Automatic network card configuration?
us flag

We have lots of different servers with different network cards, is there a way to have Ubuntu 20.04 automatically configure the network cards with DHCP? Right now we have to manually change the .yaml file everytime we install a new network card. It would be nice if Ubuntu could just recognize the new networks cards on bootup.

Here is more information, we have an Ubuntu 20.04 image which we inst ...

How to install OBS without Remote Control WebSocket component?
us flag

I want to install to test OBS but no the Remote Control WebSocket component.

I'm not using that component, and the fact that it exist means a listener/door opened, that I want to avoid (a simple password is not enough to make me feel safe).

What I like is never having that component installed, having it installed and disables would be my last option, but not my preferred one.

Is it possible?

Pretty new Linux user here. I have decided to split my hard drives in half and have added Ubuntu to one. First of all, I have a Netgear A6210 WiFi adapter. I have installed the A6210 .exe files downloaded to a flash drive. But I knew Linux couldn't open those files without installing wine to convert the files, I assume. When I do the command to "Sudo apt install wine" it tells me it can not be found. I  ...

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.
