Update caused network icon to disappear and wifi connection lost - How can I debug this?
cn flag

The updates window popped up and I agreed to update the computer. After the upgrade it prompted me to restart my computer so I did. When I logged back in to my user I notice I have no internet. And the network icon is missing from the top right corner.

How can I fix this? I guess the update disabled my network adapter somehow, and the network manager is crashing on boot or something because of it ...

Ubuntu 18.04 and 20.04

Hi,

I have a backup script running as a systemd service (borgmatic) with the use of systemd-inhibit to block the user to reboot/sleep/shutdown the computer. This works well.

Unfortunatelly, when the user tries to shutdown or reboot the computer in GNOME and nothing happens - i.e. the action silently fails - then the user is confused and eventually turns off the computer by lo ...

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.
