add www or http to domain on apache
in flag

Requests for example.com work fine, but www or http://www do not resolve. I am using anycast dns from domain provider. I am not certain this is a apache issue. Should I add an A record @www.example.com pointing to server ip? Or is there a redirect issue on the server itself. I am a beginner level technician.

Rename using both captured groups and other variables
ws flag

In this question I understood that we can only refer to captured groups in the rename command using single quotes.

Is there a way to use both captured groups and other variables in the same rename command?

Example:

var="-old_file"
cd /etc
rename 's/(bash\.bashrc)/$1$var/' *

Factorial scaling on laptop makes external display a bit blurry

I have ASUS ROG Zephyrus G14 laptop with Ubuntu 20.04, it has 2K screen so I set scaling to 150%, but when I connect my external Dell display without scaling its content is blurry.

When I switch "Factorial scaling" off Dell shows good and crisp picture.

It feels like "Factorial scaling" option is switched on for both screens and changes the way how things get rendered.

  • create a tmux session
  • mount the file system in the tmux session
  • cd into the home directory
  • execute some script that will run for a long time

How might one remove old Linux kernels by manually deleting files and directories *on a mounted system drive*?
cn flag

I have a machine that isn't booting (even into GRUB). I suspect that it is not booting because of a lack of hard drive space in some partitions. I have the hard drive of this machine mounted using a USB live distribution. How would I manually delete files and directories such that older kernels are removed?

Problem with libc6 and libc6-amd64 while attempting to upgrade to libc6 2.34

So the core of the problem started after Ubuntu prompted me to upgrade. I am on Ubuntu 18.04.5 (Bionic Beaver). After the upgrade, I tried starting my browser to no avail. So I navigated to the binary in a terminal, ran it, and got this error:

Applications in fullscreen mode overlaps any other window

Kubuntu 21.04. For example, if I put my web browser in full-screen with F11 I cannot show any other window in front of the fullscreen app. It's like the fullscreen app doesn't detect where is the focus. It's like the fullscreen app is above all other windows. How can I change this behavior?enter image description here

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.
