Deepak Giridharagopal explains the config management and automation tool Puppet, the concept of Immutable Deployments, and how Puppet DB (written in Clojure) allows to monitor and query systems managed with Puppet. Also: why PuppetDB is written in Clojure.
Ben Christensen explains how Netflix manages to stay online even with millions of users, the Hystrix fault tolerance library, how Netflix discovered reactive programming and why it ported Rx to Java.
David Nolen explains the ideas behind logic and constraint programming, how they're used in his Clojure core.logic library, Prolog, the features in the Oz language and Mozart/Oz, and much more.
Rich Hickey explains the basics of Datomic, its approach to transactions and query, Datalog, CAP, ACID and BASE, and much more.
Rich Hickey explains how immutability enables Datomic's features and facilitates programming (not just in functional languages). Also: Datomic and other NoSQL stores, Clojure Reducers and much more.
Stuart Halloway explains Datomic, programming transactional behavior with Datomic, Datalog and logic programming, programming with values, Clojure Reducers and much more.
Rich Hickey explains Clojure 1.4's extensible Reader, which allows to provide custom notation for data without the problems of Reader macros. Also: ClojureScript, Clojure in Clojure, and Avout.
Rich Hickey explains the ideas behind the Datomic database: why Datalog is used as the query language, the functional programming concepts at its core, the role of time in the DB and much more.
Howard Lewis Ship discusses Tapestry 5, changes he'd like to see in Java, Clojure, and Java/Clojure interoperability.
In this interview Joe Armstrong and Robert Virding, co-inventors of the Erlang language, talk about the future of the language, including its use in web programming, its ability to scale and more. The duo also discuss Erlang support for NoSQL databases, running the language on the Java Virtual Machine (JVM) and comparisons with other languages such as Google’s Go.
In this interview Ryan discusses Clojure with author Chris Houser. They cover Clojure's approach to classes, comparing and contrasting it with Java. Chris delves into they type of programming problem sets Clojure is best suited for, especially in relation to parallelism as the number of cores in computers increases and Clojure's applicability as or research language.
