Realtek ALC4080 Microphone not working
in flag

I'm using the same setup with Windows, and there it works perfectly fine, but on ubuntu it doesn't work. Sound from the headset is there, but microphone does not take any sound. Also in Microsoft Teams it seems it is confused to the point, that it thinks that output is input, and threats output as microphone. Please, if you can, help me with that.

Is adding a PPA safe?
cn flag
A J

Are all PPAs safe? From where do I know which PPA refers to which packages? Can adding a PPA cause any harm? Or is it that the package when downloaded will cause harm? In particular is it safe to add ppa:ubuntu-toolchain-r/test? Or is it more safer to install packages from official websites?

How can I change the default mouse cursor position to center screen?
cn flag

I would like the login and startup default position of the mouse cursor to be the center of the screen.

Every time I log in and when Ubuntu 20.04 (64 bit) starts up, the mouse cursor's default position is the lower right hand corner of the screen. This is driving me crazy.

Do I need to make a startup script that runs with xdotool?

Please advise.

Thanks, Chris

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.
