Abstract: A program is executed using a call stack and shadow stack. The call stack includes frames having respective return addresses. The frames may also store variables and/or parameters. The shadow stack stores duplicates of the return addresses in the call stack. The call stack and the shadow stack are maintained by, (i) each time a function is called, adding a corresponding stack frame to the call stack and adding a corresponding return address to the shadow stack, and (ii) each time a function is exited, removing a corresponding frame from the call stack and removing a corresponding return address from the shadow stack. A backtrace of the program's current call chain is generated by accessing the return addresses in the shadow stack. The outputted backtrace includes the return addresses from the shadow stack and/or information about the traced functions that is derived from the shadow stack's return addresses.

Abstract: The present disclosure generally relates to partial integrated core-shell investment casting molds that can be assembled into complete molds. Each section of the partial mold may contain both a portion of a core and portion of a shell. Each section can then be assembled into a mold for casting of a metal part. The partial integrated core-shell investment casting molds and the complete molds may be provided with filament structures corresponding to cooling hole patterns on the surface of the turbine blade or the stator vane, which provides a leaching pathway for the core portion after metal casting. The invention also relates to core filaments that can be used to supplement the leaching pathway, for example in a core tip portion of the mold.

Abstract: Various mechanisms and workflows are described that can utilize power and/or carbon footprint-based metrics to manage storage unit usage and/or configuration, which can provide a more efficient and environmentally friendly computing environment. In some example configurations, storage system management mechanisms collect power consumption for storage units (e.g., individual drives, storage shelfs, nodes, clusters) and can utilize the power consumption information with other storage unit characteristics to generate power and carbon footprint metrics.

Abstract: The technology described herein is generally directed towards relating inconsistent identifiers of the same entertainment data entity (such as a movie) to one another. A global identification service, given an entertainment data entity identifier, returns identifier information and related data according to other naming conventions. Canonicalization rules and standards provide a consistent identifier for variously named/identified entertainment entities. A canonicalized identifier (or another identifier) may be part of a URN-based naming convention that identifies the entertainment data entity, as well as the organization that owns the entity and an authority within the organization that is responsible for that entertainment data entity.

Abstract: An image sensor includes a plurality of pixels, each pixel belonging to one of N subframes each characterized by (a) a same exposure-time sequence that includes a short exposure-time alternating with a long exposure-time, and (b) a respective temporal offset equal to a multiple of the short exposure-time. A method for encoding a video stream captured by the image sensor includes (i) for each subframe, linearly combining a long-exposure image, captured at the long exposure-time, and a short-exposure image, captured at the short exposure-time, to yield a residual image, (ii) combining at least some of the long-exposure images from the N subframes to yield a full-frame image having a higher resolution than any long-exposure image, (iii) encoding the full-frame image into a base layer of the video stream, and (iv) encoding at least some of the residual images from the N subframes into an enhancement layer of the video stream.

Abstract: Embodiments as disclosed herein provide a search system with an pre-indexing filter that provides both a sophisticated and contextually tailored approach to filtering documents and a corrector that is adapted to alter a document that has been designated to be filtered out from the indexing process and determine if the altered document should be indexed. The alteration of the document may be tied to the attributes, rules or thresholds used to initially filter the document from the indexing process. The filtering criteria can thus be tailored to a specific context such that both the initial filtering and the alteration process may be better suited for application in that context.
