Avoid switching between two versions of python for each service in the same environment
in flag

I managed to install python 3.6 alongside python 3.10, the problem is that when 3.6 is selected in update alternatives, walinuxagent service works fine when while netbox, netbox-rq and nginx services doesn't; the opposite happening when 3.10 is selected.

A workaround is selecting each python version depending on which service I want to start. Is there a way to avoiding doing this every time?

Cannot add space from deleted Windows partition

I recently found that 50 GB was simply not enough for Ubuntu and deleted the entire Windows partition to assign the space to Ubuntu. I can't resize the Ubuntu partition and it does not go over 50 GB (the original size). I have tried to reallocate it from a live Ubuntu disk, but there are still no changes.

Now I am stuck with 135 GB of unallocated space.

How can we manually install zoteros libre office plugin on linux ubuntu22.04 if we installed it via Software Center?

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.
