Foursquare Day

Foursquare Day takes place annually on 16 April, April being the 4th month and the 16th being equal to four squared. Foursquare is a local search-and-discovery service mobile app which provides search results for its users. The app provides personalized recommendations of places to go to near a user’s current location based on users’ “previous browsing history, purchases, or check-in history”.

Some cities have made official proclamations of April 16 being Foursquare Day (Istanbul, Turkey; Atlanta, Georgia; Austin, Texas; Cincinnati, Ohio; Corpus Christi, Texas; Gaithersburg, Maryland; Indianapolis, Indiana; Kalamazoo, Michigan; Kennesaw, Georgia; Manchester, New Hampshire; New York City; Portsmouth, New Hampshire; Santo Domingo, Dominican Republic; Seattle, Washington; Miami, Florida; Victoria, British Columbia, Canada; Toronto, Ontario, Canada; Ramat Hasharon, Israel; Singapore). Foursquare Day was coined by Nate Bonilla-Warford, an optometrist from Tampa, Florida on March 12, 2010. The idea came to him while “thinking about new ways to promote his business”.

Foursquare was created in late 2008 and launched in 2009 by Dennis Crowley and Naveen Selvadurai. Crowley had previously founded the similar project Dodgeball as his graduate thesis project in the Interactive Telecommunications Program (ITP) at New York University. Google bought Dodgeball in 2005 and shut it down in 2009, replacing it with Google Latitude. Dodgeball user interactions were based on SMS technology, rather than an application. Foursquare was the second iteration of that same idea, that people can use mobile devices to interact with their environment. Foursquare was Dodgeball reimagined to take advantage of the new smartphones, like the iPhone, which had built in GPS to better detect a user’s location.

Until late July 2014, Foursquare featured a social networking layer that enabled a user to share their location with friends, via the “check in” – a user would manually tell the application when they were at a particular location using a mobile website, text messaging, or a device-specific application by selecting from a list of venues the application locates nearby. In May 2014, the company launched Swarm, a companion app to Foursquare, that reimagined the social networking and location sharing aspects of the service as a separate application. On August 7, 2014 the company launched Foursquare 8.0, the completely new version of the service which finally removed the check in and location sharing entirely, to focus entirely on local search.

As of December 2013, Foursquare reported 45 million registered users, though many of these will not be active users. Male and female users are equally represented and also 50 percent of users are outside the US. Support for French, Italian, German, Spanish, and Japanese was added in February 2011. Support for Indonesian, Korean, Portuguese, Russian, and Thai was added in September 2011. Support for Turkish was added in June 2012. On January 14, 2016, Co-founder Dennis Crowley, stepped down from his position as CEO. He moved to an Executive Chairman position while Jeff Glueck, the company’s COO, succeeded Crowley as the new CEO.

In 2010 McDonald’s launched a spring pilot program that took advantage of Foursquare Day. Foursquare users who checked into McDonald’s restaurants on Foursquare Day were given the chance to win gift cards in 5 and 10 dollar increments. Mashable reported that there was a “33% increase in foot traffic” to McDonald’s venues, as apparent in the increase in Foursquare check-ins.

National Mario Day

National Mario Day takes place annually on March 10, (as the date MAR 10 resembles the name MARIO). Mario (マリオ) is a fictional character in the Mario video game franchise, owned by Nintendo and created by Japanese video game designer Shigeru Miyamoto who created Mario while developing Donkey Kong in an attempt to produce a best-selling video game for Nintendo. Originally, Miyamoto wanted to create a video game that used the characters Popeye, Bluto, and Olive Oyl At the time, however, Miyamoto was unable to acquire a license to use the characters (and would not until 1982 with Popeye), so he ended up making an unnamed player character’ which became Mario alongside, Donkey Kong, and Lady (later known as Pauline).

Mario is Depicted as a short, pudgy, Italian plumber who resides in the Mushroom Kingdom, his adventures generally center upon rescuing Princess Peach from the Koopa villain Bowser. His younger brother and sidekick is Luigi. The Mario franchise is the best-selling video game franchise of all time. Mario has appeared in over 200 video games since his creation. Outside of the Super Mario platform series, other Mario genres include the Mario Kart racing series, sports games such as the Mario Tennis and Mario Golf series, role-playing games such as Super Mario RPG and Paper Mario, and educational games such as Mario Is Missing!, Mario’s Time Machine and Mario Teaches Typing. Mario has also appeared in television shows, film, comics, and licensed merchandise. Since 1990, Mario has been voiced by Charles Martinet.

