Black Bar/Distortion that follows cursor

Whenever my mouse is moved, a small black bar (only a few pixels tall) spanning from the left edge of the screen to wherever my mouse is will spawn in and then disappear. This happens about every second my mouse is moving. There are also (sometimes) similarly slim but long lines of what looks to be almost distorted pixels whenever there is a decent amount of movement on the screen. I'm using a Dell Insp ...

Create an Ubuntu server on Ubuntu desktop

Apologies if this is a basic question, but is it possible to use my Ubuntu 20.04 desktop to create an Ubuntu server "on the side"?

I am relying on AWS EC2 at the moment, and it is starting to cost me.

This could be some kind of Ubuntu VM that has ports opened (I suppose but again, Ubuntu nb), but I am more thinking of some regular server creation on my desktop.

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.
