Garbage in, garbage out (GIGO) in the field of computer science or information and communications technology refers to the fact that computers, since they operate by logical processes, will unquestioningly process unintended, even nonsensical, input data (‘garbage in’) and produce undesired, often nonsensical, output (‘garbage out’). The principle applies to other fields as well.
The underlying principle was noted by the inventor of the first programmable computing device design: ‘On two occasions I have been asked, ‘Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?’ … I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.’

Mechanophilia [muh-kan-uh-fil-ee-uh] is a paraphilia (atypical sexuality) involving a sexual attraction to machines. It is a crime in some nations, such as the UK, with perpetrators placed on a sex-offender registry. Motorcycles in particular are often portrayed as sexualized fetish objects to those who desire them. Designers such as Francis Picabia and Filippo Tommaso Marinetti have been said to have exploited the sexual attraction of automobiles. In 2008, an American named Edward Smith admitted to ‘having sex’ with 1000 cars.
Biologist Edward O. Wilson is quoted describing mechanophilia, the love of machines, as ‘a special case of ‘biophilia,” the instinctive bond between human beings and other living (or lifelike) systems. Conversely, psychologists such as Erich Fromm would see it as a form of necrophilia.

Jugaad [joo-gard] is a colloquial Hindi and Punjabi word that can mean an innovative fix or a simple work-around, used for solutions that bend rules, or a resource that can be used as such, or a person who can solve a complicated issue. It is used as much to describe enterprising street mechanics as for political fixers. This meaning is often used to signify creativity to make existing things work or to create new things with meagre resources.
Jugaad is similar to the Western concepts of a ‘hack’ or ‘kludge,’ or to bodge or (‘British English’), but can be thought of more as a survival tactic than a mere workaround. But all such concepts express a need to do what needs to be done, without regard to what is conventionally supposed to be possible.

A whispering gallery is a circular room in which whispers can be heard clearly across great distances. The sound is carried by waves, known as ‘whispering-gallery waves,’ that travel around the circumference clinging to the walls, an effect that was discovered in the whispering gallery of St Paul’s Cathedral in London. Other historical examples are the Gol Gumbaz mausoleum in India and the Echo Wall of the Temple of Heaven in Beijing.
The gallery may also be in the form of an ellipse or ellipsoid, with an accessible point at each focus. In this case, when a visitor stands at one focus and whispers, the line of sound emanating from this focus reflects directly to the focus at the other end of the gallery, where the whispers may be heard. In a similar way, two large concave parabolic dishes, serving as acoustic mirrors, may be erected facing each other in a room or outdoors to serve as a whispering gallery, a common feature of science museums. Egg-shaped galleries, such as the Golghar Granary in India, and irregularly shaped smooth-walled galleries in the form of caves, such as the Ear of Dionysius in Syracuse, also exist.

Chromadepth is a patented system from the company Chromatek (a subsidiary of American Paper Optics since 2002) that produces a stereoscopic effect based upon differences in the diffraction of color through a special prism-like holographic film. Chromadepth glasses purposely exacerbate chromatic aberration (the failure of a lens to focus all colors to the same convergence point) and give the illusion of colors taking up different positions in space, with red being in front, and blue being in back.
The effect works particularly well with the sky, sea or grass as a background, and redder objects in the foreground. From front to back the scheme follows the visible light spectrum, from red to orange, yellow, green and blue. This means any color is associated in a fixed fashion with a certain depth when viewing. As a result, ChromaDepth works best with artificially produced or enhanced pictures, since the color indicates the depth.

You ain’t gonna need it (YAGNI) is a principle of extreme programming (XP) that states a programmer should not add functionality until deemed necessary. XP co-founder Ron Jeffries said: ‘Always implement things when you actually need them, never when you just foresee that you need them.’ Jeffries argues that prematurely adding features leads to software bloat, feature creep, and takes time away from core functionality improvement.
YAGNI is a principle behind the XP practice of ‘do the simplest thing that could possibly work’ (DTSTTCPW). It is meant to be used in combination with several other practices, such as continuous refactoring (code reorganization), continuous automated unit testing, and continuous integration (conforming code segments work within the larger codebase). However, the efficacy of YAGNI, even when considered in combination with safeguards, is controversial.

A stampede is uncontrolled concerted running as an act of mass impulse among herd animals or a crowd of people. Cattle are particularly prone to stampedes. Any sudden, unusual event can set one off, such as a horse shaking itself, a lightning strike, or even just a tumbleweed. Other species that stampede include elephants, walruses, wild horses, rhinoceros, and humans. Human crushes often occur during religious pilgrimages and professional sporting and music events. They also occur in times of panic (e.g. as a result of a fire or explosion) as people try to get away.
Crushes are very often referred to as stampedes but, unlike true stampedes, they can cause many deaths. They typically occur when members at the back of a large crowd continue pushing forward not knowing that those at the front are being crushed, or because of something that forces them to move. It has been suggested that crowd density rather than size is important, with a density of about four people per square meter beginning to be dangerous, even if the crowd is not very large.

