Transmission port closed when using VPN
ls flag

I am using Transmission for torrenting. I noticed that when the VPN is connected the port is listed (in Edit/Preferences/Network) as closed, but when the VPN is not connected it is open. Torrenting sometimes works like this, but I would like to understand what is happening and whether it can be improved. Ubuntu 20.04 Thanks

How do I replicate Ubuntu desktop file share mounting in Ubuntu server?

I'm running a piece of software called hpool, it's related to Chia crypto farming. It is temperamental and somehow locks files in place that other crypto farming software needs. On windows I believe it does this with the exclusive use functionality. I had to run it last and keep the required shares as read/write access for that reason.

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.
