Systems, methods, and non-transitory computer-readable media can obtain a plurality of content items that are available to be presented in a content feed of a first user, wherein each content item has a corresponding lifespan that indicates when the content item expires and is no longer available for presentation. A content feed having at least a first content item from the plurality of content items can be provided to a computing device of the first user. A determination can be made that at least one second user has provided feedback for the first content item, the feedback indicating an up-vote or a down-vote of the first content item. The lifespan of the first content item can be adjusted based at least in part on the feedback.

Systems and methods for content presentation

A user device requests a web page from a web server of a third-party website, which is separate from a social networking system. The web server from the third-party website sends a markup language document for the requested web page to the user device which includes an instruction for a browser application running on the user device to incorporate information obtained from the social networking system within the web page. Based on the instruction in the received markup language document, the user device requests personalized content from the social networking system, which generates the requested personalized content based on social information about the user. The user device then renders the web page with the personalized content contained in a frame and displays the rendered web page and the frame to the user.

Personalizing a web page outside of a social networking system with content from the social networking system

In one embodiment, a computing device receives an indication of a first user action by a first user. The computing device determines a topic of the first user action based on analyzing content associated with the first user action, and determines whether the first user has a preference to exclude posts associated with the topic or a category associated with the topic. If the first user has not indicated any preference to exclude posts associated with the topic or the category, then the computing device identifies a second user action by a second user and related to the topic, and determines whether the first user has indicated a preference to exclude posts associated with the second user. If the first user has not indicated any preference to exclude posts associated with the second user, the first user is provided with access to the second user action.

Facilitating interaction among users of a social network

In one embodiment, a method includes determining rankings for a plurality of objects of a social-networking system, where the social-networking system includes a social graph that includes a plurality of nodes and a plurality of edges connecting the nodes. Each object corresponds to a node of the social graph, and each ranking for each object is determined based on a number of edges being connected to the node to which the respective object corresponds. The objects are stored in a plurality of partitions of a database, where each partition stores only objects having a particular ranking. The objects are indexed in the partitions by a plurality of search indices that each index only a particular one of the plurality of partitions.

Indexing edge-ranked based partitions

A method and system for static resource caching in a networking system are provided. The system includes a fetcher instantiated on a particular user device. The fetcher can be a browser plug-in, a separate process or a program integrated into another process on the particular user device. The fetcher downloads static resource data from a web server and groups the downloaded static resource data into a plurality of static resource packages. In some embodiments, the fetcher may predict new static resource package(s) that the particular user may need by analyzing the particular user's activities on the web server and web traffics on the particular user device. Therefore, static resource data from the web server may be effectively cached on the particular user device even before any browser is launched on the particular user device.

Static resource caching

Indexing and retrieving real time content in a social networking system is disclosed. A user-term index includes user-term partitions, each user-term partition comprising temporal databases. As a post is received from a user, a user identifier, a post identifier, and a post is extracted. An object store communicatively coupled to a temporal database for recently received content is queried to determine whether terms in the post has already been stored. A term identifier is stored in the user-term index with the user and post identifiers. A forward index stores the post by post identifier. Responsive to a search query, the user-term index is searched by the user's connections and the terms. A real time search engine compiles the results of the user-term index query and retrieves the stored posts from the forward index. The search results may then be ranked and cached before presentation to the searching user.

Real time content searching in social network

In one embodiment, a computing device receives an indication of a first user action by a first user. The computing device determines a topic of the first user action based on analyzing content associated with the first user action, and determines whether the first user has a preference to exclude posts associated with the topic or a category associated with the topic. If the first user has not indicated any preference to exclude posts associated with the topic or the category, then the computing device identifies a second user action by a second user and related to the topic, and determines whether the first user has indicated a preference to exclude posts associated with the second user. If the first user has not indicated any preference to exclude posts associated with the second user, a reference associated with the second user action is sent to the first user.

In one embodiment, a method includes receiving a first user action relating to a first topic from a first user, identifying the first topic based on the first user action, identifying one or more second posts that relate to the first topic, and transmitting to the first user one or more of the second posts or information associated with the second posts in a structured document for display to the first user, the structured document further comprising one or more interactive elements that enable the first user to interact with the one or more second posts or to respective second users that declared the second posts.

In one embodiment, a method includes maintaining data stores for objects of a social-networking system, each data store being configured to store objects of a particular one of multiple object types indexed by a search index; receiving an object; identifying an object type of the received object; storing the received object in at least one data store being configured to store objects of the identified object type; and updating the search index of the at least one data store based on the received object.
