How to recover from missing partition
US flag

my issue comes from a co-worker who has somehow corrupted an important 7TB hard drive. I believe they filled the space on the disk to 100% over the weekend and somehow messed up the partition information, but I can’t know for sure.

Anyhow, I’m in a pickle. Where once there was a partition like: /dev/sdc1

Now the partition is gone (though the sdc disk is still present). I need the data on that di ...

Why is Ubuntu booting slower if I disable quiet boot?

I don't really like quiet boot, because it shows only a splash screen, which is not too informative. To increase verbosity, i always remove quiet and splash from /etc/default/grub to be able to see kernel boot process:

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.
