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!)
SyncML is the common language for synchronizing all devices and applications over any network. SyncML leverages eXtensible Markup Language (XML), making SyncML a truly future-proof platform. With SyncML, networked information can be synchronized with any mobile device, and mobile information can be synchronized with any networked applications. SyncML is an open standard.
CD-R/W discs can be written with a technique called packet or incremental writing. This allows transparent and buffer-underrun-free recording for CD recorders that support this method. No more mastering of .iso images; just mount your CD-ROM read/write and copy files directly to it.
Selected Backup uses include and exclude files to provide an efficient method of backing up a list of files and directories. It uses tar and gzip, and has an option to email the attached file to an admin user. It is written in Perl, and has a number of options, including the ability to clean up files older than a certain age.
The CloneIt system was created to copy and essentially clone harddisks of identical PCs through a network. This is a common task when installing server racks or farms or when updating a computer-lab setup where one deals with identical machines. The system software consists of a Linux boot floppy and a ramdisk floppy with minimal system utilities that can perform the task of copying the complete contents of disk devices through a network.
