A Short History of Microsoft

A Short History of Microsoft Microsoft Corp. is an American technology company headquartered in Redmond, Washington, that supports the invention, manufacturing, and licensing of goods and services related to computing. It was registered in New Mexico in 1976 after being formed the year before by two childhood friends. Two Computer Geeks Before Paul Allen and Bill Gates co-founded Microsoft, they were avid computer geeks in an age when access to computers was hard to come by. Allen and Gates skipped high school classes to live and breathe in their schools computer room. Eventually, they hacked the schools computer and were caught, but instead of being expelled, they was offered unlimited computer time in exchange for helping to improve the school computers performance. Gates and Allen ran their own small company, called Traf-O-Data, while in high school and sold a computer to the city of Seattle for counting city traffic.

However, Gates first love never left him  as he spent most of his time in Harvards computer center, where he kept improving his programming skills. Soon Allen moved to Boston as well, working as a programmer and pressuring Gates to quit Harvard so they could work full time together on their projects. Gates was uncertain of what to do, but fate stepped in. The Birth of Microsoft In January 1975, Allen read an article in Popular Electronics magazine about the Altair 8800 microcomputer and showed it to Gates. Gates called MITS, makers of the Altair, and offered his and Allens services to write a version of the new BASIC programming language for the Altair. After eight weeks, Allen and Gates demonstrated their program to MITS, which agreed to distribute and market the product under the name of Altair BASIC. The Altair deal inspired Gates and Allen to form their own software company. Microsoft was started on April 4, 1975, in Albuquerque, New Mexico, the home of MITS, with Gates as the first CEO. Where the Name Microsoft Came From On July 29, 1975, Gates used the name Micro-Soft, which had been suggested by Allen, in a letter to Allen referring to their partnership. The name, a portmanteau of microcomputer and software, was registered with the New Mexico secretary of state on Nov. 26, 1976. In August 1977, the company opened its first international office in Japan, called ASCII Microsoft. In 1979, the company moved to Bellevue, Washington, and two years later incorporated there under the name Microsoft Inc. Gates was president of the company and chairman of the board and Allen was executive vice president. History of Microsoft Products MicrosoftOperating Systems An operating system is a fundamental software that allows a computer to operate. As a newly formed company, Microsofts first operating system product to be publicly released was a version of Unix called Xenix, released in 1980. Xenix was later used as the basis for Microsofts first word processor, called Multi-Tool Word, a predecessor to Microsoft Word. Microsofts first wildly successful operating system was MS-DOS or Microsoft Disk Operating System, which Microsoft wrote for IBM in 1981 based on computer programmer Tim Patersons QDOS. In the deal of the century, Gates licensed MS-DOS to IBM but retained rights to the software. Gates made a fortune for Microsoft, which had become a major soft vendor. Microsoft Mouse Microsofts mouse was released on May 2, 1983. Windows Also in 1983, Microsofts crowning achievement was released. The  Microsoft Windows operating system had a novel graphical user interface and a multitasking environment for IBM computers. In 1986, the company went public, and Gates became a billionaire at 31. Microsoft Office 1989 marked the release of Microsoft Office, a software package that, as the name describes, is a collection of programs for use in an office. It includes a word processor, spreadsheet, mail program, business presentation software, and more. Internet Explorer In August 1995, Microsoft released Windows 95, which included technologies for connecting to the Internet, such as built-in support for dial-up networking, TCP/IP (Transmission Control Protocol/Internet Protocol), and the web browser Internet Explorer 1.0. Xbox In 2001, Microsoft introduced its first gaming unit, the Xbox system. Xbox faced stiff competition from Sonys PlayStation, and eventually Microsoft discontinued the original Xbox in favor of later versions. In 2005, Microsoft released the Xbox 360 gaming console, which was a success. Microsoft Surface In 2012, Microsoft made its first foray into the computing hardware market with the announcement of Surface tablets that ran Windows RT and Windows 8 Pro.

