Give app access to ssh pub file
ru flag

I'm on 20.04 (Desktop) running DBeaver. I need to add my ssh key to a login.

When I tried to go to my key, it says permission denied. What is the best method to give the app permission to the folder without potentially exposing the file? How do I run an app with different permissions or add it to a group that I can give access to the ssh pub file?

My Ubuntu workstation was frozen, so I used the power button to shut it down.

Next time I booted, it displays this message and remains on a black screen with nothing but this message: /dev/sdb1: clean, 215539/15237120 files, 3398675/60918272 blocks

I have a strange problem. It looks something like version conflict. I mean I have an installed package with a specific version, but the software installed is an other version. But they should the same. For example I have vlc package installed and the package version and the software are the same version. for example:

I recently upgraded my old Lenovo laptop's SSD BIOS from MBR to UEFI / GPT.
It was originally dual-booting Win-10 and Ubuntu 20.04 with Grub-2. I managed to get the Win-10 converted OK and added the Win's Boot partition, but gave up trying to boot the Ubuntu partition, so I finally erased it.
Now- I have an operational Win-10 Insider-Preview partition, and its spanking new Boot partition (NOTE! This parti ...

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.
