Ubuntu 18.04 Microphone recognized but not working
us flag

I tried both headset and webcam and both microphones aren't working so I am confident the issue isn't the mic itself.

I looked up the setting and they are recognized as inputs. I also tried disabling one and running the other and nothing worked.

I also tried other solutions I found online (without really understanding tbh...) like running "sudo alsa force-reload" and "modprobe snd_usb_audio".

Name USB devices to help identifying them

When I connect USB devices such as mp3 player or bike computer, they mount right away but are given names like "46A1-4000" & "6132-6635"

When I have several devices connected it gets very confusing to know which is which, especially when they have inbuilt memory & removable SD. 3 or 4 drives show with random numbers & no way to easily know what is what.

I'd like a way to name these such  ...

Do I need to refresh my Ubuntu laptop by pressing F5 as I do on Windows?
cn flag

I am using Ubuntu 20.04. My curious mind wants to know if I need to refresh my Ubuntu PC as I do on Windows after turning my PC on. By "refresh" I mean if I need to do something similar to pressing F5 or right-clicking and then clicking the Refresh button on Windows.

If yes, how do I do that? And if not, why?

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.
