consisting of a Linux-based operating system along with a comprehensive Java-based management GUI and server component. It is intended for environments where a medium to large number of thin clients must be supported and managed efficiently.
Thinux is a thin-client server on a live CD. It boots a network of diskless computers to automatically start an application such as a Web browser. Each thin client machine acts as a cluster node to share its processing and memory resources with each other to take the load off the server. It is a turnkey solution that does not change nor rely on your existing systems to run. By booting from a removable CD, it does not lock-in the user so it is convenient to test. It is ideal for any organizations that require large deployment of software automatically and cost effectively.
Systemtap is a GUI to assist in the development of Systemtap scripts and to graph the return values of those scripts. It is intended to ease the use of the Systemtap tool for Linux. It is both an IDE for the scripting language and a data visualization and analysis tool. The GUI is targeted at system administrators who want to get information out of their system using Systemtap, as well as developers who wish to write new scripts. It is an Eclipse-based application.
Fireflier is a firewall tool which is built on top of the iptables framework. It allows you to create rules based on single incoming network packets or to simply allow/deny single packets to pass. It features a client-server approach for administering from another PC, SSL connection between client and server, rules with timeouts (rules are deleted after some time or when fireflier-server shuts down), and filtering based on applications.
Sirid is a Web-based tool for managing software projects. The main features of Sirid are assigning tasks between the personnel, reporting bugs, managing specifications, and recording feature requests. The program also sends notifications of new bugs and tasks to people who have been set responsible for them, and notifies the responsible people when the deadline of some bug or task is approaching. It features graphical presentations for tracking the progress of your project. Sirid keeps you informed of the status of each of your projects, and allows you to take action if difficulties arise.
The DataBean package is a Java library that provides features for mapping a database table to a Java class (databean). The coding of the databean class must conform to a preset pattern so that the instances of the databean classes can perform common database operations without using much of the ugly SQL. DataBean is functional, stable, light-weight, and easy to use. It can make your application much easier to write when dealing with relatively unsophisticated database operations.
