Various resources I found about debugging hibernation mostly cover the wake-up or complete failure to suspend but  ...

How to make Ubuntu ask for a password every time a user tries to access system settings?

I need this specifically for the wifi settings, so that no one can change, turn on, or off wifi on my machine without putting the root password in the prompt.

This morning I awoke to my PC unable to login.

At first, I wondered if I'd run something in DOSBox that had corrupted the disk... After finding out that was likely not the case, by using recovery console to SMART check and fsck my disks; I set about setting up proprietary EFI compatible memtest86. Nothing wrong with RAM either. I'm running a 2015 HP z640 server.

Snap Store app?
pl flag

I have Snapd installed, it's working and I can access the store on the website, but is there any option to create an app on my desktop for the store, please?

I tried Linux Mint first where I could install Snap Store and have an icon right there on my desktop, but installing Snap Store from the website on my Ubuntu platform doesn't give me any kind of shortcut for it.

Is there a way, please?

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.
