Timeshift backup on btrfs partition fails with error when @home subvolume is included in backup
sr flag

I installed Kubuntu 21.10 on btrfs partition. By default, it creates @ and @home. I booted into my new Kubuntu btrfs installation, and indeed, I am able to make a Timeshift snapshot, just as "advertised". However, when I try to include @home in the snapshot, I get this error:

Only Ubuntu-type layouts with @ and @home subvolumes are supported

This puzzles me, because this is exactly the layout I have.

Ubuntu Studio 21.10 Freezing, Requires Hard Reset
cn flag

I can't seem to figure out the exact cause of the freezing. It seems to happen most often during video playback (Hulu, Netflix) in fullscreen mode and during gameplay through steam, but it's also frozen during normal web browsing and just moving around in the file manager and terminal. The screen will freeze and the last second or two of audio will loop. The keyboard is unresponsive but I can sometimes  ...

I found this article Unable to install wine32 due to broken packages but this is not quite the end of the story for me.

After digging down the dependency trees it seems that the underlying cause were older gcc-11 installation on the predecessor 18.04 holding essentials libraries.

The following packages have unmet dependencies:

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.
