ARC (file format)

ARC is a lossless data compression and archival format by System Enhancement Associates (SEA). It was very popular during the early days of networked dial-up BBS. The file format and the program were both called ARC. The ARC program made obsolete the previous use of a combination of the SQ program to compress files and the LU program to create .LBR archives, by combining both compression and archiving functions into a single program. Unlike ZIP, ARC is incapable of compressing entire directory trees. The format was subject to controversy in the 1980s—an important event in debates over what would later be known as open formats.

The .arc file extension is often used for several file archive-like file types. For example, the Internet Archive uses its own ARC format to store multiple web resources into a single file. The FreeArc archiver also uses .arc extension, but uses a completely different file format.

Nintendo uses an unrelated 'ARC' format for resources, such as MIDI, voice samples, or text, in GameCube and Wii games. Several unofficial extractors exist for this type of ARC file.

Critical reception

Freddie Holmes of The Underclassed gave the album a positive review stating:

7digital featured Arc as album of the week, praising the record as "schizophrenic, electro-pop perfection."

Arc (projective geometry)

A (simple) arc in finite projective geometry is a set of points which satisfies, in an intuitive way, a feature of curved figures in continuous geometries. Loosely speaking, they are sets of points that are far from "line-like" in a plane or far from "plane-like" in a three-dimensional space. In this finite setting it is typical to include the number of points in the set in the name, so these simple arcs are called k-arcs. An important generalization of the k-arc concept, also referred to as arcs in the literature, are the (k, d)-arcs.

k-arcs in a projective plane

In a finite projective plane π (not necessarily Desarguesian) a set A of k (k ≥ 3) points such that no three points of A are collinear (on a line) is called a k - arc. If the plane π has order q then k ≤ q + 2, however the maximum value of k can only be achieved if q is even. In a plane of order q, a (q + 1)-arc is called an oval and, if q is even, a (q + 2)-arc is called a hyperoval.

Every conic in the Desarguesian projective plane PG(2,q), i.e., the set of zeros of an irreducible homogeneous quadratic equation, is an oval. A celebrated result of Beniamino Segre states that when q is odd, every (q + 1)-arc in PG(2,q) is a conic. This is one of the pioneering results in finite geometry.

Sunan (Indonesian title)

Sunan is the shorter version of "Susuhunan", both used as an honorific in Java Indonesia.

According to Hamka in his book Dari Perbendaharaan Lama the word derived from a Javanese word for position (susunan) of hands in reverential salutation, done with hands pressed together, palms touching and fingers pointed upwards, and bowing. This arrangement which has some similarities with Indian "namaste" is called "sembah", which is used to honor and praise. From this "Susuhunan" can mean someone to give the "susunan"/"sembah" to a revered person. Another word for "Susuhunan" is "Sesembahan".

This title is given by the Javanese and Sundanese to rulers, clerics and even deities. A common usage is for the 'Sunans', or the Nine Saints (Wali Songo), who were the spreaders of Islam in Java. Also, Sunan Ambu (Queen Mother/Goddess Mother) is a female deity revered by the Sundanese.
