Golang Workers / Job Queue

A running example of the code from:

This gist creates a working example from blog post, and a alternate example using simple worker pool.

TLDR: if you want simple and controlled concurrency use a worker pool.

Generate private key (.key)

# Key considerations for algorithm "RSA" ≥ 2048-bit
openssl genrsa -out server.key 2048
    
# Key considerations for algorithm "ECDSA" ≥ secp384r1
# List ECDSA the supported curves (openssl ecparam -list_curves)
openssl ecparam -genkey -name secp384r1 -out server.key

#MongoDB 3.2.x SSL with Letsencrypt Letsencrypt is an initative which aims to increase the use of encryption for websites. It basically allows people to apply for free certificates provided that they prove the they control the requested domain. We will look at the what is needed to secure your MongoDB installation. For more details on setting up a MongoDB server see MongoDB 3.2.x.

##Set the hostname We sould to set the hostname to match the name of the certificate we are going to optain.

sudo hostname mongo0.example.com

Then update the hostname file to set the server name permanently.

Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of advantages of using submodules:

You can separate the code into different repositories.

I have been promoting the use of Sass' @extend function for some time now so it is safe to say that I have been very cautious of how this feature processes Sass into CSS. I still stand behind this feature and it is extremely powerful, but with power comes responsibility.

In a recent project I needed to apply some basic styling to some heading tags, we have all seen something like the following.

h1 {
  @include heading();
}

Lower Case JSX Convention

All lower case JSX tags will now be treated as HTML/SVG elements. They will no longer be treated as custom components in scope.

The React element produced by JSX can be either a React class that exists in the local scope or a global scope HTML/SVG element depending on a convention.

Previous Behavior

Currently, when you use React JSX to define a HTML element you can use any known HTML tag. E.g:

	var http = require('http'),
	fs = require('fs'),
	util = require('util');

	http.createServer(function (req, res) {
	var path = 'video.mp4';
