accounts-daemon do I need it?
us flag

I am only asking cause I see it pop up in htop on a server. I am curious, will it break my server to uninstall it? As I would like to know if it has anything to do with login passwords or even ssh-keys. Does accounts-daemon have security risk? Will uninstalling it fix this risk?

Ubuntu 20.04 only get sound but no picture for mkv files
br flag
Kaz

I recently installed Ubuntu 20.04 on a new SSD drive now all mkv files only playback with sound and no picture on both the video player and vlc. I have installed the ubuntu-restricted-extras which has not resolved the issue.

I was running Ubuntu 20.04 before changing the SSD and I had no issues with playing mkv files.

Any suggestions/advice would be greatly appreciated.

Thanks

The screen simply glitches every second or so.

How to reinstall missing libraries to repair ubuntu 20.10 after stupidly purging some libraries and shutting down

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.
