# Software tools
- There are two options to taking this class. You can:

**.blue[Choice #1 ]** - Buying remote access to a Linux machine from the computer science club (CSC) is a great choice.
* It's cheap ($2 / term)
* Log into your account from anywhere in the world.
* They have everything you need installed on their servers. 
* **If in doubt, do this.**

**.blue[Choice #2]** - DIY - Instal everything on your own system.
* Read on to see what you'll need

## Your operating system

## Unix & Apple  <img src="pics/gnu-linux.png" width=55 height=55 align=left > <img src="pics/apple.png" align=left width=50 height=50>
- The key philosophy underlying Unix-like systems is that everything is represented as text.

- **Apple** machines are based on FreeBSD which is a unix variant. By default Macs have many command line utilities installed. You may have all the basic tools you need installed!

## Windows <img src="pics/windows.jpg" align=left width=50 height=50>
- **Windows** does not have such a clear design philosophy but unix-work-a-like tools are available to download for free

- Cygwin bash shell and many utilities 
    - "Cygwin is a large collection of GNU and Open Source tools which provide functionality similar to a Linux
      distribution on Windows."
    - http://www.cygwin.com

- Installing Cygwin:
    - https://cygwin.com/install.html
    - Here is another quick install slide that may be helpful: 
    http://www2.warwick.ac.uk/fac/sci/moac/people/students/peter_cock/cygwin/part1

- Make sure cygwin has installed:
    - **wget, lynx, wc, vi, vim, nano, grep, sort, uniq**
    - Also choose **bash** and **python**

- ** DON'T ** choose files that you don't need. You could end up taking up a lot of disk-space for things you won't use.

- Apple has kindly decided to package python, bash and all sorts of command line in the default install

- However, upgrading these packages manually is complex and difficult. Instead, there are different package manager
  software that will handle the upgrade process for you.

- Personally, I use **MacPorts** (https://www.macports.org/) to automatically handle installing software. 
    - Here is a how-to: https://astrofrog.github.io/macports-python/

- Many people use **HomeBrew** (http://brew.sh/) to do the same thing. "They" say it is better but MacPorts works for me and
    I have enough to do. *Warning*: I can't support this because I know so little about it!

- Your operating system may very well have python installed already.
    - If so, you may be able to skip the next steps if you're not sure
    you want to install external libraries.

- Here is a guide to installing Python on multiple operating systems
    - http://docs.python-guide.org/en/latest/starting/installation/

## Problems installing the software? <img src="pics/gnu-linux.png" width="211" height="211" align=right >

- Problems with software installation? Not enough time to do it?

- We'll try to help before class. Come early!

- **But buy a computer science club membership just in case!**
