It’s raining. One of us tries to use a laptop to shield the phone while the other puts a jacket over their head – not to keep themselves dry, but to stop the laptop getting drenched, all the while trying not to break the tether between computer and phone. Walking around town with this set-up at dusk may not be the smartest idea, nor the most efficient way to find bugs, but we’re trying to solve an issue.
