How to make a domain name resolve to the same IP address as another domain name?
ni flag

I have a AWS ELB to the gateway of an internal service.

I have some other host names that I need to be resolved to the same address as the ELB DNS name.

In my current set up, I'm using /etc/hosts to manually point the names to the IP address of the ELB.

But the IP of the ELB changes once in a while and I'll have to update /etc/hosts again and again.

Is it possible to just tell my operating system to ...

Multiple PXE server separate from DHCP

I work in an enterprise environment. We have many locations, each with many subnets, and both Linux and Windows everywhere. DHCP servers are centrally located for everything (Or rather, we have 2 each handling half the scope's IPs).

Now I want to get prepared for a fullblown recovery in all locations. So basically I want the DHCP servers to stay in place, but I want multiple PXE servers to be que ...

Problems related to ip requests related to translation services in the internal network
ru flag

Our team is planning to use translation services and OCR services on the internal intranet network.

So I opened the firewall for ip communicating with translate.googleapis.com and vision.googleapis.com.

But since then, we have been unable to proceed because of a firewall in the 'oath' related url. What should we do in this case?

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.
