Camera

A camera is an optical instrument for recording images, which may be stored locally, transmitted to another location, or both. The images may be individual still photographs or sequences of images constituting videos or movies. The word camera comes from camera obscura, which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface. The modern photographic camera evolved from the camera obscura. The functioning of the camera is very similar to the functioning of the human eye.

Functional description

A camera may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A still camera is an optical device which creates a single image of an object or scene, and records it on an electronic sensor or photographic film. All cameras use the same basic design: light enters an enclosed box through a converging lens and an image is recorded on a light-sensitive medium. A shutter mechanism controls the length of time that light can enter the camera. Most photographic cameras have functions that allow a person to view the scene to be recorded, allow for a desired part of the scene to be in focus, and to control the exposure so that it is not too bright or too dim. A display, often a liquid crystal display (LCD), permits the user to view scene to be recorded and settings such as ISO speed, exposure, and shutter speed.

Generic top-level domain

Generic top-level domains (gTLDs) are one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. A top-level domain is the last label of every fully qualified domain name. They are called generic for historic reasons; initially, they were contrasted with country-specific TLDs in RFC 920.

The core group of generic top-level domains consists of the com, info, net, and org domains. In addition, the domains biz, name, and pro are also considered generic; however, these are designated as restricted, because registrations within them require proof of eligibility within the guidelines set for each.

Historically, the group of generic top-level domains included domains, created in the early development of the domain name system, that are now sponsored by designated agencies or organizations and are restricted to specific types of registrants. Thus, domains edu, gov, int, and mil are now considered sponsored top-level domains, much like the themed top-level domains (e.g., jobs). The entire group of domains that do not have a geographic or country designation (see country-code top-level domain) is still often referred to by the term generic TLDs.

Camera (cephalopod)

Camerae (singular camera) are the spaces or chambers enclosed between two adjacent septa in the phragmocone of a nautiloid or ammonoid cephalopod. These can be seen in cross-sections of a nautilus shell and in the polished cross-sections of ammonites. In life these chambers are filled with gas, mediated by the siphuncle, and used to control buoyancy.

Some Palaeozoic nautiloid genera, especially those with long, straight shells, are distinguished by cameral deposits. These were accumulations of calcium carbonate secreted in the empty chambers of the shell, used for ballast and control of buoyancy. The nature and form of these deposits are very useful in nautiloid classification.

.africa

.Africa is the proposed Internet generic Top-Level Domain (gTLD) for the African and Pan African communities and users wherever they may reside. The .africa gTLD serves as a regional domain for individuals and entities based in and out of Africa.

Status

The .Africa gTLD has not yet been delegated to any organization as registry operator. The .Africa application that was submitted by DotConnectAfrica Trust is now the subject of an unresolved disagreement with ICANN (DCA Trust vs ICANN) following an Independent Review Panel (IRP) Process that was invoked by DCA Trust under ICANN’s accountability mechanism in October 2013. The IRP was administrated by the International Center for Dispute Resolution (ICDR) of the American Arbitration Association (AAA) New York, US.

DCA Trust had passed all the new gTLD applicant evaluation criteria, but before the Initial Evaluation (IE) result was issued, a Governmental Advisory Committee GAC Objection Advice that had been issued in Beijing in April 2013 was later accepted by the ICANN Board in early June 2013 which caused the ICANN Board to instruct ICANN staff that DCA Trust’s .Africa new gTLD application will not be approved. This had caused the non-completion of the evaluation of DCA Trust’s application; which then led DCA Trust to challenge the ICANN Board decision through a series of accountability mechanism.

Africa (Petrarch)

Africa is an epic poem in Latin hexameters by the 14th century Italian poet Petrarch (Francesco Petrarca). It tells the story of the Second Punic War, in which the Carthaginian general Hannibal invaded Italy, but Roman forces were eventually victorious after an invasion of north Africa led by Publius Cornelius Scipio Africanus, the epic poem's hero.

Background

Africa and De viris illustribus were partially inspired by Petrarch's visit to Rome in 1337. According to Bergin and Wilson (p. ix). It seems very likely that the inspirational vision of the Eternal City must have been the immediate spur to the design of the Africa and probably De viris illustribus as well. After returning from his grand tour, the first sections of Africa were written in the valley of Vaucluse. Petrarch recalls

The fact that he abandoned it early on is not entirely correct since it was far along when he received two invitations (from Rome and from Paris) in September 1340 each asking him to accept the crown as poet laureate. A preliminary form of the poem was completed in time for the laurel coronation April 8, 1341 (Easter Sunday).

Africa (Karl Wolf song)

Africa is the first official single by Lebanese Canadian singer Karl Wolf from his second studio album Bite The Bullet. The album version of the song features rapper/reggae artist Culture. The song is inspired by the worldwide hit "Africa" by Toto and samples music and covers lyrics from the chorus from the original version, providing new lyrics in place of the original's verses.

Music video

Despite the African title of the song, the music video was actually shot off the shore of Dibba, Oman. The music video for "Africa" starts off with Wolf at his secret island resort on his laptop. He gets a call with the ringtone for "Desensitize" (an earlier hit by Karl Wolf featuring Culture). Culture is on the phone informing Wolf that he is on a boat and heading toward shore to meet up with Wolf.

In the next scene, Wolf sees a sexy woman in a bikini on the beach and starts talking to her. Some other scenes in the video also take place at nighttime with Wolf, Culture, and the same sexy woman in a yellow bikini around a fireplace.
