On 19 July 2024, a faulty update to security software produced by CrowdStrike, an American cybersecurity company, caused innumerable computers and virtual machines running Microsoft Windows to crash. Businesses and governments around the globe were affected by what one expert called the "largest IT outage in history".

Among the industries that were disrupted were airlines, airports, banks, hotels, hospitals, stock markets, and broadcasting; governmental services such as emergency numbers and websites were also affected. The error was discovered and a fix was made on the same day, but the outage continued to delay airline flights, cause problems in processing electronic payments, and disrupt emergency services.

๐Ÿ”— SKI Combinator Calculus

๐Ÿ”— Mathematics

The SKI combinator calculus is a combinatory logic system and a computational system. It can be thought of as a computer programming language, though it is not convenient for writing software. Instead, it is important in the mathematical theory of algorithms because it is an extremely simple Turing complete language. It can be likened to a reduced version of the untyped lambda calculus. It was introduced by Moses Schรถnfinkel and Haskell Curry.

All operations in lambda calculus can be encoded via abstraction elimination into the SKI calculus as binary trees whose leaves are one of the three symbols S, K, and I (called combinators).

๐Ÿ”— Museum Fatigue

๐Ÿ”— Psychology ๐Ÿ”— Museums

Museum fatigue is a state of physical or mental fatigue caused by the experience of exhibits in museums and similar cultural institutions. The collection of phenomena that characterize museum fatigue was first described in 1916, and has since received widespread attention in popular and scientific contexts.

The first known description of museum fatigue was made by Benjamin Ives Gilman in the January 1916 edition of The Scientific Monthly. Gilman mainly focused on the efforts of museum fatigue on how the viewing displays are placed. Gilman went on to say that the way the displays were presented caused museum fatigue. In other later studies, Edward Robinson in 1928 spoke more about museum fatigue, specifically of four museums that showed a lot of characteristics of museum fatigue because of how the displays were placed. Arthur Melton provided more proof for Robinson by observing visitors' interest in the displays decreased as the number of displays increased.

In a more recent study of the phenomenon, Falk, Koran, Direking, and Dreblow studied museum fatigue at the Florida Museum of Natural History in 1985. While observing visitors they noticed a pattern of high interest in anything in the museum for about 30 minutes and then a decrease in interest. In 1997โ€“1998, Beverly Serrell in her research determined that in less than 20 minutes people became apathetic towards the museum. Museum fatigue has also been applied in zoos to see if they had the same effect. In one study in 1986, Bitgood, Patterson, and Benefeld observed the reptile house of the Birmingham Zoo. While observing they noticed that the pattern was different from museum fatigue.

๐Ÿ”— Audio Induction Loop

๐Ÿ”— Disability

Audio induction loop systems, also called audio-frequency induction loops (AFILs) or hearing loops, are an assistive listening technology for individuals with reduced ranges of hearing.

A hearing loop consists of one or more physical loops of cable which are placed around a designated area, usually a room or a building. The cable generates an electromagnetic field throughout the looped space which can be picked up by a telecoil-equipped hearing aid, a cochlear implant (CI) processor, or a specialized hand-held hearing loop receiver for individuals without telecoil-compatible hearing aids.

The loops carry baseband audio-frequency currents; no carrier signal is used. The benefit is that it allows the sound source of interestย โ€“ whether a musical performance or a ticket taker's side of the conversationย โ€“ to be transmitted to the hearing-impaired listener clearly and free of other distracting noise in the environment. Typical installation sites include concert halls, ticket kiosks, high-traffic public buildings (for PA announcements), auditoriums, places of worship, courtrooms, meeting rooms, and homes.

In the United Kingdom, as an aid for disability, their provision, where reasonably possible, is required by the Equality Act 2010 and previously by the Disability Discrimination Act 1995, and they are available in "the back seats of all London taxis, which have a little microphone embedded in the dashboard in front of the driver; at 18,000 post offices in the U.K.; at most churches and cathedrals", according to Prof. David G. Myers.

In the United States, an alternative technology using FM transmission to "neck loop" receivers was more widely adopted due to economic advantages. In comparison, hearing loop systems require a greater initial investment by the facility operator, but offer greater convenience and avoid the social stigma and hygienic concerns entailed by the FM system's paraphernalia for those who have hearing aids.

Another alternative system, used primarily in theatres, uses invisible infrared radiation; compatible headsets can pick up the modulated infrared energy to reproduce sound.

