Golang Workers / Job Queue

A running example of the code from:

• http://marcio.io/2015/07/handling-1-million-requests-per-minute-with-golang
• http://nesv.github.io/golang/2014/02/25/worker-queues-in-go.html

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.

SNI Proxy for sharing an SSL port 443 with Sandstorm

Make Sandstorm and other web server coexist in the same port while keeping HTTPS encryption.

Introduction

The purpose of this tutorial is to set up SNI Proxy so it’s possible to use Sandstorm verified SSL encryption while coexisting with another web server that also uses SSL.

The main reason is to allow other users to connect with your Sandstorm instance in the standard HTTPS port (443) and keep using that port also for any other web apps.

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.
