Problem

Solution

I searched on the Internet to solve this problem. I noticed that Colab will be disconnected if you don't click on the page. Here is an answer that I find:

function ClickConnect() {
  console.log('Working')

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

How to connect to Azure AKS Kubernetes worker node by SSH

Nodes are not assigned public IP. If you have accessible VM in the same VNET as worker nodes, then you can use that VM as jump host and connect the worker via private IP.

Alternatively public IP can be assigned to a worker node. This readme shows how to do that.

Steps how to attach public IP to a worker node

find out the resource group that AKS created for the node VMs

Open terminal and go to your project's lib folder. After that run the command below.
find . -name '*.dart' ! -name '*.g.dart' ! -name '*.freezed.dart' ! -name '*.gr.dart' ! -name '*.gen.dart' | xargs wc -l
