Code

In communications and information processing, code is a system of rules to convert information—such as a letter, word, sound, image, or gesture—into another form or representation, sometimes shortened or secret, for communication through a channel or storage in a medium. An early example is the invention of language, which enabled a person, through speech, to communicate what he or she saw, heard, felt, or thought to others. But speech limits the range of communication to the distance a voice can carry, and limits the audience to those present when the speech is uttered. The invention of writing, which converted spoken language into visual symbols, extended the range of communication across space and time.

The process of encoding converts information from a source into symbols for communication or storage. Decoding is the reverse process, converting code symbols back into a form that the recipient understands.

One reason for coding is to enable communication in places where ordinary plain language, spoken or written, is difficult or impossible. For example, semaphore, where the configuration of flags held by a signaller or the arms of a semaphore tower encodes parts of the message, typically individual letters and numbers. Another person standing a great distance away can interpret the flags and reproduce the words sent.

Dress code

Dress codes are written and, more often, unwritten rules with regard to clothing. Clothing like other aspects of human physical appearance has a social significance, with different rules and expectations being valid depending on circumstance and occasion.

The dress code has built in rules or signals indicating the message being given by a person's clothing and how it is worn. This message may include indications of the person's gender, income, occupation and social class, political, ethnic and religious affiliation, attitude towards comfort, fashion, traditions, gender expression, marital status, sexual availability, and sexual orientation, etc. Clothes convey other social messages including the stating or claiming personal or cultural identity, the establishing, maintaining, or defying social group norms, and appreciating comfort and functionality.

For example, wearing expensive clothes can communicate wealth, the image of wealth, or cheaper access to quality clothing. All factors apply inversely to the wearing of inexpensive clothing and similar goods. The observer sees the resultant, expensive clothes, but may incorrectly perceive the extent to which these factors apply to the person observed. (cf. conspicuous consumption). Clothing can convey a social message, even if none is intended.

Film festival

A film festival is an organized, extended presentation of films in one or more cinemas or screening venues, usually in a single city or region. Increasingly, film festivals show some films outdoors. Films may be of recent date and, depending upon the festival's focus, can include international and domestic releases. Some festivals focus on a specific film-maker or genre (e.g., film noir) or subject matter (e.g., horror film festivals). A number of film festivals specialise in short films of a defined maximum length. Film festivals are typically annual events. Some film historians do not consider Film Festivals as official releases of film, like Jerry Beck. The best known film festivals are the Venice Film Festival, the Cannes Film Festival, the Toronto Film Festival, Sundance Film Festival, and the Berlin International Film Festival, the latter being the largest film festival worldwide, based on attendance. The Venice Film Festival is the oldest major festival. The Melbourne International Film Festival is the largest film festival in the Southern Hemisphere and one of the oldest in the world. A 2013 study found 3,000 active films festivals worldwide—active defined as having held an event in the previous 24 months.
