However, while taking the mouse to my required application, it often travels over the Places button, which automatically opens the places menu. I do not want this to happen.

How do I configure it so that a menu opens only when I click on it and not when I hover my m ...

After I upgraded to the latest Ubuntu 20.04. I noticed users that login via ssh (even for users just do port forwarding or system user e.g. gdm) have gvfsd & goa-daemon & all their related processes spawned in the background. Is there any way to disable that for non-GUI users login?

In Guake the first time I use it the window is not focused

When I first open Guake by pressing F12 anything I type does not appear, I need to click on the Guake window then I can type in it. From then on when I press F12 it is automatically focused.

I have "refocus on open" already ticked in preferences.

I also run Conky on login, would that have anything to do with it or might it be just a bug with Guake?

Motherboard problem: GRUB Rescue mode

I changed the hard drive with a new one already with Ubuntu inside (i'm sure of It).

I tried everything on the BIOS settings bun in any case It shows me the "GRUB, entering Rescue mode" screen.

So, my question is, if I change the motherboard (the current Is 7 years old) can i Solve this problem?

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.
