Grub doesn't recognize linux-surface kernel

Error when trying to open gedit
in flag

I got a error when opening gedit. It is weird. I don't know how to fix it. I tried:

sudo apt update && sudo apt install --reinstall gedit

But, still getting the same error: enter image description here

Is there are any kind of repair? I don't know if it was because I was following a tutorial with R. However, I did not run any kind of config script.

After click ok it works (after a delay from 1 second +-).

Thank you  ...

systemctl restart reverting application file changes
us flag

I wrote a job(written in Java), which fetches historical data from a broker. I keep track of and update the date of last fetch date in a file.

The job is maintained as a service systemctl. Sometimes this job dies due to external dependency and the systemctl starts the job again automatically. When it starts again, I read from a file which contains what date it has to restart from. The problem is, ...

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.
