Running command before suspend
ng flag

I've found several posts (e.g., How do I run commands on suspend/return from suspend?, How to run a script before suspend?, Script not running on resume/wakeup in Ubuntu) that describe adding a script in /etc/pm/sleep.d or /usr/lib/pm-utils/sleep.d to execute commands at suspend/resume. However, I haven't been able to get this to work; the script seems to never execute despite having rx permissions for r ...

Share SSH on the web

I have my Ubuntu running in my home network. It has no any port forwards from router that shares Internet. I would like to access my Ubuntu to check log files and execute some commands. It would be nice to have SHH. How to achieve that without direct connection? Can I somehow ask Ubuntu to wait for incoming SSH connection somewhere on cloud?

Gnome crashes several times/day
us flag

I'm running gnome-shell 40.5 on Ubuntu 21.10. chrome-gnome-shell is already the newest version (10.1-5)

Several times/day, I cannot switch windows. I can switch workspaces. The applications bar on the left turns into a square with 9 dots in it. If I hit "ALT-f2 r", then I get the desktop functionality back. I have no idea what's triggering it. Sometimes it's when I open my laptop's lid. Sometimes ...

RDP power buttons don't work

With a clean Ubuntu 20.04 LTS Server running GNOME, everything is working fine when I physically log into the unit. But when I RDP into it as xfce4, the Restart, Shu Down, and Suspend button are all greyed out! The only button that is available is Log Out.

How can this be fixed so I can shutdown, suspend, or reboot via Remote Desktop?

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.
