Problem with KDE plasma lot passphrase
cn flag

After installing Ubuntu 20.04 I decided to also install KDE plasma desktop. However, during the installation I was issued an SSH passphrase which I neglected to write down and now I cannot recover it. Is there a way to recover this passphrase or is my best bet to remove KDE and then reinstall?

Thank you

Using braces in rm in makefiles
in flag

So I'm learning about Makefiles and in an example, I was to remove files in the clean part. I wanted to do something along the lines of rm paper.{aux,pdf,bib,bbl}, but when I did make clean it didn't recognize any files like that. Doing that remove command outside of the makefile works just fine. Do makefiles not play nice with braces like this? I didn't find much about braces in makefiles in cont ...

How to enable missing/hidden ethernet network interface?

I put my laptop to sleep. When I came back my ethernet network interface is just gone. No internet so I had to use wifi to post this.

ip link show produces 1: lo 2: wlp.. (wifi)

Ethernet is just GONE. This happens from time to time. If I reboot, ethernet is back. But the interface name (e.g., enx806d97218e00) changes at every boot. It is a PAIN that the interface name does not stay the same acros ...

Screen Glitches (random lines) ubuntu 18.04
th flag

My Ubuntu 18.04 machine has random lines (horizontal usually) on it after waking up. All I have to do to get rid most of them is to reboot. Are there any other solutions to this problem? Some apps such as chrome, or Spotify are always broken with these kinds of lines all over and they flicked back and forth between the app and a black box on my screen and a restart won't help either. I'm thinking it's a ...

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.
