Stagefright (bug)
–
The phone number is the only target information. The Stagefright bug was discovered by Joshua Drake from the Zimperium security firm, prior to the announcement, Drake reported the bug to Google in April 2015, which incorporated a related bugfix into its internal source code repositories two days after the report. Legerov also confirmed that the vulnerabilities he discovered become unexploitable by applying the patches Drake submitted to Google, on August 13,2015, another Stagefright vulnerability CVE-2015-3864 was published by Exodus Intelligence. This vulnerability was not mitigated by existing fixes of already known vulnerabilities, CyanogenMod team published a notice that patches for CVE-2015-3864 have been incorporated in CyanogenMod 12.1 source on August 13,2015. On October 1,2015, Zimperium released details of further vulnerabilities and this vulnerability affects specially crafted MP3 and MP4 files that execute their payload when played using the Android Media server. The vulnerability has been assigned identifier CVE-2015-6602 and was found in a core Android library called libutils, Android 1.5 through 5.1 are vulnerable to this new attack and it is estimated that one billion devices are affected. While Google maintains the Androids primary codebase, firmware updates for various Android devices are the responsibility of wireless carriers, many of the unmaintained devices would need to be rooted, which violates the terms of many wireless contracts. Therefore, the nature of Stagefright bug highlights the technical and organizational difficulties associated with the propagation of Android patches, members of the ZHA also received source code of the Zimperiums proof-of-concept Stagefright exploit before it was publicly released. As of August 6,2015,25 of the largest Android device OEMs and wireless carriers have joined the ZHA.0 Ice Cream Sandwich, the version of Android 5.1 Lollipop includes patches against the Stagefright bug

Fear
–
Fear in human beings may occur in response to a specific stimulus occurring in the present, or in anticipation or expectation of a future threat perceived as a risk to body or life. The fear response arises from the perception of danger leading to confrontation with or escape from/avoiding the threat, in humans and animals, fear is modulated by the process of cognition and learning. Thus fear is judged as rational or appropriate and irrational or inappropriate, an irrational fear is called a phobia. Watson, Robert Plutchik, and Paul Ekman have suggested there is only a small set of basic or innate emotions. This hypothesized set includes such emotions as acute stress reaction, anger, angst, anxiety, fright, horror, joy, panic, and sadness. Fear is closely related to, but should be distinguished from, the emotion anxiety, the fear response serves survival by generating appropriate behavioral responses, so it has been preserved throughout evolution. Many physiological changes in the body are associated with fear, summarized as the fight-or-flight response and this primitive mechanism may help an organism survive by either running away or fighting the danger. With the series of changes, the consciousness realizes an emotion of fear. People develop specific fears as a result of learning and this has been studied in psychology as fear conditioning, beginning with John B. Watsons Little Albert experiment in 1920, which was inspired after observing a child with a fear of dogs. In this study, an 11-month-old boy was conditioned to fear a white rat in the laboratory, the fear became generalized to include other white, furry objects, such as a rabbit, dog, and even a ball of cotton. Fear can be learned by experiencing or watching a frightening traumatic accident, for example, if a child falls into a well and struggles to get out, he or she may develop a fear of wells, heights, enclosed spaces, or water. There are studies looking at areas of the brain that are affected in relation to fear, when looking at these areas, it was proposed that a person learns to fear regardless of whether they themselves have experienced trauma, or if they have observed the fear in others. In a study completed by Andreas Olsson, Katherine I and this suggests that fear can develop in both conditions, not just simply from personal history. Fear is affected by cultural and historical context, for example, in the early 20th century, many Americans feared polio, a disease that can lead to paralysis. There are consistent cross-cultural differences in how people respond to fear, display rules affect how likely people are to show the facial expression of fear and other emotions. Although many fears are learned, the capacity to fear is part of human nature, many studies have found that certain fears are much more common than others. These fears are also easier to induce in the laboratory and this phenomenon is known as preparedness

Performance
–
A performance, in the performing arts, generally comprises an event in which a performer or group of performers present one or more works of art to an audience. Usually the performers participate in rehearsals beforehand, the means of expressing appreciation can vary by culture. Chinese performers will clap with the audience at the end of a performance, in Japan, folk performing-arts performances commonly attract individuals who take photographs, sometimes getting up to the stage and within inches of performers faces. Sometimes the dividing line between performer and the audience may become blurred, as in the example of theatre where audience members get involved in the production. Theatrical performances can take place daily or at some other regular interval, performances can take place at designated performance spaces, or in a non-conventional space, such as a subway station, on the street, or in somebodys home. Theatrical performances, especially when the audience is limited to only a few observers and this increase takes place in several stages relative to the performance itself, including anticipatory activation, confrontation activation and release period. The same physiological reactions can be experienced in other mediums, such as instrumental performance, heart rate shares a strong, positive correlation with the self reported anxiety of performers. Other physiological responses to public performance include perspiration, secretion of the adrenal glands, a performance may also describe the way in which an actor performs. In a solo capacity, it may refer to a mime artist, comedian, conjurer.

