The Advanced Linux Sound Architecture is composed of several parts. The first is a fully modularized sound driver which supports module autoloading, devfs, isapnp autoconfiguration, and gives complete access to analog audio, digital audio, control, mixer, synthesizer, DSP, MIDI, and timer components of audio hardware. It also includes a fully-featured kernel-level sequencer, a full compatibility layer for OSS/Free applications, an object-oriented C library which covers and enhances the ALSA kernel driver functionality for applications (client/server, plugins, PCM sharing/multiplexing, PCM metering, etc.), an interactive configuration program for the driver, and some simple utilities for basic management.
The DECnet for Linux project aims to provide the kernel-level socket layer and a set of applications to allow Linux systems to participate in a DECnet phase IV network. It currently has an application library (suitable for building DECnet functionality into X11R6), file and terminal access.
GNet is a network library. It is object-oriented, written in C, and built upon GLib. It is intended to be easy to use and port. It supports abstract Internet addresses, TCP, UDP, IP Multicast, IPv6, asynchronous DNS lookups, SHA, MD5, Base64, URIs, and SOCKS. It comes with documentation and examples.
Gumshoe is a program that connects to multiple file sharing services, allowing one to search and download from any of them simultaneously with a consistent interface. Currently only Napster and Gnutella are supported. A plugin system makes it easy to add more. A console UI is implemented, graphical and possibly HTML/HTTP interfaces will come later.
JDxpc is a reimplementation of dxpc (the Differential X Protocol Compressor) in pure Java. It is an X protocol compressor designed to improve the speed of X applications run over low-bandwidth links (such as dialup PPP connections). JDxpc encrypts the compressed data stream in SSL.
For users on Linux and Unix, KDE offers a full suite of user workspace applications which allow interaction with these operating systems in a modern, graphical user interface. This includes Plasma Desktop, KDE's innovative and powerful desktop interface. Other workspace applications are included to aid with system configuration, running programs, or interacting with hardware devices. While the fully integrated KDE Workspaces are only available on Linux and Unix, some of these features are available on other platforms. In addition to the workspace, KDE produces a number of key applications such as the Konqueror Web browser, Dolphin file manager, and Kontact, the comprehensive personal information management suite. The list of applications includes many others, including those for education, multimedia, office productivity, networking, games, and much more. Most applications are available on all platforms supported by the KDE Development. KDE also brings to the forefront many innovations for application developers. An entire infrastructure has been designed and implemented to help programmers create robust and comprehensive applications in the most efficient manner, eliminating the complexity and tediousness of creating highly functional applications.
Heartbeat is a full-function high-availability system for Linux and other POSIX-like OSes. It monitors services and restarts them on errors. When managing a cluster (more than 1 machine), it will also monitor the members of the cluster and begin recovery of lost services in less than a second. It runs over serial ports and UDP broadcast/multicast, as well as OpenAIS multicast. It is easily adapted to different interconnect media and protocols. When used in a cluster, it can operate using shared disks, data replication, or no data sharing. Versions starting with 2.0 are comparable to any commercial HA package, providing resource monitoring, larger clusters, and detailed dependency information.
nss_ldap is an RFC 2307-compliant set of C library extensions which allows X.500 and LDAP directory servers to be used as a primary source of aliases, ethers, groups, hosts, networks, protocol, users, RPCs, services and shadow passwords (instead of or in addition to using flat files or NIS).
