HDMI monitor stops working when lap top lid is closed
tv flag

I have an HDMI monitor attached to my Ubuntu laptop and I usually work with my laptop lid closed.

For some reason suddenly the setup stopped working.

Now when I close the lid the external monitor screen goes black like there's no signal, but the system is not suspending nor hibernating because when I open the lid everything starts from where I left off (no login screen).

Ubuntu keeps auto adjusting its microphone input volume regardless of the app I am using
us flag

Whenever I am building my project on Android Studio, for some reason the microphone volume goes to 100 without notifying me, and when I next join a call with somebody, they get annoyed because of my input volume.

Also, if I am using some audio recording tool like vocaroo.com, speaking too loud lowers the volume as well, which is very annoying.

It happens in other scenarios as well, whenever somethin ...

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.
