     DETAILED DESCRIPTION 
     Approaches for Sharing Content 
     Today, people often utilize computing devices (or systems) for a wide variety of purposes. Users can use their computing devices to, for example, interact with one another, access content, share content, and create content. In some cases, content items can include postings from members of a social network. The postings may include text and live content streams, such as images, videos, and audio. The postings may be published to the social network for consumption by others. 
     Under conventional approaches, content may be posted and/or broadcast through a content provider (e.g., social networking system). In one example, a live content stream can include content that is being captured and streamed live by a user (e.g., a broadcaster). For example, the broadcaster can capture and stream an event (e.g., a live video of the broadcaster, concert, speech, etc.) as part of a live content stream. Such events can be captured using computing devices (e.g., mobile devices with audio and video capture capabilities) and/or standalone devices (e.g., video cameras and microphones). A user (e.g., a viewer) operating a computing device can access the live content stream through the content provider. The content provider encodes and provides data corresponding to the live content stream to the user&#39;s computing device over a network (e.g., the Internet) in real-time. The computing device can decode and present the live content stream, for example, through a display screen of the computing device. In general, the live content stream continues to be provided to the user&#39;s computing device until, for example, the broadcaster discontinues broadcasting the live content stream or the user instructs the computing device to stop accessing the live content stream. 
     In some instances, the live content stream may be broadcasted from a standalone camera device that is designed to capture and live stream content. Users, or viewers, can similarly access this live content stream through the content provider using their computing devices. In some instances, these users may interact with the live content stream (e.g., like, comment, etc.) through the content provider. For example, a user may select an option to “like” the live content stream. In general, the broadcaster can access various information describing such events (e.g., likes, comments, etc.) by interacting with the content provider using a computing device separate from the standalone camera device through which the live content stream is being captured and streamed. Such information is generally not accessible using the standalone camera device. In some instances, it can beneficial for such information to be communicated to the broadcaster through the camera device without requiring a separate computing device. Accordingly, such conventional approaches may not be effective in addressing these and other problems arising in computer technology. 
     An improved approach rooted in computer technology overcomes the foregoing and other disadvantages associated with conventional approaches specifically arising in the realm of computer technology. In various embodiments, a camera device can be used to capture and share content through a content provider (e.g., social networking system). For example, the camera device can be placed at a particular location (e.g., theme park ride entrance, office break room, home, etc.). In this example, individuals can interact with the camera device to share content through a content provider, such as the social networking system. For example, in some embodiments, the camera device can capture and provide media content items (e.g., images, videos, looping videos, etc.) to be shared as posts and/or stories through the social networking system. In some embodiments, the camera device can be used to capture live content streams to be broadcasted through the social networking system. In various embodiments, events (e.g., user engagement, interaction, etc.) that relate to content posted or streamed from the camera device can be indicated or confirmed using one or more light sources (e.g., light-emitting diodes or LEDs) installed in the camera device. For example, these light sources may communicate different information by emitting light using various pre-defined illumination patterns (or sequences). These illumination patterns may involve flashing one or more light sources, blinking one or more light sources, illuminating light sources that emit a particular color, and/or illuminating light sources at some brightness level, to name some examples. Many variations are possible. 
       FIG. 1  illustrates an example system  100  including an example content provider module  102 , according to an embodiment of the present disclosure. As shown in the example of  FIG. 1 , the content provider module  102  can include a content upload module  104 , a live stream module  106 , a content module  108 , an interaction module  110 , and a camera feedback module  112 . In some instances, the example system  100  can include at least one data store  118 . A camera device module  152  can interact with the content provider module  102  over one or more networks  150  (e.g., the Internet, a local area network, a cellular network, etc.). The components (e.g., modules, elements, etc.) shown in this figure and all figures herein are examples only, and other implementations may include additional, fewer, integrated, or different components. Some components may not be shown so as not to obscure relevant details. 
     In some embodiments, the content provider module  102  and/or the camera device module  152  can be implemented, in part or in whole, as software, hardware, or any combination thereof. In general, a module as discussed herein can be associated with software, hardware, or any combination thereof. In some implementations, one or more functions, tasks, and/or operations of modules can be carried out or performed by software routines, software processes, hardware, and/or any combination thereof. In some cases, the content provider module  102  or at least a portion thereof can be implemented using one or more computing devices or systems that include one or more servers, such as network servers or cloud servers. In some instances, the content provider module  102  and/or the camera device module  152  can, in part or in whole, be implemented within or configured to operate in conjunction with a social networking system (or service), such as the social networking system  630  of  FIG. 6 . In some instances, the content provider module  102  and/or the camera device module  152  can be, in part or in whole, implemented within or configured to operate in conjunction or be integrated with a client computing device, such as the user device  610  of  FIG. 6 . For example, the content provider module  102  and/or the camera device module  152  can be implemented as or within a dedicated application (e.g., app), a program, or an applet running on a user computing device or client computing system. The application incorporating or implementing instructions for performing some, or all, functionality of the content provider module  102  and/or the camera device module  152  can be created by a developer. The application can be provided to or maintained in a repository. In some cases, the application can be uploaded or otherwise transmitted over a network (e.g., Internet) to the repository. For example, a computing system (e.g., server) associated with or under control of the developer of the application can provide or transmit the application to the repository. The repository can include, for example, an “app” store in which the application can be maintained for access or download by a user. In response to a command by the user to download the application, the application can be provided or otherwise transmitted over a network from the repository to a computing device associated with the user. For example, a computing system (e.g., server) associated with or under control of an administrator of the repository can cause or permit the application to be transmitted to the computing device of the user so that the user can install and run the application. The developer of the application and the administrator of the repository can be different entities in some cases, but can be the same entity in other cases. It should be understood that many variations are possible. 
     The content provider module  102  can be configured to communicate and/or operate with the at least one data store  118 , as shown in the example system  100 . The at least one data store  118  can be configured to store and maintain various types of data. For example, the data store  118  can store information describing various content that has been posted by users of a social networking system and/or by camera devices interacting with the social networking system. In some implementations, the at least one data store  118  can store information associated with the social networking system (e.g., the social networking system  630  of  FIG. 6 ). The information associated with the social networking system can include data about users, social connections, social interactions, locations, geo-fenced areas, maps, places, events, pages, groups, posts, communications, content, feeds, account settings, privacy settings, a social graph, and various other types of data. In some implementations, the at least one data store  118  can store information associated with users, such as user identifiers, user information, profile information, user specified settings, content produced or posted by users, and various other types of user data. 
