How to fix conflict with another program in xbindkeys?
in flag

I'm trying bind alt+tab to mouse button 7 but it keeps giving me an error

*** Warning ***
Please verify that there is not another program running
which captures one of the keys captured by xbindkeys.
It seems that there is a conflict, and xbindkeys can't
grab all the keys defined in its configuration file.

This is what I have

SSH Over VBox NAT NOT Working Ubuntu 20.04 Host (desktop) Ubuntu 20.04 server (guest)
tr flag

I can get internet on guest by setting vbox adapter 1 to bridged network adapter

and host-guest communication works when I set adapter 2 as a host-only adapter

This is sufficient if I don't want to use a firewall, but I do... with this solution I need to constantly fiddle with UFW to allow adapter 1 communication.

After some reading, I realized that I should be able to set up adapter 1 as a nat adapt ...

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.
