An online performance venue system and method including a central server and a plurality of user terminals allows users to meet, communicate, learn, and perform. The sensor includes a sample chamber to hold a sample in electrolytic contact with a working electrode, and in at least some instances, the sensor also contains a non-leachable or a diffusible second electron transfer agent. One or more instances of the hardware synthesis job to run with the respective one or more different timing constraints may be automatically spawned. Dominant peaks in the signal are thereby substantially reduced.
