Installling Ubuntu Server 20.04 on a X99 Motherboard with Intel Xeon E5 Processor
ge flag

I assembled a Machinist X99 motherboard server machine with Intel Xeon E5 v3 2690 processor and by now I'm trying to set up a Ubuntu Server on it. I got Ubuntu Server ISO with YUMI bootable USB, but I cannot finish the process because in the last screen appears an error message about "ubiquity". My question is: what is this error about and how could I fix it to finish the booting process?

23.04 : how change font in interface, gnome-shell, window title bar?

might sound obvious, but I can't manage to change font in lunar lobster interface.

In previous versions I used to do it with gnome-tweaks, to change font from Ubuntu to Ubuntu Condensed.

Today it seems to only change gnome-shell font and nowhere else.

Is this expected or a « bug » in my installation ?

Why does libm-2.x.so not install on 22.04 with `build-essential`?

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.
