The snow package provides support for simple parallel computing on a network of workstations using R. A master R process calls makeCluster to start a cluster of worker processes; the master process then uses functions such as clusterCall and clusterApply to execute R code on the worker processes and collect and return the results on the master. This framework supports many forms of "embarrassingly parallel" computations. Snow can use one of four communications mechanisms: sockets, PVM, MPI, or NetWorkSpaces (NWS). NWS support was provided by Steve Weston. PVM clusters use the rpvm package; MPI clusters use package Rmpi; NWS clusters use package nws. If pvm is used, then pvm must be started, either using a pvm console (e.g the pvm text console or the graphical xpvm console, both available with pvm) or from R using functions provided by rpvm. Similarly, LAM-MPI must be started, e.g. using lamboot, for MPI clusters that use Rmpi and LAM-MPI. If NWS is used, the NetWorkSpaces server must be running. SOCK clusters are the easiest approach for using snow on a single multi-core computer as they require no additional software.

C++ wrapper for Atk.

The GNOME On-Screen Keyboard (GOK) is an accessibility interface that gives you control of your system without needing a keyboard. The GOK makes available a hierarchical button system that enables keyboardless entry of common accelerators, and contains a clickable keyboard that sports suggested autocompletion of many common words, and even some commands. The GOK will provide an alternative interface to common commands and functions within applications that utilize the AT SPI. The GOK is designed to be usable by many alternative input methods, i.e. not a common keyboard and mouse combination.

KTTS -- KDE Text-to-Speech -- is a subsystem within the KDE desktop for conversion of text to audible speech. KTTS is currently under development and aims to become the standard subsystem for all KDE applications to provide speech output.

Kaccessible implements a QAccessibleBridgePlugin to provide accessibility services like focus tracking and a screenreader.

This port contains a set of KDE-based applications for accessibility needs.

Accessibility Toolkit, Linux/i386 binary from the Web page: The ATK library provides a set of interfaces for accessibility. By supporting the ATK interfaces, an application or toolkit can be used with such tools as screen readers, magnifiers, and alternative input devices.

Redshift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night.

YASR ("Yet Another Screen Reader") is an attempt at a lightweight, portable screen reader. It works by opening a shell in a pty and intercepting all user input/output, maintaining a window of what should be on the screen by looking at the codes and text sent to the screen. It thus uses no Linuxisms such as /dev/vcsa0 and does not necessarily need to be setuid root (the only requirement being that the user be able to access the tts device).
