The computer

A computer is a machine for manipulate data according to a list of commands known as a program. Computers are tremendously adaptable. In fact, they are universal information-processing machines. According to the Church–Turing theory, a computer with a positive minimum entrance capability is in principle capable of performing the responsibilities of any other computer. Therefore, computers with capability ranging from those of a personal digital supporter to a supercomputer may all achieve the same tasks, as long as time and memory capacity are not consideration. Therefore, the same computer design may be modified for tasks ranging from doling out company payrolls to controlling unmanned spaceflights. Due to technical progression, modern electronic computers are exponentially more capable than those of preceding generations. Computers take plentiful physical forms. Early electronic computers were the size of a large room, while whole modern embedded computers may be lesser than a deck of playing cards. Even today, huge computing conveniences still exist for focused scientific computation and for the transaction processing necessities of large organizations. Smaller computers designed for personage use are called personal computers. Along with its convenient equivalent, the laptop computer, the personal computer is the ubiquitous in order processing and communication tool, and is typically what is meant by "a computer". However, the most general form of computer in use today is the embedded computer. Embedded computers are usually comparatively simple and physically small computers used to control one more device. They may control equipment from fighter aircraft to industrial robots to digital cameras. in the beginning, the term "computer" referred to a person who performed numerical calculations, frequently with the aid of a mechanical calculating device or analog computer. In 1801, Joseph Marie Jacquard made an improvement to the presented loom designs that used a series of punched paper cards as a program to weave involved patterns. The resulting Jacquard loom is not considered a true computer but it was an essential step in the growth of modern digital computers.
Charles Babbage was the first to conceptualize and design a completely programmable computer as early as 1820, In 1801, Joseph Marie Jacquard made an improvement to the presented loom designs that used a series of punched paper cards as a program to weave involved patterns. The resulting Jacquard loom is not considered a true computer but it was an essential step in the growth of modern digital computers.
but due to a combination of the restrictions of the technology of the time, limited finance, and an incapability to resist tinkering with his design, the device was never really constructed in his lifetime. By the end of the 19th century a number of technologies that would later prove helpful in computing had appeared, out such as the punch card and the vacuum tube, and large-scale automated data giving using punch cards was performed by tabulating equipment designed by Hermann Hollerith.During the first half of the 20th century, many technical computing wants were met by increasingly difficult special-purpose analog computers, which used a direct mechanical or electrical model of the problem as a base for subtraction . Sequence of gradually more powerful and stretchy computing devices were construct in the 1930s and 1940s.

Chaka Khan

Chaka Khan is the stage name of American singer Yvette Marie Stevens.Khan first came to the attention of the music world as the singer of the funk band Rufus in the mid-1970s and with the help of Stevie Wonder, broke into both the pop and R&B charts in 1974 with the hit "Tell Me Something Good". Throughout the 1970's and early 1980's, the band had a number of R&B hits including "Ain't Nobody", "Masterjam", "Sweet Thing", "Do You Love What You Feel?", and "Everlasting Love". In 1978, launched her smash hit: "I'm Every Woman". A few years later, Khan released her hip-hop based hit, "I Feel for You", written by Prince, which launched her recording career back into full gear.
Khan's career has been gratifying in terms of record sales, but she continues to record and expand musically. Her legacy as a soul icon is indisputable.In September 2004 her 25 year old son Damien Patrick Holland was arrested on charges of murder in the first degree.On December 3, 2004, she received an honorary doctorate degree from Berklee College of Music.

Vienna is the capital of Austria, and also one of the nine States of Austria. Vienna is Austria's primate city; with a population of about 1.6 million, Vienna is by far the largest city in Austria as well as its cultural, economic and political centre. Vienna lies in the south-eastern corner of Central Europe and is close to the Czech Republic, Slovakia and Hungary.

Vienna is the seat of a number of United Nations offices and various international institutions and companies, including the United Nations Industrial Development Organization, the Organization of Petroleum Exporting Countries, the International Atomic Energy Agency, the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization and the Organization for Security and Co-operation in Europe. Furthermore, the 1980 Diplomatic Conference was held in Vienna that led to the adoption of the United Nations Convention of Contracts for the International Sale of Goods. Additionally, Vienna is the seat of the United Nations Commission on International Trade Law's secretariat.

The Stalinist version of socialism, with some important modifications, shaped the Soviet Union and influenced Communist Parties worldwide. It was heralded as a possibility of building communism via a massive program of industrialization and collectivization. The rapid development of industry, and above all the victory of the Soviet Union in the Second World War, maintained that vision throughout the world, even around a decade following Stalin's death, when the party adopted a program in which it promised the establishment of communism within thirty years.
However, under Stalin's leadership, evidence emerged that dented faith in the possibility of achieving communism within the framework of the Soviet model. Stalin had created in the Soviet Union a repressive state that dominated every aspect of life. Later, growth declined, and rent-seeking and corruption by state officials increased, which dented the legitimacy of the Soviet system.
Despite the activity of the Comintern, the Soviet Communist Party adopted the Stalinist theory of "socialism in one country" and claimed that, due to the "aggravation of class struggle under socialism," it was possible, even necessary, to build socialism in one country alone.This departure from Marxist internationalism was challenged by Leon Trotsky, whose theory of "permanent revolution" stressed the necessity of world revolution.

White tigers

White tigers are Bengal tigers or tigers of mixed Bengal/Amur ancestry with pink noses, white-to-creme coloured fur and black, grey or chocolate-coloured stripes. Their eyes are usually blue, but may be green or amber. There are several hundred captive white tigers worldwide, all of whom can trace their ancestry back to a white Bengal tiger caught in Rewa, India.
Due to the opinion that their colouration is widely considered striking, white tigers have become popular attractions in zoos and entertainment that showcases exotic animals; the magicians Siegfried and Roy are famous for using several trained white tigers in their shows. Contrary to popular belief, white tigers are not a separate species in their own right, but are a mutant form of the orange Bengal tigers.
