Ubuntu 18.04 DNS Not Working

cjt

I'm having a problem with DNS on Ubuntu 18.04. I think there is a misconfiguration somewhere between netwrok-manager, systemd-resolved and resolvconf.

I can ping IP addresses ok, but not host names:

$ ping -c 3 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=120 time=5.07 ms

Ubuntu won't boot: no irq handler for vector
ky flag

I had been using Manjaro for almost a year, but suddenly one day it started showing a lot of 'audit' messages on the second screen, you know, that 'no irq handler for vector' thing, and just stuck there. It only booted properly after 15-20 attempts. I had seen somewhere that Arch-based distros are known for their sudden issues, so I decided to install PopOS.

The Live USB also kept showing those a ...

Run desktop app in the background
cn flag

I have coded a small desktop utility for Ubuntu and I would like to run it in the "background".

For "background" I mean the app icon will appear in the top menu bar only and not when I switch tabs.

enter image description here

I have google around, but I did not find anything. Does this comes from the framework I am using or from the Unity launcher? Unfortunately I do not know the name of this

This is my .desktop file:

Secondary internal HDD keeps changing permission to read only in Ubuntu 20.04
cn flag

I have 2 HDDs:

  • 80 GB dedicated for Ubuntu 20.04
  • 1 TB for storage

The 1 TB HDD keeps changing permission to read only though I have changed it several times using this command:

sudo chown $USER:$USER /mnt/stuff

I am tired of changing it again and again. Why is this happening and what is the permanent solution for this issue?

Unusual freezing

My PC is randomly freezing. Sometimes it works fine for a few days and sometimes the freeze happens right after boot.

Most commonly, when the freeze happens everything keeps working behind the scenes for a couple more seconds. If I'm listening to music, it continues to play. When I hit ALT + SysRq + F it stops. During this time I perform the REISUB rescue sequence and it works.

On rare occasions, th ...

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.