     The content provider module  102  can be configured to provide users with access to media content items that are posted through a social networking system. In general, a media content item may correspond to an image, text, audio, video, or looping video, to name some examples. For example, a user can interact with an interface that is provided by a software application (e.g., a social networking application) running on a computing device of the user. This interface can include an option for posting, or uploading, media content items to the social networking system. When posting a media content item, the content upload module  104  can be utilized to communicate data describing the media content item from the computing device (e.g., camera device) to the social networking system. The social networking system can then provide the media content item through the social networking system including, for example, in one or more news feeds and/or stories. In some embodiments, the content upload module  104  provides an application programming interface (API) through which content can be uploaded. In such embodiments, a camera device in which the camera device module  152  is implemented can use this application programming interface to post, or upload, media content items to the social networking system. In some embodiments, the content provider module  102  can authenticate the camera device before posting any content received from the camera device. For example, the content provider module  102  may authenticate the camera device based on login credentials (e.g., username and password, cryptographic token, etc.) provided by the camera device module  152 . 
     In some embodiments, users can live stream content through the social networking system. When initiating a live content stream, the live stream module  106  can be utilized to communicate data (e.g., audio data, video data, etc.) corresponding to the content to be streamed live from a computing device and through the social networking system. In some embodiments, this computing device can be a camera device in which the camera device module  152  is implemented. The live stream module  106  can utilize any generally known techniques that allow for live streaming of content including, for example, the Real Time Messaging Protocol (RTMP). In various embodiments, the computing device from which the live content stream is being provided can be equipped to capture data (e.g., video data, audio data, etc.) corresponding to the live content stream. In some embodiments, the live stream module  106  can publish live content streams being broadcasted through the social networking system in various news feeds. 
     In some embodiments, users can access content provided by the camera device module  152  (e.g., media content items, live content streams) using the content module  108 . For example, the content module  108  can include content in a user&#39;s news feed. Such content may include on-demand media content items (e.g., video on-demand or “VOD”) as well as content that is being streamed live. In this example, the user can access content while browsing the news feed. In another example, the user can access content by performing searches through the social networking system. For example, the user can search for a given media content item, for a user that posted a media content item, and/or for search terms that correspond to a media content item. In another example, the user may select an option to view a live content stream and, in response, the social networking system can send data corresponding to the live content stream to a computing device of the user. In this example, the social networking system can continue sending data corresponding to the live content stream until, for example, the broadcaster of the live content stream discontinues streaming or if the user selects an option to discontinue playback of the live content stream. 
     In some embodiments, when a user accesses a media content item or live content stream, the accessed content is presented through a display screen of the user&#39;s computing device. In some embodiments, the user can select a number of options to provide various types of feedback for media content items and/or live content streams. For example, a user may want to endorse, or “like”, a media content item. In this example, the user can select a “like” option provided in the interface to like, or endorse, the media content item. The interaction module  110  can determine when a user likes a given media content item and can store information describing this relationship. In some embodiments, the interface includes a set of options for reacting to content being presented in the media content item. These options can include a “love” (or “heart”) reaction option, a “haha” (or funny) reaction option, a “wow” (or surprised) reaction option, a “sad” reaction option, and an “angry” reaction option, to name some examples. Similarly, the interaction module  110  can determine when a user selects a reaction option in response to a given media content item and can store information describing this relationship. The interaction module  110  can also determine when other forms of user interaction are performed and can store information describing such interactions (e.g., information describing a type of interaction, an identity of the user, an identity of a broadcaster, and an identifier for the media content item, to name some examples). For example, a viewer may want to post a comment in response to a live content stream. In this example, the viewer can select an option provided in the interface to enter and post the comment for the desired live content stream. The interaction module  110  can determine when a viewer posts a comment in response to a given live content stream and can store information describing this relationship. In some embodiments, the interaction module  110  can determine when users share content (e.g., media content items, live content streams) with other users and can store information describing such relationships. Many variations are possible. 
     In various embodiments, events that occur in response to content that is posted or streamed from the camera device module  152  can be confirmed (or indicated) visually by the camera device in which the camera device module  152  is implemented. For example, in some embodiments, the camera feedback module  112  can be configured to provide the camera device module  152  with instructions for communicating various types of information using one or more light sources (e.g., light-emitting diodes or LEDs). These light sources can be installed in, or otherwise associated with, the camera device in which the camera device module  152  is implemented. The types of events that can be confirmed using the light sources can vary. For example, in some embodiments, the light sources can be used to provide visual confirmation (or indication) of user engagement with content that is posted or streamed by the camera device module  152 . Such user engagement can involve a user accessing the content, a user joining a live content stream, or a user exiting a live content stream, to name some examples. In some embodiments, the light sources can be used to provide visual confirmation of user interactions with content that is posted or streamed by the camera device module  152 . Such user interactions can include a user liking the content, a user posting comments in response to the content, or a user reacting to the content, to name some examples. More details regarding the camera feedback module  112  will be provided below with reference to  FIG. 2 . 
     In various embodiments, the camera device module  152  can be configured to capture and provide content to be published through the content provider module  102 . For example, the camera device module  152  can provide captured media content items (e.g., images, videos, looping videos, etc.) to the content provider module  102  over the network  150  for publication. In another example, the camera device module  152  can provide a live content stream to the content provider module  102  over the network  150  for broadcasting. As yet a further example, the camera device module  152  can manage illumination of lights sources to provide feedback to a broadcaster or other persons depicted in media content items captured by a camera device associated with the light sources. In some embodiments, the camera device module  152  can be implemented as a software application running on a computing device (e.g., camera device). More details regarding the camera device module  152  will be provided below with reference to  FIG. 3 . 
       FIG. 2  illustrates an example of a camera feedback module  202 , according to an embodiment of the present disclosure. In some embodiments, the camera feedback module  112  of  FIG. 1  can be implemented as the camera feedback module  202 . As shown in  FIG. 2 , the camera feedback module  202  can include a publication module  204 , a recognition module  206 , an audience module  208 , and an interaction module  210 . 
     The publication module  204  can be configured to determine when content captured and provided by a camera device has been published through a content provider (e.g., social networking system). In various embodiments, the camera device can implement the camera device module  152  of  FIG. 1 . For example, the camera device may capture and provide one or more media content items to be posted through the social networking system. In this example, the publication module  204  can determine when the media content items have successfully been posted through the social networking system. In some embodiments, the publication module  204  can instruct the camera device to illuminate one or more light sources associated with the camera device in response to the media content items being posted. In some embodiments, the light sources are illuminated based on a pre-defined pattern (or sequence) to provide visual confirmation of the media content items being posted through the social networking system. For example, one or more of the light sources can flash (or blink) to visually confirm the posting. 
     In some embodiments, the camera device may capture and provide a live content stream to be broadcasted through the social networking system. In such embodiments, the publication module  204  can determine when the live content stream is actively being broadcasted through the social networking system. In some embodiments, the publication module  204  can instruct the camera device to illuminate one or more light sources associated with the camera device in response to the live content stream being broadcasted. These light sources can be illuminated based on a pre-defined pattern (or sequence) to visually confirm the broadcasting. For example, one or more of the light sources can blink during an on-going broadcast of the live content stream. In some embodiments, the publication module  204  can instruct the camera device to discontinue illuminating the light sources when broadcasting of the live content stream ceases. 
