does adding a rule to iptables mean it takes effect immediately?
in flag

I run sudo iptables -A INPUT -p tcp -m tcp --dport 2222 -j ACCEPT in bash and then tried to connect to that machine via another machine on the same LAN / subnet via port 2222 with PuTTY and it didn't work.

Maybe I need to restart iptables after I add the rule for it to take affect? If so how would I do that?

Here's the output of iptables -S:

Blank screen after installing kde desktop environment, can only login from console tty2
cn flag

I wanted to put KDE plasma on my Ubuntu 20.04.

It did not work - a blank screen came up then I had to use ALT + CTRL + F2 to log in and then command line shows up instead of giving me the direct login access.

In order to get access to the GUI I need to type sudo systemctl restart gdm

I do not want to have to use tty2 console to login.

Thank you

Can I revert back matlab-support installation?
us flag

After installing MATLAB on Budgie I didn't get any launch icon so I opted for the terminal, after a while I decided to do something about it and went for the shortest path possible: I installed matlab-support (using the terminal). In the process I changed some file extensions because the installation recommended to do so, but after openning MATLAB (from the new icon) I stumbled upon this message:

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.
