How to delay restart process in Ubuntu
cn flag

When we restart Ubuntu OS, it goes down, powers off (all connected devices also power off) and then quickly power up again and boots normally. Is there a way to add a delay between power off and power on. So that the system powers off, then wait for x seconds and then boots normally?

Thanks

Does Ubuntu Server have any special preinstalled packages
ca flag

I want to build up my own desktop environment (like an Openbox/i3 setup) from a base. I don't want any pre-existing DE since I want to learn about all the components required to make a running DE on my own. Now the only "flavour" that Ubuntu offers in this respect is "Ubuntu Server". Now, my question is whether the Ubuntu Server ISO comes with any server-oriented stuff preinstalled. As far as I understa ...

I have several new Ubuntu 18.04 servers that were scanned for compliance and vulnerabilities. The scan results show that I need to update certain packages and apply hardening rules. These servers are interconnected, but will not have internet connection.

KVM-QEMU-SPICE: drag 'n drop files from guest to host?
in flag

Spice's guest tools work well for file transfers from host to guest, but don't work from guest to host. Spice's Webdav extension is a good workaround, but it has drawbacks (doesn't work from virt-manager viewer).

Clipboard works in both directions, so why not file transfers? Have I missed something or has there been no solution so far?

I have a MAAS server that deploys Ubuntu workstations.

When I deploy, I paste in a bash script I made:

Is there a way to set this bash script as default? So that MAAS would always use this cloud-init on machines I deploy?

Thanks ahead!

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.
