Krampus, the "Christmas Devil" of Austrian and Bavarian folklore, has entered the popular culture of North America; who noted,  that "thanks to the Internet and YouTube [Krampus] is now very much on America's Christmas radar", an Internet meme, is an activity, concept, catchphrase or piece of media which spreads, often as mimicry or for humorous purposes, from person to person, via the Internet?
Krampus in popular culture Krampus, the "Christmas Devil" of Austrian and Bavarian folklore, has entered the popular culture of North America; Christian Jacobs notes that "thanks to the Internet and YouTube [Krampus] is now very much on America's Christmas radar". Tanya Basu interprets this as part of a "growing movement of anti-Christmas celebrations": a "bah, humbug" rejection of – or novel alternative to – mainstream festivities. Brian Joines of Image Comics suspects that the reason Krampus (specifically, as well as dark aspects of Christmas in general) has not been historically popularized in America is a social artifact resulting from "the nature of how we view Christmas in this country, both as a big day for kids and as the birth of a big religious figurehead". In some North American depictions, Krampus is an antihero who seeks to prevent children from becoming spoiled by rampant consumerism flowing from the economics of Christmas.
Content sniffing Content sniffing, also known as media type sniffing or MIME sniffing, is the practice of inspecting the content of a byte stream to attempt to deduce the file format of the data within it. Content sniffing is generally used to compensate for a lack of accurate metadata that would otherwise be required to enable the file to be interpreted correctly. Content sniffing techniques tend to use a mixture of techniques that rely on the redundancy found in most file formats: looking for file signatures and magic numbers, and heuristics including searching for well-known representative substrings, the use of byte frequency and "n"-gram tables, and Bayesian inference.
