๐ Justice Delayed Is Justice Denied
"Justice delayed is justice denied" is a legal maxim. It means that if legal redress or equitable relief to an injured party is available, but is not forthcoming in a timely fashion, it is effectively the same as having no remedy at all.
This principle is the basis for the right to a speedy trial and similar rights which are meant to expedite the legal system, because of the unfairness for the injured party who sustained the injury having little hope for timely and effective remedy and resolution. The phrase has become a rallying cry for legal reformers who view courts, tribunals, judges, arbitrators, administrative law judges, commissions or governments as acting too slowly in resolving legal issues โ either because the case is too complex, the existing system is too complex or overburdened, or because the issue or party in question lacks political favour. Individual cases may be affected by judicial hesitancy to make a decision. Statutes and court rules have tried to control the tendency; and judges may be subject to oversight and even discipline for persistent failures to decide matters timely, or accurately report their backlog. When a court takes a matter "under advisement" โ awaiting the issue of a judicial opinion, order or judgement and forestalls final adjudication of a lawsuit or resolution of a motion โ the issue of timeliness of the decision(s) comes into play.

๐ Electromagnetically Induced Acoustic Noise
Electromagnetically induced acoustic noise (and vibration), electromagnetically excited acoustic noise, or more commonly known as coil whine, is audible sound directly produced by materials vibrating under the excitation of electromagnetic forces. Some examples of this noise include the mains hum, hum of transformers, the whine of some rotating electric machines, or the buzz of fluorescent lamps. The hissing of high voltage transmission lines is due to corona discharge, not magnetism.
The phenomenon is also called audible magnetic noise, electromagnetic acoustic noise, lamination vibration or electromagnetically induced acoustic noise, or more rarely, electrical noise, or "coil noise", depending on the application. The term electromagnetic noise is generally avoided as the term is used in the field of electromagnetic compatibility, dealing with radio frequencies. The term electrical noise describes electrical perturbations occurring in electronic circuits, not sound. For the latter use, the terms electromagnetic vibrations or magnetic vibrations, focusing on the structural phenomenon are less ambiguous.
Acoustic noise and vibrations due to electromagnetic forces can be seen as the reciprocal of microphonics, which describes how a mechanical vibration or acoustic noise can induce an undesired electrical perturbation.

๐ DempsterโShafer theory
The theory of belief functions, also referred to as evidence theory or DempsterโShafer theory (DST), is a general framework for reasoning with uncertainty, with understood connections to other frameworks such as probability, possibility and imprecise probability theories. First introduced by Arthur P. Dempster in the context of statistical inference, the theory was later developed by Glenn Shafer into a general framework for modeling epistemic uncertaintyโa mathematical theory of evidence. The theory allows one to combine evidence from different sources and arrive at a degree of belief (represented by a mathematical object called belief function) that takes into account all the available evidence.
In a narrow sense, the term DempsterโShafer theory refers to the original conception of the theory by Dempster and Shafer. However, it is more common to use the term in the wider sense of the same general approach, as adapted to specific kinds of situations. In particular, many authors have proposed different rules for combining evidence, often with a view to handling conflicts in evidence better. The early contributions have also been the starting points of many important developments, including the transferable belief model and the theory of hints.

๐ Chinese room argument
The Chinese room argument holds that a digital computer executing a program cannot be shown to have a "mind", "understanding" or "consciousness", regardless of how intelligently or human-like the program may make the computer behave. The argument was first presented by philosopher John Searle in his paper, "Minds, Brains, and Programs", published in Behavioral and Brain Sciences in 1980. It has been widely discussed in the years since. The centerpiece of the argument is a thought experiment known as the Chinese room.
The argument is directed against the philosophical positions of functionalism and computationalism, which hold that the mind may be viewed as an information-processing system operating on formal symbols. Specifically, the argument is intended to refute a position Searle calls strong AI: "The appropriately programmed computer with the right inputs and outputs would thereby have a mind in exactly the same sense human beings have minds."
Although it was originally presented in reaction to the statements of artificial intelligence (AI) researchers, it is not an argument against the behavioural goals of AI research, because it does not limit the amount of intelligence a machine can display. The argument applies only to digital computers running programs and does not apply to machines in general.

