Laptop suspend not working with open source drivers
my flag

I have trouble with the suspend feature on my laptop when using the open source drivers that Ubuntu installs. When I close the lid (or suspend manually from the top-right menu) the laptop screen locks up and goes to the login page, but there's nothing I can do anything to get out of that state, be it mouse or keyboard input. The only way out for me is to forcibly shut down the laptop by holding the pow ...

setup: Ubuntu 21.10 (with latest updates). The problem happened even before 21.10 was out. I just never bothered fixing it until now.

zfs version is:

my flag

I'm using Ubuntu 21.10 impish indri.

For some specific hardware support, I'm advised to upgrade to kernel 5.16 (mainline). I tried manually installing the .deb files and installing them using dpkg -i. However, I'm getting dependency issues:

The following packages have unmet dependencies:

Disable .pythonrc only in Python 2

Thanks to this assignment:

export PYTHONSTARTUP=~/.pythonrc

I can start an initialization script as soon as I run Python, a bit like the .bashrc file. The problem is that this works on both Python2 and Python3, instead I want to prevent Python2 from doing this, due to hassles with code in .pythonrc.
I know I can put an If in the .pythonrc file to block its execution in Python2, but I would like to ...

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.
