Plenty of content this week!

Tuning Linux Swap for Kubernetes: A deep-dive article on why and how to correctly configure and tune Linux swap settings when running Kubernetes workloads.
Production-Grade Container Deployment with Podman Quadlets: How to deploy and manage containers using Podman and Quadlets, which leverage native systemd unit files for production-ready setups.
Security Contexts in Kubernetes: A breakdown of Kubernetes Security Contexts, covering settings like runAsUser, capabilities, and SELinux options to tighten pod security.
A Small Vanilla Kubernetes Install on NixOS: A guide to setting up a minimalist, declarative Kubernetes cluster using the NixOS operating system (too complex if you ask me).
etcd Hardware Requirements: The official etcd documentation on hardware considerations (especially disk speed and network latency) for optimal performance and cluster stability.

RavynOS: The macOS-like OS on a FreeBSD Kernel: The project page for RavynOS, an operating system that aims to achieve macOS-like design and application compatibility using the FreeBSD kernel.
We’re (now) moving from OpenBSD to FreeBSD for firewalls: The author is moving their firewalls and VPN servers from OpenBSD to FreeBSD because FreeBSD offers clearly superior network performance, particularly on a 10G network, despite OpenBSD having served them well for years.
Why the BSDs?: A philosophical and technical discussion on the key differentiators and advantages of using the various BSD operating systems.
Static Web Hosting Performance Comparison: A performance comparison of serving static web files across FreeBSD, SmartOS, NetBSD, OpenBSD, and Linux on low-power Intel hardware.
systemd.preset Man Page: Official documentation for systemd.preset, which defines default enablement/disablement policies for services at installation time.
Setting up Software TPM (swtpm) for Libvirt VMs: A small post on how to install swtpm to provide TPM emulation capabilities to libvirt VMs (I wasn’t aware swtpm even existed!).

Spec-Driven Development for Infrastructure Automation: An article exploring the methodology of using clear, formal specifications (like APIs or schema) to drive the automated creation and management of infrastructure. I’m both amazed and scared about SDD.
Terraform Provider for OpenWrt: A fun hack/project that creates a custom Terraform provider to manage OpenWrt router configurations declaratively.
Self-Hosting DNS for No Fun But a Little Profit: A candid look at the challenges and minor financial/control benefits of running your own recursive DNS server.
Declarative RPM: A blog post discussing how to achieve declarative package management for RPM-based systems, taking inspiration from the Nix/Guix philosophy.
