I got a 12TB and 4TB in a LVM so they look like one 16TB drive.

Program stopped working after system update
lc flag

I've been using the a program called gpuNUFFT for a long time now and after updating my system to Ubuntu 20.04 it stopped working and I'm getting a missing file error:

libcufft.so.7.5: cannot open shared object file: No such file or directory

I tried to look it up and this appears to be a library that CUDA uses to perform FFTs which makes sense why it's looking for it but not why it's missing.

How can I discover which packages were installed or updated in a specific ubuntu-release-upgrader?
in flag

In my /var/log/dpkg.* file, I have the entries upgrade ubuntu-release-upgrader-gtk:all 1:20.04.33 1:20.04.35 and ubuntu-release-upgrader-core:all 1:20.04.33 1:20.04.35

I assume this means these packages were upgraded from 20.04.33 to 20.04.35.

Is there an authoritative source which details which specific packages were installed / upgraded as part of this release?

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.
