1. Represents solutions to problems in domains

2. Encoded into a program that (after compilation) runs on a computer

3. Software means to represent solutions to problems in programming languages

What is Software?

• Complexity of the problem domain (A)• Complexity of the implementation (B)

• Multiplied together in the coding process. (A*B)

A*B >> A+B

Why is software complex?

Software is amazing: 1010 times “better” than human action, at much lower cost than hardware.

Why is this important?

But:It is hard to create: it is “complex”Progress toward better software creation has been slow – this used to be called “software crisis”What happened to “soft” in software?

A brief history of software

1950: user, domain expert, programmer are the same person

1970: programmer writes program, domain expert, if any, is consultant

2010: domain experts’ contributions is paramount, but Domain Orientation is not yet the norm

John von Neumann 1954- Father of the modern computer

Problem ~1950

Insight: Distinguish and treat separately Problem (A) from Program (B)

FORTRAN, 1954First Domain Specific Language

(DSL)

John Backus

From “Preliminary Report: FORTRAN”, IBM, 1954

Turing Award 1977

COBOL, 1957First “non-programmer” DSL

Rear-Admiral Grace Hopper Creator of (predecessors to)

COBOL Wrote first compiler

From MATH-MATIC and Flow-Matic Manuals, UNIVAC, 1957

Found first “bug”

“A programming system called LISP (for LISt Processor) has been developed for the IBM 704 computer by the Artificial Intelligence group at M.I.T. The system was designed to facilitate experiments with a proposed system called the Advice Taker, whereby a machine could be instructed to handle declarative as well as imperative sentences and could exhibit “common sense” in carrying out its instructions.”

LISP, 1959First DSL language system

John McCarthy

From “Recursive Functions of Symbolic Expressionsand Their Computation by Machine, Part I”

- - John McCarthy, MIT, 1960,

First language system for developing Domain Specific

Languages (DSLs)MIT Stanford 1962

Invented (the term) Artificial Intelligence

Invented garbage collection (1959)

Turing Award 1971

“The purpose of the algorithmic language is to describe computational processes. The basic concept used for the description of calculating rules is the well known arithmetic expression containing as constituents numbers, variables, and functions. From such expressions are compounded, by applying rules of arithmetic composition, self-contained units of the language -- explicit formulae -- called assignment statements.”

Algol, 1960First DSL for programmers

Peter Naur et al

From “Revised Report on the Algorithmic Language Algol 60” (1960)First DSL for programmers

Developed in committee with Naur, Backus,

McCarthy, et alTuring Award 2005

Problem and Program are still intertwined causing the A*B complexityHow can we separate A from B?

A and B more useful if separated

Idea: Change B to B’ (meta B) so that we canGenerate: A B using B’B’=Kolmogorov complexity

Data, Information, Knowledge

• Data: unprocessed facts and figures – “The price of crude oil is $80 per barrel.”

• Information: data that has been interpreted – “The price of crude oil has risen from $70 to $80 per barrel”

• Knowledge: information, experience and insight– “When crude oil prices go up by $10 per barrel, it’s likely that gas

prices will rise by 14¢ per gallon”

Making Sense of Data and Information, Elsevier 2007

Knowledge

“We know now that the source of wealth is something specifically human: knowledge. If we apply knowledge to tasks we already know how to do, we call it 'productivity'. If we apply knowledge to tasks that are new and different we call it 'innovation'. Only knowledge allows us to achieve these two goals.”
