Feathers, Michael. Working Effectively with Legacy Code. Sixth printing, July 2007.

Foreword:

• Software systems degrade into a mess.
• Requirements ALWAYS change.
• Your goal as a software developer: Create designs that tolerate change.

What is NDK

NDK (Native Develop Toolkit) is a toolchain from Android official, originally for users who writes native C/C++ code as JNI library. It's not designed for compiling standalone programs (./a.out) and not compatible with automake/cmake etc.

What is Standalone Toolchain

"Standalone" refers to two meanings:

1. The program is standalone (has nothing connect to NDK, and don't need helper scripts to run it)
2. The toolchain is made for building standalone programs and libs, and which can used by automake etc.

(Optional) Why NDK is hard to use

By default, NDK uses android flavor directory structure when it's finding headers and libs, which is different from GNU flavor, so the compiler cannot find them. For Example:

The problem

I have one computer and two different github accounts. One is for work, the other is for my personal stuff. I can't use the same ssh key twice, so I have to use different ssh key for each of my accounts. How do I do that? How do I switch between these ssh keys?