Mario was originally named Jumpman in the game’s English instructions and Mario in the sales brochure. Miyamoto originally named the character “Mr. Video” he was eventually named Mario after American warehouse landlord Mario Segale who owned the premesis where Nintendo was based, when he confronted then-president Minoru Arakawa, demanding back rent. Following a heated argument, the Nintendo employees eventually convinced Segale he would be paid, and opted to name the character in the game Mario after him.

Mario’s profession was chosen to fit with the game design. Since Donkey Kong was set on a construction site, Mario was made into a carpenter. When he appeared again in Mario Bros., it was decided he should be a plumber, since a lot of the game is played in underground settings. Mario’s appearance was dictated in part by the graphical limitations of arcade hardware at the time, Miyamoto clothed the character in red overalls and a blue shirt to contrast against each other and the background and added A red cap. Over time, Mario’s appearance has become more defined; blue eyes, white gloves, brown shoes, a red “M” in a white circle on the front of his hat and gold buttons on his overalls have been added. The colors of his shirt and overalls were also reversed from a blue shirt with red overalls to a red shirt with blue overall. Then To make him appear human onscreen despite his small size, Mario was given distinct features, prominently a large nose and a mustache, which avoided the need to draw a mouth and facial expressions. Nintendo did not initially reveal Mario’s full name. However Miyamoto eventually confirmed that his name was indeed Mario Mario at the September 2015 at the Super Mario Bros. 30th Anniversary festival.

Data Privacy Day

Data Privacy Day takes place annually on January 28. The purpose of Data Privacy Day (Data Protection Day in Europe) is to raise awareness and promote privacy and data protection best practices. It is currently ‘celebrated’ in the United States, Canada, and 27 European countries. In Europe it is referred to as Data Protection Day.

Data Privacy Day’s educational initiative originally focused on raising awareness among businesses as well as users about the importance of protecting the privacy of their personal information online, particularly in the context of social networking. The educational focus has expanded over the past four years to include families, consumers and businesses. In addition to its educational initiative, Data Privacy Day promotes events and activities that stimulate the development of technology tools that promote individual control over personally identifiable information; encourage compliance with privacy laws and regulations; and create dialogues among stakeholders interested in advancing data protection and privacy. The international celebration offers many opportunities for collaboration among governments, industry, academia, nonprofits, privacy professionals and educators.

The Convention for the Protection of Individuals with regard to Automatic Processing of Personal Data was opened by the Council of Europe in 1981. This convention is currently in the process of being updated in order to reflect new legal challenges caused by technological development. The Convention on Cybercrime is also protecting the integrity of data systems and thus of privacy in cyberspace. Privacy including data protection is also protected by Article 8 of the European Convention on Human Rights.

The day was initiated by the Council of Europe in 2007 as the European Data Protection Day and on January 26, 2009, the United States House of Representatives passed a House Resolution declaring January 28 National Data Privacy Day. On January 28, 2009, the Senate officially recognised January 28, 2009 as National Data Privacy Day. In response to the increasing levels of data breaches and the global importance of privacy and data security, the Online Trust Alliance (OTA) and the National Cyber Security Alliance adopted Data Privacy Day as Data Privacy & Protection Day, emphasizing the need to look at the long-term impact to consumers of data collection, use and protection practices and they also organise other Data Protection Day Activities

Charles Babbage FRS

Mathematician, philosopher, inventor and mechanical engineer and English Polymath Charles Babbage, FRS was born 26 December 1791. Babbage attended country school inAlphington near Exeter, then attended King Edward VI Grammar School in Totnes, South Devon, but his health forced him back to private tutors for a time Babbage then joined Holmwood academy, in Baker Street, Enfield,Middlesex, The academy’s library kindled Babbage’s love of mathematics. He studied with two more private tutors after leaving the academy. He was brought home, to study at the Totnes school: Babbage was accepted by Cambridge University and arrived at Trinity College, Cambridge, in October 1810, where he formed the Analytical society in 1812 with John Herschel and George Peacock ; Babbage was also a member of The Ghost Club, which investigated supernatural phenomena, and the Extractors Club, dedicated to liberating its members from the madhouse, should any be committed to one .In 1812 Babbage transferred to Peterhouse, Cambridge. He was the top mathematician there, but did not graduate with honours, receiving a degree without examination instead in 1814 after having defended a thesis that was considered blasphemous in the preliminary public disputation;