     The recognition module  206  can be configured to analyze content that is captured and provided by the camera device to determine identities of individuals represented in the captured content. For example, the recognition module  206  can apply generally known face recognition techniques to identify an individual represented in the captured content. In some embodiments, when an individual is recognized, the recognition module  206  can instruct the camera device to illuminate one or more light sources associated with the camera device based on a pre-defined pattern (or sequence) to visually confirm the recognition. For example, a broadcaster may be represented in a live content stream being captured and provided by the camera device. In this example, one or more light sources associated with the camera device can flash to visually confirm identification of the broadcaster. 
     The audience module  208  can be configured to determine corresponding audience information for live content streams being captured and provided by the camera device. In some embodiments, the audience module  208  can determine an audience size for a given live content stream. In such embodiments, the audience module  208  can determine a count of users (or viewers) that are accessing the live content stream through the social networking system at some point in time. In some embodiments, the audience module  208  can instruct the camera device to illuminate one or more light sources associated with the camera device based on a pre-defined pattern (or sequence) to visually indicate the audience size. For example, the camera device can be instructed to illuminate a first light source when the audience size satisfies a first threshold (e.g., 10 viewers). Further, the camera device can be instructed to illuminate both the first light source and a second light source when the audience size corresponds to a second threshold (e.g., 50 viewers). In such embodiments, additional light sources can similarly be illuminated as the audience size increases to satisfy additional thresholds. In another example, the camera device can be instructed to illuminate a light source at a first brightness level when the audience size satisfies a first threshold. Similarly, the camera device can be instructed to illuminate the light source at a second brightness level when the audience size satisfies a second threshold. Many variations are possible. 
     In some embodiments, some of the light sources associated with the camera device can be arranged to represent a particular shape. For example, in some embodiments, some of the light sources can be arranged to represent a circular, or ring, shape. In such embodiments, light sources included in this circular shape can individually be illuminated to indicate the audience size. For example, the camera device can be instructed to illuminate a first light source arranged in the circular shape when the audience size satisfies a first threshold (e.g., 50 viewers). Further, the camera device can be instructed to illuminate both the first light source and a second light source arranged in the circular shape when the audience size satisfies a second threshold (e.g., 100 viewers). In some embodiments, some of the light sources associated with the camera device can be arranged to represent a particular reaction or emoji (e.g., happy face, sad face, etc.). In such embodiments, light sources corresponding to a given reaction can be illuminated when users of the social networking system select an option corresponding to that reaction. 
     In some embodiments, the audience module  208  can be configured to determine when a user (or viewer) joins, or accesses, a live content stream through the social networking system. In such embodiments, the audience module  208  can instruct the camera device to illuminate one or more light sources associated with the camera device based on a pre-defined pattern (or sequence) to provide visual confirmation of a user joining the live content stream. In some embodiments, the audience module  208  can be configured to determine when a user (or viewer) exits, or discontinues accessing, a live content stream through the social networking system. In such embodiments, the audience module  208  can instruct the camera device to illuminate one or more light sources associated with the camera device based on a pre-defined pattern (or sequence) to provide visual confirmation of a user exiting the live content stream. 
     The interaction module  210  can be configured to determine when users interact with content (e.g., media content items, live content streams) that is captured and provided by the camera device. In some embodiments, the interaction module  210  can be configured to determine when a user (or viewer) likes, or endorses, the content through the social networking system. In such embodiments, the interaction module  210  can instruct the camera device to illuminate one or more light sources associated with the camera device based on a pre-defined pattern (or sequence) to provide visual confirmation of a user liking the content. For example, the camera device may be instructed to illuminate one or more light sources that emit a particular color to indicate a user has liked content being captured and provided by the camera device. The interaction module  210  can also instruct the camera device to illuminate the light sources to visually confirm other types of user interactions including, for example, posting a comment in response to the content, sharing the content, and reacting to the content. For example, the interaction module  210  can instruct the camera device to illuminate one or more light sources associated with the camera device based on a pre-defined pattern (or sequence) to provide visual confirmation of a user posting a comment in response to the content provided by the camera device. In some embodiments, light sources can be illuminated at varying levels of brightness to indicate the volume of user interactions received for the content over some period of time. For example, a light source may illuminate at a first brightness level to indicate an a first threshold number of likes (e.g., an individual like). Similarly, the light source may illuminate at a second brightness level to indicate a second threshold number of likes (e.g., 10 likes). Further, the light source may illuminate at a third brightness level to indicate a third threshold number of likes (e.g., 100 likes). 
     In some embodiments, the interaction module  210  can instruct the camera device to illuminate light sources only when certain users interact with the content. For example, in some embodiments, the light sources may only be illuminated in response to interactions (e.g., likes, comments, etc.) from users that are followers (or friends) of a user posting (or broadcasting) the content. In some embodiments, the light sources may only be illuminated in response to interactions from users whose social coefficient score with respect to the user posting (or broadcasting) the content satisfies a threshold. In general, a social coefficient score can be used to measure the strength of a social relationship between a pair of users. In some embodiments, the light sources may only be illuminated in response to interactions from users that have been endorsed by the social networking system. For example, the light sources may illuminate in response to interactions by users that have been labeled as experts or celebrities by the social networking system. 
       FIG. 3  illustrates an example of a camera device module  302 , according to an embodiment of the present disclosure. In some embodiments, the camera device module  152  of  FIG. 1  can be implemented as the camera device module  302 . As shown in  FIG. 3 , the camera device module  302  can include a capture module  304 , a post module  306 , a live stream client module  308 , a capture feedback module  310 , and an illumination feedback module  312 . 
     In various embodiments, the camera device module  302  can be implemented in a camera device that is capable of capturing and storing subject matter as media content items (e.g., images, videos, looping videos, etc.). The camera device can also be configured to interact with a social networking system (e.g., the content provider module  102  of  FIG. 1 ) through which captured media content items can be published. In some embodiments, the camera device module  302  can also provide a live broadcasting option that can be selected to broadcast live content streams through the social networking system. In some instances, the camera device can be installed at a fixed geographic location or point of interest. 
     The capture module  304  can be configured to capture various subject matter using the camera device. Such subject matter can be stored as media content items (e.g., images, videos, looping videos, etc.). In some embodiments, the capture module  304  can be instructed to capture media content items based on user commands applied to the camera device. For example, the camera device can be equipped with options (e.g., buttons) which, when selected, cause the capture module  304  to capture subject matter using the camera device. In some embodiments, the camera device can be configured to automatically capture media content items without manual commands or prompting. For example, the capture module  304  can be configured to periodically (or continuously) evaluate subject matter positioned within a viewfinder of the camera device. During evaluation, the capture module  304  can determine whether the subject matter satisfies any conditions for automatically capturing media content items. For example, a condition for automatically capturing media content items may require that a threshold number of individuals (e.g., one or more individuals) be positioned within the viewfinder of the camera device. In this example, the camera device can be instructed to capture one or more media content items once a threshold number of individuals are detected within the viewfinder. In another example, a condition for automatically capturing content may require that one or more individuals positioned within the viewfinder be smiling or otherwise exhibit a particular expression. In this example, the camera device can automatically capture one or more media content items once individuals detected within the viewfinder are determined to be smiling. In yet another example, a condition for automatically capturing content may require that one or more individuals positioned within the viewfinder are looking at the camera device. In this example, the camera device can be instructed to capture one or more media content items once individuals detected within the viewfinder are determined to be gazing at the camera device. Many variations are possible. 
