I've been running Ubuntu 16.04 and recently have been getting regular messages that there is "no space left on device". I'm concerned that this will cause problems if I try to update to Ubuntu 20.04 LTS, so I would like to fix this first.

I have followed all the recommendations I have found in other threads, but the problem persists. Here is the output of df -h:

I figured that I would look into it later and enroll a key after I learned what it was.

I learned that in order to have secure boot on ...

Problem after yesterday's update of linux libs 5.4.0-77

I am experiencing a strange problem with the update that was shipped yesterday (linux libs 5.4.0-77). The machine is stuck in the update with:

update-initramfs: Generating /boot/initrd.img-5.4.0-77-generic

It is reading very slowly all the disks as it seems, the process mdadm and later grub-prob ran over night, spending several hours of CPU. Any hints on what is going on?

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.
