rsync (ubuntu 20.04) to Synology DS218 option -a doesnot preserve user name and group of files

I have been on the internet searching for my problem. I use rsync to copy files from my ubuntu 20.04 desktop to NAS Synology DS218+. It worked fine with ubuntu 18.04.

I was able to reproduce the error manually on the terminal, so that makes it easy to tell you the problem. Normally my backup runs in the background via a cron job.

All other shortcuts seem to work fine.

I upgraded my workstation (AMD threadripper + NVidia RTX 3080) from Ubuntu 20.04 to 21.04 with do-release-upgrade.

After the upgrade when I logged in, there was a popup message saying "screen lock requires gnome display manager". Furthermore, all the icons on my desktop were duplicated, e.g. two recycling bin icons, with one non-functional.

The worst thing though, is that it's now randomly freezi ...

How to sync clipboard in KDE Connect/Android 11?

The very first feature listed on this app is:

Shared clipboard: copy and paste between your devices.

In Android 10, Google broke that feature and now the phone can receive clipboard contents from the desktop but not send them to the desktop. The developer appears to have a workaround as the release notes for 1.14 say:

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.
