Duplex Printing not working in ubuntu 21.10
cn flag

duplex printing does not work in ubuntu 21.10 within applications like LibreOffice, Firefox or PDF-document viewer. I can select options like double side long edge/short edge, but it always prints single side. It just works with the HPLIP-Toolbox. Obviously the HP Toolbox is using different printer drivers. Somebody an idea how to solve this problem?

Ubuntu 20.04 Freezes randomly and media loops the last 1-2 seconds clip

After a few days of installation of Ubuntu 20.04 on my Desktop system, I am facing this issue of my OS freezing at random intervals. Happening 2-3 times a day.

The question may be similar to this one but the those answers are not applicable because I already have 16 GB of SWAP and a recent kernel version.

I also checked many other similar questions but could not find the specific solution.

How to translate-shell text to audio mp3 even when the text is long?
us flag

I want to convert text to voice with translate-shell, but it doesn't work if the text is long.

This script works (I think because the text is short):

trans -b :fr "I have a question, I want to convert text to voice with translate-shell but why can't convert long text? Please help" -download-audio-as textaudio.mp3

This script doesn't work (presumably because the text is too long):

ASUS Xonar AE support?

My new system came packaged with a Xonar AE card that surprisingly worked with Ubuntu right out of the box... sort of.

This card has a 7.1 configuration, and I have speakers connected to front, center, and side jacks. The problem is that only the front speakers work. Alsamixer doesn't show any output channels at all with that card selected. Will the center and side channels work at all with this  ...

Renaming GRUB Entries - Grub Customizer Does Not Rename

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.