In 1815 Babbage lectured at the Royal Institution on astronomy and was elected a Fellow of the Royal Society in 1816. After graduation, Babbage and Herschel visited the Society of Arcueil in Paris, meeting leading French mathematicians and physicists and also worked on a basic explanation of the Electrodynamics of Arago’s rotation with Herschel, and Michael Farraday. These are now part of the theory of eddy currents. He also worked on the unification of electromagnetics. Babbage was also interested in the Coarative View of the Various institutions for the Assurance of Lives and calculated Acturial tables for an insurance Company using Equitable Society Mortality Data from 1762. Babbage helped found the Astronomical Society in 1820, whose aims were to reduce astronomical calculations to a more standard form, and publish the data. In 1824 Babbage won the Astronomical Society’s Gold Medal, “for his invention of an engine for calculating mathematical and astronomical tables” to overcome errors made in tables by mechanisation and to improve the Nautical Almanac after decrepencies were found in traditional calculations. Babbage also helped establish a modern postal system, with his friend Thomas Frederick Colby, And introduced the Uniform Fourpenny Post supplanted by the Uniform Penny Post. In 1816 Babbage, Herschel and Peacock published a translation from French of the lectures of Sylvestre Lacroix concerning Calculus, the Formal Power Series which affected functional equations (including the difference equations fundamental to the difference engine) and operator (D-module) methods for differential equations. He also originated the concept of a programmable computer” and invented the first mechanical computer that eventually led to more complex designs.

The analogy of difference and differential equations was notationally changing Δ to D, as a “finite” difference becomes “infinitesimal”. These symbolic directions became popular, as operational calculus, and pushed to the point of diminishing returns. Woodhouse had already founded this second “British Lagrangian School” Babbage worked intensively on functional equations in general, influenced by Arbogast’s ideas. From 1828 to 1839 Babbage was Lucasian Professor of Mathematics at Cambridge. Not a conventional resident don, and inattentive to teaching, he wrote three topical books during this period of his life. He was elected a Foreign Honorary Member of theAmerican Academy of Arts and Sciences in 1832. Babbage planned to lecture in 1831 on political economy. Babbage’s reforming direction Aiming to make university education more inclusive, with universities doing more for research, a broader syllabus and more interest in applications, but the idea was rejected. Another controversy Babbage had with Richard Jones lasted for six years and he never gave another lecture. Babbage also tried to enter politics, his views included disestablishment of the Church of England, a broader political franchise, and inclusion of manufacturers as stakeholders. He twice stood for Parliament as a candidate for the borough of Finsbury. In 1832 he came in third among five candidates, missing out by some 500 votes in the two-member constituency when two other reformist candidates, Thomas Wakley and Christopher Temple, split the vote. Babbage wrote another book Reflections on the Decline of Science and some of its Causes (1830) attacking the establishment and aiming to improve British science, by ousting Davies Gilbert as President of the Royal Society. Babbage also wished to become the junior secretary of the Royal Society, as Herschel was the senior, but failed after antagonizing Humphry Davy. subsequently the British Association for the Advancement of Science (BAAS) was formed in 1831.

Babbage used symbols to express the actions of his Difference and Analytical Engines in his influential book Economy of Machinery and Manufactures, which dealt with the organisation of industrial production. And An essay on the general principles which regulate the application of machinery to manufactures and the mechanical arts, was featured in the Encyclopædia Metropolitana. In his book Babbage developed the schematic classification of machines, whether for Domestic or industrial use andThe book also contained ideas on rational design in factories, and profit sharing and described The Babbage Principal. This discussed the commercial advantages available with more careful division of labour This principal had already been mentioned in the work of Melchiorre Gioia in 1815.The term was introduced in 1974 by Harry Braverman. Related formulations are the “principle of multiples” of Philip Sargant Florence, and the “balance of processes”. Babbage noticed that skilled workers typically spend parts of their time performing tasks that are below their skill level. If the labour process can be divided among several workers, labour costs may be cut by assigning only high-skill tasks to high-cost workers, restricting other tasks to lower-paid workers And that apprenticeship can be taken as fixed cost but returns to scale are available favoring the factory system. He also published a detailed breakdown of the cost structure of book publishing exposing the trade’s profitability,much to the chagrin of many publishers and namedthe organisers of the trade’s restrictive practices.

