🔗 Frankenstein Veto
A Frankenstein veto occurs when an American state Governor selectively deletes words from a bill, stitching together the remainder (Ã la Victor Frankenstein) to form a new bill different from that passed by the legislature.
In 2008, the state Constitution of Wisconsin was amended to place certain restrictions on the Frankenstein veto. With those changes, the governor of Wisconsin still has far greater veto powers than any other governor in the United States of America.

🔗 Electro Gyrocator
The Electro Gyro-Cator was claimed to be the world's first automated commercially available automotive navigation system. It was co-developed by Honda, Alpine, and Stanley Electric Co..
Unlike most navigation systems of today, it did not use GPS Satellites to maintain its position and discern movement of the vehicle. Rather, it was an Inertial navigation system, because it contained a helium gas gyroscope that could detect both rotation and movement. A special servo gear was also attached to the transmission housing to feed information to the Gyro-Cator to help maintain position, map speed and distance traveled.
Transparent maps were placed inside the unit and it would scroll them past a 6 inch monochrome CRT illuminated screen as the car traveled along. The monitor would indicate by a series of circles (or cross hairs) on the screen to show the vehicle's current location or display lines for path of travel. A marking pen was also included to help make personal indicators on the map if needed. Adjustments could be made to change the display scale, position, rotation, brightness, and contrast. In its only year of production in 1981, it was announced as an option on that year's Honda Accord and Honda Vigor, but at ¥300,000 ($2,746 USD), it was almost a quarter of the value of the car. It is not clear how many units were actually sold to customers as a "dealer option". A patent for gyroscope design was introduced to the US in design patent D274332.
Documented weight for the unit was roughly 20Â lb (9Â kg). A display unit, with a cutaway of the Gyroscope, is currently shown at the Honda Collection Hall at Twin Ring Motegi, Japan.

🔗 Railway Time
Railway time was the standardised time arrangement first applied by the Great Western Railway in England in November 1840, the first recorded occasion when different local mean times were synchronised and a single standard time applied. The key goals behind introducing railway time were to overcome the confusion caused by having non-uniform local times in each town and station stop along the expanding railway network and to reduce the incidence of accidents and near misses, which were becoming more frequent as the number of train journeys increased.
Railway time was progressively taken up by all railway companies in Great Britain over the following seven years. The schedules by which trains were organised and the time station clocks displayed were brought in line with the local mean time for London or "London Time", the time set at Greenwich by the Royal Observatory, which was already widely known as Greenwich Mean Time (GMT).
The development of railway networks in North America in the 1850s, India in around 1860, and in Europe, prompted the introduction of standard time influenced by geography, industrial development, and political governance.
The railway companies sometimes faced concerted resistance from local people who refused to adjust their public clocks to bring them into line with London Time. As a consequence, two different times would be displayed in the town and in use, with the station clocks and the times published in train timetables differing by several minutes from that on other clocks. Despite this early reluctance, railway time rapidly became adopted as the default time across the whole of Great Britain, although it took until 1880 for the government to legislate on the establishment of a single standard time and a single time zone for the country.
Some contemporary commentators referred to the influence of railway time on encouraging greater precision in daily tasks and the demand for punctuality.

🔗 Appalachian Balds
In the Appalachian Mountains of the eastern United States, balds are mountain summits or crests covered primarily by thick vegetation of native grasses or shrubs occurring in areas where heavy forest growth would be expected.
Balds are found primarily in the Southern Appalachians, where, even at the highest elevations, the climate is too warm to support an alpine zone, areas where trees fail to grow due to short or non-existent growing seasons. The difference between an alpine summit, such as Mount Washington in New Hampshire, and a bald, such as Gregory Bald in the Great Smoky Mountains, is that a lack of trees is normal for the colder climate of the former but abnormal for the warmer climate of the latter. One example of southern balds' abnormality can be found at Roan Mountain, where Roan High Knob (el. 6,285 ft/1,915 m) is coated with a dense stand of spruce-fir forest, whereas an adjacent summit, Round Bald (el. 5,826 ft/1,776 m), is almost entirely devoid of trees. Why some summits are bald and some are not is a mystery, though there are several hypotheses.

🔗 Constraint Programming
Constraint programming (CP) is a paradigm for solving combinatorial problems that draws on a wide range of techniques from artificial intelligence, computer science, and operations research. In constraint programming, users declaratively state the constraints on the feasible solutions for a set of decision variables. Constraints differ from the common primitives of imperative programming languages in that they do not specify a step or sequence of steps to execute, but rather the properties of a solution to be found. In addition to constraints, users also need to specify a method to solve these constraints. This typically draws upon standard methods like chronological backtracking and constraint propagation, but may use customized code like a problem specific branching heuristic.
Constraint programming takes its root from and can be expressed in the form of constraint logic programming, which embeds constraints into a logic program. This variant of logic programming is due to Jaffar and Lassez, who extended in 1987 a specific class of constraints that were introduced in Prolog II. The first implementations of constraint logic programming were Prolog III, CLP(R), and CHIP.
Instead of logic programming, constraints can be mixed with functional programming, term rewriting, and imperative languages. Programming languages with built-in support for constraints include Oz (functional programming) and Kaleidoscope (imperative programming). Mostly, constraints are implemented in imperative languages via constraint solving toolkits, which are separate libraries for an existing imperative language.

🔗 Etymology of tea
The etymology of the word tea can be traced back to the various Chinese pronunciations of the word. Nearly all the words for tea worldwide, fall into three broad groups: te, cha and chai, which reflected the history of transmission of tea drinking culture and trade from China to countries around the world. The few exceptions of words for tea that do not fall into these three broad groups are mostly from the minor languages from the botanical homeland of the tea plant, and likely to be the ultimate origin of the Chinese words for tea. Notably, none of these words mean 'dinner' or a late afternoon meal.

🔗 Wage Slavery - Applicable to [Nearly] Everybody?
Wage slavery is a term describing a situation in which a person's livelihood depends on wages or a salary, especially when the dependence is total and immediate. It has been used to criticise exploitation of labour and social stratification, with the former seen primarily as unequal bargaining power between labour and capital (particularly when workers are paid comparatively low wages, e.g. in sweatshops) and the latter as a lack of workers' self-management, fulfilling job choices and leisure in an economy. The criticism of social stratification covers a wider range of employment choices bound by the pressures of a hierarchical society to perform otherwise unfulfilling work that deprives humans of their "species character" not only under threat of starvation or poverty, but also of social stigma and status diminution. Historically, some socialist organisations and activists have espoused workers' self-management or worker cooperatives as possible alternatives to wage labour.
Similarities between wage labour and slavery were noted as early as Cicero in Ancient Rome, such as in De Officiis. With the advent of the Industrial Revolution, thinkers such as Pierre-Joseph Proudhon and Karl Marx elaborated the comparison between wage labour and slavery, while Luddites emphasised the dehumanisation brought about by machines. The introduction of wage labour in 18th-century Britain was met with resistance, giving rise to the principles of syndicalism. Before the American Civil War, Southern defenders of African American slavery invoked the concept of wage slavery to favourably compare the condition of their slaves to workers in the North. The United States abolished slavery after the Civil War, but labour union activists found the metaphor useful – according to historian Lawrence Glickman, in the Gilded Age "[r]eferences abounded in the labour press, and it is hard to find a speech by a labour leader without the phrase".
