nginx reverse proxy with subpath
in flag

I built a web app that will listen on a port and handle HTTP requests. For example, if I run it locally at 127.0.0.1:3000. I can access it with http://127.0.0.1:3000/path/within/app on my browser. I would like to deploy it on one of my servers, which is configured with nginx to handle all incoming requests (and TLS) and forward them to different applications (listening at http://127.0.0.1:xxx).

Cannot transfer data from one specific system (MTU issue?)
my flag

Summary

The default MTU value prevents data transfer for one system. Reducing it manually enables the data transfer once more, but this manual adjustment is unnecessary on an adjacent system.

Background

I have a Backups Server. I have two Raspberry Pi systems in remote locations: one in the UK and one in Albania. Alongside the Albanian Pi is a QNAP (a Linux-derived fileserver). I have an IPSec VPN  ...

How do I configure storage class on an existing k0s cluster

When I run kos kubectl get storageclass I notice it is not provisioned and I have to add it manually. I am little unsure though on the exact procedure. The [Documentation][https://docs.k0sproject.io/main/storage/] says k0s comes with OpenEBS installed. What I am unsure of is how to enable this extension in the config file.

My existing config file has this only (I assume this should be the default  ...

Linux server ignoring packets from gateway
ke flag
ENM

I have a Proxmox Linux server, which is able to send and receive packets to hosts on the local network, but will not process packets from the gateway. This causes internet traffic to fail, so I can't run apt to update packages. All protocols appear to be affected.

VMs running on the server can access the gateway just fine.

I am aware that I can use the windows update catalogue. But then I need to find the exact right driver.

Wireguard forward traffic to host
cn flag

I'm using Wireguard as docker container on a pi. I'm running a couple other services on the pi that I want to be only accessible over the wireguard connection. The wireguard server created an interface wg0 and a subnet 10.8.0.0/24. From inside the container I'm able to connect to the host via 172.17.0.1 so I searched and was able to create the following configuration inside the container:

How to allow a team member to access my Google Cloud Platform account?
sb flag

Google's Play Console allows to invite team members who can manage apps and do changes in behalf of the owner of the apps. This is useful to do work for a customer without requiring him to share his account login information.

Is the same available for Google's Cloud Platform? I'd like to create a project, enable various APIs for Google Maps and receive the API key in behalf of my customer.

How to constraint already running interactive processes with cgroup2
br flag

My home-server is running some aged hardware (Core i5-3450, software RAID1 on SATA disks) and often has problems when I run performance-intensive things like a compile-job besides "normal" services that run in the background (DNS, Web, DHCP, Mail, etc. etc.)

Recently I nearly trashed my system when a compile job got to nearly 100% CPU and in consequence the wait I/O skyrocketed as well and basica ...

Bad I/O performance using software raid 1 on my Linux machine
br flag

I am using Ubuntu 20.04 LTS, Kernel 5.8.0-55 and have my filesystem on a md/software RAID1 consisting of two SATA hard disks as my home server system. 32 GB RAM, 4 cores (Intel Core i5-3450). It has been like that since years, and always was ok, but since some time the I/O performance/latency became worse and worse ("some time" at least in my perception, I am pretty sure it has not always been that bad). ...

I have a question about a new server that I want to buy. This server has 2CPUs and 32gb of ram in total. My question is: can I use all the 32gb of ram for proxmox, and therefore for the vm, or can I use only 16gb?

I am trying to fix issues with very slow Azure App Services to Azure Database connection.

After Wordpress migration form cheap OVH hosting I noticed extremely long TTFB: increase from 300-400ms to 1500-3000ms.

MX record pointing to a dynamic IP
tr flag

I'd like to host simple-login on my home Synology server. For this, I have to register an MX record on a domain that points my IP address.

However, my internet provider does not guarantee a fixed IP, though it's not changing a lot.

If I just buy a domain name, when my IP address changes, this can take up to 72h to be propagated to DNS servers, which is too long.

The only solution I see is using a dyn ...

How to use ManagedCertificate in namespaced Ingress

I tried to use Google Managed Certificate (not through k8s) in Ingress.

If Ingress is in default namespace, everything works fine using ingress.gcp.kubernetes.io/pre-shared-cert: my-cert-name annotation.

However, if Ingress is in a namespace, it looks for a certificate named my-namespace/my-cert-name. But it's impossible to create a certificate with / in its name.

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.
