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.
Randomness is the lack of pattern or predictability in events. A random sequence of events, symbols or steps has no order and does not follow an intelligible pattern or combination. Individual random events are by definition unpredictable, but in many cases the frequency of different outcomes over a large number of events (or "trials") is predictable. For example, when throwing two dice, the outcome of any particular roll is unpredictable, but a sum of 7 will occur twice as often as 4. In this view, randomness is a measure of uncertainty of an outcome, rather than haphazardness, and applies to concepts of chance, probability, and information entropy.
The fields of mathematics, probability, and statistics use formal definitions of randomness. In statistics, a random variable is an assignment of a numerical value to each possible outcome of an event space. This association facilitates the identification and the calculation of probabilities of the events. Random variables can appear in random sequences. A random process is a sequence of random variables whose outcomes do not follow a deterministic pattern, but follow an evolution described by probability distributions. These and other constructs are extremely useful in probability theory and the various applications of randomness.
"Random" is the first CD single from UK hip hop artist Lady Sovereign, following the release of her 12" vinyl single "Ch Ching (Cheque 1 2)" in 2004. It was her second and last single for Casual Records in 2005.
The single was Lady Sovereign's first to make the UK top 75, peaking at #73 there and spending one week within the top 75. After the single release, she was signed by Def Jam Recordings and this single is considered to be her breakthrough into the mainstream market.
"Random" was featured on an episode of The O.C. aired on April 27, 2006, playing in the background during the senior prom in Season 3, Episode 23 - "The Party Favor" and was featured as a track on Midnight Club 3: DUB Edition Remix. A remix of this song was played on the "Jamalot" episode of CSI: NY.
The first rapped line in the song references the hit song "Tipsy" by J-Kwon.
The Remixes - 12" Promo single
E'rybody in the club gettin' tipsy
Oh, f*** that, just whine like a gypsy
Can't see straight like I got one eye
Your bottle opener or mine?
Let's get started
Move ya arms 'round like f***ed up karate
Ohh, s***, my word play's nasty
Ohh, s***, don't put it past me
Move, titch, get out the way
Now enough of that, I'm here to stay
Flow lazy
Pick the pace up when I flow less hazy
J-Lo's got a batty
Well, you can't see mine
'Cause I wear my trousers baggy
Anyways, yeah, let's commence
Everybody get random, all gyal them, all man them
Everybody get random, just do somethin' random
Everybody get random, all gyal them, all man them
Sovereign get random, just do somethin' random
Smokin' kills and so do my lyrics
If you're poppin' pills then trust you're not with it
'Cause I got the skills and I'm over the limit
Dishin' lyrics like meals every second every minute
Ding, dong, special delivery
Biggest midget in the game, can't get rid of me
Give me just a minute and I'll in be your vicinity
My words hurt you just like losin' virginity
Well, I'm right there
Naw, tell a lie 'cause I'm right there
Right hurr, nah, right here
Now get off your churr, I mean chair
Some English MC's get it twisted
Start sayin' cookies instead of biscuits
Anyways, yeah, let's commence
Everybody get random, all gyal them, all man them
Everybody get random, just do somethin' random
Everybody get random, all gyal them, all man them
Everybody get random, just do somethin' random
Everybody get random, all gyal them, all man them
Everybody get random, just do somethin' random
Everybody get random, all gyal them, all man them
Sovereign get random, just do somethin' random
Yo, get up and do somethin' random
Yo, watch it now
One, two, Sov is comin' for you
Three, four, better lock your door
Five, six, well I'm full of tricks
So everybody come and vibe with the little titch
Switch
Just check how my flow differs
I'm droppin' lyrics like a hole droppin' knickers
I'm on a whole other level, I'm old school
Like [Incomprehensible], fry up the Snickers
This s***'s hot, where the sniffer though?
Let's get random, zagga, zagga, zagga, yo
You wanna come and test me, well, bring it on
This is the new ting, the new sing along
S O V
