Abstract: Techniques of memory tiering in computing devices are disclosed herein. One example technique includes retrieving, from a first tier in a first memory, data from a data portion and metadata from a metadata portion of the first tier upon receiving a request to read data corresponding to a system memory section. The method can then include analyzing the data location information to determine whether the first tier currently contains data corresponding to the system memory section in the received request. In response to determining that the first tier currently contains data corresponding to the system memory section in the received request, transmitting the retrieved data from the data portion of the first memory to the processor in response to the received request. Otherwise, the method can include identifying a memory location in the first or second memory that contains data corresponding to the system memory section and retrieving the data from the identified memory location.

Abstract: In order to reduce the number of instructions that the compiler generates to load the address of a global variable into a register, the compiler uses a technique that analyzes the global variables used in each function in order to estimate which global variables will be located within the same memory page and have a common base address. A base global variable is selected for each function whose address is fully resolved. The address of each subsequent global variable is constructed using an offset relative to the address of the base global variable that is based on the subsequent global variable's position in a global variable order list.

Abstract: Techniques and tools for reducing latency in video encoding and decoding by constraining latency due to reordering of video frames, and by indicating the constraint on frame reordering latency with one or more syntax elements that accompany encoded data for the video frames. For example, a real-time communication tool with a video encoder sets a syntax element that indicates a constraint on frame reordering latency, which is consistent with inter-frame dependencies between multiple frames of a video sequence, then outputs the syntax element. A corresponding real-time communication tool with a video decoder receives the syntax element that indicates the constraint on frame reordering latency, determines the constraint on frame reordering latency based on the syntax element, and uses the constraint on frame reordering latency to determine when a reconstructed frame is ready for output (in terms of output order).

Abstract: Executing a user selected portion of an executable graph, the method includes, for an executable graph, the executable graph comprising executable modules, identifying a user selected sub-portion of the executable graph. The method further includes determining that data is needed from upstream modules in the graph to execute the sub-portion of the executable graph. The method further includes obtaining the needed data. The method further includes executing the user selected sub-portion of the graph in isolation from other portions of the executable graph. This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

Abstract: Conventional laptop computers may utilize a door-hinge style or bezel-behind-base style hinge to connect a display with a keyboard of the laptop computer. Typically, these hinges present an undesirable discontinuous visual impression to the user. In the disclosed technology, a leading edge of a display abuts a leading edge of a keyboard. The disclosed sliding double-pivot hinge places a pivot axis parallel and coincident with the abutting interface, the leading edges of the display and the keyboard remain abutting throughout a rotational range of motion of the display with reference to the keyboard. The resulting visual impression to the user is that the display is contiguous with the keyboard regardless of the display angle. Further, the disclosed sliding double-pivot hinge may be used in a kickstand to permit the kickstand to rotate up to 180 degrees to fold back on itself and lay flat against an associated computing device.

Abstract: Procedural optimization is facilitated by receiving user input for creating or modifying a body of text comprising a procedure, detecting one or more procedural steps associated with the procedure using a procedural step detection module, automatically searching within a corpus of references for one or more related procedural steps using a related procedural step extraction module, automatically identifying one or more outcomes within the corpus of references associated with the one or more related procedural steps using an outcome extraction module, automatically determining whether the one or more outcomes comprise detrimental results using an outcome analysis module, and, in response to determining a set of detrimental outcomes from the one or more outcomes that comprise detrimental results, presenting a detriment indicator within the user interface in association with the one or more procedural steps.

Abstract: Versions of an application are managed by receiving a request for a version of an application, retrieving, responsive to the received request, a version of a master application component based at least in part on version data that associates a version of the master application component with the version of the application, retrieving a relationship operable to relate the version of the master application component with a corresponding version of a first component on which the master application component depends for a function of the application, retrieving the corresponding version of the first component, responsive to the retrieving of the relationship, assembling the version of the application based at least in part on the retrieved version of the master component, the retrieved relationship, and the retrieved first component, and providing for an execution of the assembled version of the application.

Abstract: The present disclosure relates to generating a search graph or search index to aid in receiving a search query and identifying results of a dataset based on the search query. For example, systems disclosed herein may generate a navigable search graph including vertices representative of objects or points within a dataset that enables a computing device having access to the search graph to navigate vertices of the graph along an identified path until arriving at a point within the search graph that corresponds to a value associated with the search query. Upon identifying a location within the graph corresponding to the search query, systems disclosed herein may identify a neighborhood of points (e.g., vertices) corresponding to items from the dataset and output a set of results for the search query representative of determined results for the search query.

Abstract: Technologies are described for categorization of time blocks in calendars. A time block to be categorized on a user's calendar may be determined based on a direct user input or inference from user history or behavior. Next, a category to be assigned, a beginning, and an end for the time block may be determined. The time block may be the same on all work days, different on each day, etc. One or more exceptions to be processed during the categorized time block may also be determined through direct user input or inference. Then, one or more rules associated with the assigned category restricting scheduling, of events on the user's calendar during the categorized time block may be implemented subject to the one or more exceptions.

Abstract: This disclosure concerns tools and techniques for debugging a quantum program (e.g., a program used to configure and control a quantum computing device). Because the state space of a quantum program is so much larger and less structured than the state space for a classical program, new techniques are required to help the program developer and coder determine whether or not their program is working correctly and to identify errors if not. The disclosed technology provides tools and techniques for debugging quantum programs using a classical computer.

Abstract: Techniques are described for efficiently embedding frame masks in a video stream. In some solutions, a computer implemented method includes operations for encoding a frame of video data comprising an array of pixels to generate an encoded video frame and transmitting the encoded video frame. The array of pixels can include foreground pixels and background pixels. The foreground pixels can have respective original luma values which are bounded within a first luma range. In certain examples, encoding the frame of video data can include converting the original luma values of the foreground pixels to updated luma values which are bounded within a second luma range. The second luma range can be shifted and/or compressed from the first luma range.

Abstract: An electronic device may include a housing (100), a display (102) disposed in the housing (100) and including an interface surface (112) arranged for user contact and a reference haptic (108). The interface surface (112) includes an active haptic output that provides a time-dependent haptic output and a reference haptic (108) disposed on the housing or the interface surface to provide a time-independent haptic output related to the time-dependent haptic output. The combination of active and reference haptics on an electronic device, such as a wearable display device, can convey information to a user without requiring the user to look at the device.

Abstract: Language interoperability between source code programs not compatible with an interprocedural static code analyzer is achieved through language-independent representations of the programs. The source code programs are transformed into respective intermediate language instructions from which a language-independent control flow graph and a language-independent type environment is created. A program compatible with the interprocedural static code analyzer is generated from the language-independent control flow graph and the language-independent type environment in order to utilize the interprocedural static code analyzer to detect memory safety faults.

Abstract: The present disclosure provides a method for intelligent automated chatting. A conversation with a user is performed by using a first identity of a first artificial intelligence entity. A message is received from the user in the conversation. Matching rates between the message and trigger contents of other artificial intelligence entities are scored. A second artificial intelligence entity is selected from the other artificial intelligence entities based on the matching rates. A conversation with the user is performed by using a second identity of the second artificial intelligence entity by switching from the first identity of the first artificial intelligence entity to the second identity of the second artificial intelligence entity.
