What overwrites an alias created by a file in /etc/profile.d? (environment variables)
cz flag

I executed the following command to create an alias file in CentOS 7.9:

echo 'alias ll="ls -alhF --color=auto"' > /etc/profile.d/alias-ll.sh

Then once I restarted the shell, "type ll" indicated that this alias did not work. I thought this may have been due to another file in /etc/profile.d overwriting the alias, so I renamed the file to "z-alias-ll.sh". Then I restarted shell and this time, "type l ...

Make Firefox's "System theme" darker

I managed to get the close button of Firefox to look like my Ubuntu's (22.04) Yaru-dark. However, it's a bit lighter than the system's dark theme (especially the toolbar). Would there be a way to tweak Firefox's "System theme" theme to be a bit darker? Thanks in advance!

Running without a display manager

As I understand it the display manager asks you to pick an xsession and log in.

I'm running icewm on Ubuntu 22.04 an old machine and just need it to start up and start icewm automatically -- no need for display managers or passwords.

I've switched from gdm3 to ligntgdm (xdm doesn't work) but can I remove the display manager completely since it is entirely useless?

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.
