An Elixir for the Web's Future

The web has evolved; has your tech stack?

The evolution of the web has been fueled by hacks, workarounds, and abuses. This evolution has spawned many tools and techniques along the way. This talk will reflect on the web's history and what it means for the web's future. Armed with this knowledge we will examine the functional programming language Elixir and how its philosophy so perfectly fits the future of the web. The technical part of the talk will examine the architecture and code of an example JavaScript (Backbone?) application using websockets for real time communication and collaboration with an Elixir backend.

Notes:

• Discuss history and future of web:
