Ubuntu 26.04 LTS replaces the 44-year-old C sudo with sudo-rs, a Rust rewrite. Learn what changes, why it matters for security, and what else ships.

The quality-cost tradeoff in DevOps is real but misunderstood. Learn why cutting quality to reduce cost usually increases total cost, and how to find.

Quality and safety are not the same thing in software engineering. Learn when to prioritize safety over quality, how to build guardrails without slowing.

High throughput and high quality are not mutually exclusive in DevOps. Learn how to increase deployment frequency without sacrificing reliability.

Platform engineering and DevOps solve different problems. Learn how platform teams build internal developer platforms, where DevOps still applies.

Golden paths give developers a paved road through infrastructure complexity. Learn how to design golden paths for your internal developer platform.

Spotify Backstage is the most popular open-source developer portal. Learn how to set it up, create software templates, build a service catalog, and integrate.

OpenTofu forked Terraform after the BSL license change. Compare features, compatibility, licensing, and ecosystem to decide which IaC tool fits your team.

Podman and Docker both run containers but differ in architecture. Compare rootless containers, daemon requirements, Compose support, and Kubernetes.

Build an internal developer platform that developers actually use. Learn the five layers of an IDP, common mistakes, build vs buy decisions.

Kubernetes clusters are often 60-70% over-provisioned. Learn practical cost optimization strategies: right-sizing, spot instances, autoscaling, namespace.

Ansible and Terraform solve different infrastructure problems. Learn when to use each, when to use both together, and how they complement each other.

Most DevOps dashboards track the wrong things. Learn which metrics actually predict engineering performance: DORA metrics, SLOs, and the metrics that drive.

Essential Git workflows for DevOps: branching strategies, interactive rebasing, cherry-picking, bisect debugging, and CI/CD integration.

Crossplane lets you manage cloud infrastructure using Kubernetes custom resources. Learn how it works, how it compares to Terraform, and when to choose.
