Abstract: Technologies are shown for secure management of a data file secured on a data file management blockchain that involve generating a genesis block for a data file management blockchain that contains a data file to be managed and signing the genesis block to commit the genesis block to the data file management blockchain. One or more transaction data blocks are generated for the data file management blockchain that each include a modification to the data file and the blocks are signed to commit them to the blockchain. In some examples, the modifications describe changes to the data file and the transaction data blocks are traced to the genesis block and a current data file generated by applying the modifications on the transaction data blocks to the data file in a sequence determined by an order of the one or more transaction data blocks in the data file management blockchain.

Abstract: Event data for an application execution is accessed from a table of logged events, the event data comprising a sequence, a hierarchy, and a start time and duration for each event. Dependency data for each event is also accessed to determine whether the start time for an event is dependent on the prior completion of at least one other event. A waterfall representation is then generated, the representation including an entry for each event in the sequence, with a start time and duration represented for each event. Based on the dependencies and hierarchy, it is determined, for each event with a start time that is later than the start time of an event which precedes it in the sequence, whether the event's start time is dependent on the prior completion of at least one preceding event. The start time for each event may then be advanced based on the determination.

Abstract: An augmented reality or virtual reality (AR/VR) device pairs with a companion device to augment input interfaces associated with an AR/VR application at the AR/VR device. In implementations, an AR/VR device determines a portion of a markup file that corresponds to an AR/VR scene of a plurality of AR/VR scenes in an AR/VR environment, and communicates the portion of the markup file to the companion device to cause the companion device to configure a companion user interface associated with initiating an action as part of the AR/VR scene. In response to receiving user input via the companion user interface, the companion device communicates the action to the AR/VR device to initiate the action. The AR/VR device receives input data from the companion device, and initiates the action for the AR/VR scene.

For example, a display region corresponding to the element may be highlighted or text regarding the element may be displayed. The hierarchy may be navigated by selection of items in the user interface itself, by selection of an item in the displayed information, by directional inputs, or any suitable combination thereof. Information displayed in the inspector may be configured by the application based on the identified element.

Abstract: Model placement metadata is defined and stored for a three-dimensional (“3D”) model. The model placement metadata specifies constraints on the presentation of the 3D model when rendered in a view of a real-world environment, such as a view of a real-world environment generated by wearable computing device like an augmented reality (“AR”) or virtual reality (“VR”) device. A wearable computing device can analyze the geometry of a real-world environment to determine a configuration for the 3D model that satisfies the constraints set forth by the model placement metadata when the 3D model is rendered in a view of the environment. Once the configuration for the 3D model has been computed, the wearable device can render the 3D model according to the displayed configuration and display the rendering in a view of the real-world environment.
