How to disable audio of only one HDMI / Displayport port?
ua flag

I have two monitors connected via Displayport to different ports of the same GPU. I want to permanently disable audio of one monitor, and keep audio in the other one.

Pavucontrol is very useful at disabling hardware entirely (i.e. the webcam's mic). But I cannot find a way to disable audio from Monitor 2 while keeping Monitor 1 intact.

I'm happy with PulseAudio's hot swapping and it works great when ...

Create a Systemd service in Ubuntu to run MKDocs
ye flag

I am running a server with MKDocs for documentation.

In order to use the MKDocs from the directory where the project is you need to run mkdocs serve -a 192.168.3.107:8080 in order to get it to start.

So far I was using /usr/bin/tmux new-session -d -s "MKDOCS" "cd /root/mkdocs && mkdocs serve -a 192.168.3.107:8080" to have it run in the background but this is a very sketchy solution and I would l ...

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.
