First of all, I recognise these are not the most recent versions of duply and duplicity. The client runs servers on various OS versions, and we currently install duply and duplicity from the system repositories. I've searched and can find no indication that this is an issue fixed in a more recent version. If someone can show me that it is, we'll update the systems to install updated versions of these pa ...

dnf list available updates for locked packages

With yum versionlock status I can get a list of available updates that are currently blocked by versionlock. With dnf this command doesn't seem to work. I cannot find a dnf command that does the same. Is there perhaps another way?

Since dnf does not have a command like dnf versionlock status, I have created a small script to do sort of the same.

Native Authentication with Apache

Reading the CIS Benchmark documentation, I saw that a good practice is to disable mod_auth_basic and mod_auth_digest.

Does Apache have some native way to perform authentication that is more modern than these?

Using socat to proxy abstract-namespace UNIX sockets across network namespaces

I have a system service that listens for commands on a UNIX domain socket in the abstract namespace. I now need to access this from a process in another network namespace. Because the socket is in the abstract namespace, it is network-namespace-specific.

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.