Babbage’s theories also influenced the 1851 Great Exhibition his views having a strong effect on many. Karl Marx argued that the source of the productivity of the factory system was the combination of the division of labour with machinery but mentioned that the motivation for division of labour was often for the sake of profitability, rather than productivity. Babbage also influenced the economic thinking of John Stuart Mill, George Holyoake, the economist Claude Lucien Bergery, William Jevons and Charles Fourier among others

In 1837, Babbage published On the Power, Wisdom and Goodness of God. A work of natural theology in which Babbage favored uniformitarianism preferring the conception of creation in which natural law dominated, removing the need for “contrivance. It incorporated extracts from related correspondence of Herschel withCharles Lyell. Babbage put forward the thesis that God had the omnipotence and foresight to create as a divine legislator. He could make laws which then produced species at the appropriate times, rather than continually interfering with ad hoc miracles each time a new species was required. The British Association as inspired by the Deutsche Naturforscher-Versammlung, founded in 1822. It rejected romantic science as well as metaphysics, and started to entrench the divisions of science from literature, and professionals from amateurs. Babbage also identified closely with industrialists And Suggested that industrial society was the culmination of human development. In 1838 a clash with Roderick Murchison led to his withdrawal from further involvement and he also resigned as Lucasian professor,

His interests became more focussed, on computation and metrology, and on international contacts And announced A project to tabulate all physical constants (referred to as “constants of nature”, a phrase in itself a neologism), and then to compile an encyclopedic work of numerical information. He was a pioneer in the field of “absolute measurement”.] His ideas followed on from those of Johann Christian Poggendorff, and were mentioned to Brewster in 1832. There were to be 19 categories of constants, and Ian Hacking sees these as reflecting in part Babbage’s “eccentric enthusiasms” Babbage’s paper On Tables of the Constants of Nature and Art was reprinted by the Smithsonian Institution in 1856, with an added note that the physical tables of Arnold Henry Guyot “will form a part of the important work proposed in this article”.Exact measurement was also key to the development of machine tools. Here again Babbage is considered a pioneer, with Henry Maudslay, William Sellers, and Joseph Whitworth

Babbage also met the the Engineers Marc Brunel and Joseph Clement at the Royal Society And introduced them to Isambard Kingdom Brunel in 1830, for a contact with the proposed Bristol & Birmingham Railway. He also carried out studies, around 1838, showing the superiority of the broad gauge for railways, used by Brunel’s Great Western Railway ln 1838, And invented the pilot (also called a cow-catcher), the metal frame attached to the front of locomotives that clears the tracks of obstacles; he also constructed a dynamometer car. His eldest son, Benjamin Herschel Babbage, also worked as an engineer for Brunel on the railways before emigrating to Australia in the 1850s. Babbage also invented an ophthalmoscope, however the optician Thomas Wharton Jones, ignored it and It Was only widely used after being independently invented by Hermann von Helmholtz.

Babbage also decoded Vigenère’s autokey cipher during the Crimean War His discovery being kept a military secret And later wrote a letter anonymously to the Journal of the Society for Arts concerning “Cypher Writing” . Babbage lived and worked for over 40 years at 1 Dorset Street, Marylebone, where he died, at the age of 79, on 18 October 1871; he was buried in London’s Kensal Green Cemetery. According to Horsley, Babbage died “of renal inadequacy, secondary to cystitis.” He had declined both a knighthood and baronetcy. He also argued against hereditary peerages, favoring life peerages instead .In 1983 the autopsy report for Charles Babbage was discovered and later published by his great-great-grandson A copy of the original is also available. Half of Babbage’s brain is preserved at the Hunterian Museum in the Royal College of Surgeons in London The other half of Babbage’s brain is on display in the Science Museum, London.

Ada lovelace

The Analyst, Metaphysician, and Founder of Scientific Computing, Augusta Ada King, Countess of Lovelace was born on 10th December 1815. Born Augusta Ada Byron and now commonly known as Ada Lovelace, she was the daughter of Lord Byron and is remembered as a mathematician and writer chiefly known for her work on Charles Babbage’s early mechanical general-purpose computer, the Analytical Engine. Her notes on the engine include what is recognised as the first algorithm intended to be processed by a machine. Because of this, she is often considered the world’s first computer programmer and left a legacy as role model for young women entering technology careers.

