San Francisco the City and County of San Francisco, is the cultural and financial center of Northern California. San Francisco is the 13th-most populous city in the United States, the fourth-most populous in California, with 884,363 residents as of 2017, it covers an area of about 46.89 square miles at the north end of the San Francisco Peninsula in the San Francisco Bay Area, making it the second-most densely populated large US city, the fifth-most densely populated U. S. county, behind only four of the five New York City boroughs. San Francisco is part of the fifth-most populous primary statistical area in the United States, the San Jose–San Francisco–Oakland, CA Combined Statistical Area; as of 2017, it was the seventh-highest income county in the United States, with a per capita personal income of $119,868. As of 2015, San Francisco proper had a GDP of $154.2 billion, a GDP per capita of $177,968. The San Francisco CSA was the country's third-largest urban economy as of 2017, with a GDP of $907 billion.
Of the 500+ primary statistical areas in the US, the San Francisco CSA had among the highest GDP per capita in 2017, at $93,938. San Francisco was ranked 14th in the world and third in the United States on the Global Financial Centres Index as of September 2018. San Francisco was founded on June 29, 1776, when colonists from Spain established Presidio of San Francisco at the Golden Gate and Mission San Francisco de Asís a few miles away, all named for St. Francis of Assisi; the California Gold Rush of 1849 brought rapid growth, making it the largest city on the West Coast at the time. San Francisco became a consolidated city-county in 1856. San Francisco's status as the West Coast's largest city peaked between 1870 and 1900, when around 25% of California's population resided in the city proper. After three-quarters of the city was destroyed by the 1906 earthquake and fire, San Francisco was rebuilt, hosting the Panama-Pacific International Exposition nine years later. In World War II, San Francisco was a major port of embarkation for service members shipping out to the Pacific Theater.
It became the birthplace of the United Nations in 1945. After the war, the confluence of returning servicemen, significant immigration, liberalizing attitudes, along with the rise of the "hippie" counterculture, the Sexual Revolution, the Peace Movement growing from opposition to United States involvement in the Vietnam War, other factors led to the Summer of Love and the gay rights movement, cementing San Francisco as a center of liberal activism in the United States. Politically, the city votes along liberal Democratic Party lines. A popular tourist destination, San Francisco is known for its cool summers, steep rolling hills, eclectic mix of architecture, landmarks, including the Golden Gate Bridge, cable cars, the former Alcatraz Federal Penitentiary, Fisherman's Wharf, its Chinatown district. San Francisco is the headquarters of five major banking institutions and various other companies such as Levi Strauss & Co. Gap Inc. Fitbit, Salesforce.com, Reddit, Inc. Dolby, Weebly, Pacific Gas and Electric Company, Pinterest, Uber, Mozilla, Wikimedia Foundation and Weather Underground.
It is home to a number of educational and cultural institutions, such as the University of San Francisco, University of California, San Francisco, San Francisco State University, the De Young Museum, the San Francisco Museum of Modern Art, the California Academy of Sciences. As of 2019, San Francisco is the highest rated American city on world liveability rankings; the earliest archaeological evidence of human habitation of the territory of the city of San Francisco dates to 3000 BC. The Yelamu group of the Ohlone people resided in a few small villages when an overland Spanish exploration party, led by Don Gaspar de Portolà, arrived on November 2, 1769, the first documented European visit to San Francisco Bay. Seven years on March 28, 1776, the Spanish established the Presidio of San Francisco, followed by a mission, Mission San Francisco de Asís, established by the Spanish explorer Juan Bautista de Anza. Upon independence from Spain in 1821, the area became part of Mexico. Under Mexican rule, the mission system ended, its lands became privatized.
In 1835, Englishman William Richardson erected the first independent homestead, near a boat anchorage around what is today Portsmouth Square. Together with Alcalde Francisco de Haro, he laid out a street plan for the expanded settlement, the town, named Yerba Buena, began to attract American settlers. Commodore John D. Sloat claimed California for the United States on July 7, 1846, during the Mexican–American War, Captain John B. Montgomery arrived to claim Yerba Buena two days later. Yerba Buena was renamed San Francisco on January 30 of the next year, Mexico ceded the territory to the United States at the end of the war. Despite its attractive location as a port and naval base, San Francisco was still a small settlement with inhospitable geography; the California Gold Rush brought a flood of treasure seekers. With their sourdough bread in tow, prospectors accumulated in San Francisco over rival Benicia, raising the population from 1,000 in 1848 to 25,000 by December 1849; the promise of great wealth was so strong that crews on arriving vessels deserted and rushed off to the gold fields, leaving behind a forest of masts in San Francisco harbor.
Some of these 500 abandoned ships were used at times as storeships and hotels.
