What exactly does the AWS Pay For What You Use policy mean?
cn flag

Well, I was fed up with the absurd host prices here in Brazil when I got to know AWS and the pay-as-you-go policy.

I recently started a course for the solution architect certification (SAA2), that's when I saw in the EC2 module that machines must be turned on/off/rebooted manually which worried me because I thought the way it charged was: If there are users accessing the machine it will be runnin ...

Not really sure where to get support for this or even report it, as basic support requires a monthly subscription.

Passenger not running (Ruby on Rails + Nginx)
ru flag

My AWS instance was working fine with my app. But, today, the server was down without memory ram. Then I run:

sync; echo 1 > /proc/sys/vm/drop_caches
sudo service nginx start

After that, ram memory consumption is ok, but the app not. I'm running a Rails 4.2.1 website with Ruby 2.2.2 and nginx/1.8.0 in a Ubuntu 14 AWS instance.

When I access the site, I have the error:

502 Bad Gateway

Routing inbound and outbound udp traffic to the same port in kubernetes
au flag

This is a follow-up to a prior question I asked, but with a different ask/approach. In case it matters, I'm on GKE, but I'm hoping there's a cloud-agnostic answer.

I'm trying to run the container factoriotools/factorio, but the application has some particular requirements due to the use of an application-specific public server listing function, as seen in many video games that use user-hosted servers. ...

How do routing rules from IPTables, IPVS, and NFTables get ordered from a precedent perspective, in the Linux kernel?

  • In general, is there an order of precedence for when these load balancing / packet filtering constructs are ordered ?
  • NFT and iptables, ...

How to correctly configure a host with two network interfaces so that the docker container can provide services normally?
us flag

My server has two network interfaces, so two IPs, one Internet IP, and one private address.

I added the following script to the /etc/iproute2/rt_tables:

252 enp0s3
251 enp0s8

And added the following script to the /etc/rc.local:

ip route add default via 172.17.171.151 dev enp0s3 table enp0s3
ip rule add from 172.17.171.151 table enp0s3

I recently installed a secondary domain controller within my organization which also holds the DNS Role. If one DC goes down I would like all client machines to look for the secondary Domain controller.

AWS Cloudfront is returning different responses for identical queries

I have an API that is supposed to use accept a website header supplied by the client to respond differently depending on which website the request is for.

I have whitelisted this header in AWS Cloudfront. To my understanding this should mean that Cloudfront includes it in the cache key.

When I repeat identical curl calls to my endpoint I get different results back from Cloudfront.

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.
