Types

A type is a collection of possible values. An integer can have values 0, 1, 2, 3, etc.; a boolean can have values true and false. We can imagine any type we like: for example, a HighFive type that allows the values "hi" or 5, but nothing else. It's not a string and it's not an integer; it's its own, separate type.

Statically typed languages constrain variables' types: the programming language might know, for example, that x is an Integer. In that case, the programmer isn't allowed to say x = true; that would be an invalid program. The compiler will refuse to compile it, so we can't even run it.

here's one reasonable approach to introducing someone to programming for the first time
# this file is NOT MEANT TO BE EXECUTED
#-----------------------------------------
# the following notes are related to a short presentation about how to think about programming basics
# the idea is simple: all programming languages basically have 4 common attributes that you can look for when
# you're trying to learn the new language: data, decisions, loops and flow
# the notes here are specific to Ruby but you can basically produce the same thing for any programming language
# echo is like puts for bash (bash is the program running in your terminal)
echo "Loading ~/.bash_profile a shell script that runs in every new terminal you open"
# $VARIABLE will render before the rest of the command is executed
echo "Logged in as $USER at $(hostname)"
# Load RVM into a shell session *as a function*
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
# Path for RVM
test -d $HOME/.rvm/bin && PATH=$PATH:$HOME/.rvm/bin

a quick intro the JS that focuses on functions
// to understand any system we must retain either control or visibility (or both)
// this is how you retain visibility
console.log('hello world')
// so now we can give up our need for control :)
// and along the way you'll see new words and language syntax. share your confusion!
// it's the greatest of gifts from a shameless heart and playfully curious mind.

good presentations

start with a story

  • help people relate
  • opportunity for some fun
  • make it real and relevant

talk about the numbers

  • data on the problem
  • data on the solution
class Window
SCALE = 100
class Collapsed < ArgumentError; end
attr_reader :low, :mid, :high, :max
def set(window)
# p "setting window to #{window}"
@low, @mid, @high = window
class NumberNotFoundError < ArgumentError; end
def render(points, length)
puts "_" * length
display = " " * length
markers = %w[\\ | /]
points.each_with_index do |p, idx|
display[p] = markers[idx]
end
puts "%#{length + 5}s %3s : %3s : %3s" % [display, *points]
# Put your answers here!
