I have two latops, on each of them I have a user without encrypted home folder. I wanted to encrypt the home folders of these users so I followed this tutorial.

Running Ubuntu 20.10 on a Macbook Air 2011. When bluetooth paired a pair Razor Anzu smartglasses I noticed that something is wrong with how bluetooth i configured.

How can I retrieve my compromised personal information in Ubuntu Studio?
ng flag

I had a major system failure a few days ago and I'm desperately trying to retrieve my Hard Disk data without compromising the entire system. I've performed an fsck command on the /dev/sda2 partition but this will no longer work. I don't have access currently to my backups. I left my swap space in good standing but the computer's laptop, fan, and potentially the hard disk might be dead. Part of the criti ...

Does "Erase disk and install Ubuntu" option delete/erase everything on the Hard-drive?
cn flag

I'm just confused. I was a Windows user pretty much all my life. But now I want to switch to Linux for good. I have a 1 TB hard-drive attached to my laptop. As you know, in windows, the total hard-drive storage is divided into a couple of drives(i.e. Drive:C, Drive:D, Drive:E etc.). Usually, Windows is stored in Drive:C. My question is if I choose the Erase disk and install Ubuntu/ubuntu-derivatives op ...

6 times high pitch double beeps after login to Ubuntu 21.04 on Dell XPS 9750
st flag

After I login to Ubuntu 21.04 it plays six times a double high pitch beep sound from the speaker. So it's not on boot, it's after I logged in. There is no error message popping up. First I assumed that this must be a DELL error beep, but it should come while booting the system, not after login. I've ran the DELL diagnostic, but it doesn't find any error. I also realized that sometimes it's not loading t ...

My Ethernet isn't working. Let's try and resolve that.

Alright so, I installed a fresh copy of Ubuntu so I have nothing from apt-get installed (so no net-tools, etc.)

I have no other computers around me apart from my M1 MacBook Pro and (of course) my Ubuntu PC, running Ubuntu 20.04.2 LTS.

why `ls -d .` does not list all dirs, as `ls -d */` does?

Like it says in the heading, I don't get why the "correct" usage of ls -d should add */ in order for ls to find the directories in my current dir, where adding the trivial . isn't helpful

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.
