No sound - Lubuntu 21.10
in flag

I used the Lubuntu 19.04, and the sound worked perfectly. I recently upgraded to Lubuntu 21.10 on a scratch install; unfortunately, no sound comes from the notebook's internal speakers, nor from the P2 connection for headphones.

I read some articles on the internet, but I couldn't solve the problem. When I access the PulseAudio volume control, I see that there is no sound output options, just wri ...

Docker containers can't resolve host on Ubuntu

I have installed Ubuntu server with the latest patches, and I switched to AT+T, and I suddenly was unable to resolve external sites from inside of a Docker container.

How to resolve this?

I noticed that AT+T switched to using ipv6 by default when I did a simple ping:

 $ ping debian.org

Purged package still choking the system

Some days ago I booted my dual-boot machine in Windows and, with my surprise, the fan was quieter.

Back to Linux I started investing what is going one, and it went out that was a process hogging all the CPUs' forces: Screenshot of the shell running top

The process was named postgres

I killed that process with sudo kill 6509

The fan slowed down and I thought that all was done.

Create a shortcut to a virtual enviroment
de flag

I have installed Spyder Python IDE in a virtual environment. For this purpose I used the following command:

python3 -m venv spyder-env
source spyder-env/bin/activate

I have to switch to the virtual environment and then type spyder. I am using Ubuntu 20.04. Can I create a bash command as a shortcut and then create a desktop icon to directly open it in order to save time?

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.
