🔗 Job guarantee
A job guarantee (JG) is an economic policy proposal aimed at providing a sustainable solution to the dual problems of inflation and unemployment. Its aim is to create full employment and price stability, by having the state promise to hire unemployed workers as an employer of last resort (ELR).
The economic policy stance currently dominant around the world uses unemployment as a policy tool to control inflation; when inflation rises, the government pursues contractionary fiscal or monetary policy, creating a buffer stock of unemployed people, reducing wage demands, and ultimately inflation. When inflationary expectations subside, expansionary policy aims to produce the opposite effect. In Marxian terms, the unemployed serve as a reserve army of labor. By contrast, in a job guarantee program, a buffer stock of employed people (employed in the job guarantee program) provides the same protection against inflation without the social costs of unemployment, hence potentially fulfilling the dual mandate of full employment and price stability.

🔗 X Window System: Principles
The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems.
X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard. X does not mandate the user interface – this is handled by individual programs. As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces.
X originated at the Project Athena at Massachusetts Institute of Technology (MIT) in 1984. The X protocol has been at version 11 (hence "X11") since September 1987. The X.Org Foundation leads the X project, with the current reference implementation, X.Org Server, available as free and open source software under the MIT License and similar permissive licenses.

🔗 Mojibake
Mojibake (Japanese: 文字化け; IPA: [mod͡ʑibake]) is the garbled text that is the result of text being decoded using an unintended character encoding. The result is a systematic replacement of symbols with completely unrelated ones, often from a different writing system.
This display may include the generic replacement character ("�") in places where the binary representation is considered invalid. A replacement can also involve multiple consecutive symbols, as viewed in one encoding, when the same binary code constitutes one symbol in the other encoding. This is either because of differing constant length encoding (as in Asian 16-bit encodings vs European 8-bit encodings), or the use of variable length encodings (notably UTF-8 and UTF-16).
Failed rendering of glyphs due to either missing fonts or missing glyphs in a font is a different issue that is not to be confused with mojibake. Symptoms of this failed rendering include blocks with the code point displayed in hexadecimal or using the generic replacement character. Importantly, these replacements are valid and are the result of correct error handling by the software.

🔗 Agbogbloshie, the world's largest e-waste dump
Agbogbloshie is a nickname of a commercial district on the Korle Lagoon of the Odaw River, near the center of Accra, Ghana's capital city. Near the slum called "Old Fadama", the Agbogbloshie site became known as a destination for externally generated automobile and electronic scrap collected from mostly the western world. It was alleged to be at the center of a legal and illegal exportation network for the environmental dumping of electronic waste (e-waste) from industrialized nations. The Basel Action Network, a small NGO based in Seattle, has referred to Agbogbloshie as a "digital dumping ground", where they allege millions of tons of e-waste are processed each year.
However, repeated international studies have failed to confirm the allegations, which have been labelled an "e-waste hoax" by international reuse advocate WR3A. The most exhaustive study of the trade in used electronics in Nigeria, funded by UNEP and Basel Convention, revealed that from 540 000 tonnes of informally processed waste electronics, 52% of the material was recovered.
According to statistics from the World Bank, in large cities like Accra and Lagos the majority of households have owned televisions and computers for decades. The UN Report "Where are WEEE in Africa" (2012) disclosed that the majority of used electronics found in African dumps had not in fact been recently imported as scrap, but originated from these African cities. Agbogbloshie is situated on the banks of the Korle Lagoon, northwest of Accra's Central Business District. Roughly 40,000 Ghanaians inhabit the area, most of whom are migrants from rural areas. Due to its harsh living conditions and rampant crime, the area is nicknamed "Sodom and Gomorrah".
The Basel Convention prevents the transfrontier shipment of hazardous waste from developed to less developed countries. However, the Convention specifically allows export for reuse and repair under Annex Ix, B1110. While numerous international press reports have made reference to allegations that the majority of exports to Ghana are dumped, research by the US International Trade Commission found little evidence of unprocessed e-waste being shipped to Africa from the United States, a finding corroborated by the United Nations Environment Programme, MIT, Memorial University, Arizona State University, and other research. In 2013, the original source of the allegation blaming foreign dumping for the material found in Agbogbloshie recanted, or rather stated it had never made the claim that 80% of US e-waste is exported.
Whether domestically generated by residents of Ghana or imported, concern remains over methods of waste processing - especially burning - which emit toxic chemicals into the air, land and water. Exposure is especially hazardous to children, as these toxins are known to inhibit the development of the reproductive system, the nervous system, and especially the brain. Concerns about human health and the environment of Agbogbloshie continue to be raised as the area remains heavily polluted. In the 2000s, the Ghanaian government, with new funding and loans, implemented the Korle Lagoon Ecological Restoration Project (KLERP), an environmental remediation and restoration project that will address the pollution problem by dredging the lagoon and Odaw canal to improve drainage and flooding into the ocean.

