kpatch
kpatch is a Linux dynamic kernel patching infrastructure which allows you to patch a running kernel without rebooting or restarting any processes. It enables sysadmins to apply critical security patches to the kernel immediately, without having to wait for long-running tasks to complete, for users to log off, or for scheduled reboot windows. It gives more control over uptime without sacrificing security or stability.

Operational Considerations for Managing Stateful Workloads
When managing stateful workloads, whether in Kubernetes or traditional infrastructure, operational concerns like isolation, lifecycle management, security, disaster recovery, scalability, and observability take center stage. While the examples focus on AWS, PostgreSQL, and Kubernetes, the principles and best practices discussed here are broadly applicable to any environment. This article approaches these topics from an operations perspective, prioritizing reliability, maintainability, and resilience. The goal is not just to run a database, but to ensure it operates efficiently, scales properly, and remains secure in real-world conditions. We’ll explore key aspects of running stateful workloads, from managing failure domains to ensuring observability, and how these impact both operations teams and developers. Whether you’re running a database in a cloud-native setup or on bare metal, these strategies will help you build a robust, well-managed system.
Why Our Pods Were Breaking Bad (and How We Fixed Them)
In this article, we’ll walk through the process of diagnosing a memory leak, analyzing the root cause, and implementing effective solutions to mitigate its impact. We’ll explore practical steps that any application, regardless of the underlying stack or architecture, can follow to troubleshoot and optimize performance.

Staying on Nix
I have been using Nix regularly since roughly 2019, when I set up my primary build server to use Nix to manage the various toolchains, though it wasn't until 2022 that I really invested heavily, and I'm now using Nix in combination with other more traditional DevOps tools to provision and manage more than 10 physical machines and 50 VMs in my homelab.
