I am using Ubuntu 22.04.1 LTS, I installed mutillidae and it worked perfectly, but now I wanted to install DVWA and it also worked, but when I entered mutillidae again I got this error: " The database server at 127.0.0.1 appears to be offline. "

I tried to change the DVWA port to another and it didn't work. Is it possible to have these two pentesting labs on the same machine?

How to change the settings in 22.04 of a known Wifi network you're not connected to?

Opening the Wi-Fi settings there is a list of networks, but it's only possible to edit the settings of the network you're connected to.

IMHO that is a major (GNOME) regression from 20.04

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.
