I recently updated to Ubuntu 20.04.3 (kernel 5.11.0-34-generic #36~20.04.1-Ubuntu SMP), so this may be a bug. After a few hours of use the shared memory partition fills up. According to df, partition /dev/shm has 16G of data in it:

Lets take CVE-2021-3448 as an example.

It's easy to see when the deb package got the backported fix, and what package is installed on the server.

Different background for each workspace
cn flag

In the past, setting the different backgrounds for each desktop was rather an easy thing to do.

I have not tried that for the past 2 years, and now I have been struggling for a few days to find a way to do it.

What is the "modern" way to set a different background for each workspace? Ubuntu 20.04 is in question.

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.
