As browser security improves, many applications have implemented CORS headers to protect against unauthorized access. I’m working on a Chrome extension that needs to check if a certain URL is present on GitHub, before it opens the URL in a new tab. Let’s explore what we can do.
We’re currently in the business of moving from Mesos/Marathon to Kubernetes. As we have a microservices environment we can move service by service. We have multiple clusters running, so I need to track which teams have which services (still) running on Mesos/Marathon.
Let’s see if we can lift the data out of the system using the Marathon API, JQ and cURL.
At Wehkamp, we use the Hubot Grafana project to make our Grafana dashboard available in Slack. It mainly helps our standby team to make quick assessments on what’s going on with our website. Last year, we saw we could not upgrade the package from 2.5.2 to 3.0.1, because slugs could not be used anymore. But we use slugs and… quite heavily! So we did not upgrade our Grafana v7… until we got hit by the input field bug. We decided to see what we could do to bring our slug feature back to our ChatOps bot!
Anneke Keller (CTO), Koen Roumen (Head of Platfom) and me did a talk on DevOpsDays Eindhoven 2022: A true story on how we learned how to handle the immense web traffic caused by a successful influencer campaign. How we built a platform with Karpenter and Keda for rapid and massive auto-scaling and the effects this had on our platform.
When working on the bot-zero-sharp project, we had the need to decouple the request handler and the creation of the chatbot. We like our request handlers to be automatically detected and added to our pipeline. In this article we’ll discuss how we use background services to create a chatbot that uses dependency injection.
When working on the bot-zero-sharp project, the need arose for better handling of enums decorated with a [Flag] attribute. In a previous article we explored how to use Handlebars.NET to generate JSON strings. In this article we’ll build further on that generator to add support for enums. We will also move away from the static JsonHandlebarsDotNet to an injectable version.
