Abstract: A question-and-answer application that displays topic-specific biographical information about users when presenting certain content elements is described. The topic-specific biographical information for a user may be displayed in various contexts, such as with an answer to a question on a question page for the question, or with information identifying a user who is following a question or a topic. With some embodiments, a user's topic-specific biographical information may be provided by the user, provided or suggested by another user, or obtained from an external data source.

Abstract: A question-and-answer application with an “ask-to-answer” feature is described. The ask-to-answer feature enables any user to solicit an answer to a question from another user. Upon soliciting another user for an answer to a particular question, a message with a call to action is directed to the solicited user. The message may include a copy of the text of the question and may provide a mechanism (e.g., a selectable user interface element) enabling the solicited user to pass on answering the question. Subsequent to the solicitation, the question page for the question will include a notification with information about the solicitation, including in some instances information identifying the user who has been asked to answer the question and the number of times the user has been asked to provide an answer to the question.

Abstract: A method for loading multiple versions of the same native library in a native runtime environment. In one embodiment, the method comprises cloning a native library workspace with a first version number as a cloned native library; applying a namespace across the cloned native library; injecting a macro into source code associated with the cloned native library; adding a dependency to the cloned native library in source code associated with the native runtime environment; and registering the first version number in a project configuration of the native runtime environment.

Abstract: Systems and methods for application development via a graphical user interface (GUI) using an Entity-Component-System (ECS) architecture are provided herein. In some embodiments, a method for application development may include receiving a selection of at least one actor to be part of a game scene; displaying a representation of the at least one actor in the game scene; receiving a selection of one or more behaviors to associate with each of the at least one actors in the game scene; storing the selected one or more behaviors as associations with each of the at least one actors, wherein the associations are stored in a hash table; updating, each of that at least one actors and their associated behaviors; and automatically creating an executable video game based on the at least one actor and associated behaviors in an ECS architecture without the need for user written software code.

Abstract: A method for modifying a native runtime environment comprising modifying symbols in the least one of a compiled executable or byte-code of each of a plurality of library versions, modifying references to the symbols in development code associated with the at least one of the compiled executable or byte-code, building the development code into a plurality of versioned library packages, renaming identifiers in each of the versioned library packages and modify an application build for the native runtime environment to reference each of the versioned library packages according to their renamed identifiers.

Abstract: An external system (such as a website) that interacts with users communicates with a social networking system to access information about the users, who may also be users of the social networking system. If a privacy setting is changed in the social networking system, and the change applies to information that has been shared with an external system, the change is enforced at the external system. For example, the external system may be notified that the information is invalid and must be deleted, or the external system may periodically request the information so that changes to the privacy settings are eventually experienced at the external systems. When an external system again needs the information, whether expired naturally or actively invalidated by the social network, the external system sends a new request for the information, which is subject to the (possibly revised) privacy settings.

Abstract: A question-and-answer application having questions with which topics are associated is described. In some embodiments, user-generated topics are assigned to questions to indicate the subject matter covered by the questions. The application logic includes topic merge logic for quickly and efficiently merging two topics, while enabling the topic merge operation to be easily undone if necessary.

Abstract: A social networking system contains information describing users of the social network and various connections among the users. A user can access multiple external systems that communicate with the social networking system to access information about the users of the social networking system. Login status of the user account on the social networking system is maintained. If the login status of the user account on the social networking system indicates that the user is not logged in, the user is required to provide authentication information. If the login status of the user account indicates that the user is logged in, social network information is provided to the user via an external system, subject to the privacy settings of users of the social networking system. If the user logs out from an external system, the user is also logged out from the social networking system.
