How to restart Kubernetes running on Ubuntu LTS 20.04.3

So I have installed Ubuntu LTS 20.04.3 on four raspberry pi 4b's computers. Then I made one the master/control plane node, and 3 worker nodes (upon installing kubernetes). It is all running great and I can also run Docker images and containers, etc. I am trying to find out the proper way to shutdown the kubernetes cluster for maintenance and then restart it, without losing all my K8S configuration.

Blurry/Pixelated fonts after changing screen's scaling size to 125% on ubuntu wayland

I wanted to play wine games that only worked in Wayland so I started a new session and when I set the resolution to 125% I ended up with some completely disgusting text fonts that didn't look like nothing at all if you will allow me. If there is anyone who could help me with my problem I sincerely thank him.

I am a long time Ubuntu user who regularly updates my OS after a new release has been available for a while. I recently updated this laptop to 21.10, having installed incrementally from 16.10 when it was brand new.

During an idle moment I looked at the directory system under the system profiler and was surprised to see so many mount points for Snap, all with "100.00% (0.0 Byte(s) of XXX MB) and a ...

One app for two OS
cn flag

I have just installed Ubuntu Studio 20.04 alongside with regular Ubuntu 20.04 and I’m wondering if it’s possible to use installed on first Ubuntu apps on the second Ubuntu without reinstalling (so it won't use much space and maybe use one folder to save documents). Searched but found nothing. Is there any way?

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
