Changing font styles of lightdm-gtk-greeter
br flag

I can change my font using the following option in lightdm-gtk-greeter.conf:

font-name = ...

But I'm not sure how to change the size or weight. I tried putting the following CSS in my GTK theme:

#login_window .entry {
  font-weight: 900;
}

But it's not really working. Exactly which classes should I target to change the font style of the login window?

Is it possible to install multiple version packages when installing Ubuntu apt mirror?
cx flag

You are about to install apt mirror for Ubuntu 20,22 OS version.

Can I install apt-mirror for the above two OS versions on one physical server?

For example, after installing version 22 OS on a server, you can install apt-mirror, and you can install apt-mirror for version 20, which is a subversion.

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.
