Folder/source code sharing options between linux guest and Windows host
jp flag

Host is Windows 10, guest is Ubuntu server, running under Virtual Box.

Desired feature is to be able to share a folder containing source code between these too. Basically I want to be able to edit the source code in Windows (vscode), but run the code within Linux.

I am aware of the "shared folders" feature from Virtual Box, however it does have a few flaws, this is why I am looking for alternatives. ...

I'm trying to connect to a website that I own. It's a domain that points to a shopify store.

The browser just hangs when attempting to load the site. When I issue a request using curl I get the following:

I am new to RDP, hence not entirely sure if this is the desired behaviour or not.

I am using RDP on my MAC to connect to clients throughout the office and do minor maintenance on them. Today I noticed that the moment I login via RDP, the currently active user on this machine gets logged off and directed to the Windows 10 Login screen, while RDP starts a new "login" for me where I can control the  ...

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.
