How to open program windows on the screen where it was clicked on instead of where the mouse is currently?
us flag

Using Ubuntu 21.04 (Wayland) on a laptop with additional external monitor. Never changed anything regarding application on-screen location AFAIR. I started with Ubuntu 16.04 and always upgraded in between, so it's likely that some settings may be different to the fresh-install default if Ubuntu changed them in the mean time for fresh installations.

Currently program windows open where the mouse c ...

I need to run sudo service postgresql start every time when I start Ubuntu on WSL2.

How can I make the service start automatically when I start Ubuntu?

WSL doesn't use systemd, so sudo systemctl enable postgresql doesn't work.

Why are my file names hashed when I access them from my Google Drive Files on text editors?
za flag

When I try accessing my Google Drive folder on VS Code, the file names seem to be hashed and do not appear by their name. This is very annoying. I have tried different editors as well.

I have tried atom, pycharm, and sublime text. The only one that seems to work is Notepad++. I really want to avoid using Notepad, so are there any solutions to this?

I have been experiencing this for a long time. I lo ...

How can I rescue my Ubuntu VM, if I can't find the */boot/grub directory anywhere?

Something happened to my Ubuntu (v20.04 I believe) VM that I was working on, and it throws me into "grub rescue> " mode, doesn't even let me boot otherwise.

I've done some research on the internet, but unfortunately it hasn't been a fruitful endeavour, since the only solution I've come across doesn't work for me. Here's what I found:

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.
