Libra is a fictional character, a supervillain appearing in comic books published by DC Comics. He first appeared in Justice League of America #111 (May-June 1974), where he formed the first incarnation of the Injustice Gang (though there had been other villain groups with similar names, like the Injustice Society and the Injustice League). Libra made his return with a leading role in Final Crisis in 2008.

Publication history

Libra's only major appearance, prior to his appearance in Final Crisis, was in Justice League of America #111–112, in 1974. In 2004, he made a brief cameo in the JLA/Avengers crossover (#4) by Kurt Busiek and George Pérez.

Grant Morrison, the writer of Final Crisis, explained the reason for picking an obscure villain:

In May 2008, his appearances were reprinted in DC Universe Special: Justice League of America at the same time as he was reintroduced, along with the Human Flame (a Martian Manhunter foe who appeared in Detective Comics #274), in Justice League of America #21. He returns, apparently retaining the full might of his godlike status, to lead a new and final incarnation of the Secret Society of Super-Villains, this time offering to every villain, from simple costumed crooks to major ones, the realization of his/her fondest wish.

Generator may refer to:

Mathematics

Computing

In category theory in mathematics a family of generators (or family of separators) of a category is a collection of objects, indexed by some set I, such that for any two morphisms in , if then there is some i∈I and morphism , such that the compositions . If the family consists of a single object G, we say it is a generator (or separator).

Generators are central to the definition of Grothendieck categories.

The dual concept is called a cogenerator or coseparator.

Examples

In the category of abelian groups, the group of integers is a generator: If f and g are different, then there is an element , such that . Hence the map suffices.

"Generator" is a Foo Fighters song, released as a single in 2000 from their third album There Is Nothing Left to Lose. The single was only released in Australia and also released as a limited edition single in Europe.

The song is particularly unique among the band's work because of Dave Grohl's implementation of the talk box in parts of the song. The usage of the device was partly inspired by Grohl's admiration of Peter Frampton and Joe Walsh, both of whom helped popularize it in the 1970s.