Unstructured Data refers to information that is not organized in a predefined manner. Properly formated computerized data is stored in a database (making it easily retrievable) and labeled with metadata (‘data about data,’ e.g., author, subject, size). Unstructured information has missing or conflicting metadata and may lack contextual clues that make it difficult to understand using traditional programs.
Techniques such as data mining, Natural Language Processing (NLP), and ‘noisy-text’ analytics provide different methods to find patterns in, or otherwise interpret, this information. NLP is a field in Artificial Intelligence, related to linguistics that attempts to program computers to understand human languages. There is considerable commercial interest in the field because of its application to news-gathering, text categorization, voice-activation, archiving, and large-scale content-analysis.

Scam baiting is a form of Internet vigilantism, where the vigilante poses as a potential victim to the scammer in order to waste their time and resources, gather information that will be of use to authorities, and publicly expose the scammer. It is primarily used to thwart advance-fee fraud scams (e.g. ‘Nigerian Prince’ scams) and can be done out of a sense of civic duty (activism) by documenting scammers tools and methods, warning potential victims, or taking down fake websites.
A bait is very simply initiated, by answering a scam email, from a throwaway email account, i.e. one that is only used for baiting and untraceable back to the actual owner. The baiter then pretends to be receptive to the financial hook that the scammer is using, but requires increasingly ridiculous forms of security from the scammer before turning over funds. Scam baiters typically use jest in their attacks. However, some scam baiters have been accused of abject mockery, racism, and homophobia, and even scamming themselves.

Sukkah [sook-uh] City was a 2010 architectural design competition and work of installation art planned in New York City’s Union Square Park. A sukkah is the name given to a structure described in Torah (Jewish Bible). The Children of Israel were instructed to annually commemorate their Exodus from Egypt by dwelling for seven days every autumn in temporary structures reminiscent of those in which they lived during their 40 years of wandering in the desert before settling in the Land of Israel. Many Jews continue this practice to this day, and Sukkah City aims to re-imagine the sukkah in contemporary design.
A committee of art critics and architects selected 12 winners from a field of over 600 entries. The twelve winning sukkot were constructed at Brooklyn’s Gowanus Studio Space, and driven by truck to Union Square Park for display on September 19 and 20 from dawn to dusk. The design chosen as ‘the people’s choice,’ entitled ‘Fractured Bubble’ by Long Island City architects Henry Grosman and Babak Bryan, stood for the requisite seven days of the Jewish holiday of Sukkot. The competition was the brainchild of journalists Joshua Foer and Roger Bennett. It was sponsored by Reboot, an organization that aims to catalyze innovation in Jewish culture, rituals, and traditions.

Edisonade is a modern term, coined in 1993 by John Clute in his and Peter Nicholls’ ‘The Encyclopedia of Science Fiction,’ for fictional stories about a brilliant young inventor and his inventions. This subgenre started in the Victorian and Edwardian eras and had its apex of popularity during the late 19th and early 20th centuries, and was common in ‘scientific romance,’ an archaic term for the genre of fiction now known as ‘science fiction.’
The term ‘Edisonade’ originated in the 1850s to describe both fiction and elements of scientific writing, but has since come to refer to the science fiction of the late nineteenth and early twentieth century, primarily that of Jules Verne, H. G. Wells, and Arthur Conan Doyle. In recent years, the term has come to be applied to science fiction written in a deliberately anachronistic style, as a homage to or pastiche of the original scientific romances.

The X-Seed 4000 is the tallest building ever fully envisioned, meaning that the designs for construction have been completed. Developed by architect Peter Neville, its proposed 4-km height, 6-km wide sea-base, and 800-floor capacity could accommodate 500,000 to 1,000,000 inhabitants. Requiring over 3,000,000 tons of reinforced steel, the construction was estimated to cost US$300–900 billion, in 2006 dollars. It was designed for Tokyo by the Taisei Corporation in 1995 as a futuristic environment combining ultra-modern living and interaction with nature.
Unlike conventional skyscrapers, the X-Seed 4000 would be required to actively protect its occupants from considerable air pressure gradations and weather fluctuations along its massive elevation. Also, the proposed area is situated on the Pacific Ring of Fire, which is the most active volcano range in the world so the structure would be subject to tsunamis and earthquakes. The X-Seed 4000 ‘is never meant to be built,’ says Georges Binder, managing director of Buildings & Data, a firm which compiles data banks on buildings worldwide. ‘The purpose of the plan was to earn some recognition for the firm, and it worked.’
