An Embedded Java 8 Lambda Expression Microbenchmark

It's been a long road, but Java 8 has finally arrived.  Much has been written and said about all the new features contained in this release, perhaps the most important of these is the introduction of Lambda Expressions.  Lambdas are now intimately integrated into the Java platform and they have the potential to aid developers in the traditionally tricky realm of parallel programming.

Raspberry Pi and Java SE: A Platform for the Masses

One of the more exciting developments in the embedded systems world has been the announcement and availability of the Raspberry Pi, a very capable computer that is no bigger than a credit card.  At $35 US, initial demand for the device was so significant, that very long back orders quickly ensued.
