ssh, samba, microserv and apache not working after IP change
ru flag

I installed Ubuntu 20.04.1 LTS and under DHCP address 192.168.0.10 installed OpenSSH, LAMP, Samba, Webmin. I changed netplan to manual IP 192.168.0.10, and everything worked fine, but when I changed the IP to 192.168.0.9 there is no response from any server (ssh, LAMP, Samba...). If I change back the IP everything works again.

UFW status is inactive. Any idea why the server is not accessable?

pulseaudio failed to start while ubuntu 21.04 starts with usb microphone plugged-in

pulseaudio failed to start if Ubuntu 21.04 runs with usb microphone plugged-in. But pulseaudio starts normally if Ubuntu 21.04 runs without the USB, and it still works fine even the USB plugged-in after the system boots.

The log message from journalctl when pulseaudio failed to start :

No sound, probably because of s/pdif
us flag

I'm running kubuntu 20.04 and I get no sound. I looked in alsamixer and found only s/pdif. I suspect that s/pdif is hijacking my sound and diverting it to a nonexisting device. How can I make it go away?

Not able to run a program with a .sh script using Ubuntu WSL
fr flag

I am new to Ubuntu. I installed Ubuntu on Windows 10 to run a program with Linux using ubuntu.

When I double-click on the Ubuntu app I get a shell (believe it is a WSL shell) with my username@Desktop-IULTFHD-. Inside this shell, I get some info on root etc. for couple of lines and my username@Desktop-IULTFHD: $

I type cd to change the directory to the location of the software. Then I run the .sh

How do I enable 2160x1440 resolution on Ubuntu 21.10 on VirtualBox?
ge flag

I am running Ubuntu 21.10 on VirtualBox on a Huawei Matebook 14 2021. The native screen resolution of the laptop is 2160x1440. I have also tried Ubuntu 20.04 with the same results.

I've tried to add the resolution with xrandr, but when I load it, the screen turns black:

xrandr -s 2160x1440

How do I enable 2160x1440 resolution?

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.
