mount via cli problem and comparison with nautilus connect to server SAMBA share
zm flag

I would like to know the difference when mounting the network drive via mount, i.e. below and via nautilus -> connect to server.

sudo mount -o user=<USER>,domain=<DOMAIN>,password=<PASS> <server> <mountpoint>

The reason is that, everytime I use sudo mount, I got mount error(13): Permission denied. On dmesg

I have tried to work out what's causing it with systemd-analyze, but that reports a startup time of just 20 seconds, which isn't correct. The only t ...

VirtualBox: No bootable medium found after trying to encrypt dynamic disk
mx flag

I tried to encrypt the dynamic disk (vdi) with VirtualBox's disk encryption, and I didn't realize that it'd fill up the entire space on the host. The encryption resulted in an error because the host ran out of disk space. To shrink it back to normal, I wanted to go into the guest and write zeros then use VBoxManage, but I can't even boot up the guest now because of "No bootable medium". Does this mean t ...

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.