🔗 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.

🔗 Déformation professionnelle
Déformation professionnelle (French: [defɔʁmasjɔ̃ pʁɔfɛsjɔnɛl], professional deformation or job conditioning) is a tendency to look at things from the point of view of one's own profession or special expertise, rather than from a broader or humane perspective. It is often translated as "professional deformation", though French déformation can also be translated as "distortion". The implication is that professional training, and its related socialization, often result in a distortion of the way one views the world. Nobel laureate Alexis Carrel observed, "Every specialist, owing to a well-known professional bias, believes that he understands the entire human being, while in reality he only grasps a tiny part of him."
As a term in psychology, it was likely coined by the Belgian sociologist Daniel Warnotte or Russian-American sociologist Pitirim Sorokin.

🔗 Bulverism is to “assume that your opponent is wrong, and explain his error”
Bulverism is a term for a rhetorical fallacy that combines circular reasoning with presumption or condescenscion. The method of Bulverism is to "assume that your opponent is wrong, and explain his error." The Bulverist assumes a speaker's argument is invalid or false and then explains why the speaker came to make that mistake, even if the opponents's claim is actually right, attacking the speaker or the speaker's motive. The term Bulverism was coined by C. S. Lewis to poke fun at a very serious error in thinking that, he alleges, recurs often in a variety of religious, political, and philosophical debates.
Similar to Antony Flew's "subject/motive shift", Bulverism is a fallacy of irrelevance. One accuses an argument of being wrong on the basis of the arguer's identity or motive, but these are strictly speaking irrelevant to the argument's validity or truth.

🔗 Q-Learning
Q-learning is a model-free reinforcement learning algorithm to learn a policy telling an agent what action to take under what circumstances. It does not require a model (hence the connotation "model-free") of the environment, and it can handle problems with stochastic transitions and rewards, without requiring adaptations.
For any finite Markov decision process (FMDP), Q-learning finds an optimal policy in the sense maximizing the expected value of the total reward over any and all successive steps, starting from the current state. Q-learning can identify an optimal action-selection policy for any given FMDP, given infinite exploration time and a partly-random policy. "Q" names the function that returns the reward used to provide the reinforcement and can be said to stand for the "quality" of an action taken in a given state.

🔗 Nothing-up-my-sleeve number
In cryptography, nothing-up-my-sleeve numbers are any numbers which, by their construction, are above suspicion of hidden properties. They are used in creating cryptographic functions such as hashes and ciphers. These algorithms often need randomized constants for mixing or initialization purposes. The cryptographer may wish to pick these values in a way that demonstrates the constants were not selected for a nefarious purpose, for example, to create a backdoor to the algorithm. These fears can be allayed by using numbers created in a way that leaves little room for adjustment. An example would be the use of initial digits from the number π as the constants. Using digits of π millions of places after the decimal point would not be considered trustworthy because the algorithm designer might have selected that starting point because it created a secret weakness the designer could later exploit—though even with natural-seeming selections, enough entropy exists in the possible choices that the utility of these numbers has been questioned.
Digits in the positional representations of real numbers such as π, e, and irrational roots are believed to appear with equal frequency (see normal number). Such numbers can be viewed as the opposite extreme of Chaitin–Kolmogorov random numbers in that they appear random but have very low information entropy. Their use is motivated by early controversy over the U.S. Government's 1975 Data Encryption Standard, which came under criticism because no explanation was supplied for the constants used in its S-box (though they were later found to have been carefully selected to protect against the then-classified technique of differential cryptanalysis). Thus a need was felt for a more transparent way to generate constants used in cryptography.
"Nothing up my sleeve" is a phrase associated with magicians, who sometimes preface a magic trick by holding open their sleeves to show they have no objects hidden inside.