๐Ÿ”— Schafferโ€“Vega Diversity System

๐Ÿ”— Professional sound production ๐Ÿ”— Stagecraft

The Schafferโ€“Vega diversity system (SVDS) was a wireless guitar system developed in 1975โ€“76, engineered and prototyped by Ken Schaffer in New York City, and manufactured by the Vega Corporation, El Monte, California. A handheld microphone version was introduced in 1977.

The system was the first cordless system to be adopted by major rock acts because it solved technical problems common to earlier wireless systems. The reliable sound and freedom of movement it provided paved the way for bands to tour with large multi-level stages in arenas. Schaffer-Vegas were used in the late 1970s and early 1980s by many rock bands such as Pink Floyd (namely guitarist David Gilmour), the Rolling Stones, AC/DC and Kiss.

๐Ÿ”— Wireless Application Protocol

๐Ÿ”— Computing ๐Ÿ”— Telecommunications ๐Ÿ”— Computing/Networking

Wireless Application Protocol (WAP) is a now obsolete technical standard for accessing information over a mobile wireless network. Introduced in 1999, WAP allowed at launch users with compatible mobile devices to browse content such as news, weather and sports scores provided by mobile network operators, specially designed for the limited capabilities of a mobile device. The Japanese i-mode system offered another major competing wireless data standard.

Before the introduction of WAP, mobile service providers had limited opportunities to offer interactive data services, but needed interactivity to support Internet and Web applications. Although hyped at launch, WAP suffered from much criticism. However the introduction of GPRS networks, offering a faster speed, led to an improvement in the WAP experience. WAP content was accessed using a WAP browser, which is like a standard web browser but designed for reading pages specific for WAP, instead of HTML. By the 2010s it had been largely superseded by more modern standards such as XHTML. Modern phones have proper Web browsers, so they do not need WAP markup for compatibility, and therefore, most are no longer able to render and display pages written in WML, WAP's markup language.

๐Ÿ”— Toxoplasma Gondii

๐Ÿ”— Medicine ๐Ÿ”— Cats ๐Ÿ”— Microbiology ๐Ÿ”— Veterinary medicine

Toxoplasma gondii () is a parasitic protozoan (specifically an apicomplexan) that causes toxoplasmosis. Found worldwide, T.ย gondii is capable of infecting virtually all warm-blooded animals,:โ€Š1โ€Š but felids are the only known definitive hosts in which the parasite may undergo sexual reproduction.

In rodents, T.ย gondii alters behavior in ways that increase the rodents' chances of being preyed upon by felids. Support for this "manipulation hypothesis" stems from studies showing that T.ย gondii-infected rats have a decreased aversion to cat urine while infection in mice lowers general anxiety, increases explorative behaviors and increases a loss of aversion to predators in general. Because cats are one of the only hosts within which T.ย gondii can sexually reproduce, such behavioral manipulations are thought to be evolutionary adaptations that increase the parasite's reproductive success since rodents that do not avoid cat habitations will more likely become cat prey. The primary mechanisms of T.ย gondiiโ€“induced behavioral changes in rodents occur through epigenetic remodeling in neurons that govern the relevant behaviors (e.g. hypomethylation of arginine vasopressin-related genes in the medial amygdala, which greatly decrease predator aversion).

In humans, particularly infants and those with weakened immunity, T.ย gondii infection is generally asymptomatic but may lead to a serious case of toxoplasmosis. T.ย gondii can initially cause mild, flu-like symptoms in the first few weeks following exposure, but otherwise, healthy human adults are asymptomatic. This asymptomatic state of infection is referred to as a latent infection, and it has been associated with numerous subtle behavioral, psychiatric, and personality alterations in humans. Behavioral changes observed between infected and non-infected humans include a decreased aversion to cat urine (but with divergent trajectories by gender) and an increased risk of schizophrenia. Preliminary evidence has suggested that T.ย gondii infection may induce some of the same alterations in the human brain as those observed in rodents. Many of these associations have been strongly debated and newer studies have found them to be weak, concluding:

On the whole, there was little evidence that T.ย gondii was related to increased risk of psychiatric disorder, poor impulse control, personality aberrations, or neurocognitive impairment.

T. gondii is one of the most common parasites in developed countries; serological studies estimate that up to 50% of the global population has been exposed to, and may be chronically infected with, T.ย gondii; although infection rates differ significantly from country to country. Estimates have shown the highest IgG seroprevalence to be in Ethiopia, at 64.2%, as of 2018.
