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.
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.
nss-pam-ldapd is a Name Service Switch module and Pluggable Authentication Module using an LDAP server. It allows your LDAP server to provide user account, group, host name, alias, netgroup, and almost any other information that you would normally get from /etc flat files or NIS, and allows you to do authentication to an LDAP server.
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.
oRTP is a library implementing the Real-time Transport Protocol (RFC3550), written in C. It is easy to use and provides a packet scheduler for sending and receiving packets on time, adaptive jitter compensation, automatic sending of RTCP compound packets, and the RTCP parser API. It works with IPv6.
MQ4CPP, or "Message Queuing for C++", is an implementation of an enterprise messaging system, also referred to as message-oriented middleware (MOM). It enables C++ application threads to communicate with other threads locally or remotely through the exchange of messages. A message is a request, report, and/or event that contains information needed to coordinate communication between different applications. MQ4CPP implements direct/indirect messaging, unsolicited messaging, request/reply, conversation, publish/subscribe, store & forward, and broadcast. It supports multithreading, application clustering (failover and session replication), and encryption. MQ4CPP also includes a distributed lock manager, a file transfer manager, and a distributed memory channel.
Embedded HTTP Server (EHS) is a C++ class which can be inherited from to give HTTP server functionality to any class or application. It supports form data via POST or GET, setting and reading cookies, and uploads via multi-part form attachments. It is useful for adding Web-based administration or statistics to any C++ program. It also supports HTTPS for doing secure transactions.
nss-mdns is a plugin for the GNU Name Service Switch (NSS) functionality of the GNU C Library (glibc) which provides host name resolution via Multicast DNS (a.k.a. Zeroconf, a.k.a. Apple Rendezvous, a.k.a Apple Bonjour). This effectively allows name resolution by common Unix/Linux programs in the ad-hoc mDNS domain .local.
