Running a docker swarm cluster with 3 nodes where only 2 are workers.

All DNS names of the services are pointed towards the Node A. The problem was discovered because when using a registry repo one of the nodes would never fetch the images. When I checked it, I found that no matter what is done everything running from the Node A cli (like a curl to the Repo URL) gets a connection refused. We test ...

How to restrict Dovecot's passwd userdb driver to only mail users
th flag

I am using Dovecot's passwd userdb driver, like this.

userdb {
    driver = passwd
}

This works fine, but it seems to allow all users in /etc/passwd to receive mail, including root, which I do not want. Is there any way to restrict this to only users belonging in the mail group, or do I need to use another driver?

Why does Duplicity allow a new symmetric passphrase on incremental backups?
in flag

I am new to Duplicity and trying to test it as a new backup tool. However, I have found that it permits incremental backups with new symmetric passphrases which then causes the backup to be unrecoverable. For instance, this is my test script:

#!/bin/bash

PASSPHRASE=one duplicity full /home/ken/scripts file:///home/ken/tmp/
read -p "Press [Enter] key to start incremental backup..."

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.
