Common Gateway Interface

Common Gateway Interface (CGI) is a standard way for web servers to interface with executable programs installed on a server that generate web pages dynamically. Such programs are known as CGI scripts or simply CGIs; they are usually written in a scripting language, but can be written in any programming language.

History

In 1993 the National Center for Supercomputing Applications (NCSA) team wrote the specification for calling command line executables on the www-talk mailing list; however, NCSA no longer hosts the specification. The other Web server developers adopted it, and it has been a standard for Web servers ever since. A work group chaired by Ken Coar started in November 1997 to get the NCSA definition of CGI more formally defined. This work resulted in RFC 3875, which specified CGI Version 1.1. Specifically mentioned in the RFC are the following contributors:

CGI Group

CGI Group Inc.,Conseillers en gestion et informatique more commonly known as CGI, is a global information technology (IT) consulting, systems integration, outsourcing, and solutions company headquartered in Montreal, Canada. Founded in 1976 by Serge Godin and André Imbeau as an IT consulting firm, the company soon began branching into new markets and acquiring other companies. CGI went public in 1986 with a primary listing on the Toronto Stock Exchange. CGI is also a constituent of the S&P/TSX 60, and has a secondary listing on the New York Stock Exchange. After almost doubling in size with the 1998 acquisition of Bell Sygma, CGI acquired IMRGlobal in 2001 for $438 million, which added "global delivery options" for CGI. Other significant purchases include American Management Systems (AMS) for $858 million in 2004, which grew CGI's presence in the United States, Europe and Australia and led to the formation of the CGI Federal division.

CGI Federal's 2010 acquisition of Stanley, Inc. for $1.07 billion almost doubled CGI's presence in the United States, and expanded CGI into defense and intelligence contracts. In 2012 CGI acquired Logica for $2.7 billion Canadian, making CGI the fifth-largest independent business processes and IT services provider in the world, and the biggest tech firm in Canada. In 2014 CGI ranked No. 974 on the Forbes Forbes Global 2000, which ranks the world's largest public companies. At the time CGI had assets worth USD $11.1 billion, annual sales of $9.9 billion, and a market value of $9.6 billion. As of 2015 CGI is based in forty countries with around 400 offices, and employs approximately 65,000 people. Canada made up 15% of CGI's client base of March 2015. 29% was in the United States, while around 40% of their commissions came from Europe. 15% was the rest of the world.

Innovation

Innovation is a new idea, or more-effective device or process. Innovation can be viewed as the application of better solutions that meet new requirements, unarticulated needs, or existing market needs. This is accomplished through more-effective products, processes, services, technologies, or business models that are readily available to markets, governments and society. The term "innovation" can be defined as something original and more effective and, as a consequence, new, that "breaks into" the market or society.

While a novel device is often described as an innovation, in economics, management science, and other fields of practice and analysis, innovation is generally considered to be the result of a process that brings together various novel ideas in a way that they have an impact on society.

Inter-disciplinary views

Business and economics

In business and economics, innovation can be a catalyst to growth. With rapid advancements in transportation and communications over the past few decades, the old world concepts of factor endowments and comparative advantage which focused on an area’s unique inputs are outmoded for today’s global economy. Economist Joseph Schumpeter, who contributed greatly to the study of innovation economics, argued that industries must incessantly revolutionize the economic structure from within, that is innovate with better or more effective processes and products, as well as market distribution, such as the connection from the craft shop to factory. He famously asserted that “creative destruction is the essential fact about capitalism”. In addition, entrepreneurs continuously look for better ways to satisfy their consumer base with improved quality, durability, service, and price which come to fruition in innovation with advanced technologies and organizational strategies.

Innovation (signal processing)

In time series analysis (or forecasting) — as conducted in statistics, signal processing, and many other fields — the innovation is the difference between the observed value of a variable at time t and the optimal forecast of that value based on information available prior to time t. If the forecasting method is working correctly successive innovations are uncorrelated with each other, i.e., constitute a white noise time series. Thus it can be said that the innovation time series is obtained from the measurement time series by a process of 'whitening', or removing the predictable component. The use of the term innovation in the sense described here is due to Hendrik Bode and Claude Shannon (1950) in their discussion of the Wiener filter problem, although the notion was already implicit in the work of Kolmogorov.

Innovation (magazine)

Innovation is a subscription-based magazine, compiling recent developments in the area of research in Singapore and globally. The format and style is designed to be accessible to an "educated layperson", and also includes relevant fields such as patenting. The magazine is jointly published by the National University of Singapore and World Scientific.

To date, local Singaporean companies such as the Defence, Science and Technology Agency (DSTA) and academia have been featured in the magazine.
