A video optimizer receives a request to optimize a source file and stream the optimized file. The request may be accompanied by a key uniquely identifying the original source file to be optimized and an optimized version of the source file to stream to the client. The key uniquely identifies the source video file as it exists on an origin server to prevent transmission of modified source video and the optimized version of the source file by optimization parameters to ensure compatibility with the user device. The video optimizer queries a cache database in response to the received request, which contains references keys and locations of optimized source files among local caches in a cluster of video optimizers. The cache database responds indicates whether a matching optimized version of the source file exists in a local cache of a given video optimizer in the cluster.

Database systems and methods that implement a data aggregation framework are provided. The framework can be configured to optimize aggregate operations over non-relational distributed databases, including, for example, data access, data retrieval, data writes, indexing, etc. Various embodiments are configured to aggregate multiple operations and/or commands, where the results (e.g., database documents and computations) captured from the distributed database are transformed as they pass through an aggregation operation. The aggregation operation can be defined as a pipeline which enables the results from a first operation to be redirected into the input of a subsequent operation, which output can be redirected into further subsequent operations. Computations may also be executed at each stage of the pipeline, where each result at each stage can be evaluated by the computation to return a result. Execution of the pipeline can be optimized based on data dependencies and re-ordering of the pipeline operations.

A computerized method, system for, and computer-readable medium operable to: retrieve program details data about at least one media program. Retrieve social media posts involving the at least one media program. Match the retrieved program details data with the retrieved social media posts to find matching locations. Store time offset data corresponding to the matched locations within the at least one media program into at least one micropost. Rank the at least one media program by the number of microposts corresponding to the at least one media program. Present the at least one media program, each of the at least one media program with at least one micropost, wherein the at least one micropost comprises a link to the original social media page hosting the social media post and a video deeplink that plays a time off-set video, the time off-set video starting from the stored time offset data.

Embodiments are directed are towards the transparent summarization of events. Queries directed towards summarizing and reporting on event records may be received at a search head. Search heads may be associated with one more indexers containing event records. The search head may forward the query to the indexers the can resolve the query for concurrent execution. If a query is a collection query, indexers may generate summarization information based on event records located on the indexers. Event record fields included in the summarization information may be determined based on terms included in the collection query. If a query is a stats query, each indexer may generate a partial result set from previously generated summarization information, returning the partial result sets to the search head. Collection queries may be saved and scheduled to run and periodically update the summarization information.

A personalized feed system is described herein that provides feeds that are tailored to the preferences of each user of a real estate website or application. A user signs up to receive a stored profile with the website, and the profile includes information such as what geographical regions the buyer is interested in, what types of homes the buyer is looking for, and so on. The personalized feed system uses this information to provide a feed specific to the buyer that notifies the buyer of listings that are of particular relevance to that buyer. The personalized feed system summarizes other real estate events that are relevant to the user in a single time-oriented feed. Buyers receive information about new and/or modified listings, sales, outstanding offers, status of a transaction, and the like, while sellers receive information about sales, new and/or modified listings, open offers, and so on.

An approach for managing memory usage in cloud and traditional environments using usage analytics is disclosed. The approach may be implemented in a computer infrastructure including a combination of hardware and software. The approach includes determining that space is available within one or more tables which have schema definitions with string fields having a predefined length. The approach further includes creating a virtual table and mapping the available space to the virtual table for population by one or more records.

A method and apparatus for reserving a usable storage space on a storage device is provided. The method includes collecting context data representing an environment surrounding the storage device; selecting at least one file from among files stored in the storage device by using at least one of the context data and user profile data; and processing the selected file and reserving a usable storage space on the storage device. The method reserves the usable storage space by using the context data or user profile data, thereby allowing efficient reserving of usable storage space without a user's manual intervention and preventing waste of unnecessary resources.

An information processing unit includes: a diagnostic image input section that inputs the diagnostic image; an operation information obtaining section that obtains display operation history information representing an operation history of a user who controls displaying of the diagnostic image; a query image generation section that extracts a predetermined region of the input diagnostic image to generate a query image; a diagnosed image obtaining section that supplies the generated query image and the display operation history information to a diagnosed image search unit and obtains the diagnosed image obtained as a search result by the diagnosed image search unit; and a display control section that displays the diagnostic image and the obtained diagnosed image for comparison.

A method of incrementally replicating investigative analysis data is disclosed along with a system for performing the same. The method and system provide the ability to break a data replication job into multiple “replication chunks” which can be exported and imported separately. By doing so, the method and system can efficiently replicate large numbers of data object changes over an unreliable data network.

A method of forming a vertical transistor includes forming a fin structure on a substrate, forming a gate structure on the fin structure, and forming a bottom source/drain (S/D) region on the fin structure, such that an air gap is formed between the bottom S/D region and the gate structure.
