New installation of 20.04.2 and ZFS installed via Cockpit. I've setup SMB shares and have managed to get TimeMachine working.

The problem is when I want to copy/paste while on the Mac (Big Sur) to an SMB share on the ZFS volume. Anything under 16GB is great. The network hits 2.3Gb (2.5Gb cards), all great. Anything over 16.x GB in size and the copy process just hangs once it's transferred about 1 ...

On a 4th generation X1 Carbon laptop, which generally runs Linux and Ubuntu really well, and which has been updated every six months, I am currently having hard locking issues on the default Ubuntu Gnome UI (Edit: my bad, I presume it is no longer called Unity these days but Ubuntu's Gnome variant and theming) of Ubuntu 21.04 "Hirsute".

This is an i5 with the usual Intel graphics baked in, I can p ...

Ubuntu 21.04/GNOME/Mutter -- no right click menu for launcher/icon options?
in flag

If there's one thing that keeps on bugging me with GNOME on Ubuntu Desktop (21.04 at the moment, this was already in a few previous versions as well) is the lack of getting properties of an icon (and possibly remove it, modify it, etc) with a right-click menu option.

Example: every so often one ends up with this example situation where you have a "ghost" of another install, which in some cases ha ...

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.
