🔗 Jove (Jonathan's Own Version of Emacs)
JOVE (Jonathan's Own Version of Emacs) is an open-source, Emacs-like text editor, primarily intended for Unix-like operating systems. It also supports MS-DOS and Microsoft Windows. JOVE was inspired by Gosling Emacs but is much smaller and simpler, lacking Mocklisp. It was originally created in 1983 by Jonathan Payne while at Lincoln-Sudbury Regional High School in Massachusetts, United States on a PDP-11 minicomputer. JOVE was distributed with several releases of BSD Unix, including 2.9BSD, 4.3BSD-Reno and 4.4BSD-Lite2.
As of 2022, the latest development release of JOVE is version 4.17.4.4; the stable version is 4.16. Unlike GNU Emacs, JOVE does not support UTF-8.

🔗 Thank God for Mississippi
"Thank God for Mississippi" is an adage used in the United States, particularly in the South, that is generally used when discussing rankings of U.S. states. Since the U.S. state of Mississippi commonly ranks at or near the bottom of such rankings, residents of other states also ranking near the bottom may say, "Thank God for Mississippi," since the presence of that state in 50th place spares them the shame of being ranked last.
Examples include rankings of educational achievement, business opportunities, political progressiveness, obesity rates, overall health, the poverty rate, life expectancy, or other objective criteria of the quality of life or government in the 50 states. The phrase is in use even among state government officials and journalists, though occasionally with a slight twist.
Mississippi's poor reputation is such a common trope in American culture that when Mississippi does indeed rank well in something, the phrase "Thank God for Mississippi" may get brought up just to discuss how it does not apply in the given circumstance. The saying comes from Mississippi's poor ranking as compared to the other 49 states, not from a global perspective.

🔗 Weber–Fechner law
The Weber–Fechner law refers to two related hypotheses in the field of psychophysics, known as Weber's law and Fechner's law. Both laws relate to human perception, more specifically the relation between the actual change in a physical stimulus and the perceived change. This includes stimuli to all senses: vision, hearing, taste, touch, and smell.

🔗 Alternate Instruction Set
The Alternate Instruction Set (AIS) is a second 32-bit instruction set architecture found in some x86 CPUs made by VIA Technologies. On these VIA C3 processors, the second hidden processor mode is accessed by executing the x86 instruction ALTINST (0F 3F). If AIS mode has been enabled, the processor will perform a JMP EAX and begin executing AIS instructions at the address of the EAX register. Using AIS allows native access to the Centaur Technology-designed RISC core inside the processor.

🔗 Digital Mobile Radio
Digital mobile radio (DMR) is a limited open digital mobile radio standard defined in the European Telecommunications Standards Institute (ETSI) Standard TS 102 361 parts 1–4 and used in commercial products around the world. DMR, along with P25 phase II and NXDN are the main competitor technologies in achieving 6.25 kHz equivalent bandwidth using the proprietary AMBE+2 vocoder. DMR and P25 II both use two-slot TDMA in a 12.5 kHz channel, while NXDN uses discrete 6.25 kHz channels using frequency division and TETRA uses a four-slot TDMA in a 25 kHz channel.
DMR was designed with three tiers. DMR tiers I and II (conventional) were first published in 2005, and DMR III (Trunked version) was published in 2012, with manufacturers producing products within a few years of each publication.
The primary goal of the standard is to specify a digital system with low complexity, low cost and interoperability across brands, so radio communications purchasers are not locked into a proprietary solution. In practice, given the current limited scope of the DMR standard, many vendors have introduced proprietary features that make their product offerings non-interoperable with other brands.

