AI Coding Made Us Faster. Why Did Incidents Increase?

Engineering teams that adopt AI‑coding assistants see immediate gains in velocity—larger pull requests, shorter cycle times, and faster sprint completions. However, DORA data shows that the same acceleration often leads to a higher change‑failure rate, causing more hot‑fixes and on‑call...

Observability Tools Weren’t Built for AI Debugging

AI‑assisted code generation is accelerating software delivery, but developers are now spending more time fixing AI‑generated bugs. The root cause is not model weakness but a data gap: observability platforms provide sampled metrics and traces while omitting payloads, headers, and...

Frontier AI Models Haemorrhage Sensitive Data

Enterprise AI agents built on frontier large‑language models are unintentionally exposing confidential information, a new study finds. Researchers measured privacy violations across 125 simulated corporate tasks and observed leakage rates ranging from 16% to 51%, with higher task‑completion success correlating...

Think the Technical Interview Is Dead? Think Again

Technical interviews are undergoing a rapid transformation as AI reshapes how candidates are evaluated. While algorithmic LeetCode‑style questions remain common at FAANG firms, their weighting is decreasing and many companies are experimenting with AI‑assisted coding stages. Startups are leading the...

DORA Metrics Are Lying to You and AI Is Making It Worse

DORA metrics have long served as a DevOps shorthand for delivery performance, but they only measure the flow of changes, not the team’s grasp of the underlying systems. The rise of AI‑generated code lets engineers ship faster while the code’s...

The Reality of Being a Senior Engineering Manager

The article explains how senior engineering managers (EMs) move beyond team‑level execution to shaping system‑wide strategy. It highlights that the role is defined by influence across multiple teams, not by the size of direct reports. Senior EMs must build trust,...

What 16 Years of Software Engineering Taught Me About Growth

Over a 16‑year span across Indian service firms, North‑American product companies, and a personal startup, the author discovered that technical excellence alone does not create great engineers. Four practices—consistent documentation, active community engagement, deliberate experimentation, and managing imposter syndrome—proved essential...

5 Ways to Operationalize Generative AI in Legacy Systems

A recent study of a 70,000‑file legacy codebase demonstrates that generative AI can automate maintenance only when the surrounding environment is re‑engineered. The researchers identified five design patterns—memory‑limit optimization, historical‑context structuring, agentic task orchestration, output stabilization, and build‑pipeline modernization—that turn...
