Reliably prevent apt-get from asking for confirmation when run from cron
cn flag

On my Ubuntu 20.04LTS servers I have a cron job for deleting old kernel versions to prevent their /boot partitions from running out of space. It works by querying with dpkg-query for the list of installed linux-image packages and then feeding all but the last three of those to apt-get purge -y. This works well most of the time.

Every once in a while, for various reasons, this process will select t ...

I used traceroute and the packet is dropping on first-hop only. ...

Ubuntu laptop boots in EFI Shell instead of OS

starting up my laptop this morning running Ubuntu goes directly into EFI shell. Not sure what this failure might be. I have reset a few times and gone into the Boot Manager to see anything unusual in the settings, looks ok.

Is there commands I can run to force my OS to start or could this be another error I need to look for!

Normally, after getting through grub, I'm asked for the password to unlock the disk in some graphics mode. But now I'm not asked for the password, after switching to a graphical command line screen, it stops, the only thing I can do is p ...

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.
