How to run a kubernetes deployment on a node and scale on another node/pool?
cn flag

I'm running an b2b application on a GKE cluster (1 pool, 2 nodes). They are normal nodes, because the uptime is critical

However, I've created a secondary pool with Spot VMs with more powerful machines, but I want to allow kubernetes to use it only for scaling purposes.

Let's take this example:

  • current state - default-pool: app-1 (3 replicas)
  • wanted state
    • default-pool: app-1 (3 replicas)
    • spot-pool ...

Very low memory usage during heavy load test
ph flag

I have a wordpress website wich I did a heavy load test on. As you can see below the CPU usage is of course high but at the same time the RAM usage never goes higher than 0,4%. The load test doesn't produce any errors but the loading time of the website is very long. I'm worried that the available capacity of the RAM is not really used. Or is that low RAM usage normal for 10000 clients/second?

Linux Gateway Policy Routing and TCP MSS Issue(maybe)?
cn flag

I have an Ubuntu 20 machine as an internet gateway with two WANs ens160 and ens192. I switch the default route on the gateway like ip r re 0/0 dev160(or ens192) and the clients on the LAN access the web without any problem. But if I want to let a specific user through the specified WAN, such as

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.
