The edges of the display are cut off. I looked at a few of the other responses, but my TV doesn't have those settings for the display (I have an element TV). I wouldn't really mind not seeing the full edges but it cuts off the time display and I can't tell the time.

I accidentally messed up the permissions by typing sudo chown -R root:root /usr. It was supposed to usr instead of /usr. anyway, I lost sudo function and showed the error message sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set. But I followed this thread https://askubuntu.com/a/471503/1127900 and solved that issue.

I have a dual boot laptop, and the isssue is very similar to this post 6 years ago, but all my options are different and when I try to use the answer it doesn't work.

Remote Dual Booting

I manage an IT lab of 37 computers with dual booting (Dell Optiplex with Windows 10 LTSC and Ubuntu 20.04 LTS on separate drives). If Wake-On LAN from another PC: default boot via Grub is Windows, Ubuntu needs on-site presence. Is there a way to remotely select a desired OS to boot? Either the PC is powered off, or a reboot on any of the two systems is needed. Many thanks, Alex

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.
