GitHub Digest

When you use the advanced security features in GitHub, and in this case the static code analyser, you make use of CodeQL queries. These queries will scan for any potential vulnerabilities in your code base.

With the new community packs, you can add additional queries, like security checks, CVEs etc to your scanning needs. Read more to see how to apply these and what kind of value they already added to open source projects like Home Assistant.

Sometimes you need to do some cleaning and maintenance on your repository. Luckily there are some default tools in git to do so; the git maintenance will do the trick. Read on to learn how to apply this maintenance.

Yet another recap, this time no skyline, but a simple overview of your contributions. Simply enter your GitHub username and see the stats.

Coding Corner

Learn more about alert fatigue, SLOs and SLIs, and how to get better at on-call support by reading this article by Jamie Danielson of Honeycomb.

I have been using Postman for a while, and it has its good and bad points. There are a lot of alternatives (insomnia, Hopscotch, Nightingale etc), but I recently found this one: Bruno. A local version where the collection is stored in Git itself, which is a big plus for me. Check it out below.

Be aware that some domains where you can fetch the .NET installation files are changing due to a host that is going to stop. This will be an issue when you have CICD pipelines where you fetch the runtime/sdk from this location, or when running specific installation scripts.

So check the impact and act accordingly.

.NET Nook

I m more a hangfire fan, but Quartz is another great tool to schedule tasks in dotnet. Read the tutorial by Milan on how to use it in your projects.

We all know we should do testing, but testing with external systems is particularly tricky. So what if you need to connect to an OAuth server, but need to test all the different flows; not only success, but also timeouts, failures, throttling etc.

This means you will need to mock the http endpoint. Mark Oliver shows how this can be done to get full test coverage.
