VPN/WIreguard forward traffic internally as well as externally
br flag

This may be more of a Linux firewall question, but the context is the Wireguard VPN setup on Ubuntu. Note, I'm barely getting acquainted with a lot of this stuff.

I have Wireguard up and running on Digital Ocean Ubuntu with Windows and Android clients using it. All seems good.

The basic firewall commands I use when it comes up is/are below: So, the 3rd line appears to route all traffic coming in on  ...

Is there any image viewer that supports animated SVG?
lu flag

I know we can view animated SVG files using web browsers. I wonder if there is a software that works exclusively as an image viewer with SVG animations support.

How to make Ubuntu forget my GitHub credentials?
ke flag

A group of friends are going to develop some software.

I have suggested using a VM (Ubuntu) to guarantee that we all have same toolchain, versions of libraries & packages installed, etc.

I will set it up and then share it.

As the last step before sharing, how do I make Ubuntu forget my GitHub credentials, so that they will each have to enter theirs the first time they fire up the VM?

xfce4, xfce4-appmenu-plugin takes a lot of CPU
us flag

I am on Ubuntu with XFCE. I installed xfce4-appmenu-plugin. My cooler is quite active from this time, so I checked what is going on and I was surprised by this.

enter image description here

Should this plugin really take a lot of CPU as in this example? Or is there some problem on my side?

My laptop configuration.

AMD Ryzen 5 4500U with Radeon Graphic, 16GB RAM

Thank you.

Bluetooth switch does nothing
ru flag

When I oped the bluetooth page of the settings, the bluetooth switch is off and the page states "Turn on to connect devices". When I turn the switch to on, simply nothing on the page changes, yet the switch stays on.

Due to this it is impossible to look for or connect devices.

I am using Ubuntu 20.10 with a 5.13.0 kernel.

alternative ways to access a Ubuntu server
tr flag

I had spun up a Ubuntu EC2 (the 20.* Ubuntu AMI) on AWS, in a private subnet and a specific VPC. To SSH into I was using a Bastion host (kept in a public subnet) Had installed nodeJS and hosted a React application on this Ubuntu (which I maintain). All was working fine. And the web application is still working on port 5000.

Use tablet as Input [USB/HDMI or Bluetooth]

I recently bought a tablet that runs Android and it has USB-C and HDMI. I would like to use it as a graphic tablet, connected to my laptop, which runs Ubuntu 20. I often use softwares as Inkscape or GIMP, and I would like to display them on my tablet and work on them on it.

I already tried with Weylus, but, since it is working via Wi-Fi connection, there is an annoying lag that makes it really hard ...

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.
