How to set a company's Windows based PC settings into an Ubuntu PC
cn flag

I need to install Ubuntu 18.04 alongside Windows 10 but when I do that our IT cannot set administrative settings for Ubuntu like Windows because they don't know anything about Linux. So, I cannot connect internet with Ubuntu. So is there any way to set Ubuntu user and device names same as Windows so the internet provider of our company's server will not see any difference. For example;

Nslookup suddenly won't resolve against Cloudflare
in flag

As of Friday afternoon Australian time, I'm getting failures using nslookup with 1.1.1.1. It works fine with 8.8.8.8, and Powershell Resolve-DnsName works fine. nslookup without specifying a server works fine, where the local DNS uses 1.1.1.1. I've tried this on a variety of Windows flavours, with a variety of ISPs and router devices.

For example:

Use hostname/domain instead of IP for A-record
id flag

I need to create a A-Record for a subdomain on server X to make it point to server Y, but the IP from server Y is changing from time to time.

Server Y also has a hostname / domain.

The A-record does just accept IPV4 Addresses.

Is there also a way to use the hostname / domain of server Y instead of the IP address somehow, or do I have to change the A-Record each day by hand?

Ubuntu DNS not working after installing a Bind Container
cn flag

I have an Ubuntu 20.04.3 LTS (GNU/Linux 5.4.0-109-generic x86_64) server with Docker installed. I created a Bind9 container however it would fail to start. Turned out this was because the resolver service on Ubuntu was running and taking control of port 53.

So I killed the resolver service and then the Bind9 container would start.

Problem I have now is that Ubuntu host O\S won't resolve any DNS na ...

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.
