how does a striped RAID work with large number of disks?
jp flag

still trying to configure my large (24) array of disks (2.4TB) for an archive/nas of mixed huge and small files. But apart from this, I am now more focused to understand how striped RAIDs work under the hood but more I read and more I get confused because most of the literature's example are based on "low" number of disks (I asked the producer but he was reluctant to answer publicly some of those questi ...

HAProxy NOSRV without any Queue entry before?

I occationally observe NOSRV log lines. I'd expect that the stats UI shows me some value under Queue-Max for that backend. Is my assumption wrong?

(That backend is configured with a cache, if that matters)

CentOS - listing size of top-level directories in a 50TB NTFS volume is way too slow

What I want to achieve is get the information about how big are the top-level folders in a directory (which is a NTFS volume) on a CentOS7 server. This information is placed in a Prometheus file, which is used in order to send this information into a Grafana dashboard.

Windows 10 ignoring routing table
pk flag

I have a Windows 10 PC that has 2 network interfaces. One of those interfaces goes into the main LAN where the fileserver, dns and the router for the internet are located. The second interface is a tiny LAN which has an PLC and an HMI. They both are physically in the same LAN but on different subnets (sorry, can't change that, outside my control).

So I have two physical interfaces and one logical ...

Implementing mixture of thin- and fully-allocated LVs that change dynamically
tr flag

Using LVM, I need to have some logical volumes which are fully-allocated (reserved space) and others which are thin-provisioned. My challenge is that the balance between them will shift dynamically. How can this be achieved?

For example, I might want 20% of the VG to be fully-provisioned LVs and the remaining 80% allocated to a thin pool. But this balance might change to 40/60, and the thin po ...

Is it okay to generate CSR from one of the running EC2 instances for configuring SSL certificate

I'm a total newbie.

I want to set up SSL for my domain (I used elastic beanstalk to deploy my little project).

I have bought the SSL certificate but have not yet configured it with my domain (I'm using the default domain that AWS gave).

I'm also using auto-scaling groups, so the number of instances running may vary (min: 0 and max: 3).

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.
