how do you set the /etc/resolve.conf domain on hirsute server?
cn flag

I used to be able to address my old server at "dckr1.local", I setup a new hirsute server and change the /etc/hosts lien to read:

127.0.0.1 dckr1.local dckr1

and added to /etc/resolv.conf

search local
domain local

but can't get it for the life of me to work when I reboot. resolve.conf gets overwritten. Not sure if by something in systemd or something it's calling like cloud.init.

Ubuntu fresh install + vino = blank screen

Can I make snap to preload packages (pycharm) on boot?
lc flag

Some packages, like Intellij's PyCharm, etc. take an insanely long time to start for the first time. I found this question which is about the same problem, but asked wrongly, it seems.

Basically, what I would like is snap to perform the "first start" of the snap app for me in the background as the OS boots / I log in so that I wouldn't have to wait literally minutes for the app to start.

Or is there  ...

This is from https://help.ubuntu.com/community/LiveCDCustomizationFromScratch.
Here I'm supposed to do inside the chroot environment,

How to rsync my Google Drive with a local folder?
in flag

Since the built-in nautilus Google Drive is so super slow, I was wondering if there is a way to have my Google Drive contents automatically downloaded to a local folder and then when I make a change it would automatically sync?

Basically, I would like to create a /home/user/Google-Drive where to sync my existing Google Drive. So that all my Drive files would be locally on my machine.

Is there a way to toggle the Thinkpad Privacy Guard in Ubuntu 20.04?
cn flag

I have a Thinkpad T480s which comes with a Display obfuscation called privacy guard. I read that this is supported since kernel 5.4. I have Ubuntu 20.04 with 5.4.0-74-generic.

But when I check it:

$ cat /proc/acpi/ibm/lcdshadow
status:         not supported

I wonder if there is also a hotkey predefined to toggle it on or of?

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.