Web search engine
A web search engine or Internet search engine is a software system, designed to carry out web search, which means to search the World Wide Web in a systematic way for particular information specified in a web search query. The search results are presented in a line of results referred to as search engine results pages; the information may be a mix of web pages, videos, articles, research papers and other types of files. Some search engines mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines maintain real-time information by running an algorithm on a web crawler. Internet content, not capable of being searched by a web search engine is described as the deep web. Internet search engines themselves predate the debut of the Web in December 1990; the Who is user search dates back to 1982 and the Knowbot Information Service multi-network user search was first implemented in 1989. The first well documented search engine that searched content files, namely FTP files was Archie, which debuted on 10 September 1990.
Prior to September 1993, the World Wide Web was indexed by hand. There was a list of webservers hosted on the CERN webserver. One snapshot of the list in 1992 remains, but as more and more web servers went online the central list could no longer keep up. On the NCSA site, new servers were announced under the title "What's New!"The first tool used for searching content on the Internet was Archie. The name stands for "archive" without the "v", it was created by Alan Emtage, Bill Heelan and J. Peter Deutsch, computer science students at McGill University in Montreal, Canada; the program downloaded the directory listings of all the files located on public anonymous FTP sites, creating a searchable database of file names. The rise of Gopher led to two new search programs and Jughead. Like Archie, they searched the file titles stored in Gopher index systems. Veronica provided a keyword search of most Gopher menu titles in the entire Gopher listings. Jughead was a tool for obtaining menu information from specific Gopher servers.
While the name of the search engine "Archie Search Engine" was not a reference to the Archie comic book series, "Veronica" and "Jughead" are characters in the series, thus referencing their predecessor. In the summer of 1993, no search engine existed for the web, though numerous specialized catalogues were maintained by hand. Oscar Nierstrasz at the University of Geneva wrote a series of Perl scripts that periodically mirrored these pages and rewrote them into a standard format; this formed the basis for W3Catalog, the web's first primitive search engine, released on September 2, 1993. In June 1993, Matthew Gray at MIT, produced what was the first web robot, the Perl-based World Wide Web Wanderer, used it to generate an index called'Wandex'; the purpose of the Wanderer was to measure the size of the World Wide Web, which it did until late 1995. The web's second search engine Aliweb appeared in November 1993. Aliweb did not use a web robot, but instead depended on being notified by website administrators of the existence at each site of an index file in a particular format.
JumpStation used a web robot to find web pages and to build its index, used a web form as the interface to its query program. It was thus the first WWW resource-discovery tool to combine the three essential features of a web search engine as described below; because of the limited resources available on the platform it ran on, its indexing and hence searching were limited to the titles and headings found in the web pages the crawler encountered. One of the first "all text" crawler-based search engines was WebCrawler, which came out in 1994. Unlike its predecessors, it allowed users to search for any word in any webpage, which has become the standard for all major search engines since, it was the search engine, known by the public. In 1994, Lycos was launched and became a major commercial endeavor. Soon after, many search engines vied for popularity; these included Magellan, Infoseek, Northern Light, AltaVista. Yahoo! was among the most popular ways for people to find web pages of interest, but its search function operated on its web directory, rather than its full-text copies of web pages.
Information seekers could browse the directory instead of doing a keyword-based search. In 1996, Netscape was looking to give a single search engine an exclusive deal as the featured search engine on Netscape's web browser. There was so much interest that instead Netscape struck deals with five of the major search engines: for $5 million a year, each search engine would be in rotation on the Netscape search engine page; the five engines were Yahoo!, Lycos and Excite. Google adopted the idea of selling search terms in 1998, from a small search engine company named goto.com. This move had a significant effect on the SE business, which went from struggling to one of the most profitable businesses in the Internet. Search engines were known as some of the brightest stars in the Internet investing frenzy that occurred in the late 1990s. Several
Headquarters denotes the location where most, if not all, of the important functions of an organization are coordinated. In the United States, the corporate headquarters represents the entity at the center or the top of a corporation taking full responsibility for managing all business activities. In the United Kingdom, the term head office is most used for the HQs of large corporations; the term is used regarding military organizations. A headquarters is the entity at the top of a corporation that takes full responsibility for the overall success of the corporation, ensures corporate governance; the corporate headquarters is a key element of a corporate structure and covers different corporate functions such as strategic planning, corporate communications, legal, finance, human resources, information technology, procurement. This entity includes the chief executive officer as a key person and his or her support staff such as the CEO office and other CEO-related functions. Many companies have a registered office at a different address to their corporate office.
