Trend toward open-source • Virtually all programming languages • Virtually all popular database systems • Virtually all popular web servers • What percent of new phone systems use open-source? Wednesday, March 4, 2009

Languages are hard to write • Open-source languages are converging on VMs Java Virtual Machine Javascript Ruby Python Groovy Scala Clojure Wednesday, March 4, 2009

Telephony doesn’t have a VM yet • Must be fully open-source • Must support SIP • Must handle media • Must allow sophisticated bridging • Must cluster well • Must scale well • Legacy doesn’t matter • Hardware support doesn’t matter Wednesday, March 4, 2009

Simplicity Trend • Case in point: Drizzle fork of MySQL • Case in point: Dynamically-typed programming languages • Case in point: REST versus SOAP • Case in point: JSON or YAML over XML • Case in point: Ruby on Rails over “enterprise” Java Wednesday, March 4, 2009

Trend: The Long Tail Popularity Applications Wednesday, March 4, 2009

Converging Trends • Trend toward polyglot programming • Trend toward open-source • Trend toward a unifying programming language VM • Trend toward simplicity • Trend toward “Long Tail” applications • If you want a deﬁnition of “Voice 2.0”, this is it. Wednesday, March 4, 2009

Adhearsion is... “Adhearsion is a new way to write voice-enabled applications. It's not just an API or library — it's a fully-featured framework, the ﬁrst of its kind, designed for maximal code reuse and intuitiveness. The name \"Adhearsion\" is a combination of \"adhesion\" and \"hear\" because Adhearsion shines best when integrating technologies with voice.” from Adhearsion.com Wednesday, March 4, 2009
