🔗 Law

In contract law, a non-compete clause (often NCC), or covenant not to compete (CNC), is a clause under which one party (usually an employee) agrees not to enter into or start a similar profession or trade in competition against another party (usually the employer). Some courts refer to these as "restrictive covenants". As a contract provision, a CNC is bound by traditional contract requirements including the consideration doctrine.

The use of such clauses is premised on the possibility that upon their termination or resignation, an employee might begin working for a competitor or start a business, and gain competitive advantage by exploiting confidential information about their former employer's operations or trade secrets, or sensitive information such as customer/client lists, business practices, upcoming products, and marketing plans.

However, an over-broad CNC may prevent an employee from working elsewhere at all. English common law originally held any such constraint to be unenforceable under the public policy doctrine. Contemporary case law permits exceptions, but generally will only enforce CNCs to the extent necessary to protect the employer. Most jurisdictions in which such contracts have been examined by the courts have deemed CNCs to be legally binding so long as the clause contains reasonable limitations as to the geographical area and time period in which an employee of a company may not compete.

The extent to which non-compete clauses are legally allowed varies per jurisdiction. For example, the state of California in the United States invalidates non-compete-clauses for all but equity stakeholders in the sale of business interests.

"Fruit machine" is a term for a device developed in Canada by Frank Robert Wake that was supposed to be able to identify gay men (derogatorily referred to as "fruits"). The subjects were made to view pornography; the device then measured the diameter of the pupils of the eyes (pupillary response test), perspiration, and pulse for a supposed erotic response.

The "fruit machine" was employed in Canada in the 1950s and 1960s during a campaign to eliminate all gay men from the civil service, the Royal Canadian Mounted Police (RCMP), and the military. A substantial number of workers did lose their jobs. Although funding for the "fruit machine" project was cut off in the late 1960s, the investigations continued, and the RCMP collected files on over 9,000 "suspected" gay people.

The chair employed resembled that used by dentists. It had a pulley with a camera going towards the pupils, with a black box located in front of it that displayed pictures. The pictures ranged from the mundane to sexually explicit photos of men and women. It had previously been determined that the pupils would dilate in relation to the amount of interest in the picture per the technique termed 'the pupillary response test'.

People were first led to believe that the machine's purpose was to rate stress. After knowledge of its real purpose became widespread, few people volunteered for it.

🔗 Food and drink 🔗 Plants

Ensete ventricosum, commonly known as enset or ensete, Ethiopian banana, Abyssinian banana, and false banana, is an herbaceous species of flowering plant in the banana family Musaceae. The domesticated form of the plant is only cultivated in Ethiopia, where it provides the staple food for approximately 20 million people. The name Ensete ventricosum was first published in 1948 in the Kew Bulletin, 1947, p. 101. Its synonyms include Musa arnoldiana De Wild., Musa ventricosa Welw. and Musa ensete J.F.Gmel. In its wild form, it is native to the eastern edge of the Great African Plateau, extending northwards from South Africa through Mozambique, Zimbabwe, Malawi, Kenya, Uganda and Tanzania to Ethiopia, and west to the Congo, being found in high rainfall forests on mountains, and along forested ravines and streams.

🔗 Urban studies and planning

The Lewis–Mogridge position, named after David Lewis and Martin J. H. Mogridge, was formulated in 1990 and observes that as more roads are built, more traffic consequently fills these roads. Speed gains from some new roads can disappear within months, if not weeks. Sometimes, new roads help to reduce traffic jams, but in most cases, the congestion is only shifted to another junction.

The position reads traffic expands to meet the available road space (Mogridge, 1990). It is generally referred to as induced demand in the transport literature, and was posited as the "Iron Law of Congestion" by Anthony Downs. It is a special case of Jevons paradox (where the resource in question is traffic capacity), and relates to the Marchetti's constant (average commute times are similar in widely varying conditions).

Following the position, it is not generally concluded that new roads are never justified but that their development needs to consider the whole traffic system, which means understanding the movement of goods and people in detail as well as the motivation behind the movement.

The position is often used to understand problems caused by private transport such as congested roads in cities and on motorways. It can also be used to explain the success of schemes such as the London congestion charge.

The position, however, is not confined to private transport. Mogridge, a British transport researcher, concluded also that all road investment in a congested urban area will have the effect of reducing the average speed of the transport system as a whole: road and public transport. The relationship and overall equilibria are also known as the "Downs–Thomson paradox". However, according to Downs, the link between average speeds on public transport and private transport applies only "to regions in which the vast majority of peak-hour commuting is done on rapid transit systems with separate rights of way. Central London is an example, since in 2001 around 85 percent of all morning peak-period commuters into that area used public transit (including 77 percent on separate rights of way) and only 11 percent used private cars. When peak-hour travel equilibrium has been reached between the subway system and the major commuting roads, then the travel time required for any given trip is roughly equal on both modes."

