I was wondering how can a user in a group access a file made by a different user
cn flag

For example, I made a file in my directory in a useracc and set the permissions as only groups can read that file How can the user in that group get access to the file I made in my useracc and read that file? For ex: I made a file foo.txt in user bob is part of blue group and alice is part of red group , I want the file to appear in alice account since I set group permissions that groups can read.

I am having issues with my brightness since my first install - I can’t change it, they're stuck on high mode.

kernel modules restricted on a system with secure boot disabled
pl flag

I have a system with EFI BIOS but without Secure Boot, but system refuses to load third party modules (vmware modules) with the "unsigned module loading is restricted; see man kernel_lockdown.7" error. If "mokutil" executed the response is: "This system doesn't support Secure Boot"

What's happening? Not having Secure Boot implies kernel modules don't need be signed. Even worse, "/var/lib/shim-sig ...

How to adjust the default volume size after installation of Ubuntu 18.04

I installed Ubuntu 18.04 on VMWare recently. When I create the VM, I specify the disk as 1000GB. I go through the installation by all options kept default except I selected the docker package. After installation, the file system is only 200GB. How to let my main file system take a major portion of the 1000GB of the virtual disk rather than only 200GB?

I recently installed Kubuntu 20.04 on a new Razer Blade 15 (mid-2021) with built-in audio card Realtek ALC298. Everything has been working pretty well audio-wise, with PulseAudio working perfectly fine.

Enroll Mok after driver change
cn flag

So I change my driver (Nvidia 470) to Nvidia 460. It asked me to define a password for Mok.

Upon restating I choose continue to boot instead of enroll Mok. Now I want to revert to 470 and the same scenario appeared. This time I choose to enroll in Mok and placed the password. Will my Nvidia driver be loaded correctly or do I need to do something else?

Best regards

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.
