unknown display ubuntu 21.04
mx flag

ubuntu 21.04 won't recognize my monitor, neither it lets me change the display resolution. I tried sudo ubuntu-drivers autoinstall but it doesn't seem to work (it fixed it to the correct resolution tho). And probably as a result of this, the hdmi often gives no signal when i run ubuntu.

Does dist-upgrade replace service files?
my flag

I recently noticed a server performing apt-get update && apt-get dist-upgrade

Amongst other things, docker was updated and restarted.

However, I noticed some changes I made to the service file previously were now gone. The file at /lib/systemd/system/docker.service seems to have been reset.

Is this possible? I don't recall if I ran daemon-reload after these changes.

EDIT: To be clear: I'm ...

Something along the lines of Wanda the Fish
cn flag

So, I've been thinking about creating a bash version of a fortune teller on the model of Wanda, but with different figures. I mean: a script that makes you write down your question of the day. The response-quote is given by a character randomly extracted from a set of, let's say, 6 fellows. I'm planning to match like 20 quotes with each character, whose features can be found in a small manual that brief ...

My system is a ThinkPad T14 (Gen. 1) with AMD Ryzen 7 Pro 4750u (which has an integrated Renoir GPU). OS is Ubuntu 21.04 with Kernel 5.11.

It was working properly until yesterday when, out of nowhere, it did not want to re-boot nor shutdown. There was no reaction to sudo shutdown -h now nor sudo reboot nor when I used the commands from the GUI. So I forcefully powered it down by holding the power but ...

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.
