I noticed that Software updater often takes multiple tries.

It usually says it can not download files even though my internet is fine. It looks like it only partially downloads file on the first try.

I'm trying to automate the Ubuntu installation process as part of a migration from RedHat, and I have a working kickstart script that I would like to modify for Ubuntu.

I have read several answers here and official Ubuntu tutorials, so I did manage to use the graphical tool to generate the KS script. However, I don't want to alter the ISO image at this point; instead I want to load the KS script  ...

Alias with input
fo flag

pretty new to linux and trying to create an alias that runs a python file here's how it goes.

alias search=("cd /home/SET && python3 /home/SET/search.py")

The only problem is that "search.py" takes and input and it can't be provided due to the parentheses (because I don't wanna change directory to /home/kali/SET Everytime i run it.), So is there anything can i do about it?

Creation of a simple script that renames a file picking randomly from a group of files
ag flag

The idea is to play a "greeting" sound file during startup in KDE.

Inside a folder, there would be, for example, 10 audio files. Let's say, named 1.ogg 2.ogg 3.ogg etc.

The file that actually plays is called greetings.ogg.

How do I randomly take one of these files and rename it as greetings.ogg without losing the 10 original files?

I am trying my best, but I'm failing miserably.

Night light icon shows up - but desktop colors don't change

I'm using a manual schedule for night light - and right now I'm within the schedule. Using Ubuntu 20.04

I see the 'Night light' icon in my status bar - and clicking it shows 'Night light is on', but my actual colors are still as bright as usual.

Dragging the slider from less <> more warm also has no effect on the screen color.

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.
