Abstract: A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

Abstract: Systems and methods for using a synchronization mechanism to dynamically update instrumentation during program execution are described herein. Using the synchronization mechanism, a decision tree structure of instruments can be avoided, saving processing resources. The synchronization mechanism can be a field or the like that is declared using a synchronization primitive. For example, the synchronization primitive can be a volatile or synchronized keyword in some programming languages. The field can refer to a currently-selected instrument implementation, thereby avoiding using a decision-tree structure to find a desired instrument implementation.

Abstract: In an approach to problem determination for cooperating web services, a computing device executes a debug script. The computing device discovers one or more web services based on a web service discovery mechanism. The computing device connects, by the debug daemon, with a debug probe to set a breakpoint on a web service. The computing device receives a file containing connection parameters. The computing device initiates a debug session with the web service using a designated connection channel. The computing device invokes a breakpoint handler function for the web service. The computing device sends commands to the debug probe, which forwards the debug commands to the web service. The computing device closes the debug session with the web service when the breakpoint handler function has run to completion.

Abstract: A source code is pre-processed to form a pre-processed source code. The source code refers to an external code in a separate file, and the pre-processed source code creates a single file that includes the source code and the external code. The source code is profiled to create profile information identifying a hot portion having a first degree of hotness. A set of environment parameter values is determined to be applicable to a data processing system where the application will execute. At a remote optimizing compiler, a selection of a set of compiler options from a knowledgebase corresponding to the profile information and the set of environment parameter values is caused and an object code resulting from compiling the pre-processed source code using the set of compiler options is obtained. The object code is optimized according to the profile information and the set of environment parameter values.
