I would like to change the color of the dpkg-reconfigure dialog in Ubuntu. Under Ubuntu, the color is normally pink, and I don't like that color; I prefer it to be blue like Debian. How do I make it blue?

Improving Virtualbox Performance
tr flag

I have a virtualbox6.1 VDI and I want to improve its performance on Ubuntu 20.04 running on a HDD / SSD hybrid machine. With the /home partition being on the HDD.

My question is..

Can I safely improve the performance of the VDI by placing it onto the SSD root partition? (Are there security issues or other problems that I need to consider?)

Some space seems to be lost on an ext4 drive on Ubuntu 20.04
es flag

Today I "found" a HDD in one of my systems that I completely forgot I had. So I wanted to look inside and see what was in there. I logged in via ssh from another computer (may be important for the following) and, after quite a bit of fiddling around(*), I managed to mount it and inspect it. It had about 65G of data in it. I copied all what I wanted to preserve and then rm -rfed the rest.

Now df tells ...

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.
