Abstract: A planar lightwave circuit (PLC) assembly is used for a transceiver module that includes a circuit board having photodetectors mounted at a spacing from one another. A transmitter mounted on the circuit board is configured to transmit optical signals for a network. The PLC assembly includes at least one PLC chip and at least one fiber array. The PCL chip mounts on the transmitter and is configured to receive optical signals for the network. The fiber array has optical fibers connecting between the PLC chip and the photodetectors. The array's first end connected to the PLC chip has a first pitch between the optical fibers, while the array's second end has at least one connector connected adjacent the photodetectors and having a second fiber pitch, which is greater than the first pitch and is configured to the spacing of the photodetectors.

Abstract: Exemplary embodiments relate to techniques for representing conversations in a messaging system, where content serves as the organizing feature or primitive of a messaging inbox. In the messaging inbox, content may be aggregated in two hierarchical tiers: first, on a per-sender basis, and second on a per-content basis. Conversational threads may be stored in buckets represented by a relationship tuple (sender, receiver). Individual content threads may be represented by a thread identifier of the structure (content ID, sender, receiver). One piece of content may be associated with multiple conversations through the thread ID. Replies may be organized in a hierarchy under the thread ID tuple. Content ephemerality may be implemented by tying the content identifier to ephemerality conditions. Different users may view the content at different times, since the thread ID tuple can be removed from a sender bucket without removing the associated content.

Abstract: Techniques are described that enable a user to edit and customize captions generated by a social networking system, such as transcriptions of an audio clip. In some cases, a social networking system receives, from a first user account, a video and an audio clip associated with the video, and determines that the audio clip contains speech. The social networking system may leverage a speech-to-text component to generate a first text caption based at least in part on the speech in the audio clip. The social networking system provides the first text caption to the first user account, and receives a user input to modify a word included in the first text caption. The social networking system generates a second text caption based at least in part on the user input, and provides the video, including the second text caption, to a second user account.

Abstract: Exemplary embodiments relate to techniques for representing conversations in a messaging system, where content serves as the organizing feature or primitive of a messaging inbox. In the messaging inbox, a first level of organization allows for the selection of a user account associated with shared content. Upon selecting the user account, the account's content (e.g., photographs, videos, etc.) appear as a second level of organization. Thus, content may be aggregated in two hierarchical tiers: first, on a per-sender basis, and second on a per-content basis. In some embodiments, messages generated in response to the content may be displayed on the content. The content may be made progressively darker as more replies are received. Messages can be made temporary using a number of different ephemerality models. Messages may also be made permanent, with previously shared content shown in respective inbox drawers.

Abstract: Systems and techniques are described that enable users to interact and share content through a social network application and/or service with other users. A social networking system may receive status information (e.g., a heartbeat) associated with a first account, where the status information includes first location information and/or first activity information associated with the first account, and may determine a status signal based at least in part on a context associated with the first account and the status information. The social networking system may determine a status associated with the first account, where the status includes second location information and/or second activity information associated with the user device which is less specific than the first location information and first activity information. The social network system may send the status to a second account.

Abstract: One or more embodiments of the disclosure provide systems and methods for providing content presentations to users of a content presentation system. A content presentation generally includes a plurality of content items provided by one or more users of the content presentation system. In one or more embodiments, the content presentation system may enable a user to modify multiple content attributes using a simple gesture. In another embodiment, the content presentation system can provide dynamic and interactive notifications to the user corresponding to content items and/or other co-users.

Abstract: A social networking system provides a user with a newsfeed that includes content selected by the social networking system for presentation to the user and allows the user to request a user-specific profile feed associated with an additional user connected to the user on the social networking system. The user-specific profile feed includes content received from the additional user and designated by the additional user as eligible for presentation in a user-specific profile feed associated with the additional user. If the user requests to view the user-specific profile feed, the social networking system generates and presents the user with the user-specific profile feed including the designated content and information identifying the additional user from whom the content was received. The social networking system stores a visitation state identifying the user presented with the user-specific profile feed and provides information describing the visitation state to the additional user.

Abstract: Systems, methods, and non-transitory computer-readable media can determine a geographical area associated with a crisis. A first user within the geographical area can be identified based on locational data associated with the first user. Information about a safety status of the first user can be actively requested or acquired from the first user. The safety status of the first user can be broadcasted, communicated, or provided to at least a second user associated with the first user.

Abstract: Systems, methods, and non-transitory computer-readable media can receive event information for an event. A determination can be made that a first user is attending the event. The first user can be provided with access to an event-related content user interface based on the determining that the first user is attending the event. The first user can use the event-related content item user interface to create and submit one or more event-related content items for potential inclusion in an event story associated with the event.
