Aesthetics

Aesthetics, or the philosophy of art, is the study of beauty and taste. It is about interpreting works of art and art movements or theories. The term aesthetic is also used to designate a particular style, for example the "chess aesthetics", or the "Japanese aesthetic".

As well as being applied to art, aesthetics can also be applied to cultural objects. Aesthetic design principles include ornamentation, edge delineation, texture, flow, solemnity, symmetry, color, granularity, the interaction of sunlight and shadows, transcendence, and harmony.

The word aesthetic is also an adjective and adverb relating to cosmetology and medicine, as in aesthetic medicine.

Also spelt æsthetics and esthetics, the word is derived from the Ancient Greek αἰσθητικός (aisthetikos, meaning "esthetic, sensitive, sentient, pertaining to sense perception"), which in turn was derived from αἰσθάνομαι (aisthanomai, meaning "I perceive, feel, sense").

History of aesthetics in western philosophy

The idea of the aesthetic developed from the idea of taste and beauty. Before the early 1700s, thinkers developed general theories of proportion and harmony, detailed most specifically in architecture and music. An extended, philosophical reflection on aesthetics emerged with the widening of leisure activities in the eighteenth century.

Aesthetics of music

In the pre-modern tradition, the aesthetics of music or musical aesthetics explored the mathematical and cosmological dimensions of rhythmic and harmonic organization. In the eighteenth century, focus shifted to the experience of hearing music, and thus to questions about its beauty and human enjoyment (plaisir and jouissance) of music. The origin of this philosophic shift is sometimes attributed to Baumgarten in the 18th century, followed by Kant. Through their writing, the ancient term aesthetics, meaning sensory perception, received its present-day connotation. In recent decades philosophers have tended to emphasize issues besides beauty and enjoyment. For example, music's capacity to express emotion has been a central issue.

Aesthetics is a sub-discipline of philosophy. In the 20th century, important contributions were made by Peter Kivy, Jerrold Levinson, Roger Scruton, and Stephen Davies. However, many musicians, music critics, and other non-philosophers have contributed to the aesthetics of music. In the 19th century, a significant debate arose between Eduard Hanslick, a music critic and musicologist, and composer Richard Wagner regarding whether instrumental music could communicate emotions to the listener. Harry Partch and some other musicologists, such as Kyle Gann, have studied and tried to popularize microtonal music and the usage of alternate musical scales. Also many modern composers like La Monte Young, Rhys Chatham and Glenn Branca paid much attention to a system of tuning called just intonation.

Off!

Off! is an American hardcore punk supergroup, formed in Los Angeles in 2009.

History

Off! was formed in Los Angeles, California in late 2009 by Circle Jerks/Black Flag singer Keith Morris, Burning Brides frontman Dimitri Coats, Redd Kross bassist Steven Shane McDonald, and Rocket From The Crypt/Hot Snakes drummer Mario Rubalcaba. The idea to form the band came after Coats had worked as producer on a Circle Jerks album which fell apart. During that time, Coats and Morris had written several songs together which they used to start Off!. The group made its live debut at the 2010 South By Southwest Music Festival in Austin, Texas. Off!'s first Los Angeles show featured an original art installation by Raymond Pettibon at a downtown warehouse space.

The first release by Off! is a 7" vinyl EP called 1st EP, which debuted on October 13, 2010. That EP, along with three more EPs, were later released as a four 7" vinyl box set entitled First Four EPs on December 14, 2010. The collection contains sixteen songs and features artwork by Raymond Pettibon.

Environment variable

Environment variables are a set of dynamic named values that can affect the way running processes will behave on a computer.

They are part of the environment in which a process runs. For example, a running process can query the value of the TEMP environment variable to discover a suitable location to store temporary files, or the HOME or USERPROFILE variable to find the directory structure owned by the user running the process.

They were introduced in their modern form in 1979 with Version 7 Unix, so are included in all Unix operating system flavors and variants from that point onward including Linux and OS X. From PC DOS 2.0 in 1982, all succeeding Microsoft operating systems including Microsoft Windows, and OS/2 also have included them as a feature, although with somewhat different syntax, usage and standard variable names.

Details

In all Unix and Unix-like systems, each process has its own separate set of environment variables. By default, when a process is created, it inherits a duplicate environment of its parent process, except for explicit changes made by the parent when it creates the child. At the API level, these changes must be done between running fork and exec. Alternatively, from command shells such as bash, a user can change environment variables for a particular command invocation by indirectly invoking it via env or using the ENVIRONMENT_VARIABLE=VALUE <command> notation. All Unix operating system flavors, DOS, and Windows have environment variables; however, they do not all use the same variable names. A running program can access the values of environment variables for configuration purposes.
