us flag

I'm looking to add a new drive to an existing NAS server, and would appreciate a second look at my plan before I pull the trigger. Part of the challenge is the new disk will be added to an existing RAID, which itself is encrypted, and also makes up a physical-volume in an existing volume-group.

Current Setup:

There is a single logical-volume ('media') and volume-group ('raid') made up of two physi ...

Surface book 2 webcam supported (in 2021)?
in flag

I'm new to Ubuntu. I tried using a virtual machine using VirtualBox to run Ubuntu on my windows10 surface book 2. When I try to use my webcam, I get an error that it cannot be found.

Are there working drivers for the surfacebook 2 webcam? Seems like, according to this question, in 2019 this wasn't supported.

Does this mean that there's no way to get the webcam working in Ubuntu?

How to fetch email in the background?

I use GNOME Evolution as my email and calendar client. It only sends email notifications and event reminders while Evolution is running.

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.
