An embodiment of a method can create a directed acyclic graph (DAG) from a programmer specified set of computation units to solve, in a computer program, physics based simulations of physical systems, and the DAG can be used to analyze and debug the computer program. In this method, the computer program can be created by automatically determining dependency relationships in the set of computation units and automatically schedule their execution. The method can also automatically allocate memory for the computation units. |

Preventing barbage object accumulation on minimal runtimes while supporting an implicit deallocation programming experience
Computer-implemented techniques for preventing garbage object accumulation on minimal runtimes. The techniques include checking whether source code written in a source programming language that does not require the programmer to explicitly program when deallocation happens can run within a runtime that provides little or no support for implicit deallocation. At the same time, the techniques ensure that objects in minimal runtimes are deallocated in a timely manner. In one aspect, the techniques encompass generating a compile-time alert (e.g., an error or warning message) to a programmer of source code or halting compilation of the source code upon detecting a data type definition in the source code with the potential for reference cycles. With the techniques, the programmer is provided with an implicit deallocation experience while producing program fragments that interoperate with minimal runtimes that provide no or only minimal support for implicit deallocation (e.g., provide only reference counting). |

Systems and methods for translating data read from proxy APIs into computing code
A method for automatically generating sample code for an API for payment processing in a payment network includes reading an acquirer processor-specific API for payment processing in a payment network using an acquirer processor-specific API reader, generating acquirer processor-specific API data using the acquirer processor-specific API reader, converting the acquirer processor-specific API data into a format compatible with an output generator, and generating language-specific sample code by the output generator using the converted acquirer processor-specific API data and a language-specific template. |

Accelerated mathematical engine
Various embodiments of the disclosure relate to an accelerated mathematical engine. In certain embodiments, the accelerated mathematical engine is applied to image processing such that convolution of an image is accelerated by using a two-dimensional matrix processor comprising sub-circuits that include an ALU, output register and shadow register. This architecture supports a clocked, two-dimensional architecture in which image data and weights are multiplied in a synchronized manner to allow a large number of mathematical operations to be performed in parallel. |

Vocal guidance engines for playback devices
Systems and methods for vocal guidance for playback devices are disclosed. A playback device can include a first wireless transceiver for communication via a first data network and a second wireless transceiver for communication via a second data network. The device includes one or more processors and is configured to maintain a library that includes one or more source device names and corresponding audio content, the audio content configured to be played back via an amplifier to indicate association of a particular source device with the playback device via the first data network. The device receives, via the second data network, information from one or more remote computing devices, and based on the information, updates the library by: (i) adding at least one new source device name and corresponding audio content; (ii) changing at least one source device name or its corresponding audio content; or both (i) and (ii). |

Information display regarding playback queue subscriptions
Example techniques relate to playback queue subscriptions. An example implementation involves a computing system receiving, from a first computing device associated with a first user account, an instruction to enable subscription to a first playback queue associated with a first media playback system. In response to the instruction, the computing system enables second user accounts to subscribe to the first playback queue. The second user accounts are registered with respective second media playback systems in respective second household. The computing system receives, from a particular second media playback system, a request to subscribe to the first playback queue; and in response, sends one or more messages that update a control interface of the first control device to display a subscriber indication and (ii) sends one or more messages that populate a second playback queue of the particular second media playback system with audio tracks of the first playback queue. |

Designated share window for sharing content data
One embodiment provides a method, including: detecting an area of a display device of an information handling device of a user, designated as a share window; identifying, when the share window is in an active share state, a position of a first window on the display device with respect to the share window; and sharing, based upon the position of the first window on the display being within at least a portion of the share window, content data contained within the first window to a display device of at least one other user in communication with the information handling device of the user. Other aspects are described and claimed. |
