JSX serializes Java objects to XML. You can persist objects, evolve them, and send them over the network and between applications. Your object data becomes human-readable and human-writable. You can test it, search it, profile it, audit it, and edit it with ordinary text and XML tools. JSX handles all POJOs and also all classes that require Java's own object serialization.
SuperRescue is a single very large bootable system-on-a-disk. It's based on the observation that the vast majority of systems allow you to do so much more than the minimal system. Therefore, it isn't for everything, but for most desktop systems, it provides a much nicer rescue environment than your average rescue floppy. It requires an i386 PC with 24 MB of RAM and a bootable CD-ROM. PCMCIA support is implemented but somewhat limited. It is based on RedHat 7. (Version 1 is based on RedHat 6.)
SystemImager automates the installation of Linux to masses of similar machines. Software distribution, configuration, and operating system updates are made easy, including updates from one Linux release to another. It can also be used for content distribution on Web servers. It is most useful in environments with large numbers of identical machines. Some typical environments include Internet server farms, high performance clusters, computer labs, and corporate desktop environments where all workstations have the same basic hardware configuration.
VDMFEC implements Block ECC using a Forward Error Correction (FEC) code based on Vandermonde (VDM) matrices in GF(2^8) due to Luigi Rizzo. Given the FEC parameters K and N, with N greater than K, N blocks are written for every K input blocks in such a way that any K blocks are sufficient to reconstruct the data. That is, up to N - K blocks out of every group of N blocks may be lost without loss of data. VDMFEC's primary application is intended to be in recovering data from unreliable media such as diskettes. With appropriate parameters, files may be recovered even with many read errors. (Note that you must write the data to the diskette using this program in order to be able to recover the data later!)
Channel16 is graphical tool that allows users to browse the content of deleted files in an ext2 filesystem interactively, and to recover them into new files. The application also provides a search and rescue operation. This allows the user to input some exact text from the deleted file, which the program uses to search through all deleted inodes. Channel16 uses the low-level methods provided by e2fsprogs. The front end is implemented with Java Swing, and Java Native Interface (JNI) is used to bridge between Java and the ext2fs operations.
