October Posts

In this episode of The Deep Dive, the hosts unpack October 2026 posts by SRE veteran Eri Bastos on the need for deliberate intentionality against entropy in complex systems. The conversation opens with a parachute whose dashboard only confirms the bag is zipped, not that the lines are anchored, and moves into friction as a design choice: Bastos contrasts a kitchen organized with mise en place against one where eggs live in a remote fridge and the stove ignition requires walking across the room, then maps the same pattern onto a retail system that forces an employee to retype an email across four disconnected apps. The hosts challenge the idea that this is just the cost of scale, treating it instead as deferred decisions that tax cognitive bandwidth, raise error rates, and drive burnout.Restore or It Didn’t Happen attacks the next illusion: a green check mark only means a backup script ran, not that the data is recoverable. Bastos shares a story in which policy-mandated tapes failed while a third tape created solely to practice the restore process was the only one that worked. The episode then turns to automation and expertise. In a rigid banking environment, Bastos automated away pure toil with Python and left; an earlier 40-hour monthly capacity report became a 15-minute script. The hosts discuss why leaders must reward the people who script themselves out of bottlenecks rather than the midnight heroes who keep the secrets, and why T-shaped engineers who cross boundaries—deep in one domain and competent in an adjacent one—are the ones who fix high-severity incidents that live in the gray areas between teams. The episode closes with a practical playbook: hunt for friction by watching real workflows, schedule an actual restore drill, incentivize obsolescence, and cross-train across silos.
