NetApp SVM management web interface 404 error
cn flag

I created an SVM with the intentions of delegating administration to just that SVM (my first time doing this). I created an aggregate for it, created an SVM, assigned the aggregate to the SVM, created a separate account for the SVM and assigned it a management LIF. I can access the SVM via SSH and that seems to be working fine. But the web interface for the SVM gives a 404 error: Not Found The requested ...

How to whitelist egress traffic with a NetworkPolicy that doesn't prevent Apache Ignite from starting up?
ru flag

I have some more or less complex microservice architecture, where Apache Ignite is used as a stateless database / cache. The Ignite Pod is the only Pod in its Namespace and the architecture has to pass a security audit, which it won't pass if I don't apply the most restrictive NetworkPolicy possible for egress traffic. It has to restrict all possible traffic that is not needed by Ignite itself.

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.
