How do you disable all Super key shortcuts in Gnome?
om flag

I would like to use the Super key as a modifier for keyboard and mouse shortcuts in other applications. However, Gnome seems to have dozens of keybinds that are tied to that key and that appears to affect its usability as a modifier in some apps (notably, I can't use it as a modifier in IntelliJ). I've removed the ones I could find in Settings, but there are a couple I can't find defined anywhere:

Ubuntu mount CIFS share(smb1) and shared via samba

I have two pieces of shop equipment that are sharing with smb v1. The equipment is too expensive to replace to upgrade to smb2-3. My solution is to put them on an isolated subnet with a Linux server mounting the cifs shares, then sharing with smb v2. I am experiencing permissions issues and can't figure out where I have messed up.

How to disable comment highlighting in vim?

I find myself on a new Ubuntu 22.04 machine running Vim 8.2, and I've found that all comments (in all languages) are highlighted, and it's driving me crazy.

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.
