Abstract: A database management system maintains a collection of data using a log-based storage structure. In response to a request to store data items (key-value pairs), the database management system stores mapping information to a data item in an in-memory data structure while the data items are stored on the log-based storage structure. The hash of the key includes information to identify an index entry that comprises information that maps to the location of the data item stored on the log-based storage structure.

Abstract: Techniques for using ferroelectric liquid crystals Dammann grating (FLCDG) for light detection and ranging devices are disclosed. In LiDAR devices, accuracy, response time, and cost performance can be limited by some factors, such as laser pulse width, time resolution of a time-to-digital conversion chip, detector bandwidth, shot noise, and time error generated by electronic circuits. A FLCDG-based architecture can improve a LiDAR device, and provide for one-shot capturing due to the high switching speed at very low driving voltage provided by ferroelectric liquid crystals and the equal diffracting ability of Dammann grating.

Abstract: Some implementations include methods for replacing advertisements that have been inserted into a manifest associated with live streaming and may include receiving a request for a manifest from a player to enable a user to watch a live stream of an event. The request may be received at a first time when the live stream is already in progress. The manifest may be generated to include content fragments associated with the live event and advertisements based on first set of selection criteria. The manifest may be sent to the player to enable the user to watch the live stream. A seek back request may be received from the player to enable the user to watch the live stream at a second time earlier than the first time. The manifest may be updated to replace at least one advertisement with a replacement advertisement selected based on second set of selection criteria.

Abstract: A system for utilizing media content reference point information to perform media content encoding, and supplemental content stitching and/or insertion. Media content can be encoded and packaged based on boundaries of the media content. The boundaries can be received from a third-party and/or generated via an automated process. Target boundaries can be selected based on accuracy levels associated with the received and/or generated boundaries. Supplemental content can be stitched and/or inserted into packaged media content based on audio and video content of the packaged media content being aligned.

Abstract: The present concepts may automate and optimize deployment to a cloud computing fleet. Artificial intelligence and/or optimization algorithms may be used to find optimal deployment parameters (e.g., deployment order of computers in the fleet) that minimize deployment time and minimize deployment risk. For example, machine-learning prediction models may be used to generate a shortest path graph problem models a deployment planning problem. Then, optimization algorithms may be used to efficiently find approximations of Pareto-optimal solutions to the shortest path graph problem. Depending on the preferred level of time and risk, one of the solutions may be used to run the deployment.

In one aspect, the first device extends the service period beyond the determined duration, in response to receiving a first indicator of the one or more indicators. In one aspect, the first device communicates with the second device the additional data during the service period extended beyond the determined duration.

Abstract: In an approach for augmenting contextual timeline markers on a virtual video conversation, a processor records a virtual meeting on a virtual meeting platform with one or more participants. Responsive to the virtual meeting chair ending the virtual meeting with one or more incomplete tasks, a processor creates an augmented recording of the virtual meeting, wherein the augmented recording includes a timeline composed of a plurality of timeline markers, wherein a timeline marker is associated with a conversation that occurs at a particular contextual conversation point during the virtual meeting.