A headquarters includes the leader of business unit and his or her staff as well as all functions to manage the business unit and operational activities. The head of the business unit is responsible for overall result of the business unit. A headquarters sometimes functions at the top of regional unit, including all activities of the various business units, taking full responsibility for overall profitability and success of this regional unit. Military headquarters take many forms depending on the size and nature of the unit or formation they command, they are split into the forward and rear components, both within NATO nations, those following the organization and doctrine of the former Soviet Union. The forward or tactical HQs is a small group of staff and communicators. Mobile, they exist to allow the commander to go forward in an operation, command the key parts of it from a position where they can see the ground and influence their immediate subordinates; the main HQs is involved in both the planning and execution of operations.
There are a number of staff assembled here from various staff branches to advise the commander, to control the various aspects of planning and the conduct of discrete operations. A main HQ for a large formation will have a chief of staff; the rear or logistic HQs is some distance from the front line in conventional operations. Its function is to ensure the logistical support to front line troops, which it does by organizing the delivery of combat supplies and equipment to where they are needed, by organizing services such as combat medicine, equipment recovery, repair; the headquarters of the Catholic Church is Vatican City. The World Headquarters of Jehovah's Witnesses is relocated in Warwick, New York, from its former location, New York; the headquarters of the Russian Orthodox Church is in Moscow. The World Council of Churches, including Orthodox Churches, has its headquarters in Geneva, Switzerland; the headquarters of Ecumenical Patriarch of Constantinople is located in Turkey. The headquarters of The Church of Jesus Christ of Latter-day Saints is located in Salt Lake City, Utah.
The Anglican Communion Office is in London. In Japanese budō martial arts such as karate, aikido, etc. There is a headquarters for each organization or region; the Japanese word honbu is used for that outside Japan. Sometimes they refer to this headquarters as honbu dojo in which dojo is a facility provided for practicing discipline, the training ground. Sometimes honbu is written as hombu, the way it is pronounced, but according to the Hepburn transcription, the correct spelling should be honbu in which the'n' is a syllabic n. Isby, David C.

A blog is a discussion or informational website published on the World Wide Web consisting of discrete informal diary-style text entries. Posts are displayed in reverse chronological order, so that the most recent post appears first, at the top of the web page; until 2009, blogs were the work of a single individual of a small group, covered a single subject or topic. In the 2010s, "multi-author blogs" emerged, featuring the writing of multiple authors and sometimes professionally edited. MABs from newspapers, other media outlets, think tanks, advocacy groups, similar institutions account for an increasing quantity of blog traffic; the rise of Twitter and other "microblogging" systems helps integrate MABs and single-author blogs into the news media. Blog can be used as a verb, meaning to maintain or add content to a blog; the emergence and growth of blogs in the late 1990s coincided with the advent of web publishing tools that facilitated the posting of content by non-technical users who did not have much experience with HTML or computer programming.
A knowledge of such technologies as HTML and File Transfer Protocol had been required to publish content on the Web, early Web users therefore tended to be hackers and computer enthusiasts. In the 2010s, the majority are interactive Web 2.0 websites, allowing visitors to leave online comments, it is this interactivity that distinguishes them from other static websites. In that sense, blogging can be seen as a form of social networking service. Indeed, bloggers do not only produce content to post on their blogs, but often build social relations with their readers and other bloggers. However, there are high-readership blogs. Many blogs provide commentary on topic, ranging from politics to sports. Others function as more personal online diaries, others function more as online brand advertising of a particular individual or company. A typical blog combines text, digital images, links to other blogs, web pages, other media related to its topic; the ability of readers to leave publicly viewable comments, interact with other commenters, is an important contribution to the popularity of many blogs.
However, blog owners or authors moderate and filter online comments to remove hate speech or other offensive content. Most blogs are textual, although some focus on art, videos and audio. In education, blogs can be used as instructional resources; these blogs are referred to as edublogs. Microblogging is another type of blogging, featuring short posts. On 16 February 2011, there were over 156 million public blogs in existence. On 20 February 2014, there were around 172 million Tumblr and 75.8 million WordPress blogs in existence worldwide. According to critics and other bloggers, Blogger is the most popular blogging service used today. However, Blogger does not offer public statistics. Technorati lists 1.3 million blogs as of February 22, 2014. The term "weblog" was coined by Jorn Barger on 17 December 1997; the short form, "blog", was coined by Peter Merholz, who jokingly broke the word weblog into the phrase we blog in the sidebar of his blog Peterme.com in April or May 1999. Shortly thereafter, Evan Williams at Pyra Labs used "blog" as both a noun and verb and devised the term "blogger" in connection with Pyra Labs' Blogger product, leading to the popularization of the terms.
