How to change resolution?
in flag

I recently created a bootable live usb to use ubuntu for a specific lesson in uni. I did it with Rufus, installed the following version "ubuntu-22.04.2-desktop-amd64" and once everything was set and done I checked it out. I restarted my laptop and opened it with Ubuntu. I chose the "Try Ubuntu" instead of installing, but I noticed that my resolution was set too low. I went to change it, however it's set ...

I am on HP EB 1030 x360 20.04 and works good with the exception of intel ax211 WiFi which gives all kinds of jitter problems.

Move boot SSD from BIOS motherboard to UEFI motherboard?
cn flag

I'm (still) running 18.04 on a old BIOS-based motherboard.

Back in the day when all motherboards were BIOS-based, upgrading was as simple as moving a HDD from one system to another. Is it still that simple when doing a to-UEFI migration? (The current boot process probably uses UUID, but I'm not sure; computer just died: after 6-7 seconds, it powers back down.)

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.
