From my Mac I can resolve local devices.

Touchpad is not working at all

I have an HP Pavilion Gaming Laptop 15-ec0xxx with Ubuntu 20.04, and its ETPS/2 Elantech Touchpad is not working

The touchpad shows up in xinput list, and so does my USB optical mouse, the ID of my mouse (9) is lower than that of the touchpad (12). I think this means that my mouse is registered before the touchpad.
Touchpad also shows up in /cat/proc/input/devices.

  • I can "see" external drives plugged into the imac in the Ubuntu 'Files' app.

Cannot disable key with xmodmap

My keyboard has a stuck end key (which is also numpad 1). I tried disabling it with the command:

xmodmap -e 'keycode 87 = '

I also tried:

xmodmap -e 'keycode 87 = 0x0000'

I checked xmodmap -pke and xev and keycode 87 is the correct one for this key.

After running these commands, the effects of the stuck key stop temporarily, but eventually come back.

For example pages scroll to the end, etc. Als ...

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.
