A principal thrust of innovation today continues toward technological advances that enhance the productivity of labor and free humans of tasks done more economically by machines. An insatiable appetite for convenience, comfort, The evolution of the computer entertainment products and services, as well as for means to overcome natural barriers like geography and travel time, creates a constant pull on technology.

The pull is especially strong in areas relating to the quality of life, and there have been many technical innovations to meet that need. But the opportunities are far from exhausted.

Among society's newest demands on technology is for the means to handle the vast amount of information generated by modern life. This information explosion stems from sophisticated business practices, new residential services, substantially increased record keeping through extensive data bases, and the globalization of our advanced society.

The evolution of the computer

The information technologies have evolved over many years to assist a growing portion of the work force devoted to the generation, 7 8 JOHN S. AlAYO processing, transmission, storage, retrieval, and general use of infor- mation. Bureaucracies generated dunug the major wars and the rapid growth of social services in recent decades have helped increase the number of infonnation workers in the U.

Stimulated by these and other spurts of rapid growth, the percentage of information workers in the U. Since the fraction has held at roughly 50 percent, probably as a result of the new electronic infonnation technologies that augment human efforts. The computer, along with telecommunications, is making today's infor- mation work force more efficient, much as the engine raised produc- tivity during the industrial revolution.

In both cases, society's thirst for technology to reduce labor was met in striking ways by a wide range of innovations of varying impacts. This thirst for technology creates a steady pull on innovation. In addition, the technologies themselves provide a push.

From the families of all technologically feasible innovations of all time has come an almost endless reservoir of potential technology. However, between society's pull and the push of technology are two powerful gates, as shown in Figure 1. On the one hand, this force can limit the introduction of new technology as well as discourage breakthroughs in totally new directions.

Guiding Tech

On the other hand, it brings focus and resources. With good systems engineering, older technologies can be phased out, current ones upgraded, and entirely new ones introduced, all in ways that are synergistic with the embedded base.

Natural sequencing simply means that the invention of the integrated circuit, for example, would have been unlikely before the invention and development of the transistor. Innovations that pass the technology gate must also pass the social gate. The forces that operate the social gate include economics, the common good, public receptivity, and regulation and legislation: The economic force depends not only on the marketplace, but also on the national economic structure.

Currently, we see a significant difference in the way economic forces affect innovation in the United States as compared to Japan. Society will even- tually, for the most part, either ignore or legislate against technology that does not serve the common good. The issue of public receptivity is related to that of the common good.

In the United States, the public defeated the supersonic transport and appears to have nuclear power on its deathbed; however, it still remains to be seen whether such innovations do not indeed serve the common good. AtA YO Much social good has come from such actions, but not without frequent adverse impact in the long run.

The forces operating at the social gate are extremely powerful in selecting the innovations that actually succeed. They serve as a "tollgate" in the gap between the push of technology and the pull of society.Here are phylogeny packages and 54 free web servers, (almost) all that I know is an attempt to be completely comprehensive.

I have not made any attempt to exclude programs that do not meet some standard of quality or importance. The Evolution of Human Computer Interface and Beyond The Evolution of Human Computer Interface and Beyond Contents 1.

The design of the iPad was unprecedented, however, with a inch screen made with scratch-resistant glass. The portable computer features internet connectivity, photo and video camera access, apps, music, iBooks, and other multimedia functions.

The largest of the series, the inch iPad Pro, was released on November 11, Condensing + years of the history of computer science into one infographic. See how we went from Leibniz to the iPhone in such a short period of time.

Harvard Mark 1 is completed. Computers; Conceived by Harvard physics professor Howard Aiken, and designed and built by IBM, the Harvard Mark 1 . In computer science, evolutionary computation is a family of algorithms for global optimization inspired by biological evolution, and the subfield of artificial intelligence and soft computing studying these algorithms.
