how can i remove one of multiple ubuntu partitions on a windows 10 dual boot UEFI laptop
ye flag

I can find plenty of info on totally removing Ubuntu from dual boot, but I just want to remove one of three. I can select Windows or one of the other two and they boot up just fine. I would like to remove the (partition deleted) one from the menu. Thank You in advance.

Ubuntu 20.04 stop/start/reload network stack with netplan
us flag

I have looked at all the solutions about how to stop/start/reload the network stack when using netplan configurations (without installing NetworkManager or nmcli) and none of them seem to give a complete option of how to restart the network stack.

I tried:

sudo systemctl stop networking; sudo systemctl start networking sudo systemctl restart networking

sudo systemctl restart sytemd-networking

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.
