Stack (software)

Stack is a tool to build Haskell projects and manage their dependencies. It uses the Cabal library together with a curated version of the Hackage repository.

Stack competes against Cabal's binary cabal-install and has been created as a result of the overall criticism about dependency problems. It does not, however, provide its own package format, but uses existing *.cabal files and complements projects with an additional stack.yaml file.

Stack (abstract data type)

In computer science, a stack is an abstract data type that serves as a collection of elements, with two principal operations: push, which adds an element to the collection, and pop, which removes the most recently added element that was not yet removed. The order in which elements come off a stack gives rise to its alternative name, LIFO (for last in, first out). Additionally, a peek operation may give access to the top without modifying the stack.

The name "stack" for this type of structure comes from the analogy to a set of physical items stacked on top of each other, which makes it easy to take an item of the top of the stack, while getting to an item deeper in the stack may require taking off multiple other items first.

Considered as a linear data structure, or more abstractly a sequential collection, the push and pop operations occur only at one end of the structure, referred to as the top of the stack. This makes it possible to implement a stack as a singly linked list and a pointer to the top element.

Change!

Change! is the second full-length album by the Black Swans. It is a follow-up to 2004's Who Will Walk in the Darkness with You? and their 2006 EP, Sex Brain. Harp Magazine described the album as a tip of the hat to Charles Simic, the Left Banke, and Fred Neil.

Cover

The cover of the CD release is a painting, "Untitled", by Debbie Porchetti, a member of Arc Industries North Workshop, a branch of Franklin County Board of MRDD. The workshop provides services to 300 adults with developmental challenges and recognize their talents by offering an environment that reinforces their confidence and self-expression. Change! was also released in a limited edition vinyl featuring original, one of a kind artwork by workshop members who applied their expression to 500 blank album sleves.

All songs written and composed by Jerry DeCicca, except "Blue Moon #9" by DeCicca, Faulkner & Forbes.

Mathematics

Mathematics (from Greek μάθημα máthēma, “knowledge, study, learning”) is the study of topics such as quantity (numbers),structure,space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics.

Mathematicians seek out patterns and use them to formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proof. When mathematical structures are good models of real phenomena, then mathematical reasoning can provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity for as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry.

Rigorous arguments first appeared in Greek mathematics, most notably in Euclid's Elements. Since the pioneering work of Giuseppe Peano (1858–1932), David Hilbert (1862–1943), and others on axiomatic systems in the late 19th century, it has become customary to view mathematical research as establishing truth by rigorous deduction from appropriately chosen axioms and definitions. Mathematics developed at a relatively slow pace until the Renaissance, when mathematical innovations interacting with new scientific discoveries led to a rapid increase in the rate of mathematical discovery that has continued to the present day.
