I can create such a graph just fine for a single GPU against 100 - (cpu.idle / #cores), but run into issues when trying to use the mean GPU utilization values, as calculated using sum and cdef.

Below are four situations to illustrate the issues for a machine with two  ...

I've RAID 0 built with mdadm on two disk partition on two separate disks. Is it possible to resize (enlarge) this array by resizing the underlying partition, i.e. do something like stop array->enlarge partition->start-array->mdadm -G -z max and then resize filesystem without data loss?

If not, is there a way to convert RAID 0 to something more flexible and resize it then?

So, I need a solution  ...

Bucket retention policies and malicious actors

I am thinking about how one would implement a good system for guaranteeing that some files are available for a certain set of time. In this particular case it is a backup catalog of some 150 MiB per file.

As part of my implementation I have a bucket with a retention policy set to 1 month. The system that writes this catalog file has a service account which it uses to upload the catalog to the buc ...

How can DHCPv6 server allocate fixed IPv6 addresses to clients if it's not allowed to interpret DUID?

In the STP root bridge election process, how do switches advertise themselves as the root bridge if all of the ports start in the blocking state?

In the STP root bridge election process, all of the switches advertise themselves as the root bridge until they receive a superior BPDU. Every source about STP says that after initialisation all of the ports start in the Blocking state. If the ports are in blocking state, which means they cant forward any frames, how can the switches forward their bridge id in order for the root bridge election process  ...

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.