Audience
–
An audience is a group of people who participate in a show or encounter a work of art, literature, theatre, music, video games, or academics in any medium. Audience members participate in different ways in different kinds of art, some events invite overt audience participation and others allowing only modest clapping and criticism, media audience studies have become a recognized part of the curriculum. Audience theory offers insight into audiences in general. These insights shape our knowledge of just how audiences affect and are affected by different forms of art, the biggest art form is the mass media. Films, video games, radio shows, software, and other formats are affected by the audience and its reviews, in the age of easy Internet participation and citizen journalism, professional creators share space, and sometimes attention, with the public. American journalist Jeff Jarvis said, Give the people control of media, the corollary, Dont give the people control of media, and you will lose. Whenever citizens can exercise control, they will, tom Curley, President of the Associated Press, similarly said, The users are deciding what the point of their engagement will be — what application, what device, what time, what place. In rhetoric, some depend on circumstance and situation, and are characterized by the individuals that make up the audience. Sometimes these audiences are subject to persuasion and engage with the ideas of the speaker, ranging in size and composition, this audience may come together and form a composite of multiple groups. An immediate audience is a type of audience that is composed of individuals who are subjects with a speaker. This audience directly listens to, engages with, and consumes the rhetorical text in an unmediated fashion, in measuring immediate audience reception and feedback, one can depend on personal interviews, applause, and verbal comments made during and after a rhetorical speech. In contrast to immediate audiences, mediated audiences are composed of individuals who consume rhetorical texts in a manner that is different from the time or place in which a speaker presents text. Audiences who consume texts or speeches through television, radio and Internet are considered mediated audiences because those mediums separate the rhetor and the audience. In measuring mediated audience reception and feedback, one can depend on opinion polls and ratings, as well as comments, theoretical audiences are imagined for the purpose of helping a speaker compose, practice, or a critic to understand, a rhetorical text or speech. The universal audience is an audience that serves as an ethical. The concept of the audience has received criticism for being idealistic because it can be considered as an impediment in achieving persuasive effect with particular audiences. Yet, it still may be useful as a guide for a speaker. An ideal audience is an imagined, intended audience

Camera
–
Thumb|A2016 Nikon D810 A camera is an optical instrument for recording or capturing 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 camera is a remote sensing device as it senses subjects without physical contact. The word camera comes from camera obscura, which means dark chamber and is the Latin name of the 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. A camera may work with the light of the spectrum or with other portions of the electromagnetic spectrum. A still camera is a device which creates a single image of an object or scene. All cameras use the basic design, light enters an enclosed box through a converging lens/convex lens. A shutter mechanism controls the length of time that light can enter the camera, a display, often a liquid crystal display, permits the user to view scene to be recorded and settings such as ISO speed, exposure, and shutter speed. A movie camera or a video camera operates similarly to a camera, except it records a series of static images in rapid succession. When the images are combined and displayed in order, the illusion of motion is achieved, the forerunner to the photographic camera was the camera obscura. The oldest known record of this principle is a description by Han Chinese philosopher Mozi, Mozi correctly asserted that the camera obscura image is inverted because light travels in straight lines from its source. In the 11th century Arab physicist Ibn al-Haytham s wrote very influential essays about experiments with light through an opening in a darkened room. The use of a lens in the opening of a wall or closed window shutter of a room to project images used as a drawing aid has been traced back to circa 1550. Since the late 17th century portable camera obscura devices in tents, before the development of the photographic camera, it had been known for hundreds of years that some substances, such as silver salts, darkened when exposed to sunlight. The first person to use this chemistry to create images was Thomas Wedgwood, to create images, Wedgwood placed items, such as leaves and insect wings, on ceramic pots coated with silver nitrate, and exposed the set-up to light. These images werent permanent, however, as Wedgwood didnt employ a fixing mechanism and he ultimately failed at his goal of using the process to create fixed images created by a camera obscura. The first permanent photograph of an image was made in 1826 by Joseph Nicéphore Niépce using a sliding wooden box camera made by Charles. Niépce had been experimenting with ways to fix the images of a camera obscura since 1816, the photograph Niépce succeeded in creating shows the view from his window