Let's trim our hair in accordance with the socialist lifestyle (alternatively translated as Let us trim our hair in accordance with Socialist lifestyle) is a television program that was part of a North Korean government propaganda campaign promulgating grooming and dress standards in 2004–2005.

It was broadcast on state-run Korean Central Television in the capital of Pyongyang and clips from the program were later rebroadcast on the British channel BBC One. The program claimed that hair length can affect human intelligence, in part because of the deprivation to the rest of the body of nutrients required for hair to grow. However, although some researchers have proposed that brain and hair are in competition from an evolutionary standpoint, cutting hair has no influence on its rate of growth. It was part of a longstanding North Korean government restriction campaign against haircuts and fashions deemed at odds with "Socialist values".

Seki Takakazu (関 孝和, 1642 – December 5, 1708), also known as Seki Kōwa (関 孝和), was a Japanese mathematician and author of the Edo period.

Seki laid foundations for the subsequent development of Japanese mathematics known as wasan; and he has been described as "Japan's Newton".

He created a new algebraic notation system and, motivated by astronomical computations, did work on infinitesimal calculus and Diophantine equations. A contemporary of German polymath mathematician and philosopher Gottfried Leibniz and British mathematician Isaac Newton, Seki's work was independent. His successors later developed a school dominant in Japanese mathematics until the end of the Edo period.

While it is not clear how much of the achievements of wasan are Seki's, since many of them appear only in writings of his pupils, some of the results parallel or anticipate those discovered in Europe. For example, he is credited with the discovery of Bernoulli numbers. The resultant and determinant (the first in 1683, the complete version no later than 1710) are attributed to him. These achievements are astonishing, considering that Japanese mathematics before his appearance was at such a primitive stage. For example, comprehensive introduction of 13th century Chinese algebra was made as late as 1671, by Kazuyuki Sawaguchi.

The hedonic treadmill, also known as hedonic adaptation, is the observed tendency of humans to quickly return to a relatively stable level of happiness despite major positive or negative events or life changes. According to this theory, as a person makes more money, expectations and desires rise in tandem, which results in no permanent gain in happiness. Brickman and Donald T. Campbell coined the term in their essay "Hedonic Relativism and Planning the Good Society" (1971). The concept dates back centuries, to such writers as St. Augustine, cited in Robert Burton's 1621 Anatomy of Melancholy: "A true saying it is, Desire hath no rest, is infinite in itself, endless, and as one calls it, a perpetual rack, or horse-mill."

The hedonic (or happiness) set point has gained interest throughout the field of positive psychology where it has been developed and revised further. Given that hedonic adaptation generally demonstrates that a person's long-term happiness is not significantly affected by otherwise impacting events, positive psychology has concerned itself with the discovery of things that can lead to lasting changes in happiness levels.

BonziBuddy, stylized as BonziBUDDY, (pronounced BON-zee-bud-ee) was a freeware desktop virtual assistant made by Joe and Jay Bonzi. Upon a user's choice, it would share jokes and facts, manage downloading using its download manager, sing songs, and talk, among other functions.

The software used Microsoft Agent technology similar to Office Assistant, and originally sported Peedy, a green parrot and one of the characters available with Microsoft Agent. Later versions of BonziBuddy in May 2000 featured its own character: Bonzi, the purple gorilla. The program also used a text to speech voice to interact with the user. The voice was called Sydney and taken from an old Lernout & Hauspie Microsoft Speech API 4.0 package. It is often referred to in some software as Adult Male #2.

Some versions of the software were described as spyware and adware. BonziBuddy was discontinued in 2004 after the company behind it faced lawsuits regarding the software and was ordered to pay fines. Bonzi's website remained open after the discontinuation of BonziBuddy and was said to be a virus, but was shut down at the end of 2008.

Abū al-ʿAlāʾ al-Maʿarrī (Arabic: أبو العلاء المعري‎‎, full name أبو العلاء أحمد بن عبد الله بن سليمان التنوخي المعري‎ Abū al-ʿAlāʾ Aḥmad ibn ʿAbd Allāh ibn Sulaymān al-Tanūkhī al-Maʿarrī; December 973 – May 1057) was a blind Arab philosopher, poet, and writer. Despite holding a controversially irreligious worldview, he is regarded as one of the greatest classical Arabic poets.

Born in the city of Ma'arra during the Abbasid era, he studied in nearby Aleppo, then in Tripoli and Antioch. Producing popular poems in Baghdad, he nevertheless refused to sell his texts. In 1010, he returned to Syria after his mother began declining in health, and continued writing which gained him local respect.

Described as a "pessimistic freethinker", al-Ma'arri was a controversial rationalist of his time, citing reason as the chief source of truth and divine revelation. He was pessimistic about life, describing himself as "a double prisoner" of blindness and isolation. He attacked religious dogmas and practices, was equally critical and sarcastic about Judaism, Christianity, Islam and Zoroastrianism, and became a Deist.

