Abnormal behavior of birds in captivity has been found to occur among both domesticated and wild birds. Abnormal behavior can be defined in several ways. Statistically, 'abnormal' is when the occurrence, frequency or intensity of a behaviour varies statistically significantly, either more or less, from the normal value. This means that theoretically, almost any behaviour could become 'abnormal' in an individual. Less formally, 'abnormal' includes any activity judged to be outside the normal behaviour pattern for captive birds of that particular class or age. For example, running rather than flying may be a normal behaviour and regularly observed in one species, however, in another species it might be normal but becomes 'abnormal' if it reaches a high frequency, or in another species it is rarely observed and any incidence is considered 'abnormal'. This article does not include 'one-off' behaviours performed by individual birds that might be considered abnormal for that individual, unless these are performed repeatedly by other individuals in the species and are recognised as part of the ethogram of that species.

Most abnormal behaviours can be categorised collectively (e.g., eliminative, ingestive, stereotypies), however, many abnormal behaviours fall debatably into several of these categories and categorisation is therefore not attempted in this article. Abnormal behaviours here are considered to be related to captive housing but may also be due to medical conditions. The article does not include behaviours in birds that are genetically modified to express abnormal behaviour.

In geometry, flexagons are flat models, usually constructed by folding strips of paper, that can be flexed or folded in certain ways to reveal faces besides the two that were originally on the back and front.

Flexagons are usually square or rectangular (tetraflexagons) or hexagonal (hexaflexagons). A prefix can be added to the name to indicate the number of faces that the model can display, including the two faces (back and front) that are visible before flexing. For example, a hexaflexagon with a total of six faces is called a hexahexaflexagon.

In hexaflexagon theory (that is, concerning flexagons with six sides), flexagons are usually defined in terms of pats.

Two flexagons are equivalent if one can be transformed to the other by a series of pinches and rotations. Flexagon equivalence is an equivalence relation.

A tech union is a trade union for tech workers typically employed in high tech or information and communications technology sectors. Due to the evolving nature of technology and work, different government agencies have conflicting definitions for who is a tech worker. Most definitions include computer scientists, people working in IT, telecommunications, media and video gaming. Broader definitions include all workers required for a tech company to operate, including on-site service staff, contractors, and platform economy workers.

Memetics is a theory of the evolution of culture based on Darwinian principles with the meme as the unit of culture. The term "meme" was coined by biologist Richard Dawkins in his 1976 book The Selfish Gene, to illustrate the principle that he later called "Universal Darwinism". All evolutionary processes depend on information being copied, varied, and selected, a process also known as variation with selective retention. The information that is copied is called the replicator, and genes are the replicator for biological evolution. Dawkins proposed that the same process drives cultural evolution, and he called this second replicator the "meme". He gave as examples, tunes, catchphrases, fashions, and technologies. Like genes, memes are selfish replicators and have causal efficacy; in other words, their properties influence their chances of being copied and passed on. Some succeed because they are valuable or useful to their human hosts while others are more like viruses.

Just as genes can work together to form co-adapted gene complexes, so groups of memes acting together form co-adapted meme complexes or memeplexes. Memeplexes include (among many other things) languages, traditions, scientific theories, financial institutions, and religions. Dawkins famously referred to religions as "viruses of the mind".

Among proponents of memetics are psychologist Susan Blackmore, author of The Meme Machine, who argues that when our ancestors began imitating behaviours, they let loose a second replicator and co-evolved to become the "meme machines" that copy, vary, and select memes in culture. Philosopher Daniel Dennett develops memetics extensively, notably in his books Darwin's Dangerous Idea, and From Bacteria to Bach and Back. He describes the units of memes as "the smallest elements that replicate themselves with reliability and fecundity." and claims that "Human consciousness is itself a huge complex of memes." In The Beginning of Infinity, physicist David Deutsch contrasts static societies that depend on anti-rational memes suppressing innovation and creativity, with dynamic societies based on rational memes that encourage enlightenment values, scientific curiosity, and progress.