A Timeline and History of the Olmec Civilization

A Timeline and History of the Olmec Civilization Olmec: An Introduction The Olmec civilization is the name given to a sophisticated central American culture with its heyday between 1200 and 400 BC. The Olmec heartland lies in the Mexican states of Veracruz and Tabasco, at the narrow part of Mexico west of the Yucatan peninsula and east of Oaxaca. The following is an introductory guide to the Olmec civilization, its place in Central American prehistory, and some important facts about the people and how they lived. Olmec Timeline Initial Formative: 1775-1500 cal BCEarly Formative: 1450-1005 cal BCMiddle Formative: 1005-400 cal BCLate Formative: 400 cal BC While the very earliest sites of the Olmec show relatively simple egalitarian societies based on hunting and fishing, the Olmecs eventually established a highly complex level of political government, including public building projects such as pyramids and large platform mounds; agriculture; a writing system; and a characteristic sculptural artistry including enormous stone heads with heavy features reminiscent of angry babies. Olmec Capitals There are four main regions or zones that have been associated with Olmec by the use of iconography, architecture and settlement plan, including  San Lorenzo de Tenochtitlan,  La Venta, Tres Zapotes, and Laguna de los Cerros. Within each of these zones, there were three or four different levels of hamlets of different sizes. At the center of the zone was a fairly dense center with plazas and  pyramids  and kingly residences. Outside of the center were a somewhat sparser collection of hamlets and farmsteads, each at least economically and culturally tied to the center. Olmec Kings and Rituals Although we dont know any of the Olmec king names, we do know that the rituals associated with king included an emphasis on the sun and reference to solar equinoxes were built into platform and plaza configurations. Sun glyph iconography is seen on many locations and there is an undeniable importance of  sunflower  in dietary and ritual contexts. The ballgame played an important role in  Olmec culture, as it does in many central American societies, and, like those other societies, it may have included human sacrifice. The colossal heads are often sculpted with headgear, thought to represent ball player wear; animal effigies exist of jaguars dressed as ball players. It is possible that women also played in the games, as there are figurines from  La Venta  which are females wearing helmets. Olmec Landscape The Olmec farms and hamlets and centers were situated on and next to a diverse set of landforms, including floodplain lowlands, coastal plains, plateau uplands, and volcanic highlands. But the large Olmec capitals were based on high places in the  floodplains  of big rivers such as Coatzacoalcos and Tabasco. The Olmec coped with recurring floods by building their residences and storage structures on artificially raised earth platforms, or by rebuilding on old sites, creating tell formations. Many of the earliest Olmec sites are likely buried deep within the floodplains. The Olmec were clearly interested in color and color schemes of the environment. For example, the plaza at  La Venta  has a striking appearance of brown soil embedded with tiny bits of shattered greenstone. And there are several blue-green serpentine mosaic pavements tiled with clays and sands in a rainbow of different colors. A common sacrificial object was a jadeite offering covered with red  cinnabar. Olmec Diet and Subsistence By 5000 BC, the Olmec relied on  domestic maize,  sunflower, and manioc, later domesticating  beans. They also gathered corozo palm nuts, squash, and  chili. There is some possibility that the Olmec were the first to use  chocolate. The main source of animal protein was domesticated  dog  but that was supplemented with white-tailed deer, migratory birds, fish, turtles, and coastal shellfish. White tailed-deer, in particular, was specifically associated with ritual feasting. Sacred places:  Caves (Juxtlahuaca and Oxtotitln), springs, and mountains. Sites: El Manati, Takalik Abaj, Pijijiapan. Human Sacrifice:  Children and infants at  El Manati; human remains under monuments at  San Lorenzo;  La Venta  has an altar showing an eagle-clad king holding a captive. Bloodletting, ritual cutting of part of the body to allow bleeding for sacrifice, was probably also practiced. Colossal Heads:  Appear to be portraits of male (and possibly female) Olmec rulers. Sometimes wear helmets indicating that they are ballplayers, figurines, and sculpture from  La Venta  show that women wore helmet headgear, and some of the heads may represent women. A relief at the Pijijiapan as well as  La Venta  Stela 5 and La Venta Offering 4 show women standing next to men rulers, perhaps as partners. Olmec Trade, Exchange, and Communications Exchange:  Exotic materials were brought in or traded from far places to  the Olmec  zones, including literally tons of volcanic basalt to  San Lorenzo  from the Tuxtla mountains, 60 km away, which was carved into royal sculptures and  manos  and metates, natural basalt columns from Roca Partida. Greenstone (jadeite, serpentine, schist, gneiss, green quartz), played a clearly important role in elite contexts at Olmec sites. Some sources for these materials are the gulf coastal region in Motagua Valley, Guatemala, 1000 km away from the Olmec heartland. These materials were carved into beads and animal effigies. Obsidian  was brought in from Puebla, 300 km from  San Lorenzo. And also, Pachuca green obsidian from central Mexico Writing:  The earliest Olmec writing began with glyphs representing calendrical events, and eventually evolved into logographs, line drawings for single ideas. The earliest proto-glyph so far is an Early Formative greenstone carving of a footprint from El Manati. The same sign shows up on a Middle Formative monument 13 at  La Venta  next to a striding figure. The  Cascajal block  shows many early glyph forms. The Olmec designed a printing press of sorts, a roller stamp or cylinder seal, which could be inked and rolled onto human skin, paper, or cloth. Calendar:  260 days, 13 numbers and 20 named days.
