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.
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.
Second wine (or second label; in French Second vin) is a term commonly associated with Bordeaux wine to refer to a second label wine made from cuvee not selected for use in the Grand vin or first label. In some cases a third wine or even fourth wine is also produced. Depending on the house winemaking style, individual plots of a vineyard may be selected, often those of the youngest vines, and fermented separately, with the best performing barrels being chosen for the house's top wine and the other barrels being bottled under a separate label and sold for a lower price than the Grand vin.
In less favorable vintages, an estate may choose to release only a second label wine rather than to release a smaller than normal quantity of its Grand vin or a wine that would not be consistent with past vintages under that name. The practice has its roots in the 18th century but became more commercially prominent in the 1980s when consumers discovered these wines as a more affordable way to drink the product of a First growth or classified Bordeaux estate without paying the premium for the estate's label and classification.
In deliberative bodies a second to a proposed motion is an indication that there is at least one person besides the mover that is interested in seeing the motion come before the meeting. It does not necessarily indicate that the seconder favors the motion.
The purpose of requiring a second is to prevent time being wasted by the assembly's having to dispose of a motion that only one person wants to see introduced. Hearing a second to a motion is guidance to the chair that he should state the question on the motion, thereby placing it before the assembly. It does not necessarily indicate that the seconder favors the motion.
The seconder may state "I second the motion" or "second" without first being recognized by the chair. He may remain seated but in larger assemblies, especially in those where nonmembers may be seated in the hall, the seconder should stand. After hearing a second, the chair then states the question and the motion is placed before the assembly for discussion.

Noelia Lorenzo Monge (born in San Juan), mostly known as Noelia, is an international Puerto Rican pop EDM singer who rose to fame in 1999.
Her self-titled debut album was certified as a RIAA gold album in the United States. During her career she has had ten Latin Billboard Top 40 hits and Five Top 40 Billboard Dance/Club Play Songs. She is a Latin Billboard Award Winner.
Noelia started working on her first full-length album in 1998. The self-titled album was finally released in 1999, making her debut at the Madison Square Garden. The album produced the hit single "Tu", written by Estéfano. In total, Noelia has sold almost 5 million albums worldwide, including almost 1 million copies in the U.S. from her debut album that was certified gold by in the U.S.
In 2000 she released her second album, Golpeando Fuerte. Her third album, Natural, released in 2003 featured another hit song, "Clávame Tu Amor", which peaked at #5 on Billboard Hot Latin Tracks. The album also featured songwriting contributions from Latin Producer Kike Santander and Jose Gaviria.
Spell is the standard English language spell checker for Unix.
Appearing in Version 7 Unix,spell was originally written by Stephen C. Johnson of Bell Labs in 1975. Douglas McIlroy later improved its accuracy, performance, and memory use, and described his work and spell in general in his 1982 paper "Development of a Spelling list".
Spell has a simple command-line interface: It goes over all the words in a given text file, and prints a sorted list of unique misspelled words in that file. It does not provide any interface for looking for those words in the file, or helping to correct the mistakes. In 1983, a different spell-checker, ispell (the interactive spell-checker), was ported to Unix. ispell had a user interface for showing the spelling mistakes in context and suggesting how to correct them. Since then, the original Spell tool has been mostly considered obsolete.
Another reason Spell is considered obsolete is that it only supports the English language. Modern spell-checkers for Unix and Linux systems, such as aspell, MySpell and hunspell, support a multitude of different languages and character sets. The Single Unix Specification has officially declared Spell a "legacy application", stating that this was done "because there is no known technology that can be used to make it recognise general language for user-specified input without providing a complete dictionary along with the input file." Nevertheless, the Single Unix Specification does not standardize any other spell-checking utility to take Spell's place.
