  • Tech Tips – Adding Linting to C# Projects

    Among the Javascript/Typescript community, ESlint and Prettier are very popular ways to enforce some standards and formatting within your code. In trying to find similar functionality for C#, I did not find anything as ubiquitous as ESLint/Prettier, but there are some front runners. Roslyn Analyzers and Dotnet Format John Reilly has a great post on…

  • Deprecating Microsoft Teams Notifications

    My first “owned” open source project was a TeamCity plugin to send notifications to Microsoft Teams based on build notifications in Teamcity. It was based on a similar TeamCity plugin for Slack. Why? Well, out of necessity. Professionally, we were migrating to using MS Teams, and we wanted functionality to post messages when builds failed/succeeded.…

  • Pulling metrics from Home Assistant into Prometheus

    I have setup an instance of Home Assistant as the easiest front end for interacting with my home automation setup. While I am using the Universal Devices ISY994 as the primary communication hub for my Insteon devices, Home Assistant provides a much nicer interface for my family, including a great mobile app for them to…

  • Bruce Lee to the Rescue! Health Checks for .NET Worker Services

    As we start to develop more containers that are being run in Kubernetes, we encounter non-http workloads. I came across a workload that represents a non-http processor for queued events. In .NET, I used the IHostedService offerings to run a simple service in a container to do this work. However, when it came time to…

  • MMM-PrometheusAlerts: Display Alerts in Magic Mirror

    I have had MagicMirror running for about a year now, and I love having it in my office. A quick glance gives my family and I a look at information that is relevant for the days ahead. As I continue my dive into Prometheus for monitoring, it occurred to me that I might be able…

  • Tech Tips – Upgrading your Argo cluster tools

    Moving my home lab to GitOps and ArgoCD has been, well, nearly invisible now. With the build pipelines I have in place, I’m able to work on my home projects without much thought to deploying changes to my clusters. My OCD, however, prevents me from running old versions. I really want to stay up-to-date when…

  • Creating a simple Nginx-based web server image

    One of the hardest parts of blogging is identifying topics. I sometimes struggle with identifying things that I have done that would be interesting or helpful to others. In trying to establish a “rule of thumb” for such decisions, I think things that I have done at least twice qualify as potential topics. As it…

  • Nginx Reverse proxy: A slash makes all the difference.

    I have been doing some work to build up some standard processes for Kubernetes. ArgoCD has become a big part of that, as it allows us to declaratively manage the state of our clusters. After recovering from a small blow-up in the home lab (post coming), I wanted to migrate my cluster tools to utilize…

  • Tech Tip – Azure DevOps Pipelines Newline handling

    Just a quick note: It would seem that somewhere between Friday, April 29, 2022 and Monday, May 2, 2022, Azure DevOps pipelines changed their handling of newlines in YAML literal blocks. The change caused our pipelines to stop executing with the following error: What caused it? Multi-line, inline block definitions.

  • The trip to Windows 11

    The past five weeks have been a blur. Spring soccer is in full swing, and my time at the keyboard has been limited to mostly work. A PC upgrade at work started a trickle-down upgrade, and with things starting to settle it’s probably worth a few notes. Swapping out the work laptop My old work…
