Firefox shows duplicate window options after installing Unite gnome extension on ubnutu 20.04
de flag

I really liked how we used to have the window action icons on the top bar back in ubuntu 16.04. Now to get the similar top bar feel on Ubuntu 20.04, I installed Unite Gnome Extension. This used to give me almost the same look and feel but for some reason it is not working properly on Firefox 90.0.2 and is showing the window options separate to the top bar (refer to the image below).

Snap automatically disabled on reboot
tr flag

I have noticed it quite often, though not every time that whenever I restart my ubuntu 20.04 machine, for around 5-10 minutes, one of my snap(till now I have experienced this issue only with "brave" and "rambox") would not show up in the dash, nor in the applications menu, nowhere. I executed the snap list command and found that when the system restarts, it is shown that particular snap is disabled.

I have noticed that I can cd into this location, but this seems to mirror the correct direc ...

I am facing two issues which I think they might be related:

  1. I need to shutdown because if I reboot, then the wifi adapter does never connect to the modem. It simply spins for like 60 seconds and then a pop up message says "I am not connected to the network".

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.
