For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

mdadm

Glossary:

md: multiple devices

command	description
`cat /proc/mdstat`	show status of all raids
`mdadm --detail /dev/md0`	detailed status of raid md0

An Ansible summary

Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

security and hardening options for systemd service units

A common and reliable pattern in service unit files is thus:

NoNewPrivileges=yes
PrivateTmp=yes
PrivateDevices=yes
DevicePolicy=closed
ProtectSystem=strict

How do you make friends with React and FRP? 🤔 Start to develop your application using Focal.

This is a CFP for the ⚡️Lightning⚡️ talk at awesome ReactiveConf 2017. If you'd like to see this talk, please 🌟 star🌟 this summary and retweet my tweet 🙂 #ReactiveConf

Functional reactive programming (FRP) is very popular nowadays. The JavaScript community provides us with excellent tools like RxJS, Bacon, and Kefir. But, as we know, they have nothing to do with React. So how we can use the power of FRP in our React application? Using the correct state management, we can make friends with FRP and React and make our application truly reactive. In my lightning talk, I will talk about Focal
