Ex-tangential Quadrilateral
In Euclidean geometry, an ex-tangential quadrilateral is a convex quadrilateral where the extensions of all four sides are tangent to a circle outside the quadrilateral. It has also been called an exscriptible quadrilateral. The circle is called its excircle, its radius the exradius and its center the excenter (E in the figure). The excenter lies at the intersection of six angle bisectors. These are the internal angle bisectors at two opposite vertex angles, the external angle bisectors (supplementary angle bisectors) at the other two vertex angles, and the external angle bisectors at the angles formed where the extensions of opposite sides intersect (see the figure to the right, where four of these six are dotted line segments). The ex-tangential quadrilateral is closely related to the tangential quadrilateral (where the four sides are tangent to a circle). Another name for an excircle is an escribed circle, but that name has also been used for a circle tangent to one side of a convex quadrilateral and the extensions of the adjacent two sides. In that context all convex quadrilaterals have four escribed circles, but they can at most have one excircle.

Opaque Forest Problem
In computational geometry, the opaque forest problem can be stated as follows: "Given a convex polygon C in the plane, determine the minimal forest T of closed, bounded line segments such that every line through C also intersects T". T is said to be the opaque forest, or barrier of C. C is said to be the coverage of T. While any forest that covers C is a barrier of C, we wish to find the one with shortest length. It may be the case that T is constrained to be strictly interior or exterior to C. In this case, we specifically refer to a barrier as interior or exterior. Otherwise, the barrier is assumed to have no constraints on its location.

Plural Quantification
In mathematics and logic, plural quantification is the theory that an individual variable x may take on plural, as well as singular, values. As well as substituting individual objects such as Alice, the number 1, the tallest building in London etc. for x, we may substitute both Alice and Bob, or all the numbers between 0 and 10, or all the buildings in London over 20 stories. The point of the theory is to give first-order logic the power of set theory, but without any "existential commitment" to such objects as sets. The classic expositions are Boolos 1984 and Lewis 1991.

Babylon
Babylon is a computer dictionary and translation program developed by the Israeli company Babylon Software Ltd. based in the city of Or Yehuda. The company was established in 1997 by the Israeli entrepreneur Amnon Ovadia. Its IPO took place ten years later. It is considered a part of Israel's Download Valley, a cluster of software companies monetizing "free" software downloads through adware. Babylon includes in-house proprietary dictionaries, as well as community-created dictionaries and glossaries. It is a tool used for translation and conversion of currencies, measurements and time, and for obtaining other contextual information. The program also uses a text-to-speech agent, so users hear the proper pronunciation of words and text. Babylon has developed 36 English-based proprietary dictionaries in 21 languages. In 2008–2009, Babylon reported earnings of 50 million NIS through its collaboration with Google. Between 2010 and 2013, Babylon became infamous for demonstrating questionable behavior typical of malware: A Babylon Toolbar bundled with Babylon and other software, has been widely identified as a browser hijacker that is very easy to install inadvertently and unnecessarily difficult to remove. This eventually led to Google terminating its agreement with Babylon Ltd. in 2013.

The King of Fighters: Maximum Impact
KOF: Maximum Impact is a fighting game developed by SNK subsidiary Noise Factory and published by SNK Playmore for the PlayStation 2 in 2004–2005. An enhanced version was released for the Xbox under the title KOF Maximum Impact: Maniax. The King of Fighters: Maximum Impact Regulation "A" was released for Taito Type X2 on July 14, 2007 and for PlayStation 2 on July 26, 2007 and only in Japan. Marketed as a spin-off of SNK's major fighting series The King of Fighters, whence many of its characters originate, KOF: Maximum Impact also contains elements of the Fatal Fury and Art of Fighting series. KOF: Maximum Impact is the first 3D fighter made by SNK since 1990s era's Fatal Fury and lastly, Samurai Shodown for the PlayStation. The game was followed by KOF. While the version released in the U.S. featured an English dub that was met with much derision (with IGN's Jeremy Dunham going so far as to label it "piss poor"), further releases for the Xbox and European PS2 add a choice of English and Japanese language options. The Xbox version also includes an online match mode where matches can be fought between players via Xbox Live.

Eclipse
Eclipse is an integrated development environment (IDE) used in computer programming. It contains a base workspace and an extensible plug-in system for customizing the environment. It is the second-most-popular IDE for Java development, and, until 2016, was the most popular. Eclipse is written mostly in Java and its primary use is for developing Java applications, but it may also be used to develop applications in other programming languages via plug-ins, including Ada, ABAP, C, C++, C#, Clojure, COBOL, D, Erlang, Fortran, Groovy, Haskell, JavaScript, Julia, Lasso, Lua, NATURAL, Perl, PHP, Prolog, Python, R, Ruby (including Ruby on Rails framework), Rust, Scala, and Scheme. It can also be used to develop documents with LaTeX (via a TeXlipse plug-in) and packages for the software Mathematica. Development environments include the Eclipse Java development tools (JDT) for Java and Scala, Eclipse CDT for C/C++, and Eclipse PDT for PHP, among others. The initial codebase originated from IBM VisualAge. The Eclipse software development kit (SDK), which includes the Java development tools, is meant for Java developers. Users can extend its abilities by installing plug-ins written for the Eclipse Platform, such as development toolkits for other programming languages, and can write and contribute their own plug-in modules. Since the introduction of the OSGi implementation (Equinox) in version 3 of Eclipse, plug-ins can be plugged-stopped dynamically and are termed (OSGI) bundles. Eclipse software development kit (SDK) is free and open-source software, released under the terms of the Eclipse Public License, although it is incompatible with the GNU General Public License. It was one of the first IDEs to run under GNU Classpath and it runs without problems under IcedTea.

XTS-400
The XTS-400 is a multilevel secure computer operating system. It is multiuser and multitasking that uses multilevel scheduling in processing data and information. It works in networked environments and supports Gigabit Ethernet and both IPv4 and IPv6. The XTS-400 is a combination of Intel x86 hardware and the Secure Trusted Operating Program (STOP) operating system. XTS-400 was developed by BAE Systems, and originally released as version 6.0 in December 2003. STOP provides high-assurance security and was the first general-purpose operating system with a Common Criteria assurance level rating of EAL5 or above. The XTS-400 can host, and be trusted to separate, multiple, concurrent data sets, users, and networks at different sensitivity levels. The XTS-400 provides both an untrusted environment for normal work and a trusted environment for administrative work and for privileged applications. The untrusted environment is similar to traditional Unix environments. It provides binary compatibility with Linux applications running most Linux commands and tools as well as most Linux applications without the need for recompiling. This untrusted environment includes an X Window System GUI, though all windows on a screen must be at the same sensitivity level. To support the trusted environment and various security features, STOP provides a set of proprietary APIs to applications. In order to develop programs that use these proprietary APIs, a special software development environment (SDE) is needed. The SDE is also needed in order to port some complicated Linux/Unix applications to the XTS-400. A new version of the STOP operating system, STOP 7 has since been introduced, with claims to have improved performance and new features such as RBAC.
