Pico. Without it, I'd still be searching how to quit vim :) But jokes aside, all kinds of real-time log aggregators make big difference for me. Once upon a time, I had acquired first huge customer and had to set up analytics service as a single-tenant deployment. I acquired better servers than usual, installed the service and started processing the traffic only to find out that we can handle only 1/50 of the contracted traffic. For the next 48h or so I pushed hundreds of changes to production and watched realtime charts in Splunk going from 1/50, 2/50 to 50/50. I saved the contract and saved the company and went to bed.
