How do I resize a partition running Ubuntu in a VM?
br flag

I'm rephrasing the question here because there are others that answer the question of how to resize an active partition, but perhaps this will help someone running a VM.

I set up a 20.04 VM under Fusion and started compiling something, which failed because it ran out of disk space.

So after resizing the virtual storage of the VM in Fusion, I restarted Ubuntu and went into Disks to expand the root vo ...

Usability problem, End User perspective:

Having opened an PDF in evince Document Viewer (Ubuntu 20.04 LTS), how to close via UI?

Issues when using two screens with different DPI scaling on 21.10

I have a laptop with a 4k display, running at 200% scaling. When connecting an external 4k screen without scaling (ie. 100%), things don't work very well. If I move a window from the laptop to the external screen, it maintains the 200% scaling, and vice versa. That's not what I want - the external display is double the size of the laptop screen, and therefore I want to maintain the scaling as set up for ...

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.
