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.
CONFIG.SYS
CONFIG.SYS is the primary configuration file for the DOS and OS/2 operating systems. It is a special ASCII text file that contains user-accessible setup or configuration directives evaluated by the operating system during boot. CONFIG.SYS was introduced with DOS 2.0.
Usage
The directives in this file configure DOS for use with devices and applications in the system. The CONFIG.SYS directives also set up the memory managers in the system. After processing the CONFIG.SYS file, DOS proceeds to load and execute the command shell specified in the SHELL line of CONFIG.SYS, or COMMAND.COM if there is no such line. The command shell in turn is responsible for processing the AUTOEXEC.BAT file.
CONFIG.SYS is composed mostly of name=value directives which look like variable assignments. In fact, these will either define some tunable parameters often resulting in reservation of memory, or load files, mostly device drivers and TSRs, into memory.
In DOS, CONFIG.SYS is located in the root directory of the drive from which the system was booted.

Voyage (EP)
Voyage is the first EP by American metalcore band, In Fear and Faith. It was independently produced and released by the band themselves on December 18, 2007.
Background information
Voyage is the only release by In Fear and Faith to feature vocalist, Tyler "Telle" Smith before his departure from the group within the following year. 2008 also marks the year that the band were signed to Rise Records after their attention caught onto Voyage. Its rhythmical melodies and harsh parts impressed the label. The two songs "Live Love Die" and "The Taste of Regret" were re-recorded for their debut full-length, Your World on Fire, which was released in 2009.
The EP was released on a rare independent pressing on CD, but was widely distributed on iTunes where it received over 30,000 song purchases by the end of 2008.

Pathé
Pathé or Pathé Frères (French pronunciation: [pate fʁɛʁ], styled as PATHÉ!) is the name of various French businesses that were founded and originally run by the Pathé Brothers of France starting in 1896. In the early 1900s, Pathé became the world's largest film equipment and production company, as well as a major producer of phonograph records. In 1908, Pathé invented the newsreel that was shown in cinemas prior to a feature film.
Today, Pathé is a major film production and distribution company, owns a great number of cinema chains, across Europe but mainly in France, including 66% of the Les Cinémas Gaumont Pathé a joint venture between Pathé and the Gaumont Film Company, and several television networks across Europe. It is the second oldest still-operating film company in the world, predating Universal Studios and Paramount Pictures, second only to the French Gaumont Film Company studio.
History
The company was founded as Société Pathé Frères (Pathé Brothers Company) in Paris, France on 28 September 1896, by the four brothers Charles, Émile, Théophile and Jacques Pathé. During the first part of the 20th century, Pathé became the largest film equipment and production company in the world, as well as a major producer of phonograph records.
