The Aztecs first lived on islands in Western Mexico and began to migrate in the 11th century. According to legend, they were inspired by God that if an eagle stood on a cactus and pecked a snake, it would be the place to settle down. In 1325, they established Tenochtitlán, now Mexico City, on two islands of Texcoco Lake, under the leadership of their leader.


North America

Paleo-Indians in the western Great Plains and Eastern North America had similar economic activities despite their different environments. In the western part of the United States, from Oregon to northern Mexico, from the Pacific coast to the eastern Rocky Mountains, Indians with desert culture live by hunting and gathering fruits, but primitive agricultural technology has developed.

Central America

More than 10,000 years ago, the Indians entered Central America between Nicaragua and Northern Mexico. The development of farming technology can be traced back to about 4500 B.C. The steady progress of agricultural technology led to the establishment of an agricultural society around 2000 years ago. As the food supply became more stable, small settlements evolved into large towns and stimulated the growth of pottery and other arts.

South America

According to archaeological records, South American civilization began in 10,000 B.C., when the first North American and Central American immigrants arrived. They settled in Tierra del Fuego, Argentina, southern Chile, the central and southern plains of the Grand Canyon and parts of the Central Andes Mountains. Their group is based on kinship, and classes are determined by gender and age. These nomadic groups were later replaced by highly agricultural societies. Agricultural societies are located in the coastal and inland forest areas of Arawak, Brazil and Greater Antilles.


About Programming, Constructor(I)

Programming is very important for related technology companies because the most of online applications and online website need to be shown after technology of programmers’ typing code and development of coding around the world. Meanwhile, related so many programs like JAVA, PHP and so on, there is the constructor to be known and grasped by all of the programmers no matter senior programmers or newbies. Today, according to the topic of constructor, we will discuss a while.steel coil manufacturers

Simply understand about Constructor Function

Constructor (also is called constructor function) is a special method. It is mainly used to initialize the object when creating the object, that is, to assign the initial value to member variable of the object, and it is always used in the statement of creating the object together with the new operator.

A particular class can have multiple constructors, which can be distinguished by the number of parameters or the type of parameters, i.e. the overload of constructors.

Constructor is a special member function. Its name is as same as class name, without return value. Constructor does not need to be called by users, but automatically executes when creating the objects.

The use of constructor function is about to instantiate. For example, a model of a high-rise drawn on a drawing into a real building. In this case ‘this’ means point. It is used to distinguish the parameter of point from other parameters (that is, parameters in brackets).

Some Actions From Technology Tycoon Google(II)

About new campus

Google’s investment in high-quality real estate in Mountain View, California, to the west of lower Manhattan also highlights the growing importance of New York as an innovation center and incubator for technology companies.

Ruth Porat, chief financial officer of Alphabet and Google, said “We are growing faster outside the Bay Area than within it.” Atlantic Equities analyst James Cordwell said “It is a ‘fairly sensible’ move for Google given the amount of available talent pool.” Cordwell added again “It also makes sense for Google as New York has been the center for their core advertising business.” With too many white-collar workers and good infrastructure, square steel tubing for sale the city offers a better choice for other places that need more investment.

Last month, the Wall Street Journal reported that Google was about to reach an agreement to buy or lease an office building in New York City to increase office space for more than 12,000 new employees. Google announced a $2.4 billion purchase of Chelsea in Manhattan earlier this year. Google has also leased a space at Pier57 to connect with Hudson Street, which will create a four-block office park or saying campus.
