`chown postgres` of a subdirectory not working for a new disk

To give postgres more space, I mounted a ssd at: /mnt/fast_data/

What I'd like to accomplish is to give the postgres user ownership to the postgresql directory, so it doesn't say permission denied.

$ sudo chown -R root:root /mnt/fast_data/
$ sudo chown -R postgres:postgres /mnt/fast_data/postgresql/

When I test with:

Ubuntu - ipv4 mostly not working on new install
jp flag

I just did a clean install of Ubuntu 20.04 on a machine and have been having problems with it. IPV6 works fine across the board, but IPV4 isn't working, mostly.

[EDIT: I'll shorten the question in light of new discoveries]

In short, on the IPV6, all works fine. On the IPV4 side, with DHCP on automatic, it was assigned the loopback address of 127.0.1.1, so loopback ping worked. Nothing else IPV4 wo ...

Ubuntu installation HP All-in-one Screen issue
cn flag

I'm having problems with my ubuntu installation in my HP all-in-one. Everything works as expected, but the screen has a lot of moving, shaking horizontal lines. Sorry, don't know exactly the english word. I suppose it must be a graphic card driver issue but I cannot solve it. I have the integrated graphic Intel card. Same situation happens both with ubuntu 20.04 and 16.04. Any suggestions?

Is the trial version of Ubuntu very similar to the full download?
br flag

Is there a difference in how Ubuntu navigates in the Try Ubuntu mode as opposed to the actual download to your system mode? I would like to know before I actually download the full Ubuntu to my MacBook Pro operating system. The trial one I have in my system has a lot to be desired. Can both be kept as operating systems to switch back and forth?

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.
