Network tap is giving hostname of tapping device in logs
za flag

I am trying to set up a network tap between my router and devices to do some home monitoring stuff. Everything is working, I can see ingress and egress traffic being logged via Suricata and Zeek/Bro. The only issue is that in the logs, even though all the IPs are different with different hostnames, it's putting the same hostname for all devices like that of the mirrored traffic host (dell-optiplex).

Yesterday I finally updated Ubuntu to 21.04 from 20.10. The update went well, but after a reboot the system was stuck on my motherboard's splash screen.

and

5.8.0-59-generic

When I pick the second one, the system boots, but everything's kind of weird and glitchy. But it worked well enough for me to open the driver setti ...

How to install a previous version of Gimp with Flatpak on Ubuntu 20.04?
cn flag

I'm on stock Ubuntu 20.04.2, and I have managed to install the latest / current Gimp with Flatpak: it was the 2.10.24 version at the time.

However, there are a few issues with the 2.10 line that I can't seem to be able to resolve.

For this reason, I would like to install Gimp 2.8.

I know that that older Gimp version may rely on an older Python version as well, so installing the whole thing with Flatpak ...

This is my first post so excuse me if this is bad and let me know if I left out any info. I recently installed ubuntu on my Aorus 15g laptop. Even though my second monitor is plugged in and connected via a the hdmi port on my laptop, the screen says "no signal detected".

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.