Before blogging became popular, digital communities took many forms including Usenet, commercial online services such as GEnie, Byte Information Exchange and the early CompuServe, e-mail lists, Bulletin Board Systems. In the 1990s, Internet forum software created running conversations with "threads". Threads are topical connections between messages on a virtual "corkboard". From 14 June 1993, Mosaic Communications Corporation maintained their "What’s New" list of new websites, updated daily and archived monthly; the page was accessible by a special ``. The earliest instance of a commercial blog was on the first business to consumer Web site created in 1995 by Ty, Inc. which featured a blog in a section called "Online Diary". The entries were maintained by featured Beanie Babies that were voted for monthly by Web site visitors; the modern blog evolved from the online diary where people would keep a running account of the events in their personal lives. Most such writers journalers. Justin Hall, who began personal blogging in 1994 while a student at Swarthmore College, is recognized as one of the earlier bloggers, as is Jerry Pournelle.
Dave Winer's Scripting News is credited with being one of the older and longer running weblogs. The Australian Netguide magazine maintained the Daily Net News on their web site from 1996. Daily Net News ran links and daily reviews of new websites in Australia. Another early blog was Wearable Wireless Webcam, an online shared diary of a person's personal life combining text, digital video, digital pictures transmitted live from a wearable computer and EyeTap device to a web site in 1994; this practice of semi-automated blogging with live video together with text was referred to as sousveillance, such journals were used as evidence in legal matters. Some early bloggers, such as The Misanthropic Bitch, who began in 1997 referred to their online presence as a zine, before the term blog entered common usage. Early blogs were manually updated components of common Websites. In 1995, the "Online Diary" on
Technology is the collection of techniques, skills and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques and the like, or it can be embedded in machines to allow for operation without detailed knowledge of their workings. Systems applying technology by taking an input, changing it according to the system's use, producing an outcome are referred to as technology systems or technological systems; the simplest form of technology is the use of basic tools. The prehistoric discovery of how to control fire and the Neolithic Revolution increased the available sources of food, the invention of the wheel helped humans to travel in and control their environment. Developments in historic times, including the printing press, the telephone, the Internet, have lessened physical barriers to communication and allowed humans to interact on a global scale. Technology has many effects, it has allowed the rise of a leisure class.
Many technological processes produce unwanted by-products known as pollution and deplete natural resources to the detriment of Earth's environment. Innovations have always influenced the values of a society and raised new questions in the ethics of technology. Examples include the rise of the notion of efficiency in terms of human productivity, the challenges of bioethics. Philosophical debates have arisen over the use of technology, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, similar reactionary movements criticize the pervasiveness of technology, arguing that it harms the environment and alienates people; the use of the term "technology" has changed over the last 200 years. Before the 20th century, the term was uncommon in English, it was used either to refer to the description or study of the useful arts or to allude to technical education, as in the Massachusetts Institute of Technology; the term "technology" rose to prominence in the 20th century in connection with the Second Industrial Revolution.
The term's meanings changed in the early 20th century when American social scientists, beginning with Thorstein Veblen, translated ideas from the German concept of Technik into "technology." In German and other European languages, a distinction exists between technik and technologie, absent in English, which translates both terms as "technology." By the 1930s, "technology" referred not only to the study of the industrial arts but to the industrial arts themselves. In 1937, the American sociologist Read Bain wrote that "technology includes all tools, utensils, instruments, clothing and transporting devices and the skills by which we produce and use them." Bain's definition remains common among scholars today social scientists. Scientists and engineers prefer to define technology as applied science, rather than as the things that people make and use. More scholars have borrowed from European philosophers of "technique" to extend the meaning of technology to various forms of instrumental reason, as in Foucault's work on technologies of the self.
Dictionaries and scholars have offered a variety of definitions. The Merriam-Webster Learner's Dictionary offers a definition of the term: "the use of science in industry, etc. to invent useful things or to solve problems" and "a machine, piece of equipment, etc., created by technology." Ursula Franklin, in her 1989 "Real World of Technology" lecture, gave another definition of the concept. The term is used to imply a specific field of technology, or to refer to high technology or just consumer electronics, rather than technology as a whole. Bernard Stiegler, in Technics and Time, 1, defines technology in two ways: as "the pursuit of life by means other than life," and as "organized inorganic matter."Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems, it is a far-reaching term that may include simple tools, such as a crowbar or wooden spoon, or more complex machines, such as a space station or particle accelerator.
Tools and machines need not be material. W. Brian Arthur defines technology in a broad way as "a means to fulfill a human purpose."The word "technology" can be used to refer to a collection of techniques. In this context, it is the current state of humanity's knowledge of how to combine resources to produce desired products, to solve problems, fulfill needs, or satisfy wants; when combined with another term, such as "medical technology" or "space technology," it refers to the state of the respective field's knowledge and tools. "State-of-the-art technology" refers to the high technology available to humanity in any field. Technology can be viewed as an activity that changes culture. Additionally, technology is the application of math, science, an
