What will go wrong? Everything. This won't be easy for anyone.

"If debugging is the practice of removing bugs from software... Then programming must be the practive of adding them." – E. W. Dijkstra

The best thing you can learn as a beginner is how to debug.

A Typical Day here at GA...
Time What?
09:00 - 10:00 Warmup Exercise
10:00 - 01:00 Code Along
01:00 - 02:00 Lunch
02:00 - 02:30 Review
02:30 - Beyond Labs / Homework

Breaks for morning and afternoon tea last for twenty-ish minutes and are whenever works best.

In terms of homework, we like to keep you busy until 9 or 10.

We have office hours here in Sydney (except during Week 6 - we have the Spit to Manly.)

Introduction to Markdown

What is Markdown?

Markdown was initially created by John Gruber (of Daring Fireball) as a simple way for non-programming types to write in an easy-to-read format that could be converted directly into HTML.

Markdown uses a very simple formatting syntax to accomplish the same thing that HTML does. The difference is that it's simpler than HTML and you don't have to worry about opening and closing tags. It also doesn't have all of the menus associated with most text editing programs. To format text, Markdown uses punctuation and characters you're already familiar with.

How do you write it?

This is quite a good place to learn it.

To create a paragraph...

This is a paragraph, it has nothing unusual.

To create headings...

To create headings, prefix the text with hashes (from 1 hash to 6 hashes - more hashes, less important)

# This is an H1
## This is an H2
### This is an H3
#### This is an H4
##### This is an H5
###### This is an H6

To use inline styles...

For italics, wrap the content in underscores, for bold, wrap the content in asterisks.

_This is in italics._

**This is bold.**

_You can **combine** those two things quite easily._

To create lists...

# For unordered lists, prefix text with a +, - or *

- This is one list item
- This is another

* This is one list item
* This is another

+ This is one list item
+ This is another

You can write unordered lists in a bunch of different ways!

# For ordered lists. Just write the number and a period after it

1. This is a list item
2. This is another list item

To create links...

To create links, select the things that you want to act as a link and put square brackets around them. Immediately following, have round brackets with the URL.

OR! Just put the link on the page.

[This](https://generalassemb.ly/) is a link to General Assembly.

https://generalassemb.ly/

To put an image in the file...

To put an image in the file, have an exclamation mark, followed by square brackets with a caption in it, which is in turned followed by round brackets with a URL and an optional title.

![This is Zac.](https://pbs.twimg.com/media/CLOZKEGUsAA9Wym.jpg "An optional title")

To quote someone (using a blockquote)...

To use a blockquote, prefix some text with a >

> This is a quote

To put code on the page...

To put code on the page, wrap some backticks (`) around the code.

\```
var x = 5; // This is a comment
if ( x < 5 ) {
  console.log( "something." );
}
\```

Alternatively, you can have inline code by wrapping text with a single ` .

This is an inline piece of code - ` var x = 5; `.

The Command Line

It's probably worth downloading iTerm 2.

Web programmers have to live on the command line. It gives us fast, reliable, and automatable control over computers. Web servers usually don't have graphical interfaces, so we need to interact with them through command line and programmatic interfaces. Once you become comfortable using the command line, staying on the keyboard will also help you keep an uninterrupted flow of work going without the disruption of shifting to the mouse.

The command-line interface, is often called the CLI, and is a tool, that by typing commands, performs specific tasks. It has the potential to save you lots and lots of time because it can automate things, loop through items etc.

date - Will print the current date and time

which date - Will show the relevant file (will probably return /bin/date)

pwd - Stands for Print Working Directory, will show you where you are in your computer

mkdir - Stands for Make Directory

rmdir - Stands for Remove Directory

clear - Will clear the screen (ctrl + l will do this as well)

reset - Will reset your terminal

cd - Stands for change directory

cat filename - Will show you the contents of the specified file

whoami - Will show the logged in user

ps - Will you show you all running processes

ps aux - Will show you all of the running processes with more details

top - Will show you the Table of Processes

grep - Stands for Global Regular Expression Print - useful for finding files or content

ls- Short for List. This will show you all of the files and folders in the current directory

ls /bin - Will show you all terminal commands

man - Stands for Manual. To use it, follow the man command with another command (i.e. man grep).

Most commands will have additional flags. A flag is a request for more information.

A good example of this is the following:

> ls
Applications Documents Desktop etc.
> ls -l
drwx------   6 jackjeffress  staff   204 16 Mar 15:39 Applications
etc.

#https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/ls.1.html
# cd can do a lot of things!

> cd
# Will take you back to your "home folder"
> cd /
# Will take you back to your "root folder"
> cd FolderName
# Will take you into the specified folder name
> cd FolderName/AnotherFolderName
# Will take you through FolderName and then into AnotherFolderName
# We can make folders in the CLI by using mkdir

> mkdir Projects
# Then we can move into it
> cd Projects
# ls will show most of your files (ones that aren't prefixed by a .)
> ls
# ls -la will show every file (even hidden files)
> ls -la
# This will change to the current directory
> cd .
# This will open the current directory in Finder
> open .
# This will go back to the previous directory
> cd ..
# If you hit tab at this point, it would autocomplete for you
> cd pro
# This will create a markdown file called README
> touch README.md
# To open an application in terminal (can use any application that you have)...
> open -a "Sublime Text"
# This will open the file and show the contents
> cat books
# Will show you the contents, pipe it into the sort program. This doesn't change the original!
> cat books | sort
# The pipe character pipes the output to a command
# This will sort the contents and books, and put the sorted contents into the sorted_books file (it will create the file if necessary)
> cat books | sort > sorted_books
# This will rename the sorted_books to books (and will overwrite the books file if it already exists)
> mv sorted_books books
# This will open and show the contents and books, and shows only lines that have the word script in them (case sensitive!)
> cat books | grep script
# To copy a file, the command is cp (this needs parameters - or arguments. It needs a source and a destination).
# cp source destination
> cp books my_books
# To remove things, use the rm command (this doesn't get moved to your trash! It will delete it permanently and is impossible to undo)
> rm my_books

What happens when we run commands?

# It will go through all of the folders and files that are shown when we run the following command, and use the contents of the files to decide whether it can run that particular program or command
> echo $PATH

Here is a basic bash profile.
