When connecting pptp, the Internet disappears
us flag

My internet is connected via wi-fi. OS Ubuntu 20.04

I set up a pptp connection. Connected to him. But my internet is down.

In the pptp settings it is written that you need to disable Internet access for the pptp connection.

But in the settings in ubuntu there is no such checkbox.

How can I specify that the Internet would not be used through this connection?

Is it possible to allow NOPASSWD on an alias of a command requiring sudo?
in flag

I added this alias:

alias shutdown2h='sudo shutdown -h +120'

which I would like to run without having to enter the password but also without adding NOPASSWD for the whole shutdown command.

Is it possible to add the alias to the sudoers file with the NOPASSWD alltogether? I tried it with the location of the command ~/.bash_aliases/shutdown2h which gave me a syntax error. Or is there another way?

Help with partition sizes
br flag

I will be installing Kubuntu (latest LTS) on my laptop. It has a 500GB nvme. A couple questions:

I plan to make most of the drive for the /home partition. I don't plan to install a bunch of programs. So is 55GB enough for root?

It appears that I don't need a swap since it will be on an nvme?

This is just a general use laptop used for browsing the web. I'm going to try to avoid dual booting with Windows ...

Mouse weird behavior at startup

When I boot Ubuntu and I click anywhere when it's not fully "loaded", my MouseDown event is stuck. I can still move my mouse but can't click anywhere (mouse is stuck on "drag/mousedown"). When I unplug and replug my mouse, it fixes the problem. Any clue?

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.