🔗 Normally distributed and uncorrelated does not imply independent
In probability theory, although simple examples illustrate that linear uncorrelatedness of two random variables does not in general imply their independence, it is sometimes mistakenly thought that it does imply that when the two random variables are normally distributed. This article demonstrates that assumption of normal distributions does not have that consequence, although the multivariate normal distribution, including the bivariate normal distribution, does.
To say that the pair of random variables has a bivariate normal distribution means that every linear combination of and for constant (i.e. not random) coefficients and has a univariate normal distribution. In that case, if and are uncorrelated then they are independent. However, it is possible for two random variables and to be so distributed jointly that each one alone is marginally normally distributed, and they are uncorrelated, but they are not independent; examples are given below.

🔗 IBM and the Holocaust
IBM and the Holocaust: The Strategic Alliance between Nazi Germany and America's Most Powerful Corporation is a book by investigative journalist Edwin Black which details the business dealings of the American-based multinational corporation International Business Machines (IBM) and its German and other European subsidiaries with the government of Adolf Hitler during the 1930s and the years of World War II. In the book, published in 2001, Black outlined the way in which IBM's technology helped facilitate Nazi genocide through generation and tabulation of punch cards based upon national census data.

🔗 Cagot: a persecuted and despised minority found in the west of France
The Cagots (pronounced [ka.ɡo]) were a persecuted minority found in the west of France and northern Spain: the Navarrese Pyrenees, Basque provinces, Béarn, Aragón, Gascony and Brittany. Their name differed by province and the local language: Cagots, Gézitains, Gahets, and Gafets in Gascony; Agotes, Agotak, and Gafos in Basque country; Capots in Anjou and Languedoc; and Cacons, Cahets, Caqueux, and Caquins in Brittany. Evidence of the group exists back as far as AD 1000.
Cagots were shunned and hated; while restrictions varied by time and place, they were typically required to live in separate quarters in towns, called cagoteries, which were often on the far outskirts of the villages. Cagots were excluded from all political and social rights. They were not allowed to marry non-Cagots, enter taverns, hold cabarets, use public fountains, sell food or wine, touch food in the market, work with livestock, or enter mills. They were allowed to enter a church only by a special door and, during the service, a rail separated them from the other worshippers. Either they were altogether forbidden to partake of the sacrament, or the Eucharist was given to them on the end of a wooden spoon, while a holy water stoup was reserved for their exclusive use. They were compelled to wear a distinctive dress to which, in some places, was attached the foot of a goose or duck (whence they were sometimes called "Canards"). So pestilential was their touch considered that it was a crime for them to walk the common road barefooted or to drink from the same cup as non-Cagots. The Cagots were often restricted to the trades of carpenter, butcher, and rope-maker.
The Cagots were not an ethnic nor a religious group. They spoke the same language as the people in an area and generally kept the same religion as well. Their only distinguishing feature was their descent from families long identified as Cagots. Few consistent reasons were given as to why they were hated; accusations varied from Cagots being cretins, lepers, heretics, cannibals, to simply being intrinsically evil. The Cagots did have a culture of their own, but very little of it was written down or preserved; as a result, almost everything that is known about them relates to their persecution. The repression lasted through the Middle Ages, Renaissance, and Industrial Revolution, with the prejudice fading only in the 19th and 20th centuries.

🔗 Cognitive Distortion
A cognitive distortion is an exaggerated or irrational thought pattern involved in the onset and perpetuation of psychopathological states, especially those more influenced by psychosocial factors, such as depression and anxiety. Psychiatrist Aaron T. Beck laid the groundwork for the study of these distortions, and his student David D. Burns continued research on the topic. Burns, in The Feeling Good Handbook (1989), described personal and professional anecdotes related to cognitive distortions and their elimination.
Cognitive distortions are thoughts that cause individuals to perceive reality inaccurately. According to the cognitive model of Beck, a negative outlook on reality, sometimes called negative schemas (or schemata), is a factor in symptoms of emotional dysfunction and poorer subjective well-being. Specifically, negative thinking patterns reinforce negative emotions and thoughts. During difficult circumstances, these distorted thoughts can contribute to an overall negative outlook on the world and a depressive or anxious mental state.
Challenging and changing cognitive distortions is a key element of cognitive behavioral therapy (CBT).
