A circle is a simple shape in Euclidean geometry. It is the set of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves so that its distance from a given point is constant. The distance between any of the points and the centre is called the radius.
A circle is a simple closed curve which divides the plane into two regions: an interior and an exterior. In everyday use, the term "circle" may be used interchangeably to refer to either the boundary of the figure, or to the whole figure including its interior; in strict technical usage, the circle is only the boundary and the whole figure is called a disk.
A circle may also be defined as a special ellipse in which the two foci are coincident and the eccentricity is 0, or the two-dimensional shape enclosing the most area per unit perimeter squared, using calculus of variations.
Circle (Turkish: Daire) is a 2014 film written and directed by director Atil Inac.
In the hard-boiled world, where will the soft-shelled end up? A cozy kind of extermination is on the stage and keeping a low profile. The decadence around us is nothing less than clandestine annihilation of the civil man. Yet it is carried out so well with a grinning face, it is officially sold as transition. Now that the tamed indulgent is striped off social justice, welfare, even denied the tender love of concentration camps and slavery plantations of past centuries. At least hand them a round of rope… They have high expectations from taking things in their own hands.
Circle is a peculiar story of an ordinary man caught between an untimely romance and brave new hostile world.
Circle is the name of a stand-up tour by the comedian Eddie Izzard in 2000.
It was released on VHS and DVD in the United Kingdom on 18 November 2002. The video includes Eddie performing a French version of his show with English subtitles.
The performance features many of Izzard's traditional themes, particularly religion (or "philosophies with some good ideas, and some fucking weird ones"). A discussion about Jesus' role in the three main Abrahamic faiths sees him "waiting offstage" in Judaism and playing on the same sporting team as Muhammad in Islam. This is counterpointed with a dialogue between a Crusader and his enemy in which both men are trying to kill the other "in the name of Jesus". He also mentions his impression that in Buddhism, Jesus is "Buddha's baby brother Benny".
The rigidity of religion is also lampooned, particularly as it relates to the Renaissance. Galileo's persecution by the Catholic Church is mentioned, although the man is eventually asked (in prison) "Galileo, Galileo, will you do the fandango?"
A helix is a spiral-like shape.
Helix may also refer to:
Helix was a short-lived, science fiction and science fantasy imprint of DC Comics, launched in 1996 and discontinued in 1998. In early promotional materials prior to the release of the first title, the imprint was called Matrix instead of Helix. It was renamed because of the then-upcoming film, The Matrix. It featured a handful of ongoing monthly series, several limited series, and one short graphic novel.
Despite the involvement of successful science fiction/fantasy novelists Michael Moorcock, Lucius Shepard and Christopher Hinz, and established comics creators Howard Chaykin, Elaine Lee, Matt Howarth, Warren Ellis, Walt Simonson, and Garth Ennis, sales of the comic books were low, and most of the ongoing titles were cancelled after 12 or fewer issues. Ellis' Transmetropolitan was switched to the Vertigo imprint, where it continued for several more years before reaching its planned conclusion. Ennis' Bloody Mary mini-series and Michael Moorcock's Multiverse were later collected in Vertigo-label paperbacks and Moeller's Sheva's War was released as a graphic novel paperback by Dark Horse.
Phelix is a high-speed stream cipher with a built-in single-pass message authentication code (MAC) functionality, submitted in 2004 to the eSTREAM contest by Doug Whiting, Bruce Schneier, Stefan Lucks, and Frédéric Muller. The cipher uses only the operations of addition modulo 232, exclusive or, and rotation by a fixed number of bits. Phelix uses a 256-bit key and a 128-bit nonce, claiming a design strength of 128 bits. Concerns have been raised over the ability to recover the secret key if the cipher is used incorrectly.
Phelix is optimised for 32-bit platforms. The authors state that it can achieve up to eight cycles per byte on modern x86-based processors.
FPGA Hardware performance figures published in the paper "Review of stream cipher candidates from a low resource hardware perspective" are as follows:
Phelix is a slightly modified form of an earlier cipher, Helix, published in 2003 by Niels Ferguson, Doug Whiting, Bruce Schneier, John Kelsey, Stefan Lucks, and Tadayoshi Kohno; Phelix adds 128 bits to the internal state.
