How to do hover to focus AND allow keyboard switching via ctrl tab etc?
in flag

You use gnome tweaks to turn on hover to focus. But then you can not also use keyboard shortcuts to change between windows AND type in the other windows. You have to then use the mouse to hover over the window you changed to using the keyboard.

Trying to resize my Ubuntu partition (dual boot with Windows) but Gparted gives a scary warning because the unallocated space is to the left?

I am currently dual-booting Windows 10 and Ubuntu 22.04. I wanted more space on the Ubuntu side so I used Windows disk management tool to shrink that partition and that left me with 100+ GB of unallocated space.

MOTD: '444 updates can be applied immediately'. `apt list --upgradable` lists just 4!

I have a Ubuntu 18.04.6 LTS machine that says to me, after logging in:

444 updates can be applied immediately.

To see these additional updates run: apt list --upgradable

But when I use apt list --upgradable, as suggested, it lists just 4 available updates.

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.
