🔗 Stalin Note
The Stalin Note, also known as the March Note, was a document delivered to the representatives of the Western Allies (the United Kingdom, France, and the United States) from the Soviet Union in Germany on 10 March 1952. Soviet general secretary and premier Joseph Stalin put forth a proposal for a German reunification and neutralisation with no conditions on economic policies and with guarantees for "the rights of man and basic freedoms, including freedom of speech, press, religious persuasion, political conviction, and assembly" and free activity of democratic parties and organizations.
James Warburg, a member of the United States Senate Committee on Foreign Relations, testified before the committee on 28 March 1952 and observed that the Soviet proposal might be a bluff, but he thought that it seemed "that our government is afraid to call the bluff for the fear that it may not be a bluff at all" and might lead to "a free, neutral, and demilitarised Germany", which might be "subverted into Soviet orbit". That led to an exchange of notes between the West and the Soviet Union, which eventually ended after the West had insistence for a unified Germany to be free to join the European Defence Community and to be rearmed, demands that Stalin rejected.
West German Chancellor Konrad Adenauer and the Western Allies characterised Stalin's move as an aggressive action that attempted to stall the reintegration of West Germany. However, there was later a debate on whether a chance for reunification had been missed. Six years after the exchange, two West German ministers, Thomas Dehler and Gustav Heinemann, blamed Adenauer for not having explored the chance of reunification.
🔗 The Great Stink
The Great Stink was an event in central London in July and August 1858 during which the hot weather exacerbated the smell of untreated human waste and industrial effluent that was present on the banks of the River Thames. The problem had been mounting for some years, with an ageing and inadequate sewer system that emptied directly into the Thames. The miasma from the effluent was thought to transmit contagious diseases, and three outbreaks of cholera before the Great Stink were blamed on the ongoing problems with the river.
The smell, and fears of its possible effects, prompted action from the local and national administrators who had been considering possible solutions for the problem. The authorities accepted a proposal from the civil engineer Joseph Bazalgette to move the effluent eastwards along a series of interconnecting sewers that sloped towards outfalls beyond the metropolitan area. Work on high-, mid- and low-level systems for the new Northern and Southern Outfall Sewers started at the beginning of 1859 and lasted until 1875. To aid the drainage, pumping stations were placed to lift the sewage from lower levels into higher pipes. Two of the more ornate stations, Abbey Mills in Stratford and Crossness on the Erith Marshes, are listed for protection by English Heritage. Bazalgette's plan introduced the three embankments to London in which the sewers ran—the Victoria, Chelsea and Albert Embankments.
Bazalgette's work ensured that sewage was no longer dumped onto the shores of the Thames and brought an end to the cholera outbreaks; his actions are thought to have saved more lives than the efforts of any other Victorian official. His sewer system operates into the 21st century, servicing a city that has grown to a population of over eight million. The historian Peter Ackroyd argues that Bazalgette should be considered a hero of London.

🔗 "Where do you want to go today?"
“Where do you want to go today?” was the title of Microsoft’s second global image advertising campaign. The broadcast, print and outdoor advertising campaign was launched in November 1994 through the advertising agency Wieden+Kennedy. The campaign had Microsoft spending $100 million through July 1995, of which $25 million would be spent during the holiday shopping season ending in December 1994.
Tony Kaye directed a series of television ads filmed in Hong Kong, Prague and New York City that showed a broad range of people using their PCs. The television ads were first broadcast in Australia on November 13, the following day in both the United States and Canada, with Britain, France and Germany seeing the spots in subsequent days. An eight-page print ad described the personal computer as “an open opportunity for everybody” that “[facilitates] the flow of information so that good ideas—wherever they come from—can be shared”, and was placed in mass-market magazines including National Geographic, Newsweek, People, Rolling Stone and Sports Illustrated.
The New York Times described the campaign as taking “a winsome, humanistic approach to demystifying technology”. However, the Times reported in August 1995 that the response to Microsoft’s campaign in the advertising trade press had been “lukewarm” and quoted Brad Johnson of Advertising Age as stating that “Microsoft is on version 1.0 in advertising. Microsoft is not standing still. It will improve its advertising.” Microsoft’s Steve Ballmer, then the firm’s executive vice president, acknowledged that the response to the campaign had been “chilly”.
In June 1999, Microsoft announced that it would be ending its nearly five-year-long relationship with Wieden+Kennedy, shifting $100 million (~$166 million in 2022) in billings to McCann Erickson Worldwide Advertising in a split that was described by The New York Times as mutual. Dan Wieden, president and chief creative officer of the advertising agency, characterized the relationship with Microsoft as “intense” and said that it had “run its course”.

