Angular: jQuery events not firing

On a web application we were building I had a strange issue. A jQuery widget was working as expected until I also tried to use it inside an Angular application. The widget that was responsible to expand or collapse a panel, refused to work. Clicking on the panel header had no effect anymore.

This was one of those situations where the solution is obvious afterwards, but I had no clue at first what was going on Verwarde emoticon.

When looking inside the widget, I found code similar to this:

Nothing wrong with that code you should say! Unless you realize that this code is only executed when the DOM is ready. The HTML views that are loaded by Angular are loaded afterwards when the document ready already fired. So the initialization logic for the widget is not executed for new elements loaded by Angular.

To fix it, I updated the widget to use the (newer) jQuery event delegation syntax:

So simple, once you know it…

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...