He advocated social justice and lived a secluded, ascetic lifestyle. He was a vegan, known in his time as moral vegetarianism, entreating: "do not desire as food the flesh of slaughtered animals / Or the white milk of mothers who intended its pure draught / for their young". Al-Ma'arri held an antinatalist outlook, in line with his general pessimism, suggesting that children should not be born to spare them of the pains and suffering of life.

Al-Ma'arri wrote three main works that were popular in his time. Among his works are The Tinder Spark, Unnecessary Necessity, and The Epistle of Forgiveness. Al-Ma'arri never married and died at the age of 83 in the city where he was born, Ma'arrat al-Nu'man. In 2013, a statue of al-Ma'arri located in his Syrian hometown was beheaded by jihadists from the al-Nusra Front.

🔗 Computing

The R3000 is a 32-bit RISC microprocessor chipset developed by MIPS Computer Systems that implemented the MIPS I instruction set architecture (ISA). Introduced in June 1988, it was the second MIPS implementation, succeeding the R2000 as the flagship MIPS microprocessor. It operated at 20, 25 and 33.33 MHz.

The MIPS 1 instruction set is small compared to those of the contemporary 80x86 and 680x0 architectures, encoding only more commonly used operations and supporting few addressing modes. Combined with its fixed instruction length and only three different types of instruction formats, this simplified instruction decoding and processing. It employed a 5-stage instruction pipeline, enabling execution at a rate approaching one instruction per cycle, unusual for its time.

This MIPS generation supports up to four co-processors. In addition to the CPU core, the R3000 microprocessor includes a Control Processor (CP), which contains a Translation Lookaside Buffer and a Memory Management Unit. The CP works as a coprocessor. Besides the CP, the R3000 can also support an external R3010 numeric coprocessor and two other external coprocessors.

The R3000 CPU does not include level 1 cache. Instead, its on-chip cache controller operates external data and instruction caches of up to 256 KB each. It can access both caches during the same clock cycle.

The R3000 found much success and was used by many companies in their workstations and servers. Users included:

• Ardent Computer
• Digital Equipment Corporation (DEC) for their DECstation workstations and multiprocessor DECsystem servers
• Evans & Sutherland for their Vision (ESV) series workstations
• MIPS Computer Systems for their MIPS RISC/os Unix workstations and servers.
• NEC for their RISC EWS4800 workstations and UP4800 servers.
• Prime Computer
• Pyramid Technology
• Seiko Epson
• Silicon Graphics for their Professional IRIS, Personal IRIS and Indigo workstations, and the multiprocessor Power Series visualization systems
• Sony for their PlayStation and PlayStation 2 (SCPH-10000 to SCPH-700XX - clocked at 37.5 MHz for use as an I/O CPU and at 33.8 MHz for compatibility with PlayStation games) video game consoles, and NEWS workstations, as well as the Bemani System 573 Analog arcade unit, which runs on the R3000A.
• Tandem Computers for their NonStop Cyclone/R and CLX/R fault-tolerant servers
• Whitechapel Workstations for their Hitech-20 workstation
• New Horizons Probe

The R3000 was also used as an embedded microprocessor. When advances in technology rendered it obsolete for high-performance systems, it found continued use in lower-cost designs. Companies such as LSI Logic developed derivatives of the R3000 specifically for embedded systems.

The R3000 was a further development of the R2000 with minor improvements including larger TLB and a faster bus to the external caches. The R3000 die contained 115,000 transistors and measured about 75,000 square mils (48 mm²). MIPS was a fabless semiconductor company, so the R3000 was fabricated by MIPS partners including Integrated Device Technology (IDT), LSI Logic, NEC Corporation, Performance Semiconductor, and others. It was fabricated in a 1.2 μm complementary metal–oxide–semiconductor (CMOS) process with two levels of aluminium interconnect.

Derivatives of the R3000 for non-embedded applications include:

• R3000A - A further development by MIPS introduced in 1989. It operated at clock frequencies up to 40 MHz.
• PR3400 - Developed by Performance Semiconductor, introduced in May 1991, also at up to 40 MHz. It integrated the Performance Semiconductor PR3000A and PR3010A onto a single die.

Derivatives of the R3000 for embedded applications include:

• PR31700 - A 75 MHz microcontroller from Philips Semiconductors. Fabricated in a 0.35 μm process, delivered in a 208-pin LQFP, it operated at 3.3 V and dissipated only 0.35 W.
• RISController - A family of low-end microcontrollers from IDT. Models include the R3041, R3051, R3052, and R3081.
• TX3900 - A microcontroller from Toshiba.
• Mongoose-V - A radiation-hardened and expanded 10–15 MHz CPU for use on spacecraft, it is still in use today in applications such as NASA's New Horizons space probe.
