A practical, sysadmin-grade comparison of Fail2ban and CrowdSec: how each detects and blocks malicious traffic, the architecture that separates them (local log analysis vs community-shared intelligence), real configuration and commands, honest pros and cons, and when to run Fail2ban, CrowdSec, or both.
npm vs pnpm in 2026: official benchmark data including the Rust-based pnpm 12, workspace workflows, and the supply chain case for switching, from blocked build scripts and minimum release age to git hooks and editor tooling.
After 90 days running self-hosted Immich instead of Google One for our family photos: what worked, what it actually costs, why your data finally stays on hardware you own, and the honest gaps that are still missing for families, straight from the project's own roadmap and issue tracker.
A sysadmin-grade guide to Docker Sandboxes for AI agents: microVM isolation layers, credential injection that keeps API keys out of the sandbox, sbx secret management, the MCP gateway, and what is not isolated by default.
A sysadmin-grade comparison of Docker Compose and Kubernetes for running many self-hosted apps: where Compose starts to hurt, how k3s changes the calculus, and how rootful Kubernetes is actually secured with RBAC, admission control, securityContext, seccomp, and network policies, and how that differs from rootful Docker.
A practical, sysadmin-grade comparison of Docker and Podman for running many self-hosted apps: Compose vs Quadlet, rootful vs rootless security and host-tool debugging, Watchtower vs podman auto-update, Docker API compatibility, and when Kubernetes is the real answer.
A developer-focused walkthrough of the Systhoughts cron expression playground: build and edit expressions, read plain-English explanations, and inspect next runs on a timeline. Four worked examples, the weekday/dialect/timezone mistakes to avoid, and small challenges to try.
