Abstract: Implementations are described herein for automatically identifying, recommending, and/or effecting changes to a legacy source code base by leveraging knowledge gained from prior updates made to other similar legacy code bases. In some implementations, data associated with a first version source code snippet may be applied as input across a machine learning model to generate a new source code embedding in a latent space. Reference embedding(s) may be identified in the latent space based on their distance(s) from the new source code embedding in the latent space. The reference embedding(s) may be associated with individual changes made during the prior code base update(s). Based on the identified one or more reference embeddings, change(s) to be made to the first version source code snippet to create a second version source code snippet may be identified, recommended, and/or effected.

Abstract: Disclosed are systems and methods for improving interactions with and between computers in content generating, searching, hosting and/or providing systems supported by or configured with personal computing devices, servers and/or platforms. The systems interact to identify and retrieve data within or across platforms, which can be used to improve the quality of data used in processing interactions between or among processors in such systems. The disclosed systems and methods automatically analyze a live streaming media file, and identify portions of the media that are highlights. The content classified as a highlight can be shared across social media platforms, and indexed for searching respective to attributes of the video content. The streaming and highlight media content is renderable in a novel, modified video player that enables variable playback speeds for how content is classified, and enables on-demand selections of specific content portions and adjustable rendering displays during streaming.

Abstract: Many headset devices, such as virtual reality helmets, present visuals that respond to the user's motion, such that a rotation of the user's head causes the visual to be re-rendered from a correspondingly rotated perspective. The lag between the user's motion and the updated rendering from the new perspective may be perceivable even at high framerates, and may induce unpleasant feelings such as vertigo. Instead, headset devices may respond to detected motion by identifying a displacement of the physical location of the visual that causes it to maintain a physical position relative to a stationary reference point. The display is operatively coupled with a displacer, such as actuators or a projection adjustment, that are engaged to displace the display according to the identified displacement and maintain a physical location of the visual relative to the stationary reference point (e.g., until the visual is re-rendered from the updated perspective).

Abstract: An in-ear device includes a housing shaped to hold the in-ear device in an ear, and an audio package, disposed in the housing, to emit sound. A tympanic membrane measurement unit (TMMU) is structured to measure a movement of a tympanic membrane in the ear caused by external sound received by the tympanic membrane, and a controller is coupled to the audio package and the TMMU. The controller includes logic that when executed by the controller causes the in-ear device to perform operations. The operations include measuring a movement of the tympanic membrane, and in response to measuring the movement of the tympanic membrane, outputting sound from the audio package to destructively interfere with the external sound received by the tympanic membrane.
