How does Direct Rendering not make a chaos?
ng flag

With Direct Rendering each application is allowed to render itself. But how does this not cause chaos if each application can render itself whenever and wherever it wants? Shouldn't there be some centralized mechanism for rendering? I know that with X it is the only one that can touch the frame buffer but how does Direct Rendering work then?

Can someone explain this in simple terms?

Critical differences between Ubuntu Server and Ubuntu Desktop for 20.04 LTS?
in flag

What are the actual meaningful differences between Ubuntu Server and Ubuntu Desktop, particularly for 20.04? I know people say among other things that Desktop has GUI by default and Server has text, and Desktop has end-user apps that Server doesn't, but these differences don't really matter as Desktop can be installed and configured to be the same way -- e.g. "systemctl set-default multi-user.target" an ...

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.
