Abstract: A method includes receiving, at a cloud storage system, a request to access a file from an external application on behalf of a first user account, determining, based on one or more access control lists (ACLs) associated with a shared folder, that the external application is not allowed to access the file on behalf of the first user account, and receiving, from a user device associated with the first user account, a message authorizing the external application to access the file on behalf of the first user account. The method further includes modifying the ACLs associated with the shared folder containing the file and a subfolder, and allowing the external application to access the file on behalf of the first user account based on the user information of the first user account and the application information of the external application in the modified ACLs.

Abstract: In an example embodiment, an issuer system receives payment card information from a payment processing system, wherein the payment card information is received from a payment card via a user computing device using near field communication. The issuer system generates an unpredictable number for the payment card and communicates the unpredictable number to the payment card via the payment processing system and the user computing device. The payment card calculates a cryptographic checksum based on the unpredictable number and a shared secret and communicates the checksum to the issuer system via the user computing device and payment processing system. The issuer system verifies the checksum using the shared secret and the unpredictable number. The issuer system generates a token associated with the payment card and transmits the token to the user computing device via the payment processing system for use in an online transaction.

Abstract: Embodiments of the present invention are directed to an adjustable-incline climbing wall. The climbing wall includes one or more climbing panels supported by a frame and a system for adjusting the incline of the frame to provide a climbing wall of a desired incline. The incline of the climbing wall may be adjusted by activating an actuator, which extends the upper portion of the frame a distance from a support wall, tilting the climbing wall to a desired incline. When the climbing wall is substantially vertically oriented, the system for adjusting the incline of the climbing wall may extend only a small distance from the support wall so that the adjustable-incline climbing wall has a relatively small footprint. In some embodiments, the climbing wall may also include one or more fitness accessories that can be brought to an optimal height for a particular user through adjustment of the climbing wall incline.

Abstract: Systems and methods for adjusting operating parameters of at least one pipelined software asset. Within a pipelined environment, an agent software asset is inserted immediately preceding a software asset whose operating parameters are to be adjusted. The agent software asset receives data and/or data sets from a user and such data and data sets are inserted/used by the software asset. The agent software asset also allows for a reporting of the output of other software assets to thereby provide users with intermediate outputs from the pipelined environment.

Abstract: Systems and methods for managing software resources such as machine learning/artificial intelligence models. The system includes a number of components that provide versioning services to both software resources and to data sets. A data storage component also addresses storage/retrieval functions for the system. A user interface element is also present to provide users with both a GUI and a command line interface. An assessment element assesses user selected software assets for project inclusion, with the assessment being based on good software development principles and practices. Once a project of selected software assets has passed the assessment stage, the software assets are pipelined for execution by an execution unit. The outputs of the execution unit are sent to a data output module automatically populates predetermined and preconfigured templates with the outputs to produce reports. The outputs may be final outputs or they may be intermediate results produced by the software assets.
