Grsync fills up o/s partition if destination is unmounted
us flag

If the designated destination drive is unmounted, Grsync fills up the o/s partition instead of just mounting it, or aborting. How do I prevent that?

I usually remember to check to see that it's mounted, but sometimes I forget, with very bad results.

Thanks for any help.

Can't route sound through bluetooth headset

I use my bluetooth headphones with my laptop all the time. This morning, for no apparent reason, I cannot route audio through them. Even though every indication suggests it should be working, the audio still only played through the speakers (at an especially low volume for some reason).

I tried disabling bluetooth and re-enabling it, even at the BIOS level, then unpairing the headset and repairi ...

Ubuntu 20.04 boot message

I am running Ubuntu 20.04.3 LTS on my Dell laptop. The system all the sudden started displaying large amount of boot messages when starting up. I edited ./etc/default/grub file to modify the lines below.

GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX="quiet"

This suppressed almost all the boot messages,except now I get a string of text below before starting up.

I am currently trying to link my CLion to WSL, but CLion only supported the Cmake of version 3.20.x, not the latest version, so I wonder how to downgrade my Cmake (version 3.21.3) to 3.20.x on Ubuntu

With Xubuntu 21.10 on 2008 MacBook, why does keyboard only function as a 10-key pad?
th flag

Just installed Xubuntu 20.10 on my 2008 MacBook (4,1). Most keys don't function, but one group behaves like a 10-key pad. Selected standard English keyboard layout during install. Tried several other keyboard layouts. None worked. Can't type terminal commands or connect to wifi without alpha characters. Since keyboard seems stuck in a "numlock on" mode, I thought of checking Bios/EFI for a way to disabl ...

I bought a cheap laptop off of Amazon. The company that makes is known as Coolby, it's the only laptop they have. Honestly, it's a great machine and I don't regret the purchase. Extremely high value in terms of price to performance. I got Ubuntu 21.10 installed in dual boot after a digging through the BIOSbit of a fight with the BIOS. The only problem I'm facing is I have no audio. Not even  ...

No WiFi Option & Network Unclaimed Ubuntu 21.04

My network adapter is listed below. I have tried for two days to resolve the issue of having no WiFi option unsuccessfully. I even upgraded from 20.04 to 21.04. There were a couple of times that the WiFi adapter was listed in the Additional Drivers tab of the Update Manager GUI, but it has since disappeared. This issue began when I upgraded from Ubuntu 18.04 to 20.04, which I find funny since the co ...

Empty top bar icons are added every time I suspend my system in Ubuntu 21.10 with GNOME Desktop Environment

I recently updated to Ubuntu 21.10. However, I noticed something strange: Since the update, the top-bar icons move further and further to the left. When I restart Ubuntu, the icons are again right next to the WiFi icon like they should. I think you will understand best what I mean if you look at the following screenshot:

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.
