Computers and Programming

➲ Turing provided an influential

formalization of the concept of the algorithm and

computation with the Turing

machine. _{Alan Turing,}

(1912–1954)

"It is possible to invent a single machine which

can be used to compute any computable

(6)

Computer Programming

➲ 1940s:

 Assembly language

 The first programming language: Plankalkül

➲ 1950s, 60s:

 FORTRAN, LISP, COBOL, BASIC

➲ 1970s:

 Object orientation (e.g. Simula, Smalltalk)  C

➲ 1980s:

 C++, Ada, Perl

➲ 1980s: (Internet)

 Java  Python  C#

(7)

Programming Languages

➲ Java: is a cargo ship. It’s

very bulky. It’s very

enterprise~y. It can also carry a lot of weight. Will

carry a project, but not very fun to drive.

➲ PHP: is a bamboo raft. A

series of hacks held together by string. Still keeps afloat

(8)

➲ C/C++: is a nuclear submarine. The

instructions are in 'Japanese', but all of the hardware is optimized for performance.

Clumsy, in many aspects can be

dangerous, but it regularly goes where other boats go when they have holes!

(9)

Languages

➲ Python: Small boat with outboard engine. Easy

to learn, fun to ride, no need to have a license, very Dutch. Kids love it! Many use it as a hobby.

interpreted and dynamically

typed and is very suited for

interactive work and quick

prototyping,

Python is now the most popular introductory teaching language at Top U.S. Universities; MIT, Stanford

Why Python

-Readable code (If you understand English, you already

understand Python)

-Easy to learn

-If you know Python, you can work with almost any

Python with little effort

-High-performance computing -Powerful

-Python is broad -Python is fast -Python is free

-Python is efficient

You are looking for a job, which language should you learn?

How to go abut learning...

➲ First

 Ignore the details and focus on important principals!  Writing small programs is better than reading long

ones!

 Find a few good on-line references and use them often.

➲ Then

 Take a fairly involved problem and write your own program.

➲ Later

 If you are to write fairly long programs, details are also important. Try to remember how, if not why.

Warnings do Matter

(not only errors)

➲ A man is smoking a cigarette and blowing

smoke rings into the air. His girlfriend becomes irritated with the smoke and says, "Can't you

see the warning on the cigarette pack? Smoking is hazardous to your health!"

➲ To which the man replies, "I am a programmer.
