Cannot boot anymore on full root LUKS volume
cn flag

I have a server with a 300GB SSD set up as encrypted LUKS volume with default partitioning (all into the same place / /home etc.). Recently I started to get the / volume full with unknown stuff (it's mostly a bare bones Linux install used for CUDA workloads). I simply couldn't pinpoint what was the culprit from the terminal with various commands like df -h and complex find size args. I also couldn't i ...

tty1 and switch users not working in ubuntu 20.04
in flag

I very recently switched to ubuntu, and am having a problem with the switch users and the tty1, I've seen in a post here that tty1 is supposed to be the gui login screen and gui desktop on tty2. However ctrl+alt+f1 gives me a black screen with a cursor and hands, if i switch to tty2 it gives me a tty2 terminal session. i am using gdm3 if that helps.

livepatch not livepatching very much
cn flag

I have been running canonical-livepatch for a year or so but constantly find that I have to reboot my server due to kernel patching. Now recently I have been running Linux kernel 5.11.0-1021-aws.

Then recently came a security patch https://ubuntu.com/security/notices/USN-5135-1 which was installed (automatically). Now the system requires me to reboot because of this tiny patch.

Applications cannot start or close
ng flag

I'm using Ubuntu 20.04 and just came across a very strange issue: I was developing an asynchronous application in PyCharm while I noticed that the application that I was debugging did not terminate. kill -9 didn't do anything. I closed PyCharm, but nothing happened.

I opened Firefox, but it told me that I should first close Firefox. So, I identified all running Firefox PIDs and kill -9 them. But stil ...

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.
