The principal political binary of the past century was the political 'left versus right'. But in the 21st century the binary has shifted -- the battleground now is 'open versus closed'. Those states and societies that embrace economic, political, and cultural openness will have a better shot at competing in the software and technology-driven future, argues Alec Ross, author of the new book The Industries of the Future.

Ross, who worked on the first Obama presidential campaign and was the advisor on innovation to Hillary Clinton when she was Secretary of State, joins the a16z Podcast to discuss his views on the industries (and cities) of the future, how they are playing out across a 196-country chessboard, and what we all can do to prepare ourselves and our children for what is to come.

8 Things Every Person Should Do Before 8 A.M.

Jonas Bonér, CTO of LightBend and creator Akka, discusses using Akka when developing distributed systems. He talks about the Actor Model, and how every Microservice needs to be viewed as a system to be successful. 

Why listen to this podcast:

 - Akka is JVM-based framework design for developing distributed systems leveraging the Actor Model - an approach for writing concurrent systems that treat actors as universal primitives and the most successful model with abstraction has been streaming
 - Circuit breakers in Akka are a backup and retry policy; they protect you by capturing failure data and allow you to roll back 
 - Every Microservice needs to be viewed as a system, it needs to have multiple parts that run on different machines in order to function and be fully resilient - thus is a Microsystem
 - Two different trends have emerged when it comes to hardware and environments: one is the trend toward Multi-core, the is a movement toward virtualized environments and the cloud
 - Saga pattern of managing long running transactions in a distributed system fits very well with messaging style architectures

Kellyanne's Alternative Universe - The Atlantic - Molly Ball

The philosophers he influenced set the stage for the technological revolution that remade our world. Read the full text version here: https://www.theatlantic.com/technology/archive/2017/03/aristotle-computer/518697/

How Aristotle Created the Computer - The Atlantic - Chris Dixon

The United States periodically debates whether to do more or less abroad. Trump won by straddling the divide and promising both. But he can’t possibly deliver.

The Brilliant Incoherence of Trump’s Foreign Policy - The Atlantic - Stephen Sestanovich

Wesley Reisz talks to Sachin Kulkarni, Director of Engineering at Facebook, about the engineering challenges for Facebook live, and how it compares to the video upload platform at Facebook.

Why listen to this podcast:

 - Facebook Infrastructure powers the board family of apps including the Facebook app, Messenger and Instagram.  It is largely a C++ shop.  There is some Java and Python, and the business logic is all done in PHP.  The iOS apps are written in Objective C and the Android apps are in Java.

 - The video infra team at Facebook builds the video infrastructure across the whole company.  Projects include a distributed video encoding platform which results in low latency video encoding, video upload and ingest.

 - Facebook Live does encoding on both the client and the server.  The trade-off between encoding on the client side and the server side is mostly around the quality of the video vs. latency and reliability.

 - Facebook gets around 10x speed-up by encoding data in parallel compared to serial.  

 - They also have an AI-based encoding system which resulted in 20% smaller files than raw H.264.
