Sleep mode prevents Shutdown -h. Is there a workaround?
in flag

I like using shutdown -h. It lets me leave my computer knowing that it'll turn off. However, if I leave it for so long that sleep mode kicks in, the scheduled shutdown gets ignored. Is there any way to make shutdown -h's shutdown trigger during sleep?

The output does not mention ESM. I activated my UA subscription on this machine, and the output is still the same. What does it mean?

(1) X-Y packages currently do not receive updates. If so, how can this be fixed?

My ubuntu does not boot in graphic mode: after I pass the grub, a black screen is displayed. The only way I found to go to graphic mode is to activate non-graphical mode with Ctrl+Alt+F2, and then re-switch to graphical mode with Ctrl+Alt+F1. Otherwise ubuntu get stuck with a black screen and  ...

Edit: Thanks for the response. This looks like a do-able fix to the problem. But the question remains: Why? Apparently, I'm not the only one struck by this error. How/Why does it happen?

On my Bionic Beaver (x86-64) system, I noticed today that I could not install anything (with "apt install"). Further, when I do "apt-get update", it returns immediately. Upon investigation, I found that my  ...

I am trying to use an old laptop as a gateway from wired lan to a wifi internet hotspot:

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.
