scdbackup is a simplified CD/DVD backup program for Linux. It can back up large amounts of data on one or more media, with no special tools needed for reading the backup. It supports ISO9660 filesystems and afio archives. Its special features are automatic division of data into multiple volumes, verification of write success, incremental backups, a search and restore helper for large ISO9660 backups. CDs get written via cdrecord, wodim, cdrskin, or xorriso. DVDs and BDs get written via growisofs, cdrskin, or xorriso.
Asterisk is a hybrid TDM and packet voice PBX (Private Branch eXchange) and IVR platform with ACD functionality. It acts as middleware between the Internet (IAX, SIP, MGCP, Skinny, H.323), telephony channels (like Zaptel, T1, PRI, E1, FXO, FXS, VoIP, VoFR, ISDN, modems, Internet Phone Jack, etc.), and applications (like voice-mail, conferencing, directories, MP3 players, intercoms, etc.). It has many advanced features such as a codec translation API. The base distribution includes several channel backends, as well as applications. However, the beauty of Asterisk is its ability to be extended using its APIs, dynamic module loader, and AGI scripting interface. End users can even write their own applications that run on the system in C or any scripting language of their choice.

Melys is a MIDI sequencer application for ALSA. It records, plays back, and saves to a MIDI file or to an XML-based format. There is a track view where you can arrange parts using drag-and-drop and a piano-roll view where the same can be done with notes. There is also a graphical tempo view where the tempo of the song can be changed. Multiple files can be open at once, and notes can be dragged between them. It is written in C and uses the GNOME/Gtk+ widget sets.
TinyCOBOL is an effort to bring a free COBOL compiler to Linux. It generates GNU assembler for the i386 Linux platform. A executable binary is then created using the GNU assembler and linker. The project is approaching the first beta release with many statements already implemented.
