I want to set up a Raspberry Pi wireless AP. I downloaded the Ubuntu image for Raspberry Pi (server), wrote the image to a microSD card, then put it into my Pi 3B+. Ubuntu boots up just fine, so far so good, except...

How to change the default program which opens a file type (for example a .png file) within Wine?

How do I sign public and private keys for installing a driver?

I am trying to use a Huion H640P graphics tablet to use with my machine that has Ubuntu 21.04 installed.

Surprisingly, the tablet works without any driver installation with Kubuntu 20.04.02 LTS, but the laptop does not even recognize the device in the Ubuntu 21.04 machine.

Anyway, I was looking into the unofficial drivers here, as suggested here, in the Huion Support.

WWAN - NetworkManager doesn't take over addresses from ModemManager

However NetworkManager doesn't seem to receive those and finaly fails with a timeout. I don't have a clue how to further debug this issue.

My system is Kubuntu 20.04.

USB harddisk gets two different mount points - why?

Running Ubuntu 18.04.5 LTS on arm architecture (Odroid-N2+)

I have connected a USB harddisk (/dev/sda) to my computer with a 4TB ext4 partition (/dev/sa1) and have edited /etc/fstab to have /dev/sda1 mounted at startup to let's say /media/user/placeA. This works, but /dev/sda1 is also mounted to /media/usb0 (there is nothing for this in /etc/fstab) which I don't need and don't want.

Basically I currently have one HDD where on different partitions I have windows and Ubuntu installed and my dual boot is working perfectly.

But I just bought a SSD and I am planning to move my windows and associated partition to the SSD leaving Ubuntu on HDD.

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.