๐ Hofstede's Cultural Dimensions Theory
Hofstede's cultural dimensions theory is a framework for cross-cultural psychology, developed by Geert Hofstede. It shows the effects of a society's culture on the values of its members, and how these values relate to behavior, using a structure derived from factor analysis.
Hofstede developed his original model as a result of using factor analysis to examine the results of a worldwide survey of employee values by IBM between 1967 and 1973. It has been refined since. The original theory proposed four dimensions along which cultural values could be analyzed: individualism-collectivism; uncertainty avoidance; power distance (strength of social hierarchy) and masculinity-femininity (task-orientation versus person-orientation). The Hofstede Cultural Dimensions factor analysis is based on extensive cultural preferences research conducted by Gert Jan Hofstede and his research teams. Hofstede based his research on national cultural preferences rather than individual cultural preferences. Hofstede included six key aspects of national culture country comparison scales, including: the power distance index (PDI), individualism vs. collectivism (IDV), motivation towards achievement and success (MAS, formerly masculinity versus femininity), uncertainty avoidance index (UAI), long term orientation versus short term normative orientation (LTO), and indulgence versus restraint (IVR). The PDI describes the degree to which authority is accepted and followed. The IDV measures the extent to which people look out for each other as a team or look out for themselves as an individual. MAS represents specific values that a society values. The UAI describes to what extent nations avoid the unknown. LTO expresses how societies either prioritize traditions or seek for the modern in their dealings with the present and the future. The IVR index is a comparison between a country's willingness to wait for long-term benefits by holding off on instant gratification, or preferences to no restraints on enjoying life at the present.
Independent research in Hong Kong led Hofstede to add a fifth dimension, long-term orientation, to cover aspects of values not discussed in the original paradigm. In 2010, Hofstede added a sixth dimension, indulgence versus self-restraint. Hofstede's work established a major research tradition in cross-cultural psychology and has also been drawn upon by researchers and consultants in many fields relating to international business and communication. The theory has been widely used in several fields as a paradigm for research, particularly in cross-cultural psychology, international management, and cross-cultural communication. It continues to be a major resource in cross-cultural fields.
๐ C++0x (upcoming C++ standard, includes lambda functions)
C++11 is a version of the standard for the programming language C++. It was approved by International Organization for Standardization (ISO) on 12 August 2011, replacing C++03, superseded by C++14 on 18 August 2014 and later, by C++17. The name follows the tradition of naming language versions by the publication year of the specification, though it was formerly named C++0x because it was expected to be published before 2010.
Although one of the design goals was to prefer changes to the libraries over changes to the core language, C++11 does make several additions to the core language. Areas of the core language that were significantly improved include multithreading support, generic programming support, uniform initialization, and performance. Significant changes were also made to the C++ Standard Library, incorporating most of the C++ Technical Report 1 (TR1) libraries, except the library of mathematical special functions.
C++11 was published as ISO/IEC 14882:2011 in September 2011 and is available for a fee. The working draft most similar to the published C++11 standard is N3337, dated 16 January 2012; it has only editorial corrections from the C++11 standard.

๐ Base58
Base58 is a group of binary-to-text encoding schemes used to represent large integers as alphanumeric text, introduced by Satoshi Nakamoto for use with Bitcoin. It has since been applied to other cryptocurrencies and applications. It is similar to Base64 but has been modified to avoid both non-alphanumeric characters and letters which might look ambiguous when printed. It is therefore designed for human users who manually enter the data, copying from some visual source, but also allows easy copy and paste because a double-click will usually select the whole string.
Compared with Base64, the following similar-looking letters are omitted: 0 (zero), O (capital o), I (capital i) and l (lower case L) as well as the non-alphanumeric characters + (plus) and / (slash). In contrast with Base64, the digits of the encoding do not line up well with byte boundaries of the original data. For this reason, the method is well-suited to encode large integers, but not designed to encode longer portions of binary data. The actual order of letters in the alphabet depends on the application, which is the reason why the term โBase58โ alone is not enough to fully describe the format. A variant, Base56, excludes 1 (one) and o (lowercase o) compared with Base 58.
Base58Check is a Base58 encoding format that unambiguously encodes the type of data in the first few characters and includes an error detection code in the last few characters.

๐ FacebookโCambridge Analytica data scandal
In the 2010s, personal data belonging to millions of Facebook users was collected by British consulting firm Cambridge Analytica for political advertising without informed consent.
The data was collected through an app called "This Is Your Digital Life", developed by data scientist Aleksandr Kogan and his company Global Science Research in 2013. The app consisted of a series of questions to build psychological profiles on users, and collected the personal data of the users' Facebook friends via Facebook's Open Graph platform. The app harvested the data of up to 87 million Facebook profiles. Cambridge Analytica used the data to analytically assist the 2016 presidential campaigns of Ted Cruz and Donald Trump. Cambridge Analytica was also widely accused of interfering with the Brexit referendum, although the official investigation recognised that the company was not involved "beyond some initial enquiries" and that "no significant breaches" took place.
In interviews with The Guardian and The New York Times, information about the data misuse was disclosed in March 2018 by Christopher Wylie, a former Cambridge Analytica employee. In response, Facebook apologized for their role in the data harvesting and their CEO Mark Zuckerberg testified in April 2018 in front of Congress. In July 2019, it was announced that Facebook was to be fined $5 billion by the Federal Trade Commission due to its privacy violations. In October 2019, Facebook agreed to pay a ยฃ500,000 fine to the UK Information Commissioner's Office for exposing the data of its users to a "serious risk of harm". In May 2018, Cambridge Analytica filed for Chapter 7 bankruptcy.
Other advertising agencies have been implementing various forms of psychological targeting for years and Facebook had patented a similar technology in 2012. Nevertheless, Cambridge Analytica's methods and their high-profile clientsโincluding the Trump presidential campaign and the UK's Leave.EU campaignโbrought the problems of psychological targeting that scholars have been warning against to public awareness. The scandal sparked an increased public interest in privacy and social media's influence on politics. The online movement #DeleteFacebook trended on Twitter.

๐ A Dog of Flanders
A Dog of Flanders is an 1872 novel by English author Marie Louise de la Ramรฉe published with her pseudonym "Ouida". It is about a Flemish boy named Nello and his dog, Patrasche and is set in Antwerp.
In Japan, Korea and the Philippines, the novel has been an extremely popular children's classic for decades and has been adapted into several Japanese films and anime. Since the 1980s, the Belgian board of tourism caught on to the phenomenon and built two monuments honoring the story to please East-Asian tourists. There is a small statue of Nello and Patrasche at the Kapelstraat in the Antwerp suburb of Hoboken, and a commemorative plaque in front of the Antwerp Cathedral donated by Toyota, that was later replaced by a marble statue of the two characters covered by a cobblestone blanket, created by the artist Batist Vermeulen.
