Why I cannot access iDRAC9 remotely?
sa flag

I have a Dell PowerEdge T350 with an iDRAC9 Basic. The server is connected to a switch which is connected to a router upstream which is connected to the internet. Very simple. Both the server's NIC1 is connected to the switch and also the iDRAC's own UTP LAN card. I enabled the iDRAC and I can access the web GUI from another host connected to the same switch (a.k.a. intranet).

QEMU SMP options
gs flag

I'm trying to understand the QEMU smp option.

Currently I have set it to:

smp 4

As far as I understand that should create 4 vCPU (with 1 core and 1 thread I suppose).

Would it be better for performance if I set it to:

smp 1,sockets=1,cores=4,threads=1

or

smp 1,sockets=1,cores=1,threads=4

Because applications can spread the workload more efficiently over cores/threads than over different cpu's?

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.
