Programming for Parrallelism: The Parallel Hierarchies Pattern
Multi-core processors offer new performance opportunities. Shekhar Borkar from Intel highlighted, however, that software development practices have to be retooled to leverage this potential. In this vein, Prof. Jorge L. Ortega-Arjona from the National Autonomous University of Mexico has recently introduced a new architectural pattern for parallel programming: Parallel Hierarchies pattern.

Erlang's Mnesia - a distributed DBMS for highly scalable apps
Not every application has the scalability requirements of Google, Flickr or Amazon, however the ideas behind the Mnesia DBMS are compelling: a fast, in-process DBMS that takes advantage of concurrency, with the ability to replicate tables across distributed nodes for high scalability and fault tolerance.

Is Erlang the Java for the concurrent future?
The future of computing is going to be concurrent. Even desktop CPUs are multicore nowadays, and when customers are buying more and more CPUs to their servers, they expect their applications to scale well to utilize their new investment. But that's not going to happen with many software systems of today. Can Erlang help?

The Futures of Ruby Threading
Ruby's thread system is about to undergo big changes in Ruby 1.9, possibly moving from user space threads to kernel threads. Or not. A recent interview with Matz and Sasada Koichi shows some new ideas that are considered. We take a look at the different possible future Ruby threading systems.
