windows windows11 dell

My 2025 Holiday Special - Windows 11 set-up fun!

My Windows 11 machine decided to go belly up just before Christmas, so I got to have some fun reinstalling Windows from scratch. I was hoping for a MacBook Pro for Christmas, but alas - it seems that Satan got me a fresh Windows installation to deal with instead.

How to fix "Decryption failed: Key not valid for use in specified state" in Azure CLI?

Ever thought Azure CLI was your reliable sidekick on Windows? Ha! You'd think so, until "Decryption failed: Key not valid for use in specified state" hits you out of nowhere. Fear not, though; for this is not just another Windows woe, but instead another fun trip down the rabbit hole that is authentication in the Microsoft world!

How to replace the default certificate in AKS?

Ah, the joys of Kubernetes wrangling – where even a "simple" cert swap feels like herding a bunch of ferrets on meth through a YAML labyrinth. Or so I've been led to believe by local ferret owners, when I tell them about my adventures with AKS. Anyway - this article explains how to replace the default certificate on an AKS cluster's ingress controllers.