     In various embodiments, the capture module  304  can use one or more trained machine learning models to evaluate captured subject matter. For example, a machine learning model (image classifier) can be trained to identify features that are represented in captured subject matter. These features can include identities, or names, of individuals, objects, activities, facial expressions, gaze direction, and moods, to name some examples. Such features can be used by the capture module  304  to determine when to automatically capture content. In some embodiments, when storing captured subject matter as a media content item, the capture module  304  can associate the media content item with information describing features that were detected in the captured subject matter. For example, a media content item (e.g., image) of an individual may be associated with detected information indicating the individual&#39;s name (or username), facial expression, mood, and geographic location. 
     The post module  306  can be configured to post media content items captured by the camera device. In general, media content items may be posted in user-specific content feeds or stories. For example, in some embodiments, a media content item in which a first user is represented can be posted in a content feed associated with the first user and/or respective content feeds of users that are followers (or friends of) the first user. 
     In some embodiments, the camera device module  302  can provide an option to broadcast live content streams through the social networking system. When this option is selected, the live stream client module  308  can interact with the live stream module  106  of  FIG. 1  for purposes of streaming live content captured by the camera device module  302 . The live stream client module  308  can implement any generally known techniques that allow for live streaming of content including, for example, the Real Time Messaging Protocol (RTMP). 
     As mentioned, in various embodiments, the camera device includes a set of light sources (e.g., light-emitting diodes or LEDs) that can be used to communicate various information. For example, in some embodiments, the capture feedback module  310  can cause one or more light sources associated with the camera device to illuminate based on a pre-defined pattern (or sequence) to visually simulate a countdown before the camera device captures content (e.g., media content items, live content streams). For example, when simulating a three-second countdown, a first, second, and third light source may initially be illuminated. In this example, the first light source can cease illuminating when one second of time has elapsed, the second light source can cease illuminating when another second of time has elapsed, and the third light source can cease illuminating when yet another second of time has elapsed. This simulated countdown can provide a user (or broadcaster) with a visual indication of when the camera device will begin capturing content (e.g., media content items, live content streams). In some embodiments, the capture feedback module  310  causes one or more light sources associated with the camera device to illuminate based on a pre-defined pattern (or sequence) to visually indicate when the camera device is capturing media content items. For example, one or more of the light sources that emit a particular color may flash. Similarly, the capture feedback module  310  can cause one or more light sources associated with the camera device to illuminate based on a different pre-defined pattern (or sequence) to visually indicate when the camera device is capturing a live content stream. In yet another example, the capture feedback module  310  can cause one or more light sources associated with the camera device to illuminate based on another pre-defined pattern (or sequence) to visually indicate when the camera device is capturing a looping video. Many variations are possible. 
     The illumination feedback module  312  can be configured to illuminate one or more light sources associated with the camera device to visually convey various information (or events). In various embodiments, the illumination feedback module  312  can illuminate the light sources based on instructions provided by a content provider (e.g., social networking system). For example, in some embodiments, the illumination feedback module  312  can receive instructions from the camera feedback module  112  of  FIG. 1 . In various embodiments, the illumination feedback module  312  can be configured to illuminate the light sources differently depending on the information being conveyed. For example, the illumination feedback module  312  can illuminate the light sources based on a pre-defined illumination pattern (or sequence) to convey a first type of user interaction (e.g., like) with content provided by the camera device. Similarly, the illumination feedback module  312  can illuminate the light sources according to a different pre-defined illumination pattern (or sequence) to convey a second type of user interaction (e.g., comment) with content provided by the camera device. 
     In some embodiments, a pre-defined illumination pattern (or sequence) for conveying information may involve flashing or blinking one or more light sources. In some embodiments, a pre-defined illumination pattern (or sequence) for conveying information may involve flashing or blinking one or more light sources that emit one or more particular colors. For example, the camera device may activate light sources that emit the color red to visually confirm a first type of user interaction and light sources that emit the color green to visually confirm a second type of user interaction. In some embodiments, a pre-defined illumination pattern (or sequence) for conveying information may involve flashing or blinking one or more light sources based on some pre-defined order. In various embodiments, a pre-defined illumination pattern (or sequence) for conveying information may involve varying the brightness of one or more light sources, diffusing one or more of the light sources, fading between one or more illuminated light sources, or any combination thereof. 
     In some embodiments, one or more light sources associated with the camera device can be masked to visually represent a shape or icon. For example, a first light source may be masked to visually represent a “like” icon, a second light source may be masked to visually represent a “comment” icon, and a third light source may be masked to visually represent a “heart” icon. In this example, the first light source as masked can be illuminated when a user likes content being provided by the camera device. Similarly, the second light source as masked can be illuminated when a user posts comments in response to the content being provided by the camera device. Further, the third light source as masked can be illuminated when a user selects an option corresponding to a “heart” reaction. Many variations are possible. 
       FIG. 4A  illustrates an example diagram  400 , according to an embodiment of the present disclosure. The example diagram  400  includes a camera device  402  and an individual  404 . In this example, the camera device  402  can implement the camera device module  152  of  FIG. 1 . In some embodiments, the camera device  402  can be instructed to capture a live content stream of the individual  404 . In such embodiments, the live content stream can be broadcasted through a social networking system, as described above. Users can access and interact with the live content stream through the social networking system. In various embodiments, the camera device  402  can include a set of light sources  406  that can be used to visually convey events that occur in response to the live content stream. For example, the light sources  406  can be used to convey (or confirm) various types of user engagement and interactions with the live content stream that occur through the social networking system. 
       FIG. 4B  illustrates an example diagram  420 , according to an embodiment of the present disclosure. The example diagram  400  includes a camera device  422 . In this example, the camera device  422  includes a flash  424 , a lens  426 , and set of light sources  428 . As discussed, these light sources  428  can be illuminated to convey various information. For example, the light sources  428  can be used to convey events that occur in a social networking system in response to content that is captured and provided by the camera device  422 . In the example of  FIG. 4B , a light source  430  is illuminated to visually confirm that a live content stream is being captured and broadcasted by the camera device  422 . Further, a light source  432  is illuminated at a low brightness level to visually indicate a count of likes received for the live content stream from users of the social networking system. Moreover, a light source  434  is illuminated at a medium brightness level to visually indicate an audience size of the live content stream. Many variations are possible. 
