I changed some files and cannot use GUI in ubuntu 20.04
kr flag

I was trying to restore previous versions of the files and this is what I did from root: cp -r /snap/gnome-3-34-1804/66/usr/lib/x86_64-linux-gnu /usr/lib

From that moment I cannot use the GUI. I can only login to the computer through the terminal (for example tty2). Please is there any way to repair the GUI?

I have Ubuntu Mate 18.04 32-bit running on an old Medion E1210 netbook. I set the power management to go to sleep mode after 1 hour of idle time when connectet to the power grid. But what I get: when the computer is idle, it will take much longer than 1 hour until it goes to sleep mode - on the other hand, when it's executing some heavyload tasks it will go to sleep mode after some time even when those  ...

Certain applications cannot be reordered in Dash to panel
cn flag

I use the Dash-to-Panel extension (see for example https://askubuntu.com/a/1052673/800252) to get a Windows-like toolbar. This should allow either grouping or ungrouping multiple instances of an application and if ungrouped it should allow rearranging their order (after checking that Lock taskbar is off). For the most part this works perfectly. However, for at least one application (Mathematica) diffe ...

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.
