The majority of documentation I' reading in internet tells me to use ssh-keygen and ssh-copy-id and other commands like these. I'm not doing this, because I have this same key in several hosts, and it woul ...

Ubuntu with Kernel 5.11.0-46 won't load/boot
in flag

This morning, I updated Ubuntu to use kernel 5.11.0-46 as recommended by the software updater. However, Ubuntu won't load after the update.

I am able to get to GRUB and select 5.11.0-44 as the kernel and get into Ubuntu but I'm not sure how I can address this issue long term. I tried changing the default kernel that GRUB uses as follows:

GRUB_DEFAULT=Ubuntu, with Linux 5.11.0-44-generic

How to send image from clipboard on Ubuntu to clipboard on Android using KDE Connect?

If I copy a text on my Ubuntu 20.04 then it instantly appears on my Samsung tablet's clipboard.

But if I copy an image to the clipboard on Ubuntu (using ctrl + shift + printscreen) then the image does not appear on my Samsung tablet's clipboard.

How can I do that?

When I log out, I can log in with gdm3 again but when the laptop goes into power saving mode the session usually crashes.

The installs are independent (different downloads, sticks, b ...

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.
