Software engineering case studies from the field — like turning 15 overloaded Kubernetes pods into 2 healthy pods — written by a senior backend engineer who ships fixes, not just theories.
Manual testing feels faster today — but it's quietly costing businesses thousands down the line. Here's why most developers skip automation anyway, and what it's really costing you.
A few days ago, I found out that Bun had been completely rewritten from Zig to Rust. At first, I thought it was just another programming language migration, but after reading Jarred Sumner's engineering blog, it completely changed the way I think about software rewrites and AI.
Our team struggled with a service that kept triggering resource alerts even after scaling to 15 Kubernetes pods. Instead of a full rewrite, I investigated the root causes and reduced it from 15 overloaded pods to just 2 healthy ones.
