Prime profile settings issue: Which one should I choose from the below prime profiles for software development purposes?
az flag

There are three options in Prime Profiles:

  1. NVIDIA (Performance Mode),
  2. NVIDIA On-Demand,
  3. Intel (Power-saving mode).

The Ubuntu 20.04 battery is draining too fast. If I choose Intel(Power-saving mode), the NVIDIA graphics will function or not. If it will not work, then it may be affected for Machine Learning related projects.

But the new issue I'm facing is frustrating.

After installing the Brother scanner driver (brscan4-0.4.10-1.amd64.deb) for an MFC-J690DW, I could use the scanner with Simple Scan (Document Scanner) in single page mode but not with the ADF (Automatic Document Feeder).

Recently I have an issue where I have to use a tty to change permissions of my home directory back to my primary user and this happens at every boot. I have no idea what is causing this to not be persistent. How do I get to the bottom of this and avoid this annoying workaround in future?

Order of operations in tty:

login with UN & PW

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.
