How to find a device based on its device ID
th flag

Recently I had a problem that one of the USB ports was stopping Ubuntu 20.04 from suspending. It was suspending, but in a split of the second started again.

I found in several posts (1, 2, 3) that it is possible to fix this by disabling a device in /proc/acpi/wakeup, but how to find which device stands behind each device code was not mentioned.

Recently, my Ubuntu vm got corrupted and so I thought it was time to start fresh (was needed anyway). Started a new vm, reinstalled everything and it was great, everything was working again. However, one thing that isn't working anymore is my vpn setup.

The great part though, is that I still have the old vm (just not turned on), so if I need to, I can start that vm and look at the old setup.

I can't ...

Preconfiguring ssh password for server installer

I am trying to install Ubuntu Server on a device on which the available HDMI port broke down, so I can't connect a display whatsoever.

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.