🔗 Continuation-Passing Style
In functional programming, continuation-passing style (CPS) is a style of programming in which control is passed explicitly in the form of a continuation. This is contrasted with direct style, which is the usual style of programming. Gerald Jay Sussman and Guy L. Steele, Jr. coined the phrase in AI Memo 349 (1975), which sets out the first version of the Scheme programming language.John C. Reynolds gives a detailed account of the numerous discoveries of continuations.
A function written in continuation-passing style takes an extra argument: an explicit "continuation"; i.e., a function of one argument. When the CPS function has computed its result value, it "returns" it by calling the continuation function with this value as the argument. That means that when invoking a CPS function, the calling function is required to supply a procedure to be invoked with the subroutine's "return" value. Expressing code in this form makes a number of things explicit which are implicit in direct style. These include: procedure returns, which become apparent as calls to a continuation; intermediate values, which are all given names; order of argument evaluation, which is made explicit; and tail calls, which simply call a procedure with the same continuation, unmodified, that was passed to the caller.
Programs can be automatically transformed from direct style to CPS. Functional and logic compilers often use CPS as an intermediate representation where a compiler for an imperative or procedural programming language would use static single assignment form (SSA). SSA is formally equivalent to a subset of CPS (excluding non-local control flow, which does not occur when CPS is used as intermediate representation). Functional compilers can also use A-normal form (ANF) (but only for languages requiring eager evaluation), rather than with 'thunks' (described in the examples below) in CPS. CPS is used more frequently by compilers than by programmers as a local or global style.

🔗 The Magic SysRq key
The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low-level commands regardless of the system's state. It is often used to recover from freezes, or to reboot a computer without corrupting the filesystem. Its effect is similar to the computer's hardware reset button (or power switch) but with many more options and much more control.
This key combination provides access to powerful features for software development and disaster recovery. In this sense, it can be considered a form of escape sequence. Principal among the offered commands are means to forcibly unmount file systems, kill processes, recover keyboard state, and write unwritten data to disk. With respect to these tasks, this feature serves as a tool of last resort.
The magic SysRq key cannot work under certain conditions, such as a kernel panic or a hardware failure preventing the kernel from running properly.

🔗 Child Labour in Cocoa Production
Child labour is a recurring issue in cocoa production. Cote d’Ivoire (also known in English as Ivory Coast) and Ghana, together produce nearly 60% of the world's cocoa each year. During the 2018/19 cocoa-growing season, research commissioned by the U.S. Department of Labor was conducted by NORC at the University of Chicago in these two countries and found that 1.48 million children are engaged in hazardous work on cocoa farms including working with sharp tools and agricultural chemicals and carrying heavy loads. That number of children is significant, representing 43 percent of all children living in agricultural households in cocoa growing areas. During the same period cocoa production in Cote d’Ivoire and Ghana increased 62 percent while the prevalence of child labour in cocoa production among all agricultural households increased 14 percentage points. Attention on this subject has focused on West Africa, which collectively supplies 69% of the world's cocoa, and Côte d'Ivoire, supplying 35%, in particular. The 2016 Global Estimates of Child Labour indicate that one-fifth of all African children are involved in child labour. Nine percent of African children are in hazardous work. It is estimated that more than 1.8 million children in West Africa are involved in growing cocoa. A 2013–14 survey commissioned by the Department of Labor and conducted by Tulane University found that an estimated 1.4 million children aged 5 years old to 11 years old worked in agriculture in cocoa-growing areas, while approximately 800,000 of them were engaged in hazardous work, including working with sharp tools and agricultural chemicals and carrying heavy loads. According to the NORC study, methodological differences between the 2018/9 survey and earlier ones, together with errors in the administration of the 2013/4 survey have made it challenging to document changes in the number of children engaged in child labour over the past five years.
A major study of the issue, published in Fortune magazine in the U.S. in March 2016, concluded that approximately 2.1 million children in West Africa "still do the dangerous and physically taxing work of harvesting cocoa". The report was doubtful as to whether the situation can be improved significantly.

🔗 Flow Chemistry
In flow chemistry, a chemical reaction is run in a continuously flowing stream rather than in batch production. In other words, pumps move fluid into a tube, and where tubes join one another, the fluids contact one another. If these fluids are reactive, a reaction takes place. Flow chemistry is a well-established technique for use at a large scale when manufacturing large quantities of a given material. However, the term has only been coined recently for its application on a laboratory scale. Often, microreactors are used.

🔗 Poincaré Recurrence Theorem
In mathematics and physics, the Poincaré recurrence theorem states that certain dynamical systems will, after a sufficiently long but finite time, return to a state arbitrarily close to (for continuous state systems), or exactly the same as (for discrete state systems), their initial state.
The Poincaré recurrence time is the length of time elapsed until the recurrence. This time may vary greatly depending on the exact initial state and required degree of closeness. The result applies to isolated mechanical systems subject to some constraints, e.g., all particles must be bound to a finite volume. The theorem is commonly discussed in the context of ergodic theory, dynamical systems and statistical mechanics. Systems to which the Poincaré recurrence theorem applies are called conservative systems.
The theorem is named after Henri Poincaré, who discussed it in 1890 and proved by Constantin Carathéodory using measure theory in 1919.

🔗 Ruin Value
Ruin value (German: Ruinenwert) is the concept that a building be designed such that if it eventually collapsed, it would leave behind aesthetically pleasing ruins that would last far longer without any maintenance at all. The idea was pioneered by German architect Albert Speer while planning for the 1936 Summer Olympics and published as "The Theory of Ruin Value" (Die Ruinenwerttheorie), although he was not its original inventor. The intention did not stretch only to the eventual collapse of the buildings, but rather assumed such buildings were inherently better designed and more imposing during their period of use.
The idea was supported by Adolf Hitler, who planned for such ruins to be a symbol of the greatness of the Third Reich, just as Ancient Greek and Roman ruins were symbolic of those civilisations.
