Prework
=======
Welcome to Byte Academy
=======================
We've put together this program to get you all on the same footing before entering. You will be learning some basic git, Unix, JavaScript, and Python.
Our goal is for you hit the ground running when you come to campus.
The resources will build upon each other to whatever extent they can.
A lot of it is horizontal to other skills. So, if you are stuck on something, feel free to move on and come back to it later.
## Step 1
Make a [GitHub](https://github.com/) account.
#### Git and Unix
Pick a text editor to use. We recommend [Sublime](http://www.sublimetext.com/) or [Atom](https://atom.io/).
[Command Line Crash Course](http://cli.learncodethehardway.org/book/)
Make sure [Python 3.4.2](https://wiki.python.org/moin/BeginnersGuide/Download) and [Node](http://nodejs.org/download/) are installed on your computer
[Try git](try.github.io)
## Step 2
[Git Immersion](http://gitimmersion.com/)
Do these tutorials:
* [Command Line Crash Course](http://cli.learncodethehardway.org/book/)
* [Try git](try.github.io)
* [Git Immersion](http://gitimmersion.com/)
* [Code Academy HTML/CSS](http://www.codecademy.com/en/tracks/web).
## Step 3
Work through the practice problems provided. We recommend starting with front end, moving to JS, and finishing with Python.
Here are some resources to help you on assignments, as well has good reads.
#### Front End
Do Code Academy's [HTML/CSS course](http://www.codecademy.com/en/tracks/web).

[A compilation of wireframing articles](http://www.gracesmith.co.uk/get-wireframing-the-all-in-one-guide/)
#### JavaScript

Regular Expressions
===================
Regular Expressions (regex for short) are a way to represent patterns in strings. They aren't as bad as people make them out to be. When used on the right problem, they are a great solution.
Go to [Rubular](http://rubular.com/). We're going to sandbox inside it a bit to get acquainted with regex syntax. At the bottom of the page is a regex cheat sheet.
Note: Depending on the language, you may have to escape certain characters. For example, instead of `a{3}`, you may have to type `a\{3\}`.
Also, be careful with periods (`.`). A period means any character in regex, so you have to escape it if you want to pattern match a period.
Here are some examples of regex and matching string patterns:
* `a{3}` => `aaa`
* `a{3,}` => `aaaaaaaa`
* `[a-z]` => any lowercase letter
* `[A-Z]{4,6}` => between 4 and 6 uppercase letters, ex. `FASDV`
* `.` => any character
* `\w\.` => `_.`
* `hello\d?` => `hello` or `hello5`
* `[a-nO-Z]*` => abcOZZ
Make a regex to match each of these strings:
* match 'byte academy' 3 different ways
* an 8 character password, do not allow non word characters
* an 8 character password that has at least 1 number and 1 capital letter
* byteacademy@example.com
* byte.academy@example.com
* byteacademy22@example.co.uk
See if you can get all three with 1 regex, but not invalid emails (not having an @, etc...)
