As part of our backup system, we replicate zfs datasets from a TrueNAS system to a couple of backup servers, one of which is running TrueNAS Scale and has a LTO-5 tape drive connected. We occasionally write one of the read-only snapshot's contents to tape. As some of these datasets are large, tar is used with the --multi-volume flag.

WSUS drivers supersedence
tn flag

I have added the driver classification in wsus and now i have 100k driver updates. The supersedence is not specified so i can't easily decline old updates. I see a lot of duplicate versions for the drivers (update id is different so it's not the same update).

In the past this was bad but since i added windows 10 it's almost unmanageble.

Force deployment on Rancher when AWS CodeBuild produces a new container image
in flag

I have a Rancher 2.5 cluster running on AWS EKS. My CI is done in CodeBuild via a webhook to a Github repo. The buildspec.yml works fine to run the build, tag the containers and then send them to my private registry on AWS ECR, but I have not found an easy way to then trigger an update to the deployment on the cluster to let it know a new container version is available. How do I do that?

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.
