How to fix brightness keys not working in Ubuntu 20.04 LTS
cn flag

I recently ran into a problem regarding my brightness control on my Lenovo Ideapad S145. The brightness keys are not working, and the slider in the top right corner is not working either.

A couple things worth mentioning:

I already tried the fixes where you edit the grub file. None of them worked. The brightness control works on the login screen, but doesn't work when I actually log in.

Automatic rotations are flipped when rotating left or right [20.04.3]
in flag

I've recently reinstalled Ubuntu on an old laptop to see if this issue was fixed in the latest version but it seems I'm still experiencing it. My laptop has a g sensor and when I turn it around it rotates the screen. I don't want to turn this off but whenever I rotate it to the left or right the screen is flipped 180 degrees from where it should normally be. A 180 turn flips the screen properly though.  ...

Can Nvidia Settings show "10bpc" (10-bit colour depth)?
gb flag

The picture below is found by Google Image search. On Windows, Nvidia settings show 10-bit colour depth for my monitor, but on Linux (installed the latest proprietary driver), Nvidia settings shows only up to 8bpc. My question is, does Nvidia + Linux support 10bpc in the first place? I mean, it would be pointless to try to figure out how to enable 10bpc, if it is not supported on Linux in the first plac ...

This is the error message:

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.
