I like to Build things (on the Internet)
The Internet is perfectFor Creation
For Distribution
For Disruption
For Monetization
For Success
For Failure
For LOLcats
Startups are like jumping out of a plane and figuring out how to
build the parachute as you fall.

The App
Pure Python
A Simple Flask App
Displays Facebook Images matching a word
Use Twitter Bootstrap for Style
Use Git for Version Control
Deploy to Amazon
The App
Lets get started...
Friends don't let Friends not use Git
Git is your friend
GitHub is your best friend
More Octocats at http://octodex.github.com
Lets git started
$ curl -u 'jsh2134' https://api.github.com/user/repos -d '{"name":"my_repo"}'$ git init my_repo$ cd my_repo$ git remote add origin [email protected]:jsh2134/my_repo$ vim README$ git add README$ git commit -m 'first commit'$ git push origin
What is Flask?
Lightweight Python web Framework
Like Django but SimplerUses all the best parts
~5000 Lines of CodeCan easily dig in if you need to debug or change
Leverages Jinja and WerkzeugWerkzeug debugger is incredible
The Simplest Flask App
from flask import Flaskapp = Flask(__name__)
@app.route('/')def hello_world(): return 'Hello World!'
if __name__ == '__main__': app.run()
And Now Some Flask Code
Jinja Templates
Separate the Python from the HTML
Add Logic to your HTML
Simple Syntax
Template Inheritance
Less gray hairs
Pause for Some Jinja Code
Boto
Python interface to Amazon Web Services
Create/Start/Stop Servers on DemandCan do everything actually
Boto is @&$?ing awesome
Actively Developed
AWS very Flexible
A Quick Boto Break
Fabric
Execute commands on remote server
Installation Scripts
Update Code
System Admin Tasks
We will use Fabric to deploy our app
Fabric Examples
The Final Code Base
