This new observing mode is pushing the VLA beyond its intended use and finding new, compelling science. The challenges of this effort are increasingly common in astronomy, particularly in the study of the transient universe. My current effort is on improving the parallelization and robustness of my radio transient search; these are issues common to many in high-performance computing. In the longer term, I am interested in developing the concept of \emph{real time science detection} as a solution to the challenges of big data. Real time detection of radio transients allows us to throttle the data stream by saving only candidate events. This approach can also be applied to other fields in astronomy, but requires reimagining the observatory.  planned serendipity  \section{Science}  Fast radio transients \index{radio transients} are pulses of dispersed radio emission lasting less than 1 second. Slower radio transients originate predominantly in synchrotron emission, while faster transients are caused by coherent processes. Furthermore, at timescales faster than 1 second, propagation through the Galactic plasma induces dispersion, the frequency-dependent arrival time quantified by dispersion measure (DM), that begins to be detectable at MHz through GHz radio frequencies.
