    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. In this article I'll describe what happened and share my experience setting up a fresh Windows 11 installation — it wasn't pleasant. Maybe this will serve as feedback for Microsoft to improve the Windows setup experience.

    Sharing your meeting recordings has never been more... Confusing!

    This is not my typical blog post, where I introduce a problem, talk a little bit about the background, dive in to the technical stuff, rant for a while and then explain how to get around the issue (or even fix it!) No - this time, in the spirit of ranting, I'm just venting. Well, and in the process I do share what actually does work - so I guess it IS a normal blog post after all. But it IS rantier than usual. You have been warned!

    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.
