as said above aspect ratio is stuck at 4:3 after i boot "normally". But whenever i boot into safemode, 5.8.0.25-generic kernel, and then proceed to "normal boot" from there, all of a sudden it's fixed.

Also, previous to this i had a kernel panic, where VFS (i think, don't remember exactly) was out of sink. Now that i brought upon myself, as i tried to download gcc-11 and didn't input the correct  ...

How to automatically find the 'freshest' PPA for a given package?
cn flag

Exact use case:

  • I've potentially found a bug in a program (specifically i3-gaps).
  • As I don't have the latest version installed the maintainer asked that I install the latest version to check if bug is still there.
  • I've originally installed the tool from a PPA. Checking this PPA, there is no version more recent there. Only version is quite outdated.
  • So I'm looking for other PPAs. I found this page:

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.
