Akka and Kotlin coroutines: ♡

I've experimented with Kotlin and coroutines in programming Akka. And I must say, I really like the combination so far.
But before I go into it some brief preliminaries for those who don't know Akka and actors.

Actors and Akka

Actors are a programming model that fits cloud native architectures particularly well. Being highly available and scaling horizontally. All while embracing the realities of multiple servers collaborating, server instances coming and going and the network having hickups.

On the JVM Akka is the prominent actor framework. It's been around for a while now and as a result it's highly reliable, well thought out and offers a wide programming eco system. My own interest in Akka is because of its suitability for software systems that can only be built with business events as a key construct and thinking model. And then of course materialized views, CQRS and near real-time data streams play a big role in constructing those systems.

Configure Git to use the osxkeychain

By default, git credentials are not cached so you need to tell Git if you want to avoid having to provide them each time Github requires you to authenticate. On Mac, Git comes with an “osxkeychain” mode, which caches credentials in the secure keychain that’s attached to your system account.

You can tell Git you want to store credentials in the osxkeychain by running the following:-

How to use Mac KeyChain to store GitHub repos credentials?

You know the pain, you cloned a repo over HTTPS, and now Git asks you for your password each time you want to push or pull.

Chances are you already have the git credential-osxkeychain command installed. If not, just install Git with brew: brew install git.

Once installed, just tell Git to use the KeyChain to store your credentials:

git config --global credential.helper osxkeychain

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

Install Terminator (shell)

sudo add-apt-repository ppa:gnome-terminator
sudo apt-get update
sudo apt-get install terminator

Terminator should be setup as default now. Restart your terminal (shortcut: "Ctrl+Alt+T").

How do you POST a JSON file with curl??

You can post a json file with curl like so:

curl -X POST -H "Content-Type: application/json" -d @FILENAME DESTINATION

so for example:

joecliff

var CryptoJS = require("crypto-js");//replace thie with script tag in browser env

//encrypt
var rawStr = "hello world!";
var wordArray = CryptoJS.enc.Utf8.parse(rawStr);
var base64 = CryptoJS.enc.Base64.stringify(wordArray);
console.log('encrypted:', base64);

//decrypt
var parsedWordArray = CryptoJS.enc.Base64.parse(base64);
