🔗 Internet 🔗 Politics

The alt-right pipeline (also called the alt-right rabbit hole) is a conceptual model regarding internet radicalization toward the alt-right movement. It describes a phenomenon in which consuming provocative right-wing political content, such as antifeminist or anti-SJW ideas, gradually increases exposure to the alt-right or similar far-right politics. It posits that this interaction takes place due to the interconnected nature of political commentators and online communities, allowing members of one audience or community to discover more extreme groups. This process is most commonly associated with and has been documented on the video platform YouTube, is also largely faceted by the method in which algorithms on various social media platforms function through the process recommending content that is similar to what users engage with, but can quickly lead users down rabbit-holes.

Many political movements have been associated with the pipeline concept. The intellectual dark web, libertarianism, the men's rights movement, and the alt-lite movement have all been identified as possibly introducing audiences to alt-right ideas. BreadTube has similarly been identified as introducing audiences to far-left politics, though it has been less effective. Audiences that seek out and are willing to accept extreme content in this fashion typically consist of young men, commonly those that experience significant loneliness and seek belonging or meaning. In an attempt to find community and belonging, message boards that are often proliferated with hard right social commentary, such as 4chan and 8chan, have been well documented in their importance in the radicalization process.

The alt-right pipeline may be a contributing factor to domestic terrorism. Many social media platforms have acknowledged this path of radicalization and have taken measures to prevent it, including the removal of extremist figures and rules against hate speech and misinformation.

🔗 Cryptography 🔗 Cryptography/Computer science

Bacon's cipher or the Baconian cipher is a method of steganographic message encoding devised by Francis Bacon in 1605. A message is concealed in the presentation of text, rather than its content. Bacon cipher is categorized as both a substitution cipher (in plain code) and a concealment cipher (using the two typefaces).

🔗 Languages 🔗 South Africa

Afrikaans is a daughter language of Dutch and—unlike Netherlands Dutch, Belgian Dutch and Surinamese Dutch—a separate standard language rather than a national variety. As an estimated 90 to 95% of Afrikaans vocabulary is ultimately of Dutch origin, there are few lexical differences between the two languages; however, Afrikaans has a considerably more regular morphology, grammar, and spelling.

🔗 Statistics

Extreme learning machines are feedforward neural networks for classification, regression, clustering, sparse approximation, compression and feature learning with a single layer or multiple layers of hidden nodes, where the parameters of hidden nodes (not just the weights connecting inputs to hidden nodes) need not be tuned. These hidden nodes can be randomly assigned and never updated (i.e. they are random projection but with nonlinear transforms), or can be inherited from their ancestors without being changed. In most cases, the output weights of hidden nodes are usually learned in a single step, which essentially amounts to learning a linear model. The name "extreme learning machine" (ELM) was given to such models by its main inventor Guang-Bin Huang.

According to their creators, these models are able to produce good generalization performance and learn thousands of times faster than networks trained using backpropagation. In literature, it also shows that these models can outperform support vector machines (SVM) and SVM provides suboptimal solutions in both classification and regression applications.

🔗 Alternative education

A Sudbury school is a type of school, usually for the K-12 age range, where students have complete responsibility for their own education, and the school is run by a direct democracy in which students and staff are equal citizens. Students use their time however they wish, and learn as a by-product of ordinary experience rather than through coursework. There is no predetermined educational syllabus, prescriptive curriculum or standardized instruction. This is a form of democratic education. Daniel Greenberg, one of the founders of the original Sudbury Model school, writes that the two things that distinguish a Sudbury Model school are that everyone - adults and children - are treated equally and that there is no authority other than that granted by the consent of the governed.

While each Sudbury Model school operates independently and determines their own policies and procedures, they share a common culture. The intended culture within a Sudbury school has been described with such words as freedom, trust, respect, responsibility and democracy.

The name 'Sudbury' originates from the Sudbury Valley School, founded in 1968 in Framingham, Massachusetts, near Sudbury, Massachusetts. Though there is no formal or regulated definition of a Sudbury Model school, there are now more than 60 schools that identify themselves with Sudbury around the world. Some, though not all, include "Sudbury" in their name. These schools operate as independent entities and are not formally associated in any way.

A skeuomorph () is a derivative object that retains nonfunctional ornamental design cues (attributes) from structures that were inherent to the original. Examples include pottery embellished with imitation rivets reminiscent of similar pots made of metal and a software calendar that imitates the appearance of binding on a paper desk calendar.

🔗 Computing

Fog computing or fog networking, also known as fogging, is an architecture that uses edge devices to carry out a substantial amount of computation, storage, and communication locally and routed over the internet backbone.

🔗 Philosophy 🔗 Books 🔗 Philosophy/Philosophy of science 🔗 Science

The Two Cultures is the first part of an influential 1959 Rede Lecture by British scientist and novelist C. P. Snow which were published in book form as The Two Cultures and the Scientific Revolution the same year. Its thesis was that science and the humanities which represented "the intellectual life of the whole of western society" had become split into "two cultures" and that this division was a major handicap to both in solving the world's problems.

🔗 Video games 🔗 Computing

Habitat is a massively multiplayer online role-playing game (MMORPG) developed by LucasArts. It is the first attempt at a large-scale commercial virtual community that was graphic based. Initially created in 1985 by Randy Farmer and Chip Morningstar, the game was made available as a beta test in 1986 by Quantum Link, an online service for the Commodore 64 computer and the corporate progenitor to AOL. Both Farmer and Morningstar were given a First Penguin Award at the 2001 Game Developers Choice Awards for their innovative work on Habitat. As a graphical MUD it is considered a forerunner of modern MMORPGs unlike other online communities of the time (i.e. MUDs and massively multiplayer onlines with text-based interfaces). Habitat had a GUI and large user base of consumer-oriented users, and those elements in particular have made Habitat a much-cited project and acknowledged benchmark for the design of today's online communities that incorporate accelerated 3D computer graphics and immersive elements into their environments.

The Ulugh Beg Observatory is an observatory in Samarkand, Uzbekistan. Built in the 1420s by the Timurid astronomer Ulugh Beg. Islamic astronomers who worked at the observatory include Al-Kashi, Ali Qushji, and Ulugh Beg himself. The observatory was destroyed in 1449 and rediscovered in 1908.
