I need some help to troubleshoot sssd/krb5 error. Now i have Ubuntu 16.04 clients and want to upgrade it to 20.04. /etc/sssd/sssd.conf and /etc/krb5.conf are the same on both clients. All things work fine but login a user with expired password. Here some differences i found in /etc/sssd/krb5_child.log. krb5_child requests initial credentials a bit different way.

How do I change the audio output for one specific application?
ph flag

I want to change my audio output for Spotify by NOT changing the default settings to be able to hear music over my sound system and play everything else with my headset.

I already searched in the settings of Spotify as well as in the settings of my system but found noting. My system runs with 20.04.2 LTS and I just switched from Windows on Linux so everything should be up to date.

USB Input periferics not detected. How can I solve this problem?
eg flag

I'll be straight forward: I have a laptop (ASUS TUF GAMING FX-505DT) and it has 3 ports for USB-A in which I installed:

  1. Mouse
  2. USB HUB
  3. External SSD

The second port seems to work fine, but the problem appears only when I use more ports from the USB HUB. I need to install the Graphic Tablet, Microphone, Keyboard and one for Data Transfer (in total 4).

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.
