Free Basics
Internet.org is a partnership between social networking services company Facebook and six companies (Samsung, Ericsson, MediaTek, Opera Software, Nokia and Qualcomm) that plans to bring affordable access to selected Internet services to less developed countries by increasing efficiency, and facilitating the development of new business models around the provision of Internet access. The app delivering these services was renamed Free Basics in September 2015. As of November 2016, 40 million people are using internet.org. It has been criticized for violating net neutrality, and by handpicking internet services that are included, for discriminating against companies not in the list, including Facebook's rivals. In February 2016, regulators banned the Free Basics service in India based on "Prohibition of Discriminatory Tariffs for Data Services Regulations". The Telecom Regulatory Authority of India (TRAI) accused Facebook of failing to pass on the four questions in the regulator's consultation paper and also blocking access to TRAI's designated email for feedback on Free Basics. On February 11, 2016, Facebook withdrew the Free Basics platform from India.

Boot Camp
Boot Camp Assistant is a multi boot utility included with Apple Inc.'s macOS (previously Mac OS X / OS X) that assists users in installing Microsoft Windows operating systems on Intel-based Macintosh computers. The utility guides users through non-destructive disk partitioning (including resizing of an existing HFS+ or APFS partition, if necessary) of their hard disk drive or solid-state drive and installation of Windows device drivers for the Apple hardware. The utility also installs a Windows Control Panel applet for selecting the default boot operating system. Initially introduced as an unsupported beta for Mac OS X 10.4 Tiger, the utility was first introduced with Mac OS X 10.5 Leopard and has been included in subsequent versions of the operating system ever since. Previous versions of Boot Camp supported Windows XP and Windows Vista. Boot Camp 4.0 for Mac OS X 10.6 Snow Leopard version 10.6.6 up to Mac OS X 10.8 Mountain Lion version 10.8.2 only supported Windows 7. However, with the release of Boot Camp 5.0 for Mac OS X 10.8 Mountain Lion in version 10.8.3, only 64-bit versions of Windows 7 and Windows 8 are officially supported. Boot Camp 6.0 added support for 64-bit versions of Windows 10. Boot Camp 6.1, available on macOS 10.12 Sierra and later, will only accept new installations of Windows 7 and later; this requirement was upgraded to requiring Windows 10 for macOS 10.14 Mojave. Boot Camp is currently not available on Apple silicon Macs. Via virtualization, it is possible to run ARM-based Windows 10 and 11 (only Windows Insider builds, as they are the only publicly available ARM builds of Windows) through the QEMU emulator and Parallels Desktop virtualization software, which also allows Linux).

Text Classification Algorithms: A Survey
In recent years, there has been an exponential growth in the number of complex documents and texts that require a deeper understanding of machine learning methods to be able to accurately classify texts in many applications. Many machine learning approaches have achieved surpassing results in natural language processing. The success of these learning algorithms relies on their capacity to understand complex models and non-linear relationships within data. However, finding suitable structures, architectures, and techniques for text classification is a challenge for researchers. In this paper, a brief overview of text classification algorithms is discussed. This overview covers different text feature extractions, dimensionality reduction methods, existing algorithms and techniques, and evaluation methods. Finally, the limitations of each technique and its application in real-world problems are discussed.

Bayonetta
Bayonetta is an action hack and slash video game developed by PlatinumGames and published by Sega. The game was originally released for Xbox 360 and PlayStation 3 in Japan in October 2009, and in North America and Europe in January 2010. The game was later released on the Wii U alongside its sequel, Bayonetta 2, releasing in September 2014 in Japan and worldwide the following month - the two games were later released worldwide on the Nintendo Switch in February 2018. An enhanced port for Windows was released in April 2017 with 4K support. A remastered version of Bayonetta as well as another PlatinumGames title, Vanquish, was released for PlayStation 4 and Xbox One on February 18, 2020, as part of a compilation to celebrate the 10th anniversary of the game. Bayonetta takes place in Vigrid, a fictional city in Europe. The game stars the eponymous character, a witch who is capable of shapeshifting and using various firearms. She possesses magical attacks, and she can use her hair to summon demons to dispatch her foes. It features a rating system, which gives players a grade based on their performance, and a combat system that is similar to the Devil May Cry series. Development of the game was started in January 2007, with Hideki Kamiya being the game's director. According to Kamiya, the game was completely original, though he drew some inspirations from Scandinavian mythology, and played Devil May Cry 4 for reference. The game's theme is "sexiness" and "partial nudity", and that the characters were designed to be "fashionable". Kamiya and artist Mari Shimazaki spent more than a year to create Bayonetta's design. Several demos were released for the game prior to its launch. Bayonetta was the third project released by PlatinumGames, which was founded by former Clover Studio employees. Upon release, the game received generally positive reviews. The game was praised for its combat, presentation and soundtrack, but drew criticism for its story and quick time events. Bayonetta was nominated for and won several end-of-the-year accolades, and had sold over a million units worldwide by 2010. An anime film adaptation of the game by Gonzo, titled Bayonetta: Bloody Fate, was released in Japan in November 2013. A third game, Bayonetta 3, is in development for the Switch.

