🔗 Medicine 🔗 Mexico

The cocoliztli epidemic or the great pestilence is a term given to millions of deaths in the territory of New Spain in present-day Mexico in the 16th century attributed to one or more illnesses collectively called cocoliztli, a mysterious illness characterized by high fevers and bleeding. It ravaged the Mexican highlands in epidemic proportions. The disease became known as Cocoliztli by the native Aztecs, and had devastating effects on the area’s demography, particularly for the indigenous people. Based on the death toll, this outbreak is often referred to as the worst disease epidemic in the history of Mexico. Subsequent outbreaks continued to baffle both Spanish and native doctors, with little consensus among modern researchers on the pathogenesis. However, recent bacterial genomic studies have suggested that Salmonella, specifically a serotype of Salmonella enterica known as Paratyphi C, was at least partially responsible for this initial outbreak. It might have also been an indigenous viral hemorrhagic fever, perhaps exacerbated by the worst droughts to affect that region in 500 years, as well as living conditions for indigenous peoples of Mexico in the wake of the Spanish conquest (c. 1519).

🔗 Physiology

Monocular rivalry is a phenomenon of human visual perception that occurs when two different images are optically superimposed. During prolonged viewing, one image becomes clearer than the other for a few moments, then the other image becomes clearer than the first for a few moments. These alternations in clarity continue at random for as long as one looks. Occasionally one image will become exclusively visible and the other image invisible.

In the demonstration, one image is a green grating and the other is a red grating. During prolonged inspection, the viewer can see the green grating as clearer than the red grating for a few moments, then the reverse. Occasionally the green grating will be all that is visible and occasionally the red grating will be all that is visible. Occasionally, at transitions, one will briefly see irregular composites of the two gratings (such as the red and green gratings superimposed but with one or two bars of the green grating invisible).

Monocular rivalry is easier to see when the component stimuli are of opposite colors, but it also occurs when the component stimuli have the same colors. As long as the two component stimuli differ spatiotemporally in some way, such as orientation (as shown), spatial frequency, or direction of movement, monocular rivalry can be seen.

🔗 Aviation 🔗 Organized Labour

The Professional Air Traffic Controllers Organization or PATCO was a United States trade union that operated from 1968 until its decertification in 1981 following an illegal strike that was broken by the Reagan Administration. According to labor historian Joseph A. McCartin, the 1981 strike and defeat of PATCO was "one of the most important events in late twentieth century U.S. labor history".

🔗 Comics

Potrzebie (; Polish pronunciation: [pɔtˈʂɛbʲe] dative/locative of potrzeba, "a need") is a Polish word popularized by its non sequitur use as a running gag in the early issues of Mad not long after the comic book began in 1952.

🔗 Mathematics

In mathematics, the Bernoulli numbers B_n are a sequence of rational numbers which occur frequently in number theory. The Bernoulli numbers appear in (and can be defined by) the Taylor series expansions of the tangent and hyperbolic tangent functions, in Faulhaber's formula for the sum of m-th powers of the first n positive integers, in the Euler–Maclaurin formula, and in expressions for certain values of the Riemann zeta function.

The values of the first 20 Bernoulli numbers are given in the adjacent table. Two conventions are used in the literature, denoted here by ${\displaystyle B_{n}^{-{}}}$ and ${\displaystyle B_{n}^{+{}}}$; they differ only for n = 1, where ${\displaystyle B_{1}^{-{}}=-1/2}$ and ${\displaystyle B_{1}^{+{}}=+1/2}$. For every odd n > 1, B_n = 0. For every even n > 0, B_n is negative if n is divisible by 4 and positive otherwise. The Bernoulli numbers are special values of the Bernoulli polynomials ${\displaystyle B_{n}(x)}$, with ${\displaystyle B_{n}^{-{}}=B_{n}(0)}$ and ${\displaystyle B_{n}^{+}=B_{n}(1)}$ (Weisstein 2016).

The Bernoulli numbers were discovered around the same time by the Swiss mathematician Jacob Bernoulli, after whom they are named, and independently by Japanese mathematician Seki Kōwa. Seki's discovery was posthumously published in 1712 (Selin 1997, p. 891; Smith & Mikami 1914, p. 108) in his work Katsuyo Sampo; Bernoulli's, also posthumously, in his Ars Conjectandi of 1713. Ada Lovelace's note G on the Analytical Engine from 1842 describes an algorithm for generating Bernoulli numbers with Babbage's machine (Menabrea 1842, Note G). As a result, the Bernoulli numbers have the distinction of being the subject of the first published complex computer program.

🔗 History 🔗 France 🔗 Medicine 🔗 Dance

The Dancing Plague of 1518, or Dance Epidemic of 1518, was a case of dancing mania that occurred in Strasbourg, Alsace (modern-day France), in the Holy Roman Empire from July 1518 to September 1518. Somewhere between 50 and 400 people took to dancing for weeks.

🔗 Computing 🔗 Computing/Computer hardware 🔗 Computing/Software

On the x86 computer architecture, a triple fault is a special kind of exception generated by the CPU when an exception occurs while the CPU is trying to invoke the double fault exception handler, which itself handles exceptions occurring while trying to invoke a regular exception handler.

x86 processors beginning with the 80286 will cause a shutdown cycle to occur when a triple fault is encountered. This typically causes the motherboard hardware to initiate a CPU reset, which, in turn, causes the whole computer to reboot.

🔗 United States 🔗 International relations 🔗 Business 🔗 Politics 🔗 Trade 🔗 Taxation 🔗 Presidents of the United States 🔗 Presidents of the United States/Donald Trump

"Trump Always Chickens Out" (TACO) is a pejorative description of the perceived tendency of US president Donald Trump to make threats, only to later delay or renege on them as a way to increase time for negotiations and for markets to rebound. The phrase was popularized in May 2025 after the many threats and reversals during the trade war he initiated with his "Liberation Day" tariffs. On Wall Street, a TACO trade is buying stocks cheaply after a tariff announcement pushes stocks lower, then selling them at a profit after the tariffs are delayed or reduced and the market rebounds.

By 2026, TACO was also used for Trump's decisions in the realm of foreign policy, specifically his reversal of threats to annex Greenland, his attempt to find an abrupt exit for the escalating 2026 Iran War as global securities began to fall due to the rise in oil prices, and his last-minute ceasefire deal for the Iran War itself before the deadline for the American bombing campaign.

🔗 Biography 🔗 Linux

Wim Odilia Georges Taymans is a Belgian software developer based in Malaga, Spain. He is the original developer behind GStreamer and Pipewire technologies, which provide core multimedia processing capabilities to many modern operating systems.

Taymans started his career in multimedia development on the Commodore 64 and the Amiga writing various games and demos. In 1994 he installed the Linux operating system on his Amiga and has since been involved with the development of various multimedia technologies for the Linux platform. His first efforts on Linux were some assembly optimizations for the rtjpeg library; later, he worked on the Trinity video editor before teaming up with Erik Walthinsen to create the GStreamer multimedia framework.

In 2004 he started working for Fluendo in Spain as employee number 3. While working for Fluendo he designed and wrote most of the 0.10 release series of GStreamer. In July 2007 he left Fluendo and joined with Collabora. As part of his job at Collabora he maintained and developed GStreamer further. In November 2013, Taymans started as a Principal Software Engineer at Red Hat spending most of his time working on upstream GStreamer.

Taymans was the main architect and developer behind the GStreamer 1.0 release which came out on September 24, 2012.

In July 2015, Taymans announced that he was designing Pinos, which became PipeWire, from his position as Principal Engineer at Red Hat. PipeWire is a server for handling audio and video streams on Linux.