       FIG. 4C  illustrates an example diagram  440 , according to an embodiment of the present disclosure. The example diagram  400  includes a camera device  442 . In this example, the camera device  442  includes a flash  444 , a lens  446 , and set of light sources  448 . As discussed, these light sources  448  can be illuminated to convey various information. In this example, some of the light sources  448  are masked to correspond to a particular icon. For example, a light source  450  is masked to represent a “like” icon. Similarly, a light source  452  is masked to represent a “heart” icon. Many variations are possible. 
       FIG. 4D  illustrates an example  460  of an interface  464  for interacting with a broadcaster of a live content stream, according to an embodiment of the present disclosure. In some embodiments, the live content stream may be captured by a camera device in which the camera device module  152  of  FIG. 1  is implemented. The camera device may be installed at a given geographic location. Further, this camera device can be configured to stream the live content through a content provider (e.g., social networking system). In this example, the interface  464  is presented on a display screen of a computing device  462  of a user viewing the live content stream. The interface  464  may be provided through an application (e.g., a web browser, a social networking application, etc.) running on the computing device  462 . In this example, the interface  464  includes a region  466  in which the live content stream being accessed is displayed. The interface  464  also includes a region  468  in which comments posted by various users in response to the live content stream are displayed. The region  468  also includes a field  472  through which the user operating the computing device can input comments to be posted in the region  468 . The region  468  also includes a number of feedback options  470  (e.g., like option, reaction options, etc.) that can be selected to interact with the broadcaster. 
       FIG. 5  illustrates an example process  500 , according to various embodiments of the present disclosure. It should be appreciated that there can be additional, fewer, or alternative steps performed in similar or alternative orders, or in parallel, within the scope of the various embodiments discussed herein unless otherwise stated. 
     At block  502 , a determination is made that content was captured and provided by a camera device. At block  504 , at least one event that occurred in a social networking system in response to the content is determined. At block  506 , one or more instructions can be provided to the camera device for illuminating one or more light sources associated with the camera device. The one or more light sources can be illuminated based at least in part on a pre-defined illumination pattern that visually communicates occurrence of the event. 
     It is contemplated that there can be many other uses, applications, and/or variations associated with the various embodiments of the present disclosure. For example, in some cases, user can choose whether or not to opt-in to utilize the disclosed technology. The disclosed technology can also ensure that various privacy settings and preferences are maintained and can prevent private information from being divulged. In another example, various embodiments of the present disclosure can learn, improve, and/or be refined over time. 
     Social Networking System—Example Implementation 
       FIG. 6  illustrates a network diagram of an example system  600  that can be utilized in various scenarios, in accordance with an embodiment of the present disclosure. The system  600  includes one or more user devices  610 , one or more external systems  620 , a social networking system (or service)  630 , and a network  650 . In an embodiment, the social networking service, provider, and/or system discussed in connection with the embodiments described above may be implemented as the social networking system  630 . For purposes of illustration, the embodiment of the system  600 , shown by  FIG. 6 , includes a single external system  620  and a single user device  610 . However, in other embodiments, the system  600  may include more user devices  610  and/or more external systems  620 . In certain embodiments, the social networking system  630  is operated by a social network provider, whereas the external systems  620  are separate from the social networking system  630  in that they may be operated by different entities. In various embodiments, however, the social networking system  630  and the external systems  620  operate in conjunction to provide social networking services to users (or members) of the social networking system  630 . In this sense, the social networking system  630  provides a platform or backbone, which other systems, such as external systems  620 , may use to provide social networking services and functionalities to users across the Internet. 
     The user device  610  comprises one or more computing devices (or systems) that can receive input from a user and transmit and receive data via the network  650 . In one embodiment, the user device  610  is a conventional computer system executing, for example, a Microsoft Windows compatible operating system (OS), Apple OS X, and/or a Linux distribution. In another embodiment, the user device  610  can be a computing device or a device having computer functionality, such as a smart-phone, a tablet, a personal digital assistant (PDA), a mobile telephone, a laptop computer, a wearable device (e.g., a pair of glasses, a watch, a bracelet, etc.), a camera, an appliance, etc. The user device  610  is configured to communicate via the network  650 . The user device  610  can execute an application, for example, a browser application that allows a user of the user device  610  to interact with the social networking system  630 . In another embodiment, the user device  610  interacts with the social networking system  630  through an application programming interface (API) provided by the native operating system of the user device  610 , such as iOS and ANDROID. The user device  610  is configured to communicate with the external system  620  and the social networking system  630  via the network  650 , which may comprise any combination of local area and/or wide area networks, using wired and/or wireless communication systems. 
     In one embodiment, the network  650  uses standard communications technologies and protocols. Thus, the network  650  can include links using technologies such as Ethernet, 802.11, worldwide interoperability for microwave access (WiMAX), 3G, 4G, CDMA, GSM, LTE, digital subscriber line (DSL), etc. Similarly, the networking protocols used on the network  650  can include multiprotocol label switching (MPLS), transmission control protocol/Internet protocol (TCP/IP), User Datagram Protocol (UDP), hypertext transport protocol (HTTP), simple mail transfer protocol (SMTP), file transfer protocol (FTP), and the like. The data exchanged over the network  650  can be represented using technologies and/or formats including hypertext markup language (HTML) and extensible markup language (XML). In addition, all or some links can be encrypted using conventional encryption technologies such as secure sockets layer (SSL), transport layer security (TLS), and Internet Protocol security (IPsec). 
     In one embodiment, the user device  610  may display content from the external system  620  and/or from the social networking system  630  by processing a markup language document  614  received from the external system  620  and from the social networking system  630  using a browser application  612 . The markup language document  614  identifies content and one or more instructions describing formatting or presentation of the content. By executing the instructions included in the markup language document  614 , the browser application  612  displays the identified content using the format or presentation described by the markup language document  614 . For example, the markup language document  614  includes instructions for generating and displaying a web page having multiple frames that include text and/or image data retrieved from the external system  620  and the social networking system  630 . In various embodiments, the markup language document  614  comprises a data file including extensible markup language (XML) data, extensible hypertext markup language (XHTML) data, or other markup language data. Additionally, the markup language document  614  may include JavaScript Object Notation (JSON) data, JSON with padding (JSONP), and JavaScript data to facilitate data-interchange between the external system  620  and the user device  610 . The browser application  612  on the user device  610  may use a JavaScript compiler to decode the markup language document  614 . 
     The markup language document  614  may also include, or link to, applications or application frameworks such as FLASH™ or Unity™ applications, the Silverlight™ application framework, etc. 
     In one embodiment, the user device  610  also includes one or more cookies  616  including data indicating whether a user of the user device  610  is logged into the social networking system  630 , which may enable modification of the data communicated from the social networking system  630  to the user device  610 . 