Criticisms of memetics include claims that memes do not exist, that the analogy with genes is false, that the units cannot be specified, that culture does not evolve through imitation, and that the sources of variation are intelligently designed rather than random. Critics of memetics include biologist Stephen Jay Gould who calls memetics a "meaningless metaphor". Philosopher Dan Sperber argues against memetics as a viable approach to cultural evolution because cultural items are not directly copied or imitated but are reproduced. Anthropologist Robert Boyd and biologist Peter Richerson work within the alternative, and more mainstream, field of cultural evolution theory and gene-culture coevolution. Dual inheritance theory has much in common with memetics but rejects the idea that memes are replicators. From this perspective, memetics is seen as just one of several approaches to cultural evolution and one that is generally considered less useful than the alternatives of gene-culture coevolution or dual inheritance theory. The main difference is that dual inheritance theory ultimately depends on biological advantage to genes, whereas memetics treats memes as a second replicator in its own right. Memetics also extends to the analysis of Internet culture and Internet memes.

Project 2025 is a plan to reshape the executive branch of the U.S. federal government in the event of a Republican victory in the 2024 U.S. presidential election. Established in 2022, the project seeks to recruit tens of thousands of conservatives to Washington, D.C., to replace existing federal civil service workers it characterizes as the "deep state", to further the objectives of the next Republican president. Although participants in the project cannot promote a specific presidential candidate, many have close ties to Donald Trump and the Trump 2024 presidential campaign. The plan would perform a swift takeover of the entire executive branch under a maximalist version of the unitary executive theory — a theory proposing the president of the United States has absolute power over the executive branch — upon inauguration.

The development of the plan is led by the The Heritage Foundation, an American conservative think tank, in collaboration with over 100 partners including Turning Point USA led by Charlie Kirk; the Conservative Partnership Institute including former Trump Chief of Staff Mark Meadows as senior partner; the Center for Renewing America led by former Trump-appointee Office of Management and Budget Director Russell Vought; and America First Legal led by former Trump Senior Advisor Stephen Miller.

Project 2025 envisions widespread changes across the entire government, particularly with regard to economic and social policy and the role of the federal government and federal agencies. The plan proposes slashing U.S. Department of Justice (DOJ) funding, dismantling the FBI and the Department of Homeland Security, gutting environmental and climate change regulations to favor fossil fuel production, and eliminating the cabinet Departments of Education and Commerce. Citing an anonymous source, The Washington Post reported Project 2025 includes immediately invoking the Insurrection Act of 1807 to deploy the military for domestic law enforcement and directing the DOJ to pursue Trump adversaries. Project Director Paul Dans, a former Trump administration official, said in September 2023 that Project 2025 is "systematically preparing to march into office and bring a new army, aligned, trained, and essentially weaponized conservatives ready to do battle against the deep state."

Project 2025 consists largely of a book of policy recommendations titled Mandate for Leadership: The Conservative Promise and an accompanying personnel database open for submissions. There is also an online course called the Presidential Administration Academy, and a guide to developing transition plans. Reactions to the plan included variously describing it as authoritarian, an attempt by Trump to become a dictator, and a path leading the United States towards autocracy, with several experts in law criticizing it for violating current constitutional laws that would undermine the rule of law and the separation of powers. Additionally, some conservatives and Republicans also criticized the plan, for example in relation to climate change. The Mandate states that "freedom is defined by God, not man."

Willy's Chocolate Experience was an unlicensed event based on the Charlie and the Chocolate Factory franchise, held in Glasgow, Scotland, in February 2024. The event was promoted as an immersive and interactive family experience, illustrated on its website with "dreamlike" AI-generated images. When customers discovered that the event was held in a sparsely decorated warehouse, many complained and the police were called to the venue. The event went viral on the Internet, garnering international media attention.

The event drew comparisons to the Tumblr fan convention DashCon in 2014 and Billy McFarland's Fyre Festival in 2017.

cowsay is a program that generates ASCII art pictures of a cow with a message. It can also generate pictures using pre-made images of other animals, such as Tux the Penguin, the Linux mascot. It is written in Perl. There is also a related program called cowthink, with cows with thought bubbles rather than speech bubbles. .cow files for cowsay exist which are able to produce different variants of "cows", with different kinds of "eyes", and so forth. It is sometimes used on IRC, desktop screenshots, and in software documentation. It is more or less a joke within hacker culture, but has been around long enough that its use is rather widespread. In 2007, it was highlighted as a Debian package of the day.
