Abstract: One embodiment of the present invention sets forth a technique for controlling the operations of a consumer electronic (CE) device. A system includes a display device, CE device, and a remote controller with a touchpad. The CE device is configured to output a context-specific user interface for display by the display device. The particular user interface varies based on the operational context of the CE device. The remote controller sends signals that are detected by the CE device and control operations performed by the CE device. More specifically, the remote controller is used as a handheld pointing device to select operations through interactions with the context-specific user interface. A user may apply gestures to the touchpad that are interpreted based on the context-specific user interface to control the CE device.

Abstract: Embodiments provide techniques generating and managing encryption keys within a computing infrastructure. Embodiments provide a key publisher that generates and maintains key pairs in a list at a configurable interval. In addition, the key publisher publishes the list to other components within the computing infrastructure. Embodiments also provide a key consumer that downloads the list of encrypted key pairs and maintains an active window of keys to can be accepted from client devices that communicate sensitive data to the computing infrastructure. If the key consumer receives a key from a client device that is outside of the active window yet that corresponds to a future key pair in the list, the key consumer advances the active window towards the future key pair.

Abstract: Techniques for evaluating a second version of software. Embodiments selectively route incoming requests to software instances within a plurality of baseline instances and a plurality of canary instances, where the baseline instances run a first software version and the canary instances run the second software version. The software instances are monitored to collect performance data for a plurality of performance metrics. Embodiments calculate aggregate baseline performance metrics, where each of the aggregate baseline performance metrics is calculated based on the collected performance data for the plurality of baseline instances. For each of the performance metrics and canary instances, embodiments calculate a relative performance value that measures the collected performance data for the respective canary instance and for the respective performance metric, relative to the corresponding aggregate baseline performance metric. A final measure of performance is calculated for the second version of software, based on the relative performance values.

Abstract: Embodiments of the invention generally provide a method, a computing system, and a computer-readable medium configured to request, cache, and generate translations of paths through graph-based data representations. The computer-implemented method includes receiving a first request for translation, wherein the first request specifies a first path configured to identify first payload data. The computer-implemented method further includes determining whether a graph object stored in the local cache memory includes a first translation associated with the first path. If the local cache memory does not include the first translation, then the first translation is obtained from a remote computing device and stored in the graph object. If the local cache memory does include the first translation associated with the first path, then the first translation is obtained from the local cache memory. The computer-implemented method also includes obtaining the first payload data based on the first translation.

Abstract: Techniques for optimizing a plurality of parallel network connections for a digital content stream through a network between a plurality of content servers and a content player. Embodiments determine an indication of network performance for each of the plurality of parallel network connections. Additionally, upon determining that a first one the plurality of parallel network connections is underperforming, based on whether the indication of network performance associated with the first parallel network connection satisfies a threshold level of performance, the first parallel network connection is dropped. Upon determining that a total throughput for the digital content stream is less than a minimum threshold of network performance, embodiments select a content server with which to establish a new parallel network connection, based on historical network performance data associated with the selected content server, and also establishing the new parallel network connection to the selected content server.

Abstract: One embodiment of the invention sets forth an encoding server including components configured to encode a video stream associated with a content title for adaptive streaming. The video stream is first processed by a VC1 encoder to generate an encoded video stream comprising a multiple GOPs, each GOP including a key frame and having a different playback offset. The encoded video stream is then packaged such that the GOPs are stored in data packets of the packaged encoded stream. An SHI generator generates an SHI associated with the packaged encoded stream that includes a switch point associated with each GOP. Each switch point includes the playback offset associated with the corresponding GOP and the data packet storing the key frame of the corresponding GOP. The SHI associated with multiple packaged encoded video streams associated with the same content title and encoded to different playback bit rates have corresponding switch points.
