WavPack is a completely open audio compression format that provides lossless compression, high-quality lossy compression, and a unique hybrid compression mode. The lossless compression ratio depends on the source material, but generally is between 30% and 70%. The hybrid mode provides all the advantages of lossless compression with an additional feature. Instead of creating a single file, this mode creates both a relatively small, high-quality lossy file that can be used all by itself, and a "correction" file that (when combined with the lossy file) provides full lossless restoration. WavPack employs only well known, public domain techniques in its implementation. Methods and algorithms that have ever been patented are specifically avoided. This ensures that WavPack encoders and decoders will remain open and royalty-free.
Wayland is a protocol for a compositor to talk to its clients, as well as a C library implementation of that protocol. The compositor can be a standalone display server running on Linux kernel modesetting and evdev input devices, an X application, or a wayland client itself. The clients can be traditional applications, X servers (rootless or fullscreen), or other display servers.
WBL is a really simple tool that can be used in a .qmail file for managing a white/black list of email addresses. It serves as a pre-filter to allow known-good friends and associates bypass the usual gauntlet of filters. Note that WBL is not intended to be a spam filter, it is simply an easy-to-use whitelist/blacklist management tool that serves to keep email that you really want to see out of your normal filters.
wchat is a telnet based Chat Server written in C. It is designed to use minimal CPU and memory resources, and to be a modular high-level code base. What this means is that all low-level functions are written in separate libraries which wchat uses, allowing any additions or changes to the functionality of the chat to be very simple and straightforward. wchat is an extremely stable and solid base from which to build a chat environment. wchat is not a web-chat, but is commonly connected to via standard mud clients.
wcswizard is a plug-in for IBM Rational Application Developer which contains a wizard that creates the skeleton projects that make up a server-side collaborative component for IBM Workplace Collaboration Services. The wizard provides developers with a skeleton Workplace component which can be immediately deployed to a server.
wctpXml offers C++ developers a class library to support generating WCTP requests, and parsing WCTP responses expressed in XML. Building wctpXml creates a static library appropriate for your environment. The library provides you with a set of classes, wctpXmlXXXX, that encapsulate the operations supported in WCTP Version 1.1.
