The wifi is not connecting automatically and I do not know the type of drivers I need for that. I know the software update app itself is supposed to inform me about that, but it can't tell since there is no wifi.

Since upgrading to Hippo, my Insignia Fire TV I use as a monitor doesn't come back after sleep even though my LG TV does. I have them as dual monitors extending desktop. Both are HDMI, though the Insignia uses a DVI converter since my video card only has one HDMI port.

Sometimes a reboot is enough to bring it back, sometimes I have to shut down and sometimes I have to pull the power plug (shut fl ...

Install 20.04 for wsl2 if Microsoft Store is dysfunctional?

Is there any way to install 20.04 for use with wsl2 that doesn't depend upon Microsoft Store (or Add-AppxPackage) working?

Why: Microsoft Store and Add-AppxPackage are broken on my computer, attempts to fix them were unsuccessful, and Microsoft's only solution is "reinstall Windows" because there's no way to just regenerate it, or to uninstall and reinstall Store by itself. Others have already dis ...

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.
