INSERT (the Inside Security Rescue Toolkit) aims to be a multi-functional, multi-purpose disaster recovery and network analysis system. It boots from a credit card-sized CD-ROM and is basically a stripped-down version of Knoppix. It features good hardware detection, fluxbox, emelfm, links-hacked, ssh, tcpdump, nmap, chntpwd, and much more. It provides full read-write support for NTFS partitions (using ntfs-3g), and the ClamAV virus scanner (including a fairly recent signature database and a GUI). It provides partition handling with gParted and also has a network boot facility.
Invicta is an open-source build management tool. Using simple project definition files, it generates powerful build scripts (Apache ANTs) while hiding their complexity. Furthermore, Invicta is a modular framework that allows advanced developers add their own customized types of components, which means writing once ANT code that can later be used by all developers in their project or company simply by specifying the new type name.
Japt-Proxy is a fast and reliable caching proxy for Debian's APT system. It is intended for environments where several Debian systems have to be kept up-to-date and downloading the same files over and over again from the Debian mirrors is undesirable. Even with high volume internet connections, it can dramatically reduce the time required to install or update Debian on many machines.
JNC (JavaNativeCompiler) is a Java to native compiler. It allows ahead of time compilation of your Java applications. With JNC, you can create real standalone native binaries which will no longer depend on a JRE. This is especially useful when applications have to be deployed to end users. Native applications are easier to deploy since the end user doesn't need to worry about JRE dependency. They are also harder to decompile, and they load more quickly.
