netplan: Why does it generate the back-end configuration at boot time and what is the consequence?
ly flag

This is because of the netplan key goal:

There are other posts here asking about a mysterious program called @!0,27;BDH. This program (is it a program?) appeared out of nowhere for me after I upgraded from 20.10 to 21.04 last Friday. I noticed it first when attempting to share my screen on a Zoom meeting with my friends. Upon sharing a screen on Zoom, you may choose to share your entire desktop screen or a specific application.

Ubuntu System Files Upgrading Process Issue
al flag

I use Ubuntu-Studio 20.04.2 LTS inside 2 desktop PCs and 1 laptop PC.

Each time there is an Ubuntu "core" files upgrading (linux-image-5.4.0-xx-lowlatency and others), the upgrading process tells me that the oldest files were erased.

But... It is not a reality.

If I use the command dpkg -l | grep linux-image-5.4.0-xx-lowlatency (where xx is the chronological oldest number of those files), I can clearly  ...

So i put in a second graphics card and when i start the VM now, the main graphics card gets passed through to the guest machine and the second GPU is just doing nothing apart from outputting some text on the screen(Something related to Disk Space) which u ...

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.
