It is getting annoying. Is my bottleneck simply a lack of memory? Can i do anything else other than upgrading my ram? This is what my system p ...

I wrote 3 simple lines, this opens a new terminal and executes the following code.

import os        
os.system("gnome-terminal -x airodump-ng wlan0mon")

But when I press ctrl + c, the new terminal instantly closes. I don't want the terminal to close. Is there a way to do it?

Grub2 option in a Dell xps 13 9310 with ubuntu 20.04
cn flag

According to Dell's indications, there must be a partition on my computer with a possibility to diagnose the system through Grub2. But when I do the test with the F12 Grub button it does not appear and it takes me to the BIOS where there is no such option.

I do not know what to do to be able to have that option. Can someone give me some help?

Thanks

Just curious - is it normal after doing an apt-get update then upgrade to repeatedly receive messages telling me to install ubuntu base on my desktop computer?

Reading about what ubuntu base is makes me wonder why do I need it on an operating system?

I wish to mount SMB share on a common mount point for all users and auto mount it when it's accessed, like when you map a network drive to a common drive letter in a Windows environment and it just uses the user's login credentials for authentication.

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.
