cn flag

Let's say I have a directory at which there are all sorts of video and image files. There are MP4, AVI, MOV etc. files and there are PNG, JPG, GIF etc. files all mixed together. Is there a browser that would enable a user to switch easily between views of that directory such that only the video files or only the image files are visible? It's a little like the search functionality of Nautilus, where a se ...

Ubuntu 21.04. How do I check an rsync backup set?
in flag

I’ve been using Timeshift and have about 200+ snapshots (190GB) in my Timeshift backup set. What are the commands to check this backup set? I want to make sure the backup set is not corrupted.

Restic has the commands ‘check’, ‘prune’ and ‘cleanup’. What are the similar commands for rsync? I checked an rsync command list page and didn’t find anything relevant.

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.
