Unexplained port blocking

I'm having an issue with Ubuntu 21.04, where I'm unable to access ports that are behind Port Fowarding/DNAT on my router.

I have a working port forward on my router from (Public IP):443 to 192.168.2.223:4443

I know that this works, because I have an older system that when I plug back in and configure with 192.168.2.223, I can jump on to https://(Public IP) using an external jumpbox and I can see a w ...

The keyboard shortcut Ctrl + Alt + PrtScn + o worked on Ubuntu 20.04, but it doesn't work with my current installation of Ubuntu 21.10, gnome: 40.4. This keyboard shortcut should shut down the computer instead of pressing the hardware power button for 4 seconds if necessary.

The title is my theory of what happened, but I'm not certain: I installed Ubuntu alongside Windows 10, but while I am now able to boot Ubuntu without any issue, I am not longer able to boot Windows 10.

When selecting a boot in the BIOS settings, I do see the Windows 10 boot, in addition to the Ubuntu boot.

enter image description here

But when I select Windows 10, the following screen displays "Prepa ...

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.
