Abstract: A load balancer determines a first usage load for a first server group that is one of a plurality of server groups associated with a resource. The load balancer determines a usage total for a user group of a plurality of user groups assigned to make requests for the resource via the first server group. The load balancer determines an assignment of the user group to make requests for the resource via the first server group or a second server group of the plurality of server groups based on the usage total of the user group, the first usage load of the first server group, and a second usage load of the second server group. The load balancer routes requests for the resource by the user group to the first server group or the second server group based on the assignment.

Abstract: A system described herein may use automated techniques to programmatically validate software-under-test (“SUT”) using different sets of test cases for different functions of the SUT. The system may generate the different sets of test cases based on a selected test methodology and a self-description of the SUT function calls, function arguments, and/or argument types. The system may convert the test cases to executable-code and/or network messaging that can be used to call the SUT functions with different input combinations for the arguments and/or argument types of the SUT functions, and that can capture the output that results from each function call.

Abstract: A pipeline plug having a seal assembly and a slip assembly coupled to the seal assembly. The slip assembly moves from a retracted position to an expanded position when the seal assembly moves from a disengaged position to an engaged position. The slip assembly frictionally engages the internal wall of a pipe when in the expanded position. The force exerted on the pipeline plug by fluid within the pipe increases the force by which the slip assembly engages the internal wall of the pipe. The plug is removable from the pipe without damaging the plug by moving the seal assembly back to the disengaged position. A method of sealing a pipeline using the pipeline plug.

Abstract: Apparatus for tapping a hole in a pipeline adapted to be attached to a support assembly having sealed communication with the exterior of a pipeline and having a tapping machine body with a boring bar rotatably supported therein with a circular cutter at the lower end thereof, a feed screw rotatably supported by the tapping machine body for axially positioning the boring bar, a hydraulically powered boring bar drive assembly within the tapping machine body driving the boring bar, a hydraulically powered feed screw drive assembly within the tapping machine body driving the feed screw and an auxiliary drive shaft affixed to rotate the feed screw drive assembly extending exteriorly of the tapping machine body and adapted to receive supplementary mechanical rotary energy for rotation of the feed screw so the boring bar can be retracted if hydraulic power is lost. A pressure compensation system permits the apparatus to be operated in a subsea environment.
