So i recently made a dual-boot with Ubuntu unity 20.04 And Windows 10 Pro, but I noticed that the bootloader has changed to GRUB.

Re-installing Ubuntu without affecting Windows partition (dual-boot)
cn flag

I want to re-install Ubuntu but I am afraid to start because I am using a dual-boot and don't want to affect my Windows partition.

Has anyone done this before? Tutorials I'm finding is how to reinstall Ubuntu not considering a dual-boot, and tutorials on how to set up a dual-boot, but not in combination.

Any input/known tutorials would be very much appreciated.

Wifi interface seemingly disabling itself?
cn flag

When I booted my laptop today the Wifi suddenly wasn't working and I've been trying for the last two hours to make it work again. I think I fixed an issue or two down the way but I didn't really document anything. The problem I'm unable to solve now is this: My Wifi interface seems to be disabled and I can't (always??) enable it. But even when I was able to enable it the Wifi still wasn't working.

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.
