Abstract: Techniques for extracting and ranking multiple topic descriptions based on source contexts and subsequently selecting individual topic descriptions to surface based on recipient contexts. More specifically, a mining platform may extract, from a set of source documents making up a corpus, topic descriptions for various topics that are relevant to an enterprise. The mining platform may further rank the extracted topic descriptions based on a source context of those documents from which individual topic descriptions are extracted. Subsequently, when users access enterprise documents including term-usage instances of topics for which one or more topic descriptions have been extracted and ranked, a description serving module may select a topic description that is contextually appropriate for a recipient view the enterprise documents.

Abstract: Examples provide an input device for an adaptive chord typing system. An input device includes a plurality of keys and a chord manager in firmware or software on the device. The chord manager analyzes input words and identifies frequently input candidate words. The chord manager automatically generates recommended chords that are shorter than the identified candidate words to serve as a shortcut during typing.

If the user accepts a recommended chord, the chord is mapped to a corresponding frequently input word. When the user types a mapped chord using the keys on the input device, the input device generates keystroke data corresponding to the corresponding frequently input word(s), as if the user had actually input the word(s) rather than the chord to increase typing speed.

Abstract: A capacitive touch-sensor system comprises an electrode array coupled to an electromagnetic-noise source, a hardware interface, and associated output logic. The electrode array acquires sensory signal. The hardware interface exposes a touch-position output of the capacitive touch sensor. The output logic determines that an anomalous sensory electrode of the electrode array is proximate to a touchpoint, the anomalous sensory electrode providing an anomalous response to noise from the electromagnetic-noise source. Pursuant to determining that the anomalous sensory electrode is proximate to the touchpoint, the output logic identifies a non-anomalous sensory electrode of the electrode array which is usable to detect the noise. If an amplitude of the sensory signal from the non-anomalous sensory electrode exceeds a predetermined threshold, then the output logic invalidates the sensory signal for touchpoint resolution.

Abstract: An application programming interface (API) proxy intercepts API calls and responses for an application under test in a development environment, simulating (e.g., mocking) rate limiting and throttling behavior, which is otherwise challenging to test. The API proxy receives a API call and, based on a resource limiting parameter (e.g., rate-limiting or otherwise throttling), determines that the API call should be forwarded to the API endpoint. When the API proxy receives another API call from the application, destined for the same API endpoint, the API proxy determines to not forward the second API call, based on the resource limiting parameter (e.g., too soon after the first API call, or requests too much of a computational burden, such as exceeding a resource quota). The API proxy instead returns a throttling response, as would be expected from the API endpoint. The API proxy provides guidance messages for both outgoing calls and incoming responses.

Abstract: Cache-based tracing based on categorizing memory regions as being logged or not logged. A computer system identifies a first memory region within a first memory space of a first context, and determines that the first context is in a logging state. The computer system configures a data structure to categorize the first memory region as being logged. The data structure also categorizes a second memory region corresponding to a second context as being not logged. The computer system exposes the data structure to a processor. Upon detecting a memory access by a processing unit, the processor uses determinations of one or more of (i) whether a target memory address is categorized as being logged or not logged, (ii) whether an executing context is logging or not non-logging, or (iii) a type of the memory access to initiate a logging action or refrain from the logging action.

The service determines the transfer number and provides it to the first system. The first system performs the call transfer using the number. After the transfer is complete, the second system provides a request for the context, and the service provides the context to the second system.

Abstract: The technology described herein builds an optimal refresh schedule by minimizing a cost function constrained by an available refresh bandwidth. The cost function receives an importance score for a content item and a change rate for the content item as input in order to optimize the schedule. The cost function is considered optimized when a refresh schedule is found that minimizes the cost while using the available bandwidth and no more. The technology can build an optimized schedule to refresh content with incomplete change data, content with complete change data, or a mixture of content with and without complete change data. It can also re-learn content item change rates from its own schedule execution history and re-compute the refresh schedule, ensuring that this schedule takes into account the latest trends in content item updates.

Abstract: Initially, a database schema is parsed and a table tree structure is created delineating the relationships between data that are identified in the schema. In addition to accomodating relationships between main tables of data, the table tree structure also accomodates possible side tables of data, and possible circular references between tables, should such be encountered when parsing the schema. Subsequently, a migration mechanism consumes the generated table tree structure and iteratively migrates data in accordance therewith. Individual layers of the table tree structure are migrated consecutively with referenced layers being migrated prior to referencing layers. Circular links are accommodated through temporary null values, and side tables are accommodated during migration of the referencing main table. The iterative process provides completeness and fault tolerance/failure recovery.

Abstract: Timekeeping on a computing device is deterministically performed by implementing two successive calls to a time function that returns current time based on a continuously running counter that is maintained in one or more cores of the device's CPU. The same fixed time computation parameters are used in each call, with the single variable being a value that is read from the counter. For the initial call to the time function, the processor optimizes the instruction execution by predicting the function's execution path based on observed patterns. As the instructions and data are already cached, and the processor has the results of the prior execution path prediction, the subsequent call executes quickly and predictably relative to the initial call while the processor remains in a working (i.e., non-sleep) state. The series of calls provides a deterministic time computation with improved accuracy by mitigating the unpredictability of processor sleep state delays.