     The external system  620  includes one or more web servers that include one or more web pages  622   a ,  622   b , which are communicated to the user device  610  using the network  650 . The external system  620  is separate from the social networking system  630 . For example, the external system  620  is associated with a first domain, while the social networking system  630  is associated with a separate social networking domain. Web pages  622   a ,  622   b , included in the external system  620 , comprise markup language documents  614  identifying content and including instructions specifying formatting or presentation of the identified content. As discussed previously, it should be appreciated that there can be many variations or other possibilities. 
     The social networking system  630  includes one or more computing devices for a social network, including a plurality of users, and providing users of the social network with the ability to communicate and interact with other users of the social network. In some instances, the social network can be represented by a graph, i.e., a data structure including edges and nodes. Other data structures can also be used to represent the social network, including but not limited to databases, objects, classes, meta elements, files, or any other data structure. The social networking system  630  may be administered, managed, or controlled by an operator. The operator of the social networking system  630  may be a human being, an automated application, or a series of applications for managing content, regulating policies, and collecting usage metrics within the social networking system  630 . Any type of operator may be used. 
     Users may join the social networking system  630  and then add connections to any number of other users of the social networking system  630  to whom they desire to be connected. As used herein, the term “friend” refers to any other user of the social networking system  630  to whom a user has formed a connection, association, or relationship via the social networking system  630 . For example, in an embodiment, if users in the social networking system  630  are represented as nodes in the social graph, the term “friend” can refer to an edge formed between and directly connecting two user nodes. 
     Connections may be added explicitly by a user or may be automatically created by the social networking system  630  based on common characteristics of the users (e.g., users who are alumni of the same educational institution). For example, a first user specifically selects a particular other user to be a friend. Connections in the social networking system  630  are usually in both directions, but need not be, so the terms “user” and “friend” depend on the frame of reference. Connections between users of the social networking system  630  are usually bilateral (“two-way”), or “mutual,” but connections may also be unilateral, or “one-way.” For example, if Bob and Joe are both users of the social networking system  630  and connected to each other, Bob and Joe are each other&#39;s connections. If, on the other hand, Bob wishes to connect to Joe to view data communicated to the social networking system  630  by Joe, but Joe does not wish to form a mutual connection, a unilateral connection may be established. The connection between users may be a direct connection; however, some embodiments of the social networking system  630  allow the connection to be indirect via one or more levels of connections or degrees of separation. 
     In addition to establishing and maintaining connections between users and allowing interactions between users, the social networking system  630  provides users with the ability to take actions on various types of items supported by the social networking system  630 . These items may include groups or networks (i.e., social networks of people, entities, and concepts) to which users of the social networking system  630  may belong, events or calendar entries in which a user might be interested, computer-based applications that a user may use via the social networking system  630 , transactions that allow users to buy or sell items via services provided by or through the social networking system  630 , and interactions with advertisements that a user may perform on or off the social networking system  630 . These are just a few examples of the items upon which a user may act on the social networking system  630 , and many others are possible. A user may interact with anything that is capable of being represented in the social networking system  630  or in the external system  620 , separate from the social networking system  630 , or coupled to the social networking system  630  via the network  650 . 
     The social networking system  630  is also capable of linking a variety of entities. For example, the social networking system  630  enables users to interact with each other as well as external systems  620  or other entities through an API, a web service, or other communication channels. The social networking system  630  generates and maintains the “social graph” comprising a plurality of nodes interconnected by a plurality of edges. Each node in the social graph may represent an entity that can act on another node and/or that can be acted on by another node. The social graph may include various types of nodes. Examples of types of nodes include users, non-person entities, content items, web pages, groups, activities, messages, concepts, and any other things that can be represented by an object in the social networking system  630 . An edge between two nodes in the social graph may represent a particular kind of connection, or association, between the two nodes, which may result from node relationships or from an action that was performed by one of the nodes on the other node. In some cases, the edges between nodes can be weighted. The weight of an edge can represent an attribute associated with the edge, such as a strength of the connection or association between nodes. Different types of edges can be provided with different weights. For example, an edge created when one user “likes” another user may be given one weight, while an edge created when a user befriends another user may be given a different weight. 
     As an example, when a first user identifies a second user as a friend, an edge in the social graph is generated connecting a node representing the first user and a second node representing the second user. As various nodes relate or interact with each other, the social networking system  630  modifies edges connecting the various nodes to reflect the relationships and interactions. 
     The social networking system  630  also includes user-generated content, which enhances a user&#39;s interactions with the social networking system  630 . User-generated content may include anything a user can add, upload, send, or “post” to the social networking system  630 . For example, a user communicates posts to the social networking system  630  from a user device  610 . Posts may include data such as status updates or other textual data, location information, images such as photos, videos, links, music or other similar data and/or media. Content may also be added to the social networking system  630  by a third party. Content “items” are represented as objects in the social networking system  630 . In this way, users of the social networking system  630  are encouraged to communicate with each other by posting text and content items of various types of media through various communication channels. Such communication increases the interaction of users with each other and increases the frequency with which users interact with the social networking system  630 . 
     The social networking system  630  includes a web server  632 , an API request server  634 , a user profile store  636 , a connection store  638 , an action logger  640 , an activity log  642 , and an authorization server  644 . In an embodiment of the invention, the social networking system  630  may include additional, fewer, or different components for various applications. Other components, such as network interfaces, security mechanisms, load balancers, failover servers, management and network operations consoles, and the like are not shown so as to not obscure the details of the system. 
     The user profile store  636  maintains information about user accounts, including biographic, demographic, and other types of descriptive information, such as work experience, educational history, hobbies or preferences, location, and the like that has been declared by users or inferred by the social networking system  630 . This information is stored in the user profile store  636  such that each user is uniquely identified. The social networking system  630  also stores data describing one or more connections between different users in the connection store  638 . The connection information may indicate users who have similar or common work experience, group memberships, hobbies, or educational history. Additionally, the social networking system  630  includes user-defined connections between different users, allowing users to specify their relationships with other users. For example, user-defined connections allow users to generate relationships with other users that parallel the users&#39; real-life relationships, such as friends, co-workers, partners, and so forth. Users may select from predefined types of connections, or define their own connection types as needed. Connections with other nodes in the social networking system  630 , such as non-person entities, buckets, cluster centers, images, interests, pages, external systems, concepts, and the like are also stored in the connection store  638 . 
     The social networking system  630  maintains data about objects with which a user may interact. To maintain this data, the user profile store  636  and the connection store  638  store instances of the corresponding type of objects maintained by the social networking system  630 . Each object type has information fields that are suitable for storing information appropriate to the type of object. For example, the user profile store  636  contains data structures with fields suitable for describing a user&#39;s account and information related to a user&#39;s account. When a new object of a particular type is created, the social networking system  630  initializes a new data structure of the corresponding type, assigns a unique object identifier to it, and begins to add data to the object as needed. This might occur, for example, when a user becomes a user of the social networking system  630 , the social networking system  630  generates a new instance of a user profile in the user profile store  636 , assigns a unique identifier to the user account, and begins to populate the fields of the user account with information provided by the user. 
