When I'm logging into the server there are some welcome stats that say: Memory usage: 65%.

When I run free -m I get:

Is it possible to force ALSA / pavucontrol to not let auto microphone gain be changed by video conference systems (Zoom, Google Meets,...)
at flag

i am on an Ubuntu 20.04 and my USB microphone works like a charm. Since one of the last updates Google Meets is automatically setting the Gain of the microphone to 100%, which leads to a very "crust metal band" sound (that is what my colleagues told me ;)). In many video conference systems is an option to switch off the automatic adjustion of the microphone gain. Unhappily in Google Meets there is no su ...

I have a folder with files 1.JPG, 2.JPG, ..., 12.JPG

Is there an expression to process all the files at once? I want to use a JHead command, but I think there is a general solution.

Bluetooth headset codecs in Ubuntu 18.04 vs 20.04

I know that Ubuntu (PulseAudio) has well-known issues with Bluetooth Headsets and for some time I was struggling to fix this. After different attempts this one helped me and everything seems to be working. I even managed to make auto-switch profiles work when I use a microphone.

But I use two Ubuntu systems (18.04 and 20.04) and available codecs differ for the same headphones on both systems. Even though  ...

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.
