How can I get Ubuntu to stop notifying me of updates?
in flag

How can I get Ubuntu to stop asking me to update my system? I've tried two things in its configurations, dconf-editor and in the "Software & Updates", and clearly neither has worked. enter image description here

Quicklists don't work for specific applications
hk flag

I use Unity launcher Quicklists for libreoffice and some other applications, mostly to open certain commonly consulted files. This works fine. However, for evince and gnome-terminal, none of my quicklists show up: I just get the option to unlock the application from the launcher or launch it.

For reference, here's what I have to try to test evince.desktop:

Google Meet extremely slow likely due to Hardware Acceleration
mx flag

Every time I enable Hardware Acceleration in order to have visual effects on Google Meet the entire browser (Firefox, Chrome, and Brave) is so slow it's impossible to use.

I've tried installing the latest NVIDIA drivers (nvidia-driver-470), but that didn't help.

What can be done to ensure the browser isn't crawling while hardware acceleration is enabled?

Sound input - only offering Analog input- Built in audio - NO SOUND

I am trying to explain it as simple as possible bcs I don't know much about computers. My microphone doesn't work apparently. This is what I see. Everywhere else I see I should be able to see also the microphone, but no. This Analog input does not catch any sound. Ofc. the laptop has a built-in microphone. I have updated my software to the newest one available.

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.
