audio from different user (su) on xubuntu 20.04

I am using firefox on a different user, for example with:

LANG=C xhost +SI:localuser:${1}
su ${1}

or

xhost +SI:localuser:$1
sudo -u $1 -H /usr/bin/firefox -P

Since the upgrade from 18.04 to xubuntu 20.04, I have no audio on the firefox-user, but this user is still part of the audio group. In the PulseAudio Preferences, one setting must be activated. I guess it was "Network Server" "Enable network  ...

Ubuntu 21.04. Question about using an old app
in flag

I found a Linux app called LuckyBackup. I checked the changelog and it was last updated in 2018. Safe to use an old abandoned app like this? Or best to not use it?

I’m new to Linux.

The LuckyBackup UI looks good, but there’s other apps I can use if LuckyBackup is not safe.

Cryptsetup "Warning" that shows up on boot
pg flag
ItM

I'm getting this warning every time my computer boots up and the encryption password screen shows up:

crytsetup: WARNING: cryptdata: Ignoring unknown option 'nofail'

Is there a way to disable it, or "fix" it?

My system uses Kubuntu 21.04 with the 5.11.0-25-generic kernel, and is encrypted (using lvm/crypt).

Thank you!

where to find an example png file which has date and time metadata that eye-of-gnome (eog) shows
cn flag
dan

I'm using xubuntu 20.04 and have installed the eye-of-gnome (eog) on it.

The version of eog is GNOME Image Viewer 3.36.3

On the right side of the eog window (which is called "Image Viewer") there's a column of "Properties". This includes Size, Type, File Size, and several other items, and it ends with Date and Time.

For the photographic jpg files that i have the Date and Time fields are populated.

Problems with the install of Ubuntu on a windows machine
vn flag

I currently run Windows XP but the machine is one I built and will run a 64 bit OS.

I downloaded the ISO file from the download site burnt a bootable DVD with the ISO. The machine boots up just fine then runs a file check - this is also fine.

After waiting for the DVD to stop, the screen freezes with a picture of a large cat. Repeat burn with different burn software, three times - same result.

Any idea ...

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.
