I just freshly installed Kubuntu from a KUbuntu 20.04.3 LTS ISO.

The wi-fi is not working yet so I need to install dkms to add, build and install the rtl88x2bu driver.

But strangely it won't install although it is a fresh installation.

How do I prevent Ubuntu from deleting an older kernel image
ru flag

I currently have this problem. In order to work around it, I have so far configured grub to keep booting from the 5.11.0 kernel.

Next time there is a kernel upgrade, I expect Ubuntu will install the new kernel and delete my 5.11.0 kernel. I would like to prevent this, as the the 5.11.0 kernel is my last known working kernel.

I think I can prevent linux-image-5.11.0-46-generic from upgrading by apt-mark ho ...

Why does Ubuntu Make CF Cards Read Only?
aq flag

I'd like to edit some files on Cfast and CF cards in Ubuntu, but no matter what I try to do all tools available fail to allow me to write. The Cfast and CF cards are writable in Windows and there are no hardware locks on these like SD cards have. From all I read on these forums, it seems no one has ever figured this out so I doubt there is a way to get Ubuntu to allow writes because of how it's develope ...

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.
