ru flag

I have a PC and laptop, both running vanilla Ubuntu 20.04. I've just upgraded both to kernel 5.14 (I need the USB latency enhancements). Laptop is working fine, but PC gets ridiculously slow already when loading the login screen. Everything takes like 100 times longer to load, even stuff like resizing a window takes like 2 minutes, so it's basically unusable.

Installing server with cloud-init script?
in flag

I just installed a (physical, bare metal) server with the new 21.10 server install image (in order to test and prepare for 22.04) on a usb pendrive.

Worked, but I did not see an option to tell the installer to use a cloud-init file from my webserver, which would not just ease installation, but ensure, that several servers are installed exactly the same way.

How can I have the 21.10/22.04 server inst ...

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.
