How do you program a multicore computer? Easy - do it in Erlang. Erlang is a concurrent functional programming language designed for programming fault-tolerant systems. With share-nothing semantics and pure message passing, Erlang programs scales on multi

By combining all the above concepts, it is possible to abstract out a Thread Pool pattern in the JDK for your daily parallel processing solutions. This article will showcase code that can be built and run using the JDK along with your favorite database.

Recently there has been a lot of discussion about the concept of eventual consistency in the context of data replication. In this positing I would like to try to collect some of the principles and abstractions related to large scale data replication and t

Ruby on Rails, like most other programming technologies, now finds itself caught in the concurrency quagmire. While RoR has a streamlined focus on the Web application domain, parallelism isn't as limited in terms of domain, platform or application—it's

Erlang is going to be a very important language. It could be the next Java. Its main problem is that there is no big company behind it
