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.

Analyst

An analyst is an individual who performs analysis of a topic. The term may refer to one of the following professions:

Analyst (journal)

Analyst is a biweekly peer-reviewed scientific journal covering all aspects of analytical chemistry, bioanalysis, and detection science. It is published by the Royal Society of Chemistry. The executive editor is May Copsey.

Analyst was established in 1876 by the Society for Analytical Chemistry as The Analyst and obtained its current name in 2009. According to the Journal Citation Reports, it has a 2014 impact factor of 4.107. It is abstracted and indexed in MEDLINE and Analytical Abstracts.

In 1999, the society closed the journal Analytical Communications because it felt that the material submitted to that journal would be best in a new communications section of Analyst. Predecessor journals of Analytical Communications were:

List of mass spectrometry software

Mass spectrometry software is software used for data acquisition, analysis, or representation in mass spectrometry.

Proteomics software

In protein mass spectrometry, tandem mass spectrometry (also known as MS/MS or MS²) experiments are used for protein/peptide identification. Peptide identification algorithms fall into two broad classes: database search and de novo search. The former search takes place against a database containing all amino acid sequences assumed to be present in the analyzed sample, whereas the latter infers peptide sequences without knowledge of genomic data.

Database search algorithms

De novo sequencing algorithms

De novo peptide sequencing algorithms are based, in general, on the approach proposed in Bartels et al. (1990).
