When I’m at home I have setup a Raspberry Pi to run Pi-hole and block pesky advertising. But. I am not always at home. I also bring my Macbook to work, customers, airports & hotels. I didn’t want to clutter up my system and install Pi-hole natively, so instead I used Docker To make starting/stopping Pi-hole easier I created a small shell script: #!/bin/bash case "$1" in install) docker pull pihole/pihole exit 0 ;; start) docker start pihole 2>&1 >/dev/null || docker run -d --name pihole -e WEBPASSWORD="Gloryhole" -e DNS1=1. ...

My ISP does not give me a static IP. It doesn’t change often, but in the rare case that it has changed I never discover it before I actually need it.

So. I wanted a very simple way of auto-updating the record. I didn’t want to bother with a thirdparty client from something like dyndns (and I didn’t want to pay for anything).

As I use Cloudflare as dns service for all domains I own I could just use their API and solve it with a oneliner, but doing it with Ansible is more readable

This probably takes a bit of explanation. My use case is the following: I wish to expose an internal Wiki outside the corporate network. To accomplish this I use an Azure AD Application Proxy. I also wish to restrict who has access to the application proxy and enforce multifactor authentication. This is easily accomplished by setting “User assignment required” in properties and adding a Conditional Access-policy. However. A really weird drawback in Azure AD is lack of support for nested groups. ...

**Update!: ** Please note that this post is made obsolete by Earlier this summer Microsoft announced Static Website Hosting for Azure Storage in public preview. An affordable way of hosting websites where you don’t need any server side logic. Instead of paying for, securing and updating my own Virtual Machine I decided to check it out. This of course led me deep down a rabbit hole thinking about resurrection my personal website in some way. ...

Atlantic Ocean Road

May 1st marks the start of Stikk Ut. A local initiative to get people up from their sofa and get outside.

As the last day of april had amazing weather I decided to jump start the whole thing. Last leg for the day was a drive through the Atlantic ocean road and a quick stop at Svevestien and Storseisundet

On my way back from Microsoft LEAP in Redmond I took advantage of Icelandair’s offer to have a “free” layover in Iceland. “free” because staying in Iceland, even if it’s just for two days isn’t cheap. For my only full day I joined a tour along the southern coast and among the stops was the black beach Reynisfjara. I have no idea who the couple having their wedding that day was, but congratulations to them. ...

To change VM Size when your virtual machines are part of an availability set can be a pain in the Azure Portal. Especially if the new size you want is not available on your current cluster and the resources have to be moved as well.

The entire process is a lot easier to do with powershell

Get-ADUser -SearchBase "ou=users,dc=contoso,dc=com" -Filter * -Properties Name, EmployeeNumber, UserPrincipalName, Manager | where {$_.Manager -eq $null} | ft Name, EmployeeNumber, UserPrincipalName, Manager

Because “Manager” is an extended attribute in Active Directory you can’t use -Filter {Manager -notlike “*“} like you would with basic attributes
