Has anyone else seen this behavior and, perhaps more importantly, found a fix? I get the same result if I right-click on the panel and select "Dash to Panel Settings" as when I click  ...

sa flag

I'm very green with Linux/Ubuntu in general so please forgive me.

I'm trying to setup a shared network folder so I can copy over files from my Windows PC without needing to use a physical drive. I used Samba to create a shared directory and was able to link to it on my PC. I made sure all the permissions were correct for the shared folder. The problem now is I can only add files to the shared dir ...

No sound after laptop lid closed
in flag

I used to have the problem where my HP laptop wouldn't wake up after the lid had been closed but I've just upgraded to 21.10 and that issue is sorted, however when I open the lid now I have no sound whatsoever! The only way I know to get it back is to restart the laptop which is exactly what I had to do with the wake-up problem.

Any ideas?

Ubuntu 18.04 Display brightness not working - Unknown Display in settings

I have a new ThinkPad E15 Gen 3 link to Lenovo's website that I purchased less than a month ago. I installed Ubuntu 18.04 on it and the installation went smoothly.

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.
