When working on Bash scripts, it is often useful to make them more flexible by using parameters. In a previous blog post, I demonstrated how to add named parameters to a single script. However, if you want to apply this feature to multiple script files, it might make sense to move the code to a […]

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!

I’m using Prettier to reformat my code in VSCode. When I start new TypeScript projects, I need to add a .prettierrc file. Let’s see what it contains.

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 a 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.

I ❤️ Handlebars! So I was very very very happy to see that Handlebars was ported to .NET! It is a mega flexible templating engine as it can easily be extended. I’m currently working on a project where a I need to parse objects via JSON templates to JSON strings. This blog will show how to instruct Handlebars to parse into JSON and add some nice error messages if your template fails.

Let’s connect some Ikea TRÅDFRI bulbs to your KAKU ICS-2000. Adding them is not so easy, as the manuals just did not work.

At Wehkamp we ❤️ Slack! Seriously, in order to improve our efficiency, we’ve connected many of our applications, alerts and dashboards to Slack channels. But, as with all things, there is a right way and a wrong way of integrating a webhook at enterprise level.

Let’s explore how easy it is to create an application.

Chris Vahl (Cloud Engineer) and me did a talk on Full Stack Live #2 (Orange Talent: At Wehkamp we did a very successful influencer campaign, but it didn’t go well for our website. In this session we discuss what happened and how we mitigated our problems. We also show how we want to move forward using Kubernetes, Karpenter and Keda, to create a platform that scales better. This session is in Dutch.

Let’s use a small snippet to convert any article to Markdown. This might come in handy if you want to repost your articles to blogs that support Markdown like DEV.
