Can you use a SAS fan-out cable to connect more drives?
fi flag

I bought a Broadcom 9400-16e HBA that has four external ports. I was hoping that by using four mini-SAS cables that fan-out to two, I could double the number of connected drives from 16 to 32. However, each fan-out cable can only detect four drives, two per mini-sas instead of four.

I seem to have misunderstood their capability. I understood the throughput would be half for each mini-SAS, but did ...

Ansible : host variable reference confusion

I'm curious about this error that comes up in an online DNS report, and unable to find information about how I might fix it:

Direct Parent Check:    The Parent DNS Server [ns1.xxxxxxx.org.uk] does not have information for your direct parent zone org.uk. This is OK but can be confusing.

I am looking for a way to trigger a shell script when a new NFS filesystem is mounted. This would be used on Ubuntu 16/20 systems.

The reason behind this is that on occasion, the connection to the NFS server is lost (reboot, network latency) and data is written to the underlying mount. The shell script I have written will modify the underlying mount to prevent this (chmod 400) and force the appli ...

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.
