Installing Debian drivers in Ubuntu 20.04

I have Nvidia driver 460.80 installed on my Ubuntu 20.04 desktop. I've bought myself a RTX 3080 Ti and now my Ubuntu wouldn't boot (I can only go into recovery console). 3080 Ti requires Nvidia driver version 460.84, which isn't officially available via Ubuntu yet but I've found a .deb for it. So before I do anything stupid, can I install a Debian driver on Ubuntu?

Monitoring Mouse and Keyboard Usage
us flag

I am looking for an application to monitor keyboard and mouse usage on Ubuntu.

Keyboard usage could be defined as the difference between the first key press and the last key press. The last key press is when a key is pushed followed by a period of inactivity (e.g. 1 minute of non-usage). Total keyboard usage is therefore the sum of each duration of keyboard usage.

Mouse usage is similarly defined to ...

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.
