Day1 - pyCon2013 Notes

Hello World!!

After a long time updating my notes, learning’s in this post.

Some good one liner’s from Pycon2013

• WLT – We Love Typing
• DRY – Don’t Repeat Yourself

Today I attended Pycon 2013. This was my first python focussed learning session. Sessions were pretty good. Summarizing my notes of today's session

Session #1 - The first session was log management in inmobi 

• They have a framework built to store, manage all kinds of logs (Web Server Logs, DB Logs, Application logs, Cron Tab Logs) 
• Three steps were followed in collecting logs
• Collection of Logs – Apply Patterns – Fetch Logs
• Tools used include logstash, grok (ships with parse patterns) - http://logstash.net/ 

Author also provided other alternatives and tools for implementation

• Transport – flume, rsyslog, conduit, scribe
• Search and Analytics – hadoop, graylogz, elsa
• Storage – HDFS, Cassandra, Elastic Search
• Apache Falcon

Jordan Sissel is the brain behind logstash. His video session is also available in link

Session #2 – Django Framework beyond Basics

It was a well presented session. Although this was my first session on Django I could get the feel of the framework. Presenter Arun (http://Arunrocks.com)

Django – Web Framework. This is built on principles of Rapid App Development. How a typical web request is handled in Django framework 

• Models – Matter
• Views – Thinkers
• Templates – Should be dumb

Good Things about Django Framework

• Good Admin Interface
• Security
• Great Documentation
• Stable
• Batteries Included

Basic Definitions of Query Set (Object that interfaces with DB), Media Separate etc. Python implements class based views. Earlier it was function based generic views

Tools Discussed

• IDE – Pychan, PyDev, Emacs, Vi, Sublimetext
• Deployment Tools – Chef, Puppet, fabric
• Security Checks – ponycheckup.com for Django based sites
• ORM – SQLAlchemy

Session #3 – Third Session was Rapid development & integration of Real Time Communication in Websites

The session as pretty interactive. Demonstrating realtime video chat using google webrtc. https://github.com/cjgiridhar

Demonstrated the setup

• End User Requests sent to Tornado Web Server
• Using Web Socket / Ajax communication happens (video chat / live chat)
• Chat messages saved in Redis database

Tools

• Webserver – flask, bottle, tornado
• Javascript and webRTC
