Odd terminal behaviour regarding keymap on Ubuntu 21.10
eg flag

I'm running Ubuntu 21.10 on an iMac 21" (18,2), and I'm in the UK.

Using the standard Mac keyboard, the best layout I've found is simply English (Macintosh).

All works fine, with the exception of the "3" key in the terminal. Shift-3 should give me "£", and Alt-3 should give me "#".

Everywhere else this is absolutely fine, except from within the terminal. I've tried the built-in one (gnome-terminal)  ...

psensor stopped showing CPU temperature after AMD Ryzen upgrade
cn flag

Recently I've upgraded my AMD Ryzen 5 2600 CPU to AMD Ryzen 5 5600x. psensor used to show the CPU temperature properly with the 2600, but after the upgrade, all I see is "temp1 0 degrees" (image). Other temperatures (GPU, SSD etc.) shows properly. I've un/reinstalled psensor but it didn't work. Is there a fix to that?

PS: I've also updated my BIOS version during the CPU upgrade if it is related.

Size of a package: "Installed-Size" vs "Size"
at flag

I am trying to find out a package size. I tried the following command:

$ apt-cache show mlocate | grep Size

Does "Installed-Size" mean size after unpacking the package? while "Size" means the size in RAM?

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.
