Analog is a free web log analysis software program that runs under Windows, Mac OS, Linux, and most Unix-like operating systems. It was first released on June 21, 1995, by Stephen Turner as generic freeware; the license was changed to the GNU General Public License in November 2004. The software can be downloaded for several computing platforms, or the source code can be downloaded and compiled if desired.[1]
Analog has support for 35 languages,[2] and provides the ability to do reverse DNS lookups on log files, to indicate where web site hits originate. It can analyze several different types of web server logs, including Apache, IIS, and iPlanet.[3] It has over 200 configuration options and can generate 32 reports.[2] It also supports log files for multiple virtual hosts.[2]
The program is comparable to Webalizer or AWStats, though it does not use as many images, preferring to stick with simple bar charts and lists to communicate similar information. Analog can export reports in a number of formats including HTML, XHTML, XML, Latex and a delimited output mode (for example CSV) for importing into other programs. Delimited or "computer" output from Analog is often used to generate more structured and graphically rich reports using the third party Report Magic program.
The popularity of Analog is largely unknown as no download count information has been released on its historic dissemination. In a 1998 survey by the Graphic, Visualization, & Usability Center (GVU), Analog was reportedly used by 24.9%[4] (up from 19.9% the year before[5]), with its nearest rival, Web Trends holding some 20.3% of the market.
It is not clear how Analog's usage has changed into the decade leading up to 2010, neither on how its usage profile has been impacted by on-line analysis services such as Google Analytics. Analog does remain relevant however given that it can operate on an individual or web-farm basis from a single process, requiring no modification of web page or web script code in order to use it. As it is a stand-alone utility, its use does not raise issues of privacy or data protection as are often concerns highlighted over the use of on-line services. Additionally, unlike with on-line script included services, it is not possible for visiting clients to block all of the logging of traffic directly from the client - improving the reliability of the log data.
Analog has not been officially updated since the version 6.0 release in December 2004. The original author moved on to commercial traffic analysis. Updates to Analog continued informally by its user community up until the end of 2009 on the official mailing list. Currently the only formally compiled updated redistributable of Analog is that of Analog C:Amie Edition, which has focused on fixing issues in Analog's XML DTD and on adding new operating system and web browser detection to the original code branch.

Analog signal
An analog or analogue signal is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e., analogous to another time varying signal. For example, in an analog audio signal, the instantaneous voltage of the signal varies continuously with the pressure of the sound waves. It differs from a digital signal, in which the continuous quantity is a representation of a sequence of discrete values which can only take on one of a finite number of values. The term analog signal usually refers to electrical signals; however, mechanical, pneumatic, hydraulic, human speech, and other systems may also convey or be considered analog signals.
An analog signal uses some property of the medium to convey the signal's information. For example, an aneroid barometer uses rotary position as the signal to convey pressure information. In an electrical signal, the voltage, current, or frequency of the signal may be varied to represent the information.
Structural analog
Structural analogs (structural analogue or simply analog) are models or representations that keep each other certain "structural similarity". It is used in engineering, chemistry, mathematics and other fields.
Despite the field diversity, all structural analog analysis use some level of abstraction to transform models in mathematical graphs, and detected structural analogies by algorithms. Example: for molecular structure comparison and classification operations, the compared compounds are modeled as a mathematical graph. Formally, when structures are represented by graphs, the concept of analog is related to a graph isomorphism.
Systems engineering
Analogical models are used in a method of representing a ‘target system’ by another, more understandable or analysable system.
Two systems have analog structures (see illustration) if they are isomorphic graphs and have equivalent (mapped) lumped elements. In Electronics, methods based on fault models of structural analogs gain some acceptance in industry.
Dagon
Dagon (Hebrew: דגון', Tib. Dāḡôn) or Dagan (Ugaritic: Dgn, Dagnu, or Daganu; Akkadian: Dagana) was originally an East Semitic Mesopotamian (Akkadian, Assyrian, Babylonian) fertility god who evolved into a major Northwest Semitic god, reportedly of grain (as symbol of fertility) and fish and/or fishing (as symbol of multiplying). He was worshipped by the early Amorites and by the inhabitants of the cities of Ebla (modern Tell Mardikh, Syria) and Ugarit (modern Ras Shamra, Syria). He was also a major member, or perhaps head, of the pantheon of the Philistines.
Name
In Ugaritic, the root dgn also means grain: in Hebrew דגן dāgān, Samaritan dīgan, is an archaic word for grain.
The Phoenician author Sanchuniathon also says Dagon means siton, that being the Greek word for grain. Sanchuniathon further explains: "And Dagon, after he discovered grain and the plough, was called Zeus Arotrios." The word arotrios means "ploughman", "pertaining to agriculture" (confer ἄροτρον "plow").
It is perhaps related to the Middle Hebrew and Jewish Aramaic word dgnʾ 'be cut open' or to Arabic dagn (دجن) 'rain-(cloud)'.
Fomalhaut b
Fomalhaut b or Dagon is a confirmed, directly imaged extrasolar object and candidate planet orbiting the A-type main-sequence star Fomalhaut, approximately 25 light-years away in the constellation of Piscis Austrinus. The object was initially announced in 2008 and confirmed as real in 2012 from images taken with the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope and, according to calculations reported in January 2013, has a 1,700-year, highly elliptical orbit. It has a periastron of 7.4 billion km (~50 AU) and an apastron of about 44 billion km (~300 AU). As of May 25, 2013 it is 110 AU from its parent star.
The planet was one of those selected by the International Astronomical Union as part of their public process for giving proper names to exoplanets. The process involved public nomination and voting for the new name. In December 2015, the IAU announced the winning name was Dagon. The name Dagon was proposed by Dr. Todd Vaccaro and forwarded by the St. Cloud State University Planetarium to the IAU for consideration.
Nightrider (DC Comics)
Nightrider (Dagon) is a fictional vampire superhero from the DC Comics universe. He is a member of the Team Titans, a rebel group seeking to overthrow Lord Chaos, the dictator of an alternate Earth ten years into the future.
Fictional character biography
David was an ordinary mortal boy growing up in London. When he was ten, he was hit by a truck. Lord Chaos took a special interest in him, making him a test subject.
At fourteen, he was the subject of an experiment in which he was infused with DNA drawn from the bones of Dracula. This turned him into a blood-hungering monster he dubbed "Dagon", because he felt as if David, the person he used to be, was dead. During the experiment, a demon attacked the research team; Dagon joined it and singled out the chief researcher for special attention. The only survivor was Charlie Watkins, who would later become the hero Killowat.
Dagon joined the Team Titans to get revenge on Lord Chaos, adopting the name Nightrider. They taught him how to control his hunger and assigned him to a team.
