What happens to a file in a sambashare hosted on Ubuntu when i access it in windows and configure it to be hidden?
cn flag

What happens to files in Samba share when the host is Ubuntu and the client is windows when I make the files "hidden" in windows?

I hide some files to make it look cleaner, but I don't want the actual files to be changed in any way, maybe there's a better way of doing it.

I have a customer that has a Ubuntu 20.04 VM running inside a qNAP NAS server providing information management functionality to windows 10 clients. The VM is joined to their domain but the qNAP server is not. The NAS server is only used as an easy place to run the VM. The VM is providing much more functionality than the NAS device can for this client, the details of which are a bit involved and would  ...

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.
