v4l2loopback module failing on Ubuntu 20.04
ph flag

I am trying a new web camera on a workstation that hitherto had no video capture devices attached. It should be plug-and-play but none of the programmes is able to find the camera once connected.

First I checked whether the kernel itself was identifying the camera:

$ lsusb

So there is a camera, it must be a software thing. Che ...

I just installed Ubuntu and I got the error "executing grub-install /dev/sda failed this is a fatal error" but Ubuntu works fine. Should I worry?
id flag

I had Windows 10 installed on my computer and I began installing Ubuntu alongside Windows. Everything seemed to be going okay until I got the error. Afterward, it told me to restart and I did, and Ubuntu seems to be working fine. Does that mean that my Ubuntu OS was installed okay? Do I need to fix my installation of GRUB, or is this an error message I can safely ignore?

As the title says I borked an upgrade. It paused for a moment to ask me something about gnome settings, and I pressed "D" for details, and then ctrl+c to try and get out of the output it gave.

Now I cannot open a terminal, nor can I shutdown through the GUI. Firefox is working fin though obviously. Alt+F2 also works, or at least the command window pops up

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.
