Th reason I am asking is that listing the package names is of little help since there is not a one package - one font logic. Sometimes it's one font family, sometimes it's a random collection.

In addition, the package description often ...

In my case that service is Tor. System log (journalctl -k|grep -i tor) shows that the kernel is killing the service (or its parts?) due to OOM.

So i wanted to automatically restart tor?

Hide certain toolbar icons on the side of KDE Plasma's task manager?
in flag

[I FOUND IT OUT MYSELF, ANSWERED]

I want to hide certain toolbar icons, like NoMachine, Bluetooth (the icon in blue, next to Discord), Most Recent Device, etc. The icons are taking up most of my task manager and I tend to use a bunch of space on the left with pinned and open programs, like terminal and wine. Is there a way? I am using regular Ubuntu, but with the KDE Plasma desktop. Thanks!

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.
