I have Gnome Tweaks installed on Ubuntu, and I was curious if it is possible to assign font colors and styles to Gedit and Terminal through the system theme to create a more unified look.

As I workaround, I was able to select Solarized in both apps, but the backgrounds didn't match the Arc-Dark theme. So in Gnome Terminal I had to customize the background and manually enter the hex code used for  ...

Something has gone wrong even if the upgrade was successfully

There are tons of questions about this error but almost all of them refer to interrupted dist-upgrades. Instead, I've upgraded from 20.04 to 21.10 without any problem (at least, no popups that show errors).

The machine is headless and it's configured with a dummy monitor to be accessed by a remote desktop application:

What should I do if my laptop is slow and also gets hot?
jp flag

I'm new using ubuntu 20.04. I had windows 10. Now that I changed I notice that my laptop gets hot, not too much, but it does. Also I feel like when I browse through the web it is slower than it was when I had windows 10. I've seen that there are a lot of options to try. ¿Is there something that everybody should fix when using ubuntu 20.04 for the first time that I am not doing?

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.
