I'm on Ubuntu 20.04, and my computer has a webcam that has been faulty for a while. On sleep/suspend, I've been seeing a lot of usb 1-8: device descriptor read/8, error -71 errors. I've looked into dmesg output, and it appears that the camera is constantly disconnecting/reconnecting. This is what the dmesg output looks like:

resize root partition from rescue mode

I mean to resize my root partition. I am currently not able to boot from a Live CD or Live USB. I know I can keep trying to tackle that problem.

Alternatively, I wanted to know if, booting from my Ubuntu in recovery mode, dropping to a root prompt, using parted to resize, is expected to give me a resized, bootable partition.

I know it is a risky operation, I am not asking about that, and there is ce ...

How to output stereo sound on multiple channels of a surround output?

My computer has 4 sound output jacks, that are meant to be used as 7.1 surround output. However, I only ever have stereo sound to play. I would like to connect speakers to one jack and headphones to another one, and have the same stereo sound output to both at the same time. That way, I can simply turn/put on whichever I want to use.

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.