     The connection store  638  includes data structures suitable for describing a user&#39;s connections to other users, connections to external systems  620  or connections to other entities. The connection store  638  may also associate a connection type with a user&#39;s connections, which may be used in conjunction with the user&#39;s privacy setting to regulate access to information about the user. In an embodiment of the invention, the user profile store  636  and the connection store  638  may be implemented as a federated database. 
     Data stored in the connection store  638 , the user profile store  636 , and the activity log  642  enables the social networking system  630  to generate the social graph that uses nodes to identify various objects and edges connecting nodes to identify relationships between different objects. For example, if a first user establishes a connection with a second user in the social networking system  630 , user accounts of the first user and the second user from the user profile store  636  may act as nodes in the social graph. The connection between the first user and the second user stored by the connection store  638  is an edge between the nodes associated with the first user and the second user. Continuing this example, the second user may then send the first user a message within the social networking system  630 . The action of sending the message, which may be stored, is another edge between the two nodes in the social graph representing the first user and the second user. Additionally, the message itself may be identified and included in the social graph as another node connected to the nodes representing the first user and the second user. 
     In another example, a first user may tag a second user in an image that is maintained by the social networking system  630  (or, alternatively, in an image maintained by another system outside of the social networking system  630 ). The image may itself be represented as a node in the social networking system  630 . This tagging action may create edges between the first user and the second user as well as create an edge between each of the users and the image, which is also a node in the social graph. In yet another example, if a user confirms attending an event, the user and the event are nodes obtained from the user profile store  636 , where the attendance of the event is an edge between the nodes that may be retrieved from the activity log  642 . By generating and maintaining the social graph, the social networking system  630  includes data describing many different types of objects and the interactions and connections among those objects, providing a rich source of socially relevant information. 
     The web server  632  links the social networking system  630  to one or more user devices  610  and/or one or more external systems  620  via the network  650 . The web server  632  serves web pages, as well as other web-related content, such as Java, JavaScript, Flash, XML, and so forth. The web server  632  may include a mail server or other messaging functionality for receiving and routing messages between the social networking system  630  and one or more user devices  610 . The messages can be instant messages, queued messages (e.g., email), text and SMS messages, or any other suitable messaging format. 
     The API request server  634  allows one or more external systems  620  and user devices  610  to call access information from the social networking system  630  by calling one or more API functions. The API request server  634  may also allow external systems  620  to send information to the social networking system  630  by calling APIs. The external system  620 , in one embodiment, sends an API request to the social networking system  630  via the network  650 , and the API request server  634  receives the API request. The API request server  634  processes the request by calling an API associated with the API request to generate an appropriate response, which the API request server  634  communicates to the external system  620  via the network  650 . For example, responsive to an API request, the API request server  634  collects data associated with a user, such as the user&#39;s connections that have logged into the external system  620 , and communicates the collected data to the external system  620 . In another embodiment, the user device  610  communicates with the social networking system  630  via APIs in the same manner as external systems  620 . 
     The action logger  640  is capable of receiving communications from the web server  632  about user actions on and/or off the social networking system  630 . The action logger  640  populates the activity log  642  with information about user actions, enabling the social networking system  630  to discover various actions taken by its users within the social networking system  630  and outside of the social networking system  630 . Any action that a particular user takes with respect to another node on the social networking system  630  may be associated with each user&#39;s account, through information maintained in the activity log  642  or in a similar database or other data repository. Examples of actions taken by a user within the social networking system  630  that are identified and stored may include, for example, adding a connection to another user, sending a message to another user, reading a message from another user, viewing content associated with another user, attending an event posted by another user, posting an image, attempting to post an image, or other actions interacting with another user or another object. When a user takes an action within the social networking system  630 , the action is recorded in the activity log  642 . In one embodiment, the social networking system  630  maintains the activity log  642  as a database of entries. When an action is taken within the social networking system  630 , an entry for the action is added to the activity log  642 . The activity log  642  may be referred to as an action log. 
     Additionally, user actions may be associated with concepts and actions that occur within an entity outside of the social networking system  630 , such as an external system  620  that is separate from the social networking system  630 . For example, the action logger  640  may receive data describing a user&#39;s interaction with an external system  620  from the web server  632 . In this example, the external system  620  reports a user&#39;s interaction according to structured actions and objects in the social graph. 
     Other examples of actions where a user interacts with an external system  620  include a user expressing an interest in an external system  620  or another entity, a user posting a comment to the social networking system  630  that discusses an external system  620  or a web page  622   a  within the external system  620 , a user posting to the social networking system  630  a Uniform Resource Locator (URL) or other identifier associated with an external system  620 , a user attending an event associated with an external system  620 , or any other action by a user that is related to an external system  620 . Thus, the activity log  642  may include actions describing interactions between a user of the social networking system  630  and an external system  620  that is separate from the social networking system  630 . 
     The authorization server  644  enforces one or more privacy settings of the users of the social networking system  630 . A privacy setting of a user determines how particular information associated with a user can be shared. The privacy setting comprises the specification of particular information associated with a user and the specification of the entity or entities with whom the information can be shared. Examples of entities with which information can be shared may include other users, applications, external systems  620 , or any entity that can potentially access the information. The information that can be shared by a user comprises user account information, such as profile photos, phone numbers associated with the user, user&#39;s connections, actions taken by the user such as adding a connection, changing user profile information, and the like. 
     The privacy setting specification may be provided at different levels of granularity. For example, the privacy setting may identify specific information to be shared with other users; the privacy setting identifies a work phone number or a specific set of related information, such as, personal information including profile photo, home phone number, and status. Alternatively, the privacy setting may apply to all the information associated with the user. The specification of the set of entities that can access particular information can also be specified at various levels of granularity. Various sets of entities with which information can be shared may include, for example, all friends of the user, all friends of friends, all applications, or all external systems  620 . One embodiment allows the specification of the set of entities to comprise an enumeration of entities. For example, the user may provide a list of external systems  620  that are allowed to access certain information. Another embodiment allows the specification to comprise a set of entities along with exceptions that are not allowed to access the information. For example, a user may allow all external systems  620  to access the user&#39;s work information, but specify a list of external systems  620  that are not allowed to access the work information. Certain embodiments call the list of exceptions that are not allowed to access certain information a “block list”. External systems  620  belonging to a block list specified by a user are blocked from accessing the information specified in the privacy setting. Various combinations of granularity of specification of information, and granularity of specification of entities, with which information is shared are possible. For example, all personal information may be shared with friends whereas all work information may be shared with friends of friends. 
     The authorization server  644  contains logic to determine if certain information associated with a user can be accessed by a user&#39;s friends, external systems  620 , and/or other applications and entities. The external system  620  may need authorization from the authorization server  644  to access the user&#39;s more private and sensitive information, such as the user&#39;s work phone number. Based on the user&#39;s privacy settings, the authorization server  644  determines if another user, the external system  620 , an application, or another entity is allowed to access information associated with the user, including information about actions taken by the user. 
