How to update mesa drivers?
us flag

How do I know which mesa drivers I'm using and how to update them?

I do not want the latest possible release, I want the latest possible official ubuntu release.

I'm on Ubuntu 20.04 and I'm having a problem with OpenGL that I think could be fixed by a new mesa driver.

I have a shell script that runs several other shell scripts in parallel e.g. ./run_all.sh contains

./run1.sh &
./run2.sh &
./run3.sh &

wait
echo "All 3 complete"

How can I terminate all processes if one of them exits due to an error etc? The && requires each script to terminate successfully but it runs sequentially.

How is dump invoked (fifth field of /etc/fstab), can I replace dump?
am flag

Everyone says that the fifth field of an entry in /etc/fstab should always be 0 because otherwise dump would be used and nobody likes dump because it's old, only supports ext2 and ext3, does not meet modern backup needs and is often not even installed anymore.

From what I have read so far it seems that dump was something that usually was invoked manually or with crontab. Is there a good reason not  ...

I want to ban some DNS requests coming to my named server. The server normally listens both TCP and UDP port 53 and logs the requests to /var/log/named/query.log file. So, I added the following entry to the end of /etc/fail2ban/jail.local:

I think I wrote on my boot partition with dd - can I restore it?
kr flag

Today I tried to make an copy of a Micro SD card to another on Ubuntu 20.04. I used dd to first write an image of the first SD card to my hard drive, then switched SD cards and wrote the image from my hard drive to the new card. However it seems I was careless, at some point during the dd operation my screen went black. I suspect that I did not copy to and from the SD cards at all, but copied my b ...

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.
