Big O notation

In mathematics, big O notation describes the limiting behavior of a function when the argument tends towards a particular value or infinity, usually in terms of simpler functions. It is a member of a larger family of notations that is called Landau notation, Bachmann–Landau notation (after Edmund Landau and Paul Bachmann), or asymptotic notation. In computer science, big O notation is used to classify algorithms by how they respond (e.g., in their processing time or working space requirements) to changes in input size. In analytic number theory, it is used to estimate the "error committed" while replacing the asymptotic size, or asymptotic mean size, of an arithmetical function, by the value, or mean value, it takes at a large finite argument. A famous example is the problem of estimating the remainder term in the prime number theorem.

Big O notation characterizes functions according to their growth rates: different functions with the same growth rate may be represented using the same O notation.

Harry Potter

Harry Potter is a series of seven fantasy novels and one play written by British author J. K. Rowling. The series chronicles the life of a young wizard, Harry Potter, and his friends Hermione Granger and Ron Weasley, all of whom are students at Hogwarts School of Witchcraft and Wizardry. The main story arc concerns Harry's struggle against the Dark wizard Lord Voldemort, who aims to become immortal, overthrow the Ministry of Magic, subjugate non-magic people and destroy anyone who stands in his way.

Since the release of the first novel, Harry Potter and the Philosopher's Stone, on 30 June 1997, the books have gained immense popularity, critical acclaim and commercial success worldwide. They attracted a wide adult audience, and have remained one of the preeminent cornerstones of young adult literature. The series has also had some share of criticism, including concern about the increasingly dark tone as the series progressed, as well as the often gruesome and graphic violence depicted in the series. As of July 2013, the books have sold more than 450 million copies worldwide, making the series the best-selling book series in history, and have been translated into 73 languages. The last four books consecutively set records as the fastest-selling books in history, with the final instalment selling roughly 11 million copies in the United States within the first 24 hours of its release.

Black Label Society

Black Label Society is an American heavy metal band from Los Angeles, California formed in 1998 by Zakk Wylde. The band has, thus far, released nine studio albums, two live albums, two compilation albums, one EP, and three video albums.

History

Sonic Brew and Formation (1998–1999)

In the early 1990s, Wylde had formed his own solo band Pride & Glory, playing a mixture of bluesy southern rock with heavy metal. However, they disbanded in December 1994 after having released only one album. Wylde subsequently recorded an acoustic solo album, Book of Shadows (released 1996). In May 1998, after limited commercial success with Book of Shadows, Wylde and drummer Phil Ondich recorded what became Black Label Society's debut album Sonic Brew. It was decided, rather than the album being another solo album for Wylde, that they would form a long term band. It was known from the start that Nick Catanese would be retained as the second guitarist in the band (Catanese previously toured as rhythm guitarist for the Book Of Shadows tour). John DeServio, who previously worked with Wylde as a temporary replacement in Pride & Glory, joined as the band's bassist for the album's tour.
