Pivotal Analytics Workbench Demonstrates the Ease of Switching Between FDR InfiniBand and 40Gigabit Ethernet

Pivotal’s Analytics Workbench offers partners the power of a 1000-node Hadoop cluster, providing a publicly-available data processing powerhouse, free of charge, for 90 day engagements. It also offers a powerful platform for testing. To this end, the AWB team collaborated in October with Pivotal’s partner Mellanox Technologies to test the effect of flipping the cluster’s network connection between InfiniBand and Ethernet on-the-fly, affording customers unparalleled flexibility for cost savings in their Hadoop deployments. This approach also proved they were able to run the cluster in mixed mode. Mixed mode allows you to use one vendor and bridge separate network-connected platforms—for example, connecting a Hadoop cluster to both EMC storage arrays and VMware vSphere. Such an approach reduces cost, difficulty, and latency.

All evidence points to OOP being bullshit

Object Oriented Programming (OOP) as an idea has been oversold. The most commonly used languages in use today are designed around the idea of OOP. Extremist languages like Java force you to think of everything in terms of objects. But is Object Orientation (OO) a good idea? Does it have problems? Is it the right tool for everything? Let's explore some of these questions in a slightly tongue in cheek and cathartic rant.
