Ubuntu Studio only shows 1 window at a time
cn flag

Recently, I installed the Synaptics DisplayLink driver in Studio so I could use a docking station with a second monitor. However, whether a second monitor is connected or not, only 1 window will display at a time. For example if I have a browser open and then fire up a terminal session, the  ...

Allowing a sudo command to run without needing password
us flag

I have the following command:

sudo service cron start

When I type it into the terminal, it asks me for a password, just as it should. But I need for users (or if all users aren't possible, then at least my user) to be able to run this specific command without needing to put in any passwords. I googled around, even looked at similar questions here and found about visudo, so I gave it a try, and put thi ...

Where can I find the layout maps for the variety of options when working with "Layout of numeric keypad?"
au flag

I set up my keyboard to have a "compose" key on my Ubuntu 21.04 system. I love the flexibility! When exploring (System Settings-Hardware-Input Devices-Keyboard-Advanced), I discovered the Layout of numeric keypad selection. There are options there like ATM/phone-style, Hexadecimal, Unicode additions, etc.

I am very interested in both the Hexadecimal and the Unicode additions... However, I have ...

What are some disadvantages of ubuntu GUI?
us flag

Based on my personal experience GUI uses more computer memory (as the aim is to make it for user friendly and not resource optimized). As a result it can be slow, GUI becomes more complex if you need to communicate with the computer directly. What are some disadvantages of ubuntu GUI? can we have an official ubuntu CLI release?

I've been having this problem for a long time. After following a step-by-step guide on how to install Ubuntu on VirtualBox (and please don't tell me this is a VirtualBox topic because VirtualBox cannot help with this issue), but as soon as I finish everything, instead of getting the login screen, I get this little terminal thingy asking me to enter my "ubuntu login", and when I do, it asks for my passwo ...

I also tried to use hwe mode, but I still have the same problem.

I cannot manually install the driver after the server is installed, because compiling from the source requires several packages that should be installed during the installation when the network is availiable. ...

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.
