Why is Ubuntu server 20.04 with vm.swappiness = 0 still swapping where are plenty of free memory?
cn flag

Background

We're running several KVM servers on Ubuntu 16.04 and have started testing the upgrade to 20.04. What we found is that even though we've never seen any swap usage on our 16.04 servers, after a couple of days, a 20.04 server will show a few hundred MB of swap usage. It's not a big problem as vmstat show very little swap activity, and munin graphs confirms that swap in/out is insignificant, ...

Is there a debian package for the python module PyGLM?
us flag

I am trying to build a software in Launchpad, but I get the error

ModuleNotFoundError: No module named 'glm'

I found https://pypi.org/project/PyGLM/ but I could not find any package titled python3-pyglm in https://packages.ubuntu.com/.

Is this package available under some other name? Note that installing from pip is not an option while building in Launchpad.

I generated the OpenPGP key on my Windows computer. I don't know why I didn't do it on Ubuntu. How do I get the key from that computer onto Ubuntu? Do I need to generate a new key?

New HP laptop Unable to use Ubuntu 20.04, 21.04
us flag

I am a long time Ubuntu user and recently purchased an HP Pavilion laptop. When using Live Boot, both 20.04 and 21.04 give bizarre resolution and the display is hard to read due to insanely magnified UI.

I decided to install 20.04 and tried doing so. But it resulted in GRUB only coming before Windows 10 (pre installed ) and no Ubuntu even though I successfully installed it from the Live session.

/usr/libexec/evolution-calendar-factory does a significant up/download every time I boot?
th flag

Without fail, on every boot, this process starts, does some network traffic (25Kbps up and 5 down) for about 5 minutes, then exits.

I'm not sure what it is doing, which I guess is the main concern. I'm not comfortable with getting comfortable watching any process doing a big network transfer every time I boot? It appears to be an essential component of gn ...

Lost desktop Icons Ubuntu 20.04

Is there a specific reason why I would lose an APT desktop icon on Ubuntu 20.04 - After boot today, Clementine was still on the desktop but with no icon. I fixed it by deleting that desktop item and merely added it back, but why did it drop off in the first place? - this has somewhat happened before with clementine where the "fruit" icon changes to a white icon with a gear in it, ie, prior to the "allow ...

How to reset file permissions to default in ubuntu 20.04 system

While working in eclipse I realised that my pom.xml file had read-only permissions. In order to change that I ran

sudo chmod +rwx '/home/babi-b/eclipse-workspace/TodoApp' 

To change permissions in the entire directory (TodoApp) where the file is found. However, permissions of the entire system has been changed to read-only.

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.
