Lucid (programming language)

Lucid is a dataflow programming language. It is designed to experiment with non-von Neumann programming models. It was designed by Bill Wadge and Ed Ashcroft and described in the book Lucid, the Dataflow Programming Language.

Model

Lucid uses a demand-driven model for data computation. Each statement can be understood as an equation defining a network of processors and communication lines between them through which data flows. Each variable is an infinite stream of values and every function is a filter or a transformer. Iteration is simulated by 'current' values and 'fby' (read as 'followed by') operator allowing composition of streams.

Lucid is based on an algebra of histories, a history being an infinite sequence of data items. Operationally, a history can be thought of as a record of the changing values of a variable, history operations such as first and next can be understood in ways suggested by their names. Lucid was originally conceived as a kind of very disciplined, mathematically pure, single-assignment language, in which verification would be very much simplified. However, the dataflow interpretation has been a very important influence on the direction in which Lucid has evolved.

Return (2011 film)

Return is a 2011 independent film about an American reservist, wife and mother returning home from her tour of duty in the Middle East. The film was written and directed by Liza Johnson, and stars Linda Cardellini, Michael Shannon and John Slattery. It is Johnson's first feature-length film, and received good reviews at its premiere at the Cannes Film Festival Directors' Fortnight.

Synopsis

Kelli, returning from her military tour of duty in the Middle East, has high hopes for resuming her old life in her midwestern hometown. Her hopes are gradually dashed as her relationships with her family and friends suffer; they have moved on, and she cannot adjust. She is unable to provide the attention her children need, she quits her dull factory job, she discovers her husband Mike's infidelity, drinks with her friends, then is stopped by the police while driving under the influence. During her court-ordered therapy session, she meets Bud, a charming war veteran. She undergoes a gradual breakdown, but persists in her efforts to reestablish her life.

Returning

In retail, a return is the process of a customer taking previously purchased merchandise back to the retailer, and in turn receiving a refund in the original form of payment, exchange for another item (identical or different), or a store credit.

Many retailers will accept returns provided that the customer has a receipt as a proof of purchase, and that certain other conditions, which depend on the retailer's policies, are met. These may include the merchandise being in a certain condition (usually resellable if not defective), no more than a certain amount of time having passed since the purchase, and sometimes that identification be provided (though usually only if a receipt is not provided). In some cases, only exchanges or store credit are offered, again usually only without a receipt, or after an initial refund period has passed. Some retailers charge a restocking fee for non-defective returned merchandise, but typically only if the packaging has been opened.

While retailers are not usually required to accept returns, laws in many places require retailers to post their return policy in a place where it would be visible to the customer prior to purchase.
