Byzantine Fault Tolerance
Byzantine fault tolerance (BFT) is the dependability of a fault-tolerant computer system, particularly distributed computing systems, where components may fail and there is imperfect information on whether a component has failed. In a "Byzantine failure", a component such as a server can inconsistently appear both failed and functioning to failure-detection systems, presenting different symptoms to different observers. It is difficult for the other components to declare it failed and shut it out of the network, because they need to first reach a consensus regarding which component has failed in the first place. The term is derived from the Byzantine Generals' Problem, where actors must agree on a concerted strategy to avoid catastrophic system failure, but some of the actors are unreliable. Byzantine fault tolerance has been also referred to with the phrases interactive consistency or source congruency, error avalanche, Byzantine agreement problem, Byzantine generals problem, and Byzantine failure.

Prince of Wales's Feathers
Template:Infobox Coat of arms The Prince of Wales's feathers is the heraldic badge of the Prince of Wales. It consists of three white ostrich feathers emerging from a gold coronet.

List of Fictional Colors
Fictional colors are the imaginary perceptions of colors that do not exist for humans. They may include colors as perceived by fictional aliens, or colors that are imagined to be perceptible by humans under imaginary circumstances, based on real or imaginary electromagnetic radiation or imaginary alternate forms of radiation.

Monoculture (Computer Science)
In computer science, a monoculture is a community of computers that all run identical software. All the computer systems in the community thus have the same vulnerabilities, and, like agricultural monocultures, are subject to catastrophic failure in the event of a successful attack.

Radiance
Radiance is a suite of tools for performing lighting simulation originally written by Greg Ward. It includes a renderer as well as many other tools for measuring the simulated light levels. It uses ray tracing to perform all lighting calculations, accelerated by the use of an octree data structure. It pioneered the concept of high-dynamic-range imaging, where light levels are (theoretically) open-ended values instead of a decimal proportion of a maximum (e.g. 0.0 to 1.0) or integer fraction of a maximum (0 to 255 / 255). It also implements global illumination using the Monte Carlo method to sample light falling on a point. Greg Ward started developing Radiance in 1985 while at Lawrence Berkeley National Laboratory. The source code was distributed under a license forbidding further redistribution. In January 2002 Radiance 3.4 was relicensed under a less restrictive license. One study found Radiance to be the most generally useful software package for architectural lighting simulation. The study also noted that Radiance often serves as the underlying simulation engine for many other packages.

IcedTea
IcedTea is a build and integration project for OpenJDK launched by Red Hat in June 2007. IcedTea also includes some addon libraries: IcedTea-Web is a free software implementation of Java Web Start and the Java web browser applet plugin. IcedTea-Sound is a collection of plugins for the Java sound subsystem, including the PulseAudio provider which used to be included with IcedTea. The Free Software Foundation recommends that all Java programmers use IcedTea as their development environment. Historically, the initial goal of the IcedTea project was to make the OpenJDK software, which Sun Microsystems released as free software in 2007, usable without requiring any proprietary software, and hence make it possible to add OpenJDK to Fedora and other Linux distributions that insist on free software. This goal was met, and a version of IcedTea based on OpenJDK was packaged with Fedora 8 in November 2007. April 2008 saw the first release of a new variant, IcedTea6, which is based on Sun's build drops of OpenJDK6, a fork of the OpenJDK with the goal of being compatible with the existing JDK6. This was released in Ubuntu and Fedora in May 2008. The IcedTea package in these distributions has been renamed to OpenJDK using the OpenJDK trademark notice. In June 2008, the Fedora build passed Sun's rigorous TCK testing on x86 and x86-64. IcedTea 2, the first version based on OpenJDK 7, was released in October 2011. IcedTea 3, the first version based on OpenJDK 8, was released in April 2016. Support for IcedTea 1 was dropped in January 2017.
