I want to use timeshift to make backups. But I only see it make backup for /usr, /var. So I want to know whether it will make backup for /boot, /etc,...

If I broke the files under /etc, will the timeshift be able to help me fix it?

Also I remember there was a time I use timeshift to restore files, and when I reboot I found there are two "grub", not knowing why.

Can someone explain my Questions? I'm a ...

Disposition of xserver-xorg-hwe-18.04 in system upgraded to 20.04
us flag

I've been upgrading some 18.04 systems to 20.04 and in general it's going well. But some of the systems have a package xserver-xorg-hwe-18.04 still installed after the upgrade. My thought was to replace it with xserver-xorg-hwe-20.04 but there doesn't seem to be such a package.

So...I don't know what to do with this package. Is just removing it safe (according to synaptic it has no dependants)?  ...

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.