Ada was the only legitimate child born during a brief marriage between the poet Lord Byron and Anne Isabella Byron). She had no relationship with her father, who separated from her mother just a month after Ada was born, and four months later he left England forever and died in Greece in 1823 leaving her mother to raise her single-handedly, Her life was an apotheosis of struggle between emotion and reason, subjectivism and objectivism, poetics and mathematics, ill health and bursts of energy. Lady Byron wished her daughter to be unlike her poetical father, and she saw to it that Ada received tutoring in mathematics and music, as disciplines to counter dangerous poetic tendencies. But Ada’s complex inheritance became apparent as early as 1828, when she produced the design for a flying machine. It was mathematics that gave her life its wings.

As a young adult, she took an interest in mathematics, and in particular that of Lucasian professor of mathematics at Cambridge, Charles Babbage whom she met met in 1833, when she was just 17, who was One of the gentlemanly scientists of the era and become Ada’s lifelong friend. Babbage, was known as the inventor of the Difference Engine, an elaborate calculating machine that operated by the method of finite differences , and they began a voluminous correspondence on the topics of mathematics, logic, and ultimately all subjects. In 1835, Ada married William King, ten years her senior, and when King inherited a noble title in 1838, they became the Earl and Countess of Lovelace. Ada had three children. The family and its fortunes were very much directed by Lady Byron, whose domineering was rarely opposed by King.Babbage had made plans in 1834 for a new kind of calculating machine (although the Difference Engine was not finished), an Analytical Engine.

His Parliamentary sponsors refused to support a second machine with the first unfinished, but Babbage found sympathy for his new project abroad. In 1842, an Italian mathematician, Louis Menebrea, published a memoir in French on the subject of the Analytical Engine. Babbage enlisted Ada as translator for the memoir, and during a nine-month period in 1842-43, she worked feverishly on the article and a set of Notes she appended to it. These notes contain what is considered the first computer program — that is, an algorithm encoded for processing by a machine. Ada’s notes are important in the early history of computers. She also foresaw the capability of computers to go beyond mere calculating or number-crunching while others, including Babbage himself, focused only on these capabilities

Ada called herself an Analyst (& Metaphysician), and the combination was put to use in the Notes. She understood the plans for the device as well as Babbage but was better at articulating its promise. She rightly saw it as what we would call a general-purpose computer. It was suited for “developing and tabulating any function whatever. . . the engine is the material expression of any indefinite function of any degree of generality and complexity.” Her Notes anticipate future developments, including computer-generated music.

Ada Lovelace sadly passed away on November 27, 1852, in Marylebone at the age of 37, from Cancer and was buried beside the father she never knew. Her contributions to science were resurrected only recently, but many new biographies* attest to the fascination of Babbage’s “Enchantress of Numbers.” And her immense contribution to Maths, Metaphysics, science and modern computers has finally been recognised.

Bill Gates

American business magnate, software executive and philanthropist William Henry “Bill” Gates III was born October 28th, 1955. Bill Gates is the former chief executive and current chairman of Microsoft, the world’s largest personal-computer software company, which he co-founded with Paul Allen. He is consistently ranked among the world’s wealthiest people and was the wealthiest overall from 1995 to 2009, excluding 2008, when he was ranked third; in 2011 he was the third wealthiest American and the second wealthiest person. During his career at Microsoft, Gates held the positions of CEO and chief software architect, and remains the largest individual shareholder, with 6.4 percent of the common stock. He has also authored or co-authored several books.Gates is one of the best-known entrepreneurs of the personal computer revolution. Gates has been criticized for his business tactics, which have been considered anti-competitive, an opinion which has in some cases been upheld by the courts. In the later stages of his career, Gates has pursued a number of philanthropic endeavors, donating large amounts of money to various charitable organizations and scientific research programs through the Bill & Melinda Gates Foundation, established in 2000.

Gates stepped down as chief executive officer of Microsoft in January 2000. He remained as chairman and created the position of chief software architect. In June 2006, Gates announced that he would be transitioning from full-time work at Microsoft to part-time work, and full-time work at the Bill & Melinda Gates Foundation. He gradually transferred his duties to Ray Ozzie, chief software architect, and Craig Mundie, chief research and strategy officer. Gates’s last full-time day at Microsoft was June 27, 2008.
