What does "routes" mean? [Netplan, YAML file]
nu flag

Here's an example I've taken from somewhere:

routes:
    - to: default
      via: 10.225.192.1

I've seen that this syntax has replaced the "gateway4", however, I've searched for infomation about the concept "route" and seems to be different from "gateway".

Here is what I know:

gateway: It is the ip of the device that allows us to connect to other networks.

Ubuntu 22.04 USB Not Working on M2 Macbook Air

I have been using Parallels on my M2 Mac to run Ubuntu for the first time, and I absolutely love it. However, I am only on the free trial and I think it's kinda useless to spend $120/year just to run Ubuntu with a decent amount of memory. So I tried to use Ubuntu's USB install method for Mac, but I assume it is not available for Apple Silicon Macs as when I try to boot into Ubuntu, the USB will not show ...

Can I just try another desktop enviromment?

I've been using Ubuntu for a few years now, always just "as-is". I'm starting to think it could be fun to try another desktop environment than the default, but I'm somewhat reluctant to try it out - last time I did that (many years ago), it introduced lasting, detrimental and irreversible changes to my installation. I don't think trying out another desktop it worth that, so my question is: Is this still ...

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.
