This document provides an overview of an introduction to programming workshop that will cover Ruby on Rails. It describes a 12-week TechLadies bootcamp program that teaches coding to help women find software jobs and internships. It outlines the workshop agenda which will cover what programming is, using the terminal, Ruby language basics, and building a computer game program and cloud computer. It also provides example Ruby programs and resources for learning more.

17. Overview
• What is programming
• Introduction to Terminal
• Ruby programming language
• Write a computer program game
• Your own cloud computer (if we have time)

18. What is Programming
Computer programming (often shortened to
programming) is a process that leads from an
original formulation of a computing problem to
executable computer programs.

Computer programming (often shortened to
programming) is a process that leads from an
original formulation of a computing problem to
executable computer programs.

19. What is Programming
A process where we
• Define & understand problems
• Decide how to solve the problem step by step
• Writing code in the selected programming
language

20. Computers are Stupid
• They do not think as humans
• They only do what we tell them to do

21. FizzBuzz
For each number from 1 to 100, if a number is
divisible by 3, write “Fizz”, whereas if a number is
divisible by 5, write “Buzz”. For all other numbers, just
write the number.

22. Understanding the Problem
• Number 1 -> write 1
• Number 3 -> write Fizz
• Number 5 -> write Buzz
• Number 15 -> ?

23. Example program
(Assembler)

28. Example program (Erlang)

29. Example Program (Ruby)

30. Example Program (Ruby)

31. Terminal
• Terminal is a text-based interface to the operating
system
• Think Windows Explorer / Finder, but in text
• More powerful than GUI, but header to learn
Editor
• A tool which we can edit texts in files

32. Ruby Language
• Ruby is a programming language, it allows us to
write programs that will be run on computers
• It’s very high-level, it looks a lot like the human
language

33. Language Syntax
• Computers are stupid
• They can’t understand our words, even very basic
sentence
• Strict sets of vocabulary & syntax
• E.g. if … else (but not if … otherwise)

34. Programming Syntax
• the arrangement of words and phrases to create
well-formed sentences in a language

35. Guess the Number
• Program chooses a random number between 0
and 100
• Player tries to guess the number, getting a hint
(“too low” or “too high”)
• Game ends when player guesses the number

36. 15 Minutes Break

37. Guess the Number v2
• Program tells player how many tries she needed to
guess the number correctly
• Program shows player all the previous tries

38. Guess the Number v3
• Program asks for player’s name, and remembers
the last result of each player
