How should the EFI System partition be made redundant without using hardware RAID?
pe flag

What is BCP for making the EFI System partition redundant without using hardware RAID?

If I create 3x EFI System partitions on different devices and then backup any changes made to the primary (mounted at /boot/efi) to the backup devices (mounted at /boot/efi-[bc]):

  • Will the system still boot if the primary device fails, i.e. will it select one of the backup EFI system partitions?
  • Will the system s ...

Can a node.js application read files stored in a local server?
ca flag

My store's ERP runs on a physical server. I access its data first connecting through a VPN tunnel and then establishing an ftp connection with FileZilla (an ftp connection manager). I was wondering if a node application could do something similar to access that same data. I am no expert in networks, so I have no idea on how to go about it. I found the node package "ftp", but how can I reach my local ser ...

System performance of Rasperry Pi (running k8s) is very poor - how to debug?
tr flag

Summary

I'm running a slim homelab (Kubernetes cluster with few pods, Gitea, Drone, Docker Registry, and NFS share) on a 2-Pi4 cluster, and the system performance is poor. I've noted that the controller node's filesystem looks pretty slow - I'm not sure if that is a cause of, or caused by, the other symptoms. I'm going to reimage and reinstall the controller node on a new SD card in the hopes that that f ...

How to reduce the time it takes a request to pass from a ALB to the actual Fargate Server?
in flag

I have a webhook endpoint where our service provider send a payload which I have to respond to within 2 seconds. I've been getting way too many timeout errors from the service provider, meaning I wasn't able to respond within 2 seconds.

I did some digging as to when the Fargate Server gets the payload vs when the ALB receives it. I went through some of the access logs from the ALB and found that  ...

Dell iDRAC on dedicated NIC not accessible from the server itself
nl flag

I have a Dell PE R720xd server with an enterprise iDRAC license. I have iDRAC configured to use the dedicated NIC.

I can access iDRAC from anywhere except the actual server itself. I could understand this happening if I were sharing iDRAC with one of the four onboard NICs, but I'm not -- it's the dedicated NIC.

Google searches for this were not helpful.

Hanged program not shown up in process explorer
cn flag

This is something bugging me for more than a decade. Occasionally there is a program hang in Windows (in this case a setup program in Windows 10 Pro), I tried to close it from resource monitor and it disappeared after a while. However the window is still shown and I cannot open a new copy of the program. I launched Process Explorer from sysinternals but this window doesn't show in the list.

which K3S ports should (not) be exposed on a public interface

The K3S documentation explains which ports are required for this kubernetes distribution to work.

What it does NOT explain is, which of these ports are OK to be open on a public interface.

K3S seem to deal with the following ports

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.
