Unix software development:
	- Where I came from, there was a class on this
	- You can piece it together from 228 and 430
	- At some point, we'll move toward CS253 Systems Programming

Pieces that you'll need:
	- compiler  (examples:  gcc, clang)
	- text editor (examples:  vim, nano)
	- documentation (examples:  man)
	- build system (examples:  make, maven)
	- shell (examples: bash, csh)
	- (optional) versioning system (examples:  git, cvs)
	- (optional) debugger (examples:  gdb, various frontends)
	- (optional) IDE  (examples:  eclipse, kdevelop)

What language?
	- Traditional:  C
	- Slightly less traditional:  C++
	- High level:  Python
	- If Unix = OSX:  Objective C or swift
	- If Unix = Android:  Java
	- Up and coming:  Go
	- New from Apple:  Swift
	- Memory safety for C/C++:  Rust
	- Functional choice:  LISP or Scheme
	- Most of the others work too.

Would you like a recommendation?
	- You'll learn Python, C++, and some C here
	- Learn Go, Swift, Java, or Objective C
	- Write a significant program in Scheme

General process to build a program that somebody else wrote:
	- Acquire program
	- Resolve dependencies
	- Build with build system

Example:  Let's build the game engine design example from last term
Example:  Let's build vim from source
	configure, fix dependencies, make, make install

A brief primer on unix programming using C:
	Manual section 2 vs. 3 vs. 7
		- man man
	You'll have to learn to program in C to do this
		- CS430 if not sooner
		- Sometimes in CS250 or CS312
	Python generally has wrappers for library functions, system calls, etc

Ok, the goal:
	Add up all the numbers in an input stream (stream_adder)
	Adding an argument to set the operator
	Calculate total bogomips
	Calculate the number of interrupts handled by each processor
