This article tries to bridge a gap in Microsoft’s documentation for the Azure IoT Edge deployment model. Namely – all different ways to deploy modules or module configurations to your Azure IoT Edge devices, and which takes precedence over which. Problem The documentation for Azure IoT Edge is surprisingly immature. As you go about your first projects, you will run into all kinds of gaps. One of the things I…Continue reading Azure IoT Edge order of deployment operations
Have you run into this puzzling error? It comes in a couple of flavors, but it boils down to you failing miserably when you run the create_hypertable() function on your PostgreSQL TimescaleDB database server! Annoyingly, it might mean that the whole function is missing (extension is not installed or loaded) or that your parameters are not properly parsed (an issue with your command). I know, that it sucks. I have…Continue reading How to solve “Npgsql: 42883: function create_hypertable(…) does not exist”?
So another simple one. (I just seem to run into all of the issues whenever I try to do the simplest thing with Docker!) Or with anything, I guess – but yeah, that’s another article then! Problem I was trying to run a Docker container called Syslog-ng, and had to add quite a few parameters in order to map the volumes and ports that I needed. Any time that I…Continue reading Solving “invalid reference format.” when trying to run “docker whatever”
This article documents a simple but annoying fix to an issue with Azure DevOps. In this particular case, an incoming webhook (configured as a service connection) would fail to fire, no matter what. It turns out that it’s a bug in Azure DevOps – who would have thought :) Luckily, there’s a fairly simple workaround available! Problem A colleague was configuring a new pipeline in Azure DevOps. It was supposed…Continue reading Azure DevOps incoming webhook just won’t fire? Easy (stupid) fix!
It’s the roaring twenties again, cloud is the hot stuff, and nobody needs a server anymore. Right? Nope! I’ve been involved in more on-prem or hybrid projects in the last 12 months than in the last 3-4 years combined. There are plenty of industries and valid uses for still setting up on-prem servers. And quite often, that includes setting up IIS (Internet Information Services) on said machines. And of course,…Continue reading How to install IIS (Internet Information Services) on Windows 10?
This article explains how you can move your Home Assistant’s SQLite database files to another location by mapping them to another volume in Docker. Using Docker on Windows. Which might not be a smart move, but it’s one I went with anyway. The article will explain how to do this with docker-compose, but the steps pretty much apply to vanilla docker as well. With that said – let’s move on!…Continue reading How to move the Home Assistant SQLite database in Docker on Windows?
This article describes the gotchas and weird one-offs that I’ve encountered with Azure IoT Edge so far. Consider them not-too-thoroughly tested quick fixes that aren’t significant enough to warrant an actual blog post themselves :) Okay – let’s get to them gotchas, then!

This article will explain how to run your arbitrary SQL commands against a Postgre SQL database running in a Docker container in Windows. That should be super simple, but since I never remember anything like this by heart, I had to google it – and turns out, either I didn’t know how to google this properly or people haven’t bothered to document this. So, let’s fix that. But first, why…Continue reading How to run SQL commands in a Postgre SQL Docker container?
Recently, I needed to host a web-based thingamajiggy in WordPress and needed to include a couple of custom libraries. For the sake of quick iteration, I decided to use a public FTP folder that I already had on the same server in order to host this. So I had configured a subdomain to host the files, and wanted to reference them from my WordPress site. Not quite a CDN, but…Continue reading How to modify CORS settings using a .htaccess file
