A Multidisciplinary Guide To Cloud Cost Intelligence
Cloud cost intelligence has moved beyond simple cost-cutting. Now, it’s about creating value. Cloud bills continue to rise, and workloads are becoming increasingly complex. Teams also need to understand what they’re spending, why, and how that spend ties to business results. FinOps has become the framework for bringing finance and engineering together. It’s helping teams manage costs, improve margins, and plan with confidence. But challenges remain.
The AI Velocity Paradox
AI-powered coding alone isn’t enough. True software delivery velocity requires end-to-end automation and intelligent governance across the entire lifecycle. Harness enables organizations to escape the AI Velocity Paradox by unifying speed, safety, and resilience, turning rapid development into a sustainable competitive advantage. The widespread adoption of AI coding assistants is transforming software engineering.
This Developer Built an App That Doesn't Spy on You
Rizel Scarlet (Staff Developer Advocate at Block) tackled a problem every developer should care about: apps that spy on users before they even know they need the service. Her solution? Build a privacy-first pregnancy app using AI agents and decentralized web nodes. This isn't just about pregnancy apps - it's about the future of user data ownership.
Docker Daemon Logs: How to Find, Read, and Use Them
Sometimes Docker behaves in ways that catch you off guard—containers don’t start as expected, images pause during pull, or networking takes longer than usual to respond. In those moments, the Docker daemon logs are your best reference point. These logs capture exactly what the Docker engine is doing at any given time. They give you a running account of system state, performance signals, and events that help you understand what’s happening beneath the surface.
Recapping SEV0 San Francisco 2025
Earlier this week, we gathered in San Francisco for our second SEV0—almost a year after our very first event. SEV0 has always been about shining a light on the biggest challenges (and opportunities) in incident response. Last year, we were still talking about the fundamentals: blameless culture, strong processes, and lessons from the best in reliability. This year felt different. AI has moved from background noise to front and center in every conversation, every team, everywhere.
Automation Observability: See It, Fix It, Skip the Firefighting
IT leaders know the drill. An alert storm rolls in and the tickets pile up. Your team scrambles to piece together root causes before service degradation kicks in. But the firefighting rages on, even when you have enough dashboards, monitoring, and alerts to light up a Christmas tree. Enterprise leaders need to quit burning budget on shiny dashboards that look good in the boardroom but do nothing to stop outages in the real world.
The Unit Economics Of Watering My Lawn: A Lesson On Runaway AI Costs
My wife and I spent hours this summer at home digging in the dirt. We planted new shrubs and perennials and created a small vegetable garden. We spread many square yards of fresh topsoil and grass seed over areas of lawn that needed rejuvenation. It turns out, I should have done all that landscaping with a FinOps leader’s mindset — before my water bill tripled when I wasn’t looking.
