PyParallel: A Fast Parallel Version of Python
By combining asynchronous I/O with a shared-nothing architecture, PyParallel research project is able to execute code in a parallel context faster than it can using CPython’s normal interpreter. And it does this without removing the GIL. The secret, no reference counting or garbage collection of any kind.

Don’t jump the SQL ship just yet
The SQL language has been evolving steadily over the last two decades. At the same time, the verbosity caused by the JDBC API in Java client code and the lack of first class SQL support within the Java language have led to the introduction of ORMs such as Hibernate, which was later standardised into JPA and the Criteria API.If SQL and JPA are diverging, where will our data interaction patterns go?

Practical MQTT with Paho
MQTT is making the Internet of Things an interoperable and flexible world where the smallest devices can talk to the largest of servers. Obtaining valuable information from anything from a single temperature sensor to an industrial machine can be handled over an MQTT-based platform. What is MQTT and where do we find the libraries to talk with it? This article presents the Eclipse Paho project.
