Daira Hopwood introduces Noether, an experimental language meant to write more secure, robust and efficient programs, being built on multiple layers satisfying different levels of symmetries.
Gilad Bracha explains how to distinguish FP hype from reality and to apply key ideas of FP in non-FP languages, separating the good parts of FP from its unnecessary cultural baggage.
Clayton Bauman introduces Babel, an open source language implemented in C, targeted for cloud computing. Other features: interpreted, untyped stack-based, postfix, supports arrays, lists and hashes.
Miles Sabin and Edwin Brady exemplify what can be done with a language with dependent types, what are the limitations and what could be done in the future when dependent types reach maturity.
Mike Falanga shows several C# and F# solutions to common programming problems, comparing how well each language enhances the ability to draw accurate conclusions about the code.
Daniel Gregoire introduces Gershwin, a stack-based, concatenative programming language with a Clojure runtime that targets the JVM.
Bjarne Stroustrup discusses features that might appear in C++14: braces for copy initialization, return type deduction in functions, generic (polymorphic) lambdas, user-defined literals, etc.
Creighton Kirkendall discusses how polymorphism is implemented in Clojure, Ocaml, Haskell and Scala.
Matthew Flatt introduces Racket, an extensible programming language useful to create new syntactic forms and construct entirely new programming languages.
Rob Pike explains how Google designed Go to address major development issues they encounter while using other languages: long build times, poor dependency management, lack of robustness, etc.
Ostap Cherkashin and Julius Chrobak present writing readable and extendable rich data manipulation code with Bandicoot.
