Imperativ (internationally released as Imperative) is a 1982 German drama film written and directed by Krzysztof Zanussi.
The film entered the competition at the 39th Venice International Film Festival, where it received the Special Jury Prize.
In computer science, imperative programming is a programming paradigm that uses statements that change a program's state. In much the same way that the imperative mood in natural languages expresses commands, an imperative program consists of commands for the computer to perform. Imperative programming focuses on describing how a program operates.
The term is often used in contrast to declarative programming, which focuses on what the program should accomplish without specifying how the program should achieve the result.
Procedural programming is a type of imperative programming in which the program is built from one or more procedures (also known as subroutines or functions). The terms are often used as synonyms, but the use of procedures has a dramatic effect on how imperative programs appear and how they are constructed. Heavily-procedural programming, in which state changes are localized to procedures or restricted to explicit arguments and returns from procedures, is known as structured programming. From the 1960s onwards, structured programming and modular programming in general have been promoted as techniques to improve the maintainability and overall quality of imperative programs. Object-oriented programming extends this approach.
I81B4U was an oddly named EP from Boston hardcore punk / speed metal band, Gang Green. It was released in 1988, after the previous year's debut for Roadrunner Records, You Got It and before 1989's release, Older... Budweiser.
The title is a reference to Van Halen's album, OU812 released in the same year. I81B4U translates phonetically to "I Ate One Before You".
The release of this EP compounded the band's position comfortably occupying the ground between hardcore punk and speed metal – known as crossover thrash in some circles, too.
Five short and fast songs featured the band's trademark melodic mutant rock and roll style, with "Bartender" and "Lost Chapter" emerging as the stand-out tracks in all their live sets since. Sing-along choruses and memorable riffs, coupled with capable guitar solos, kept both camps happy – but perhaps leaving the hardcore punk fans of theirs wondering what was coming next.
Tracks 3 and 5 displayed the band's other hobbies – other than drinking Budweiser – the love of loose women. The lyrics, including titles, were straight out of the AC/DC sexual innuendo handbook.