     In some embodiments, the social networking system  630  can include a content provider module  646 . The content provider module  646  can, for example, be implemented as the content provider module  102  of  FIG. 1 . In some embodiments, the user device  610  can include a live stream client module  618 . The live stream client module  618  can be configured to interact with the live stream module  106 , for example, for purposes of streaming live content captured by the user device  610 . The live stream client module  618  can implement any generally known techniques that allow for live streaming of content including, for example, the Real Time Messaging Protocol (RTMP). The user device module  620  can be implemented as the camera device module  152  of  FIG. 1 . In some embodiments, a camera device  670  can be configured to interact with the social networking system  630 . The camera device  670  can include a camera device module  672  and a live stream client module  674 . In some embodiments, the camera device module  672  can be implemented with the camera device module  152 . In some embodiments, the live stream client module  674  can be configured to interact with the live stream module  106 , for example, for purposes of streaming live content captured by the camera device  670 . As discussed previously, it should be appreciated that there can be many variations or other possibilities. 
     Hardware Implementation 
     The foregoing processes and features can be implemented by a wide variety of machine and computer system architectures and in a wide variety of network and computing environments.  FIG. 7  illustrates an example of a computer system  700  that may be used to implement one or more of the embodiments described herein in accordance with an embodiment of the invention. The computer system  700  includes sets of instructions for causing the computer system  700  to perform the processes and features discussed herein. The computer system  700  may be connected (e.g., networked) to other machines. In a networked deployment, the computer system  700  may operate in the capacity of a server machine or a client machine in a client-server network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. In an embodiment of the invention, the computer system  700  may be the social networking system  630 , the user device  610 , and the external system  720 , or a component thereof. In an embodiment of the invention, the computer system  700  may be one server among many that constitutes all or part of the social networking system  630 . 
     The computer system  700  includes a processor  702 , a cache  704 , and one or more executable modules and drivers, stored on a computer-readable medium, directed to the processes and features described herein. Additionally, the computer system  700  includes a high performance input/output (I/O) bus  706  and a standard I/O bus  708 . A host bridge  710  couples processor  702  to high performance I/O bus  706 , whereas I/O bus bridge  712  couples the two buses  706  and  708  to each other. A system memory  714  and one or more network interfaces  716  couple to high performance I/O bus  706 . The computer system  700  may further include video memory and a display device coupled to the video memory (not shown). Mass storage  718  and I/O ports  720  couple to the standard I/O bus  708 . The computer system  700  may optionally include a keyboard and pointing device, a display device, or other input/output devices (not shown) coupled to the standard I/O bus  708 . Collectively, these elements are intended to represent a broad category of computer hardware systems, including but not limited to computer systems based on the x86-compatible processors manufactured by Intel Corporation of Santa Clara, Calif., and the x86-compatible processors manufactured by Advanced Micro Devices (AMD), Inc., of Sunnyvale, Calif., as well as any other suitable processor. 
     An operating system manages and controls the operation of the computer system  700 , including the input and output of data to and from software applications (not shown). The operating system provides an interface between the software applications being executed on the system and the hardware components of the system. Any suitable operating system may be used, such as the LINUX Operating System, the Apple Macintosh Operating System, available from Apple Computer Inc. of Cupertino, Calif., UNIX operating systems, Microsoft® Windows® operating systems, BSD operating systems, and the like. Other implementations are possible. 
     The elements of the computer system  700  are described in greater detail below. In particular, the network interface  716  provides communication between the computer system  700  and any of a wide range of networks, such as an Ethernet (e.g., IEEE 802.3) network, a backplane, etc. The mass storage  718  provides permanent storage for the data and programming instructions to perform the above-described processes and features implemented by the respective computing systems identified above, whereas the system memory  714  (e.g., DRAM) provides temporary storage for the data and programming instructions when executed by the processor  702 . The I/O ports  720  may be one or more serial and/or parallel communication ports that provide communication between additional peripheral devices, which may be coupled to the computer system  700 . 
     The computer system  700  may include a variety of system architectures, and various components of the computer system  700  may be rearranged. For example, the cache  704  may be on-chip with processor  702 . Alternatively, the cache  704  and the processor  702  may be packed together as a “processor module”, with processor  702  being referred to as the “processor core”. Furthermore, certain embodiments of the invention may neither require nor include all of the above components. For example, peripheral devices coupled to the standard I/O bus  708  may couple to the high performance I/O bus  706 . In addition, in some embodiments, only a single bus may exist, with the components of the computer system  700  being coupled to the single bus. Moreover, the computer system  700  may include additional components, such as additional processors, storage devices, or memories. 
     In general, the processes and features described herein may be implemented as part of an operating system or a specific application, component, program, object, module, or series of instructions referred to as “programs”. For example, one or more programs may be used to execute specific processes described herein. The programs typically comprise one or more instructions in various memory and storage devices in the computer system  700  that, when read and executed by one or more processors, cause the computer system  700  to perform operations to execute the processes and features described herein. The processes and features described herein may be implemented in software, firmware, hardware (e.g., an application specific integrated circuit), or any combination thereof. 
     In one implementation, the processes and features described herein are implemented as a series of executable modules run by the computer system  700 , individually or collectively in a distributed computing environment. The foregoing modules may be realized by hardware, executable modules stored on a computer-readable medium (or machine-readable medium), or a combination of both. For example, the modules may comprise a plurality or series of instructions to be executed by a processor in a hardware system, such as the processor  702 . Initially, the series of instructions may be stored on a storage device, such as the mass storage  718 . However, the series of instructions can be stored on any suitable computer readable storage medium. Furthermore, the series of instructions need not be stored locally, and could be received from a remote storage device, such as a server on a network, via the network interface  716 . The instructions are copied from the storage device, such as the mass storage  718 , into the system memory  714  and then accessed and executed by the processor  702 . In various implementations, a module or modules can be executed by a processor or multiple processors in one or multiple locations, such as multiple servers in a parallel processing environment. 
     Examples of computer-readable media include, but are not limited to, recordable type media such as volatile and non-volatile memory devices; solid state memories; floppy and other removable disks; hard disk drives; magnetic media; optical disks (e.g., Compact Disk Read-Only Memory (CD ROMS), Digital Versatile Disks (DVDs)); other similar non-transitory (or transitory), tangible (or non-tangible) storage medium; or any type of medium suitable for storing, encoding, or carrying a series of instructions for execution by the computer system  700  to perform any one or more of the processes and features described herein. 
     For purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the description. It will be apparent, however, to one skilled in the art that embodiments of the disclosure can be practiced without these specific details. In some instances, modules, structures, processes, features, and devices are shown in block diagram form in order to avoid obscuring the description. In other instances, functional block diagrams and flow diagrams are shown to represent data and logic flows. The components of block diagrams and flow diagrams (e.g., modules, blocks, structures, devices, features, etc.) may be variously combined, separated, removed, reordered, and replaced in a manner other than as expressly described and depicted herein.
