AWS EKS kubernetes pod received empty response when calling an Ingress URL with pod in same node
us flag

Context:

i recently encountered an issue where a kubernetes pod (blackbox-exporter) will receive an empty response whenever it tries to call an Ingress URL of a pod that resides in the same node as itself. This reflected as an intermittently failing probe on the dashboard.

The ingress controller used is ingress-nginx and sits behind an AWS NLB.

Example:

node1: 192.168.20.2

node2: 192.168.20.3

How much traffic can a heroku page handle?
ch flag

I have recently deployed my rails website with Heroku.

I am currently on the paid Hobby Dyno.

My web page consits of a log in function, 13 five minute long sound files, a few images and a bunch of zoom links. I am expecting around 200 users at any given time clicking around the pages.

Will the hobby dyno be enough for this or should I invest is something more expensive?

Thanks!

When Netfilter performes filtering in TCP/IP kernel network stack?
ng flag

I have a question about where the Netfilter is placed in the network stack in the Linux kernel.

I know that it is Network layer, netfilter and then TCP layer. In fact, after decapsulating the packet in IP layer in the kernel, it will be parsed by Netfilter and then it will be decapsulated in TCP. So I am wondering how it can filter the packets based on port number as it is in TCP header.

The eth0 between Pi and the server is statically configured so that Pi's eth0 has IP 192.168.3.23/24 and the server has IP 192.168.3.200/24. Pi's wlan0 has IP of 192.168.1.131/24.

What is the correct way to enable PHP extentions, manually or via mods-available?

I am used to enabling PHP extensions by manually adding them into my php.ini file, for example: extension=x.so. But today I learned that one PHP extension failed to load because putting the extension=x.so fails because some extensions are loaded after the php.ini is contacted.

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.
