I am new to Ubuntu 20.04 and don't know much about it.

I have my current screen resolution set as 1920 × 1080 (16:9). I want to change it to 1280 × 720 (16:9); but as soon as I apply settings, everything becomes bigger. I have tried a lot of things, but still can't fix it.

why were openjdk 14 and 13 removed from the repos

Today, my CI/CD pipelines died because we maintain several applicatiins which depend on Java 14. Looking at the logs, I saw that their dependencies could not be fulfilled, since they depend on java 14.

Indeed, it seems to have recently been removed from the (focal) repos. The only thing I can find is:

Read-only errors on multiple drives with a fresh install of 20.04 LTS
cn flag

I've been using CentOS for a long time but since Red Hat decided to kill it off, I decided to give Ubuntu a try. However, I ran into problems right from the start. I installed 20.04 LTS first on a new 2TB drive but after an uneventful installation, I started having read-only filesystem errors. I thought the disk was problematic and I used another brand new drive (8TB).

Network does not connect when I boot directly. It only connects when I change boot order to let pxe network boot first on my Lenovo E4125.

If I let the pxe network boot first, my boot time doubles.

Proper way to expand storage on Ubuntu running on VirtualBox with Dynamically Allocated storage? Docker keeps running out of space
ve flag

I used the VirtualBox Media Manager to resize the disk from 10gb to 50gb.

I then used GParted Live to expand the partition to 50gb.

When I boot into Ubuntu and run df -h it shows that ‘/dev/mapper/vg_cloud-Log…’ which is mounted on ‘/‘ is at 100% usage.

What do I need to do to get Ubuntu to see all the disk space?

Ps: I’m running Ubuntu without a GUI.

Copying files and folders, such that access rights come from umask, like for new files and directories

How can I copy files to some destination folder such that

  1. Access rights are derived from umask, i.e. the copied files and folders should behave with this respect as if they have been newly created. - I know that one can apply chmod recursively to a directory branch and all subbranches, but that would also affect other files, not just the copied ones.

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.