Altitude (Triangle)
In geometry, an altitude of a triangle is a line segment through a vertex and perpendicular to (i.e., forming a right angle with) a line containing the base (the side opposite the vertex). This line containing the opposite side is called the extended base of the altitude. The intersection of the extended base and the altitude is called the foot of the altitude. The length of the altitude, often simply called "the altitude", is the distance between the extended base and the vertex. The process of drawing the altitude from the vertex to the foot is known as dropping the altitude at that vertex. It is a special case of orthogonal projection. Altitudes can be used in the computation of the area of a triangle: one half of the product of an altitude's length and its base's length equals the triangle's area. Thus, the longest altitude is perpendicular to the shortest side of the triangle. The altitudes are also related to the sides of the triangle through the trigonometric functions. In an isosceles triangle (a triangle with two congruent sides), the altitude having the incongruent side as its base will have the midpoint of that side as its foot. Also the altitude having the incongruent side as its base will be the angle bisector of the vertex angle. It is common to mark the altitude with the letter h (as in height), often subscripted with the name of the side the altitude is drawn to. In a right triangle, the altitude drawn to the hypotenuse c divides the hypotenuse into two segments of lengths p and q. If we denote the length of the altitude by hc, we then have the relation For acute and right triangles the feet of the altitudes all fall on the triangle's sides (not extended). In an obtuse triangle (one with an obtuse angle), the foot of the altitude to the obtuse-angled vertex falls in the interior of the opposite side, but the feet of the altitudes to the acute-angled vertices fall on the opposite extended side, exterior to the triangle. This is illustrated in the adjacent diagram: in this obtuse triangle, an altitude dropped perpendicularly from the top vertex, which has an acute angle, intersects the extended horizontal side outside the triangle.

Blue in Culture
The colour blue has been important in culture, politics, art and fashion since ancient times. Blue was used in ancient Egypt for jewellery and ornament. In the Renaissance, blue pigments were prized for paintings and fine blue and white porcelain. in the Middle Ages, deep rich blues made with cobalt were used in stained glass windows. In the 19th century, the colour was often used for military uniforms and fashion. As the colour that most symbolized harmony, blue was chosen as the colour of the flags of the United Nations and the European Union. Surveys in the US and Europe show that blue is the colour most commonly associated with harmony, faithfulness, confidence, distance, infinity, the imagination, cold, and occasionally with sadness. In US and European public opinion polls it is the most popular colour, chosen by almost half of both men and women as their favourite colour. The same surveys also showed that blue was the colour most associated with the masculine, just ahead of black, and was also the colour most associated with intelligence, knowledge, calm, and concentration.

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.

Application Programming Interface
Template:Hatnote group An application programming interface (API) is a computing interface which defines interactions between multiple software intermediaries. It defines the kinds of calls or requests that can be made, how to make them, the data formats that should be used, the conventions to follow, etc. It can also provide extension mechanisms so that users can extend existing functionality in various ways and to varying degrees. An API can be entirely custom, specific to a component, or it can be designed based on an industry standard to ensure interoperability. Through information hiding, APIs enable modular programming, which allows users to use the interface independently of the implementation.

Power systems stability with IBGs
Electrical power system stability is of upmost importance for a secure and reliable supply of electrical energy to residential, commercial and industrial premises. Voltage stability of microgrids, as new components of a power system, is an emerging research area within the concept of power system stability. The main purpose of developing microgrids is to facilitate the integration of renewable energy sources into the power grid. Renewable energy sources are normally connected to the grid via power electronic inverters. As various types of renewable energy sources are increasingly connected to the electrical power grid, power systems of the near future will have more inverter-based generators (IBGs) instead of synchronous generators (SGs). Since IBGs have significant differences in their characteristics compared to SGs , particularly with regard to their inertia and capability to provide reactive power, their impacts on the system dynamics are different compared to SGs. A comprehensive review on voltage stability of power systems with the inclusion of inverter-based generators is presented.

Effect of Surjection on Inheritance
Consider a biological evolutionary process.  We assume some (non-empty) finite set of offspring.  Assume each offspring is assigned as coming from a single set of parents in the previous generation.  There may be more than one offspring from each of set of parents.  This form of mathematical arrangement is called a surjection.   We have briefly described the mechanics of genetics; but we have also described much of mathematical anthropology.   The finding that a process is a surjection does not just describe the algebra, it also predicts important results.  If we have found an inheritance process is a surjection, then each of the offspring is unique, but all of the acts of parental pairs must occur through identical (including isomorphic) means of reproduction; in fact here they require mathematical groups.  We demonstrate from published surveys that all offspring are unique.  Mathematical groups occur in both applications, determining the choices behind parental actions.  The surjection requirements are met in genetics because the mathematics are determined by the mathematical groups determined by quantum mechanics.  In culture theory, similar (and in some cases, isomorphic) groups occur.  Quantum mechanics is usually discussed for very small objects with incredibly short process intervals.  Here, the intervals of reproduction are observable within normal human perception, and for human cultural systems require decades of time for one generation system to be replaced by another.  In genetics, counting of the number of offspring from each pair of “parents” is the actual number of offspring surviving from each pair to reproduce.  Each human culture has its own means of assigning offspring to parental pairs, which may include their surviving genetic offspring, but also may use culturally designated devices such as adoption.  Since surjection also requires that distributions might be forecasted using the Stirling Number of the Second Kind, that result allows culture theory to predict the numbers of offspring per assigned couple, and the percentage of adults engaging in that reproduction.
