I just reinstalled my workstation to 20.04.3. In the past, I custom configured a couple of keyboard shortcuts that start with the Super key. I can add other keyboard shortcuts that include Super also but not any that start with Super. The one I'm missing the most is Super + n to start Nautilus. Now I can not add this anymore.

mounting and using a device with no partitions?

It has always been my understanding that to use a disk or other storage device, it needs to have a partition which can then be mounted and used. Is this wrong? I inserted an nvme device in the machine and using the 'disks' gui utility chose ext4 and successfully mounted it to /mnt/nvme. My current situation:

lsblk returns nvme0n1 259:0 0 465,8G 0 disk /mnt/nvme with no tree under it with 'nvme01n ...

How to install Android Virtual Emulator on Ubuntu 20.04.3. Not Genymotion or virtualbox

I just wanted to download an Android Emulator that isn't Genymotion or related with virtualbox. With EMULATOR being the keyword here, I don't want to download it as an OS. I just want like an app. For example: LDplayer. LDplayer is used to play android games on PC (Windows) But I want an alternate to this software so I can play android games on Linux. Thanks in advance.

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.
