How do I recover my files using backups in Ubuntu 22.04?
gu flag

I reinstalled Ubuntu 22.04 and then made a new profile and whatnot. Of course I wanted my files back, so I decided to run backups.

I have searched but I have literally no idea how to use backups to restore files, especially in a different system. I'd assume one point of backups is to be able to download your files on other systems.

If anyone can help me with this I would be incredibly grateful. I kn ...

Generating TOTP for 2FA directly from the computer (no mobile device)
cn flag
s.k

On Ubuntu 22.04.2, I would be glad to ear about a native and secure way to generate TOTP codes for using in any given application which needs 2FA.

Do you know an open-source way of doing that directly on an Ubuntu computer?

All tutorial I can find are based on the "mobile app" way (e.g. using Google Authenticator), which I cannot use because I don't have any other mobile device than a laptop.

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.
