It shows as charging, but lsusb does not show the devices.

I have another Xiaomi phone here (Pocophone F1) that appears as normal.

I know that it can be a hardware problem, but my idea i ...

I can rest my eye by inner color. But I am unable to change outer color. Is there possible way to change outer color either?

How to make Nautils forget credentials for deleted bookmarks?
es flag

Using Nautilus on Ubuntu 20.04, I use a NFS connection to a server for which I have opend through Other Locations> Connect to server and that I have added to Nautilus bookmarks.

Now that I wish to use different credentials, I can't seem to make Nautilus forget the ones I was using. I read here that Seahorse should contain them, but it doesn't.

So, where are they stored?

The Script command issue
br flag

The script command typescripts of everything displayed on your terminal. But sometimes when the output is in colors, it's complaining "output.txt" may be a binary file. See it anyway? if output.txt is the output of the session.

Is there a work-around?

The mystery of starting and restarting a computer. How to fix lag on Ubuntu 20.04?
in flag

Steps when I want to play the game OAD:

  1. I turn on the computer and I systematically observe a strong lag.
  2. I then restart the computer and I systematically observe zero lag.
  3. I then can finally play the game.

So two major steps before playing the game: start the computer then restart the computer

What can be done to fix those lags without being forced to restart a computer?

thx for your input.

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.
