How to prevent External Secrets from modifying existing k8s secrets if it's having difficulty with the secret store
cn flag

We're using the latest external secrets operator from external-secrets.io to get secrets from Vault and inject them into kubernetes. We had a situation where a Vault KV engine was upgraded from v1 to v2. This caused External Secrets to no longer be able to find the secrets in Vault, and as a result it replaced the values of all the k8s secrets with Null values (""). Needless to say, this isn't the type  ...

Determine available architectures of an apt repo without adding as a source

When working with deb (apt) package repos, you can sometimes browse them over http to determine what is available across different architectures (amd64, arm64, etc). For example, Ubuntu gives a file listing to help browse the repo

However, other sources, such as this Elastic repo, do not allow regular browsing.

My only option appears to be actually adding the repo to my sources (make modification ...

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.
