Data segment

In computing, a data segment (often denoted .data) is a portion of an object file or the corresponding virtual address space of a program that contains initialized static variables, that is, global variables and static local variables. The size of this segment is determined by the size of the values in the program's source code, and does not change at run time.

The data segment is read-write, since the values of variables can be altered at run time. This is in contrast to the read-only data segment (rodata segment or .rodata), which contains static constants rather than variables; it also contrasts to the code segment, also known as the text segment, which is read-only on many architectures. Uninitialized data, both variables and constants, is instead in the BSS segment.

Historically, to be able to support memory address spaces larger than the native size of the internal address register would allow, early CPUs implemented a system of segmentation whereby they would store a small set of indexes to use as offsets to certain areas. The Intel 8086 family of CPUs provided four segments: the code segment, the data segment, the stack segment and the extra segment. Each segment was placed at a specific location in memory by the software being executed and all instructions that operated on the data within those segments were performed relative to the start of that segment. This allowed a 16-bit address register, which would normally provide 64KiB (65536 bytes) of memory space, to access a 1MiB (1048576 bytes) address space.

DATA (band)

DATA were an electronic music band created in the late 1970s by Georg Kajanus, creator of such bands as Eclection, Sailor and Noir (with Tim Dry of the robotic/music duo Tik and Tok). After the break-up of Sailor in the late 1970s, Kajanus decided to experiment with electronic music and formed DATA, together with vocalists Francesca ("Frankie") and Phillipa ("Phil") Boulter, daughters of British singer John Boulter.

The classically orientated title track of DATA’s first album, Opera Electronica, was used as the theme music to the short film, Towers of Babel (1981), which was directed by Jonathan Lewis and starred Anna Quayle and Ken Campbell. Towers of Babel was nominated for a BAFTA award in 1982 and won the Silver Hugo Award for Best Short Film at the Chicago International Film Festival of the same year.

DATA released two more albums, the experimental 2-Time (1983) and the Country & Western-inspired electronica album Elegant Machinery (1985). The title of the last album was the inspiration for the name of Swedish pop synth group, elegant MACHINERY, formerly known as Pole Position.

Data (word)

The word data has generated considerable controversy on if it is a singular, uncountable noun, or should be treated as the plural of the now-rarely-used datum.

Usage in English

In one sense, data is the plural form of datum. Datum actually can also be a count noun with the plural datums (see usage in datum article) that can be used with cardinal numbers (e.g. "80 datums"); data (originally a Latin plural) is not used like a normal count noun with cardinal numbers and can be plural with such plural determiners as these and many or as a singular abstract mass noun with a verb in the singular form. Even when a very small quantity of data is referenced (one number, for example) the phrase piece of data is often used, as opposed to datum. The debate over appropriate usage continues, but "data" as a singular form is far more common.

In English, the word datum is still used in the general sense of "an item given". In cartography, geography, nuclear magnetic resonance and technical drawing it is often used to refer to a single specific reference datum from which distances to all other data are measured. Any measurement or result is a datum, though data point is now far more common.

Mission (Christianity)

Christian mission is "an organized effort for the propagation of the Christian faith."

Missions often involve sending individuals and groups, called "missionaries," across boundaries, most commonly geographical boundaries, for the purpose of proselytism (conversion to Christianity, or from one Christian tradition to another). This involves evangelism (preaching a set of beliefs for the purpose of conversion), and humanitarian work, especially among the poor and disadvantaged. There are a few different kinds of mission trips: short-term, long-term, relational and ones meant simply for helping people in need. Some might choose to dedicate their whole lives to missions as well. Missionaries have the authority to preach the Christian faith (and sometimes to administer sacraments), and provide humanitarian work to improve economic development, literacy, education, health care, and orphanages. Christian doctrines (such as the "Doctrine of Love" professed by many missions) permit the provision of aid without requiring religious conversion.

South Pasadena station

South Pasadena (formerly Mission) is an at-grade light rail station in the Los Angeles County Metro Rail system. It is located at the intersection of Mission Street and Meridian Avenue in South Pasadena, California. The station is served by the Gold Line.

This station features the adjacent station art sculpture "Astride-Aside" (2003) by artist Michael Stutz. The station has a 122 space park and ride lot and there is a fee to park.

Formerly serving the Atchison, Topeka and Santa Fe railroad, the original depot building was torn down in 1954 with the station's closure. The current structure was built with the reactivation of the line as a light rail station in 2003.

Mission (LDS Church)

A mission of The Church of Jesus Christ of Latter-day Saints (LDS Church) is a geographical administrative area to which church missionaries are assigned. Almost all areas of the world are within the boundaries of an LDS Church mission, whether or not Mormon missionaries live or proselytize in the area. As of July 2015, there are 418 missions of the LDS Church.

Administrative structure

Geographically, a mission may be a city, a city and surrounding areas, a state or province, or perhaps an entire country or even multiple countries. Typically, the name of the mission is the name of the country (or state in the United States), and then the name of the city where the mission headquarters office is located. New missionaries receive a formal mission call, assigning them to a particular mission for the duration of their two years or eighteen months of service. Each mission has, on average, about 150 missionaries serving there.

Mission president

All missionaries serve in a mission under the direction of a mission president, who, like individual missionaries, is assigned by the LDS Church president. The mission president must be a married high priest in the Melchizedek Priesthood; his wife is asked to serve alongside him. In 2013 the mission president's wife was given additional leadership roles in the mission. Mission presidents are typically in their forties or older, and usually have the financial means to devote themselves full-time to the responsibility for three consecutive years. The church provides mission presidents with a minimal living allowance but it normally requires them to supplement it with their own funds. Often, the mission president must learn the local language spoken in the mission, as the missionaries do (although many mission presidents today have either previously served a mission in the mission language or speak the mission language as their native language).
