diet libc contains the system call wrappers and the most commonly-used functions you expect from a libc. It can be used to create small, statically-linked binaries under x86, AMD64, SPARC, SPARC64, PPC, PPC64, ARM, MIPS, MIPS64, PA-RISC, S/390, S/390x (64-bit S/390), and Alpha-Linux.
DigitalDJ is an SQL-based MP3-player frontend designed for people who want to create an MP3 version of their CD collection. It is designed to work with the Grip ripping/encoding application (but can be used separately). When Grip encodes MP3 files, it will place all of the song information into an SQL database. DigitalDJ can then use this information to create playlists based on a number of criteria.
DigiTemp uses a simple serial port adapter to read temperatures from the Dallas Semiconductor 1-Wire DS1820 digital temperature sensors. It supports the DS9097-U adapter, supports DS2409 based 1-Wire hubs, and features a 1-Wire walk that will display all devices on the LAN, not just temperature sensors.
DINO is a realtime visualization program for structural biology data, including protein and nucleic-acid coordinates, molecular surfaces, electrostatic potentials, electron densities, surface topographs (from AFM), and MD trajectories. It supports PNG, PostScript and POVray (3.1g and megapov) output. Supported platforms are Linux/i386, Linux/PPC, IRIX, Sun, OSF1, and MacOS X.
dircproxy is an IRC proxy server ("bouncer") designed for people who use IRC from lots of different workstations or clients, but wish to remain connected and see what they missed while they were away. You connect to IRC through dircproxy, and it keeps you connected to the server, even after you detach your client from it. While you're detached, it logs channel and private messages as well as important events, and when you reattach it'll download those logs to you using ordinary IRC protocol.
distributed.net is a loosely knit group of computer users from all of the world that is taking up challenges requiring lots of computing power (most notably the RC5, DES, and OGR cracking contests). It is simple to participate in the challenges by downloading and running their client software (which uses idle CPU time to complete its tasks).
divine will use ARP requests to look for hosts that are always up in the networks that you frequently use your laptop in and then set the IP configuration including /etc/resolv.conf and write proxy settings in /etc/proxy. A perl script to edit your netscape 4 preferences is included. You can also run a custom script for each network to edit /etc/printcap or /etc/issue or whatever you feel like. The ARP method is much quicker than the "ping" method that other solutions use.
