How to run kernel 5.19 with Ubuntu 22.04 and ZFS?
gq flag

I have two AMD 6800XT graphics cards that have poor support with kernel 5.15

I'd like to upgrade to kernel 5.19. However, I also run ZFS. The current version in 22.04 is 2.1.5 which does not support 5.19.

https://www.phoronix.com/news/OpenZFS-2.1.5-Released

JonathonF maintained a PPA for ZFS backports. Sadly, he passed away.

Does anyone know if there are plans to update the ZFS packages in 22.04  ...

Getting disk full errors, df says 3GB free

I have a 63GB SSD drive, and since upgrading to 23.04 I've gotten "out of disk space" errors a few times. Has happened with Audacity, and Android Studio

Running df -h at the same time as the last warning gives this result. If 60GB of the 63 are in use, why is only 59M being listed as available?

Ubuntu (mate) notifications

I like the notification feature on my Ubuntu Mate 22.04 but it annoys me, that it shows firefox notifications, but once the big pop-ups go away there is no way to open these links from the bell icon. Is there a way to enable that feature so I could also open the webpages that sent the notification?

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.
