I'm freshly switched from Win10 to Ubunutu 20.04 and this is my first time using Linux for an extended period of time. Please forgive me for obvious beginner mistakes.

I can't indent my file indentation
jp flag

I write C file on Emacs and I'm using 4 tab width for my files. In Emacs, I see that my file is indented with 4 tab-width. But when I try to read my file with cat command, I see that my file is indented with 8 tab-width.

First, I thought it is because of Emacs, then opened file with Gedit and re-indented file from 8 tab-width to 4 tab-width and saved it. But still, when I read my file from termin ...

Recently I have installed Ubuntu 21.04. Soon after the installment I found out that the Wifi is not working after sometime. The available network list is continously loading and there are no networks on display. Even if I toggle the wifi from the settings to on and off it is not working. Only after a restart it starts working.

Simplescan doesn't start/load
in flag

Ubuntu 18.04

I pressed the Windows key, type Simplescan, see the icon come up and it's selected, and press enter. The mouse icon turns into the "loading" icon (a circle) but then nothing happens after that.

I also tried disconnecting my scanner and repeating the procedure. But, that results in the same thing.

The scanner that I have installed is Brother ADS-1200

So I am trying to find a way to remove the batt ...

Can you please let me know why MariaDB has not released a Mariadb 10.2 official repository for ubuntu 20.04? Does that mean that we cannot install Mariadb 10.2 on Ubuntu 20.04? MariaDB 10.2 and Ubuntu 20.04, are they incompatible?

Is that okay if I install MariaDB 10.2 on ubuntu 20.04 from the following official repository?

Are Windows viruses recognized by AppArmor or SELinux?

I know windows and Linux are completely different environments but are there developers that implement the recognition of windows viruses in AppArmor or SELinux?

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.
