What if the reason your server keeps crashing has nothing to do with a bug in your code?

In this episode, Lawrence shares how a gaming server struggled with slow responses, delayed messages, and unexpected crashes, yet every test showed nothing wrong. After three frustrating weeks of debugging, he discovered a hidden difference between the production and testing environments: RAID 5 storage. Combined with an overloaded logging queue, this setup caused serious performance issues during peak traffic. The surprising solution? A single line of code that improved message throughput by 10 times! Laurence shares valuable lessons about server performance, production debugging, and why comparing system environments matters. Discover how recognizing patterns, questioning assumptions, and looking beyond the code can save engineers weeks of troubleshooting.

What happens when you do everything right, but the numbers keep telling you something is wrong? In this deeply personal episode of The Cutover, Lawrence Spector shares how months of warning signs, rising blood sugar, and a type 2 diabetes diagnosis eventually led to the real answer: LADA, often called type 1.5 diabetes. He reflects on the shock of starting insulin, losing his father during the same difficult period, and learning that effort alone cannot fix a plan built on the wrong diagnosis. Drawing from 25 years in engineering, Lawrence connects health, leadership, and system failures through one powerful lesson: when the plan stops working, question the diagnosis. He also shares how life with LADA has become manageable, even if the condition is always present.

(7:31) Losing his father while adjusting to a new diagnosis
(8:18) Lessons from treating the body like a system
(9:29) Why failed plans should make us question the diagnosis
(10:10) Learning to live with LADA, insulin pumps, and CGMs
