πŸ”— Stratton Oakmont, Inc. vs. Prodigy before Section 230

πŸ”— Law

Stratton Oakmont, Inc. v. Prodigy Services Co., 23 Media L. Rep. 1794 (N.Y. Sup. Ct. 1995), is a 1995 U.S. New York Supreme Court decision holding that online service providers could be held liable for the speech of their users. The ruling caused controversy among early supporters of the Internet, including some lawmakers, leading to the passage of Section 230 of the Communications Decency Act in 1996.

πŸ”— Fourth, fifth, and sixth derivatives of position

πŸ”— Physics

In physics, the fourth, fifth and sixth derivatives of position are defined as derivatives of the position vector with respect to time – with the first, second, and third derivatives being velocity, acceleration, and jerk, respectively. Unlike the first three derivatives, the higher-order derivatives are less common, thus their names are not as standardized, though the concept of a minimum snap trajectory has been used in robotics and is implemented in MATLAB.

The fourth derivative is often referred to as snap or jounce. The name "snap" for the fourth derivative led to crackle and pop for the fifth and sixth derivatives respectively, inspired by the Rice Krispies mascots Snap, Crackle, and Pop. These terms are occasionally used, though "sometimes somewhat facetiously".

πŸ”— Ketchup as a Vegetable

πŸ”— United States πŸ”— Politics πŸ”— Food and drink πŸ”— Health and fitness

The ketchup as a vegetable controversy stemmed from proposed regulations of school lunches by the USDA's Food and Nutrition Service (FNS) in 1981, early in the presidency of Ronald Reagan. The regulations were intended to provide meal planning flexibility to local school lunch administrators coping with cuts to the National School Lunch Program enacted by the Omnibus Reconciliation Acts of 1980 and 1981. The proposed changes allowed administrators to meet nutritional requirements by crediting food items not explicitly listed. While ketchup was not mentioned in the original regulations, pickle relish was used as an example of an item that could count as a vegetable.

A similar controversy arose in 2011, when Congress passed a bill prohibiting the USDA from increasing the amount of tomato paste required to constitute a vegetable; the bill allowed pizza with two tablespoons (30 mL) of tomato paste to qualify as a vegetable.

πŸ”— Salmonella-in-Eggs Controversy

πŸ”— Agriculture πŸ”— Food and drink πŸ”— Politics of the United Kingdom πŸ”— Poultry

The salmonella-in-eggs controversy was a political controversy in the United Kingdom caused by the Parliamentary Under-Secretary of State for Health, Edwina Currie's claims that "most of the egg production in this country, sadly, is now affected with salmonella" in 1988. These claims led to a 60 percent decline in egg sales over the next few weeks, and angered both politicians and those in the egg production industry. Currie's statement also resulted in the destruction of around 400 million eggs and the slaughter of around 4 million hens. The controversy dominated Currie's tenure as Parliamentary Under-Secretary of State for Health and resulted in her resignation two weeks later.

πŸ”— The Cuckoo's Egg

πŸ”— Espionage πŸ”— Books πŸ”— Computer Security πŸ”— Computer Security/Computing

The Cuckoo's Egg: Tracking a Spy Through the Maze of Computer Espionage is a 1989 book written by Clifford Stoll. It is his first-person account of the hunt for a computer hacker who broke into a computer at the Lawrence Berkeley National Laboratory (LBNL).

Stoll's use of the term extended the metaphor Cuckoo's egg from brood parasitism in birds to malware.

Konstantin Eduardovich Tsiolkovsky (Russian: ΠšΠΎΠ½ΡΡ‚Π°Π½Ρ‚ΠΈΜΠ½ Эдуа́рдович Циолко́вский; 17 SeptemberΒ [O.S. 5 September]Β 1857 – 19 September 1935) was a Russian and Soviet rocket scientist who pioneered astronautics. Along with the Frenchman Robert Esnault-Pelterie, the Germans Hermann Oberth and Fritz von Opel, and the American Robert H. Goddard, he is one of the founding fathers of modern rocketry and astronautics. His works later inspired leading Soviet rocket-engineers Sergei Korolev and Valentin Glushko, who contributed to the success of the Soviet space program.

Tsiolkovsky spent most of his life in a log house on the outskirts of Kaluga, about 200Β km (120Β mi) southwest of Moscow. A recluse by nature, his unusual habits made him seem bizarre to his fellow townsfolk.

πŸ”— Thousandth of an Inch

πŸ”— Metalworking πŸ”— Measurement

A thousandth of an inch is a derived unit of length in a system of units using inches. Equal to 1⁄1000 of an inch, a thousandth is commonly called a thou (used for both singular and plural) or particularly in North America a mil (plural mils).

The words are shortened forms of the English and Latin words for "thousand" (mille in Latin). In international engineering contexts, confusion can arise because mil is a formal unit name in North America but mil or mill is also a common colloquial clipped form of millimetre. The units are considerably different: a millimetre is approximately 39 mils.

Sophia Magdalena Scholl (9 May 1921 – 22 February 1943) was a German student and anti-Nazi political activist, active within the White Rose non-violent resistance group in Nazi Germany.

She was convicted of high treason after having been found distributing anti-war leaflets at the University of Munich (LMU) with her brother, Hans. For her actions, she was executed by guillotine. Since the 1970s, Scholl has been extensively commemorated for her anti-Nazi resistance work.

πŸ”— Cummingtonite

Cummingtonite ( KUM-ing-tΙ™-nyte) is a metamorphic amphibole with the chemical composition (Mg,Fe2+

, magnesium iron silicate hydroxide.

Monoclinic cummingtonite is compositionally similar and polymorphic with orthorhombic anthophyllite, which is a much more common form of magnesium-rich amphibole, the latter being metastable.

Cummingtonite shares few compositional similarities with alkali amphiboles such as arfvedsonite, glaucophane-riebeckite. There is little solubility between these minerals due to different crystal habit and inability of substitution between alkali elements and ferro-magnesian elements within the amphibole structure.

πŸ”— OODA Loop

πŸ”— Military history πŸ”— Military history/Military science, technology, and theory πŸ”— Systems πŸ”— Systems/Systems engineering

The OODA loop is the cycle observe–orient–decide–act, developed by military strategist and United States Air Force Colonel John Boyd. Boyd applied the concept to the combat operations process, often at the operational level during military campaigns. It is now also often applied to understand commercial operations and learning processes. The approach explains how agility can overcome raw power in dealing with human opponents. It is especially applicable to cyber security and cyberwarfare.

The OODA loop has become an important concept in litigation, business, law enforcement, management education, and military strategy. According to Boyd, decision-making occurs in a recurring cycle of observe–orient–decide–act. An entity (whether an individual or an organization) that can process this cycle quickly, observing and reacting to unfolding events more rapidly than an opponent, can thereby "get inside" the opponent's decision cycle and gain the advantage.
