Abstract: A system is configured for machining a workpiece (100), the workpiece includes an interior surface (110) that defines an internal passage (112). The system includes an electrode (116) located within the internal passage and electrically isolated from the workpiece, an electrolyte supply, a power supply, and a remover. The electrolyte supply is configured for circulating an electrolyte in a gap between the electrode and the workpiece. The power supply is configured for applying a voltage between the electrode and the workpiece to facilitate smoothing the interior surface. The remover is configured for completely removing the electrode from within the internal passage after smoothing the interior surface.

Abstract: A self-healing build pipeline architecture for a software application build job across a distributed computer platform comprises a public API that receives configuration data describing the build job, stores the configuration data in a decentralized database, serves requests to/from a pipeline tracker API, and stores states of build pipelines during the build job. The decentralized database stores the configuration data and a project identifier for the build, and metadata regarding states of the build pipelines collected across the distributed computer platform. The pipeline tracker API runs local to the build environment in the distributed computer platform and sends a build status to public API for updating the decentralized database. For any failures in any of the build pipelines, the state is retrieved from the decentralize database and a new build pipeline is triggered locally that resumes from the failed state to provide a self-healing build pipeline architecture.

Abstract: A grease gun comprising a body having first and second chambers, first and second pistons within those first and second chambers, primary and secondary grease channels, a grease outlet and an actuator, is provided. Actuation of the actuator by a user causes first and second pistons to move within first and second chambers. The body may further comprise a pressure sensitive spool which allows the grease gun to move from a high flow/low pressure operation to a high pressure/low flow operation when there is a grease blockage that causes an increase in the pressure in the body.

Abstract: The present embodiments relate generally to DC-DC converters and more particularly to a scheme for providing current sharing between parallel converters in a multiphase configuration. In some embodiments, a cycle-by-cycle instant correction to the compensation signal offset is provided based on the current share error between the paralleled converters so as to achieve improved instant current share performance.

Abstract: Optimizing transaction times for distributed databases is described. A system receives a request which specifies an identifier of a database record associated with a distributed database. If the request is associated with a primary database of the distributed database, any user-defined function is associated with the database record in the primary database, and any associated user-defined function does not require any call that is external to a subnet and/or a firewall associated with the primary database, then the system executes, within the subnet and/or the firewall associated with the primary database, each associated user-defined function for the database record in the primary database. The system outputs a result which is based on executing any associated user-defined functions.

Abstract: A request for a transaction between a client system and a server system may be processed. The transaction may be associated with transmission of data between the client system and the server system. The data may be encrypted using a transient encryption key to form encrypted data. The transient encryption key may be a synced-clock random number configured to automatically change when a designated time interval elapses. The encrypted data may be transmitted between the client system and the server system.

Abstract: Methods and systems are described for using cache objects to store events for adding corresponding objects in a blockchain. In one implementation, a first cache object is identified. The cache object stores events published responsive to updates, insertions, or deletions of records in a database object. An identifier for the cache object is based on a time window with which the cache object is associated, and an identifier for the database object. Events are retrieved from a cache that includes the cache object, based on the identifier for the cache object. The events were stored in the cache object during the time window. A block is added to a blockchain. The block's payload includes objects corresponding to a subset of the events.

Abstract: Technologies are provided for a cloud computing platform (CCP) to request a transaction via a third-party vendor and receive a transaction response result of that transaction from another cloud computing platform having a serverless capability such that at least part of the transaction occurs at the other cloud computing platform. A transaction request having a specific transaction type (TT) is sent to an adapter, which sends another call with the transaction request to the public cloud. The specific TT corresponds to a particular serverless function (SF) of the third-party vendor. A particular template t corresponds to the specific TT. The particular template is a code statement that follows a standard code definition written in the proprietary programming language of the CCP. The other cloud computing platform invokes the particular SF to generate a transaction response that is consumable by the CCP.

Abstract: Systems, methods, and non-transitory computer-readable media can receive, via a user interface provided to a user, test device information identifying one or more user computing devices as test devices. An advertisement request is received from a first user computing device. A determination is made that the first user computing device is identified as a test device. A test advertisement is transmitted to the first user computing device based on the determination that the first user computing device is identified as a test device.
