Go (Golang) Standard Library Interfaces (Selected)

This is not an exhaustive list of all interfaces in Go's standard library. I only list those I think are important. Interfaces defined in frequently used packages (like io, fmt) are included. Interfaces that have significant importance are also included.

All of the following information is based on go version go1.8.3 darwin/amd64.

Prerequisites

Install Cygwin with make, gcc & g++. Download Redis tar.gz package, unpack it.

Patch

Edit deps/hiredis/net.c and add the following lines just after the include directives:

If your running a x64 bit Ubuntu or other Linux and find USB transfers hang at the end apply this fix:

echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytes

I suggest you edit your /etc/rc.local file to make this change persistant across reboots.

sudo nano /etc/rc.local

#Debugging Scala with JDB

It seems impossible to find answers on how to debug Scala with jdb on Google. I wanted to consolidate what I've learned in a easy to digest guide. Please feel free to comment with other tips I may have missed, or corrections to what's here.
