Display the image size when viewing image folder
in flag

I am using Ubuntu 20.04 and noticed that in the recent version of Files (nautilus) I cannot display the image size as an attribute when viewing a folder containing images.

Is there any way to display this information in this version? I found it useful and in some cases can speed things up.

I want the image size not the thumbnail. e.g. 640x480

I couldn't find anything on this. All the articles I found talk about running apps requiring root access or ju ...

I got a 512GB XPG NVME SSD and connected it via an SSD enclosure. When I was trying to set it up using GParted, I saw that there are already 3 partitions present.

Before trying to set it up using Ubuntu, I had plugged it into Windows to set it up but had failed to format it after allocating it successfully.

UEFI without secure boot
au flag

I'm not new to Ubuntu (have been running linux since the 90's) but now that I'll upgrade my computer to a new one again I'm wondering a bit about UEFI and Legacy boot.

On the whole, it seems that it is more 'modern' to run on UEFI than Legacy and that it will be phased out at some point later. So I'm thinking of switching to UEFI, but I do NOT want secure boot. I don't use dual boot though with W ...

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.
