I have a lab that contains the ACME domain which ACME-DC2 and ACME-DC3. It has a child domain called LAB with LAB-DC1. I made some infrastructure changes to my environment that broke Active Directory DNS for a while. Replication between my ACME domain to the LAB domain appears to be broken:

AWS - Adding multiple IPs to Security Group Inbound Rules
cz flag

I need to open 20 ports for 12 IP blocks.

Do I have to manually add 240 rules in this case? I feel like there must be a way to just copy&paste the IP list to somewhere.

I googled and found it's not possible, but it's hard to believe. https://forums.aws.amazon.com/thread.jspa?threadID=191133

Unbound stub files don't work?
ad flag

I have an Unbound server and an NSD server.

re1 -- Unbound for recursive DNS
ns1 -- NSD for Authoritative DNS

Both of these servers work. I can 100% use dig and get an Answer using both. The problem is - Unbound isn't passing authoritative requests over to the NSD server for my local domain. Below is my config. What might the issue be?

FreeDiskSpaceFailed: How to force re-check, instead of waiting for self-healing?
cn flag

I had FreeDiskSpaceFailed on one of my K8s nodes.

I fixed this by resizing the logical volume.

I don't want to wait until K8s has discovered that there is enough space now.

Is there a way to trigger K8s, so that the disk space gets checked again?

How to debug a website that appears to be unreachable to one person but not another (as a user, not the developer or admin)?

I have some website of a photographer that took some photos and is sharing them through his website. The website appears to work from one country (it works for one family member) but it does not even load for me.

The site does not use ssl so I suspect some local DNS issue to be the culprit.

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.
