How to autocomplete hidden folders in zhs
in flag

When I used bash, if I had a hidden folder, say .hidden and I started typing its name and hit tab it would autocomplete the name. So for example if I typed .hid and hit tab it would autocomplete to .hidden. I have moved to ZHS and this is no longer true. If I type .hid and hit tab it will beep and not complete. How can I configure ZHS to autocomplete hidden folders? Thanks!

Raspberry Pi-Tools in Ubuntu Core?
in flag

Linux Distributions for the Raspberry Pi like Ubuntu oder Raspberry Pi OS (formerly Raspbian) usually come with the rpi-* and raspi-config to configure/enable the hardware and update the EEPROM and things like that.

In Ubuntu Core I did not see them, neither did I find a snap containing them.

What is the supposed way to configure and update the hardware unter Ubuntu Core?

Can Ubuntu Server be suitable for desktop use?
de flag
Dan

I wish to use a minimal Ubuntu install with the latest stable Pantheon desktop because the performance of Elementary OS 6 is sub par due to the large size of the pre installed flatpak apps. Is Ubuntu server minimal enough to have any real performance impact. Will removing the Snap Packaging Format break the system?

Firefox log in problem
es flag

I have recently converted an oldish computer from Window 7 to XUbuntu and have installed the latest Firefox as the search engine. However, when I log on to Firefox, the computer simultaneously logs on to Terminal Emulator. This does not prevent either program from working normally, so it is more of an irritation than a problem, but how can I resolve this?

Many thanks in anticipation of some help. ...

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.
