The Ubuntu 22.04.x version of libpam is not working correctly for me. It does not allow user authentication with an active directory. I have installed the package in its latest version, downloading the source code and compiling it and it works perfectly.

The version of libpam-radius-auth package that comes in Ubuntu 22.04.x is 2.0.0-1, while the latest one is 2.0.1 and this one works fine.

gpg-agent is older than us: how to find "us"?

From what I understand, the gpg-agent is older than us warning happens when the gpg-agent version doesn't match the gpg version, often because there are two gpg-agents installed (and sharing the socket). Other answers I saw about this warning usually boil down to uninstalling the old gpg-agent or restarting it after an update.

I have set up an ovs bridge in order to take advantage of libvirt's virtual network with vlan support. As recommended, the host network interface is configured on an ovs port, rather than directly on the bridge. The host nic receives tagged and untagged traffic.

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.
