Abstract: Embodiments provide techniques for managing access to files on a computing system. An example method generally includes receiving, from an application, a request by a user to access a specified file on a file system through the application. A permission record is retrieved from a permission repository based on information about the application, the user, and the specified file. A determination is made of whether the user has permission to access a directory in the file system in which the specified file is located, and a determination is made of whether the application is allowed to access the specified file. Based on determining that the user has permission to access the directory in which the specified file is located and determining that the application has permission to access the specified file, the specified file is retrieved from the directory, and the application is granted access to the specified file.

Abstract: Systems and methods for wire arc additive manufacturing systems that print in horizontal orientations are described. Horizontal WAAM 3D print systems comprise metal 3D print systems in a horizontal orientation with one or more robots operating concurrently on a work piece using one or more wire feeds and a rotating, horizontal build plate.

Abstract: A self-guiding automaton includes sensors, a hardware processor, and a memory storing a self-guidance software code. The hardware processor executes the self-guidance software code to detect a location and/or travel path of one or more human being(s) in a pedestrian environment using the sensors, and identify a self-guided path forward in the pedestrian environment based on the location and/or travel path of each human being(s). The self-guidance software code also determines a social cue for communicating the self-guided path forward to the human being(s), detects any change in the location and/or travel path of each human being(s) using the sensors, determines a pedestrian safety score of the self-guided path forward based on the location and/or travel path and any change in the location and/or travel path of each human being(s), and moves the automaton along the self-guided path forward if the pedestrian safety score satisfies a safety threshold.
