How to setup AWS lambda function to talk to the internet and VPC

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.

So it might be really unintuitive at first but lambda functions have three states.

1. No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
2. VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
3. VPC with NAT, The best of both worlds, AWS services and web.

Convert a PDF to svg files. Note that this is pretty slow since it makes
subprocess calls to inkscape's PDF-to-SVG command line convert.

Requirements:
    - Inkscape (https://inkscape.org/)
    - pyPdf (http://pybrary.net/pyPdf/)
    - A '/tmp' directory. If not, you must pass in another directory.

My explanation of the main concepts in Rust

There are three main concepts with Rust:

1. Ownership (only one variable "owns" the data at one time, and the owner is in charge of deallocating)
2. Borrowing (you can borrow a reference to an owned variable)
3. Lifetimes (all data keeps track of when it will be destroyed)

These are fairly simple concepts, but they are often counter-intuitive to concepts in other languages, so I wanted to give a shot at

Cargo like npm

• cargo-watch watches over your project's source for changes, and runs Cargo commands
• cargo-edit add, remove, and upgrade dependencies by modifying your Cargo.toml

CLI

• clap // Command Line Argument Parser for Rust
• structopt // Parse command line arguments by defining a struct. It combines clap with custom derive.
