Frozen app? Stuck spinner/Dolphin icon on the task bar

Kubuntu 21.04, Plasma 5.21.4

I've got a blinking Dolphin icon on my task bar. It looks like it's starting-dying-starting-dying, however KSysGuard System Monitor doesn't show anything. I can open Dolphin, really open it - and it gets its own icon on the task bar and works fine. If I use the "Kill A Window" option, it kills the task bar as well. How do I identity the process causing it, and shut it ...

Should I update from 18:04 LTS Ubuntu Server to 20.04.3 LTS?

Presence of id_dsa file prevents ssh-copy-id from working

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.
