Ubuntu is using QWERTY keyboard shortcuts instead of Dvorak
au flag

I type in Dvorak and today I updated from Ubuntu 18 to 21. Now, when I try to copy, cut or paste text in programs like Sublime Text or the terminal, I can only do so by using Qwerty shortcuts. This is no good as I'm used to Dvorak shortcuts.

So if I want to copy, I'd normally press Ctrl I. But now I have to press Ctrl C.

I think it's a new feature of Ubuntu 20 or something. They must have decided th ...

Is it possible to execute a script with only editing/remove/making files
in flag
Cas

Just curious,

Would you be able to run a script (let's say test.sh) without every doing ./test.sh? You can only edit/make/remove files. A few things I thought about:

  • crontab, and then add a line with the current "time + 1 minute" and the script. But crontab doesn't have a file at a location that you can edit, instead you have to edit it with crontab -e which is a command, so this one isn't an option.

Kubuntu 21.04 night color not working

My system doesn't starts with night color (I have set it to be always on).

Occasionally while I am using my system it starts the night color filter for 2-3 seconds and then it turns off. However the night light indicator on my panel stays on.

If I explicitly restart night color, it shows the same behavior, i.e. turns on the night color and then auto shuts down. The same behavior is seen when I run

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.
