Libgta implements the Generic Tagged Arrays (GTA) file format. GTAs can store any kind of data in multidimensional arrays, optionally with simple tags to store rich metadata. GTAs are streamable and support mupltiple compression methods. Uncompressed GTAs allow easy out-of-core data access for very large arrays.
GNU xorriso creates, loads, manipulates, and writes ISO 9660 filesystem images with Rock Ridge extensions. Files can be copied in and out. The session results get written to optical media or to filesystem objects. Rather than needing external tools for ISO 9660 production and CD/DVD/BD burning, it is a static compilation of libburnia-project.org. Thus GNU xorriso depends only on fundamental operating system facilities.
Super Grub Disk is a bootable floppy or CDROM that is oriented towards system rescue, specifically for repairing the booting process. Super Grub Disk is simply a Grub Disk with a lot of useful menus. It can activate partitions, boot partitions, boot MBRs, boot your former OS (Linux or another one) by loading menu.lst from your hard disk, automatically restore Grub on your MBR, swap hard disks in the BIOS, and boot from any available disk device. It has multi-language support, and allows you to change the keyboard layout of your shell.
GNU libmicrohttpd is a small C library for embedding HTTP server functionality into other applications. It is reentrant, fast, supports HTTP 1.1, and permits listening on multiple ports. The API is simple and still powerful enough to allow programmers to use the entire HTTP feature set. SSL/TLS support is available as an option.
g7ctrl is a daemon and a command shell that are used together with the Xtreme GM7 GPS tracker to help simplify its management and to make it possible to monitor alerts sent by the tracker. It is designed to run in the background and can be used to both receive location updates from a remote tracker and configure a tracker over USB. All received events are stored in a database and can be exported to GPX, KML, and CSV, with distances calculated. It can also execute action scripts upon receiving specific events or generate mail notifications. Extensive reference documentation (HTML and PDF) and Unix man pages are provided.
Tomb is a system to make strong encryption easy for everyday use. A tomb is like a locked folder that can be safely transported and hidden in a filesystem. Its keys can be kept separate; for example, you can keep the tomb on your computer and its key on a USB stick. Tomb is written in code that is easy to review and links shared components: it consists of a ZShell script and desktop integration apps; it uses standard GNU tools and the cryptographic API of the Linux kernel (dm-crypt) via cryptsetup.
xllmnrd is an IPv6 LLMNR responder daemon (primarily for GNU/Linux operating systems). It allows Microsoft Windows clients to get the IPv6 address of a server on the same local network without any DNS configuration and effectively complements IPv4-only NetBIOS name resolution provided by Samba.
Jaro Mail is an integrated suite of interoperable tools for GNU/Linux and Apple/OS X to manage email communication in a private way, without relying on online services (in fact, encouraging users to store email locally). It mainly features a system for mailinglist filtering, address-book integrated whitelisting, and long-term email storage and archiving with functions for fast search and usage statistics. It makes internal use of customized versions of popular Unix tools like Mutt, Fetchmail, Procmail, Mairix, and Msmtp.
