A QR code for the URL of the English Wikipedia Mobile main page A QR code (quick-response code) is a type of two-dimensional matrix barcode, invented in 1994, by Japanese company Denso Wave for labelling automobile parts.[1][2] It features black squares on a white background with fiducial markers, readable by imaging devices like cameras, and processed using Reed–Solomon error correction until the
Genuflection on one knee, during a Catholic Mass Genuflection or genuflexion is the act of bending a knee to the ground, as distinguished from kneeling which more strictly involves both knees. From early times, it has been a gesture of deep respect for a superior. Today, the gesture is common in the Christian religious practices of the Anglicanism,[1] Lutheranism,[2] the Catholic Church,[3] and We

Example of shuffling five letters using Durstenfeld's in-place version of the Fisher–Yates shuffle The Fisher–Yates shuffle is an algorithm for shuffling a finite sequence. The algorithm takes a list of all the elements of the sequence, and continually determines the next element in the shuffled sequence by randomly drawing an element from the list until no elements remain.[1] The algorithm produc
A 1-bit image of the Statue of David, dithered with Floyd–Steinberg algorithm Floyd–Steinberg dithering is an image dithering algorithm first published in 1976 by Robert W. Floyd and Louis Steinberg. It is commonly used by image manipulation software, for example when an image is converted into GIF format, which is restricted to a maximum of 256 colors. The algorithm achieves dithering using error
Kenneth Yigael Goldberg (born 1961) is an American artist, writer, inventor, and researcher in the field of robotics and automation. He is professor and chair of the industrial engineering and operations research department at the University of California, Berkeley, and holds the William S. Floyd Jr. Distinguished Chair in Engineering at Berkeley, with joint appointments in Electrical Engineering
Dollar cost averaging (DCA) is an investment strategy that aims to apply value investing principles to regular investment. The term was first coined by Benjamin Graham in his book The Intelligent Investor. Graham writes that dollar cost averaging "means simply that the practitioner invests in common stocks the same number of dollars each month or each quarter. In this way he buys more shares when
Quantitative easing (QE) is a monetary policy action where a central bank purchases predetermined amounts of government bonds or other financial assets in order to stimulate economic activity.[1] Quantitative easing is a novel form of monetary policy that came into wide application after the financial crisis of 2007–2008.[2][3] It is used to mitigate an economic recession when inflation is very
A NURBS curve. (See also: the animated creation of a NURBS spline.) A NURBS surface Non-uniform rational basis spline (NURBS) is a mathematical model using basis splines (B-splines) that is commonly used in computer graphics for representing curves and surfaces. It offers great flexibility and precision for handling both analytic (defined by common mathematical formulae) and modeled shapes. It is
Inspire is an English-language online magazine published by the organization al-Qaeda in the Arabian Peninsula (AQAP). The magazine is one of the many ways AQAP uses the Internet to reach its audience. Numerous international and domestic extremists motivated by radical interpretations of Islam have been influenced by the magazine and, in some cases, used its bomb-making instructions in their attem
This article may be too technical for most readers to understand. Please help improve it to make it understandable to non-experts, without removing the technical details.

Dieter Rams (born 20 May 1932) is a German industrial designer who is most closely associated with the consumer products company Braun, the furniture company Vitsœ, and the functionalist school of industrial design. His unobtrusive approach and belief in "less, but better" (Weniger, aber besser) design has influenced the practice of design, as well as 20th century aesthetics and culture.[1][2] He
In the mathematical field of numerical analysis, De Casteljau's algorithm is a recursive method to evaluate polynomials in Bernstein form or Bézier curves, named after its inventor Paul de Casteljau. De Casteljau's algorithm can also be used to split a single Bézier curve into two Bézier curves at an arbitrary parameter value. Although the algorithm is slower for most architectures when compared w
