Ubuntu 22.04 with horizontal tear on MSI z16
gb flag

I've been getting this on my MSI z16 and I wonder if anyone else have and if so, how they went about solving it. The weird thing about this tear is that it water-reflects the graphics. What you're seeing is that I'm on Google Colab but now it's reflecting the top of that page upsidedown.

I have Nvidia 535.54.03 with CUDA 12.2

Is there a way to edit sshd_config without disabling it and enabling again?
la flag

so I would like to know if there is any way to edit sshd_config without disabling it, then enabling it? I'm asking because I want to create a few Match User options but I don't want to disable it because it is going to close my connections.

If not, is there any other way to remote port forward? I want to allow a specific user to connect to server via ONLY ONE SPECIFIC PORT in the ssh server.

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.
