How can I force Proxmox resident set size (RES) memory to return to node?
in flag

I am running Proxmox and have noticed that multiple VMs that have Ballooning enabled are reserving memory even after they no longer need it and the nodes RAM usage is above 80%. This is causing other virtual machines to show incorrect RAM totals example a machine with 2GB min 20GB memory is showing as having a total of 10GB with free -m

In this example below VM ID 159 is reserving 10.8GB of RAM.

Do ephemeral port numbers run in sequence for the whole system, per process or per listening port?
in flag

We have an application and we use the ephemeral port number to identify the connection. We listen on two different ports, one for normal connections and one for SSL connections. I want to avoid the situation where the port numbers clash because the OS is assigning the ephemeral port numbers per listening port instead of per process or across the system as whole.

We are hosting on Windows but woul ...

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.
